When looking for a place to set up a capture location, biologists look for existing bear sign such as scratches on trees and bear scat. Sometimes traps are set in areas that have no obvious bear sign to determine if indeed bears are present.

The pallid sturgeon is an endangered riverine sturgeon with historical distribution restricted to parts of the Yellowstone, Missouri, Mississippi, and Atchafalaya Rivers. Although rare, pallid sturgeon in the lower Mississippi River appear to be naturally recruiting, and information about habitat use is important to conserve this species.
