Kathleen Longshore
Dr. Kathy Longshore is a Scientist Emeritus with the Western Ecological Research Center.
Her research interests are in animal ecology with emphasis in the application of behavioral ecology to wildlife management and conservation in arid ecosystems. Behavioral indicators can provide an early warning to population declines or habitat degradation before numerical or ecosystem-level responses are evident. As such, they can be used to monitor the effectiveness of management programs. Dr. Longshore's work encompasses both basic and applied aspects of animal behavior with a specific focus on direct and indirect anthropogenic impacts on animal behavior that may in turn, may impact biodiversity.

Estimates of density, detection probability, and factors influencing detection of burrowing owls in the Mojave Desert
We estimated relative abundance and density of Western Burrowing Owls (Athene cunicularia hypugaea) at two sites in the Mojave Desert (200304). We made modifications to previously established Burrowing Owl survey techniques for use in desert shrublands and evaluated several factors that might influence the detection of owls. We tested the effectiveness of the call-broadcast technique for surveyingAuthorsD.E. Crowe, K.M. LongshoreNocturnal movements of desert bighorn sheep in the Muddy Mountains, Nevada
Adequate management of a species requires complete knowledge of its ecology, including both nocturnal and diurnal behavior. Knowledge of the movement behavior of bighorn sheep can provide insight for understanding spatial population processes as the combined result of individual behavior, physiological constraints, and fine-scale environmental influences. However, because of past difficulties in tAuthorsKathleen M. Longshore, Chris E. Lowrey, Matthew Jeffress, Daniel B. ThompsonCompensating for diminishing natural water: Predicting the impacts of water development on summer habitat of desert bighorn sheep
Artificial water sources have been used for decades to enhance and restore wildlife habitat but the benefits of their use have been subject to debate. During the past century, the number of natural springs in Joshua Tree National Park, California, USA, has declined. In response to concerns about the viability of the bighorn sheep (Ovis canadensis nelsoni) population, a number of water developmentsAuthorsK.M. Longshore, C. Lowrey, D.B. ThompsonQuantifying landscape ruggedness for animal habitat analysis: A case study using bighorn sheep in the Mojave Desert
Terrain ruggedness is often an important variable in wildlife habitat models. Most methods used to quantify ruggedness are indices derived from measures of slope and, as a result, are strongly correlated with slope. Using a Geographic Information System, we developed a vector ruggedness measure (VRM) of terrain based on a geomorphological method for measuring vector dispersion that is less correlaAuthorsJ.M. Sappington, K.M. Longshore, D.B. ThompsonDesert tortoise (Gopherus agassizii) survival at two eastern Mojave Desert sites: Death by short-term drought?
Survival of adult Desert Tortoises (Gopherus agassizii) appears related to site-specific variation in precipitation and productivity of annual plants. We studied adult tortoise survival rates at two closely situated, but physiographically different, sites in the eastern Mojave Desert over a nine-year period (spring 1992 to spring 2001). Survival rates were initially derived from population surveysAuthorsKathleen M. Longshore, Jef R. Jaeger, J.
