A Multispecies Perspective Into Dietary Genetic Adaptations And Ancient Migration In The Peruvian Andes, Kelsey Jorgensen
A Multispecies Perspective Into Dietary Genetic Adaptations And Ancient Migration In The Peruvian Andes, Kelsey Jorgensen
Wayne State University Dissertations
Successful adaptation to the high-elevation Andes would have required both cultural and biological adaptations by early human populations. These past adaptations continue to shape the evolutionary outcomes of both humans and non-human species today. A multispecies perspective was used to examine how humans and non-human creatures, specifically insects, were shaped by past human adaptations. This dissertation asked two primary questions: 1) Given the importance and evolutionary history of potato consumption in the Peruvian Andes, is a genetic adaptation to better digest potato starch detectable in present-day Peruvians? and 2) Using the Andean Potato Weevil (APW) phylogeny as a proxy, what …
The Digestive Composition And Physiology Of Water Mites, Adrian Amelio Vasquez
The Digestive Composition And Physiology Of Water Mites, Adrian Amelio Vasquez
Wayne State University Dissertations
Water mites are a diverse group of arachnids that inhabit aquatic habitats and have been studied in the past for their biodiversity, unique lifecycle, bioindicator species use and for their impact as parasites on insects of human pathological significance such as the mosquito. Water mites are critical in their environment as possible apex predators however, their life cycle and morphological complexity has made taxonomy and description of water mites difficult. Although water mite species richness is estimated at over 6000 species described to date, descriptions of extant North American water mite species are estimated to be only 50% of the …
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 …
