CAUSE SPECIFIC MORTALITY OF DESERT BIGHORN SHEEP LAMBS IN THE FRA CRISTOBAL MOUNTAINS, NEW MEXICO, USA
… rates include low lamb recruitment and high mortality of adults due to cougar predation. No one has previously reported cause-specific mortality rates for desert bighorn lambs. My objectives were to determine the causes, extent, and timing of lamb mortality in the Fra Cristobal Mountains, New …

Depression and Death in Diabetes; 10-year follow up of all cause and cause specific mortality in a diabetic cohort
… this relationship also results in increased mortality as compared to those with depression or diabetes alone. Objective: The purpose of this study was to examine the relationship between depression and all cause as well as cause specific mortality in patients with type 2 diabetes by extending …

Social Organization, Natal Dispersal, Survival, and Cause -Specific Mortality of Red Foxes in Agricultural and Urban Areas of East-Central Illinois
… years. Mange was the major source of urban fox mortality, followed by road kill. Road kill and coyote predation mortalities were major sources for rural foxes. Urban areas may provide refugia for red foxes in North America where reestablished coyote populations persist at high densities.

TRENDS IN LIFE EXPECTANCY AND MORTALITY: A COMPARISON OF HISPANICS AND NON-HISPANICS IN THE SOUTHWEST UNITED STATES, 1990 TO 2010
… Statistic System to study trends in rates and causes of deaths among Hispanics compared to non-Hispanics in the Southwest United States. Denominators are from the Modified Age, Race/Ethnicity, and Sex file (1990) and Bridged Race Files (2000, 2010) while numerator data are from the mortality …

Comparing Different Methods of Applying Propensity Score in Controlling Selection Bias for Studies of Prostate Cancer
… on different therapies for prostate cancer because of the limitations on generalizability of randomized controlled trials. The major challenge for population-based studies using observational data is how to control for selection bias. The objective of this study was to compare the performance …

Population Ecology of Rocky Mountain Elk in the Black Hills, South Dakota and Wyoming
… a 2-year (2012–2013) study of survival and cause–specific mortality using individually marked adult cow and neonate elk (Cervus elaphus) occupying the southwestern region of the Black Hills. We used known-fate analysis in Program MARK for survival analysis of adult cows and calves. We …

Movements, Survival, and Sightability of White-Tailed Deer in Southeastern South Dakota
… but not limited to movements, survival and cause-specific mortality. It also is helpful to examine population size and density. The primary objectives of my study were to document seasonal migration, estimate survival rates for female adult white-tailed deer, and generate a sightability …

An Evaluation of Life History Parameters of White-Tailed Deer (Odocoileus virginianus) in North Dakota
… of our study were to document movements, cause-specific mortality, survival rates, and habitat selection of white-tailed deer. We captured and radiocollared 75 (62 adult female, 13 neonates) deer in the Wing-Tuttle region of North Dakota; 58 adult deer were residents, 21 were migrators, …

Migratory Behavior and Survival of Adult Female Elk in a Partially Migratory Population
… to a greater degree than non-migratory conspecifics. Partial migration occurs when a portion of the population migrates and the other portion remains on the shared range, and is expected to be maintained by balancing fitness between migrant and resident phenotypes. Most previous research …

Pre- to post-fledging carryover effects and the post-fledging ecology of the Dickcissel (Spiza americana)
… of avian species. Therefore, understanding causes of variation in fledgling survival may be of critical importance in conserving avian biodiversity. I examined the post-fledging ecology of the Dickcissel (Spiza americana), with emphasis on pre- to post-fledging carryover effects of nestling …

Mortality: modelling, socio-economic differences and basis risk
… uncertainty surrounding the future evolution of mortality. In addition, past mortality improvements have not been shared equally across the population, resulting in a widening of socio-economic inequalities in mortality. The uncertainty and socio-economic variability of life expectancy pose a …

Evaluation of Bobcat (Lynx rufus) Survival, Harvest, and Population Size in the West-Central Region of South Dakota
… 1) estimate annual survival rates; 2) determine cause-specific mortality; 3) estimate a population size for the western prairie region of South Dakota; 4) estimate home range size of individually marked bobcats; 5) evaluate reproductive status; and 6) build a population model. We captured and …

Population Dynamics and Spatial Ecology of White-tailed Deer in the Central Appalachian Mountains of Virginia
… changes in white-tailed deer herds are survival, cause-specific mortality, home-range variation, both broad and fine-scale resource selection, and ultimately population growth trends in response to changes in both population vital rates and hunter harvest regulations. In this study, I address each …

Movement and Association of White-Tailed Deer in Southwest Minnesota
… Furthermore, knowledge of neonate survival and cause-specific mortality provides important information regarding reproduction, sex ratios, and how preseason mortality rates affect deer harvest strategies. However, biologists are usually forced to make educated guesses pertaining to these …

Northern pintail nest site selection, nest success, renesting ecology and survival in the intensively farmed prairies of southern Saskatchewan: an evaluation of the ecological trap hypothesis
… interval (April 30 – 14 July) was 0.81 ± 0.05. Cause-specific mortality rates were greater for avian predators (0.14 ± 0.04) than other sources of mortality. The pintail’s high propensity to nest in crop stubble where nest success is low coupled with lower renesting and breeding season survival …
