Study: Warmer summers worsen tick infestations for US moose

TRAVERSE CITY, Mich. (AP) — A new study indicates climate change may be worsening winter tick infestation in moose. The study is based on observation of moose at Isle Royale National Park.

Scientists with Michigan Technological University say higher summer temperatures are quickening the development of tick eggs and boosting the number that hatch.

Moose can lose much of their bristly fur rubbing against trees to get rid of ticks. Infestation also makes them anemic and less able to reproduce.
