Rapid endangered species assessment : a novel approach to improve extinction risk assessments in poorly known species

Creator:: Bianchi, Carlos A.
Abstract:: The number of endangered species is rapidly increasing while paucity of adequate information and resources delays establishment of conservation actions. The IUCN’s listing system is insufficient to determine conservation priorities and many species lack information even to be evaluated (i.e., “data deficient”). Here I proposed and tested the Rapid Endangered...

Impacts of Stocking Density on Development and Puberty Attainment of Replacement Beef Heifers

Creator:: Schubach, Kelsey M.
Abstract:: The following experiment presented herein compared growth, physical activity, stress-related responses, and puberty attainment in heifers reared on high- (HIDENS) or low-stocking densities (LOWDENS). Sixty Angus x Hereford heifers were ranked by age and BW (210 ± 2 d and 220 ± 2 kg, respectively) on d 0, and assigned...

Population dynamics of Microtus canicaudus

Creator:: Gilston, Richard Robert
Abstract:: Four experimental groups were designed to examine the effects of a "greens" dietary supplement (wheat clippings), as well as individual versus group-housing, on the adrenal and reproductive physiology of Microtus canicaudus. Organ culture of adrenal glands, thin-layer chromatography, and fluorescence analysis of steroid-containing medium were used to quantitatively assess adrenal...

An analysis of a small mammal population census

Creator:: Schamberger, Melvin
Abstract:: During the spring of 1963 and 1964 an investigation of a small mammal community was made in McDonald Forest, near Corvallis, Oregon. The revised North American Census of Small Mammals procedure was used, and from this census the species composition of the community was determined. The relationships of several genera...

Comparison of two direct observation techniques for enumerating Columbian blacktailed deer in western Oregon

Conditioning of unobserved period-specific abundances to improve estimation of dynamic populations

Creator:: Dail, David
Abstract:: Obtaining accurate estimates of animal abundance is made difficult by the fact that most animal species are detected imperfectly. Early attempts at building likelihood models that account for unknown detection probability impose a simplifying assumption unrealistic for many populations, however: no births, deaths, migration or emigration can occur in the...
