I study changes to the diversity of life in aquatic systems due to invasions and local extinctions. The overarching goal of my research is to improve our ability to predict the risks and consequences of invasions and extinctions. I generally take a bottom up mechanistic approach, determining the role of behavior, physiology, and morphology at the individual level for establishing patterns and processes at the population and community scales. I use a variety of approaches, including field observations, field and laboratory experiments, physiological measurements, and computer simulation modeling. |

-
A new paper in Marine Ecology Progress Series by Toscano and Griffen 2012 examines the role of body size diversity for trophic interactions in oyster reefs.
-
A new paper in the Journal of Animal Ecology by Blaine Griffen and undergrad Hallie Mosblack demonstrates how crab gut size can be used to predict diet composition both within and across species. (Click here here for more details)

A new paper in the Journal of Experimental Marine Biology and Ecology by Griffen et al. 2011
demonstrates the physiological mechanism underlying species replacement with the arrival of an invasive crab on New England shores. (Click here for details)
