This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book excerpt: Abstract : Winter in the northern Great Lakes presents a suite of challenging conditions for animals, in terms of limited food availability and increased energetic cost of locomotion and thermoregulation. Variable winter severity is liable to cause interannual fluctuations in habitat viability and use by animals, in addition to modulating physiological responses in animals to conserve energy. For example, white-tailed deer (Odocoileus virginianus) congregate at high densities under eastern hemlock (Tsuga canadensis) or northern white-cedar (Thuja occidentalis) stands, which provide forage, thermal cover, reduced snow depth, and enhanced vigilance. However, a suite of climatic, edaphic, and management changes, in addition to novel deer densities, have compromised regeneration of eastern hemlock in recent years, while facilitating the propagation of hardwoods. For this research, I monitored 39 randomly selected eastern hemlock stands across the western Upper Peninsula. I selected a subset of 15 of these stands to survey for forest community composition and assess changes between 2006 and 2015, and found evidence of a transition to hardwoods such as maple (Acer rubrum and A. saccharum). This change in forest composition will have significant implications for migratory white-tailed deer, particularly when coupled with more extreme winter conditions predicted to occur with climate change. I monitored local deer use in all 39 stands from winter 2014-15 to 2017-2018, building on a dataset extending back to winter 2005-2006, by counting fecal pellet groups in each stand, and found evidence of reduced use following recent severe winters, as well as a spatial shift in intensity of use. I assessed diet composition by collecting fecal samples during spring pellet surveys, and found evidence of spatial variability in the diet, likely due to spatiotemporal variation in winter severity. To further understand the physiological implications of winter severity and winter diet, I assessed physiological stress response (via non-invasive fecal glucocorticoids) and found evidence of endocrine down-regulation in animals with a poor diet and in extreme conditions. My findings underscore the importance of maintaining a mesic conifer component in northern forests to provide winter habitat for regional migratory deer populations.

This book was released on 2014 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Many factors influence woody seedling regeneration in north temperate forest ecosystems. One important factor is snow depth, which may in turn interact with herbivory by white-tailed deer (Odocoileus virginianus). In this study we measured variation in snow depth at a northern Wisconsin hardwood forest over two winter seasons, 2012-2013 and 2013-2014. Snow measurements were taken approximately bi- weekly at 60 locations in the 25 hectare Wabikon Forest Dynamics Plot (WFDP) near Crandon, WI, USA. White-tailed deer herbivory was assessed at 275 2x1 m subplots within the WFDP during summer 2013. Our objectives were to identify biotic and abiotic variables that affected snow depth and to associate snow depth with seedling herbivory and mortality. Results showed that biotic variables had significantly greater impact on snow depth than abiotic variables such as slope, elevation, and aspect. Seedling herbivory and mortality during these two years were unrelated to local variations in snow depth. Deer were virtually absent from most of the forest plot during winter months. Both field seasons experienced above average snow levels, so this finding might not apply during all years. Nevertheless, our results shed important light on the dynamics of snow accumulation and melting in northern hardwood forests and suggest that snow inhibits deer browsing during winter. The effects of snow cover on deer browsing are especially important in light of predicted climate change, which may lead to reduced snow cover and therefore increased herbivory of seedlings.

This book was released on 1990 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A study to evaluate white-tailed deer winter range use in relation to forest stand and weather conditions was conducted during three winters from 1983-1986. Data were collected from 16.1 km (10 mi.) of ground transects and 20 radio-collared deer located on winter range in the study area. One hundred thirty seven telemetry locations were evaluated with a GEOSCAN cartographic program. The program scanned 40 ha (100 ac.) around each location to generate a frequency distribution of cover types from a digitized vegetation map. A winter severity index was used to classify transect and telemetry observations of deer use into mild, moderate and severe winter condition categories. Under mild winter conditions, white-tailed deer used 13 cover types in proportion to their availability on the winter range. Observed proportion of cover type use by deer under moderate and severe winter conditions differed from that expected. Deer utilized openings, lightly stocked plantations, and riparian pole-sized timber significantly less than availability and preferred upland pole and riparian sawtimber-sized stands. Multiple regression analysis of snow depth, percent canopy closure and aspect vs. deer use was significant, especially when snow depth exceeded 40 cm (13 in.). Discriminant function analysis was not particularly effective in identifying habitat variables to predict deer occurrence under mild and moderate conditions. The discriminating variables for severe winter conditions were one tree basal area variable, one diversity related variable, one aspect variable, and one stand type variable. Reductions in deer use one year following timber harvest ranged from 52-85% and were related to reductions in canopy closure. Overall rankings of cover type use derived from transects did not differ significantly from rankings obtained by telemetry. However, large differences in individual cover type rankings between techniques were observed in conifer plantations and upland sawtimber cover types. Rankings of cover type use derived from both techniques were correlated. The relationship between forest structural components on winter ranges and the silvicultura1 practices which affect them is discussed. Guidelines for winter range si1vicultcra1 treatments are proposed. Management implications of the guidelines are discussed. The distribution of winter range structural types in the study area was within recommended guidelines"--Leaf ii.
