This book was released on 2015 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to determine white-tailed deer (Odocoileus virginianus) browsing preferences for tree and shrub species in riparian zones of Northeastern Ohio. A total of five sites were selected along the Grand River and Pymatuning Creek in Trumbull County, and along the Cuyahoga River in Geauga County. In autumn of 2012, three to five 12 x 20 m quadrats were established in a stratified random fashion at each site, and the canopy species composition was surveyed for each quadrat. For individual tree species that had foliage accessible to white-tailed, deer the following data were recorded quantitatively and/or categorically: total available browse, type of available browse, and severity of browsing. The shrub and sapling layer was also surveyed within two randomly placed 4x4 m nested plots per 12x20 m overstory quadrat. The Jacob's Electivity Index was used to assess browsing preferences for tree and shrub species. As determined by the Jacob's Electivity Index various tree and shrub species: 1) were consistently avoided at all quadrats when present (bitternut and shagbark hickories, swamp and black ashes, black cherry, American basswood, and American elm), 2) were consistently selected in all quadrats where present (American hornbeam and black willow), or 3) varied widely in their selection by deer (silver and sugar maples). Quadrats containing sugar and, especially, silver maple with epicormic sprouts had greatest total browsing impact. Results suggest that white-tailed deer herbivory may actually reflect a Marginal Value Theorem model dictated by patches abundant in such sprouts. Further research is needed to determine potential effects of white-tailed deer in hindering the regeneration of such flood and/or beaver damaged vegetation in Northeastern Ohio riparian zones.

This book was released on 2020 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Human activity affects white-tailed deer (Odocoileus virginianus) movement and habitat selection during all times of the year, but knowledge is limited regarding how human risk affects white-tailed deer during the summer and winter. During spring and summer, variation in patch selection varied. Natural vegetation was selected for early in the year, with anthropogenic forages being important for deer use during the summer. During the winter, deer responded to different levels of risk. As hunter risk increased on the landscape, deer altered selection of the landscape. Deer avoided areas that were heavily used by hunters, using areas containing less hunter risk. Use of land cover classifications varied temporally, with cover selected for during the day and forage selected for at night. I have demonstrated that deer respond to human activity on the landscape, by selecting for anthropogenic foraging sources during the spring and summer and avoiding patches that contain risk.

Available in PDF, EPUB and Kindle. Book excerpt: Easily the most common of America’s large wildlife species, white-tailed deer are often referred to as "overabundant." But when does a species cross the threshold from common to overpopulated? This question has been the focus of debate in recent years among hunters, animal rights activists, and biologists. William McShea and his colleagues explore every aspect of the issue in The Science of Overabundance. Are there really too many deer? Do efforts to control deer populations really work? What broader lessons can we learn from efforts to understand deer population dynamics? Through twenty-three chapters, the editors and contributors dismiss widely held lore and provide solid information on this perplexing problem.

Laux and published by . This book was released on 2013 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Browsing by white-tailed deer has alters plant species diversity of the forest understory across much of North America. A reduced understory may lead to the simplification of the forest-floor microhabitat, causing broad scale shifts in the community composition and abundance of litter-dwelling arthropods and small mammals. The objectives of this study were to 1) document changes in the forest-floor microhabitat as a result of over-browsing by deer and 2) determine if differential browsing pressures indirectly affect faunal biodiversity (litter-dwelling arthropods and small mammals) of forest ecosystems. I predicted that browsing within the understory will reduce structural complexity of the forest-floor microhabitat, and its dependent community. A combination of comparative (high vs. low deer impact) and exclosure studies were used to document the effects of herbivory on forest ecosystems. Fewer seedlings and less herbaceous and canopy cover occurred in areas outside exclosures and in areas heavily impacted by deer in contrast to those impacted less, and as percent herbaceous cover correlated strongly with leaf litter biomass and depth, browsing reduces structural complexity of the forest-floor microhabitat. More mesofauna, Coleoptera and Araneae, were present inside than outside deer exclosures. Non-native species (i.e., centipedes, gastropods, isopods and millipedes) were more abundant in areas of high deer impact compared to areas of lower impact. No differences in small mammal abundance were detected in response to the indirect effects of browsing; however, areas of low impact were more speciose and supported significantly more insectivorous small mammals (Soricidae). Soricids require moist habitats with adequate cover and ample invertebrate prey. Capture rates of the Masked Shrew, Sorex cinereus, were positively correlated with litter depth and invertebrate abundance of the preceding year. These findings suggest that even where total soricid and arthropod abundance did not vary in response to differential levels of deer impacts, simplification of the forest-floor microhabitat can reduce diversity and species composition of litter-dwelling animals. Deer may also facilitate the invasion of non-native species and alter trophic cascades within the forest-floor ecosystem.
