Potential Impacts Of The Deepwater Horizon Oil Spill On Large Pelagic Fishes, Sarah Frias-Torres, Charles R. Bostater Oct 2011

Potential Impacts Of The Deepwater Horizon Oil Spill On Large Pelagic Fishes, Sarah Frias-Torres, Charles R. Bostater

Ocean Engineering and Marine Sciences Faculty Publications

Biogeographical analyses provide insights on how the Deepwater Horizon oil spill impacted large pelagic fishes. We georeferenced historical ichthyoplankton surveys and published literature to map the spawning and larval areas of bluefin tuna, swordfish, blue marlin and whale shark sightings in the Gulf of Mexico with daily satellite-derived images detecting surface oil. The oil spill covered critical areas used by large pelagic fishes. Surface oil was detected in 100% of the northernmost whale shark sightings, in 32.8 % of the bluefin tuna spawning area and 38 % of the blue marlin larval area. No surface oil was detected in the …

Successful mating is essentially a consequence of making the right choices at the correct time. Animals use specific strategies to gain information about a potential mate, which is then applied to decision-making processes. Amongst the many informative signals, odor cues such as sex pheromones play important ecological roles in coordinating mating behavior, enabling mate and kin recognition, qualifying mate choice, and preventing gene exchange among individuals from different populations and species. Despite overwhelming behavioral evidence, the chemical identity of most cues used in aquatic organisms remains unknown and their impact and omnipresence have not been fully recognized. In many crustaceans, …


Metals In Sediments And Clams From The Indian River Lagoon, Florida: 2006–7 Versus 1992, John H. Trefry, Robert P. Trocine Jan 2011

Metals In Sediments And Clams From The Indian River Lagoon, Florida: 2006–7 Versus 1992, John H. Trefry, Robert P. Trocine

Ocean Engineering and Marine Sciences Faculty Publications

A 1992 survey of metal concentrations in sediments and clams from the Indian River Lagoon, Florida, was repeated during 2006–7. Concentrations of Cr, Ni, Se and V in sediments were at background values during both surveys with no indication of anthropogenic inputs. Average values for Ag, Cd and Zn in sediments, normalized to Al, were unchanged, but contamination was identified at several locations during both surveys. The proportion of sites with elevated values for sediment Cu, Hg and Pb increased between 1992 and 2006–7 from 22 to 65%, 9 to 35%, and 13 to 39%, respectively, with highest values near …


Distribution Of The Hermit Crabs Clibanarius Vittatus And Pagurus Maclaughlinae In The Northern Indian River Lagoon, Florida: A Reassessment After 30 Years, Christopher J. Kelly, Richard L. Turner Jan 2011

Distribution Of The Hermit Crabs Clibanarius Vittatus And Pagurus Maclaughlinae In The Northern Indian River Lagoon, Florida: A Reassessment After 30 Years, Christopher J. Kelly, Richard L. Turner

The present distribution of two hermit crabs, Clibanarius vittatus and Pagurus maclaughlinae, was assessed for comparison with a study done more than 30 yr ago on decapods of the region. Clibanarius vittatus presently occurs in low or moderate density only at Sebastian Inlet. Retreat of C. vittatus from sites that it formerly occupied is attributed to intolerance of its larvae to low salinities recorded in the lagoon during recent reproductive seasons. Pagurus maclaughlinae remains the most abundant and widespread hermit crab in the lagoon. Its present distribution seems unchanged from the reference study despite prolonged periods, sometimes years, during which …
