Ecological investigations in evolution, conservation and populations.

My research centres on ecological investigations incorporating a wide range of techniques to address hypotheses in evolution, conservation and population biology. My research integrates multiple areas of biology such as morphology, functional ecology, population genetics and behaviour. 

Africa’s herpetofauna (amphibians and reptiles) have many diverse body forms, which correspond with different abilities of individuals to disperse resulting in differences in gene flow between populations. Long-term ramifications of this mean that highly philopatric species (such as caecilians and chameleons) can easily become isolated, speciating, and increasing local levels of biodiversity with important consequences for their conservation. Barriers to gene flow will not be equal to all taxa, and may arise as a result of ancient vicariance or anthropogenic habitat fragmentation. On the other hand, cosmopolitan species are often able to disperse across many potential barriers resulting in large panmictic populations. My interests relate to how changes in body forms of result in different gene flow between populations across such ancient and modern barriers. I integrate a synergy of techniques including morphology, genetics and performance to address a whole range of evolutionary, conservation and population issues in ecology.
