The Effects Of Elevation On Foraging Behavior Of Bats In Southern Appalachia, Victoria Long
The Effects Of Elevation On Foraging Behavior Of Bats In Southern Appalachia, Victoria Long
Electronic Theses and Dissertations
There are limited studies on bat activity in higher elevations in the Appalachian region. Levels of bat activity were compared in south central Appalachia at low (< 914.4 m) and high (> 1, 524 m) elevations in open, forest edge, and riparian habitats. Additionally, habitat suitability was modeled for a common species, big brown bat (Eptesicus fuscus). The study started May 27th 2019, and sites were monitored biweekly until October 2nd 2019. Six species and one genus were recorded during the study. Species from the Myotis genus were grouped together because of similar call characteristics. Results show that species were significantly more …
Land Use Influences Along Elevation Gradient On Macroinvertebrate Communities, Brittany Sprout
Land Use Influences Along Elevation Gradient On Macroinvertebrate Communities, Brittany Sprout
Electronic Theses and Dissertations
Land use activities have caused disturbances that affect the quality of freshwater ecosystems worldwide. How the influences of land use along an environmental gradient and the associated environmental variables that may influence stream diversity and function is unclear. We address these issues by studying biodiversity, abundance, and functional diversity of macroinvertebrates across different land types along a gradient in Colorado, USA. We also address how diversity may change along an elevation gradient by analyzing previously published macroinvertebrate research. We found evidence that land use and disturbance are stronger explanations of changes in macroinvertebrate communities, rather than elevation. Functional trait patterns …
