The Above-Ground Movement And Dispersal Of The Plains Pocket Gopher (Geomys Bursarius), Craig Panich Oct 2006

The Above-Ground Movement And Dispersal Of The Plains Pocket Gopher (Geomys Bursarius), Craig Panich

11th Triennial National Wildlife and Fisheries Extension Specialists Conference (2006)

The Plains pocket gopher has the largest range of its genus, and it is the gopher that inhabits much of Wisconsin. Gophers are fossorial herbivores that have a dramatic impact on natural and agricultural ecosystems. Throughout the summer of 2005, I completed a population analysis of the plains pocket gopher in a variety of habitats in Buffalo and Trempealeau Counties, Wisconsin, that provided valuable insight into the complex population dynamics of the gopher and served as a foundation to this project. Pocket gophers are known to be strictly subterranean; however, it is not uncommon to find their remains inside the …


Effects Of Predator Removal On Upland Nesting Ducks In North Dakota Grassland Fragments, Kristen D. Chodachek, Michael J. Chamberlain Mar 2006

Effects Of Predator Removal On Upland Nesting Ducks In North Dakota Grassland Fragments, Kristen D. Chodachek, Michael J. Chamberlain

The Prairie Naturalist

Low nest success rates in the Prairie Pothole Region are attributed mainly to changes in the predator community coupled with reductions in availability of suitable nesting cover. We evaluated effects of removal of mammalian predators on pair density and nest success of ducks nesting on 259 ha sites in northeastern North Dakota during 2001 and 2002. We monitored pair density and duck nests on 10 sites with removal and 10 sites without removal. Overall nest success for both years was greater on trapped (53.4%) than nontrapped sites (28.7%). Pair densities were not affected by predator removal, but did increase across …
