Shifting the life-history paradigm: discovery of novel habitat use by hawksbill turtles.

abstract：:A recent study showed that a critically endangered migratory predator species, the Balearic shearwater Puffinus mauretanicus, rapidly expanded northwards in northeast Atlantic waters after the mid-1990s. As a significant positive correlation was found between the long-term changes in the abundance of this seabird and ...
