That they're Public Enemy No. 1?
According to a recent Nature journal essay, non-natives are so vilified today that a “pervasive bias” exists against non-native species, a bias embraced by “the public, conservationists, and managers and policy-makers, as well by as many scientists, throughout the world.”
The native-vs.-non-native species distinction appears to be the “guiding principle” in today’s conservation and restoration management, say 19 ecologists in their essay, “Don’t Judge Species on Their Origins.”
Mark Davis, a biology professor at Macalester College, St. Paul, Minn., is the lead author. The other co-authors include Scott Carroll of UC Davis.
Carroll, an ecologist in professor Sharon Lawler’s lab, and the founding director of the Davis-based Institute for Contemporary Evolution, contributed his work on conciliation biology to the thought-provoking essay. He holds a doctorate in biology from the University of Utah.
“Global change alters conditions for all species, and from a practical perspective, origin can be only one of many criteria we consider,” Carroll told us. “Appraising non-native organisms more openly invites us to more seriously contemplate our aims when managing novel communities of mixed origin.”
Carroll is often out chasing soapberry bugs (a key research interest), writing research papers and delivering presentations. He considers soapberry bugs "wondrous examples of evolution happening right now--as we change the world, these beautiful insects are quickly adapting, and in the process directly revealing how evolution works."
You can't miss his presence. At 6 foot-10 inches, he towers over his colleagues.
And the soapberry bugs!
