Applying portfolio effects to the Gulf of Alaska ecosystem: Did multi-scale diversity buffer against the Exxon Valdez oil spill?

Principal Investigators:

Kristin N. Marshall, Anne H Beaudreau, Richard E. Brenner, Mary E. Hunsicker, Andrew O. Shelton, and Eric J. Ward

Understanding how ecosystems respond to environmental perturbations has been a central problem in ecology since its inception. As anthropogenic impacts increase globally, so does the difficulty of disentangling “natural” variability from human-caused events. Marine ecosystems, in particular, are subject to continuous anthropogenic disturbance (e.g. fishing pressure) and the risks of human-induced environmental disasters, as well as environmental variation. Biodiversity and variation in species responses to climate and other factors may confer... more
