Persistent genetic connectivity in caribou may buffer against inbreeding effects.

Abstract excerpt

The Mulchatna Caribou Herd (MCH) in southwest Alaska has undergone significant demographic fluctuations, with a 94% decline over the past three decades, reducing the population from an estimated 200,000 to 13,000 individuals. This decline and concurrent range contraction, coupled with radio-telemetry and global positioning system (GPS)-collar studies, revealed indications of herd substructure. Females showed...
