The Effect Of Shelterwood-Cut Oak Forestry Practices On Breeding Bird Success, Patrick Lee Collins
The Effect Of Shelterwood-Cut Oak Forestry Practices On Breeding Bird Success, Patrick Lee Collins
Theses & Honors Papers
Populations of breeding birds were studied on two shelterwood-cut oak stands in Buckingham County, Virginia. These two tracts, Harris East and Harris West, were cut in 1996 and a Breeding Bird Census has been conducted on these tracts since 1997. This study is part of an ongoing effort to collect pre-bum data, and document the diversity of avian species utilizing this habitat. The changes in avian species present on the Harris East and Harris West plots is important to know so that the effects of shelterwood-cut forestry practices can be understood better. The data collected showed that, by changing the …
Survey Of Amphibians And Reptiles In Powhatan County, Virginia With Selected Natural History Notes, Jason Daniel Gibson
Survey Of Amphibians And Reptiles In Powhatan County, Virginia With Selected Natural History Notes, Jason Daniel Gibson
Theses & Honors Papers
This thesis establishes baseline data on the herpetofauna that exist in Powhatan county. No systematic study of the amphibians and reptiles in Powhatan county has ever been conducted. The methods used in this survey include hand capture, egg mass observations, road kill collections, and frog call surveys. Documentation of each species collected included measurements, photographs, range maps, and tape recordings.
This survey produced 8 species of salamanders, 11 anurans, 6 turtles, 4 lizards, and 14 snakes. Based on records in the Atlas of Amphibians and Reptiles of Virginia (Mitchell & Reay, 1999), 11 new county records were discovered. This brings …
Development Of A Novel Method For Phenol Detection Using High Performance Thin Layer Chromatography, Danette Young Carlton
Development Of A Novel Method For Phenol Detection Using High Performance Thin Layer Chromatography, Danette Young Carlton
Theses & Honors Papers
The purpose of this study was to develop a more efficient method to test for phenol in both wastewater and non-wastewater. Phenol is a caustic and toxic contaminant that may be present in our water supplies. Phenol is used in various resins, pharmaceuticals, plastics and disinfectants. Environmental Protection Agency methods are available to test for phenol using gas chromatography along with mass spectrometry or flame ionization detection. Each of these methods can be a long, involved process consisting of extraction, many sample injections, and interference problems. This method developed an easier and less complicated approach of testing for phenol in …
Survey Of Exotic Plants Along The Blue Ridge Parkway Between Lower Otter Creek And Sunset Field, Cynthia Diane Gastineau Lane
Survey Of Exotic Plants Along The Blue Ridge Parkway Between Lower Otter Creek And Sunset Field, Cynthia Diane Gastineau Lane
Theses & Honors Papers
The objective of this study was to identify and inventory exotic plant vegetation along a portion of the Blue Ridge Parkway and to determine which species, if any, are invading the adjacent forest and the extent to which these invasions occur. The methods used were derived from those developed by James Akerson at Shenandoah National Park in 1997. Six transects were studied along the Blue Ridge Parkway. Each transect included two to five 100 square meter plots. The first plot of each site was centered at the border between the mowed area and the natural area. The second plots were …
