The results of an ecological survey of the south-eastern Riverina are presented. The general features of the environment (climate, geology, physio- graphy, and soils) are described. Twenty-three plant associations are recognized and described and these are grouped into seven alliances and two formations. The distribution of the alliances is shown on the vegetation map of the region. The relationships between the vegetation and environmental factors are discussed. There is little correlation between the vegetation and geological formations. The distribution of the communities does not appear to be closely related to climatic factors, chiefly owing to the over-riding effects of soil and topography. Evidence is presented to show that the grasslands in the Narrandera, Urana, Jerilderie area are disclimax corninunities developed from the Acacia pendub-Atriplex nummularia Alliance. The life-form spectra of each alliance and of the whole region are given and briefly discussed. There is a preponderance of henlicryptophytes and therophytes except in the Eucalyptus dealbata-E. sideroxylon Alliance which is strongly nanophanerophytic. The appendix gives a species list for each alliance, together with notes on the occurrence of species rarely found in the region.

One New Species

The south-eastern Australian helicarionid clade currently comprises six genera of snails and semislugs united by genital characters, including an epiphallic flagellum that produces a spiraling, spinose spermatophore, the absence of an epiphallic caecum, and the presence of at most a very short vagina. We comprehensively revise the taxonomy of this group based on comparative analyses of key morphological features and mitochondrial markers COI and 16S, revise the placement of several species described recently on the basis of shell morphology alone, and describe new taxa. The snail genus Brevisentis is monophyletic as currently understood, but includes an additional undescribed species from Wollemi National Park, New South Wales. Mysticarion is shown to contain four arboreal semislugs with wide, disjunct ranges, including one new species (Mysticarion obscurior sp. nov.). We synonymise Fastosarion staffordorum with Mysticarion hyalinus. The semislug Desidarion is synonymised with Parmavitrina, and we describe two new species of this genus, P. flavocarinata sp. nov. and P. maculosa sp. nov. The semi-arboreal semislug Cucullarion is herein included in the south-eastern Australian helicarionid clade based on morphological and genetic evidence, despite its more northerly distribution. Two small semislugs so far placed in Peloparion do not group together and a new genus, Ubiquitarion gen. nov., is described for Peloparion iridis. All of these genera, together with the semislug Helicarion (not included here), form a monophyletic radiation endemic to southeastern Australia.

A general description of the disclimax communities in the south-eastem Riverina is presented.The disclimax communities are essentially the pastures developed on clearing some or all of the trees in the climax communities and grazing the herbaceous stratum. These pastures are discussed in relation to soil and the grazing factor. Notes on the occurrence of weeds and the possibilities of pasture improvement are given.

Abundance Fluctuations

The evidence of taxonomic differentiation in the Australian pilchard is reviewed. Three major groups (called races), located respectively in eastern, south-eastern, and south-western Australian waters, are distinguished by differences in growth rate. The boundary zone of the two former is near the New South Wales-Victoria bolder, but it is not certain to which of the two latter races the South Australian fish belong. The two former races are sukdivided into smaller, more or less separate stocks (populations), which are distinguished mainly by differences in mean number of vertebrae and in abundance fluctuations. There are at least two such groups in the eastern race, which meet between Port Jackson and Jervis Bay, and at least two in the south-eastern race. The pilchards of Cook Strait, New Zealand, are probably distinct from those of any Australian locality.

In south-eastern Australia, the greater long-eared bat (Nyctophilus timoriensis) has been rarely captured and is considered uncommon, although large areas within its range have received little survey effort. We collate existing capture records and present new data on N. timoriensis captures from recent fauna inventory surveys across the western slopes and plains of New South Wales (NSW). From 1628 trap nights at 39 study areas, 118 N. timoriensis were captured out of a total of 8266 bats. In larger remnants in the Brigalow Belt South Bioregion, N. timoriensis was captured at a rate of 0.1 to 0.6 per trap night and made up 7 to 9% of bat captures. This was approximately an order of magnitude greater than in other study areas throughout western NSW. There were no captures from the Darling Riverine Plains Bioregion. These surveys show that the large vegetation remnants of Goonoo, Pilliga West and Pilliga East study areas are a distinct stronghold in the distribution of the south-eastern form of N. timoriensis.

The association of an armoured scale insect (a diaspidid) with dieback of a population of a native cycad (Macrozamia communis L.A.S.Johnson) was investigated on the south coast of New South Wales. The diaspidid was found to be undescribed but morphologically similar to oleander scale – here we call it Aspidiotus cf. nerii. It is probably native to Australasia and its current known distribution is within Murramarang National Park (MNP). Aspidiotus cf. nerii has been abundant on symptomatic M. communis at MNP over at least the past decade and has spread to new parts of the park. In population studies of infested and uninfested areas we found that, although both areas had populations with reverse J curves showing dominance of seedlings, mortality of seedlings and caulescent plants was significantly higher in infested sites. Infested areas had been burnt less frequently than uninfested areas. Fire does not appear to eradicate the diaspidid but may reduce its effects enough for plants to recover. We recommend further research into the use of fire as a management tool. Although other factors may be contributing to the severity of the dieback, we suggest there is sufficient evidence for the diaspidid to be regarded as the primary cause of dieback in M. communis in MNP, regardless of its origin. Given the occurrence of similar diaspidids on cultivated plants in botanic gardens, translocation of threatened Macrozamia species using plants grown in nurseries should be undertaken with extreme caution.

Native forest at Durras in south-eastern New South Wales and Jarrahdale in south-western Western Australia was examined for the presence of Phytophthora cinnamomi by two sampling and isolation techniques. With the lupin seeding baiting technique, randomly selected samples of soil and fine roots collected from the New South Wales site yielded P. cinnamomi when baited, while similar baiting of comparable samples from Western Australia failed. Direct plating of samples of upper roots and root collars of recently dead Banksia grandis from Western Australian sites yielded P. cinnamomi, while this organism was not isolated from comparable samples of chlorotic Macrozamia communis collected at the New South Wales site. The results suggest that the form of occurrence of P. cinnamomi and its association with disease in Australia vary in different situations. Viewing each situation independently might ensure the adoption of control/prevention strategies appropriate to all.

Effect Of Age

Reproduction is an important driver of profitability in commercial sheep flocks. Historically, Merino flocks have been run with a fixed age structure, ignoring individual merit and casting for age at a specific age. More recently, research has focussed on utilising the variation within age groups by keeping productive older ewes longer and culling less productive ewes earlier. Previous studies have also examined the effect of age on reproduction and the impact of reproduction status on productivity, but little research has been conducted on cumulative effects of reproductive performance on later productivity, reproduction and health. The present study examined the impact of higher lifetime reproduction on other key production and fitness traits in older ewes run under commercial conditions. Data were collected from two commercial wool-producing properties in the South West Slopes and the Central West Plains of New South Wales during 2009–2011. Reproduction, fleece measurements, bodyweight and condition and dental health were recorded during the study. The results showed that age had a bigger effect on productivity and dental health than did cumulative lifetime reproduction. Environment and genetics determined the level of impact, with minimal loss in productivity from increased age of animals occurring in the South West Slopes flock, whereas the Central West Plains flock would appear to require closer monitoring of productivity as ewes aged. The data collected did not allow separation of the genetic and environmental influences within the study. Retaining animals with a higher reproductive performance past normal culling age does not necessarily result in reduction of productivity or ewe health, but this must be monitored.
