The evolution of host-parasite interactions during a biological invasion. This project aims to elucidate how host organisms and their parasites adapt to each other, exploiting the fact that a biological invasion imposes novel evolutionary challenges. This project expects to generate new knowledge about how the interaction between host and parasite species is affected when the system is exposed to powerful new selective forces. Expected outcomes of this project include development of theory, trai ....The evolution of host-parasite interactions during a biological invasion. This project aims to elucidate how host organisms and their parasites adapt to each other, exploiting the fact that a biological invasion imposes novel evolutionary challenges. This project expects to generate new knowledge about how the interaction between host and parasite species is affected when the system is exposed to powerful new selective forces. Expected outcomes of this project include development of theory, training of students in an emerging field, and a nuanced understanding of this important topic. This should provide significant benefits, such as an enhanced ability for wildlife managers to predict the impact of parasites on species of wildlife that are extending their geographic ranges.Read moreRead less

Summary
Using biological invasions to understand evolutionary processes. The invasion of cane toads through Australia has been devastating for many native species, but created opportunities for others. The rapid evolutionary responses stimulated by toad invasion provide a uniquely powerful model system with which to explore the broader question of how species adapt to novel challenges.

Summary
Re-evaluating evolution by examining developmental plasticity in response to the social environment. Our understanding of trait evolution is derived from our assumption that traits are a signal of male quality as they are costly to produce. The project will integrate this concept with a new theory stating that males shift their development to exploit the weaknesses of rivals; thereby leading to a more holistic understanding of evolution.

Summary
More than meets the egg: environmental effects on sperm quality, sperm competitive success, and offspring fitness. Can a male's environment affect his sperm quality and the health of his offspring? By experimentally testing how the paternal environment affects sperm quality, this project will help us understand (1) why sperm vary so much, and (2) what consequences variability in sperm quality has for paternity success and offspring fitness.
Evolution of maternal effects: a life-history perspective. The community benefits from the present project are two-fold. Firstly, it strengthens Australia's competititve position in evolutionary biology research, and its applications in conservation and medicine. The projects focus on long-term consequences of early developmental conditions is considered to be a priority in both medical and evolutionary research. Secondly, understanding variation in phenotypic traits in relation to environmental ....Evolution of maternal effects: a life-history perspective.

Firstly, it strengthens Australia's competititve position in evolutionary biology research, and its applications in conservation and medicine. The projects focus on long-term consequences of early developmental conditions is considered to be a priority in both medical and evolutionary research. Secondly, understanding variation in phenotypic traits in relation to environmental factors, such as prenatal stress, is important for designing conservation and animal breeding programs to minimize the risk of population decline and to ensure uncompromised husbandry conditions to avoid animal suffering.

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 Impact of Water Stress on Early Humans in the Kalahari Desert. This project aims to understand the impacts of water stressed environments for early modern human behaviour through state-of-the-art excavation techniques and palaeoenvironmental reconstruction at two new archaeological sites in the Kalahari. How humans mitigated water stress during a major technological transition is significant because adaptability to arid environments was crucial for humans expanding beyond Africa and into Aus ....The Impact of Water Stress on Early Humans in the Kalahari Desert. This project aims to understand the impacts of water stressed environments for early modern human behaviour through state-of-the-art excavation techniques and palaeoenvironmental reconstruction at two new archaeological sites in the Kalahari. How humans mitigated water stress during a major technological transition is significant because adaptability to arid environments was crucial for humans expanding beyond Africa and into Australia. The expected outcome of this project is creation of new knowledge on the origins of human resilience to water stress. The benefit lies in the potential to gain insights into meeting future climate challenges by exploring the adaptive strategies developed by early modern humans in the southern Kalahari.Read moreRead less

As the oceans simultaneously warm and acidify, prospects for marine biota are of concern. This project aims to determine the potential for phenotypic adjustment and evolutionary adaptation. To discern the roles of phenotype and genotype in marine invertebrate stress tolerance this project endeavours to use selection experiments, long-term rearing and quantitative genetics . A focus on vulnerable calcification systems could determine genetic mechanisms underlying impaired growth. Investigation of species from the east Australia latitudinal thermal gradient, a global change hot spot could generate insights into biological responses and adaptive potential in a changing ocean and on time scales relevant to resource managers to understand the challenges faced by marine biota.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.

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
Dimensions of ecological strategy for plants. A more fundamental understanding will be sought about the architecture and ecology of vegetation and why it varies around the world. Under a high- CO2 future, models will be needed that operate through fundamental mechanisms of evolution, competition and physiology, rather than through extrapolation from present-day plants.
