Genetic Diversity & Connectivity Of Chasmanthium Latifolium (Poaceae) In Pennsylvania & The Effect On Conservation Status Of A Rare Species, Jonathan D. Hayes
Genetic Diversity & Connectivity Of Chasmanthium Latifolium (Poaceae) In Pennsylvania & The Effect On Conservation Status Of A Rare Species, Jonathan D. Hayes
Honors Theses
Chasmanthium latifolium (Michx.) Yates (Poaceae) is a loosely colonial, rhizomatous, perennial grass species that lives in riparian habitats, making it fittingly referred to as river oats. Native to the southern Midwest and the eastern half of the United States, C. latifolium reaches the northeastern edge of its range in Pennsylvania. Within Pennsylvania, eleven extant C. latifolium populations are found along four waterways: the Monongahela River, the Susquehanna River, and two tributaries to the Susquehanna River. This limited state distribution exhibits an east-west disjunct distribution, where western populations are largely separated from eastern populations with one centrally located population. Between the …
Genetic Estimates Of The Number Of Breeding Adults In Alligator Gar From The Choke Canyon Reservoir, Texas, E. Blayne Newsome
Genetic Estimates Of The Number Of Breeding Adults In Alligator Gar From The Choke Canyon Reservoir, Texas, E. Blayne Newsome
Honors Theses
Alligator gar were historically found across the coastal drainages of the Gulf of Mexico and up into the Mississippi River basin. However, their populations are experiencing decline in many portions of their range. Texas seems to have large populations of alligator gar, but state resource officers are seeking to better understand its biology so as to provide appropriate management recommendations to maintain the recreational fishery. In this study, I used genetic techniques to examine a cohort of 144 juvenile alligator gar collected in 2016 in the Choke Canyon Reservoir. By estimating the effective number of breeders and number of spawning …
Using Unmanned Aerial Vehicle Technology To Enhance Conservation Biology Research, Ann Briggs
Using Unmanned Aerial Vehicle Technology To Enhance Conservation Biology Research, Ann Briggs
Honors Theses
This study examined the most effective ways to utilize unmanned aerial vehicles (UAV) for wildlife conservation. More specifically, a UAV platform was created that can perform multiple data collection tasks by utilizing interchangeable modules. The prototype produced in this study has the capability to perform many tasks through the use of interchangeable modules. These tasks include, but are not limited to aerial surveys and collection of biological samples. This innovative technology will provide invaluable assistance to conservation efforts by reducing research and subject injury or death while maximizing efficiency. The modular design of the prototype was developed for retail to …
