Question 1

Scientists studying mammals frequently analyze scat.Why?

Accepted Answer

Scat can reveal several things.Traces of prey items can often be identified,so scat can be used to show individual preferences in prey items,seasonal changes in prey items,and to estimate overall impact of predation on prey species.Scat can also provide DNA,allowing researchers to develop genetic profiles of the owls in an area.
