Tracking warning signals across a variable landscape. This project aims to investigate how local environmental factors and predator communities affect warning colour expression across the Australian landscape. Warning colours protect toxic prey from predators who learn to associate the colours with an unpleasant taste. Theoretically, warning colours should not vary, but in nature we find appreciable and unexplained variation. This project will utilise Australia's excellent environmental and biod ....Tracking warning signals across a variable landscape. This project aims to investigate how local environmental factors and predator communities affect warning colour expression across the Australian landscape. Warning colours protect toxic prey from predators who learn to associate the colours with an unpleasant taste. Theoretically, warning colours should not vary, but in nature we find appreciable and unexplained variation. This project will utilise Australia's excellent environmental and biodiversity informatics infrastructure to inform the public and decision makers about the adaptability of animals to environmental change such as predator loss.Read moreRead less
Early-life climate sensitivity: direct and indirect mechanisms. This project aims to investigate how climate change threatens animal populations by determining the mechanisms causing DNA damage (short telomeres) in nestling birds growing up in hot conditions. Telomeres are biomarkers of individual life expectancy, and short telomeres in young birds predict a decline in future population viability. Our project aims to determine the importance for heat-induced telomere shortening of: (1) nestling ....Early-life climate sensitivity: direct and indirect mechanisms. This project aims to investigate how climate change threatens animal populations by determining the mechanisms causing DNA damage (short telomeres) in nestling birds growing up in hot conditions. Telomeres are biomarkers of individual life expectancy, and short telomeres in young birds predict a decline in future population viability. Our project aims to determine the importance for heat-induced telomere shortening of: (1) nestling heat stress responses; (2) inheritance of heat-shortened sperm telomeres; and (3) parental buffering of heat effects. Expected benefits include enhanced reliability of climate change predictions and improved ability to identify climate change mitigation strategies before population declines are evident.Read moreRead less
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.

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

Eco-evolutionary consequences of evolutionary shifts in body size. This project aims to understand the biological consequences of evolutionary shifts in body size at three levels of biological organisation: individuals, populations, and communities. Human-mediated body size declines in natural animal populations are a new emerging threat to the function of ecosystems, but few studies have explored the consequences of such declines. This project will use the tractability of the study species to d ....Eco-evolutionary consequences of evolutionary shifts in body size. This project aims to understand the biological consequences of evolutionary shifts in body size at three levels of biological organisation: individuals, populations, and communities. Human-mediated body size declines in natural animal populations are a new emerging threat to the function of ecosystems, but few studies have explored the consequences of such declines. This project will use the tractability of the study species to discover how evolutionary shifts in body size alter biological processes. This project can expand understanding of the biological consequences of ongoing worldwide declines in body size in animals.Read moreRead less
Behavioural resilience to climatic variability. Despite Australian biota being adapted to high natural climate variability, modern climate change is leading to population collapses and shifts into novel ecosystems.
