Differential effects of coyotes and red foxes on duck nest success
Low recruitment rates prevail among ducks in the Prairie Pothole Region of North America, primarily because of high nest depredation rates. The red fox (Vulpes vulpes) is a major predator of duckExpand

Distribution and abundance of predators that affect duck production: Prairie Pothole Region
Abstract : During 1983-88, the relative abundance of 18 species and species-groups of mammalian and avian predators affecting duck production in the prairie pothole region was determined in 33 widelyExpand

ASSESSING SMALL MAMMAL ABUNDANCE WITH TRACK-TUBE INDICES AND MARK–RECAPTURE POPULATION ESTIMATES
Abstract We compared track-tube sampling with mark–recapture livetrapping and evaluated a track-tube index, defined as the number of track tubes with identifiable small mammal tracks during a 4-nightExpand

Relationships of habitat patch size to predator community and survival of duck nests
We studied duck nest success and predator community composition in relation to size of discrete patches of nesting cover in the Prairie Pothole Region (PPR) of the United States in 1993-95 We focusedExpand

Seasonal Food Habits of Swift Fox (Vulpes velox) in Cropland and Rangeland Landscapes in Western Kansas
Abstract Food habits of swift foxes (Vulpes velox) occupying two distinct landscapes (dominated by cropland versus rangeland) in western Kansas were determined by analysis of scats collected in 1993Expand

Impact of West Nile virus and other mortality factors on American white pelicans at breeding colonies in the northern plains of North America
American white pelicans (Pelecanus erythrorhynchos) are colonial-nesting birds and their breeding sites are concentrated in a few small areas, making this species especially vulner- able to factorsExpand

Predator selection of prairie landscape features and its relation to duck nest success
Mammalian predation is a major cause of mortality for breeding waterfowl in the U.S. Northern Great Plains, and yet we know little about the selection of prairie habitats by predators or how thisExpand

Interpreting Evidence of Depredation of Duck Nests in the Prairie Pothole Region
Abstract : We examined patterns of depredation of duck nests by 9 species and 2 congeneric species-groups of predators in the Prairie Pothole Region: coyote (Canis latrans), red fox (Vulpes vulpes),Expand
