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
Evolutionary impacts of gene interactions in a rapidly changing world. This project aims to understand how gene interactions impact evolution in our warming marine environments. The role of gene interactions is controversial because they are assumed to have little effect on genetic variation for fitness in natural populations. Yet new data show that this effect can be substantial and is enhanced by heat stress, explaining most of the genetic variation available for evolution under stressful cond ....Evolutionary impacts of gene interactions in a rapidly changing world. This project aims to understand how gene interactions impact evolution in our warming marine environments. The role of gene interactions is controversial because they are assumed to have little effect on genetic variation for fitness in natural populations. Yet new data show that this effect can be substantial and is enhanced by heat stress, explaining most of the genetic variation available for evolution under stressful conditions. The project aims to use quantitative genetics, genomics, and theory to determine the evolutionary impacts on marine populations facing rapid ocean warming in southeast Australia. The outcomes could change how we view gene interactions, and help us to better predict biological responses to environmental change.Read moreRead less
How does climate affect regeneration and distribution of Australian plants? This project aims to quantify the degree to which Australian plant species have responded to changes in climate over the last few decades, and to build understanding of the mechanisms that underpin responses to climate change. It seeks to fill critical knowledge gaps about the way heatwaves, freezing temperatures and temperature variability affect plants. The project aims to introduce a novel approach that will allow ass ....How does climate affect regeneration and distribution of Australian plants? This project aims to quantify the degree to which Australian plant species have responded to changes in climate over the last few decades, and to build understanding of the mechanisms that underpin responses to climate change. It seeks to fill critical knowledge gaps about the way heatwaves, freezing temperatures and temperature variability affect plants. The project aims to introduce a novel approach that will allow assessment of physiological and morphological change in response to recent climate change in the absence of historic data. Improved accuracy in identifying species that will have trouble responding to climate change would allow managers to more effectively target their resources to maximise biodiversity and ecosystem function.Read moreRead less
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.
How do Microbes Grow in High Salt at Very Cold Temperatures. The proposed research aims to define mechanisms of survival and speciation that underpin the capacity of a novel group of Antarctic microorganisms to evolve dominance in their very cold (-20 degrees Celsius) and very salty environment. Most (~85 per cent) of the Earth's biosphere is cold (<5 degrees Celsius), and yet contains a rich diversity of microorganisms of which we know little. The uniqueness and sensitivity of Antarctica partic ....How do Microbes Grow in High Salt at Very Cold Temperatures. The proposed research aims to define mechanisms of survival and speciation that underpin the capacity of a novel group of Antarctic microorganisms to evolve dominance in their very cold (-20 degrees Celsius) and very salty environment. Most (~85 per cent) of the Earth's biosphere is cold (<5 degrees Celsius), and yet contains a rich diversity of microorganisms of which we know little. The uniqueness and sensitivity of Antarctica particularly demands that we rapidly improve our understanding of its biology. The discoveries made could provide fundamental insight about speciation - processes controlling which life forms that colonise the planet.Read moreRead less
Keeping pace with a changing climate: can Australian plants count on rapid evolution? Integrating field and common-garden experiments with cutting-edge genomic technology, this project will answer the critical question of whether Australia's flora can count on evolution to keep pace with a rapidly changing climate. The project outcomes will inform science-based policies integrating social-economic development and biodiversity conservation.
Mismatch between host-pathogen thermal ecology impacts adaptation to change. This project aims to examine how differences in the thermal performance of hosts and pathogens can influence the capacity of a species to respond to warming temperatures. This project expects to generate new knowledge in the area of global change biology by integrating approaches from the fields of evolutionary genetics, sexual selection, and epidemiology. Expected outcomes include improved knowledge and techniques that ....Mismatch between host-pathogen thermal ecology impacts adaptation to change. This project aims to examine how differences in the thermal performance of hosts and pathogens can influence the capacity of a species to respond to warming temperatures. This project expects to generate new knowledge in the area of global change biology by integrating approaches from the fields of evolutionary genetics, sexual selection, and epidemiology. Expected outcomes include improved knowledge and techniques that can be used to forecast the growth or decline of host and pathogen populations under different scenarios of warming. This should provide significant benefits, such as helping to identify local wildlife or agricultural populations that are most at risk under the duel threat of parasitism and global change.Read moreRead less
Phenotypic plasticity and plant water use in a changing climate: a multi-species, multi-site investigation. Plants are highly responsive to the conditions under which they grow, but the combination of conditions they experience will be altered under climate change. This research into plant responses to the novel environments posed by climate change will examine plasticity in water-use-traits to better predict native plant tolerance of climate change.
