Gail Ashton field research

Biography

Research Interests:

Gail is a marine benthic ecologist focusing on hard substrate communities. Her work spans tropical to polar latitudes in an attempt to understand the effect of anthropogenic impacts on marine communities. Her interests include: the distribution and dispersal of marine invertebrates; factors determining the settlement and establishment of fouling communities; phylogenetic analysis of population distributions and introduction pathways; and the influence of the physical environment on the success of invertebrate species.
