Development Of A Novel Environmental Dna (Edna) Tool For Monitoring Vulnerable Freckled Guitarfish, Pseudobatos Lentiginosus, In The Western Central Atlantic, Sarah Toepfer
Honors Theses
Rhino-rays are the most threatened group of elasmobranchs, having experienced widespread declines due to mortalities in fisheries and habitat degradation. Within the Western Central Atlantic, there are two extant species of Rhino-rays, the Critically Endangered Smalltooth Sawfish, Pristis pectinata, and the Vulnerable Freckled Guitarfish, Pseudobatos lentiginosus. Although there is research committed to P. pectinata in this region, less is known about the distribution status of P. lentiginosus. Over the past 50 years, P. lentiginosus have undergone a presumed range contraction in U.S. waters; once found from North Carolina to Texas, and historically common in the north central …
Qpcr Detection Of Early Life History Stage Chrysaora Quinquecirrha (Sea Nettles) In Barnegat Bay, New Jersey, John J. Gaynor, Paul A.X. Bologna, Dena J. Restaino, Christie Barry
Qpcr Detection Of Early Life History Stage Chrysaora Quinquecirrha (Sea Nettles) In Barnegat Bay, New Jersey, John J. Gaynor, Paul A.X. Bologna, Dena J. Restaino, Christie Barry
Department of Biology Faculty Scholarship and Creative Works
The sea nettle Chrysaora quinquecirrha has become abundant in the Barnegat Bay estuary and frequently blooms in warm summer months. Various factors have been attributed to the increasing localized appearance of sea nettles and other jellyfish including eutrophication, overfishing, global warming, construction, and species introduction. Despite its abundance and frequent distribution within estuarine systems, very little work has been done to detect and quantify the early life history stages of this organism. Free-swimming larval stages of C. quinquecirrha can be detected and quantified using a quantitative polymerase chain reaction assay specific for the C. quinquecirrha 16S ribosomal (r)DNA locus of …
