Killer whales are expanding their territory and have moved into Arctic waters as climate change melts sea ice, with two genetically distinct populations being identified by Canadian scientists.

The study says the orcas could also affect humans, by "adding top-down pressure on Arctic food webs crucial to northern communities' social and economic well-being." It says killer whales in the ...

Killer whales are expanding their territory and have moved into Arctic waters as climate change melts sea ice, with two genetically distinct populations being identified by Canadian scientists.

The study claims that the Arctic is the fastest warming region on the planet and that, as sea ice retreats, its waters are becoming the ideal habitat for traditionally subarctic species such as killer ...
