Richard Bovbjerg And The Iowa Lakeside Laboratory, Michael J. Lannoo Jan 1990

Richard Bovbjerg And The Iowa Lakeside Laboratory, Michael J. Lannoo

Journal of the Iowa Academy of Science: JIAS

In the spring of 1977, in Ames, a struggling biology major who had earlier shown some promise was ordered by his advisor: "Go to Lakeside Lab and take Dick Bovbjerg's Aquatic Ecology course." I did and it worked. I've parlayed that early potential into a career. And like so many others I return to Lakeside, the first time to take another course, then to do my Master's research. More recently I come back to teach the Field Vertebrate Zoology course. Likewise, Dick has shifted from mentor to colleague, and we've co-authored a paper (Lannoo and Bovbjerg, 1985). Now, I am …


Changes In A Prairie Bird Population From 1940 To 1989, Neil P. Bernstein, Kristine K. Baker, Sherry R. Wilmot Jan 1990

Changes In A Prairie Bird Population From 1940 To 1989, Neil P. Bernstein, Kristine K. Baker, Sherry R. Wilmot

Journal of the Iowa Academy of Science: JIAS

We repeated a bird census of a prairie/field community that was done by Kendeigh (1941) in 1940. Changes in the bird populations were compared with changes in vegetation, agricultural land use for the county, and trends in urbanization. Grassland birds did decline in abundance due to causes similar to those cited in other studies. The increase in forest and edge nesting species was more unusual to this study, and probably correlated with the woody succession that had occurred.
