TL;DR: This article developed an ecosystem-specific, multiscale spatial model to synthesize 17 global data sets of anthropogenic drivers of ecological change for 20 marine ecosystems and found that no area is unaffected by human influence and that a large fraction (41%) is strongly affected by multiple drivers.
Journal ArticleDOI
The Ecology of Seabird Feeding Flocks in Alaska
TL;DR: Hoffman et al. as discussed by the authors classified seabird feeding flocks into three types on the bases of flock size and longevity and the nature of the food source: small, short-lived flocks over tightly clumped prey are called Type I; larger (5,000+ individuals), longer-lasting flock over less tightly clumping and less reactive prey is called Type II; Type III flocks form where zooplankton and other organisms are concentrated by downwelling.
Journal ArticleDOI

TL;DR: In this paper, the authors treat MPAs as "policy experiments" and employ the tools of impact evaluation as a way for policy-relevant science to inform and advance science-based MPAs policy.
Journal ArticleDOI
Distributions and predator-prey interactions of macaroni penguins, Antarctic fur seals, and Antarctic krill near Bird Island, South Georgia
TL;DR: The relationships between the distributions of predators and their prey with respect to the abundance of krill in the water column and marine habitats near the colonies showed positive correlations with Antarctic krill density across a wide range of spatial scales.
