USGS Finds Horsehoe Crabs in Decline Print

A new study co-authored by USGS scientists has used genomics to show that a distinct decline in horseshoe crab numbers has occurred that parallels climate change associated with the end of the last Ice Age. The new research largely supported findings of recent significant declines in all areas where horseshoe crabs occur along the West Atlantic Coast from Maine to Florida and the eastern Gulf of Mexico, and it the findings indicate that horseshoe crabs numbers may continue to decline in the future because of predicted climate change.
