The project aims to quantify the movement patterns and habitat utilisation of the endangered eastern freshwater cod (Maccullochella ikei) at a larval, juvenile, adult and historical level. Most previous studies regarding the life-history of fish species have failed to adopt this holistic approach, with management often based on fragmented information. The project will also provide an insight into the biology of one of the most poorly understood coastal stream fishes of eastern-Australia and assist in ensuring the conservation of this endangered species, and offer a framework from which future studies into the life history of freshwater fish species worldwide can be based.Read moreRead less

Stocking of fish and prawns at ecologically determined densities into Australian estuaries. Increasing numbers of people like to go fishing, and to catch a fish, which translates into tourism income and aquaculture business. Restocking is a fisheries management option when the natural supply or survival of larvae is limited. This study will determine for the first time the ecologically appropriate abundance of small mulloway and prawns that an estuary can sustain. We will assess the extra eff ....Stocking of fish and prawns at ecologically determined densities into Australian estuaries. Increasing numbers of people like to go fishing, and to catch a fish, which translates into tourism income and aquaculture business. Restocking is a fisheries management option when the natural supply or survival of larvae is limited. This study will determine for the first time the ecologically appropriate abundance of small mulloway and prawns that an estuary can sustain. We will assess the extra effort needed to release larvae into particular key habitats, and develop new technologies to identify our larvae from the wild. Our findings will be relevant to restocking of Australia's inland rivers, which at present has little ecological basis.Read moreRead less
Nutrition in the Gouldian finch - developing an optimal 'life-history diet'. Native Australian birds such as the budgerigar, cockatiel, cockatoo, zebra finch and Gouldian finch dominate the pet trade with tens of millions kept across the world. Currently these birds are fed inadequate diets based on a few generic seeds (of European origin). Our study will investigate the nutritional needs of the Gouldian finch and the nutritional content of native Australian seeds, ultimately designing an optima ....Nutrition in the Gouldian finch - developing an optimal 'life-history diet'. Native Australian birds such as the budgerigar, cockatiel, cockatoo, zebra finch and Gouldian finch dominate the pet trade with tens of millions kept across the world. Currently these birds are fed inadequate diets based on a few generic seeds (of European origin). Our study will investigate the nutritional needs of the Gouldian finch and the nutritional content of native Australian seeds, ultimately designing an optimal diet that will dramatically improve the health of these captive birds. We will develop a new product based on Australian plants, which are adapted to growing in even in the poorest soils and climates in Australia and which will form the basis of a new commercial crop for domestic and international markets.

This research will provide fundamental information about how plantation water use and drought tolerance are modified by species diversity. This work has the potential to transform tree plantation establishment practices toward inclusion of greater species diversity or toward species with particular complementary traits. It has significant potential to enhance benefits from reforestation projects, including better drought survival, reduced water use, soil bioremediation and enhanced biodiversity. Read moreRead less
Improved seasonal rainfall prediction for grain growers using farm level data and novel modelling. Successful grain production, a key export commodity for Australia, depends heavily on reliable seasonal forecasts. However, the highly variable climate means that for Australia’s 25,000 grain growers current forecasts lack detail in space and time. Using a combination of fuzzy classification and artificial neural networks, this project will develop a locally detailed continuously updating data-driv ....Improved seasonal rainfall prediction for grain growers using farm level data and novel modelling. Successful grain production, a key export commodity for Australia, depends heavily on reliable seasonal forecasts. However, the highly variable climate means that for Australia’s 25,000 grain growers current forecasts lack detail in space and time. Using a combination of fuzzy classification and artificial neural networks, this project will develop a locally detailed continuously updating data-driven seasonal forecast system using high density climate data from the 17,000 Grain Growers Association members and climate drivers such as sea surface temperature from the Bureau of Meteorology. After validation against observed data, the forecasts will be delivered via a web-based portal to users.Read moreRead less

Elucidating the genetic basis of newly evolved metabolic functions in yeast. This project intends to research how complex metabolic pathways originate and evolve. This project will use cutting edge genome sequencing and molecular techniques to elucidate the heritable genetic basis of Baker’s yeast, which has been the selectively evolved to use xylose as a sole carbon source: something vital for second generation biofuel production that wild yeast cannot do. This project will combine detailed molecular characterisation of highly adapted yeast strains with a novel "molecular palaeontology" approach to trace the evolutionary process and identify functionally significant loci under selection. Detailed characterisation of this trait will accelerate the development of future yeast strains and test fundamental evolutionary theories.Read moreRead less
