Plumage development and growth of young whooping cranes

Creator:: Stephenson, James Dale
Abstract:: Plumage development and growth were studied in young whooping cranes (Grus americana) from hatching until 450 days of age. The downy stage of the young cranes lasted about six weeks; the development of the juvenal plumage took until 100 days of age, and the molt to the adult or all...

Wavelet analysis : linking multi-scalar pattern detection to ecological monitoring

Creator:: Anthony, Jill Ada Marie
Abstract:: Wavelet analysis is an analytical and modeling tool for optimizing sampling efficiency and accuracy, particularly in the context of designing long-term, large-scale monitoring plans. As a pattern analysis method that accommodates and preserves non-stationarity, wavelet analysis provides novel visualization and analytical capabilities for increased insight into interactions between multi-scalar heterogeneous...

Density, sex ratio, and space use in the gray-tailed vole, Microtus canicaudus

Creator:: Bond, Monica L.
Abstract:: Female and male mammals have different behavioral strategies for maximizing their reproductive success. Pregnancy and lactation obligate female mammals to provide greater parental investment than males; thus, females compete with each other for food and space to rear their offspring, while male mammals compete with each other for female mates....

Influence of movement corridors on enclosed populations of the gray-tailed vole : do immigrants affect reproduction and dispersal of residents in a patchy environment?

Creator:: Davis-Born, Renee
Abstract:: I monitored demography, movement, and reproductive behavior of gray-tailed voles, Microtus canicaudus, in experimental habitat patches with and without corridors. I tested the hypotheses that reproductive rate, juvenile recruitment, and population size and growth rate would be affected negatively by immigrants that were introduced to resident groups (+ male and...

Effects of female kin groups on reproduction and demography in the gray-tailed vole (Microtus canicaudus)

Creator:: Dalton, Christine L.
Abstract:: The 3-5 year cyclical fluctuations in populations of many vole and lemming species have perplexed ecologists for many years. Numerous hypotheses have been proposed to explain microtine rodent cycles, including various aspects of social behavior. Microtine rodents commonly form kin groups composed of related females. Charnov and Finerty (1980) proposed...

Exposure to strangers does not cause pregnancy distribution or infanticide in the gray-tailed vole

Creator:: De la Maza, Helen M.
Abstract:: Numerous laboratory studies with at least 12 species of rodents have reported that exposure of females to strange males results in pregnancy disruption or infanticide. The proximate causes and ultimate benefits of these behaviors have been proposed from an evolutionary perspective. To determine if exposure to strange males or females...

Individual and demographic responses of the gray-tailed Vole (Microtus canicaudus) to an endocrine disruptor

Creator:: Caslin, Tracie M.
Abstract:: In an experimental field study, populations of gray-tailed voles (Microtus canicaudus) were exposed to a commercial formulation of vinclozolin, a fungicide effective for disease control on ornamental plants, turf grasses, and fruits and vegetables. Vinclozolin has been shown in laboratory experiments to behave as an androgen antagonist, impairing the reproductive...

Improving ecological risk assessment of pesticides for nontarget terrestrial vertebrates

Creator:: Wang, Guiming
Abstract:: The Quotient Method (QM) is used by the United States Environmental Protection Agency (USEPA) in ecological risk assessments of pesticides for nontarget organisms. The QM requires several assumptions regarding exposure and hazards of pesticides to wildlife; several of these assumptions have not been tested. During 1997-99, I conducted three experiments...

Ecology of mallard ducklings on Lower Klamath National Wildlife Refuge, California

Creator:: Mauser, David M.
Abstract:: The ecology of female mallards (Anas platyrhynchos) and their broods was studied during 1988-90 on Lower Klamath National Wildlife Refuge, California. Survival of 127 radio-marked ducklings from 64 broods was 0.18 to 10 days of life, and 0.37 and 0.34 to fledging for 1988, 1989, and 1990, respectively. For the...
