Learning in a changing world: Maternal effects on offspring development and behaviour. The impact of anthropogenic change on Australia's biodiversity is of grave concern. It is therefore vital to understand the capacity of Australian fauna to adapt and change, despite environmental challenges. This project aims to quantify the potential for birds to respond to environmental challenges, by programming offspring with adaptive developmental profiles. By quantifying the effects of maternal stress ov ....Learning in a changing world: Maternal effects on offspring development and behaviour. The impact of anthropogenic change on Australia's biodiversity is of grave concern. It is therefore vital to understand the capacity of Australian fauna to adapt and change, despite environmental challenges. This project aims to quantify the potential for birds to respond to environmental challenges, by programming offspring with adaptive developmental profiles. By quantifying the effects of maternal stress over two generations, this project aims to determine whether mothers have the ability to alter rates of evolutionary change by employing epigenetic mechanisms. Combining lab trials with field data it will determine the biological relevance of these effects to a common, but declining bird, with relevance across Australian avifauna.Read moreRead less
Growing up with global change. This project aims to quantify how native bird populations will respond to global warming. The project will investigate how vulnerable nestling birds are to high temperatures, and the impact of early-life heat stress on adult performance and fitness in the wild. Although growing animals are most sensitive to heat, and stress during early-life often has irreversible negative effects, we know very little about long-term consequences of early-life heat stress. The inte ....Growing up with global change. This project aims to quantify how native bird populations will respond to global warming. The project will investigate how vulnerable nestling birds are to high temperatures, and the impact of early-life heat stress on adult performance and fitness in the wild. Although growing animals are most sensitive to heat, and stress during early-life often has irreversible negative effects, we know very little about long-term consequences of early-life heat stress. The intended outcomes will increase our capacity to predict impacts of climate warming before population declines become evident. Improved predictions are beneficial to identify urgent threats and optimise conservation efforts.Read moreRead less
Getting smaller as temperatures rise? Body size responses of Australian birds to climate change. Many animals appear to be declining in size as climate change occurs, but why this is so is unclear. Using historical records and museum specimens we will determine the factors underlying body size reductions in Australian birds, and especially the role of changing temperature and ecosystem productivity.
Can consistent individual differences in metabolic rate explain animal personality? Implications for fish and aquaculture in a warming climate. This project will determine if consistent individual differences in metabolic rate affect behaviour, growth, and reproduction in fish. If so, then we need to prepare for the fact that a warming climate will lead to reductions in fish growth and reproduction, because rising temperature directly increases metabolism and therefore maintenance costs.
Defining winning strategies in a changing Southern Ocean . The ecosystem of the Southern Ocean is extremely complex, and understanding its response to rapid climate change is challenging. The aim of the project is to use changes in the behaviour of marine predators to provide new measures of integrated changes in eastern Antarctic ecosystems throughout the winter. With novel combinations of electronic tagging, natural biogeochemical markers, and simulation modelling, the project expects to recon ....Defining winning strategies in a changing Southern Ocean . The ecosystem of the Southern Ocean is extremely complex, and understanding its response to rapid climate change is challenging. The aim of the project is to use changes in the behaviour of marine predators to provide new measures of integrated changes in eastern Antarctic ecosystems throughout the winter. With novel combinations of electronic tagging, natural biogeochemical markers, and simulation modelling, the project expects to reconstruct changes in animal behaviour in response to changes in the environment. The data is anticipated to explain ongoing large-scale shifts in Southern Ocean ecosystems, providing information needed to underpin future management and adaptation strategies.Read moreRead less
An integrated examination of the drivers of movements of large filter feeding organisms of high ecotourism value: a case study. This aim is to define key drivers behind movements of large filter-feeding organisms, using the manta ray as a model system. As dive eco-tourism often depends on the presence of such charismatic filter-feeding animals, an understanding of why animals occupy particular sites at particular times is important, especially in the face of climate change.
