Journal ArticleDOI
Bottlenose Dolphins as Marine Ecosystem Sentinels: Developing a Health Monitoring System
Randall S. Wells,Howard L. Rhinehart,Larry J. Hansen,Jay C. Sweeney,Forrest I. Townsend,Rae Stone,David R. Casper,Michael D. Scott,Aleta A. Hohn,Teri Rowles +9 more
TL;DR: A team of marine mammal veterinarians and biologists worked together to develop an objective, quantitative, replicable means of scoring the health of dolphins, based on comparison of 19 clinically diagnostic blood parameters to normal baseline values, which appears to roughly reflect dolphin health.
U.S. Atlantic and Gulf of Mexico marine mammal stock assessments--1999
Gordon T. Waring,Debra L. Palka,Phillip J. Clapham,Steven L. Swartz,Marjorie C. Rossman,Larry J. Hansen,Kathryn D. Bisack,Keith D. Mullin,Randall S. Wells,Daniel K. Odell,Neilo B. Barros +10 more
TL;DR: The National Marine Fisheries Service (NMFS), 166 Water St., Woods Hole, MA 02543 as discussed by the authors, and the National Oceanic and Atmospheric Administration (NOAA), 75 Virginia Beach Dr., Miami, FL 33149
Journal ArticleDOI
Physical habitat of cetaceans along the continental slope in the northcentral and western gulf of mexico
Randall W. Davis,G. S. Fargion,N. May,T. D. Leming,M. Baumgartner,W. E. Evans,Larry J. Hansen,Keith D. Mullin +7 more
TL;DR: Risso's dolphins and short-finned pilot whales occurred along the upper slope and, as a subgroup, were significantly different from striped dolphins, Mesoplodon spp.
Journal ArticleDOI
Probabilistic risk assessment of reproductive effects of polychlorinated biphenyls on bottlenose dolphins (Tursiops truncatus) from the Southeast United States Coast.
Lori H. Schwacke,Lori H. Schwacke,Eberhard O. Voit,Larry J. Hansen,Randall S. Wells,Greg B. Mitchum,Aleta A. Hohn,Patricia A. Fair +7 more
TL;DR: Risk analyses for dolphin populations near Beaufort, Sarasota, and Matagorda Bay indicate a high likelihood that reproductive success, primarily in primiparous females, is being severely impaired by chronic exposure to PCBs.
Journal ArticleDOI
Geographic variation in polychorinated biphenyl and organochlorine pesticide concentrations in the blubber of bottlenose dolphins from the US Atlantic coast.
Larry J. Hansen,Lori H. Schwacke,Greg B. Mitchum,Aleta A. Hohn,Randall S. Wells,Eric S. Zolman,Patricia A. Fair +6 more
TL;DR: The measured PCB concentrations, although lower than those reported for stranded animals from the 1987/1988 epizootic along the United States mid-Atlantic coast, are sufficiently high to warrant concern for the health of dolphins from the sampled populations, particularly the animals near Charleston and Beaufort.
