... on scat counts) within the Mountain Ash forests of the Victorian Central Highlands? We surveyed 86 long-term field sites and detected a total of 245 groups of Sambar Deer pellets on 42% of these sites. Negative binomial regression modelling identified three factors associated with the occurrence of deer...

...Allen Keast Times of occurrence and abundances of five Palearctic, and one New Zealand, migratory waders in Botany Bay over the period 1942 to 1966, are documented from Arnold McGill's unique data set. The Sharp-tailed Sandpiper occurred from early September to the end of February; Red-necked Stint...

... for representing pre-existing occurrence records of priority species at sites that differed in mapped fire severity classes as based on Fire Extent and Severity data available from public sources. We also surveyed unburnt sites for comparative purposes. We found that nearly all survey sites encompassed a patchwork...

...Bruce C. Chessman ABSTRACT Many freshwater turtle species have spread beyond their natural distributions through human agency, but introduced populations can be difficult to differentiate from natural ones. The occurrence of an Australian freshwater turtle, Emydura macquarii , in the Greater Sydney...

...N. Koch; S.A. Munks; M. Utesch; P.E. Davies; P.D. McIntosh This study examined the occurrence, relative abundance and condition of platypuses in the upper catchment of the South Esk River, in north-east Tasmania, Australia, and the impact of past forestry activities on the occurrence of platypuses...

... megafauna using real-time video and whether their presence was correlated with the occurrence of baitfish. Stingrays were observed more often than other species and the occurrence of seals was correlated with the presence of baitfish. The continuous coverage allowed the observation of foraging behaviour...

... this location in 2013 to determine whether the species still persisted in NSW and, if so, to document the extent of its distribution and its management requirements. The species was found at four of the 37 locations surveyed. These enclosed an area of 47.2 km 2 (extent of occurrence) with 12.5 km 2 of potential...

...Greg Gordon; Frances Hrdina; Ross Patterson We assessed decline in the distribution of P. cinereus in Queensland over the last century using historical data from P. cinereus surveys and the Queensland State Archives to measure change in extent of occurrence and area of occupancy. Broad distribution...

... Wales. Thirteen sites were surveyed in spring from 2001-2023. Breeding activity, including the occurrence of calling males, tadpoles, spawn and amplecting pairs was detected at 12 of the 13 surveyed sites. Within the duration of the surveys the south coast region experienced two major droughts, two...

... of occurrence for H. bornemisszai was increased from 4 to 28 and its extent of occurrence was calculated to be 1,200 ha (12 km 2 ). The number of sites of occurrence for H. vanderschoori was increased from 3 to 22 and its extent of occurrence was 9,510 ha (95 km 2 ). Both species appeared to have patchy...

... forest age, structural complexity, local food tree species diversity, history of prior koala occurrence and decreased past logging intensity. This relationship was driven primarily by breeding females, with the number of male koala calls weakly or uncorrelated with koala sightings and mapped habitat...

... recorded in 17% of black rats and Salmonella spp. in 21% of bandicoots. Our findings suggest black rats may be facilitating spill-over of disease into native wildlife. The detected prevalence of Angiostrongylus spp. suggests an increasing occurrence in this natural system. These data provide valuable...

... observed aggregations. Notably, the occurrences of these aggregations appeared to be influenced by seasonality, with each observation being made during late autumn or winter. The peak aggregation count documented involved six adult snakes. Brown tree snake Boiga irregularis communal aggregation...

...Harry F. Recher ABSTRACT Frequency of occurrence data are available for birds along a transect in Kings Park, Perth, Western Australia from 1928 to 2008. These data show a dynamic avifauna with about a third of the sixty-one bird species recorded declining in frequency since 1928, another third...
