Establishing baseline values for pathogen exposure and nutritional indices is necessary to monitor population health. However, little is known about white-tailed deer (Odocoileus virginianus) pathogen exposure and nutritional condition in the Northern Great Plains. Our objective was to assess pathogen exposure and establish nutritional indices for female white-tailed deer in Dunn and Grant counties, North Dakota and Perkins County, South Dakota. During 2014, we collected blood serum from 150 adult female white-tailed deer. Pathogens with the highest antibody prevalence included West Nile Virus (WNV; 85%), epizootic hemorrhagic disease (48%), and malignant catarrhal fever (32%). Serum values for creatine …
Reproductive Failure In Largeleaf Wild Indigo In A Restored Prairie In Southeastern Minnesota, Neal D. Mundahl
Reproductive Failure In Largeleaf Wild Indigo In A Restored Prairie In Southeastern Minnesota, Neal D. Mundahl
The Prairie Naturalist
Native prairie restorations in many regions of the United States have been hindered by various herbivores consuming plant reproductive parts or products. I conducted field studies of a population of largeleaf wild indigo (Baptisia lactea) on a restored prairie in southeastern Minnesota during the growing seasons of 2010–2012 to determine the cause(s) of repeated reproductive failure. I assessed plants for browsing damage caused by white-tailed deer (Odocoileus virginianus) during the period of flowering and with a deer exclosure experiment involving caged and non-caged plants. I compared reproductive output (numbers of seed pods, viable seeds) of caged …
Use Of Late Season Standing Corn By Female White-Tailed Deer In The Northern Great Plains During A Mild Winter, Troy W. Grovenburg, Christopher N. Jacques, Christopher C. Swanson, Robert W. Klaver, Jonathan Jenks
Use Of Late Season Standing Corn By Female White-Tailed Deer In The Northern Great Plains During A Mild Winter, Troy W. Grovenburg, Christopher N. Jacques, Christopher C. Swanson, Robert W. Klaver, Jonathan Jenks
The Prairie Naturalist
Winter habitat and resource use of white-tailed deer (Odocoileus virginianus) have been studied extensively throughout their northern range. However, limited information exists on deer use of late season standing corn. We evaluated standing corn use by female white-tailed deer on winter range in north-central South Dakota during winter 2005-2006. Results indicate that cover type selection occurred at the population (P < 0.001) and home range (P < 0.001) levels. PopUlation level analysis indicated selection for standing corn (vi> = 4.31) and Conservation Reserve Program (CRP) grasslands (vi> = 2.81). Similarly, at the home range level, deer selected for standing corn (vi> = 1.35) and CRP grasslands (vi> = 1.44). Deer disproportionately increased use of standing corn and CRP …
Using Distance Sampling To Estimate Densities Of White-Tailed Deer In South-Central Minnesota, Michelle A. Larue, Clayton K. Nielsen, Marrett D. Grund
Using Distance Sampling To Estimate Densities Of White-Tailed Deer In South-Central Minnesota, Michelle A. Larue, Clayton K. Nielsen, Marrett D. Grund
The Prairie Naturalist
Distance sampling is a method of estimating population abundance and density used by wildlife biologists for several species because of its advantages relative to other techniques. However, few wildlife biologists have used distance sampling to estimate abundance of white-tailed deer (Odocoileus virginianus). We describe a distance sampling technique used to estimate prehunt and post-hunt population densities of deer in Watonwan County, Minnesota. Estimates of white-tailed deer density were compared between distance sampling versus population modeling, and costs for distance sampling versus aerial surveys were determined. We drove 2,704 km during 24 spotlight surveys conducted from 21 October to …
