Understanding patterns of species richness is a major goal for ecologists, especially in space-limited habitats where many organisms live on top of others (epibiosis, e.g. by algae growing on gastropods in marine environments). We tested the hypotheses that species richness of epiflora on the gastropod Turbo torquatus would not differ between regions with similarly rich algal floras, and that epifloral richness would increase with increasing gastropod size. Macroalgal floras of Hamelin Bay (HB), Marmion (M), Jurien Bay (JB) and Kalbarri (K), Western Australia, ranged from ∼20 to 40 species reef–1 (JB = HB = M ≥ K). Epiflora on small T. torquatus (shell area <150 cm2) did not differ among regions but epifloral richness increased with increasing basibiont size. Large T. torquatus (>150 cm2) were only found in Hamelin Bay and Marmion, where epifloral richness differed substantially. Epifloral richness was positively related to basibiont size in Marmion but not in Hamelin Bay. However, densities of patellid limpets on large T. torquatus were ∼4× higher in Hamelin Bay than in Marmion, implying that limpet grazing suppresses epifloral richness. Epifloral richness on turbinids is not simply associated with regional species pools or gastropod size; rather, biological interactions at the scale of individual basibionts apparently govern broad scale patterns of epibiosis.

Fragum erugatum populations were sampled over two consecutive years in Hamelin Pool, Lharidon Bight and Freycinet Harbour, which are representative of the hypersaline and metahaline regimes of Shark Bay. F. erugatum was widely distributed infratidally between 1.2 m and 6.5 m depth. Dense aggregations of zooxanthellae were present in mantle and gill tissue. Shell shape of the population from Hamelin Pool differs from that of the Lharidon Bight, Freycinet Harbour and Dampier Archipelago populations. F. erugatum was found to be a synchronous hermaphrodite. Settlements of juveniles, and modality of size distributions, indicate a single annual spawning. Production estimates of dry flesh and shell (CaCO3 inclusive) were much lower in Hamelin Pool than in Lharidon Bight, largely because of the lower density of F. erugatum recorded in Hamelin Pool. Although shells are washed ashore continuously, large-scale deposition of the accumulated infratidal coquinas, largely composed of F. erugatum shells, probably occurs periodically in major storm events, thereby forming the Hamelin Coquina.

ABSTRACT Stromatolites, organosedimentary structures formed by microbial activity, are found throughout the geological record and are important markers of biological history. More conspicuous in the past, stromatolites occur today in a few shallow marine environments, including Hamelin Pool in Shark Bay, Western Australia. Hamelin Pool stromatolites often have been considered contemporary analogs to ancient stromatolites, yet little is known about the microbial communities that build them. We used DNA-based molecular phylogenetic methods that do not require cultivation to study the microbial diversity of an irregular stromatolite and of the surface and interior of a domal stromatolite. To identify the constituents of the stromatolite communities, small subunit rRNA genes were amplified by PCR from community genomic DNA with universal primers, cloned, sequenced, and compared to known rRNA genes. The communities were highly diverse and novel. The average sequence identity of Hamelin Pool sequences compared to the >200,000 known rRNA sequences was only ∼92%. Clone libraries were ∼90% bacterial and ∼10% archaeal, and eucaryotic rRNA genes were not detected in the libraries. The most abundant sequences were representative of novel proteobacteria (∼28%), planctomycetes (∼17%), and actinobacteria (∼14%). Sequences representative of cyanobacteria, long considered to dominate these communities, comprised <5% of clones. Approximately 10% of the sequences were most closely related to those of α-proteobacterial anoxygenic phototrophs. These results provide a framework for understanding the kinds of organisms that build contemporary stromatolites, their ecology, and their relevance to stromatolites preserved in the geological record.

The application of modern methods of time-series analysis to a record of sea-level variation at Flint Cliff, Hamelin Pool, between October 1983 and April 1985, shows that astronomical tides account for only one of the following five key components of the record: a seasonal oceanic cycle; a short-term irregular cycle; the complex astronomical tidal system in the Pool; isolated major events; and less marked variations probably reflecting wind stress, still able to defeat the astronomical tide in the short-term. We have compared the inundation record with precisely surveyed elevation ranges of various microbial communities. The dominance of a seasonal cycle is the fundamental determinant of variation in the duration of immersion and exposure determining the littoral zonation of microbial mats in Hamelin Pool. The astronomical tide is not the major cause of this variation. The microbial communities fall into three zones. In Zone 3, the microbialite-forming colloform mat is virtually never exposed. In Zone 2, smooth, reticulate and mamillate mats colonise the lower littoral environment. Here, many of the exposed microbialites have been stranded by the falling sea level, and are colonised by intermittently submerged microbial communities that modify the stranded lithified microbialites. Zone 1 is inundated only under exceptional circumstances and microbial communities are ephemeral.

The zooplankton of Shark Bay, Western Australia, shows an unusual pattern of abundance, with an initial increase from the ocean to the central bay, and a decrease of four orders of magnitude into the hypersaline region. The daytime zooplankton abundance in Hamelin Pool, at a salinity of >60 mg 1-1, is of a similar magnitude to that of the deep sea, and 100-fold below typical surface oceanic values. Night abundances are higher, but still well below surface oceanic values. The diverse oceanic community of net phytoplankton and zooplankton is replaced at intermediate salinities by a less diverse bay community, dominated by diatoms and several small copepods. At high salinities, the phytoplankton are mostly dinoflagellates and the zooplankton are mainly demersal forms. The abundance patterns for individual species can be attributed to intolerance of high salinity, although the pattern of total abun- dance is apparently due to extreme nutrient limitation in the hypersaline waters.

Several halophilic archaea belonging to the genus Halococcus were isolated from stromatolites from Hamelin Pool, Shark Bay, Western Australia, collected during field trips in 1996 and 2002. This is the first incidence of halophilic archaea being isolated from this environment. Stromatolites are biosedimentary structures that have been formed throughout the earth's evolutionary history and have been preserved in the geological record for over 3 billion years. The stromatolites from Hamelin Pool, Western Australia, are the only known example of extant stromatolites forming in hypersaline coastal environments. Based on their 16S rRNA gene sequences and morphology, the isolates belong to the genus Halococcus. Strain 100NA1, isolated from stromatolites collected in 2002, was closely related to strain 100A6T that was isolated from the stromatolites collected in 1996, with a DNA–DNA hybridization value of 94±8 %. DNA–DNA hybridization values of strain 100A6T with Halococcus morrhuae NRC 16008 and Halococcus saccharolyticus ATCC 49257T were 17±6 and 11±7 %, respectively. The DNA G+C content of strain 100A6T was 60.5 mol% (T m). The main polar lipid was S-DGA-1, a sulphated glycolipid that has been detected in all strains of the genus Halococcus. Whole-cell protein profiles, enzyme composition and utilization of various carbon sources were distinct from those of all previously characterized Halococcus species. The recognition of this strain as representing a novel species within the genus Halococcus is justified, and the name Halococcus hamelinensis sp. nov. is proposed. The type strain is 100A6T (=JCM 12892T=ACM 5227T).

Stable isotopes of oxygen and hydrogen are used here with salinity data in geochemical and mass-balance models to decipher the proportion of different sources of water in two hypersaline estuaries that vary in size and hydrologic condition. Shark Bay, located on the mid-western coast of Australia, is hypersaline year round and has an arid climate. Florida Bay, located in the south-eastern United States, is seasonally hypersaline and has a subtropical climate. The water budget in both bays can be explained by evaporation of seawater, with seasonal inputs of surface-water runoff and precipitation. In Shark Bay, discharge from the Wooramel River associated with a recent major flood was detected in the relationship between the stable isotopic composition and salinity of surface waters near the mouth of the river, despite the persistence of hypersalinity. The volume of water equal to one pool volume replenished Hamelin Pool (a hypersaline water body located at the southern end of eastern Shark Bay that supports living stromatolites) once every 6–12 months. The eastern portion of Florida Bay received a greater proportion of freshwater from overland flow (70–80%) than did the western portion where rainfall was the dominant source of freshwater.

Differences in the diversity of fish species between granite and limestone reefs, as well as high- and low-relief limestone reefs, were investigated at Hamelin Bay, south-western Australia. It was found that there were significant differences in the presence and abundance of fish species between granite reefs and limestone reefs. Granite reefs were characterized by greater numbers of Coris auricularis (western king wrasse) and Parma mccullochi (common scalyfin), whereas limestone reefs had greater numbers of the fish species Odax cyanomelas (herring cale), Pempheris klunzingeri (rough bullseye) and Kyphosus sydneyanus (common buffalo bream). A significant difference in fish diversity was also found between high-relief and low-relief limestone reefs in the same area. More species were found on the high-relief reefs than low-relief reefs. Complementing differences in fish assemblages, significant differences were found in algal assemblages from the different habitats. This was mainly owing to a dominance of Ecklonia radiata on low-relief limestone reefs. Ecklonia radiata was less dominant on granite reefs and on high-relief limestone reefs, where there was a lower overall algal biomass and a higher total number of species.

The thick-billed grasswren (Amytornis textilis) has a disjunct distribution in the Shark Bay region, with one population confined to Peron Peninsula and the other further inland on Woodleigh Station and the north-eastern corner of Hamelin Station. Grasswrens were found in several vegetation types, including acacia shrublands, Triodia spinifex and the dense vegetation in drainage depressions. Vegetation characteristics that appeared important determinants of grasswren presence were recumbent acacias and low shrubs within the 0–1-m height category, and shrub clumps of high foliage density. These shrub clumps comprised climbers and recumbent low shrubs with interwoven branches, often in association with other plant species. Habitats with this shrub structure may provide the grasswren with ideal nesting sites. The possible effects of grazing and fire on this shrub structure are discussed.

Seasonal variations in water and sodium turnover of resident populations of free-ranging Sericornis frontalis were measured at three sites in Western Australia ranging from arid, through semi-arid to mesic environments. Scrubwrens at all three sites maintained water and sodium balance despite the wide variation in environment. During winter at semi-arid Eyre, however, scrubwrens had a greatly increased dietary sodium intake resulting from the deposition of airborne oceanic salt over the coastal dunes. Scrubwrens at arid Hamelin had significantly lower water turnover rates (e.g. 1.3 ml 10 g-'d-') than those at Eyre and mesic Rockingham during hot, dry periods. The highest rates of water turnover were recorded at Rockingham during wet winters. We discuss the ecological implications of these results. In laboratory studies, scrubwrens from arid regions consumed NaCl solutions of up to 0.8 mol l-', compared with a maximum of only 0.6 ml l-' by scrubwrens from semi-arid and mesic regions. Shark Bay scrubwrens also had a much greater renal-concentrating ability which may be partially accounted for by the larger proportion of medullary tissue in the kidneys of these birds.

Since its detection on ornamental pines in St. John's, Newfoundland, Canada, in 1979 (3), the European race causing Scleroderris canker (Gremmeniella abietina (Lagerb.) Morelet) has been detected throughout the Avalon Peninsula at the eastern end of the province. A quarantine was established on the Avalon Peninsula in 1980 to reduce the risk of introducing the disease to the natural red pine (Pinus resinosa Aiton) stands on the remainder of the island. Scots, red, and jack pines were examined at 34 locations in Newfoundland in 1998 and 1999. Infected trees were detected at four locations outside the quarantine zone. In the fall of 1998, the disease was found in plantations at three locations outside the quarantine zone: on Scots pine (P. sylvestris L.) at Bonavista and Catalina (≈135 km north-northeast of the quarantine) and on jack pine (P. banksiana Lamb.) and Scots pine at Sunnyside on Trinity Bay (≈45 km northwest of the quarantine). In 1999, the disease was detected at a fourth location on planted Scots pine in Come By Chance, near the Sunnyside location. Cultures of the pathogen were recovered from branch samples collected at each location and submitted for race determination at the Laurentian Forestry Centre, Sainte-Foy, QB. All isolates were determined based on the polymerase chain reaction diagnostic technique (1) to be the European race of G. abietina. This is a significant range extension from that reported by Laflamme et al. (2). The infected trees originated from the former Back River tree nursery at Salmonier Line that provided planting stock for a provincial reforestation program between 1937 and 1952. Evidence suggests that this nursery was the source of infected stock for plantations at nine locations within the Avalon Peninsula quarantine zone and the four new locations detected during the 1998 and 1999 surveys. This is similar to the pattern described for other nurseries in eastern Canada and the United States (2). The presence of the European race of G. abietina outside of the Avalon Peninsula increases the risk that the disease will become established in the rare natural red pine stands on the rest of the island of Newfoundland.

AbstractThe carrot psyllid Trioza apicalis Förster 1848 is a carrot pest in Europe that can cause serious damages in case of massive occurrence. Damages up to a total loss of yield have been reported from Scandinavian countries but also from Switzerland. The action threshold to control the pest with chemical pesticides is 0.2 T. apicalis per day and trap caught by sticky traps. We investigated the number of T. apicalis with sticky traps on carrot fields of the study regions Lüneburg/Uelzen and Hameln/Bad Pyrmont in Germany, during the period 2017–2020. The number of T. apicalis caught was generally very low in both study regions. On several fields in successive weeks almost no individuals were found in the study region Hameln/Bad Pyrmont. In Lüneburg/Uelzen was at least one field each year where the number of carrot psyllid was clearly higher than in all other fields and exceeded the threshold level. Surprisingly on carrot fields in close proximity to carrot fields from the previous year, the T. apicalis numbers were only slightly increased. Nonetheless, no loss of yield was reported for any of the fields in the four years of the study, although the generally defined threshold has been exceeded on many of the investigated carrot fields.

ABSTRACT The complete genome sequence of Methanohalophilus halophilus DSM 3094T, a member of the Methanosarcinaceae family and the Methanosarcianales order, consists of 2,022,959 bp in one contig and contains 2,137 predicted genes. The genome is consistent with a halophilic methylotrophic anaerobic lifestyle, including the methylotrophic and CO2-H2 methanogensis pathways.

The Linear Elamite writing system was used in the late 3rd millennium in ancient Iran.The underlying language is supposed to be Elamite – an isolate language otherwise known from cuneiform sources. 40 to 60% of the Elamite words and morphemes are decoded.In early 2016, about ten new inscriptions and fragments were presented at the University of Hamedan, Iran. They are now in the Mahboubian Gallery. Some of these new texts are the longest ones ever found, depicting up to 200 signs.In the past months, the Deciphering Crew at the Institut für Sprachwissenschaft, Universität Bern, has made drawings of the so far unpublished inscriptions and compiled a sign catalogue.Preliminary results show that fragments from Gonur and Altyn Depe formerly tagged as “Linear Elamite” do not belong to the Linear Elamite text corpus.The Deciphering Project is hoping to collaborate with scholars of different fields. The web page http://elamicon.org is an open source project.

Background: Acceptance and commitment therapy is a third generation behavior therapy mainly used in treatment of mood and anxiety disorders. The main goal of this study was to investigate the effectiveness of acceptance and commitment group therapy on anxiety, depression and Rumination in mothers of children with special needs. Materials and Methods: The statistical society included mothers of children with special needs in Hamedan city. In this semi-experimental design, by using convenience sampling;18mothers were selected and they were divided into two groups of intervention and control randomly. Mental evaluation included a clinical interview (based on DSM-V), a clinical psychologist conducted Beck Depression Inventory (BDI-II), Beck Anxiety Inventory (BAI) and Rumination Response Scale (RRS). Depression, anxiety and rumination Scales were assessed at three stages: prior and after first intervention session and three weeks after the intervention sessions. Data were subjected to descriptive statistics and the analysis with a mixed ANOVA design. Results: Findings showed significant decrease in scales of Depression, Anxiety and Rumination and in post-test and follow up after Acceptance and commitment therapy intervention. Thus, group treatment based on the acceptance and commitment therapy caused significant changes in the treatment of anxiety, depression and rumination in mothers of children with special needs. Conclusion: The result of this study highlights the efficient role of acceptance and commitment group therapy on mothers of children with special needs and it introduces new horizons in clinical interventions.
