Abstract:

Leaf characteristics of Eucalyptus globulus Labill. ssp. globulus vary in response to plant genotype, ontogenetic position and environmental conditions. Glasshouse-grown seedlings from provenances at St Marys, Tasmania, and Wilsons Promontory, Victoria, produced seedling leaves for 10 nodes before producing leaves of juvenile form. Tasmanian provenance seedlings began to produce juvenile leaves after 18 weeks, 4 weeks earlier than Wilsons Promontory seedlings. Tasmanian seedlings continued to produce juvenile foliage, whereas Wilsons Promontory seedlings began producing transitional leaves at 33 weeks. Successive transitional leaves ranged from the juvenile to the adult leaf form owing to variability in the rate of change of particular morphological and anatomical leaf characteristics. Retention of broad, thin, sessile, horizontally oriented, dorsiventral, hypostomatal juvenile leaves of Tasmanian seedlings assists in increasing growth rates under mesic conditions. Early production of thick, narrow, petiolate, vertically oriented, isobilateral, amphistomatal adult leaves by Wilsons Promontory seedlings appears to be related to the stressful conditions within its local habitat. An increase in amphistomy and the distribution of palisade mesophyll on both leaf surfaces with ontogenetic development was strongly related to leaf orientation and light interception, increasing the supply of CO2 for photosynthesis.

Abstract:

The New Holland mouse (Pseudomys novaehollandiae) is found in disjunct populations in coastal south- eastern Australia. This study assessed the diet of the species at four locations (Anglesea, Loch Sport, Providence Ponds and Wilsons Promontory) in Victoria, southern Australia, where it is very rare in abundance and distribution. Overall, P. novaehollandiae was found to consume considerable amounts of dicotyledon leaf (27%), fungi (19%), invertebrate (17%) and seed (14%). There was no significant difference in diet between males and females. Seasonal variations in the percentage of dicotyledon leaf and fungi consumed were recorded. There were also significant differences between localities in the consumption of fungi, root and invertebrate material. Dicotyledon leaf was the most commonly consumed food item at Anglesea, Providence Ponds and Wilsons Promontory, while fungi was the most important at Loch Sport. The dietary differences between localities are likely to be related to important habitat factors including vegetation floristics and successional age. The results indicate that P. novaehollandiae is an omnivore with an opportunistic foraging strategy.

Full text

Abstract:

A morphometric study of the Olearia phlogopappa species complex from throughout south-eastern Australia has confirmed species boundaries and resolved the infraspecific taxonomy of two species. It has shown O. phlogopappa (Labill.) DC., O. stellulata (Labill.) DC., O. lirata (Sims) Hutch., O. rugosa (F.Muell. ex W.Archer bis) Hutch. and O. brevipedunculata N.G.Walsh to be non-overlapping entities with unique morphological characters. O. stellulata is circumscribed to include only southern and western Tasmanian populations and those from the Otways and Wilsons Promontory in southern Victoria. O. rugosa is restricted to Victoria and a few isolated populations on Flinders Island and northern Tasmania. Four previously noted variants of O. rugosa from Victoria are here described as subspecies, along with the description of a fifth subspecies from northern Tasmania. Infraspecific boundaries of O. phlogopappa are here revised to include nine subspecies, six of which were previously included as varieties, and descriptions are made of three new subspecies.

Full text

Abstract:

Populations of Cercartetus nanus were investigated in three areas of Victoria: two areas of Banksia woodland at Wilsons Promontory National Park and an area of mixed eucalypt forest with an under- storey of B. spinulosa at Nar Nar Goon North, east of Melbourne. Most births occurred between November and March, but in areas where the dominant Banksia sp. flowered in winter they took place year-round. Most females produced two litters in a year, but some produced three. Males were reproductively active throughout the year. Litter sizes ranged from two to six, with a modal size of four. Pouch life lasted 30 days and weaning occurred at 65 days. Growth was rapid, young became independent immediately after weaning, and matured as early as 4.5-5.0 months old. Maximum longevity in the field was at least 4 years.

Full text

Abstract:

Senescence and death of 30-year-old post-fire Acacia verticillata scrub in areas originally supporting sclerophyll eucalypt forest were studied over a 6-year period at Wilsons Promontory, Victoria. The potential for eucalypt regeneration was also examined. On drier sites, A. verticillata has been replaced by drought-resistant Kunzea ambigua while on wet sites it has been replaced by waterlogging-tolerant Melaleuca ericifolia. In mid slopes A. verticillata is regenerating from soil seed in gaps in the field layer of Pteridium esculentum and Goodenia ovata and forming a patchy, uneven-aged stand. The composition of the mid-slope community is determined by the relative resistance of species to browsing and grazing. The failure of eucalypts to reclaim the scrub areas at this critical time has been due to poor seed crops, seed harvesting by ants and intense selective browsing. Exclosure plots have demonstrated the importance of herbivory in modifying this vegetation and indicate potential means of reafforestation without the intervention of fire.

Abstract:

In 2009, 4 major bushfires destroyed vast areas of Gippsland in eastern Victoria including the areas around Delburn, Bunyip, Churchill and Wilsons Promontory. These are collectively known as the 2009 Gippsland bushfires. Research was conducted to investigate the psychosocial recovery of young adults in these areas. Twenty young adults participated in the study and, while these young adults are not an homogenous group, commonalities were identified across their stories. Asked what would have helped their recovery, the participants all said that acknowledgment of their personal and age-specific needs was the single most important factor that enabled or impeded recovery. This paper describes some of their stories. The paper looks at how participants viewed acknowledgment and the effects of its absence on their psychosocial recovery and how they felt unacknowledged in local recovery supports. The paper reports on the findings of this research and suggests an approach for management and longer-term recovery support that is inclusive of the specific needs of young adults.

Full text

Abstract:

Pseudomys novaehollandiae is ‘Endangered’ in Victoria, where it is presently considered to be extant at only three localities Loch Sport, Providence Ponds, and Wilsons Promontory. This study aimed to determine indicators of suitable habitat for the species that could assist in identifying potential habitat and sites for planned re-introductions as part of a recovery program. Vegetation and site data (soils, topography, rainfall, fire age-time since fire) were assessed at localities where P. novaehollandiae was recorded. The species occurred in five structural vegetation groups - open-forest, woodland, heathland, shrubland, grassland, with the most common being open-forest and woodland. Grassland and shrubland were restricted to coastal sand-dunes in south Gippsland. Understorey vegetation at most sites was dominated by sclerophyllous shrubs ranging in cover from 10 - 70%. Classification of quadrats produced eight floristic groups in which the trend was for quadrats to cluster according to geographical location. Ordination confirmed the classification pattern and vector-fitting produced significant correlations between vector points and five variables: species richness, latitude, longitude, fire age and annual rainfall. The study identified a range of vegetation communities where P. novaehollandiae occurs and provided evidence that the species is not restricted to floristically rich and diverse heathlands. The findings can be used to determine further localities with suitable habitat. However, factors other than vegetation are also likely to be important in predicting suitable habitat.

Abstract:

Population differentiation and speciation in freshwater snails in a small geographic area were investigated in a study of the morphology and genetics of 75 populations of hydrobiid snails from streams on Wilsons Promontory, Victoria, Australia. At least four genetically definable species occur in sympatry. One (Fluvidona recta sp. nov.) is genetically isolated from the others and the other three (of which only F: turbata sp. nov. is named) appear to be closely related and distinguished by a nearly fixed allozyme (MPI) difference. Heterozygote frequencies for the diagnostic Mpi locus fall well below Hardy-Weinberg expectations in zones of sympatry. There is significant population subdivision within at least two of the genetic species, but as the partitions are allopatric they are not categorised taxonomically. The situation may be explained by the divergence of upland and lowland populations when sea levels fell during the Pleistocene with subsequent secondary contact and low levels of hybridisation in the contact zones. Generally, there is very low gene flow between even closely adjacent populations and extremely low flow between different catchments, F-ST between populations within the same tributary ranging from 0.02 to 0.14 and within adjacent tributaries of the same catchment ranging from 0.03 to 0.59. Some correlations between allozyme data and measured environmental variables were observed but none of these were consistent over all taxa. Size (shell length) appears to be influenced by environment, but shell shape and the length of the opercular smear are more correlated with genetic patterns. A notable lack of correlation between anatomy and genetic groupings was found, although there was some with shell and opercular morphology. Two additional species (F: gippslandica, sp. nov. and F: foris, sp. nov.) from areas adjacent to the Promontory are used as outgroups.

Full text

Abstract:

That there is intraspecific variation in teat-number in Antechinus agilis (agile antechinus) and A. swainsonii (dusky antechinus) has been known for a long time. Our aim was to determine whether other key morphometric traits differed among individuals with different numbers of teats. External body dimensions and pelage characteristics were measured on live individuals and compared. Within-species variation in some external body dimensions (tail, pes, and snout-vent length) coincided with teat-number differentiation in both antechinus species in the Otway Ranges, Victoria. Disparities in pelage colour and markings were apparent between A. agilis 6- and 10-teat phenotypes, but were not obvious among A. swainsonii teat phenotypes. Although small sample sizes obviated statistical analysis, we tentatively concluded that female A. agilis with 7, 8, or 9 teats in the Otway Ranges probably displayed morphometric and pelage characteristics intermediate between those of 6- and 10-teat individuals. A comparison of morphometric traits among 6-teat A. agilis from different geographic areas (Otways, Portland and Wilsons Promontory) also revealed some variation. This result was consistent with an expectation of clinal variation in external morphology among antechinus. Overall, this study indicates that localized disparities that are associated with teat-number, as well as clinal differences occurring over large geographic distances, contribute to intraspecific variation in external morphology in antechinus.

Full text

Abstract:

Specimens of all known taxa and putative entities belonging to the Banksia spinulosa complex were collected from Kuranda in northern Queensland, western to central Queensland and down the eastern coast of Australia to Wilsons Promontory in southern Victoria. These specimens were used to investigate morphological variation in habit, stems, leaves, inflorescences, fruits and seeds in the complex. Phenetic analysis (unweighted pair-group method with arithmetic mean, UPGMA, clustering and semi-strong hybrid multi-dimensional scaling, SSH–MDS, ordination) was performed on the full dataset of 233 entities using 33 characters (18 quantitative, two binary and 13 multistate). To facilitate visualisation of patterns in both clustering and ordination, we also analysed subgroups based on the results of the phenogram from the full dataset. The results showed that the five known and described taxa are phenetically distinct, viz. B. collina sens. str., B. cunninghamii sens. str., B. neoanglica, B. spinulosa and B. vincentia, and provided support for a further 12 morphometrically diagnosable entities, four of which could not be diagnosed with simple combinations of character states and require further investigation. The present study has highlighted that there is much more hidden morphological diversity in the B. spinulosa complex than has previously been recognised in any of the current competing taxonomies.

Full text

Abstract:

The accuracy of population abundance estimates of mammalian herbivores from faecal pellet counts is potentially affected by pellet decay. We collected fresh pellet groups from hog deer (Axis porcinus), European rabbit (Oryctolagus cuniculus), eastern grey kangaroo (Macropus giganteus), swamp wallaby (Wallabia bicolor) and common wombat (Vombatus ursinus) (n = 300 per species) at Wilsons Promontory National Park, Victoria, Australia. We deposited five pellet groups per species per month within each of five vegetation types in the park, then monitored pellet group decay over 24 months. We demonstrate that age estimation of pellet groups was inaccurate and is unlikely to improve the efficiency of pellet counts. We present habitat- and species-specific estimates of pellet and pellet group decay using two measures: decay rate (the proportion of pellets surviving per unit of time); and mean time to decay. We explain how our data can be used to optimise faecal pellet count design, and to improve the accuracy of both indices and estimates of abundance from pellet counts. The variability observed in the decay of pellet groups among vegetation types, and for species among seasons, suggests that caution should be used if applying pellet decay rates over long time-frames or to locations with differing environmental conditions.

Full text

Abstract:

Habitat use is the most common dimension along which sympatric species partition resources to reduce competition. We conducted faecal pellet counts at Wilsons Promontory National Park, Victoria, to examine habitat use by an assemblage of mammalian herbivores with disparate evolutionary histories and varying body size: introduced European rabbit (Oryctolagus cuniculus) and hog deer (Axis porcinus), and native eastern grey kangaroo (Macropus giganteus), swamp wallaby (Wallabia bicolor) and common wombat (Vombatus ursinus). Overlap in habitat use was low between four pairs of species, suggesting spatial partitioning of resources to reduce the potential for interspecific competition. More generally, however, overlap in habitat use was high, particularly between native and introduced grazers. These results indicate the potential for competition if resources were limiting and suggest that assemblages of species with independent evolutionary histories have inherently less resource partitioning to facilitate coexistence than assemblages of species with common evolutionary histories. Despite evidence of high overlap in habitat use between native and introduced species at a broad scale, and variation in the competitive ability of species, coexistence was likely facilitated by niche complementarity, including temporal and fine-scale partitioning of spatial resources. There was no relationship between body size and the diversity of habitats used. In contemporary assemblages of native and introduced species, evolutionary history is likely to have a strong influence on resource partitioning.

Full text

Abstract:

Effective management of sympatric mammalian herbivore populations requires an understanding of interspecific interactions. At Wilsons Promontory National Park, Victoria, sympatric native and introduced mammalian herbivores are thought to be contributing to modification of shrub-encroached Coastal Grassy Woodland. We estimated the diets of the five terrestrial mammalian herbivore species present using microhistological techniques. The diets of introduced hog deer (Axis porcinus) and native swamp wallabies (Wallabia bicolor) consisted mainly of dicots. The diet of introduced European rabbits (Oryctolagus cuniculus) contained similar proportions of monocots and dicots. The diets of native eastern grey kangaroos (Macropus giganteus) and native common wombats (Vombatus ursinus) consisted mainly of monocots but kangaroos also consumed moderate amounts of dicots. Deer and wallabies consumed more native plants than did the other species and rabbits consumed more exotic plants than did all other species except kangaroos. Diet breadth was narrowest for kangaroos and broadest for swamp wallabies and hog deer. Overlap in food use by the five herbivores was high, particularly between deer and wallabies, and between kangaroos and both rabbits and wombats. Our results suggest that the potential impacts of native and introduced species on the vegetation of Coastal Grassy Woodland are similar, and that the entire herbivore assemblage will need to be managed to increase fine fuel loads if fire is used as a restoration tool.

Full text

Abstract:

Adjacent heath and woodland sites at Wilsons Promontory in Victoria support at least 50 species of ants, with the most abundant being Rhytidoponera victoriae, Iridomyrmex spp. (nitidiceps group), Notoncus hickmani, Aphaenogaster longiceps, Camponotus ?intrepidus and Plagiolepis sp. Total numbers of individuals and species in the woodland were twice that in the heath; this was probably caused by the greater structural complexity of vegetation there, which increased the availability of nesting and foraging sites, the level of insolation of the ground, and possibly also food supply. Total ant activity followed seasonal cycles which correlated with changes in temperature and probably also food supply, and, within these constraints, was regulated by prevailing weather conditions. Individual species displayed distinctive foraging schedules which possibly play an important role in species coexistence. Community organization is analysed according to a scheme derived from studies of ants in arid Australia, where taxa are classified according to their physical requirements and their relationships with dominant species. Although the major species in the present study were separated by differences in body size, food type, and time of foraging, interspecific competition appears to be less important than it is in arid regions. At both sites, opportunistic species (Rhytidoponera) predominated, cryptic species (those associated with soil and litter, such as Plagiolepis sp. and Solenopsis sp.) were abundant, and Iridomyrmex appeared to have a relatively weak influence on the abundance of other ants. This contrasts with the situation in arid regions, where species of Iridomyrmex are extremely important, and opportunistic and cryptic species are often rare or absent.
