Research

My current research in collaboration with Prof. Marti Anderson aims to understand the role of evolutionary processes in determining spatial variation in the composition of New Zealand fish communities.

Patterns of biodiversity are generated via evolutionary and ecological processes, yet these two processes are often considered in isolation. In community ecology, species are typically treated as equivalent units of biodiversity, without reference to shared and derived evolutionary histories. However, the phylogentic relationships among constituent species can provide a temporal context for species turnover among communities; whether they be ‘basal’ in the phylogenetic tree or ‘terminal’. Hence, community phylogenies can help us to understand the roles of neutral processes (e.g. regional history and dispersal) and deterministic processes in influencing community composition and species turnover. I have been awarded an Allan Wilson Centre Postdoctoral Fellowship to work with Profs. Marti Anderson and Paul Rainey to use a phylogeny of New Zealand fishes to help us understand patterns in fish community composition across latitudinal and depth gradients.

More broadly my research has two main themes:
1) macroecology/evolution - including the synthesis of multi-species genetic datasets, biogeography, and community ecology.
2) population demographics and genetics - including the roles of migration (connectivity), and local selection in population persistence.
