This book was released on 1988 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Migratory behavior of Rocky Mountain mule deer (Odocoileus hemionus hemionus) wintering on the east side of the Sierra Nevada, Inyo and Mono counties, was studied from January 1984 to November 1987. Radio-telemetry indicated no differences between years in timing of migration from the winter range, although generally females proceeded males. Upon leaving the winter range, deer moved to spring holding areas on the east slope at higher elevations. There were no year or sex differences in leaving spring holding areas for summer ranges. Summer ranges were mainly on the western slope. Summer home ranges of males were at higher elevations, nearer water, and on steeper slopes than those of females. Fill migration was influenced by snowstorms, particularly in males. Few opportunities for habitat improvement exist on either summer or winter range. Antlerless harvests of deer during periods of population growth can dampen fluctuations in animal numbers caused by variable rainfall.

Available in PDF, EPUB and Kindle. Book excerpt: The editors utilize their 50 years of combined experience in professional engagement with the behaviour and ecology of wild felids to draw together a unique network of the world's most respected and knowledgeable experts. For the first time, this inter-disciplinary research programme is brought together within a single volume. Beginning with a complete account of all 36 felid species, there follow 8 comprehensive review chapters that span all the topics most relevant to felid conservation science, including evolution and systematics, felid form and function, genetic applications, behavioural ecology, management of species that come into conflict with people and control of international trade in felid species, conservation tools/techniques, ex situ management, and felid diseases. 19 detailed case studies then delve deeply into syntheses of the very best species investigations worldwide, written by all the leading figures in the field. These chapters portray the unique attributes of the wild felids, describe their fascinating (and conflicting) relationship with humans, and create an unparalleled platform for future research and conservation measures. A final chapter analyses the requirements of, and inter-disciplinary approaches to, practical conservation with cutting-edge examples of conservation science and action that go far beyond the cat family.

Available in PDF, EPUB and Kindle. Book excerpt: Vital rates of large herbivores normally respond to increased resource limitation by following a progressive sequence of effects on life-history characteristics from survival of young, age at first reproduction, reproduction of adults, to adult survival. Expected changes in life-history characteristics, however, should operate through changes in nutritional condition, which is the integrator of nutritional intake and demands represented primarily by the deposition and catabolism of body fat. Elucidating seasonal patterns of nutritional condition and its relative influence on individual and population performance should improve our understanding of life-history strategies and population regulation of ungulates, provide insight into the capacity of available habitat to support population growth, and allow assessment of the underlying consequences of mortality on population dynamics. We acquired longitudinal data on individual female mule deer (Odocoileus hemionus), and linked those data with environmental and population characteristics. Our goal was to provide a nutritional basis for understanding lifehistory strategies of these large mammals, and to aid in the conservation and management of large herbivores in general. We studied a migratory population of mule deer that overwintered in Round Valley on the east side of the Sierra Nevada, California, USA, and was subject to a highly variable climate and predation from a suite of large carnivores. We intensively monitored nutritional and life-history characteristics of this population during 1997-2009 as it recovered from a population crash, which occurred during 1985-1991. Deer in Round Valley migrated to high-elevation summer ranges on both sides of the crest of the Sierra Nevada (Sierra crest), where a rain shadow resulted in a mesic and more forested range on the west side compared with xeric conditions east of the Sierra crest. Average survival of neonatal mule deer to 140 days of age during 2006-2008 was 0.33 (SE1/40.091), but was lower for neonates on the west side (0.13, SE1/40.092) compared with those on the east side (0.44, SE1/40.11) of the Sierra crest. Birth mass and nutritional condition of mothers had a positive effect on survival of young; however, those effects were evident only for neonates born east of the crest where predation pressure was less intense compared with the west side. Black bear (Ursus americanus) predation was the main cause of mortality for west-side young (mortality rate1/40.63, SE1/40.97) compared with canid and felid predation for east-side young (0.29, SE1/40.076). Mean autumn recruitment of young during 1997-2008 was lower for females on the west side (0.42, SE1/40.037) than for females on the east side (0.70, SE1/40.041) of the crest, and was affected positively by March ingesta-free body fat (IFBFat) of individual females. At the level of the population, ratios of young-to-adult females (1991-2009) were highly variable and strongly related to March IFBFat of adult females during the current and preceding year. Reproduction by yearling females was sensitive to per capita availability of forage during summer (as 1-yr-old individuals), thereby influencing whether a sufficient body mass for ovulation was obtained. Litter size remained high (1.69, SE1/40.027) during the study, but was influenced positively by forage availability, negatively by summer temperature, and was greater for females that resided on the west side of the Sierra crest during summer than those on the east side. In contrast, pregnancy rates remained unchanged across years of study (0.98, SE1/40.005). Survival of prime-age (2- to 9-yr-old) females was 0.90 (SE1/40.021) in summer, 0.94 (SE1/40.012) in winter, and 0.87 (SE1/40.025) annually. Although relatively stable across years, both winter and summer survival were influenced positively by the preceding April snowpack relative to the density of the population. Mean IFBFat of adult females was 7.2% (SE1/40.077) in March 1997-2009 and 9.7% (SE1/40.23) in November 2002-2008. Nutritional condition offered a mechanistic link between factors that influence resource limitation and population performance, because condition of adult females in autumn and late winter was sensitive to the nutritional history of individual animals as related to forage growth, population density, migratory tactic, reproductive costs, and nutritional carryover. Nutritional condition of adult females in March also was the most parsimonious predictor of finite rate of population growth (l) during the forthcoming year. The relative magnitude of effect of nutritional condition on survival and reproduction was mostly in accordance with the predicted changes of vital rates in response to resource limitation for populations of large herbivores. Our results indicate that management and conservation of large herbivore populations could be improved by integrating indices of nutritional condition into current monitoring and research programs. We offer a method to estimate the proximity of a population to nutritional carrying capacity (NCC) that is based on nutritional status of the population relative to population performance (termed animal-indicated NCC). The proximity of the population to animal-indicated NCC represents the short-term capacity of the environment to support population growth. A nutritional approach to monitor and manage populations offers a direct link to the capacity of the habitat, and reduces the need to estimate population abundance or set goals according to population size. We also propose that the consequences of mortality (degree of additive or compensatory mortality) on population dynamics can be assessed by comparing the estimated nutritional capacity for survival and recruitment of young to that measured empirically, because more young are produced than what the habitat can support when nutrition is limiting. Our approach is useful for quantifying effects of predation, and provides a basis for determining the efficacy of predator control to enhance ungulate populations.

This book was released on 2023-04-27 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Black-tailed and mule deer represent one of the largest distributions of mammals in North America and are symbols of the wide-open American West. Each chapter in this book was authored by the world’s leading experts on that topic. Both editors, James R. Heffelfinger and Paul R. Krausman, are widely published in the popular and scientific press and recipients of the O. C. Wallmo Award, given every two years to a leading black-tailed and mule deer expert who has made significant contributions to the conservation of this species. In addition, Heffelfinger has chaired the Mule Deer Working Group sponsored by the Western Association of Fish and Wildlife Agencies for more than 15 years. This working group consists of the leading black-tailed and mule deer experts from each of 24 states, provinces, and territories in western North America, putting them at the forefront of all conservation and much of the research on this species. The book represents all current knowledge available on these deer, including how changing conditions such as fires, habitat alteration and loss, disease, climate change, socio-economic forces, energy development, and other aspects are influencing their distribution and abundance now and into the future. It takes a completely fresh look at all chapter topics. The revisions of distribution, taxonomy, evolution, behavior, and new and exciting work being done in deer nutrition, migration and movements, diseases, predation, and human dimensions are all assembled in this volume. This book will instantly become the foundation for the latest information and management strategies to be implemented on the ground by practitioners and to inform the public. Although this book is about deer, the topics discussed influence most terrestrial wildlife worldwide, and the basic concepts in many of the chapters are applicable to other species.

This book was released on 1988 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern cattle were having negative impacts on female mule deer prompted a study of their relationships on summer range in the Sierra Nevada. There were three phases of the study: determine the influence of cattle grazing leve on habitats; determine habitat selection patterns of radio collared does and cattle; determine the influence of cattle grazing level on doe home range and spatial use patterns. To examine these relationships, the McCormick Creek Basin was divided into three grazing units for manipulating cattle stocking level. Home ranges increased in area as grazing level increased, with deer more evenly using their home ranges. Observations indicated that does mainted greater distances from cattle than expected and temporarily avoided areas of overlap when cattle were present. With the exception of aspen stands, deer did not avoid areas grazed by cattle. Consistent with competition theory, cattle caused deer to increase browse consumption, alter their habitat use patterns to include undesirable habitats, enlarge their home range areas, and temporarily avoid cattle.--Adapted from abstract.
