Multicolony tracking reveals potential threats to little auks wintering in the North Atlantic from marine pollution and shrinking sea ice cover
Abstract Aim Extensive development of human activities in combination with ocean warming is rapidly modifying marine habitats in the A rctic and N orth A tlantic regions. To understand the potential impacts on marine biodiversity, there is an urgent need to determine distributions and habitat prefer...

Abstract Aim Extensive development of human activities in combination with ocean warming is rapidly modifying marine habitats in the A rctic and N orth A tlantic regions.
