Assessing the ecological costs and benefits of artificial wetlands in urban landscapes. The nature and distribution of wetlands around cities is changing at an unprecedented rate, with artificial wetlands increasingly dominating urban landscapes. The consequences of these changes for animals, however, are largely unknown. Some artificial wetlands may be poor quality habitats that pose considerable risks to urban biodiversity, while others may play an important role in conservation.

The nature and distribution of wetlands around cities is changing at an unprecedented rate, with artificial wetlands increasingly dominating urban landscapes. The consequences of these changes for animals, however, are largely unknown. Some artificial wetlands may be poor quality habitats that pose considerable risks to urban biodiversity, while others may play an important role in conservation. The project aims to examine the ecological costs and benefits of artificial wetlands for native animals, and provide guidelines to help ensure wetland construction and management is cost effective and maximises biodiversity outcomes.Read moreRead less

Backyard bandicoots: Engaging community in urban bushland conservation. This project aims to develop a model for urban ecosystem function and restoration, by identifying resources used by urban bandicoots (quenda). Digging mammal species turn over substantial volumes of soil as they forage for invertebrates, subterranean fungi, and plant material. These ecosystem engineers contribute to water infiltration, nutrient cycling, increased soil microorganism function, and seedling recruitment. They spread hypogeous mycorrhizal fungi that contribute to plant nutrition, crucial in Australia's nutrient-poor soils. This research is expected to improve targeted plantings in bushland reserves, and identify and mitigate threats to bandicoots in cities.Read moreRead less
Discovering how termites use vibrations to make foraging decisions. Termites are pests affecting one third of Australian homes. The annual cost of treatment and damage repair is over $20 billion worldwide. Yet, little is known about how termites make foraging decisions based on vibrations. This project will study the key features in vibration signals produced by termites to unlock the secrets of their foraging behaviour.

This project will provide answers to fundamental questions in evolutionary biology while identifying diet compositions that will benefit human health and well-being. Using a longitudinal public-health database, the Raine Study, and a theoretical framework from the field of Nutritional Ecology, the project will provide new knowledge on how nutrition affects key life-history traits in humans including immune function, reproductive health, physical appearance, and healthy ageing. A systematic literature review on how diet impacts these life-history traits in animals generally, and an experimental study of the effect of diet on health and reproduction in the house mouse (a lab analog species for humans) will complement the Raine Study findings.Read moreRead less
Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project wi ....Linking individual traits, the gut microbiome and parasite load in wildlife. This project aims to apply principles of community ecology to the gut microbiome of an urban exploiter – the common brushtail possum - to reveal how animal traits influence individual variation in the load of gut parasites that cause disease in both humans and wildlife. By combining assays defining the behavioural and physiological states of individuals with sophisticated analyses of their gut microbiome, our project will provide a new, yet crucial, perspective on how and why diseases spread. Our discoveries will help understand and manage the burden of infectious diseases from parasites in and beyond our cities and across the human-wildlife interface; essential for improving human and wildlife health in an increasingly urbanised Australia.Read moreRead less
Contemporary ecological threats from historical pollution events and their modification by environmental conditions. Many Australian ports have contaminated sediments that are a legacy of industrial pollution. The resuspension of these sediments through shipping or dredging activity represents an obvious, yet unsubstantiated, threat to the biodiversity and health of marine communities living well above the seafloor. This research proposal addresses a strategic knowledge gap with implications for ....Contemporary ecological threats from historical pollution events and their modification by environmental conditions. Many Australian ports have contaminated sediments that are a legacy of industrial pollution. The resuspension of these sediments through shipping or dredging activity represents an obvious, yet unsubstantiated, threat to the biodiversity and health of marine communities living well above the seafloor. This research proposal addresses a strategic knowledge gap with implications for appropriate management of port operations. Identifying the conditions under which contaminated sediments may cause an impact, and the environmental factors that modify these effects, will produce significant advances in scientific understanding and the results will be of strategic interest to all Australian Port Authorities.

The benefits of sociality: understanding the relationship between cooperation, cognition and fitness. Cooperation may present unique cognitive challenges. Individuals perform behaviours that provide fitness benefits to others, exposing themselves to risk. The need to monitor the behaviour of group members, recognise suitable cooperative partners, and make corresponding behavioural adjustments to maximize the benefits of cooperation, may therefore be an important driver of social evolution. The r ....The benefits of sociality: understanding the relationship between cooperation, cognition and fitness. Cooperation may present unique cognitive challenges. Individuals perform behaviours that provide fitness benefits to others, exposing themselves to risk. The need to monitor the behaviour of group members, recognise suitable cooperative partners, and make corresponding behavioural adjustments to maximize the benefits of cooperation, may therefore be an important driver of social evolution. The relevance of understanding the relationship between cognition and cooperation is in how it affects the fitness of individuals and the stability of cooperation. This project aims to unveil this relationship by conducting one of the first comprehensive studies of the selective benefits of cognitive ability in a wild, cooperative bird species.Read moreRead less
Physiological effects of extreme hot weather on animals’ metabolism, development, body size and cell lifespan. This project aims to determine the physiological effects of extreme hot weather on animals’ metabolism, development, body size and cell lifespan. Body size in animals is negatively related to latitude; individuals are relatively small in hot climates. The project will test the idea that the adverse effects of heat during development constrain body size.

This project aims to determine the physiological effects of extreme hot weather on animals’ metabolism, development, body size and cell lifespan. Body size in animals is negatively related to latitude; individuals are relatively small in hot climates. The project will test the idea that the adverse effects of heat during development constrain body size. The project will draw on physiology, endocrinology, behaviour and cell biology and study birds across Australian climates and in a temperature-controlled laboratory. The outcomes of the project will provide insight into regional variation in species vulnerabilities to climate variation and inform biodiversity management.Read moreRead less

Heatwaves are increasing in frequency and intensity, and extreme heat poses a significant threat to tree growth and survival. This project aims to investigate how different Australian tree species respond to extreme heat by tracking dynamic changes in water use during both natural and experimental heatwaves, representing current and future stress levels. Identification of a predictable response among plant functional types could be used to better forecast the potential effects of climate change on forest ecosystems. This project also expects to identify heat-tolerant tree species and their relevant physiological traits, which can improve the success of urban tree plantings to help create cooler, greener cities throughout Australia.Read moreRead less
The origins of gender. This project intends to address how the evolutionary phenomena of intra-sexual competition and inter-sexual conflict interact with economic circumstances to shape gendered behaviour and attitudes. These phenomena are important in evolution, economics, psychology and sociology, with implications for the economy and for the welfare of women and men.

This project intends to address how the evolutionary phenomena of intra-sexual competition and inter-sexual conflict interact with economic circumstances to shape gendered behaviour and attitudes. These phenomena are important in evolution, economics, psychology and sociology, with implications for the economy and for the welfare of women and men. The project predicts that gender-related culture arises, partially, out of mating market dynamics. The research crosses traditional boundaries between biology and economics to investigate the forces giving rise to gendered behaviour and resulting patterns of marriages, violence, political preferences and occupational choices. The project may provide new insights into the links between gender and violence, within-family conflicts, and gender roles in the home and workplace.Read moreRead less
