Harbour porpoises respond to climate change

摘要: The effects of climate change on marine ecosystems and in particular top predators are difficult to assess due to, among other things, spatial variability, lack clear delineation habitats. banks West Greenland located a sensitive area likely elicit pronounced responses oceanographic changes the North Atlantic. recent increase sea temperatures has had cascading ice coverage, residency predators, abundance important prey species like Atlantic cod (Gadus morhua). Here, we report response one Greenland; harbour porpoise (Phocoena phocoena). porpoises depend locating high densities with nutritive value they have apparently responded general warming by longer residence times, increased consumption resulting improved body condition form larger fat deposits blubber, compared situation during cold period 1990s. This is few examples measurable effect mammal population.
