Effects Of Stream Permanence On The Stoneflies (Plecoptera) Of The Mammoth Cave Region, Taylor Mcroberts
Effects Of Stream Permanence On The Stoneflies (Plecoptera) Of The Mammoth Cave Region, Taylor Mcroberts
Masters Theses & Specialist Projects
Stoneflies (Plecoptera) are often associated with cold perennial streams, but many species also inhabit intermittent streams that experience reduced or lack of flow during summer and autumn. In this study the influence of stream permanence on stonefly assemblage composition and spatial distribution in the Mammoth Cave region, Kentucky, USA, was addressed based on a 14 month sampling regime from the fullest range of stream sizes and habitable flow regions available. Adult stoneflies were collected monthly at Mammoth Cave National Park and the Western Kentucky University Green River Preserve. Collections were done from December 2018–October 2019 using a standard timed protocol …

Mahurin Honors College Capstone Experience/Thesis Projects
As anthropogenic influences take an ever-increasing toll on the environment, understanding how environmental change affects species is paramount. Concern regarding decline in amphibian populations has spurred research examining the effects of habitat change on the dynamics of populations at landscape levels. One important goal is to understand how gene flow among populations is affected by changes in habitat. Biologists need to consider the relationship between gene flow and habitat alterations so that movements among individual breeding ponds can be maintained over time, reducing risk of local extinction events. This study focuses on patterns of gene flow among thirteen populations of …
