Mechanisms Maintaining Additive Genetic Variance in Fitness in Red Squirrels
… models’ to examine a long-term population of red squirrels to determine 1) if either sexual antagonism or temporal fluctuations in selection were maintaining direct Va in fitness or 2) if maternal genetic effects were a source of indirect Va in fitness. While there were environmental …

Barrier Effects Of Roads And Traffic On Animal Occurrence, Space Use, And Movements
… edge, and gap avoidance. We used an endangered forest obligate, the Mount Graham red squirrel (Tamiasciurus hudsonicus grahamensis), as our study organism to assess effects of traffic noise on animal occurrence and demonstrated that traffic noise had spatially extensive and negative effects …

A Study of factors influencing a non-cyclic, island population of snowshoe hares
… that on the adjacent mainland. Hare densities, predation rates, reproduction and juvenile survival were all monitored on both Jacquot Island and mainland study areas. Habitat on the study sites was also examined for cover and browse availability. Jacquot Island juveniles had survival rates 3-15 …

Linking fitness and the microbiota: exploring variation in microbial composition in the North American red squirrel (Tamiasciurus hudsonicus).
… In this thesis, the promiscuous North American red squirrel, Tamiasciurus hudsonicus, was used to investigate if oral, gut, and genital microbiota differed with correlates of host fitness, sex, or capture period. These objectives were met using various sequencing techniques, including 454-Roche …

Ecological Process and the Blister Rust Epidemic: Cone Production, Cone Predation, and Seed Dispersal in Whitebark Pine (Pinus albicaulis)
… habitat use of whitebark pine forests by red squirrels (Tamiasciurus hudsonicus). Squirrel residency and impact of cone predation increased with decreasing whitebark pine abundance. The third manuscript focuses on the tree-level ecological process, predispersal cone survival, as a function …

The 2006 Warm Fire: effects on habitat and prey species of the northern goshawk
Reductions in the frequency of fire in Southwestern ponderosa pine and mixed-conifer forests since initiation of forest management early in 20th century changed the composition and structure of the forest habitats of the northern goshawks (Accipiter gentilis), a food-limited species of conservation …
