Spatial distribution of bottlenose dolphins (Tursiops truncatus) inferred from stable isotopes and priority organic pollutants

February 15, 2012

Rachel Wilson, John Kucklick, Brian C. Balmer, Randall Wells, Jeffery Chanton, Doug Nowacek
Differences in priority organic pollutants (POPs), analyzed by gas chromatography-mass spectrometry, and stable isotope ratios (δ¹³C, δ³⁴S, and δ¹⁵N; analyzed by isotope ratio-mass spectrometry), divide 77 bottle- nose dolphins (Tursiops truncatus) from

Trophic Magnification Factors: Impact of Ecology, Ecosystem and Study Design

Katrine Borga, Karen Kidd, Olof Berglund, Jason Conder, Frank Gobas, John Kucklick, Olaf Malm, Dave Powell, Derek Muir
Recent reviews by researchers from academia, industry and government have revealed that the criteria used by the Stockholm Convention on persistent organic pollutants (POPs) under the United Nations Environmental Programme are unable to identify the actual

Anemia, Hypothyroidism and Immune Suppression Associated with Polychlorinated Biphenyl Exposure in Bottlenose Dolphins (Tursiops truncatus)

John Kucklick, Lori Schwacke, Eric Zolman, Brian C. Balmer, Sylvain De Guise, Clay George, Jennifer Hoguet, Steve Lamb, Milton Levin, J. L. Litz, W E. McFee, Ned Place, Forrest Townsend, Teresa Rowles, Randall Wells, Aleta Hohn
Background: Polychlorinated biphenyls (PCBs) and other legacy organohalogens are often monitored in marine mammals both to understand health risks for populations of these protected species and as an indication of marine food web contamination. Bottlenose

Bottlenose Dolphins as Indicators of Persistent Organic Pollutants in Waters Along the US East and Gulf of Mexico Coasts

May 15, 2011
Author(s)
John R. Kucklick, Lori Schwacke, Randall S. Wells, Aleta Hohn, Aurore Guichard, Jennifer Yordy, Larry Hansen, Eric Zolman, Rachel Wilson, J. L. Litz, Doug Nowacek, Teresa Rowles, Rebecca S. Pugh, Brian C. Balmer, Carrie Sinclair, Patricia Rosel
Persistent organic pollutants (POPs) including legacy POPs (PCBs, chlordanes, mirex, DDTs, HCB, and dieldrin) and polybrominated diphenyl ether (PBDE) flame retardants were determined in 300 blubber biopsy samples from coastal and near shore/estuarine male

Relationship between Persistent Organic Pollutants (POPs) and Ranging Patterns in Common Bottlenose Dolphins (Tursiops truncatus) from Coastal Georgia, USA

May 2, 2011
Author(s)
John Kucklick, Brian C. Balmer, Lori Schwacke, Randall Wells, Clay George, Jennifer Hoguet, Suzanne Lane, Anthony Martinez, William McLellan, Patricia Rosel, T K. Rowles, Kate Sparks, Todd Speakman, Eric Zolman, D A. Pabst
Bottlenose dolphins (Tursiops truncatus) are apex predators and common in coastal southeastern U.S. waters; as such they are indicators of persistent organic pollutants (POPs) in coastal ecosystems. The concentrations of POPs and patterns of specific

Geographical variation of Persistent Organic Pollutants in eggs of threatened loggerhead sea turtles (Caretta caretta) from Southeastern USA

April 4, 2011
Author(s)
Jennifer M. Lynch, Juan Alava, Jeanette Wyneken, Larry Crowder, Geoffrey Scott, John R. Kucklick
Persistent organic pollutants (POPs) are a recognized man-made threat to sea turtle populations, but the uncertainty surrounding exposure and sensitivity of sea turtles to contaminants is great and makes decision making difficult for conservation managers

Specimen Banking for Marine Animal Health Assessment

November 8, 2010
Author(s)
John R. Kucklick, Rebecca S. Pugh, Paul R. Becker, Jennifer M. Lynch, Russell D. Day, Jennifer Yordy, Amanda J. Moors, Steven J. Christopher, Colleen E. Bryan Sallee, Lori Schwacke, Randall S. Wells, Brian C. Balmer, Aleta Hohn, Teri Rowles
Marine animals are faced with health threats including disease and accumulation of toxic pollutants. There are several efforts in the USA seeking to relate health metrics to the exposure of marine animals to pollution, biotoxins, and disease. The National

Partitioning of Persistent Organic Pollutants (POPs) between Blubber and Blood of Wild Bottlenose Dolphins: Implications for Biomonitoring and Health

June 15, 2010
Author(s)
Jennifer Yordy, John R. Kucklick, Randall S. Wells, Brian C. Balmer, Lori Schwacke, Teresa Rowles
Biomonitoring of wild cetaceans for persistent organic pollutants (POPs) is heavily reliant on concentrations determined in blubber, and there are few data relating blubber concentrations and levels in blood. Matched blubber and plasma samples (n=56) were

Toxicokinetics, tissue-specific distribution and whole body burden of persistent organic pollutants in the bottlenose dolphin (Tursiops truncatus)

June 1, 2010
Author(s)
Jennifer Yordy, John R. Kucklick, D A. Pabst, William McLellan, Randall S. Wells, Teresa Rowles
The majority of exposure assessments for free-ranging cetaceans focus on contaminant concentrations measured in blubber, and there are few data for other tissues or the factors governing contaminant distribution between tissues. The goal of this study was
