Current Project

Ecological dynamics at biogeographic transition zones

Ecosystems at the transition of biogeographical zones are projected to undergo multidimensional changes through altered patterns of survivorship and dispersal and shifts in the distribution and abundances of species, many of which are at the margins of their biogeographic ranges and environmental tolerances. The subtropical-to-temperate transition zones in eastern Australia and Japan harbour a unique combination of tropical, subtropical and temperate taxa, including corals at their high-latitude range limits. Primarily non-reefal coral communities occur in pockets of suitable habitat and extend to high latitudes. They are regarded as potential refuge habitats for tropical species as they become threatened by global warming, however increased ecological understanding of the mechanism that structure them is required before these and similar questions can be properly assessed. My research aims to address some of these knowledge gaps. I use a combination of primary data collection, trait-based, phylogenetic community ecology and statistical modelling approaches to investigate ecological dynamics at biogeographic transition zones in Australia and Japan.
