Annual Variation In Timing, Orientation And Effects Of Weather On Jefferson Salamander (Ambystoma Jeffersonianum) And Spotted Salamander (Ambystoma Maculatum) Movements In Central Kentucky, Christopher James St. Andre
Annual Variation In Timing, Orientation And Effects Of Weather On Jefferson Salamander (Ambystoma Jeffersonianum) And Spotted Salamander (Ambystoma Maculatum) Movements In Central Kentucky, Christopher James St. Andre
Online Theses and Dissertations
Annual variation in temporal and spatial patterns of amphibian migration and dispersal are poorly understood. To address this issue, a circular drift fence was installed around an ephemeral pond at the Central Kentucky Wildlife Management Area, Madison County, Kentucky. The pond was checked daily for salamander movements from 17 January 2010 to 26 September 2010 and from 26 January 2011 to 3 August 2011, which corresponded to the activity season. Weather variables examined in relation to amphibian movements included barometric pressure, cumulative precipitation, temperature and relative humidity. Several species used the ephemeral pond during the study but few successfully reproduced. …
Land Snail Species Diversity And Composition Between Different Forest Disturbance Regimes In Central And Eastern Kentucky Forests, Daniel Douglas
Land Snail Species Diversity And Composition Between Different Forest Disturbance Regimes In Central And Eastern Kentucky Forests, Daniel Douglas
Online Theses and Dissertations
Land snails are cornerstone organisms that contribute to properly functioning ecosystems. However, habitat loss and destruction have led to these organisms being one of the most imperiled groups on the planet. Due to their relatively sedentary nature, land snails can be susceptible to anthropogenic disturbance and habitat fragmentation. Because of this, old-growth forests have the potential for being premiere habitat for these organisms, and snails have the potential to be good indicators of old-growth habitats. This study compared land snail species diversity and community composition in old-growth and second-growth forests in the Inner Bluegrass, Cumberland Plateau, and Pine Mountain ecoregions …
Efficacy Of Constructed Wetlands Of Various Depths For Natural Amphibian Community Conservation, Andrea Nicole Drayer
Efficacy Of Constructed Wetlands Of Various Depths For Natural Amphibian Community Conservation, Andrea Nicole Drayer
Online Theses and Dissertations
Wetlands provide critical habitat for a diverse group of amphibians and provide important ecosystem functions and services to humans. Despite this, most natural wetlands have been lost to land use practices. Consequently, constructing wetlands has become a common practice to mitigate for removed wetlands and to manage for wildlife. There were three primary objectives of this research: 1) to examine whether or not constructed wetlands located on ridge tops in eastern Kentucky in the Daniel Boone National Forest (DBNF) had amphibian communities comparable to natural ephemeral wetlands, 2) to examine amphibian predator-prey relationships within the constructed wetlands, and 3) to …
Effect Of Nestling Sex Ratio On The Provisioning Behavior Of Adult Eastern Bluebirds (Sialia Sialis), Barbara Ellen Kieffer
Effect Of Nestling Sex Ratio On The Provisioning Behavior Of Adult Eastern Bluebirds (Sialia Sialis), Barbara Ellen Kieffer
Online Theses and Dissertations
To maximize reproductive success, parents may, in some cases, differentially invest in sons and daughters, i.e., sex-biased parental investment. Preferential provisioning behavior has been reported in one population of Eastern Bluebirds (Sialia sialis) and attributed to local resource competition. To better understand this behavior, I studied the provisioning behavior of Eastern Bluebirds in Madison County, Kentucky, in 2004. I experimentally manipulated brood sex ratios in 24 bluebird nests, creating female-biased (N = 8), male-biased (N = 5), and control (N = 11) nests. Following manipulation, nests were video-taped to record adult provisioning behavior. Among experimental broods, the provisioning rates …
A Post-Restoration Assessment Of The Fishes And Macroinvertebrates Of Mill Branch, Knox County, Kentucky, With Emphasis On The Blackside Dace (Chrosomus Cumberlandensis), Dwayne Kevin Merrill
A Post-Restoration Assessment Of The Fishes And Macroinvertebrates Of Mill Branch, Knox County, Kentucky, With Emphasis On The Blackside Dace (Chrosomus Cumberlandensis), Dwayne Kevin Merrill
Online Theses and Dissertations
The first stream habitat restoration project for the federally threatened blackside dace, Chrosomus cumberlandensis (Starnes and Starnes), was initiated in fall 2005 on Mill Branch, a small headwater stream located in the Upper Cumberland River basin, Knox County, Kentucky. The lower 700 meters of Mill Branch were restored through construction of a new, stable channel with specially designed habitat features for blackside dace. In August 2009, the newly restored channel was connected to the mainstem and the old channel was eliminated. A post-restoration survey was conducted on the fishes (with emphasis on the blackside dace) and benthic macroinvertebrate communities, between …
Seasonal Changes In A Eutrophic Lake, Wilgreen Lake, Madison County, Kentucky, Richard D. Stockwell, Walter S. Borowski
Seasonal Changes In A Eutrophic Lake, Wilgreen Lake, Madison County, Kentucky, Richard D. Stockwell, Walter S. Borowski
EKU Faculty and Staff Scholarship
WilgreenLake (Madison County, Kentucky) covers ~169 acres, formed in 1966 by damming Taylor Fork. The Wilgreen watershed drains residential developments, modified woodlands, cattle pasture, and some industrial/urban areas in the city of Richmond. The lake is deemed “nutrient impaired” by the EPA.
Our main objective is to document the seasonal changes in key lake parameters from summer stratification through fall overturn over 4 months of sampling, August through November, 2008. We collect temperature, oxygen, pH, and conductivity data from 19 stations at depth intervals of 1 meter using an YSI multi-probe. Concurrent with collecting these framework data, we take water …
