Presentations at Professional Meetings
I regularly present and co-author papers at regional and national meetings. For example, in 2006-07, I co-authored 9 papers with students at three CA meetings: 1) Western Section of The Wildlife Society, Monterey; 2) Pacific Seabird Group, Asilomar; and 3) Society of Wetland Scientists, Sacramento.
