Spatiotemporal Variation Of An Eastern Tropical Pacific Pelagic Community Assessed With Free-Drifting Bruvs, Tyler Stephen Plum
Spatiotemporal Variation Of An Eastern Tropical Pacific Pelagic Community Assessed With Free-Drifting Bruvs, Tyler Stephen Plum
All HCAS Student Capstones, Theses, and Dissertations
Information about pelagic community diversity and ecology generally lags far behind that of coastal communities, and largely derives from fisheries data that do not reflect small and non-target species. We describe spatiotemporal vertebrate species diversity and variability over a 3,486 km2 area of highly productive pelagic marine ecosystem in Pacific Panama using drifting baited remote underwater video stations (BRUVS), a non-invasive fishery-independent sampling technique. We observed 26 taxa from 17 families, including 1 mammal, 3 reptile, 5 elasmobranch, and 17 teleost species. Community assemblages differed on and off the continental shelf and between wet (April – December) and dry …
The Age And Growth Of The Yellow Stingray (Urobatis Jamaicensis) In Southeast Florida, Jessica Schieber
The Age And Growth Of The Yellow Stingray (Urobatis Jamaicensis) In Southeast Florida, Jessica Schieber
All HCAS Student Capstones, Theses, and Dissertations
The yellow stingray, Urobatis jamaicensis (Cuvier 1816), is a coastal species that has limited known life-history information, especially regarding their age and growth patterns. Age estimates were assigned by counting band-pairs deposited on the vertebral centrum of stingrays caught between 2003 and 2019 (n = 195). Marginal increment analysis of different size classes was used to validate age estimates, with the largest class having verified annual band deposition (ANOVA, F(9,7), P = 0.029). Age estimates ranged between females, and rates, but females attained larger sizes with the largest observed DW being 241-mm and 216-mm for females and males, respectively. …
