Rapid worldwide depletion of predatory fish communities
Serious concerns have been raised about the ecological effects of industrialized fishing, spurring a United Nations resolution on restoring fisheries and marine ecosystems to healthy levels. However,Expand

Response to Comments on "Impacts of Biodiversity Loss on Ocean Ecosystem Services"
We show that globally declining fisheries catch trends cannot be explained by random processes and are consistent with declining stock abundance trends. Future projections are inherently uncertainExpand

Predicting ecological consequences of marine top predator declines.
Recent studies document unprecedented declines in marine top predators that can initiate trophic cascades. Predicting the wider ecological consequences of these declines requires understanding howExpand
