Understanding the impact of heat stress on cognition in a changing world. Our research will determine how anthropogenic climate change effects the ability of animals to process information in their environment. This research is significant because it directly addresses the growing issue of wildlife adaptation to climate change. If heat stress, reported widely in wildlife both in Australia and globally, impairs an animal's ability to respond to stimuli in its surrounding environment, then this ma ....Understanding the impact of heat stress on cognition in a changing world. Our research will determine how anthropogenic climate change effects the ability of animals to process information in their environment. This research is significant because it directly addresses the growing issue of wildlife adaptation to climate change. If heat stress, reported widely in wildlife both in Australia and globally, impairs an animal's ability to respond to stimuli in its surrounding environment, then this may cause lower reproductive success (eg lower predator detection rates) and population declines. We aim to identify critical temperature points beyond which the cognitive responses of animals decline rapidly - a significant finding for effective wildlife management priorities in the face of rapid climate change.

Summary
Controls on the severity of past environmental crises. This project aims to investigate how the rate of volcanic volatile emissions controlled the severity of past environmental crises. Catastrophic mass extinctions and major oceanic anoxia events are principally caused by the emplacement of gigantic volcanic eruptions but the volume of magma does not correlate with environmental severity. This project couples high-precision age and volatile emission measurements to model distinct climatic pertu ....Controls on the severity of past environmental crises. This project aims to investigate how the rate of volcanic volatile emissions controlled the severity of past environmental crises. Catastrophic mass extinctions and major oceanic anoxia events are principally caused by the emplacement of gigantic volcanic eruptions but the volume of magma does not correlate with environmental severity. This project couples high-precision age and volatile emission measurements to model distinct climatic perturbations over Earth’s last 540 million years. The intended outcome is to find a root cause for severity of past environmental crises, with past emission rates to be used as tools to model possible future climatic crises and provide a new fundamental understanding of Earth’s magmatic engine.Read moreRead less
Revealing the impacts of super-charged photosynthesis on leaf respiration. This project aims to use state-of-the-art technologies to develop a novel framework that links a super-charged version of photosynthesis (known as C4 photosynthesis) to changes in nocturnal leaf respiration. A quarter of global land photosynthesis occurs in C4 plants that include several important cereal crops. Although advances have been made in modelling C4 photosynthesis, these advances are unable to model variations i ....Revealing the impacts of super-charged photosynthesis on leaf respiration. This project aims to use state-of-the-art technologies to develop a novel framework that links a super-charged version of photosynthesis (known as C4 photosynthesis) to changes in nocturnal leaf respiration. A quarter of global land photosynthesis occurs in C4 plants that include several important cereal crops. Although advances have been made in modelling C4 photosynthesis, these advances are unable to model variations in nocturnal respiration. Expected outcomes include equations that predict respiration in C4 plants growing in current/future climates. Benefits to include knowledge needed to engineer faster-growing crops and providing climate modelers the ability to more accurately predict carbon exchange in C4-dominated ecosystems.

Identifying potential trade-offs of adapting to climate change. Climate change and marine heatwaves introduce strong, directional selection for heat tolerance which, in turn, alters the genetic composition and diversity of marine species. While this may facilitate adaptation to warmer conditions, reduced genetic diversity may limit resilience or cause maladaptation to additional stressors. This project will focus on habitat-forming kelps and will aim to both assess the negative consequences of r ....Identifying potential trade-offs of adapting to climate change. Climate change and marine heatwaves introduce strong, directional selection for heat tolerance which, in turn, alters the genetic composition and diversity of marine species. While this may facilitate adaptation to warmer conditions, reduced genetic diversity may limit resilience or cause maladaptation to additional stressors. This project will focus on habitat-forming kelps and will aim to both assess the negative consequences of rapid selection and to disentangle the mechanisms of climate adaptation. Through a powerful combination of controlled experiments on known genotypes and cutting-edge transcriptomic approaches, this project will transform our understanding of the adaptability of foundation species in a rapidly changing ocean.

Marine heatwaves drive loss of genetic diversity and selection in kelps. This project aims to unravel where and when marine heatwaves drive loss of genetic diversity and rapid directional selection in kelp forests. Although the devastating ecological impacts of marine heatwaves are well studied, empirical understanding of how marine heatwaves impact underlying evolutionary processes including adaptive capacity and resilience is lacking. This research will use a powerful combination of innovative ....Marine heatwaves drive loss of genetic diversity and selection in kelps. This project aims to unravel where and when marine heatwaves drive loss of genetic diversity and rapid directional selection in kelp forests. Although the devastating ecological impacts of marine heatwaves are well studied, empirical understanding of how marine heatwaves impact underlying evolutionary processes including adaptive capacity and resilience is lacking. This research will use a powerful combination of innovative heatwave analyses, cutting-edge genomics and physiological experiments to fill these knowledge gaps and represents a step change in our understanding of how kelp respond and adapt in multi-stressor seascapes. Results will pave the way for development of novel mitigation strategies to future-proof marine management. Read moreRead less

Resilience of forest ecosystems to multiple stressors in a changing climate. This project will examine the influence of multiple stressors including disease, drought and fire, on the resilience of forest ecosystems within Australia. This project expects to generate new knowledge for land managers and the international community, in management of forest health by determining how soil health and soil fungi influence forest recovery after disturbance events. Anticipated outcomes include improved ri ....Resilience of forest ecosystems to multiple stressors in a changing climate. This project will examine the influence of multiple stressors including disease, drought and fire, on the resilience of forest ecosystems within Australia. This project expects to generate new knowledge for land managers and the international community, in management of forest health by determining how soil health and soil fungi influence forest recovery after disturbance events. Anticipated outcomes include improved risk assessment of disturbed forests to future disturbances and significant benefits will include informing climate smart management goals in the recovery of important forest ecosystems, not only for the forest tree species but the animal, plant, insect and microbe communities that depend on these systems.Read moreRead less
