Responses of Bats to Forest Fragmentation in the Mississippi River Alluvial Valley, Arkansas, USA
Intense conversion of bottomland hardwood forests to rice and soybeans in the Mississippi River Valley of Arkansas has restricted the remaining forest to isolated fragments. Habitat fragmentation has proven to be detrimental to population sustainability of several species, and is the subject of inte...
