Summary
Mechanisms influencing the evolutionary trajectories of extended phenotypes. Although we know how the environment and predator-prey interactions shape traits, we have a poor grasp of the evolution of extended phenotypes. The webs of spiders have switched repeatedly between two- and three-dimensional forms over time, so are excellent models for assessing extended phenotype evolution. This project will use innovative experiments to assess whether the prey capture performance of webs or their visib ....Mechanisms influencing the evolutionary trajectories of extended phenotypes.

From individual interactions to global patterns: understanding the basis of collective behaviour. Some of the most incredible sights in nature happen when animals form into groups, such as shoals or flocks. This study examines the phenomenon of collective animal behaviour to understand how simple interactions between group members scale to produce these behavioural spectacles.
The danger within: assessing the threats to an endangered finch from genetic incompatibility, limited dispersal and effective population size. The Gouldian finch has declined dramatically over the past half century and remains one of Australia's most threatened birds. This project will use some cutting edge genetic techniques to understand some of the processes that undermine the species' recovery and our ability to monitor current populations.

Summary
Early environmental effects on phenotypic development and evolution. Early developmental environments can profoundly influence the survival and reproductive success of organisms, including humans. The project aims to use an exceptional model lizard system to test a new theory about how personality and learning are influenced through the manipulation of offspring environment and how this affects lifetime fitness. Understanding these effects is important for predicting the responses to selection i ....Early environmental effects on phenotypic development and evolution. Early developmental environments can profoundly influence the survival and reproductive success of organisms, including humans. The project aims to use an exceptional model lizard system to test a new theory about how personality and learning are influenced through the manipulation of offspring environment and how this affects lifetime fitness. Understanding these effects is important for predicting the responses to selection imposed by changing environments, the success of re-introduction programs for threatened species, and for understanding the long-term viability of populations. This project aims to merge theoretical developments in life history theory and evolutionary biology and contribute important empirical advances to a new research field.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. The project will draw on physiolo ....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. 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
