The role of mothers in the evolution of immunity. This project will take a fresh approach to studying disease by addressing the role that mothers play in immune system evolution. This project will make a significant contribution to our nation's research capacity and international scientific reputation, by delivering cutting-edge scientific results that resolve outstanding questions in evolutionary biology.
Tracking moving targets: dynamic foraging in ants and slime moulds. This project will investigate how two self-organised systems, ants and slime moulds, deal with dynamic problems. Understanding how both organisms adapt to changes in their foraging environment will increase our knowledge of how self-organised systems function in both biological contexts and in human designed systems.
Not lost in translation: how to get information from other species' calls? Information reduces life's uncertainties, and so underlies adaptive decisions in a changing world. However, the importance of information gained from other species is largely overlooked, despite the flow of information, just like resources, affecting individual fitness and population viability. This project aims to use a novel integration of visual and acoustic ecology to test how animals gain reliable information about p ....Not lost in translation: how to get information from other species' calls? Information reduces life's uncertainties, and so underlies adaptive decisions in a changing world. However, the importance of information gained from other species is largely overlooked, despite the flow of information, just like resources, affecting individual fitness and population viability. This project aims to use a novel integration of visual and acoustic ecology to test how animals gain reliable information about predators by eavesdropping on the alarm calls of other species. Thus, the project focuses on alarm calls because information about danger is critical to animal survival. The outcomes of the project could help us to understand how natural information webs form and function, and so refine predictions about the impact of environmental change on animal communities.Read moreRead less
Gender bender': the impact of endocrine disrupting pollutants on sexual selection. Research into the impacts of pollution on animal reproductive behaviour is crucial if we are to understand species' capacity to adapt to rapidly changing environments, particularly to those that are subject to the impact of human activity. The outcomes of this study will be an important step in learning how to improve the management of biodiversity.
Wildlife responses to endocrine disruptors. This project aims to uncover how a ubiquitous agricultural endocrine disruptor affects development, survival and reproduction in frogs. Widespread pollution by endocrine disrupting chemicals poses a serious threat to wildlife, human health, and the environment. This project will integrate laboratory- and field-based experiments to provide insights into how aquatic contamination by endocrine disruptors can affect vulnerable early life stages and, in tur ....Wildlife responses to endocrine disruptors. This project aims to uncover how a ubiquitous agricultural endocrine disruptor affects development, survival and reproduction in frogs. Widespread pollution by endocrine disrupting chemicals poses a serious threat to wildlife, human health, and the environment. This project will integrate laboratory- and field-based experiments to provide insights into how aquatic contamination by endocrine disruptors can affect vulnerable early life stages and, in turn, adult performance and reproduction. The findings will add significantly to understanding the impact of chemical pollution on wildlife responses to human altered environments.Read moreRead less
Behaviour and evolutionary responses to pharmaceutical pollution. This project aims to uncover how a ubiquitous pharmaceutical pollutant – fluoxetine, known as Prozac – alters the course of reproduction and sexual selection in a freshwater fish. Drugs used in human and veterinary medicine enter the environment and pose a serious threat to wildlife. The project plans to integrate morphological, behavioural, and experimental evolution approaches to yield insights into how fluoxetine affects sexual ....Behaviour and evolutionary responses to pharmaceutical pollution. This project aims to uncover how a ubiquitous pharmaceutical pollutant – fluoxetine, known as Prozac – alters the course of reproduction and sexual selection in a freshwater fish. Drugs used in human and veterinary medicine enter the environment and pose a serious threat to wildlife. The project plans to integrate morphological, behavioural, and experimental evolution approaches to yield insights into how fluoxetine affects sexual traits and behaviours, and how this in turn can affect offspring viability and the evolutionary process. Findings are expected to add to our understanding of how species respond to rapidly changing environments, with consequences for the persistence of populations and the survival of species in the wild.Read moreRead less
Immune defense, disease and damage control in the wild. Immune defences are vital for resistance against infections, but are an overlooked component of disease dynamics in the wild. The project aims to use a model system of long-term studied wild birds to investigate causes of individual variation in innate immunity, the critical first-line-of-defence against new infections. The results may show how immune dynamics are linked to disease, aging, reproduction and longevity and to what extent this ....Immune defense, disease and damage control in the wild. Immune defences are vital for resistance against infections, but are an overlooked component of disease dynamics in the wild. The project aims to use a model system of long-term studied wild birds to investigate causes of individual variation in innate immunity, the critical first-line-of-defence against new infections. The results may show how immune dynamics are linked to disease, aging, reproduction and longevity and to what extent this is environmentally-determined or inherited (its adaptive potential). The outcomes could provide broadly generalizable insights into interactions between the immune system and the environment, and may identify risk factors for vulnerability to novel infectious diseases.Read moreRead less
Lucky in Love: the role of chance in sexual selection. Is luck important in the lives of animals? This project aims to ascertain how much variation in male mating success is attributable to male quality, traits or resources and how much is attributable to luck. Mating is the most important evolutionary process. Male mating success should be highly predictable: males with the best genes, most preferred displays or highest quality resources should attract females. Male mating success is, however, ....Lucky in Love: the role of chance in sexual selection. Is luck important in the lives of animals? This project aims to ascertain how much variation in male mating success is attributable to male quality, traits or resources and how much is attributable to luck. Mating is the most important evolutionary process. Male mating success should be highly predictable: males with the best genes, most preferred displays or highest quality resources should attract females. Male mating success is, however, surprisingly difficult to predict and we currently write off up to 90 per cent of the variance as noise. This project aims to quantify the relative importance of deterministic and stochastic sources of variation in male mating success. Ignored variance may be an untapped opportunity to understand selection.Read moreRead less
Population divergence and the thermal ecology of sexual conflict. This project aims to test how populations of introduced mosquitofish have adapted to local differences in water temperature (such as Tasmania versus Queensland). To what extent has natural selection (for survival) and sexual selection (the ability of males to acquire mates and/or females to resist unwanted matings) driven the local adaptation of populations? Many species have traits that evolve under intense sexual conflict – nota ....Population divergence and the thermal ecology of sexual conflict. This project aims to test how populations of introduced mosquitofish have adapted to local differences in water temperature (such as Tasmania versus Queensland). To what extent has natural selection (for survival) and sexual selection (the ability of males to acquire mates and/or females to resist unwanted matings) driven the local adaptation of populations? Many species have traits that evolve under intense sexual conflict – notably when males harass or coerce females into mating and females resist these attempts. It is assumed that sexual conflict traits are rarely affected by the local environment. The project will test the hypothesis that temperature can actually drive the evolution of such traits, specifically coercion and resistance to mating.Read moreRead less
The evolutionary biology of seminal fluid. This project will identify proteins within seminal fluid that impact sperm performance and male fertility. The work will derive new insights into the evolution of seminal fluid proteins, while simultaneously exploring how environmental factors such as diet impact male fertility in animals and humans.
