Effects of Urbanization on Survival Rates, Anti-Predator Behavior, and Movements of Woodchucks (Marmota Monax)
… and perceived risk from predators. I examined survival, cause-specific mortality, anti-predator behavior, and movements of adult woodchucks (Marmota monax) across an urbanization gradient within an agricultural landscape in central Illinois from 2007 to 2009. As predicted, survival rates were …

Wood Duck Brood Movements, Habitat Use, and Survival Rates on Two Prairie Rivers in South Dakota
… Wood duck brood movements, habitat use, and survival were studied by radio-marking hens nesting in boxes on the Big Sioux River, 1992-1994, and Maple River, 1993-1994, in South Dakota. The Big Sioux River is a lower perennial stream bordered by a narrow wooded corridor and a fairly wide …

Effects of Calfhood Respiratory and Digestive Disease on Calfhood Morbidity and First Lactation Production and Survival Rates
… to determine the effects of calfhood disease on survival and performance. Operator-treated respiratory disease occurrences within the first year of life and digestive disease occurrences within the first 45 d of life were analyzed to determine their effects on calfhood morbidity, age at first …

Is the Probability of Survival for A Liver Transplant Dependent on the Patient's Choice of Hospital?
… whether the differences in liver transplant survival rates for hospitals are a result of differences in patients and/or differences in hospital-specific criteria. The findings in this thesis show that most of the differences in hospital survival rates are due to patient characteristics, and …

Chirurgie der extrahepatischen Gallenwegskarzinome
… a very bad prognosis. Even though resection rates and perioperative mortality were improved, the survival rates remain unfavourably. This study investigated retrospectively the survival and success of surgical therapy of 87 patients with carcinomas of the extrahepatic bile duct and …

Bayesian hierarchical models for estimating nest survival
… OF MISSOURI-COLUMBIA AT AUTHOR'S REQUEST.] Nest survival rate is a critical value in avian study to evaluate the landbirds populations. The widely used likelihood-based logistic regression model was evaluated in the first part of the dissertation. In this part, we investigated the importance of …

Experiments to culture juvenile freshwater mussels in small tanks, floating containers and sediment beds
… with indoor sediment beds produced modest growth rates and variable survival rates for up to 4 months. Shell lengths of juveniles increased from 0.38 - 0.41 mm to 0.93 - 3.22 mm, 1.45 - 7.05 times original size; survival rates ranged from 1.27 % to 51.0 %. Experiments with indoor floating …

Reproductive Ecology of Greater Sandhill Cranes in Nevada
We evaluated factors influencing survival of nests and chicks (i.e., colts) of greater sandhill cranes (Grus canadensis tabida) in northeastern Nevada, USA, during 2009-2010. We monitored 161 nests and 101 colts and used a maximum-likelihood based approach to test multiple competing hypotheses and …
