seals given leg up

Male seals are reaping the benefits of climate change by having more sex, scientists have discovered. Subordinate grey seals are taking advantage of rising temperatures and falling rainfall to mate more often.

Due to climate change female grey seals are being forced to travel further for drinking water – removing them from the watchful eye of the dominant males and allowing the subordinate males to take advantage.

The research has been conducted by Dr Sean Twiss, from Durham University, who studied the mating patterns of grey seal colony on the remote Scottish Island of North Rona.

“These findings show that climate change, whilst endangering many species, could also help to increase the genetic diversity of some species, giving a leg up (or over!) to males who normally wouldn’t be so successful.”
