Population Structure Of A Federally Endangered Plant (Astragalus Jaegerianus Munz, Fabaceae) With Limited Range Using Microsatellites, Sueann Neal
Electronic Theses, Projects, and Dissertations
Studies on population genetics examine the relationship and effects of population structure, migration, gene flow and demographic history, and are therefore important in the conservation of endangered species. Astragalus jaegerianus, a critically federally endangered species found in a geographically restricted range is investigated to determine population structure and genetic variation. Previous research on A. jaegerianus focused on DNA sequence data for cpDNA and nrDNA showed no variation. Further research on A. jaegerianus utilizing AFLP’s on the whole genome indicated substantial gene diversity and population structure consistent with geographically widespread species. AFLP research is a cost-effective process to identify levels …
Hunting Contests In New York State, Tyler Caffrey
Hunting Contests In New York State, Tyler Caffrey
Honors College Theses
The world is currently in a biodiversity crisis and hunting contests cannot continue. Hunting contests are not legitimate wildlife management tools, but exist for entertainment and killing for a prize. Many of the species targeted can be killed without bag limits. Additionally, many wildlife management practices are retroactive, meaning they are in response to an issue. Within New York State, these contests are not regulated by the NYSDEC beyond adhering to hunting regulations. With these factors together, animals targeted by these contests can be hunted to a detrimental point, and then management agencies would step in. These contests face significant …

Genomic Evidence Suggests Further Changes Of Butterfly Names, Jing Zhang, Qian Cong, Jinhui Shen, Pal A. Opler, Nick V. Grishin
The Taxonomic Report of the International Lepidoptera Survey
Further genomic sequencing of butterflies by our research group expanding the coverage of species and specimens from different localities, coupled with genome-scale phylogenetic analysis and complemented by phenotypic considerations, suggests a number of changes to the names of butterflies, mostly those recorded from the United States and Canada. Here, we present evidence to support these changes. The changes are intended to make butterfly classification more internally consistent at the genus, subgenus and species levels. That is, considering all available evidence, we attempt to assign similar taxonomic ranks to the clades of comparable genetic differentiation, which on average is correlated with …

Diatom Voucher Flora And Comparison Of Collection Methods For Biodiversity Hotspot Upper Three Runs Creek, Katie M. Johnson
Biology Theses
Surface freshwater is a scarce resource. Due to the scarcity and necessity of this resource, it is imperative that its quality is routinely monitored. One way of monitoring water quality is through biological assessments, which include examining algal assemblages. Regionally, little remains known of algal taxa in the southeastern United States. In the past, the Academy of Natural Sciences of Philadelphia (ANSP) conducted biological assessments along the Savannah River finding Gomphonema parvulum (Kützing) Kützing 1849 to be a dominant taxon rendering assessments inconclusive. Recent studies have provided evidence that species complexes and semi-cryptic taxa have been identified within the Gomphonema …

Invasive Rat Establishment And Changes In Small Mammal Populations On Caribbean Islands Following Two Hurricanes, Aaron B. Shiels, Claudia D. Lombard, Laura Shiels, Zandy Hillis-Starr
USDA Wildlife Services: Staff Publications
Invasive mammals, particularly black rats (Rattus rattus), house mice (Mus musculus), and mongoose (Herpestes auropunctatus) are established on many tropical islands and threaten natural resources such as native birds, sea turtles, lizards, invertebrates, and plants. St. Croix (U.S. Virgin Islands, Caribbean) has a diversity of natural resources being protected from invasive mammals by U.S. conservation agencies. Sandy Point National Wildlife Refuge and Buck Island Reef National Monument receive among the highest density of nesting sea turtles in the region, including annual nesting populations of 50e250 leatherbacks (Dermochelys coriacea), 25e80 hawksbills (Eretmochelys imbricata), and 100e250 green turtles (Chelonia mydas). Buck Island …
