Alexandra RaveloPh.D. Student

Marine Biology

Thesis Title

Epibenthic community patterns on the Alaska Arctic shelves, environmental drivers of community variability and dominant brittle star population dynamics

Career Goals

My main interests relate to community ecology, biodiversity and population dynamics of marine fauna. I have a strong interest in understanding changes in marine community patterns over time and space on shelf and near-shore systems.

Research Overview

My research is focused on how the epibenthic invertebrate communities vary spatially. Specifically, how the combination of the species life history and the different environmental factors may be determining the pattern of species distribution, total epibenthic abundance, biomass and diversity indices throughout large spatial scales. I'm also interested in linking the long term changes in sea ice cover with benthic community patterns and biomass of dominant benthic taxa.
