North Lake is an urban freshwater wetland, and like other wetlands in the Perth metropolitan region, Western Australia, has become nutrient enriched, with the accompanying problems of algal blooms, decay, odour, infestation with midges and aesthetic deterioration. A study of the water quality of the lake was undertaken to quantify the variation of phosphorus, nitrogen and chlorophyll-a, and the sediments store of nutrients and their release with pH. The dominant algae in the lake, Microcystis, was found to be limited in growth by nitrogen because of the high availability of phosphorus (> 0.1 mg/l), and likely by light because of self-shading (chlorophyll-a > 0.3 mg/l). Sediments released a substantial amount of nutrients as pH rose above 8.5. Together with a parallel study of the nutrient budget of the lake, a management strategy has been derived to overcome the problem of nutrient enrichment that could be applied to other wetlands in the metropolitan region.

The Gnangara Mound is an area of elevated sandy soil on the Swan Coastal Plain to the north of Perth. It constitutes a major groundwater resource for metropolitan Perth. Sixteen wetlands on the Mound had total phosphorus concentrations of 12-462�g L-1, the high values being attributed to agricultural and urban activity. Sediment concentrations of total phosphorus and total nitrogen were 61-954 and 1212-16739 �g g-1, respectively. Conductivities were 505-10270 �S cm-1, and pH values were 3.3-9.3. Only one wetland was highly coloured (79.9 8440 m-1), with an E4/E6 ratio of 4.6. Chlorophyll a concentrations were 0.01-130.8�g L-1; in wetlands with low gilvin concentrations, Myxophyceae dominated, whereas wetlands with higher gilvin concentrations had large numbers of diatoms and Chlorophyceae. The highly coloured wetland had the lowest chlorophyll a concentration despite high nutrient concentrations, supporting the hypothesis that the consequent reduction in light or other associated factors are important in maintaining low phytoplankton biomass in dystrophic wetlands of the region, particularly those on Bassendean sands.

Abstract Catering for diversity within birth to 5-year-old settings continues to be an on-going concern for policy makers and educators worldwide. This research contributes to discussion on the value of children’s literature in achieving international principles of diversity and, in particular, the Principles, Practice and Outcomes outlined in the Australian Early Years Learning Framework. The article considers the selection and use of children’s literature related to diversity, as well as what influences these processes. Seventeen educators from five long day care centres located in or near the Perth metropolitan area participated in the study. Data were drawn from interviews and a book audit. The findings revealed educators had limited understandings of the role of literature in acknowledging and valuing diversity and rarely used it to promote the diversity-related outcomes of the EYLF. The key challenges which emerged from the findings concerned beliefs of educators, professional learning and the application of the EYLF in practice.

Assessment of areas suitable for inclusion in a comprehensive, adequate and representative (CAR) reserve system has been based primarily on distribution of original native vegetation and occurrence of vertebrates, particularly birds and mammals. However, reliable predictors of vertebrate and floristic diversity are not necessarily adequate predictors of invertebrate diversity. We sampled the earthworm fauna of the Perth metropolitan Swan Coastal Plain (SCP) to examine whether vegetation-based criteria are sufficient for identifying a conservation estate for native earthworms. Twenty-one native species were collected from 136 sample localities. All five previously described native species from the region and three native species previously collected but not formally described were again collected, while 13 previously uncollected species were found. Species abundances of native earthworms were uneven, in common with species-abundance relationships for many other invertebrate assemblages, with 10 singleton occurrences of species and few common species. Species diversity increased away from the coast across the sandy geomorphic units Quindalup, Spearwood and Bassendean. Our study did not resolve whether dlifferences in earthworm faunas reflect the gradient in soil qualities across these units, gradients in species-area effects, habitat diversity effects or a combination of these. Blocks of remnant vegetation identified in the Western Australian Government's Bush Forever plan as containing natural areas of regional conservation value are also likely to support at least one native earthworm species. However, many of the blocks of remnant vegetation so identified are not within the formal conservation estate. Two species identified in this survey fortuitously persist only in remnant vegetation patches not considered regionally significant. Actual regional diversity was estimated to be 38 native species, indicating many uncollected relatively rare species. Although earthworms are a low diversity group compared with other invertebrates, the localized distributions of most species indicate that the formal conservation estate does not provide adequate protection. Ongoing degradation of unprotected remnant vegetation will result in extinctions of localized invertebrate species.

This paper reports on the apparent displacement of native and exotic ants from gardens in the Perth Metropolitan region by the coastal brown ant (Pheidole megacephala (Fabricius)). Twelve gardens were sampled, four with P. megacephala present, and eight (the controls) where the ant was judged to be absent. Eight out of the 26 ant species recorded (including the coastal brown ant) were introduced. Ninety-two per cent of pitfall trap contents comprised the four most abundant species: P. megacephala, lridomyrmex chasei (Forel), Tetramorium simillimum (F. Smith) and Paratrechina ?obscura (Mayr). Three of the four P. megacephala-dominated gardens were depauperate of almost all other ant species. The fourth P. megacephala-infested garden had a relatively small number of coastal brown ants (104), and the highest number of ant species was found in that garden. The removal of this outlier garden left an average range of one to three species for the other three P. megacephala-infested gardens. Control gardens had between five and 12 ant species. Total ant abundance ranged from an average of 1 027 per P. megacephala-infested garden (increasing to 1 171 if the outlier garden is removed) to 146 at control gardens. There was a significant difference both in ant richness and ant abundance between the controls and P. megacephala-infested gardens (P < 0.05). This remained the case when figures for coastal brown ants were excluded from calculations.

The article attempts to present dilemmas related to shaping metropolitan policy in Canada, and then relate them to problems occurring in Poland. It is a part of the debate on seeking the right governance configurations and discourses in response to the communities’ needs. Particular attention is paid to the characteristics of the scales of governance and socio-spatial relations in the Toronto metropolitan area. The article has been divided into four main parts. Part one outlines the theoretical framework and the context of the conducted analyses. Part two describes the structures and processes of regional and metropolitan governance in Southern Ontario, with the earlier reference to the institutional conditions and directions of reforms characteristic of the whole of Canada. Part three of the study concerns the governance arrangements that may constitute important reference points for the scientific and political discourse taking place in Poland. Part four is an attempt to capture the similarities and universal premises that have a decisive influence on the processes of forming metropolitan structures and policies, both in Canada and in Poland. The assumption was made that, despite different historical and socio-cultural conditions, comparing Canadian and Polish experiences is justified, necessary and possible. Firstly, due to the reason that socio-spatial relations in various territorial systems are subject to the same development processes and the accompanying processes of transformation and adaptation. Secondly, residents (members of local, metropolitan, regional, national and supranational communities) have similar needs and expect a high quality of life. Decision-makers and actors of political scenes in different geographical spaces have (or may have) the same technologies, ways of information processing, access to knowledge and knowledge of socio-economic processes. They also face challenges related to the inclusion of citizens in decision-making processes. The analysis of metropolitan processes in both countries emphasizes the differences resulting from various historical and economic contexts of development and also makes it possible to identify universal mechanisms and regularities independent of these contexts. The practice of metropolitan policy proves that the process of re-territorialization of power structures and governance is shaped as a resultant of the impact of forces and interests at all levels of territorial authorities: central, regional and local. Based on the analysis of the processes of the formation of metropolitan structures in Canada and Poland, it can be stated that the rank and position of regional authorities play a key role in it. In Canada, strong regional authorities initiate actions for the shaping of metropolitan structures and formulate the scope of their competence and organization. The importance of central authorities for the dynamics of metropolitan processes is secondary in this case. The weakness of regional authorities in Poland leads to the inability to give metropolitan processes the dynamics of development and the legislative rank adequate for the role played by urban regions in the socio-economic development of the country. As evidenced by the example of Toronto, the evolution of the governance system in practice initiates the process of self-learning the system which goes from one to another phase of development, improving the quality of its operation. In Poland, however, the process of creation of governance structures adequate for realistically existing functional metropolitan areas has been stopped, notably, due to the unfavourable political decisions at the central level.

The level of commuting in cities is an important indicator of the efficiency of urban spatial structure. Recent research has come out in support of land use policies that promote balancing the number of employment opportunities and residents in local geographical units to reduce excess commuting. This study explores three employment self-sufficiency indices: job-worker balance (JWB), employment self-sufficiency (ESS) and employment self-containment (ESC), as measures for reducing the level of commuting. Using the case of Perth, Western Australia, we perform a trip-based evaluation of these three variables and investigate their effect on commuting time through statistical correlation. The results reveal that JWB, ESS and ESC levels are relatively poor across the metropolitan region. Higher ESS correlates with lower inflow travel time, but better JWB and higher ESC do not necessarily lead to shorter travel times. The findings of this study suggest that policies solely relying on these measures may not be effective in reducing commuting times. ESS and ESC do not account for the component of the trip outside the zone, which can misrepresent the level of commuting in an area. Incorporating travel time in these measures can complement their reliability, and better represent overall commuting levels within an urban structure.

CHILDREN'S LITERATURE IS IMPORTANT because it nurtures emotional, social, creative and cognitive development, and gives children opportunities to appreciate and respond to diversity. In particular, literature that portrays racial and cultural diversity is a powerful means of promoting understanding of others while affirming individual identity. However, the limited number of studies about the nature and use of literature that reflects diversity in early childhood settings prompted this study, which investigates the nature of book collections in five long day care centres in the metropolitan region of Perth, Western Australia, with a specific focus on the extent to which they reflect racial diversity. Qualitative data was drawn from an audit of the children's book collections (2377 books) across each of the five centres. The findings revealed a lack of representation of racial diversity in those collections and where racial diversity was portrayed, non-dominant cultures were commonly misrepresented through stereotypical images often portraying outdated perspectives.

Holocene prograded coastal sequences at Becher/Rockingham, southern Western Australia, contain a detailed record of sea level over the last 6400 yr. Radiocarbon dating and use of a distinct stratigraphic indicator as a sea-level marker permit reconstruction of sea-level history and suggest that the sea was at least 2.5 m above present datum about 6400 yr B.P. before falling to its present level. No evidence was found for eustatic fluctuations of the scale proposed by R. W. Fairbridge [1961,in“Physics and Chemistry of the Earth” (L. H. Ahrens, F. Press, K. Rankema, and S. K. Runcorn, Eds.), Vol. 4, pp. 99–185, Pergamon, Oxford]. The sea-level record preserved on this coast can be explained by hydro-isostasy, tectonism, or eustasy, acting individually or in concert. Without a fixed reference point or analogous data from other locations, a firm conclusion on which mechanism(s) has(have) operated could not be reached. Published sea-level data from this and other coasts are often insufficiently detailed to compare with this study. Application of the techniques of this study to analogous sedimentary sequences elsewhere will provide data of comparable accuracy that would contribute to a more precise understanding of relative sea-level movements in the late Quaternary.

Byblis Salisb. is a small genus of carnivorous plants with adhesive traps in the Lamiales family Byblidaceae Domin. There are two perennial species (B. gigantea Lindl. and B. lamellata Conran & Lowrie) with restricted ranges in Western Australia, where they experience a Mediterranean climate. The critically endangered B gigantea is endemic to the Swan River drainage area, now entirely within the Perth metropolitan area, whilst B. lamellata is restricted to the coastal region North of Perth. The genus also contains six currently recognized annual species (B. aquatica Lowrie & Conran, B. filifolia Planch., B. guehoi Lowrie & Conran, B. liniflora Salisb., B. pilbarana Lowrie & Conran, and B. rorida Lowrie & Conran) which inhabit the tropical and semi-arid regions of Northern Australia. The genus also extends to the island of New Guinea (Lowrie 2013; McPherson 2010). All species are found in substrates which are very nutrient-poor (Lowrie 2013; McPherson 2010) and share habitats with representatives of other genera of carnivorous plants (particularly Drosera, but also Utricularia and Nepenthes). Although there are important morphological differences between the Byblis species, all share the same basic structure in that they produce stems from which radiate filiform leaves. Another feature common to all species is the ability to produce fast concentrated growth in response to seasonal rainfall. (Bourke, pers. comm.). It has been observed on many occasions that all Byblis species play host to Miridae bugs from the genus Setocoris (Bourke, pers. comm.). A mutualistic relationship has been proven to exist between another viscid plant genus Roridula and a different genus of the family Miridae, Pameridea (Anderson & Midgley 2003). A similar relationship is strongly suspected in Byblis (Lowrie 2013; Cross et al. 2018).

AbstractSince the Industrial Revolution, the geographical extent of cities has increased around the world. In particular, following three decades of rapid regional economic growth, many Asian megacities have emerged and continue to expand, resulting in inevitable short-term urban redevelopment. In this region, the microclimatic impacts of urban redevelopment have not been extensively investigated using long-term in situ observations. In this study, changes in surface sensible heat exchange, heat storage, and anthropogenic heat emissions that are due to urban residential redevelopment were quantified and analyzed on the basis of a 3-yr micrometeorological record from the Seoul, South Korea, metropolitan area. The results show that, following urban redevelopment of compact high-rise residential buildings, 1) the daily minimum air temperature near the ground surface increased by ~0.6 K; 2) the ratio between surface sensible heat and net radiation increased by from ~9% (summer) to 31% (winter), anthropogenic heat emissions increased by from 7.6 (summer) to 23.6 (spring) W m−2, and daily maximum heat storage ranged from 35.1 (spring) to 54.5 (summer) W m−2; and 3) there was a transition of local circulation with changes in the surface properties of heat sources and roughness.

Brown and Root has participated in extensive investigations of the effects of the discharges from Perth's Ocean Outlets, as part of the Perth Long-Term Ocean Outlet Monitoring (PLOOM) Programme (1995 to 2001). The major environmental concern with these discharges is the potential for nutrients in the wastewater to stimulate excess primary production in the sea. PLOOM, and its predecessor, the Perth Coastal Waters Study, have been instrumental in developing parameters for the measurement of the performance of Perth's ocean outlets. These parameters are currently being integrated in the development of Environmental Quality Criteria (EQC) for the Perth region. EQC play an important role in the management framework by providing the quantitative benchmarks for measuring success in achieving the environmental quality objectives. PLOOM has monitored a range of environmental parameters in the Perth Metropolitan area, including water quality, nutrient levels, water circulation and plume dilution, levels of metals and pesticides present in the marine environment, and the environmental health of benthic communities, in particular of temperate reef systems. During the PLOOM studies, a valuable tool was being developed to monitor outlet performance. Artificial reef structures (“periphyton collectors”) were placed in the plume trajectory. Here, periphyton is defined as: the microalgae (diatoms and microscopic filamentous forms), algal propagules, bacteria, microfauna and particulate material that are found in a mucous-like layer commonly coating seagrass leaves, and that initially colonise artificial surfaces. The advantage of periphyton collectors is that these largely remove the effects of natural variability, can be placed at any depth and distance from a potential nutrient source, provide an easy, cost effective measure of environmental impact, integrated over an extended period (one month), and produce tangible results which can be interpreted by the wider community, as well as legislative authorities and by outlet managers. In addition, outlet performance can be measured by means of these tools, and tested against accepted environmental criteria. Between 1995-2001, periphyton collectors, consisting of 15 × 15 cm PVC plates attached to moorings at fixed depths (2, 4 and 8 m), were deployed for one month during spring, summer and autumn, at increasing distance from the source (250 and 500 m distance to the north, east, west, and south, and at 1,000, 2,000, 4,000 m to the north and south only). After retrieval, the collectors were analysed for total biomass (g AFDW m−2), calcium carbonate content (% AFDW) and chlorophyll levels (chlorophyll a m−2). The results confirmed the predictions made by hydrodynamic modelling (e.g. Zic and Gondinoudis, 2002) and are in accordance with measured nutrient and chlorophyll a levels around the outlets, and demonstrated that the zone of influence was strongly determined by the prevailing currents (to the north), and largely restricted to surface layers (2-4 m depth). Both biomass and chlorophyll content proved reliable parameters, which have the potential to be used as Environmental Quality Criteria (EQC's) for the management of Perth's coastal waters. These EQC's were developed in collaboration with legislative authorities, as part of draft criteria, in accordance with national guidelines: ANZECC/ARMCANZ (2000) Australian and New Zealand Guidelines for Fresh and Marine Water Quality.

IntroductionPreconception carrier screening (PCS) identifies couples at risk of having children with recessive genetic conditions. New technologies have enabled affordable sequencing for multiple disorders simultaneously, including identifying carrier status for many recessive diseases. The aim of the study was to identify the most effective way of delivering PCS in Western Australia (WA) through the public health system.Methods and analysisThis is a multicentre cohort pilot study of 250 couples who have used PCS, conducted at three sites: (1) Genetic Services of Western Australia, (2) a private genetic counselling practice in Perth and (3) participating general practice group practices in the Busselton region of WA. The primary outcome of the pilot study was to evaluate the feasibility of implementing the comprehensive PCS programme in the WA healthcare system. Secondary outcome measures included evaluation of the psychosocial impact of couples, such as reproductive autonomy; identification of areas within the health system that had difficulties in implementing the programme and evaluation of tools developed during the study.Ethics and disseminationApproval was provided by the Women and Newborn Health Service Human Research Ethics Committee (HREC) at King Edward Memorial Hospital for Women (RGS0000000946) and the University of Western Australia (UWA) HREC (RA/4/20/4258). Participants may choose to withdraw at any time. Withdrawal will in no way affect participating couples' medical care. Study couples will be redirected to another participating health professional for consultation or counselling in the event of a health professional withdrawing. All evaluation data will be deidentified and stored in a password-protected database in UWA. In addition, all hard copy data collected will be kept in a locked cabinet within a secure building. All electronic data will be stored in a password-protected, backed-up location in the UWA Institutional Research Data Store. All evaluative results will be published as separate manuscripts, and selected results will be presented at conferences.

Lettuce plants showing symptoms of lettuce big-vein disease were collected from fields in the Perth Metropolitan region of southwest Australia. When root extracts from each plant were tested by polymerase chain reaction (PCR) using primers specific to the rDNA internal transcribed spacer (ITS) region of Olpidium brassicae and O. virulentus, only O. virulentus was detected in each of them. The nucleotide sequences of the complete rDNA ITS regions of isolates from five of the root samples and 10 isolates of O. virulentus from Europe and Japan showed 97.9 to 100% identities. However, with the six O. brassicae isolates, their identities were only 76.9 to 79.4%. On phylogenetic analysis of the complete rDNA-ITS region sequences of the five Australian isolates and 10 others, the Australian isolates fitted within two clades of O. virulentus (I and II), and within clade I into two of its four subclades (Ia and Id). Japanese isolates had greatest sequence diversity fitting into both clades and into all of clade I subclades except Ib, while European isolates were restricted to subclades Ib and Id. When the partial rDNA-ITS region sequences of two additional southwest Australian isolates, four from Europe, and four from the Americas were included in the analyses, the Australian isolates were within O. virulentus subclades Ia and Id, the European isolates within subclade Ic, and the American isolates within subclades Ia and Ib. These findings suggest that there may have been at least three separate introductions of O. virulentus into the isolated Australian continent since plant cultivation was introduced following its colonization by Europeans. They also have implications regarding numbers of different introductions to other isolated regions. Lettuce big-vein associated virus and Mirafiori lettuce big-vein virus were both detected when symptomatic lettuce leaf tissue samples corresponding to the root samples from southwest Australia were tested using virus-specific primers in reverse transcription–PCR, so presence of both viruses was associated with O. virulentus occurrence.

The Australian sea-lion, Neophoca cinerea, has a 17-18-month breeding cycle on islands off the west coast of Western Australia. Buller, North Fisherman and Beagle Is are the main pupping sites, with several very small colonies (n> 3) at the Abrolhos Is. The 4-5-month pupping seasons are synchronised at North Fisherman and Beagle Is, but the sea-lions from Buller I. breed one month later and those from the Abrolhos Is two months earlier. Pup production and pup mortality were highly variable between seasons over which observations were recorded: 129 pups were born at the main breeding sites in early 1988, the mortality in the first five months was 7.1%, whereas 181 pups were born in late 1989 of which 24.3% died. Pups remain in the vicinity of their natal islands for the first 4-5 months of life before leaving, perhaps on foraging trips, with their mothers. Most return to their natal island, although others haulout on islands up to 27 km away. Some male N. cinerea congregate in bachelor colonies on islands adjacent to the Perth metropolitan region during the non-breeding season and migrate up to 280 km north each breeding season. The status of the isolated, west-coast N. cinerea population is unknown. The current high level of human pressure on sea-lion terrestrial habitats and their food resources indicate a need for further monitoring of this species.

Density management diagram for eucalyptus stands controlled by dominant height. The present study aimed to elaborate Density Management Diagrams (DMD) for Eucalyptus grandis W. Hill. ex Maiden stands including the dominant height. Data were obtained from permanent plots installed in the Centro Oriental Riograndense region and the Porto Alegre Metropolitan area, both located in the state of Rio Grande do Sul. The models to describe the relationships between average volume, number of trees per hectare, mean diameter, and dominant height were assessed by the statistical criteria of coefficient of determination (R²), standard error of the estimate in percentage (Syx%), and graphical analysis of residuals. The developed DMD allows for a better control of stocks in the management of stands due to the strong relationship of dominant height with stand development site and forest yield.Keywords: Growth, Site index, Forest regulation, Yield.

Abstract High-resolution numerical simulations are conducted using the Coupled Ocean–Atmosphere Mesoscale Prediction System (COAMPS)1 with two different urban canopy parameterizations for a 23-day period in August 2005 for the New York City (NYC) metropolitan area. The control COAMPS simulations use the single-layer Weather Research and Forecasting (WRF) Urban Canopy Model (W-UCM) and sensitivity simulations use a multilayer urban parameterization based on Brown and Williams (BW-UCM). Both simulations use surface forcing from the WRF land surface model, Noah, and hourly sea surface temperature fields from the New York Harbor and Ocean Prediction System model hindcast. Mean statistics are computed for the 23-day period from 5 to 27 August (540-hourly observations) at five Meteorological Aviation Report stations for a nested 0.444-km horizontal resolution grid centered over the NYC metropolitan area. Both simulations show a cold mean urban canopy air temperature bias primarily due to an underestimation of nighttime temperatures. The mean bias is significantly reduced using the W-UCM (−0.10°C for W-UCM versus −0.82°C for BW-UCM) due to the development of a stronger nocturnal urban heat island (UHI; mean value of 2.2°C for the W-UCM versus 1.9°C for the BW-UCM). Results from a 24-h case study (12 August 2005) indicate that the W-UCM parameterization better maintains the UHI through increased nocturnal warming due to wall and road effects. The ground heat flux for the W-UCM is much larger during the daytime than for the BW-UCM (peak ∼300 versus 100 W m−2), effectively shifting the period of positive sensible flux later into the early evening. This helps to maintain the near-surface mixed layer at night in the W-UCM simulation and sustains the nocturnal UHI. In contrast, the BW-UCM simulation develops a strong nocturnal stable surface layer extending to approximately 50–75-m depth. Subsequently, the nocturnal BW-UCM wind speeds are a factor of 3–4 less than W-UCM with reduced nighttime turbulent kinetic energy (average &lt; 0.1 m2 s−2). For the densely urbanized area of Manhattan, BW-UCM winds show more dependence on urbanization than W-UCM. The decrease in urban wind speed is most prominent for BW-UCM both in the day- and nighttime over lower Manhattan, with the daytime decrease generally over the region of tallest building heights while the nighttime decrease is influenced by both building height as well as urban fraction. In contrast, the W-UCM winds show less horizontal variation over Manhattan, particularly during the daytime. These results stress the importance of properly characterizing the urban morphology in urban parameterizations at high resolutions to improve the model’s predictive capability.

Drought events have affected many regions of the world, having negative economic, environmental and social impacts. When accompanied by increasing water demands, these events can lead to water scarcity. Since droughts can significantly vary in each geographic area, several indices have been developed around the world. Hazard indexes are commonly used to predict meteorological, agricultural and hydrological droughts. These indexes intend to predict hazards, but they do not provide information on when and where deficits can have negative consequences. This study presents a new planning and decision-support tool for monitoring water scarcity situations in a given region. This tool, called the Water Scarcity Risk Index (W-ScaRI), is formed by two subindices, which are proposed to describe a hazard and its consequences. Each subindex was constructed using a group of indicators and indices selected from the technical literature or originally proposed in this work. The W-ScaRI was applied to the Rio de Janeiro Metropolitan Region (RJMR), supplied with water by the Guandu/Lajes/Acari system. The RJMR is one of the most densely populated regions in Brazil, located in an area that has no natural water bodies capable of meeting its supply needs. Therefore, the Guandu River, which, in fact, is formed by two discharge transpositions from the Paraíba do Sul River, is the main drinking water supply source for this region. The RJMR suffered the consequences of unexpected, prolonged droughts in the Southeast region in 2003 and 2014–2015, leading the local authorities to implement temporary emergency measures in the management system of Paraíba do Sul and Guandu Basins, avoiding water shortage but showing the urgent need for planning and management support tools to anticipate possible future problems. The results of the study show that the formulation of the W-ScaRI can represent the water scarcity risk in a relatively simple way and, at the same time, with adequate conceptual and methodological consistency.

Relations between the Ukrainian Church and Constantinople were difficult. This goes back as far as 988, when the Christianisation of the Rus created a strong alliance between Kiev and the Byzantine Empire. There were times when Constantinople had no influence over the Kiev Metropolis. During the Mongolian invasion in 1240, the Ukranian region was broken up and Kiev lost its power. The headquarters of the Kiev Metropolis were first moved to Wlodzimierz nad Klazma in 1299 and then to Moscow in1325. In 1458 the Metropolis of Kiev was divided into two; Kiev and Moscow, but Kiev still remained under the jurisdiction of the Patriarchate of Constantinople. Since that time, the orthodox hierarchs of Moscow no longer adhered to the title Bishop of Kiev and the whole of Rus and in 1588 the Patriarchate of Moscow was founded. In 1596 when the Union of Brest was formed, the orthodox church of the Polish Lithuanian Commonwealth was not liquidated. Instead it was formally revived in 1620 and in 1632 it was officially recognized by king Wladyslaw Waza. In 1686 the Metropolis of Kiev which until that time was under the Patriarchate of Constantinople was handed over to the jurisdiction of Moscow. It was tsarist diplomats that bribed the Ottoman Sultan of the time to force the Patriarchate to issue a decree giving Moscow jurisdiction over the Metropolis of Kiev. In the beginning of the 19th century, Kiev lost its Metropolitan status and became a regular diocese of the Russian Orthodox Church. Only in the beginning of the 20thcentury, during the time of the Ukrainian revolution were efforts made to create an independent Church of Ukraine. In 1919 the autocephaly was announced, but the Patriarchate of Constantinople did not recognize it. . The structure of this Church was soon to be liquidated and it was restored again after the second world war at the time when Hitler occupied the Ukraine. In 1992, after the dissolution of the Soviet Union, when Ukraine gained its independence, the Metropolitan of Kiev requested that the Orthodox Church of Ukraine becomes autocephalous but his request was rejected by the Patriarchate of Moscow. Until 2018 the Patriarchate of Kiev and the autocephalous Church remained unrecognized and thus considered schismatic. In 2018 the Ecumenical Patriarchate of Constantinople looked into the matter and on 5thJanuary 2019, the Orthodox Church of Ukraine received it’s tomos of autocephaly from Constantinople. The Patriarchate of Moscow opposed the decision of Constantinople and as a result refused to perform a common Eucharist with the new Church of Ukraine and with the Patriarchate of Constantinople.

The aim of this study was to carry out a taxonomic survey of epiphytic seaweeds that occur on reefs of Boa Viagem Beach, located in the metropolitan region of Recife – Pernambuco state, Brazil. The samplings were performed in the dry season (December 2009) and rainy season (April 2010) at intertidal reefs using 625 cm2 squares. Voucher specimens are deposited at the Herbarium of the Instituto de Botânica, São Paulo, Brazil (SP). A total of 48 taxa were recorded of which 20 were Chlorophyta, 27 Rhodophyta and one Heterokontophyta. The most representative orders were Ceramiales and Cladophorales, with 17 and 10 taxa respectively. Nine species are new additions to the flora of Pernambucan coast. Gelidium pusillum (Stackh.) Le Jol. 1863 and Chondracanthus saundersii C. W. Schneid. and C. E. Lane 2005 had the highest number of epiphytic macroalgae. The majority of species was collected in the rainy season and on wave-exposed sites.

Little is known of the breeding behaviour of the Forest Red-tailed Black Cockatoo Calyptorhynchus banksii naso (FRTBC), a large, iconic forest cockatoo, endemic to the south-west corner of Western Australia, currently listed as Vulnerable under the State Western Australian Wildlife Conservation Act and under the Commonwealth Environment Protection and Biodiversity Conservation Act. In this paper, we provide details of breeding behaviour of FRTBC based on observations throughout the year over 17 years, together with observations of diet and feeding behaviour over the same period. FRTBC are monogamous hollow-nesters. Breeding was recorded in all months, with peaks in autumn-winter (April– June) and spring (August–October), with few records in January and February. Breeding also varied between years, with little breeding in 1999, 2001 and 2008, but many observations in 2006 and 2009. Breeding occurred at times of fruiting of either of the principal feed trees, Jarrah Eucalyptus marginata or Marri Corymbia calophylla, so it does not depend solely on one or the other of these species. Courtship displays were noted at all times of the day, from before dawn at roost sites to dusk. In total, 205 breeding events were recorded, of which 69 (93%) of 72 nests had breeding confirmed on a second visit. Use of particular nest hollows varied considerably, with some used only once and some up to seven times. Only one egg is laid, which the female incubates for 29 to 31 days, before a nestling hatches weighing between 27 and 32 g. The female remains in the hollow during incubation and only leaves for a short period in the evening to be fed by the male, usually at dusk. The chicks are brooded for up to 10 days, after which the female leaves the nest between dawn and dusk. Pairs of birds appear to recognise each other by calls, not responding to calls by others in the area. Chicks only respond when the parent is heard. Chicks are fully feathered at 48 days. Fledgling success was estimated at 60%. Juveniles remain dependent on the adults 18 months to 2 years. Thirty-seven chicks were banded between 1997 and 2011. Juvenile-immature birds moved on average less than 3 km from their natal tree and older birds were observed moving up to 19 km. This suggests that FRTBC are generally sedentary. Immature birds took up to three times as long as their parents to open Jarrah or Marri nuts and eat the seeds. In recent years there has been an interesting change in foraging behaviour of birds in the northern Darling Range (adjacent to the Perth metropolitan area) with the FRTBC discovering and using a new food source, the introduced Cape Lilac Melia azedarach, and this species is of growing importance as food in the Perth region. In combination, the data on breeding biology and diet highlight the importance of identifying recruitment rates and food availability in managing populations of FRTBC.

209 Background: The WICaRE Program is a part of the cross sectional Patterns of Care Study–Breast and Prostate (PoC-BP) that sought to evaluate the patterns of BC care in the state WI and to identify areas for potential improvement in data collection and factors associated with variation in care. This study was to examine the geographic disparities in SM and the use of RT in female BC patients diagnosed in WI in 2004. Methods: The Wisconsin Cancer Reporting System (WCRS) receives reports from 130+ facilities. Information of patient (disease status, sociodemographic, treatment, county of residence) was obtained from cancer registries and supplemental data was reabstracted from medical charts across 66 counties. Geographic regions were counties grouped by WI Dept. of Health Services (DHS) as Northeastern (NE), Northern (N), Southeastern (SE), Southern (S), Western (W). Results: A total of 1037 cases were reported. 25% age 20-49, 49% age 50-69, and 28% age 70+; Caucasian had 82%, black 10% and others 8%. 34% had T1 stage, 9% T2, 4% T3+, and 53% TX-T0/unknown stage. 46% had reported mild comorbidity, 9% had moderate or severe comorbidity. Majority (73%) lived in the Metropolitan Statistical Area (MSA). 29% patients from NE region, 10% from N, 36% SE, 17% S and 8% W. Patients in the S and W had significantly lower % who received RT (46 and 48% respectively) than those in NE (61%), N (62%) and SE (63%), p=0.01; % mastectomy (MA) by regions were 43% (NE), 42% (N), 33% (SE), 47% (S) and 35% (W), p=0.009. Multivariate models adjusting for disease status, comorbidity, and sociodemographic factors showed that patients in MSA region were more likely to have RT compared to those in non-MSA (odds ratio, OR=1.66, 95%CI=1.14-2.40), but those in S were less likely than those in SE (OR=0.59, 95%CI=0.38-0.91). Patients in MSA had a decreased likelihood of undergoing mastectomy. NE (OR=1.6, 95%CI=1.08-2.29) and S (OR= 2.04, 95%CI=1.31-3.17) had significantly higher odds of having MA than those in SE. Conclusions: This study showed evidence of geographic disparity in medical care for BC patients in Wisconsin. Identifying factors mediating this disparity will help in developing appropriate treatment options and improving outcomes.

The Gravataí river situated in the metropolitan region of Porto Alegre has an area of approximately 2.020 km² and provides public water supply to about 500,000 inhabitants in 5 municipalities (latitude 29° 45'-30° 12' S; longitude 50° 27'-51° 12' W). The river basin has two regions with distinctive characteristics of occupation: the upper course shows intensive farming and the lower course presents urban and industrial uses. In this context, the aim of this study was to evaluate the water quality in the Gravataí River (RS, Brazil) by using physical, chemical and microbiological variables, and the water quality biological indices (WQBI) formulated for southern Brazilian rivers based on epilithic diatom communities as indicators. For comparison purposes, a local WQBI, called the Gravataí WQBI, was also used where species were given new saprobic values (s) and indicative values (vi) according to their occurrence and abundance in the river, using multivariate analytical techniques. The biological samples were taken every three months at six stations along the Gravataí River between September 2000 and August 2002. The results of the physical and chemical analyses of the water indicated a pollution gradient down the river, from the headwaters to the mouth, detected mainly by considering a significant decrease in the concentration of dissolved oxygen and turbidity, as well as a significant increase in BOD5, total nitrogen, ortho-phosphate and thermotolerant coliforms. Comparing the results obtained, differences were found regarding the predominant pollution levels as higher in the Gravataí WQBI, although both corroborated a tendency for the contamination gradient to increase from the headwaters to the mouth. Given the local anthropic changes, it is of great importance to continue the study of diatom species tolerance to organic pollution and eutrophication in different lotic systems of the region.

Abstract This work describes the seasonal and diurnal variations of downward longwave atmospheric irradiance (LW) at the surface in São Paulo, Brazil, using 5-min-averaged values of LW, air temperature, relative humidity, and solar radiation observed continuously and simultaneously from 1997 to 2006 on a micrometeorological platform, located at the top of a 4-story building. An objective procedure, including 2-step filtering and dome emission effect correction, was used to evaluate the quality of the 9-yr-long LW dataset. The comparison between LW values observed and yielded by the Surface Radiation Budget project shows spatial and temporal agreement, indicating that monthly and annual average values of LW observed in one point of São Paulo can be used as representative of the entire metropolitan region of São Paulo. The maximum monthly averaged value of the LW is observed during summer (389 ± 14 W m−2; January), and the minimum is observed during winter (332 ± 12 W m−2; July). The effective emissivity follows the LW and shows a maximum in summer (0.907 ± 0.032; January) and a minimum in winter (0.818 ± 0.029; June). The mean cloud effect, identified objectively by comparing the monthly averaged values of the LW during clear-sky days and all-sky conditions, intensified the monthly average LW by about 32.0 ± 3.5 W m−2 and the atmospheric effective emissivity by about 0.088 ± 0.024. In August, the driest month of the year in São Paulo, the diurnal evolution of the LW shows a minimum (325 ± 11 W m−2) at 0900 LT and a maximum (345 ± 12 W m−2) at 1800 LT, which lags behind (by 4 h) the maximum diurnal variation of the screen temperature. The diurnal evolution of effective emissivity shows a minimum (0.781 ± 0.027) during daytime and a maximum (0.842 ± 0.030) during nighttime. The diurnal evolution of all-sky condition and clear-sky day differences in the effective emissivity remain relatively constant (7% ± 1%), indicating that clouds do not change the emissivity diurnal pattern. The relationship between effective emissivity and screen air temperature and between effective emissivity and water vapor is complex. During the night, when the planetary boundary layer is shallower, the effective emissivity can be estimated by screen parameters. During the day, the relationship between effective emissivity and screen parameters varies from place to place and depends on the planetary boundary layer process. Because the empirical expressions do not contain enough information about the diurnal variation of the vertical stratification of air temperature and moisture in São Paulo, they are likely to fail in reproducing the diurnal variation of the surface emissivity. The most accurate way to estimate the LW for clear-sky conditions in São Paulo is to use an expression derived from a purely empirical approach.

Abstract. Atmospheric radiocarbon (14C) represents an important observational constraint on emissions of fossil-fuel derived carbon into the atmosphere due to the absence of 14C in fossil fuel reservoirs. The high sensitivity and precision that accelerator mass spectrometry (AMS) affords in atmospheric 14C analysis has greatly increased the potential for using such measurements to evaluate bottom-up emissions inventories of fossil fuel CO2 (CO2ff), as well as those for other co-emitted species. Here we use observations of 14CO2 and a series of primary hydrocarbons and combustion tracers from discrete air samples collected between June 2009 and September 2010 at the National Oceanic and Atmospheric Administration Boulder Atmospheric Observatory (BAO; Lat: 40.050° N, Lon: 105.004° W) to derive emission ratios of each species with respect to CO2ff. The BAO tower is situated at the boundary of the Denver metropolitan area to the south and a large industrial and agricultural region to the north and east, making it an ideal location to study the contrasting mix of emissions from the activities in each region. The species considered in this analysis are carbon monoxide (CO), methane (CH4), acetylene (C2H2), benzene (C6H6), and C3–C5 alkanes. We estimate emissions for a subset of these species by using the Vulcan high resolution CO2ff emission data product as a reference. We find that CO is overestimated in the 2008 National Emissions Inventory (NEI08) by a factor of ~2. A close evaluation of the inventory suggests that the ratio of CO emitted per unit fuel burned from on-road gasoline vehicles is likely over-estimated by a factor of 2.5. Using a wind-directional analysis of the data, we find enhanced concentrations of CH4, relative to CO2ff, in air influenced by emissions to the north and east of the BAO tower when compared to air influenced by emissions in the Denver metro region to the south. Along with enhanced CH4, the strongest enhancements of the C3–C5 alkanes are also found in the north and east wind sector, suggesting that both the alkane and CH4 enhancements are sourced from oil and gas fields located to the northeast, though it was not possible to rule out the contribution of non oil and gas CH4 sources.

Spatial accessibility by public transport is an important component of quality of life and an important factor undermining the development of rural areas. It is also a key element of a sustainable mobility system. The capitals of the powiat (county-level tier of administration in Poland) represent the level of the country’s urban hierarchy at which most-important public services are provided. Yet previously only rather few accessibility studies had been carried out, to consider how accessible the rural localities (villages) in the countries different province-regions might be. To fill that gap, the research presented in this paper sought to assess the 2019 level of accessibility via public transport to their own county cities (powiat capitals) that characterized no fewer than 14,271 rural localities in 6 of Poland’s 16 province-regions (i.e. Łódzkie, Kujawsko-Pomorskie, Małopolskie, Pomorskie, Warmińsko-Mazurskie and Zachodniopomorskie). The work also investigated factors shaping this accessibility, with a contribution thereby made to the ongoing debate as to the suitability of the current administrative division of Poland at county (powiat) level. The main findings and principal patterns as regards spatial accessibility could be summarised as follows: a. 1181 (8% of the studied) rural localities, with 215,000 inhabitants overall (or 4% of the rural population) had effectively no access to public transport at all; given that the nearest bus stop/railway station was beyond the acceptable distance of 4 km. b. Province-regions were found to differ markedly in terms of the measured accessibility, with Małopolskie province-region faring much better overall than the others (Figs. 1‑2, 10). c. Nevertheless, internal differentiation in levels of accessibility was greater within province-regions than between them. The best-observed accessibility characterised the environs of larger cities, and especially the Metropolitan Areas of Kraków (Małopolskie), Łódź (Łódzkie) and Gdańsk (Pomorskie), as well as the main transport corridors. Only poor accessibility characterised peripheral areas of most of the counties, while the worst accessibility of all applied in places where powiat-level peripheries were simultaneously peripheries of entire province-regions. d. An important factor determining accessibility was the type and size of rural locality. The larger the village, the better the accessibility (Fig. 19). This also linked up with the way in which size anyway correlated positively with distance to county city. This is to say that villages close to county cities had populations 30‑40% larger than those located on peripheries. e. Size of a county city also correlated positively with that city’s accessibility (Fig. 18). That was especially true of cities with 20,000 or fewer inhabitants. These have less-developed public transport and, as a consequence, far lower accessibility in their environs. Taken together, these patterns sustain a conclusion that the deregulation of public transport in Poland, which took place in the 1990s and ushered in a competitive market model, has had a serious impact on accessibility, ensuring further polarisation and growth in disparities. While better-developed areas (those in which population density is higher and villages larger) continue to furnish enough demand for commercially-viable public transport to be sustained, most of the peripheral, low-population areas are now at risk of transport-related exclusion. In most cases, there is poor public transport in such areas solely because some lines connecting cities or leading to certain tourist destinations remain in place and cross peripheries.

The article concerns the fate of Felicjan Karp’s family, one of the richest landowners of Samogitia (Lithuania) in the first two decades of the 20th century. After his father, he inherited approximately 40,163 hectares. The history of this family perfectly illustrates the changes that this social class has undergone in the past century. The end of their existence was the end of the landowner’s existence. The twilight of the Samogitian Karps took place quite quickly, for only a quarter of a century from July 28, 1914, the date of the outbreak of World War I to the Soviet invasion of the Republic of Lithuania on June 15, 1940. Over the course of these years - on a large scale two-fold - military operations, changes in the political and economic system, including agricultural reform initiated in the reborn Lithuanian state in 1922 and deportations to Siberia in 1940 brutally closed the last stable chapter in the life of Rekijów’s owners, definitively exterminating them after more than 348 years from the land of their ancestors. Relations between the Karp family and the Rekijów estate should be dated at least from September 21, 1592. In addition to the description of the family, it is also necessary to emphasize their significant economic and political importance in the inhabited region. These last two aspects gained momentum especially from the first years of the 19th century and were reflected until 1922. At that time, representatives of the Karp family jointly owned approximately 70,050 ha and provided the country with two provincial marshals (Vilnius, Kaunas) and two county marshals (Upita, Ponevezys). The author also presents their fate during World War II in the Siberian Gulag, during the amnesty under the Sikorski–Majski Agreement of July 30, 1941, joining the formed Polish Army in the USSR (August 14, 1941), the soldier’s journey through Kermine in Uzbekistan, Krasnovodsk, Caspian Sea, Khanaqin in Iraq, Palestine to the military camp near Tel-Aviv and then Egypt and the entire Italian campaign, that is the battles of Monte Cassino, Loreto and Ancona. After the war, leaving Italy to England (1946), followed by a short stay in Argentina and finally settling in Perth, Australia.

This article summarises a review of geographical studies on migration published in Poland after 1989, as also included in the Report of the Polish Academy of Sciences’ Migration Research Committee (Komitet Badań nad Migracjami) (Horolets et al., 2018). The work identifies around 750 bibliographical items from the years 1990‑2017, which it proves possible to assign to the categories of: the theory and methodology of geographical research into migration (including modelling and forecasting), internal migrations, external migrations (emigration and immigration), studies concerning foreign territories, research into migration historically (pre-WW2), and work concerning migration’s influence and impact on regional and local development. As is clear, no attention has been paid to issues of daily mobility (commutes to work or school), tourism (be that recreational, or related to business or pilgrimage), or to longer-term matters relating to ethnicity or multiculturalism. The review has also been supplemented to inclde work from the latest (2016‑2020) period. The studies that have been run prove to be of an empirical nature first and foremost, associated with the statistical and cartographic identification and description of observed phenomena and processes. This identification is most often based on secondary data from Statistics Poland – which deals with the ongoing processing of new registrations in the country, as well as deregistration. It seems that these data have been accepted more or less uncritically by most geographers, at least until recently. As the strands of research represented least abundantly are modelling, as well contributions to theory, this needs to be seen as marked regression in comparison with the situation in the 1970s – marking the zenith of Polish geographical work on migrations (or indeed more broadly on the processes of population and settlement). Set against the background of other disciplines, this denotes further a very large number of studies identified as geographical but not equating automatically to progress of a conceptual or theoretical nature. In contrast, a plus-point where the comparison is with typically statistical or demographic research, or partly even that of a sociological and economic nature, is a very good level of” feeling for/sensitivity to the space” (and hence familiarity with local factors), that allows us to avoid over-averaging or generalization in the direction of aggregate territories known to be too heterogeneous (not least the voivodeships into which Poland has long been divided at provincial – latterly provincial/regional – level). Avoided in this way is resort to over-generalised cognitive impacts in essence straying beyond the boundaries of geography into other disciplines. The main and most-original achievements of post-1989 geographical research can be seen to include:•multi-regional modelling of the dynamics to population change that takes account of the complexity of migration processes; •a particularly exhaustive and comprehensive reconnaissance and treatment of the migration-related specifics of the Opole-Silesia region;•work on the role played by migration (and mobility more broadly) in the development of suburban zones and metropolitan areas;•in-depth research into the linkage between migration and local or regional socioeconomic development;•a contribution to the classification, typology, delimitation and indication of migration, as well as the deployment of indicators in procedures of this type, in a context that is broader where scientific disciplines are concerned;•the empirical indication of population over- or under-estimates in different configurations of space as a reflection of unregistered migrations;•contributions to urbanisation theory including as regards the relations pertaining between migrations and the settlement system.

This paper deals with the relationship between the clustering potential and the actually created cluster structures in Poland. The authors compared the level of concentration of entities representing creative industries, expressed as the Location Quotient (LQ), with the locations of the creative clusters actually existing in Poland. The questions to which answers were sought were: (1) what is the geographical distribution of clustering potential where creative industries are concerned? (2) which gminas (units of local-government administration) are home to the entities forming the creative clusters?, and (3) are cluster structures really emerging in the areas offering the greatest clustering potential? To answer these questions, the authors conducted two analyses, of which the first led to a conclusion that – where the accepted interpretation of the LQ value is applied – only 1.9% of Poland’s gminas have conditions allowing for the building of creative specialisations, including via the development of creative clusters (where more stringent requirements are adopted, that share actually reduces further to 0.6%). Furthermore, the group in question shows a clearly-dominant role for gminas of Mazowieckie voivodship (province-region). In general, the distribution of creative entities across Poland is seen to be uneven, though it does correspond with the distribution of population through the country. Visible concentrations of the entities analysed were thus to be observed around the Metropolitan Areas of Warsaw, Kraków, Wrocław, Poznań, Łódź, the Tri-City (Gdańsk-Gdynia-Sopot) and Upper Silesia, as well as around Rybnik and Bielsko. A second result relates to the distribution of creative clusters, of which some 17 are to be noted. As of 2019, these each had between 4 and 66 members. Detailed analysis further confirms the very uneven geographical distribution, with Śląskie and in part also Małopolskie voivodships clearly dominant. Each of the remaining voivodeships have a maximum of two creative clusters. The two results obtained were then combined (Figs. 2 and 3), in line with an assumption that comparison of the clustering potential and the distribution of existing clusters would supply a positive and moderate correlation. In the event, no such result was obtained, with the coefficient for the correlation between the number of all surveyed entities in municipalities and the number of entities included in a cluster being: R=0.16. A similar result (of R=0.26) was obtained by examining the correlation between LQ and the numbers of entities forming clusters. This result shows that creative clusters are not established in Poland in the areas of the country offering the best conditions in terms of numbers of potential member entities. It follows that the creation of cluster structures is determined by other factors. These may include activity on the part of cluster facilitators, as well as the latter’s talent for acquiring new members for a cluster initiative, as well as the prospect of external funding being obtained. It is nevertheless endogenous potential that should be the driving force, given the favourable conditions it provides for economic specialisation to be pursued – as the basis upon which to build proper cluster structures.

Phaeomoniella chlamydospora (W. Gams, Crous. M.J. Wingfield & L. Mugnai) Crous & Gams (= Phaeoacremonium chlamydosporum) was isolated during the growing seasons of 2003-2004 from roots, trunks, and cordons of grapevines, including cvs. Cabernet Sauvignon, Merlot, Pinot noir, Thompson seedless, Ruby seedless and root stock 3309C, and Kober 5BB, from 10 locations in V, VI, VII, and metropolitan regions of Chile. P. chlamydospora was isolated from 82% of samples from vines 2 to 18 years old that showed decline symptoms in the field. Isolates were identified on the basis of a previous description (1) and internal transcribed spacer (ITS1-5.8S-ITS2) rDNA sequences identical to those of P. chlamydospora isolated from Vitis vinifera (culture CBS 22995, GenBank Accession No. AF 197973). P. chlamydospora is established as a member of the petri and esca disease complex and as a pathogen of grapevines (2,3). Pathogenicity tests were completed by injecting into the pith of 50 single-node, rooted cuttings of Pinot noir and 3309C, approximately 20 μl of a 106 conidia per ml suspension, obtained from four isolates from Chile and one from California. Ten control cuttings of Pinot noir and 3309C were injected with an equal volume of sterile distilled water. Twenty-four weeks after inoculations, all P. chlamydospora-inoculated cuttings exhibited dark streaking of the vascular tissue extending 40 to 45 mm from the point of inoculation. The vascular streaking observed in inoculated plants was identical to symptoms observed in declining vines in the vineyard. No symptoms were observed in the controls. P. chlamydospora was isolated from the region of vascular streaking in 85% of inoculated cuttings. P. chlamydospora was not isolated from the water-treated controls. The reisolated P. chlamydospora was verified with means of morphological characters and polymerase chain reaction amplification with the species-specific primers (3). P. chlamydospora is widespread and readily isolated from declining grapevines in Chile and other grape growing regions of the world. To our knowledge, this is the first report of P. chlamydospora from the cultivars cited above in Chile. References: (1) M. Groenewald et al. Mycol. Res. 105:651, 2001. (2) L. sparapano et al.

Abstract. The multidisciplinary project Prediction of Air Pollution in Latin America and the Caribbean (PAPILA) is dedicated to the development and implementation of an air quality analysis and forecasting system to assess pollution impacts on human health and economy. In this context, a comprehensive emission inventory for South America was developed on the basis of the existing data on the global dataset CAMS-GLOB-ANT v4.1 (developed by joining CEDS trends and EDGAR v4.3.2 historical data), enriching it with data derived from locally available emission inventories for Argentina, Chile, and Colombia. This work presents the results of the first joint effort of South American researchers and European colleagues to generate regional maps of emissions, together with a methodological approach to continue incorporating information into future versions of the dataset. This version of the PAPILA dataset includes CO, NOx, NMVOCs, NH3, and SO2 annual emissions from anthropogenic sources for the period 2014–2016, with a spatial resolution of 0.1∘ × 0.1∘ over a domain that covers 32–120∘ W and 34∘ N–58∘ S. The PAPILA dataset is presented as netCDF4 files and is available in an open-access data repository under a CC-BY 4 license: https://doi.org/10.17632/btf2mz4fhf.3 (Castesana et al., 2021). A comparative assessment of PAPILA–CAMS datasets was carried out for (i) the South American region, (ii) the countries with local data (Argentina, Colombia, and Chile), and (iii) downscaled emission maps for urban domains with different environmental and anthropogenic factors. Relevant differences were found at both country and urban levels for all the compounds analyzed. Among them, we found that when comparing PAPILA total emissions versus CAMS datasets at the national level, higher levels of NOx and considerably lower levels of the other species were obtained for Argentina, higher levels of SO2 and lower levels of CO and NOx for Colombia, and considerably higher levels of CO, NMVOCs, and SO2 for Chile. These discrepancies are mainly related to the representativeness of local practices in the local emission estimates, to the improvements made in the spatial distribution of the locally estimated emissions, or to both. Both datasets were evaluated against surface concentrations of CO and NOx by using them as input data to the WRF-Chem model for one of the analyzed domains, the metropolitan area of Buenos Aires, for summer and winter of 2015. PAPILA-based modeling results had a smaller bias for CO and NOx concentrations in winter while CAMS-based results for the same period tended to deliver an underestimation of these concentrations. Both inventories exhibited similar performances for CO in summer, while the PAPILA simulation outperformed CAMS for NOx concentrations. These results highlight the importance of refining global inventories with local data to obtain accurate results with high-resolution air quality models.

Climate change induced sea-level rise (SLR) is on its increase globally. Regionally the lowlands of China, Vietnam, Bangladesh, and islands of the Malaysian, Indonesian and Philippine archipelagos are among the world’s most threatened regions. Sea-level rise has major impacts on the ecosystems and society. It threatens coastal populations, economic activities, and fragile ecosystems as mangroves, coastal salt-marches and wetlands. This paper provides a summary of the current state of knowledge of sea level-rise and its effects on both human and natural ecosystems. The focus is on coastal urban areas and low lying deltas in South-East Asia and Vietnam, as one of the most threatened areas in the world. About 3 mm per year reflects the growing consensus on the average SLR worldwide. The trend speeds up during recent decades. The figures are subject to local, temporal and methodological variation. In Vietnam the average values of 3.3 mm per year during the 1993-2014 period are above the worldwide average. Although a basic conceptual understanding exists that the increasing global frequency of the strongest tropical cyclones is related with the increasing temperature and SLR, this relationship is insufficiently understood. Moreover the precise, complex environmental, economic, social, and health impacts are currently unclear. SLR, storms and changing precipitation patterns increase flood risks, in particular in urban areas. Part of the current scientific debate is on how urban agglomeration can be made more resilient to flood risks. Where originally mainly technical interventions dominated this discussion, it becomes increasingly clear that proactive special planning, flood defense, flood risk mitigation, flood preparation, and flood recovery are important, but costly instruments. Next to the main focus on SLR and its effects on resilience, the paper reviews main SLR associated impacts: Floods and inundation, salinization, shoreline change, and effects on mangroves and wetlands. The hazards of SLR related floods increase fastest in urban areas. This is related with both the increasing surface major cities are expected to occupy during the decades to come and the increasing coastal population. In particular Asia and its megacities in the southern part of the continent are increasingly at risk. The discussion points to complexity, inter-disciplinarity, and the related uncertainty, as core characteristics. An integrated combination of mitigation, adaptation and resilience measures is currently considered as the most indicated way to resist SLR today and in the near future.References Aerts J.C.J.H., Hassan A., Savenije H.H.G., Khan M.F., 2000.
