Abstract:
Superficial dermatophyte infections, commonly known as tineas, are the most prevalent fungal ailment and are increasing in incidence, leading to an interest in alternative treatments. Many floral honeys possess antimicrobial activity due to high sugar, low pH, and the production of hydrogen peroxide (H2O2) from the activity of the bee-derived enzyme glucose oxidase. Australian jarrah (Eucalyptus marginata) honey produces particularly high levels of H2O2 and has been found to be potently antifungal. This study characterized the activity of jarrah honey on fungal dermatophyte species. Jarrah honey inhibited dermatophytes with minimum inhibitory concentrations (MICs) of 1.5–3.5% (w/v), which increased to ≥25% (w/v) when catalase was added. Microscopic analysis found jarrah honey inhibited the germination of Trichophyton rubrum conidia and scanning electron microscopy of mature T. rubrum hyphae after honey treatment revealed bulging and collapsed regions. When treated hyphae were stained using REDOX fluorophores these did not detect any internal oxidative stress, suggesting jarrah honey acts largely on the hyphal surface. Although H2O2 appears critical for the antifungal activity of jarrah honey and its action on fungal cells, these effects persisted when H2O2 was eliminated and could not be replicated using synthetic honey spiked with H2O2, indicating jarrah honey contains agents that augment antifungal activity.

Abstract:
Rufous treecreepers (Climacteris rufa) are common in southern jarrah forests of Western Australia, but nothing has been recorded of their ecology in the region. I investigated the foraging and nesting ecology of the species in the southern jarrah forests from January 1994 to April 1996. Rufous treecreepers foraged exclusively on two eucalypt species, jarrah and marri, and foraged on trees that were significantly larger and taller than random. Foraging on the ground, logs and fallen trees was relatively infrequent. Nest hollows were also located exclusively in jarrah and marri trees that were significantly larger and taller than random. The important foraging and nesting resources for the species in the southern jarrah forest appear to be large mature and overmature eucalypts. Anthropogenic impacts in the region, primarily logging, should aim to retain these resources in affected areas to improve the survival prospects of the species. When compared with studies in wandoo woodlands, the results of the present study indicate that the conservation of ground-layer habitat is likely to be of less importance in the jarrah forest. These habitat differences indicate that site-specific information is critical if the management and conservation of individual species is to be effective.

Abstract:
Abstract The May 2021 Palestinian demonstrations in Shaikh Jarrah and Damascus Gate in occupied East Jerusalem and elsewhere in Arab towns inside Israel mark a dramatic shift in Israeli Palestinian conflict. These events in al Quds (Jerusalem) are directly linked to the Israeli policy of expelling more Palestinians from the borderland zone. In effect, such policy is used to control the most important geo-political space– the Shaikh Jarrah neighbourhood. In so doing, it imposes sovereignty over the Damascus Gate and its steps. The ongoing Israeli policy of imposing full control over the Shaikh Jarrah neighbourhood would mean challenging the historical role of diplomatic missions, international consulates and organizations, which represent many countries in the region. Based on ongoing research and interviews in East Jerusalem, this special essay argues that the Shaikh Jarrah protests are another manifestation of the ongoing struggle over control and sovereignty in the Old City and occupied East Jerusalem. It shows how the Shaikh Jarrah demonstrations display a unique picture of the conflict over borderland and geopolitics in al Quds.

Abstract:
Jarrah (Eucalyptus marginata) is a dominant forest tree endemic to the southwest of Western Australia. Its honey is appreciated for its highly desirable taste, golden colour, slow crystallisation, and high levels of bioactivity, which have placed Jarrah in the premium product range. However, whilst customers are willing to pay a high price for this natural product, there is currently no standard method for its authentication. As honey is naturally sourced from flower nectar, a novel route of authentication is to identify the nectar signature within the honey. This study reports on a high-performance thin layer chromatography (HPTLC)-based authentication system which allows the tracing of six key marker compounds present in Jarrah flower nectar and Jarrah honey. Four of these markers have been confirmed to be epigallocatechin, lumichrome, taxifolin and o-anisic acid with two (Rf 0.22 and 0.41) still chemically unidentified. To assist with the characterisation of Jarrah honey, a range of physicochemical tests following Codex Alimentarius guidelines were carried out. A blend of authenticated Jarrah honey samples was used to define the properties of this honey type. The blend was found to have a pH of 4.95, an electric conductivity of 1.31 mS/cm and a moisture content of 16.8%. Its water-insoluble content was 0.04%, its free acidity 19 milli-equivalents acid/kg and its diastase content 13.2 (DN). It also contains fructose (42.5%), glucose (20.8%), maltose (1.9%) and sucrose (<0.5%). The HPTLC-based authentication system proposed in this study has been demonstrated to be a useful tool for identifying Jarrah honey and might also act as a template for the authentication of other honey types.

Abstract:
In rice (Oryza sativa L.) OsAMT1.1 is the most active and / or most N-responsive gene responsible for high-affinity NH4+ transport (HATS) activity. We measured 13NH4+ influx and plant biomass in transgenic overexpression lines and two wild type cultivars of rice, Jarrah and Taipei, with one or more copies of OsAMT1.1. 13NH4+ influx was higher for the overexpression lines of Jarrah line when grown at 10 µm external NH4+ concentration, but not for the overexpression lines of Taipei. For seedlings grown at 2 mm external NH4+ concentration Jarrah lines 77-1 and 75-4 showed an increased influx; however, two overexpression lines of Taipei showed reduced influx rates. The biomasses of the transgenic lines grown at low and high external NH4+ concentrations were either reduced or showed no statistically significant differences compared with wild type lines. While 13NH4+ influx into roots of Jarrah line 75-4 grown at 10 µm external NH4+ concentration was significantly higher than in wild type, measurements of 13NH efflux revealed no differences, and thus net uptake of NH4+ was higher in this overexpression line.

Full text
Abstract:
Knowledge of the ecology of the chuditch (Dasyurus geoffroii) is largely restricted to its distribution in mesic jarrah forests. There is a need for information regarding its ecology in semiarid zones where rainfall and consequently productivity are lower than mesic forests. Given that spatial requirements are strongly influenced by resource availability, it was expected that the chuditch in the semiarid zone would be present at lower densities and would have larger core home ranges (defined by daytime refuges) than those in the jarrah forests. The diet was also investigated by examining the contents of scats. Chuditch at Forrestania were trapped and six individuals were radio-tracked. The population density was one-third that of the lowest estimate reported from the jarrah forest and core home-range estimates were substantially larger, particularly for males. The diet included mammals, birds, reptiles, invertebrates, plants and rubbish, which was consistent with it being a generalist predator. Chuditch did have greater spatial requirements than in the jarrah forest, therefore different management regimes may be needed for populations occurring in the semiarid zone.

Abstract:
Jarrah (Eucalyptus marginata Donn ex Sm.) plants, like many other eucalypts, can form symbiotic associations with both arbuscular mycorrhizal (AM) and ectomycorrhizal (ECM) fungi. To study this tripartite relationship we developed a novel nurse-pot system to allow us to investigate the extent and temporal colonisation dynamics of jarrah by two AM species (Rhizophagus irregularis (Błaszk., Wubet, Renker & Buscot) C. Walker & A. Schüßler comb. nov. and Scutellospora calospora Nicol. & Gerd.) and two putative ECM species (Austroboletus occidentalis Watling & N.M. Greg. and Scleroderma sp.) and their potential effects on jarrah growth and nutrition. Our nurse-pot system, using jarrah as both the nurse plant and test plant, was developed to establish extraradical hyphal networks of both AM and ECM fungi that act as single or dual inoculum for test plants. Mycorrhizal colonisation was described and quantified, and growth and nutritional effects measured and analysed. Mycorrhizal colonisation increased with time for the test seedlings exposed to hyphae networks from S. calospora and Scleroderma sp. The nurse-pot system was effective at initiating colonisation of functioning AM or (putative) ECM systems separately but the ECM symbiosis was inhibited where a dual AM + ECM inoculum (R. irregularis and Scleroderma sp.) was present. The presence of S. calospora, A. occidentalis and Scleroderma sp. individually significantly increased the shoot biomass of seedlings compared with non-mycorrhizal controls. The two AM isolates had different physiological effects on jarrah plants. S. calospora improved growth and micronutrient uptake of jarrah seedlings whereas no positive response was observed with R. irregularis. In addition, as an interesting observation, the non-responsive AM fungus R. irregularis suppressed the ECM symbiosis in dually inoculated plants where ECM structures, positive growth response and nutritional effects were absent. When inoculated individually, ECM isolates dominated the growth response and uptake of P and other nutrients in this dual symbiotic plant. Despite the positive growth response in the A. occidentalis treatment, ECM structures were not observed in either nurse or test seedlings. From the effects of A. occidentalis on jarrah we hypothesise that this fungus forms a functional mycorrhizal-type partnership even without forming archetypal structures in and on the root.

Abstract:
Field experiments were established on seven sites in the northern jarrah forest of south-west Western Australia to test the effect of (i) overstorey, site, seedbed, seeding date and seed harvesting by vertebrates and invertebrates on emergence, (ii) overstorey, site. seedbed, application of fertiliser and grazing on mortality, and (iii) overstorey, site and application of fertiliser on growth of Eucalyptus marginata seedlings. Rainfall, soil temperature, soil water deficits. leaf water potential and photosynthetically active radiation (PAR) were monitored over two years. Seed harvesting by small vertebrates substantially reduced emergence, whereas invertebrates only slightly reduced emergence. Ninety per cent of seed was removed within one day where it was on the soil surface and in the open, whereas seed removal was insignificant when the seed was covered by soil. Vertebrates harvested seed more effectively when the understorey and litter were removed and the seed was more visible on the soil surface. Seed harvesting by small vertebrates had less impact on a site where there had been bauxite mining possibly because the surrounding area was being revegetated with large numbers of seed and the area afforded poor cover for vertebrates. Emergence was less where the overstorey was removed compared to where it was retained and on the bauxite pit compared to the forest sites. There was no difference in emergence between the low and high quality forest sites and so the emergence phase could not explain the variation in abundance of E. marginata trees on the different quality sites. Seedlings on sites with the overstorey removed experienced significantly higher soil temperatures for nine months of the year (of up to 6°C)/ smaller soil and leaf water deficits during the dry season (minimum predawn leaf water potentials of -0.5 MPa compared to -1.6 MPa), and higher intensities of PAR (maximum values of 1900 [umol m-2 s- compared to 900 1 /jmol m-2 s-1 compared to seedlings on sites with the overstorey retained. Mortality of E. marglnata seedlings was greater on sites where the overstorey was retained compared to where the overstorey was removed, on low quality sites than high quality sites and on undisturbed and lightly disturbed seedbeds compared to heavily disturbed seedbeds. Neither fertilising nor grazing by vertebrates had a statistically significant effect on mortality. Most of the mortality occurred as water deficits developed in late spring and summer and the major cause of mortality was attributed to water deficits. Some mortality occurred prior to this and was probably caused by pathogenic fungi. Mortality of E. marginata seedlings in the northern jarrah forest of Western Australia can be minimised by reducing the density of the overstorey and by seeding into a seedbed which has had litter and ground cover removed and the soil disturbed. Shoot dry weight was eight times greater, leaf area was more than 20 times and photosynthesis was two to 10 times greater on sites with the overstorey removed. Fertilising increased shoot dry weight by a factor of two. For sites with the overstorey removed, seedlings on the high quality site achieved six times the shoot dry weight of those on the bauxite pit and three times the shoot dry weight of those on the low quality site. Shoot dry weight was strongly related to leaf area index, independent of the effects of overstorey, site quality and fertiliser. Leaf growth commenced in spring when soil temperature at 40 cm reached 17°C, it was then primarily limited by water deficits until late autumn when soil temperature fell below 15°C, at which point leaf growth had nearly stopped. Leaf growth and photosynthesis both decreased as water deficits developed over the dry Seedlings season. on the site with the overstorey removed had higher rates of photosynthesis and greater photosynthetic capacity than those on the site with the overstorey retained. To understand the effects of soil temperature, shade by an overstorey and water deficits on seedling growth, a series of controlled environment studies was undertaken where each factor alone was studied. The effect of soil temperature on the growth of E. marginata seedlings was studied in the first glasshouse experiment. Soil temperature had a significant effect on the growth of all plant parts except the cotyledons. Total plant growth and shoot growth were maximal at a soil temperature of 30°C, but root growth had a slightly lower optimum such that the root:shoot ratio was highest at 20°C. Roots grown at 15°C had about 30% less length per unit of DW than those grown at 20 - 35°C. The effect of shade on plant growth, dry weight partitioning and photosynthetic response to light of E. marginata seedlings was studied in the second glasshouse experiment. Plant dry weight and that of all plant parts declined in response to shade, as did the root:shoot ratio. Plant leaf area was less for plants grown under no shade than for plants grown under shade. Specific leaf area increased with shade. Seedlings grown under no shade had a higher light saturated rate of photosynthesis, a higher light compensation point and a higher light saturation level than seedlings grown under 70% shade. E. marginata seedlings responded to shade in a very similar way to other eucalypts which naturally regenerate below an overstorey. Plant dry weight and leaf dry weight were strongly related, independent of shade, whereas the relationship between plant dry weight and plant leaf area was dependent on the level of shade. Therefore, leaf dry weight may be a better predictor of biomass production in forest stands where shade is likely to be a significant factor affecting growth. Leaf growth, net rate of leaf photosynthesis and tissue water relations of shoots of E. marginata seedlings was studied over the course of a soil drying and rewatering cycle in the third glasshouse experiment to determine the effect of water deficits on these parameters. The relationship between midday photosynthesis and predawn leaf water potential showed that photosynthesis of E. marginata seedlings is very sensitive to water deficits. Midday photosynthesis declined to 40% of that of well hydrated seedlings at a predawn leaf water potential of -1 MPa and reached zero at -2.2 MPa. Photosynthesis recovered rapidly following rewatering and was nearly completely recovered by the second day after rewatering. The rate of leaf growth decreased linearly with predawn leaf water potential to reach zero at -1.5 MPa. Leaf growth did not recover completely within the first three days after rewatering. All tissue water relations parameters, except the bulk modulus of elasticity, changed significantly as the soil dried and recovered completely by 3 days after rewatering. The changes in osmotic pressure at full turgor of 0.4 MPa indicates considerable ability by E. marginata seedlings to adjust osmotically. However, there was little osmotic adjustment until predawn leaf water potential fell below -1.5 MPa so it would not have conferred any advantage to the growth of the seedlings, but may aid in survival. The sensitivity of photosynthesis and relative water content to water deficits shows that E. marginata behaves as a mesophyte despite the fact that it grows in a drought-prone environment. The glasshouse experiments dealing with the effects of soil temperature and shade showed that both the higher soil temperatures and the higher light intensities on sites with the overstorey removed could account for significant increases in growth of E. marginata seedlings, but that these effects were a relatively small component of the growth response due to overstorey removal. The glasshouse experiment on the effects of water deficits showed that rates of leaf growth and photosynthesis are very sensitive to water deficits and therefore the greater water deficits that seedlings experienced on sites with the overstorey retained will cause large reductions in the growth of E. marginata seedlings. In conclusion, secondary effects of overstorey removal are increases in soil temperature and light which promote greater growth of E. marginata seedlings. The major effect of overstorey removal is to reduce some of the limits that water deficits impose on growth of E. marginata seedlings in the northern jarrah forest of south west Western Australia. The major factors affecting establishment of E. marginata seedlings in the forest were seed harvesting by small vertebrates which greatly reduced emergence, and water deficits which increased mortality and reduced growth of E. marginata seedlings.

[Truncated abstract. Please see the pdf format for the complete text. Also, formulae and special characters can only be approximated here. Please see the pdf version for an accurate reproduction.] This thesis examines the water use, ecophysiology and hydraulic architecture of Eucalyptus marginata (jarrah) growing on bauxite mine rehabilitation sites in the jarrah forest of south-western Australia. The principal objective was to characterise the key environment and plant-based influences on tree water use, and to better understand the dynamics of water use over a range of spatial and temporal scales in this drought-prone ecosystem. A novel sap flow measurement system (based on the use of the heat pulse method) was developed so that a large number of trees could be monitored concurrently in the field. A validation experiment using potted jarrah saplings showed that rates of sap flow (transpiration) obtained using this system agreed with those obtained gravimetrically. Notably, diurnal patterns of transpiration were measured accurately and with precision using the newly developed heat ratio method. Field studies showed that water stress and water use by jarrah saplings on rehabilitation sites were strongly seasonal: being greatest in summer when it was warm and dry, and least in winter when it was cool and wet. At different times, water use was influenced by soil water availability, vapour pressure deficit (VPD) and plant hydraulic conductance. In some areas, there was evidence of a rapid decline in transpiration in response to dry soil conditions. At the end of summer, most saplings on rehabilitation sites were not water stressed, whereas water status in the forest was poor for small saplings but improved with increasing size. It has been recognised that mature jarrah trees avoid drought by having deep root systems, however, it appears that saplings on rehabilitation sites may have not yet developed functional deep roots, and as such, they may be heavily reliant on moisture stored in surface soil horizons. Simple predictive models of tree water use revealed that stand water use was 74 % of annual rainfall at a high density (leaf area index, LAI = 3.1), high rainfall (1200 mm yr-1) site, and 12 % of rainfall at a low density (LAI = 0.4), low rainfall (600 mm yr-1) site, and that water use increased with stand growth. A controlled field experiment confirmed that: (1) sapling transpiration was restricted as root-zone water availability declined, irrespective of VPD; (2) transpiration was correlated with VPD when water was abundant; and (3) transpiration was limited by soil-to-leaf hydraulic conductance when water was abundant and VPD was high (> 2 kPa). Specifically, transpiration was regulated by stomatal conductance. Large stomatal apertures could sustain high transpiration rates, but stomata were sensitive to hydraulic perturbations caused by soil water deficits and/or high evaporative demand. No other physiological mechanisms conferred immediate resistance to drought. Empirical observations were agreeably linked with a current theory suggesting that stomata regulate transpiration and plant water potential in order to prevent hydraulic dysfunction following a reduction in soil-to-leaf hydraulic conductance. Moreover, it was clear that plant hydraulic capacity determined the pattern and extent of stomatal regulation. Differences in hydraulic capacity across a gradient in water availability were a reflection of differences in root-to-leaf hydraulic conductance, and were possibly related to differences in xylem structure. Saplings on rehabilitation sites had greater hydraulic conductance (by 50 %) and greater leaf-specific rates of transpiration at the high rainfall site (1.5 kg m-2 day1) than at the low rainfall site (0.8 kg m-2 day1) under near optimal conditions. Also, rehabilitation-grown saplings had significantly greater leaf area, leaf area to sapwood area ratios and hydraulic conductance (by 30-50 %) compared to forest-grown saplings, a strong indication that soils in rehabilitation sites contained more water than soils in the forest. Results suggested that: (1) the hydraulic structure and function of saplings growing under the same climatic conditions was determined by soil water availability; (2) drought reduced stomatal conductance and transpiration by reducing whole-tree hydraulic conductance; and (3) saplings growing on open rehabilitation sites utilised more abundant water, light and nutrients than saplings growing in the forest understorey. These findings support a paradigm that trees evolve hydraulic equipment and physiological characteristics suited to the most efficient use of water from a particular spatial and temporal niche in the soil environment.

Abstract:
Alcoa of Australia Limited mines bauxite from the Darling Range in south-west Western Australia. They have a goal to replace >80% of plant species indigenous to the surrounding jarrah (Eucalyptus marginata Donn ex Smith) forest in their 15 month old rehabilitation by 1997. Annual monitoring of the 15 month old rehabilitation has identified some plant species that germinate well in glasshouse and laboratory trials but were not returning to the rehabilitated areas m expected numbers. It was hypothesized that Phytophthora cinnamomi Rands and Phytophthora citricola Sawada, which had been recovered from soil and diseased vegetation in the pits may have been reducing establishment of these species. This project aimed to determine whether P . cinnamomi and P. citricola could cause damping-off of native plant species in bauxite pit rehabilitation. To achieve this aim five preliminary experiments, followed by a glasshouse experiment and an experiment based in a rehabilitated bauxite pit, were undertaken. The preliminary glasshouse and laboratory experiments determined mean percentage germination, as well as isolating seed testa fungi, for six native plant species identified as not returning in expected numbers to the rehabilitation. The plant species chosen were Clematis pubescens Huegel ex Endl., Cyathochaeta avenacea Benth., E. marginata. H akea lissocarpha R.Br., H ovea chorizemifolia (Sweet) DC. and Xanthorrhoea preissii Endl. Soil from rehabilitated pits was also shown to not cause suppression of P. cinnamomi and P. citricola. An appropriate density of millet seed for use in the main glasshouse experiment was determined and the process of soil solarization was investigated to determine whether it could be used to eradicate phytophthora species from soil in rehabilitated bauxite pits. The method of soil solarization used in this project was found to not be effective in eradicating Phytophthora species from the rehabilitated areas. The two main experiments tested the pathogenicity of P . cinnamomi and P. citricola on seed and seedlings of the six native plant species chosen for this study, in the glasshouse and rehabilitated bauxite pit environments. Both P. cinnamomi and P. citricola were found to cause post-emergent damping-off of E. rna r gina ta in the glasshouse, with P. cinnamomi also causing damping-off of X. preissii seedlings in this environment. An introduced isolate, as well as indigenous isolates of P. citricola caused pre and post-emergent damping-off of E. marginata in the field. P. citricola also caused pre-emergent damping-off of H. lissocarpha in the rehabilitated trial areas. The P. cinnamomi inoculum did not cause disease in the field due to sub-optimum ambient temperatures which inhibited sporangia! formation and mycelial growth (Shearer and Tippett, 1989). However, P. cinnamomi has been shown to cause damping-off in regenerating areas (Mwanza and Kellas, 1987) and probably causes damping-off in Alcoa's rehabilitated areas when conditions are more favourable, in autumn and spring. P. cinnamomi and P. citricola therefore probably reduce the biodiversity of Alcoa's rehabilitated pits by reducing the establishment of susceptible species. Topics requiring further research are discussed.

Abstract:
Phytophthora cinnamomi is an introduced soilborne phytopathogen to Western Australia (WA) and impacts on 2000 of the approximately 9000 plant species indigenous in the southwest of WA. Amongst these is Eucalyptus marginata (jarrah), the dominant and economically important hardwood timber species of the jarrah forest. This thesis aimed to investigate the morphological, pathogenic and genotypic variation in two local WA populations of P. cinnamomi isolates. The populations were selected from areas where jarrah clonal lines selected for resistance to P. cinnamomi may be used in the rehabilitation of infested jarrah forest and rehabilitated bauxite minesites in the southwest of WA. Resistance against a range of isolates using different inoculation methods. Seventy-three isolates of P. cinnamomi were collected from diseased jarrah and Corymbia calophylla (marri) trees from two populations located 70 km apart and these were examined for phenotypic and genotypic variation. Microsatellite DNA analysis showed that all isolates were of the same clonal lineage. In P. cinnamomi for the first time I show that there is a broad and continuous variation in the morphology and pathology between two populations of one clonal lineage, and that all phenotypes varied independently from one another. No relationship was found between morphological and pathogenic characters. The ability of isolates in both populations to cause deaths ranged from killing all plants within 59 days to plants being symptomless 182 days after inoculation. Single and multiple paragynous antheridia formed along with amphigynous ones in mating studies with all WA isolates and a sample of worldwide isolates. Developmental studies and cytological examination showed fertilisation tubes developed asynchronously or synchronously from both antheridial types and indicated that either antheridial type contributed a nucleus for fertilisation of the oosphere. This is the first report of paragynous antheridial associations in P. cinnamomi. Antheridial variation is a characteristic that needs to be adjusted in the taxonomic Phytophthora identification keys. In underbark and zoospore stem inoculations of three 1.5-year-old jarrah clonal lines (two ranked as resistant (RR) and one as susceptible (SS) to P. cinnamomi in the original selection trials) at 15, 20, 25 and 30°C, it was found that the method of inoculation did not produce comparable results, particularly at 25 and 30°C. At these temperatures, all three clonal lines had 100% mortality when inoculated underbark, but when inoculated with zoospores, one RR line had 60% survival and the SS and remaining RR line had 100% mortality. Generally, the level of resistance of all clonal lines declined with increasing temperature. Lesion development was measured at 20, 25 and 30°C for 4 days in detached branches of an RR and SS clonal line inoculated underbark with four different P. cinnamomi isolates. Detached branches were found to be a potential screen for jarrah resistance to P. cinnamomi and to allow the identification of susceptible and resistant clonal lines at 30°C. Lesion and colonisation development of P. cinnamomi isolates were assessed in situ (late autumn) of seed-grown and clonal lines of 3.5 to 4.5 year-old jarrah trees growing in a rehabilitated minesite jarrah forest in underbark inoculation of lateral branches (1995) or simultaneously in lateral branches and lateral roots (1996). Trees were underbark inoculated in lateral branches and lateral roots. Colonisation was more consistent as a measure of resistance than lesion length over the two trials because it accounted for the recovery of P. cinnamomi from macroscopically symptomless tissue beyond lesions, which on some occasions, was up to 6 cm. In the two trials, one RR clonal line consistently had small lesion and colonisation lengths in branches and roots. In contrast, the remaining two RR clonal lines had similar lesion and colonisation lengths to the SS clonal line and may, therefore, not be suitable for use in the rehabilitation of P. cinnamomi infested areas. The relative rankings of the jarrah clonal lines by colonisation lengths were similar between branch and root inoculations. Branch inoculations are a valid option for testing resistance and susceptibility of young jarrah trees to P. cinnamomi. The pathogen was recovered on Phytophthora selective agar 3–6 months after inoculation from 50% of samples with lesions and 30% of symptomless samples in a series of growth cabinet, glasshouse and field experiments. However, up to 11% of samples with and without lesions and from which P. cinnamomi was not initially isolated contained viable pathogen after leaching the plant material in water over 9 days. This indicates that the pathogen could be present as dormant structures, such as chlamydospores, where dormancy needs to be broken for germination to occur, or fungistatic compounds in the tissue need to be removed to allow the pathogen to grow, or both. These results have important implications for disease diagnosis and management, disease-free certification and quarantine clearance. No clonal line of jarrah was found to be 100% resistant using different inoculation methods, environmental conditions and when challenged by individuals from a large range of P. cinnamomi isolates. Even the most promising RR line had individual replicates that were unable to contain lesions or died with time. This suggests that further screening work may be required using more isolates varying in their capacity to cause disease and a broader range of environmental conditions. Jarrah clonal lines that survive such rigorous screening could then be expected to survive planting out in a range of environments in the jarrah forest and rehabilitated bauxite minesites.

Abstract:
Globally, forests cover 31% of the Earth’s land mass and are critical areas for water supply. In Australia, forested catchments provide 77% of urban water supplies to capital cities. However, recent studies have reported worldwide examples of forest damage resulting from drought or heat related events. The jarrah (Eucalyptus marginata) forests of south-west Western Australia (SWWA) have experienced both sudden and unprecedented forest collapse and profound reductions in streamflows. Projected further declines with climate change, reinforce the need to understand the hydrologic impact of forest disturbance and what management responses are needed to enhance forest resilience and productive capacity. The aim of this thesis was to understand the impact of disturbance and climate on the hydrology of the forests of SWWA, with objectives to: 1. Examine the characteristics of forest hydrology; 2. Evaluate the hydrologic response to forest disturbance and climate variability; and 3. Evaluate forest water management options in the context of forest disturbance and climate change. This thesis thus develops an understanding of the impact of disturbance and climate on the hydrology of the forests of SWWA. Using hillslope and paired catchment studies (Chapter 3), it develops an understanding of the process of infiltration and soil water dynamics and examines the hydrologic impact of forest disturbance. The studies demonstrate the important roles of infiltration, soil water dynamics, and groundwater on the forest water balance, and identify the major factors that impact forest disturbance and forest hydrology. These studies have improved understanding of factors contributing to catchment water balance, and streamflow generation processes. Four catchments underwent land use change and the impact on catchment hydrology was studied by comparing with a control catchment (Chapter 4). These paired catchment studies evaluated the impact of converting forest to agriculture and of timber harvesting. They explored the streamflow generation mechanisms for forested and cleared catchments, the streamflow generation and salinity export changes due to clearing for agriculture, and the hydrologic impact of intense timber harvesting for increased water production. The impacts of deforestation, forest thinning, bauxite mining, bushfires, dieback disease, and reforestation were evaluated using several paired catchment studies across SWWA (Chapter 5). The long-term implications for management of water yield, the impact of a range of disturbances at a catchment scale, and the impact of forest disturbances on stream salinity are also examined. The relationship between the drying climate observed in SWWA over the last 40 years and observed changes in rainfall, groundwater levels, streamflow volumes and flow duration were studied in Chapter 6. The changing relationship between rainfall and streamflow and the likely implications of recent climate change scenarios are also studied. The major forest water issues that have been identified in this thesis are the declining water values in forested areas, such as less water volumes, shorter flow periods, and declining groundwater levels. The adaptive strategies for forest ecosystems are identified to include resistance (protect highly valued areas), resilience (improve capacity to return to pre-disturbance conditions) and response (assist transition to new condition) are discussed in Chapter 7. Drivers identified (Chapter 7) by this thesis include (a) a drying climate with direct and indirect impacts on both the forest itself and on the overall water balance, (b) responses to historical forest management including forest harvest, deforestation and reforestation, (c) long-term impacts of bauxite mining and subsequent rehabilitation, and (d) the interaction of these forest disturbances at a catchment scale. The major findings from this study include: - The high saturated hydraulic conductivity of the sandy gravel topsoil overlies lateritic durcirust with a much lower saturated hydraulic conductivity; - The presence of large infilled “holes” within the lateritic duricrust; - Saturation above the lateritic duricrust was observed confirming subsurface flow concepts; - Presence of vertical preferential flow observed confirming soil water concepts; - The critical importance of the groundwater discharge area in streamflow generation; - Increase in stream salinity directly linked to groundwater levels approaching the surface; - The time to leaching of the salt from the catchment estimated at 200 years; - Forest disturbances such as clearing, timber harvesting and forest thinning led to increased streamflow but with significant delays related to the presence or lack of a groundwater discharge area; and - The extensive reduction in streamflow across the south west has ranged from 36 to 52% (1975 to 2000 compared to 2001 to 2012) seen as a delayed response to rainfall reductions from 1930 to 2000. The challenge for the future is for forest hydrology research to influence current and future forest management to improve environmental and water supply outcomes for the forests of not only SWWA, but globally. Understanding the impact of land-use change on hydrology, water quality and on water resources, and separating this from climate variability and change, is a recurring problem globally. Further understanding is thus needed of the causes of changing forest hydrology and of management options to ultimately improve forest outcomes.

Abstract:
The present study examined the home range and microhabitat selection by Tiliqua rugosa and Egernia napoleonis in the jarrah forest of southwest Western Australia. The aim of the study was to compare the microhabitats used by T. rugosa with the microhabitats used by E. napoleonis and discuss why T. rugosa was located in rehabilitated bauxite mined areas, whereas E. napoleonis was not. The overall objective of the present study was to identify methods which may be incorporated into the management of rehabilitated bauxite mined areas operated by Alcoa World Alumina Australia, to accelerate the return of T. rugosa and E. napoleonis. A total of five Tiliqua rugosa and eight Egernia napoleonis were radio tracked from October 2005 until January 2006. The 100% home range average of T. rugosa was significantly larger than that of E. napoleonis. There was no significant difference in 50% Core home range average between the two species. The home range of T. rugosa was made up of native jarrah forest and rehabilitated mined areas. E. napoleonis were only found in native jarrah forest. The microhabitats significantly selected by Tiliqua rugosa in the native jarrah forest and rehabilitated mined areas were shrubs and leaf litter. In the native jarrah forest spikey and dome-shaped shrubs were significantly selected, but when in the rehabilitated mined areas spikey shrubs were significantly selected, which was probably due to the scarcity of dome-shaped shrubs in the rehabilitated areas. The selected microhabitats of Egernia napoleonis were logs and trees. The Eucalyptus marginata logs selected by Egernia napoleonis had a mean diameter of 42 ± 2lcm, whilst the Corymbia calophylla logs had a mean diameter of 48 ± 6cm. E. napoleonis did not differentiate between tree species of log. Common characteristics of logs selected by E. napoleonis were the presence of cracks, hollows, and some degree of fire damage. In the present study no logs were located in rehabilitated mined areas. The trees selected by Egernia napoleonis were significantly larger than a random selection of those found in native jarrah forest or those found in rehabilitated mined areas. Eucalyptus marginata selected by E. napoleonis had an average diameter at breast height of 73 ± 16cm whilst Corymbia calophylla had an average diameter at breast height of 58± 15cm. Species of tree were not differentiated by E. napoleonis. Both microhabitat structures (logs and large trees) selected by Egernia napoleonis were unable to be located in rehabilitated mined areas. The spikey shrubs and leaf litter microhabitats selected by Tiliqua rugosa were present in native jarrah forest and rehabilitated mined areas. The present study has shown that a lack of suitable microhabitats was reducing the occurrence of E. napoleonis in rehabilitated mined areas. Methods to help rectify this problem are discussed.

Abstract:
Worldwide, extreme climatic events such as drought and heatwaves are associated with forest mortality. While many studies address the immediate impacts of forest die-off events, information about the ongoing structural and compositional consequences is lacking. The Northern Jarrah (Eucalyptus marginata) Forest of southwestern Australia experienced a severe tree die-off event during a drought-associated heatwave. Using transects spanning a gradient of drought impacts (severe, transitional, minimal), tree species mortality in relation to soil depth and stand condition (stand basal area, stem density) was quantified. Differential mortality was exhibited by the two dominant overstorey species and two midstorey tree species, which occurred in distinct zones along the transects. The dominant, structural forest species Eucalyptus marginata (jarrah), had higher mortality than the co-dominant Corymbia calophylla and midstorey species Allocasuarina fraseriana. The midstorey tree (Banksia grandis) exhibited the highest stem mortality and a substantial shift in structure in response to the drought-associated heatwave in relation to tree size, soil depth and stand basal area. Banksia grandis represents a drought intolerant species. Regeneration of tree species was surveyed over three years and was greater in areas of high drought-impact than in healthy forest. To determine the response of understorey communities to the droughtassociated heatwave and subsequent changes in forest canopy, the abundance, composition and structure of understorey species was compared among drought-impact zones. In areas of high drought-impact, understorey communities showed different species assemblages and higher richness and cover than in healthy forest. The recovery of tree canopy following the event was studied by examining the temporal response of Eucalyptus marginata (jarrah) trees in zones of drought-impact and healthy forest using dendrometer bands. Trees growing in the high drought-impact zone had greater stem-diameter growth than trees in adjacent healthy forest. This study provides valuable insights into the consequences of a droughtassociated heatwave in driving structural and compositional changes in jarrah forest vegetation and highlights the importance of studying all components of the vegetation following forest mortality events

Abstract:
Restoration is an important tool in conserving biodiversity, yet passive faunal recolonisation may take decades, or longer, to occur. This is of particular conservation importance in biodiversity hotspots, such as south@western Australia, which are experiencing increasing fragmentation and rapidly drying climates. Within this hotspot, I investigated the response of nine insectivorous tree@dwelling bat species to restored mine@pits in jarrah (Eucalyptus marginata) forests. I assessed bat activity in restored, relative to unmined, forests and the suitability of restoration as foraging and roosting habitat. Bat echolocation call surveys measured bat activity in varying ages of restoration and unmined forest across two years (2010@2012) during both maternity and mating seasons. Although all bat species were detected in both forest types, restored mine@pits of all ages had significantly different bat communities and lower overall activity compared to unmined forest. Habitat filters to bat use of restoration were evident for the more manoeuvrable bat species and were predominantly related to midstorey forest structure. Tree density was the most important predictor of bat use of restoration for less manoeuvrable bat species. To determine the suitability of restored forest as foraging habitat I investigated the diet of three species (Chalinolobus gouldii, Nyctophilus gouldi and Vespadelus regulus) over maternity and mating seasons (2010/2011) by examining prey remains in faecal samples. I used high@throughput sequencing and bioinformatics analyses to phylogenetically group prey DNA and found that niche partitioning occurred, with dietary divergence positively related to bat ecomorphological divergence. In addition, I assessed the foraging potential of restored forest and found that prey occurrence did not necessarily equate to prey accessibility for all bat species. There was a synergistic effect of vegetation structure and insect biomass for edge foraging bat species. To determine the suitability of restoration as roosting habitat I used telemetry to radio@track 36 bats from two species (N. gouldi and V. regulus) to 59 distinct roosts. Not one bat was found roosting in restored forest and individuals preferred roosting in mature, tall trees in intermediate to late stages of decay. My research clearly shows that restored forest does not yet provide suitable foraging or roosting habitat for all jarrah forest bats. Improving habitat suitability through management manipulations, such as thinning and burning, may accelerate bat recolonisation of restored forest. In the interim, retention of mature forest patches is necessary for conserving and maintaining bat populations across restored landscapes.

Abstract:
Desgaitasuna duten Pertsonentzako Euskal Autonomia Erkidegoko Gizarte eta Lanerako Inklusio Eredua duela 40 urte baino gehiago hasi zen garatzen. Balio, tresna, jarduera eta baliabideen sistema partekatua da, Euskal Autonomia Erkidegoan desgaitasuna duten pertsonen inklusioa bultzatzeko. Hala ere, ziurgabetasunezko testuinguru globalak; inklusioaren “olatuak”; eta hiru trantsizio jasangarriek ekarriko dituzten erronkek eta aukerek behar-beharrezko egiten dute lurraldeko eragile publiko eta pribatuen artean ikuspegi partekatu bat eraikitzea landu behar diren erronken inguruan, Ereduak Euskal Autonomia Erkidegoan ongizatea helburu duen lehiakortasunari laguntzen jarraitzea nahi badugu. Lan hau eragile publiko eta pribatuen arteko elkarrizketarako oinarri gisa planteatzen da, eta hainbat ekintza identifikatzen ditu. Gainera, funtsezko rola ematen dio EHLABE-Euskal Herriko Lan Babestuaren Elkarteari, abian jarri nahi diren prozesuak bideratzeko.

Abstract:
Txosten honek, EAEko lehiakortasunaren azterketan etapa berri bat hastendu. 1. kapituluan, gure lurraldearen lehiakortasun ibilbidea aztertu dugu, orain dela 40 urte abian jarri zen estrategiak azken hamarkadan izan dituen ezaugarriei erreparatuta bereziki. Estrategia horrekin jarraitzeak gaur egun ekartzen dizkigun erronkak ere identifikatu ditugu. Estrategiaren hurrengo etapa bideratzeko, erronka horietatik abiatu gara eta, 2. kapituluan, lurralde lehiakortasuna bultzatzeko esparru berri bat proposatu dugu, tokian bertan eta nazioartean egindako gogoeta, alderatze eta esperimentazio prozesu baten ondoren. 3. kapituluan, EAEko lehiakortasunaren eta ongizatearen lehenengo diagnostikoa aurkeztu dugu, esparru berriaren ardatz nagusietan oinarrituta. Esparru berrian ongizatea helburu duen lehiakortasunerako sei palankak identifikatu ostean, 4. kapituluan, palanka horien dimentsioetako batzuen esplorazio analisia egin dugu. Bukatzeko, azken kapituluan diagnostikoaren ondorio nagusiak bildu ditugu eta esparruaren bilakaera bideratzeko pausoen inguruan gogoeta egin dugu, esparrua Euskal Autonomia Erkidegoko ongizaterako lehiakortasuna etengabe hobetzen lagunduko duen itsasargia izan dadin.

Canto, Patricia, ed. Europako elektrizitate merkatuaren diseinuaren erreforma. Universidad de Deusto, 2024. http://dx.doi.org/10.18543/ytxx4228.

Abstract:
2022an eta 2023an elektrizitate merkatuaren diseinuaren inguruko eztabaida sakona izan zen Europar Batasunean, zalantzan jarri baitzen diseinu hori egokiena ote zen energia merkatuetan estres egoereiaurre egiteko, kontsumitzaileak babesteko eta energia berriztagarritan beharrezkoak diren inbertsioak sustatzeko. Eztabaidan bi ikuspegi izan ziren aurrez aurre: (1) esku hartzearen aldeko jarrera (besteakbeste, Espainiako Gobernuak babesten zuena), merkatuko prezioak eta enpresa sortzaileen diru sarrerak kontrolatzea azpimarratzen zituena, gaur egun indarrean dagoen diseinua, neurri handi batean,baliogabetuz, eta (2) erreformaren aldeko jarrera, gaur egungo diseinua osatzea helburu zuena,merkatuaren erresilientzia eta kontsumitzaileen babesa hobetzeko elementuak txertatuta, EuropakoBatzordeak 2023ko martxoan egin zuen proposamenean jasotzen den bezala. Txosten honek eztabaida hori du aztergai eta Europako Parlamentuak eta Europako Kontseiluak 2023ko abenduan lortu zuten azken akordioaren xehetasunak azaltzen ditu. Akordio horrek Europako Batzordeak egindako erreforma proposamenaren funtsezko elementuei eutsi zien eta aldaketak proposatu zituen energiaren barne merkatuaren garapena osatzeko, kontsumitzaile kalteberenak babesteko, energiaren kostuaren egonkortasuna eta aurreikusgarritasuna handitzeko, eta energia berriztagarrietan eta malgutasunean inbertsioak egiteko pizgarriak sortzeko.

Abstract:
Humberto Salas Jara Académico de la Facultad de Administración y Negocios, Universidad Autónoma de Chile. Nuestra sociedad no será la misma después de esta crisis sanitaria que estremece al mundo y que se transformará en una crisis económica de similares características, de la cual debemos emerger fortalecidos. Así como lo expresó hace más de 60 años JF. Kennedy “en la crisis, se consciente del peligro, pero reconoce la oportunidad”, es también momento de vislumbrar el largo plazo y pensar en cómo cambiará la forma de generar ingresos y se modificarán los patrones de consumo, pues desde aquí germinarán muchos desafíos. Lo primero está relacionado con la evolución acelerada que tendrá el mercado del trabajo, donde empresas iniciarán un inevitable proceso de reestructuración en sus políticas y dotación de recursos humanos, enfocadas en nuevas y modernas formas de trabajo, incorporando tecnologías para responder a un consumidor con otras necesidades.
