Dr. Steven Trewick is currently working as a Professor in Evolutionary Ecology in the Department of Agriculture and Environment, Massey University , New Zealand.
The NZ archipelago has ancient geological links with other (Gondwanan) landmasses, and harbours some organisms of ancient pedigree, but many taxa appear to be the products of recent colonisation or radiation. I am interested in the use of ecological and molecular approaches to help understand the process that lead to the distributions and interactions of species. I am particularly interested in endemic invertebrates including peripatus, weta, carabid beetles and stick insects. Studies of these taxa involve comparison with relatives in neighbouring regions (Australia, New Caledonia etc). I also work on birds, exploring evolution of flightlessness and endemism more generally.
