Genetic Evaluation Of The Current Distribution And Possible Diffrentations Between Lasiurus Borealis And Lasiurus Frantzii In Southwestern North America, Zeinab M. Haidar
Genetic Evaluation Of The Current Distribution And Possible Diffrentations Between Lasiurus Borealis And Lasiurus Frantzii In Southwestern North America, Zeinab M. Haidar
Cal Poly Humboldt theses and projects
Several recent accounts of overlap and historic misidentifications regarding two species of the genus Lasiurus, Western red bat (Lasiurus frantzii) and Eastern red bat (Lasiurus borealis), have cast doubt on our understanding of their distribution, assumed spatial allopatry, and interactions in the United States Southwest. With the use of morphometrics and genetic sequencing, utilizing tissue collected from specimens throughout California and adjoining states, we have reassessed the current distribution, best practices for field identification, and genetic differentiation between both species. Appropriate species classification by region was achieved utilizing mitochondrial DNA, targeting the cytochrome c oxidase …
Ecology Of Coyotes (Canis Latrans) In The Greater Detroit Area Of Southeastern Michigan, William B. Dodge
Ecology Of Coyotes (Canis Latrans) In The Greater Detroit Area Of Southeastern Michigan, William B. Dodge
Wayne State University Dissertations
Coyote distribution and habitat use, diet and foraging behavior and space use patterns were investigated in the greater Detroit area of southeastern Michigan. We found evidence of coyotes on 24 of 30 (80%) suburban and 7 of 11 (64%) urban plots. Overall fifty-eight percent of coyote evidence was found within edge habitats, with den sites and tracks the only types of evidence found strictly in interior habitats. Land cover around evidence points included more wooded land cover than expected in suburban areas, suggesting the importance of tree cover for coyote occupancy, and more open space and wooded land cover than …
The Effects Of Soil Ph On The Molting Success Of Blacklegged Ticks (Ixodes Scapularis): A Laboratory Experiment, Daniel Rice
The Effects Of Soil Ph On The Molting Success Of Blacklegged Ticks (Ixodes Scapularis): A Laboratory Experiment, Daniel Rice
Honors Theses
Ixodes scapularis, or the black-legged tick, is the major vector of Lyme disease in the U.S. I. scapularis has expanded its range in recent decades, making the study of factors affecting its distribution a high priority. Studying the effects of various conditions in the soil could help in predicting range expansions, because ticks spend the majority of their lives in contact with the soil. We investigated the effects of soil pH on the molting success of engorged I. scapularis nymphs collected from Eastern Chipmunks (Tamias striatus). The experiment was conducted in a laboratory to control for covariates such as temperature …
