Community Structure And Dynamics Of Benthic Macroinvertebrates In A Recreated Headwater Stream System On A Valley Fill In A Retrofitted Watershed Located In The Appalachian Coalfields Of Southeastern Kentucky (U.S.A.), Steven W. Bailey
Electronic Theses and Dissertations
The extraction of coal from steep-gradient surface mining sites such as in the Appalachian Coalfields of the U.S. produces excess debris that is often placed in adjacent valleys resulting in the creation of valley fills. Not only are headwater streams buried in the process, but watershed functions are either destroyed outright, or become fragmented and disconnected from adjacent ecosystems resulting in adverse effects to downstream biological communities. In this dissertation, the dynamics of stream macroinvertebrate community structure, composition, diversity, and biotic integrity are assessed at a “proof of concept” stream system recreated on a retrofitted valley fill. For comparison, two …
Plant Community Responses To The Removal Of Lonicera Maackii From An Urban Woodland Park., Elihu H. Levine
Plant Community Responses To The Removal Of Lonicera Maackii From An Urban Woodland Park., Elihu H. Levine
Electronic Theses and Dissertations
Impacts of Lonicera maackii on native forest communities have been widely researched, but long-term responses of plant communities to the removal of this exotic shrub have not been extensively evaluated. The Louisville Olmsted Parks Conservancy removes exotic shrubs and vines to restore ecological processes and native species in the woodlands of Cherokee Park. Paired-plots were established in 2008 to gather baseline herb, vine, tree, and shrub community data. Honeysuckle was removed from one plot of each pair in 2009 and community data were gathered again in 2013. Native herb cover and richness, vine cover, and tree sapling abundance increased where …
