Diagnosing river health using invertebrate traits and DNA barcodes. This project aims to develop indices that link change in invertebrate communities to specific environmental stressors, and combine these indices with innovative, low cost molecular approaches to species identification to rapidly identify the causes of decline. River health assessment methods, usually based on aquatic invertebrates, identify if rivers are impaired but must be developed to identify the causes of decline. The intended outcomes are improved sustainable water resource management within and among states, and improved natural resource policy development.Read moreRead less
Effects of maternal foraging success and oceanographic variation on offspring behaviour and survival in the southern elephant seal. Juvenile survival is the key determinant of mammalian population performance, but the proximate determinants of this have rarely been established in large, long-lived predators. Southern elephant seals, with their concentrated lactation effort and marked separation of energy acquisition (at-sea foraging) and expenditure (on-land lactation) provide an ideal model for ....Effects of maternal foraging success and oceanographic variation on offspring behaviour and survival in the southern elephant seal. Juvenile survival is the key determinant of mammalian population performance, but the proximate determinants of this have rarely been established in large, long-lived predators. Southern elephant seals, with their concentrated lactation effort and marked separation of energy acquisition (at-sea foraging) and expenditure (on-land lactation) provide an ideal model for investigating these factors. In this study, we investigate the partitioning of pre-partum performance (fat acquired in mothers) relative to spatial-temporal variation in ocean productivity and the effect of this expenditure on offspring condition and survival. Here, the final missing link of energy transfer and its effects on offspring will be a major outcome of this project.Read moreRead less
Managing endangered Banteng in a jointly-managed national park: contested values, Indigenous aspirations and resource use. Should north Australia's huge populations of feral animals be eradicated for conservation, or exploited as a rare opportunity for Aboriginal enterprise in remote regions? We examine options for a herd of Banteng, a cattle species endangered in its native Asian range but abundant in Gurig Ganak Barlu National Park, Aboriginal land managed jointly by traditional owners and a c ....Managing endangered Banteng in a jointly-managed national park: contested values, Indigenous aspirations and resource use. Should north Australia's huge populations of feral animals be eradicated for conservation, or exploited as a rare opportunity for Aboriginal enterprise in remote regions? We examine options for a herd of Banteng, a cattle species endangered in its native Asian range but abundant in Gurig Ganak Barlu National Park, Aboriginal land managed jointly by traditional owners and a conservation agency. In this unique cross-disciplinary study Aboriginal and non-Aboriginal stakeholders will identify Park values that may be threatened by Banteng. Those values will be incorporated in decision-support tools (bio-economic models) identifying tradeoffs between protecting values and providing incomes for Indigenous landowners.Read moreRead less
