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 …
Analyzing The Phenologic Dynamics Of Kudzu (Pueraria Montana) Infestations Using Remote Sensing And The Normalized Difference Vegetation Index., Faye Peters
Electronic Theses and Dissertations
Non-native invasive species are one of the major threats to worldwide ecosystems. Kudzu (Pueraria montana) is a fast-growing vine native to Asia that has invaded regions in the United States making management of this species an important issue. Estimated normalized difference vegetation index (NDVI) values for the years 2000 to 2015 were calculated using data collected by Landsat and MODIS platforms for three infestation sites in Kentucky. The STARFM image-fusing algorithm was used to combine Landsat- and MODIS-derived NDVI into time series with a 30 m spatial resolution and 16 day temporal resolution. The fused time series was …
Characterization Of Microbial Communities In Karstic Sediments : A Study Of Cave Bacteria In Central Kentucky., Justine Kay Roback 1964-
Characterization Of Microbial Communities In Karstic Sediments : A Study Of Cave Bacteria In Central Kentucky., Justine Kay Roback 1964-
Electronic Theses and Dissertations
Few previous studies have compared microbial communities in subterranean and surface environments. Chemical analyses used to characterize the surface and cave microbial environments indicated limited exchange between surface and subsurface waters. Here, bacterial communities from four distinct cave sediments collected in central Kentucky and adjacent surface streams were compared using a combination of culture and molecular methods. Predictions were that: 1) Cave communities will have unique community structures when compared to those of nearby surface sediments, and 2) Genetic diversity of bacterial communities in cave sediments will be higher than those in nearby surface sediments. Since diversity and community structure …
Life History And Production Of Three Species Of Isopods In Beargrass Creek Louisville, Ky, James A. Eckstein
Life History And Production Of Three Species Of Isopods In Beargrass Creek Louisville, Ky, James A. Eckstein
Electronic Theses and Dissertations
The life history and annual production of the aquatic isopods L. fontinalis, C. intermedia and C. brevicaudus in a spring stream, Beargrass Creek, Louisville, Kentucky was studied. Reproductive activity was observed with the greatest intensity in the spring months from March to May. Smaller secondary peaks for recruitment of young were seen in the fall months for L. fontinalis and C. intermedia. Brood size for the three isopods was compared by linear regression. The mean annual biomass for the three isopods ranged from 0.67 g/m2 for C. intermedia, 0.83 g/m2 for C. brevicaudus to 2.1 g/m2 for L. fontinalis. Annual …
Distribution Of The Herpetofauna Of Kentucky., Symoine Kamin Laufe
Distribution Of The Herpetofauna Of Kentucky., Symoine Kamin Laufe
Electronic Theses and Dissertations
Although the herpetofauna of Kentucky is extensive and varied. it has received much less attention than that of most other states. Many herpetologists have reported on various phases of the state's amphibians and reptiles, but for the most part these reports are discrete, either pertaining to a collection, or a generic or specific study. Hence, there is no single adequate work which aptly describes the herpetology of Kentucky as a whole. When one realizes the keystone position of Kentucky in relation to northern and southern forms, the need of a zoogeographical summary of the state becomes even more apparent. Therefore, …
