Deciphering evolutionary histories of Southeast Asian Ungulates
Im Verlauf von Jahrmillionen gestalteten evolutionäre Kräfte die Verbreitung und genetische Variabilität von Arten, indem sie die Anpassungsfähigkeit und Überlebenswahrscheinlichkeit dieser Arten beeinflussten. Da Südostasien eine außerordentlich artenreiche Region darstellt, eignet sie sich …

Seasonal distributions and interactions of cattle and wild ungulates in Maasailand, Tanzania
… and areas of competition between cattle and wild ungulates in Maasailand, east of Tarangire Park. Subsistence pastoralism was the main form of land use and was the object of livestock development efforts. The area also was the wet season dispersal area for Tarangire ungulates and harbored a …

Greater Sage-grouse habitat and demographic response to grazing by non-native ungulates
… movements, and habitat to grazing by non-native ungulates in Northern Nevada and Southern Oregon over the course of 5 years. The study area was comprised of three large subunits, with substantially different grazing regimes. I used Bayesian Hierarchal modeling to account for uncertainty in each …

Natural and anthropogenic influences on elephants and other ungulates in the Congo forest
… models for elephants and other forest ungulates to examine temporal changes in their densities as a result of changes in human impact in the context of a civil war that took place in the region between the two surveys. Covariates related to human influences dominated the observed …

MONITORING SURVIVAL OF YOUNG IN UNGULATES: A CASE STUDY WITH ROCKY MOUNTAIN ELK
… Wildlife Biology MONITORING SURVIVAL OF YOUNG IN UNGULATES: A CASE STUDY WITH ROCKY MOUNTAIN ELK Chairperson: Daniel H. Pletscher Survival of young is an important determinant of population growth and persistence in ungulate populations. Therefore, monitoring the survival of young is an essential …

Thermal physiology of selected African ungulates with emphasis on the physical properties of the pelage
The ungulates include some of the largest land animals and, in consequence, they cannot avoid climatic stress as do small mammals. A great deal of information concerning the physiology of thermoregulation in domestic ungulates is available but relatively little is known about thermoregulation in …

Effects of Fire on the Nutritional Ecology of Selected Ungulates in the Southern Black Hills, South Dakota
<p>Research in the 1990s indicated that populations of white-tailed deer (Odocoileus virginianus) in the northern and central Black Hills had declined since the late 1970s likely due to habitat deterioration. In August 2000, the Jasper fire consumed nearly 35,000 ha of ponderosa pine (Pinus …

Indians, ungulates, and unconventional oil : the protection of culturally significant environmental features through multi-jurisdictional human rights law
The thesis considers the expansive interpretation of established human rights law from the provincial, domestic, regional and international legal spheres to protect environmental features crucial to the continued existence of indigenous cultures. Specifically the research will assess whether a …

Are animals choosing foraging patches according to spatial scaling laws or predator avoidance arguments? : a study on grazing ungulates in Hluhluwe Imfolozi
Spatial scaling laws predict that patch choke in animals in determined by body size, with smaller animals utilising smaller patches. However, this theory does not take into consideration the potential impact predator avoidance behaviour may have on patch choice. Smaller animals are more at risk …

Ecology of Mountain Lions (Puma concolor) in the North Dakota Badlands: Population Dynamics and Prey Use
… lion diets. Ungulate kill rates were 1.09 ungulates/week ± 0.13 [SE] in summer and 0.90 ungulates/week ± 0.11 in winter. Estimates of total biomass consumed were 5.8 kg/day ± 0.56 [SE] in summer and 7.2 kg/day ± 1.01 in winter. Scavenge rates were 3.7% in summer and 11.9% in winter. Prey …

The distribution and habitat preferences of wild ungulates and cattle in Lochinvar National Park, Zambia and the use of resources by people living adjacent to the park
… The distribution and habitat preferences of wild ungulates and cattle were determined from observations and counts in Lochinvar National Park and the Game Management Area (GMA) on the west em part of the park on the Kafue river floodplain of Zambia over five months. Oribi, zebra and lechwe were …

Habitat Selection and Resource Use by Bighorn Sheep Following Translocation
Recovery of North American ungulates is one of the greatest conservation success stories of the 20th century. Following widespread extirpations resulting from novel diseases, habitat fragmentation, and overharvest leading up to the 20th century, numerous conservation measures were implemented by …

Assessment of environmental and anthropogenic factors that affect movement of sedentary blue wildebeest (Connochaetes taurinus) in the Kalahari region of Botswana
Numerous species of ungulates are forced to face the effects of rising temperatures and anthropogenic influences. The most dramatic effects of these concerns have been documented in Southern Africa, where wildlife and livestock are often the main source of income. This research uses the Kalahari …

The use of faunal evidence to reconstruct site history and Hoedjiespunt 1 (HDP1), Western Cape
… palaeontological site is dominated by grazing ungulates and carnivores. This assemblage was accumulated during a period of lowered sea level, or "glacial". On the other hand, the sample from the archaeological site contains proportionally fewer ungulates and carnivores, more small animals and …

The effects of herbivory, competition, and disturbance on island meadows
… for light. Specifically, I showed that ungulates limited the establishment, growth, survival and reproduction of seedlings and transplanted native forbs and shrubs and that competition from non-native species had little effect. I also calculated forage selectivity indices and tested the …

Investigating the hidden costs of livestock guarding dogs and the diet of a sympatric predator in Namaqualand, South Africa
… dogs operating independently contained domestic ungulates, less than 5% of scats from dogs with a human attendant contained livestock. For caracals, 185 collected scats were analysed across two land uses: Namaqua National Park and surrounding farms. Eighteen mammalian prey species were identified …
