Reproductive plasticity and climate change: insights from a region of opportunistic birds. Understanding how animal species respond behaviourally and physiologically to climatic variability is key to predicting how they will adapt to a changing climate. Australasia is home to a number of native and introduced species that breed across a range of climates and seasons. This project will establish collaborative infrastructure and a research network to systematically study and identify the constrain ....Reproductive plasticity and climate change: insights from a region of opportunistic birds. Understanding how animal species respond behaviourally and physiologically to climatic variability is key to predicting how they will adapt to a changing climate. Australasia is home to a number of native and introduced species that breed across a range of climates and seasons. This project will establish collaborative infrastructure and a research network to systematically study and identify the constraints and adaptations that birds have to adjust to a variable climate across Australasia. This large-scale comparative project will provide important insight into the globally observed patterns of reproductive failure and changes in breeding and migration times in birds, which have been related to a changing climate and pose a threat to biodiversity.Read moreRead less
Predicting adaptive responses to climate change in Australian native bees. This project aims to understand how insects will adapt to climate change by examining a largely overlooked but economically important group of species: Australian native bees. Native bees are important pollinators of both crops and native plants, but their sensitivity to changes in climate are unknown. Expected outcomes include new knowledge of the resilience of native bees to climate change, and new effective tools for p ....Predicting adaptive responses to climate change in Australian native bees. This project aims to understand how insects will adapt to climate change by examining a largely overlooked but economically important group of species: Australian native bees. Native bees are important pollinators of both crops and native plants, but their sensitivity to changes in climate are unknown. Expected outcomes include new knowledge of the resilience of native bees to climate change, and new effective tools for predicting climate change resilience that can be applied to many species. The intended benefits include increasing our understanding of the potential for native bees to act as future pollinators in Australia’s natural and agro-ecosystems, and guide policy and management decisions to better protect and conserve our bee fauna.Read moreRead less
The role of epigenetics in conferring resilience to environmental change. This project aims to determine whether epigenetic mechanisms confer resilience to environmental change in natural populations. Understanding epigenetic mechanisms is significant because they can mediate compensatory responses by animals to rapid environmental change. This project intends to link molecular changes to ecological outcomes to determine rapid remodeling of phenotypes to maintain fitness in variable environments ....The role of epigenetics in conferring resilience to environmental change. This project aims to determine whether epigenetic mechanisms confer resilience to environmental change in natural populations. Understanding epigenetic mechanisms is significant because they can mediate compensatory responses by animals to rapid environmental change. This project intends to link molecular changes to ecological outcomes to determine rapid remodeling of phenotypes to maintain fitness in variable environments. The project would benefit Australia’s research capacity and training, and the efficacy of conserving our natural environment.Read moreRead less
Biological bet hedging in a variable ocean. This project aims to investigate how the functioning of photosynthetic plankton changes as they respond to increasing environmental variation, a significant uncertainty in ocean forecasts. The project will advance knowledge about phytoplankton nutrient acquisition strategies in increasingly variable environments. Expected outcomes include improved predictions of ocean ecosystem services. This knowledge will enhance food security, assisting the fisherie ....Biological bet hedging in a variable ocean. This project aims to investigate how the functioning of photosynthetic plankton changes as they respond to increasing environmental variation, a significant uncertainty in ocean forecasts. The project will advance knowledge about phytoplankton nutrient acquisition strategies in increasingly variable environments. Expected outcomes include improved predictions of ocean ecosystem services. This knowledge will enhance food security, assisting the fisheries, aquaculture and environment sector to develop effective adaptation strategies, and thereby safeguard the social and economic wellbeing of the communities that rely on them.Read moreRead less
Were abrupt changes in the Precambrian global carbon cycle the trigger for animal appearance and radiation on Earth? The origin of complex life and the properties that allow that life to be sustained on this planet are recorded within the geologic record. This project will reveal the role that severe perturbations of the global carbon cycle and climate had in triggering the step-wise change to animal life after billions of years of only single cell organisms.

Summary
The battle of the sexes heats up: climate change and the ecological and evolutionary fate of reptiles when sex is determined by temperature. In species where gender (male or female) is determined by temperature early in life, what will happen when climate changes? This project will examine the sex ratios, behaviour and evolutionary potential of a native Australian lizard in relation to climate, addressing a question of global significance and informing management of native species.
Impact of climate change stressors on calcifying and non-calcifying marine life stages: predicting tipping points for persistence in a changing ocean. Australia generates considerable prosperity from its oceans with marine invertebrate resources playing a key role. These resources are at risk due to climate change. This project will study early life stages of key marine species to determine sensitivities to ocean warming and acidification and inform assessment of risk in a changing ocean.
