Spouting humpback whales are part of the picturesque landscape of Frederick Sound, Alaska. The majesty of these and other marine mammals has captured the attention of conservationists who devote time and money to saving them from possible extinction. In "Measuring Success in Conservation," Leah Gerber, Douglas DeMaster and Simona Perry Roberts demonstrate the need to assess objectively the status of these recovery efforts. The authors argue that conservationists may be working to recover whale populations that are no longer endangered, at the expense of other animals, plants and microorganisms that actually need the help.
