CONSERVATION:
Droppings Give the Lowdown On Stress in the Spotted Owl
David A. Malakoff
By scooping up feces from the endangered spotted owl and measuring hormone levels there, a team of researchers has shown that logging and road building can measurably increase the animal's stress. The finding--which is stirring controversy--has raised new doubts about the adequacy of government efforts to protect the owl. It also demonstrates a potentially valuable new technique for monitoring stress in beleaguered wildlife.
