Spatial Heterogeneity Of Soil Nutrients, Nitrogen Dynamics, And Vegetation In A 3rd Order Stream Floodplain In Southwestern West Virginia, David Allen Dick
Spatial Heterogeneity Of Soil Nutrients, Nitrogen Dynamics, And Vegetation In A 3rd Order Stream Floodplain In Southwestern West Virginia, David Allen Dick
Theses, Dissertations and Capstones
Soil processes often exhibit spatial heterogeneity within ecosystems and this heterogeneity may influence community structure. This study was conducted to determine spatial patterns and variability of soil nutrients and plant communities within different vegetation types in a stream floodplain in southwestern West Virginia. One 5-m × 5-m site was established in each of three vegetation/drainage types: pasture (PA), old field (OF), and wetland scar (SC). Pasture and SC sites were located ~25 m apart on flat bottomland; the OF site was located on a moderate slope 6.3 m above bottomland, ~200 m from PA and SC. A 10-m × 1-m …
Developing Methods For The Rapid Molecular Assessment Of Aquatic Microbial Communities, Traci D. Hudson
Developing Methods For The Rapid Molecular Assessment Of Aquatic Microbial Communities, Traci D. Hudson
Theses, Dissertations and Capstones
Molecular investigations of microbial community structure and dynamics involve costly and time-consuming methods. This approach is limiting when rapid assessment and detection of microbial organisms are needed. In aquatic environments, especially freshwater environments which may be used as a water source, rapid detection of pathogenic microbes is essential. Likewise, monitoring for the presence or absence of various functional genes can be used to indicate the type of microbial community present in the environment of interest. Therefore, the aim of this study was to develop and optimize methods necessary for the rapid assessment of freshwater microbial community structure and dynamics. Primers …
An Ecological Study Of The Spotted Salamander, Ambystoma Maculatum, And Jefferson Salamander, A. Jeffersonianum, In West Virginia, Seth J. Myers
An Ecological Study Of The Spotted Salamander, Ambystoma Maculatum, And Jefferson Salamander, A. Jeffersonianum, In West Virginia, Seth J. Myers
Theses, Dissertations and Capstones
The movements of Spotted Salamanders, Ambystoma maculatum, and Jefferson Salamanders, A. jeffersonianum, in and out of an ephemeral wetland in West Virginia were monitored for one breeding season using a drift fence lined with funnel traps. Significant movements of A. jeffersonianum coincided with rainfall and maximum daily air temperatures reaching a minimum of 5° C. Significant movements of A. maculatum coincided with rainfall and maximum daily air temperatures of at least 10° C. A. jeffersonianum preceded A. maculatum to the breeding site. Males of both species preceded females. The mark-recapture estimate of A. maculatum is 67 males and 25 females. …
