Long-Term Study On The Population Ecology Of Urban Queen Snakes (Regina Septemvittata) In Central Virginia, Rachel Beiler
Long-Term Study On The Population Ecology Of Urban Queen Snakes (Regina Septemvittata) In Central Virginia, Rachel Beiler
Senior Honors Theses
As parts of the world are becoming more urbanized, species living in urban habitat fragments are more at risk of extirpation. We conducted, in an urban environment, a 12-year (2008-2019) mark/recapture study on a Queen snake (Regina septemvittata) population in Rock Castle Creek, Lynchburg, VA to determine population viability. Ninety-nine individual Queen snakes were marked to determine stable population estimates (range 3 - 43 snakes) and an annual survival rate of 52%. Our research found that despite the challenges of urban living, this population is stable and similar to rural Queen snake population studies. Certain life-history traits are …
The Impact Of Ambrosia Trifida (Giant Ragweed) On Native Prairie Species In An Early Prairie Restoration Project, Krisztian Megyeri
The Impact Of Ambrosia Trifida (Giant Ragweed) On Native Prairie Species In An Early Prairie Restoration Project, Krisztian Megyeri
Senior Honors Theses
As the ecological importance of prairies is becoming more recognized, the number of prairie restoration projects is increasing worldwide. One of the major challenges in restoring any disturbed ecosystem is the successful establishment of native species at the expensive of invasive species. While some weedy species are gradually replaced as other, more desired, species become established, there are invasive species that, due to their level of dominance, may out-compete native species indefinitely. The objectives of this study were 1) to quantify the impact of Ambrosia trifida (giant ragweed) on the plant community of a newsly established prairie, 2) to assess …
