We can't help the animals unless we understand their needs ("Wildlife Biology Goes High-Tech," HCN, 12/10/12). In a world of ever-increasing human encroachment on the last pristine habitats, denying people their "God-given right" to property ownership requires justification, and that is why studies such as those cited in Robbins' story are invaluable. I have marked fish, frogs and turtles for telemetry, mark-and-recapture and other studies in the San Francisco Bay Area, and can attest that biologists have zero interest in a tracking technology that is cumbersome, painful or otherwise harmful to the subject as it results in a higher risk of predation and a loss of data. We are studying them because we care about them, and our jobs don't need to be made harder by people who fret that we are "hurting them."
