The Population Genetics Of The Wood Frog, Rana Sylvatica, Across Its Geographic Range, Tina M. Squire
Theses and Dissertations
This study aimed to determine the level of genetic variation across the continental-wide range of the wood frog, Rana sylvatica. Levels of genetic differentiation between sampled populations were investigated as was the possible locations of glacial refugia for this species. DNA microsatellites were used as the genetic marker. This study found significant genetic differentiation across the geographic range of Rana sylvatica that increased with geographic distance. In addition three likely glacial refugia, Alaska, New York and the southern Appalachians, were identified.
A subset of the populations used in the geographic range study was used to investigate the patterns at a …
Implications Of Introduced Mule Deer On Santa Catalina Island, California : Their Impacts, Population Ecology, And Management, Thad A. Manuwal
Implications Of Introduced Mule Deer On Santa Catalina Island, California : Their Impacts, Population Ecology, And Management, Thad A. Manuwal
Theses and Dissertations
A small group of mule deer were introduced to Santa Catalina Island in the early
1930s. The mule deer population increased through the 1940s and 1950s and remains widespread and abundant today. Large browsing ungulates are not native to Santa Catalina Island and there is concern that nonnative mule deer are damaging endemic trees and shrubs on the island when foraging. This study was designed to develop quantitative information on diets, foraging behavior, movements, and population biology of mule deer on Catalina Island.
Diet analysis indicated mule deer are consuming a wide variety of native and
endemic plants found on …
