.... Research into the effects of genetic diversity on the impacts of disease on wildlife populations has focussed on genes of the major histocompatibility complex (MHC). This study investigated the genetic diversity at the MHC class II DZB gene, as well as the distribution of alleles of the same gene...

... patterns is required to identify important environmental features. However, habitat use may differ between the different sexes and age classes due to different behavioural and resource requirements. For this study, we compared microhabitat use during the active breeding season among the sexes and age...

... to the St Bees Island population. It is concluded that, in Queensland at least, the tooth wear - age class classification should be verified with local data when applied in environments different from those of the Brigalow Belt. Further, the appropriateness of using a single tooth-wear classificatory scheme...

... site was allocated to one of three categories. At the Seal Slide, 1 to 11 pups were born over nine pupping seasons and it is classed as a breeding colony. At four sites (Black Point, Cave Point, Cape Bouguer and North Casuarina Island), small numbers of pups were recorded over two or more seasons...

...Gerasimos Cassis; Ryan Shofner; Shawn Laffan; Marina Cheng ABSTRACT This study examined the impact of the Black Summer 2019/20 wildfires in the Northeast Forests of New South Wales for seven priority heteropteran (= true bug) species, across a range of vegetation classes and host plants. Our area...

... ecological impact of each severity class on ecosystems, and priority species. Prioritising threatened species based on potential ecological impact rather than fire severity alone allows post-fire survey and monitoring to be better targeted to those species likely most severely impacted. It also allows...

... 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...

The objective of this review was to consider the current knowledge of CyHV3 transmission factors and discuss the potential for recurring epidemic-level mortality events in carp found in Australia. Case studies were presented comparing KHVD outbreaks...

... 1860, with habitat class 2A (30-<50 per cent of preferred habitat trees) and 2C (10-<30 per cent of preferred habitat trees) suffering the highest proportion of loss. The period of greatest habitat loss was between 1890 and 1910, linked to the development of the dairy industry in the western half...

... those populations undergoing moderate (5-10% shot/year) and low (0-5% shot/year) shooting intensities. There was no significant alteration in proportion of young (out-of-pouch) age classes with changes in shooting intensity. However the proportion of pouch-young significantly decreased with increases...

Unfed fish attacked all three size classes of tadpoles without any significant...

We compiled data collected over six surveys conducted...
