Population Study Of Native And Invasive Turtles In Harrisonburg, Virginia, David R. Weisenbeck
Population Study Of Native And Invasive Turtles In Harrisonburg, Virginia, David R. Weisenbeck
Senior Honors Projects, 2020-current
The Red-eared Slider, Trachemys scripta is an invasive species responsible for declines in turtle species across the world. Trachemys scripta is native to two parts of southern Virginia but the species has been introduced throughout the rest of the state, often related to the release of pet trade animals. This study aimed to identify the extent of Trachemys scripta’s establishment and impact on native species in Harrisonburg, Virginia. Turtles were trapped in a mark-recapture study during the springs and summers of 2018, 2019, and 2020 in four local ponds in Harrisonburg, Virginia. Cormack-Jolly-Seber population models were constructed using data …
Effects Of Harvest Regulations And Post-Release Hooking Mortality On Walleye Populations In South Dakota, Cade Lyon
Electronic Theses and Dissertations
Harvest regulations are commonly implemented to manipulate fisheries stocks. By regulating the size and number of fish that are harvested by anglers, managers are able to meet the goals and needs of regions. However, these management actions come with the potential for negative consequences. Overexploitation due to less restrictive harvest regulations can cause collapses in fisheries populations. In addition, indirect consequences such as hooking mortality brought on by length-based regulations can also be detrimental to populations. In this study, I investigated the effects of various harvest regulations on Walleye populations in three western South Dakota irrigation reservoirs: Angostura, Belle Fourche, …
