Study provides insights into how cold-adapted species respond to climate change

By analyzing historical data generated during and between ice ages, researchers have identified several mechanisms used by cold-adapted Arctic mammal species to respond to severe climate changes.

As described in a study published in Mammal Review, the team formulated three models to help interpret the responses of different species to such climate cycles. The models bring new insight into how cold-adapted species respond to anthropogenic global warming, which is important for decision-making to improve biodiversity and habitat conservation.

“Today, Arctic species suffer the most from global warming and without a doubt humans are responsible for this trend. We can’t go back, but hopefully we can still prevent the next mass extinction. And the best start is to understand how climate warming affect Arctic taxa,” says corresponding author Joanna Stojak, Ph.D., of the Mammal Research Institute of the Polish Academy of Sciences. “We took a closer look at the past and present changes in the genetic diversity of different cold-adapted species and how their ranges changed along with the changing climate. It was very exciting to see different taxa responding differently, Yet we were able to identify clear and common patterns.”
