Available in PDF, EPUB and Kindle. Book excerpt: I investigated the dynamics of sympatric elk and mule deer populations across central and southern Idaho to: 1) estimate the effects of density dependence, interspecific interactions, forage, weather, and predation and 2) develop a predictive, stochastic simulation model that integrates both species with estimated coefficients for each factor. I used estimates of annual abundance from 1990-2003, when mule deer were in decline, elk populations fluctuated, and wolf abundance steadily increased. I tested theories of density-dependent habitat selection, evaluated the relative importance of factors on population growth of each species, and used the simulation model to predict responses to simulated changes in factors.

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.

Book Synopsis Implications of Cougar Prey Selection and Demography on Population Dynamics of Elk in Northeast Oregon by : Darren A. Clark
Download or read book Implications of Cougar Prey Selection and Demography on Population Dynamics of Elk in Northeast Oregon written by Darren A. Clark and published by . This book was released on 2014 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mule deer (Odocoileus hemionus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni; hereafter elk) populations in northeast Oregon have declined in the past 10 to 20 years. Concurrent with these declines, cougar (Puma concolor) populations have apparently increased, leading to speculation that predation by cougars may be responsible for declining ungulate populations. However, empirical data on cougar diets, kill rates, and prey selection are lacking to support this speculation. Furthermore, the common assumption that cougar populations have increased in northeast Oregon may not be well founded because cougar populations in other areas within the Pacific Northwest region have declined in recent years. My primary research objectives were to (1) estimate kill rates and prey selection by cougars in northeast Oregon, (2) document causes of mortality and estimate survival rates for cougars, (3) estimate population growth rates of cougars in northeast Oregon and simulate the effects of hypothetical lethal control efforts on the cougar population, and (4) investigate the relative influence of top-down, bottom-up, and climatic factors for limiting population growth rates of elk in northeast Oregon. Results from my research will help guide cougar and elk management in northeast Oregon and provide a framework for assessing relative effects of top-down, bottom-up, and abiotic factors on population growth rates of ungulates in this and other areas. I implemented a 3-year study in northeast Oregon to investigate diets, kill rates, and prey selection of cougars in a multiple-prey system to better understand mechanisms by which cougars may influence ungulate populations. During my research, 25 adult cougars were captured and fitted with Global Positioning System (GPS) collars to identify kill sites. I monitored predation sequences of these cougars for 7,642 days and located the remains of 1,213 prey items killed by cougars. Cougars killed ungulates at an average rate of 1.03 per week (95% CI = 0.92 - 1.14); however, ungulate kill rates were variable and influenced by the season and demographic classification of cougars. Cougars killed ungulates 1.55 (95% CI = 1.47 - 1.66) times more frequently during summer (May-Oct) than during winter (Nov-Apr), but killed similar amounts of ungulate biomass (8.05 kg/day; 95% CI = 6.74 - 9.35) throughout the year. Cougars killed ungulates more frequently in summer because juvenile ungulates comprised most of the diet and were smaller on average than ungulate prey killed in winter. Female cougars with kittens killed more frequently (kills/day) than males or solitary females. After accounting for the additional biomass of kittens in cougar family groups, male cougars killed on average more biomass of ungulate prey per day than did females (R = 0.41, P
