The parasite takes over the snail's body and mind to turn it into an organism that will attract birds, the parasite's second host. Polar bears are spending more time on land as Arctic ice diminishes, causing them to lose body weight and decline in numbers as they are unable to hunt for favored prey such as seals. Mother bears are also producing smaller cub litters, which the team projected will continue to decline for the next three polar bear generations. With global warming and sea-ice declines, it becomes harder for polar bears to hunt their preferred preyseals. The bear, found at the southern tip of Banks Island in Canada's Northwest Territories, didn't look like a typical polar bear. "The result is you have polar bears spending more time on land and grizzly bears spending more time where polar bears might be, and so the result is that we're seeing these occasional hybrids between two species.". Mr Servheen said it was hard to know how many of the bears existed. Flight Center, NASA Earth Observatory (2019, September 24).

Cub litter size was also affected by the body condition of the mothers and by sea-ice availability. Reported first by Thred, according to researchers, rising global temperatures has forced the two species to congregate together and this frequency has now risen considerably, resulting in more interbreeding.
