My research

I am a behavioural ecologist that uses lizards as a model system. I am primarily a field biologist, although increasingly I find myself working with animals in the’ lab’. I have had the good fortune to conduct field work in North America (Texas), South Africa, Mozambique, Zimbabwe, Namibia, Botswana, Kenya, Hawai’i, Sri Lanka, China, Sulawesi and Australia. I work in these three main areas: 1.) animal communication and sexual selection; 2.) cognition; and 3.) understanding social behaviour and the early evolution of sociality in lizards.

In the context of animal communication, my interest lies in the design and information content of animal signals, particularly colour signals, and their role in fitness. For example, we may ask what information a male’s colour signal conveys about their quality to a female or about their competitive ability to a rival male. Similarly, we also work on male chemical signals and their role in sexual selection. Recently, we have been working on colour signals that are naturally selected and which appear to act as a deimatic display to a predator. Deimatic displays are almost completely unstudied in lizards. We have identified potential deimatic displays in independently evolved lizard clades in Africa, Asia and Australia that have high UV reflectance and are working to understand the proximate and ultimate factors that may be driving their convergent evolution. We are also working on the evolution of complex, dynamic tail waving in Australian dragons and Asian toad-headed agamas. In these systems, we are taking a comparative approach to understanding how elements of courtship and display behaviour have evolved as a result of phylogeny and/or environmental factors.

A second theme in my lab is cognition and brain size evolution. We are investigating aspects of cognition such as spatial learning and whether this links to alternate reproductive tactics and personality in water skinks (Eulamprus quoyii). We also ask whether cognitive ability is domain-specific or general. In other words, do lizards that perform well in a one cognitive domain such as a spatial task also perform well in an unrelated cognitive area such as an instrumental task. This is a key question in cognitive ecology. We also study the role of cognition and personality in highly successful invasive species such as wall lizards and cane toads, in which some individuals are more prone to dispersal than others. Another major focus is testing the social intelligence hypothesis for the evolution of large brain size. This is a large-scale project taking a comparative approach to testing whether social factors have driven brain size evolution in the Egernia group. Egernia are a novel system for examining how sociality may have acted on brain size because some species live in multi-generational family groups while others are solitary and they thus represent an alternative to previously studied mammal and bird models.

Finally, we are using the family-dwelling, social Australian Egernia-Liopholis clade as a model system for understanding social plasticity and the origins of family living (in collaboration with Geoff While, University of Tasmania and Tobias Uller and Charlie Cornwallis, Lund). We are interested in understanding what social and environmental conditions drive a species towards family living and co-operation, and just how plastic sociality is. We also have a new project focused on the mechanisms of complex sociality. This work is in collaboration with other research groups in Australia (Geoff While, University of Tasmania) and the US (Dustin Rubenstein, Columbia University; Alex Ophir, Cornell). This work has three main objectives: 1. Understanding how the social environment interacts with the brain; 2. determining the role of neuropeptides in moderating aggression and enhancing pair bonding and social associations; and, 3. understanding the role of maternal care in offspring social development and cognition.

Ultimately, we are interested in investigating the possibility of a general theory for the evolution of vertebrate sociality. Variation in social behaviour and social organisation in lizard systems are therefore of great interest.
