A new publication has recently been added to the Biological Resources section of the Northern Prairie Wildlife Research Center site. This resource, by Pamela J. Pietz and Gary L. Krapu, was originally published in 1994 in the Wildlife Society Bulletin (Vol 22: 26-33). Pietz and Krapu showed that installing "ground-level exits in predator exclosures with mesh fences" improved predator exclusion while reducing delays in brood leading (from nests to wetlands). The report may be browsed on-site or downloaded as a complete file (.zip).
