Background: Product safety testing typically involves lethal toxicity assessments, which likely miss long- term health impacts. Optimizing long-term product safety is critical for widespread chemical use. The obesity epidemic exemplifies a condition based

Organohalogen contaminants and vitamins in Northern Fur Seals (Callorhinus ursinus) collected during subsistence hunts in Alaska

During native subsistence hunts from 1987 to 2007, blubber and liver samples from 50 subadult male northern fur seals (Callorhinus ursinus) were collected on St. Paul Island, Alaska. Samples were analyzed for legacy persistent organic pollutants (POPs)

MICROARRAY APPLICATIONS TO UNDERSTAND THE IMPACT OF EXPOSURE TO ENVIRONMENTAL CONTAMINANTS IN WILD DOLPHINS (Tursiops truncatus).

Author(s)
Annalaura Mancia, Luigi Abelli, John Kucklick, Teresa Rowles, Randall Wells, Brian C. Balmer, Aleta Hohn, John Baatz, James Ryan
It is increasingly common to monitor the marine environment and establish geographic trends of environmental contamination by measuring contaminant levels in animals from higher trophic levels. The health of an ecosystem is largely reflected in the health

Influence of tissue, age, and environmental quality on global levels of genomic methylation in the American alligator (Alligator mississippiensis)

January 7, 2014
Author(s)
Benjamin B. Parrott, John Bowden, Satomi Kohno, Jessica A. Cloy-McCoy, Jacqueline T. Bangma, Thomas R. Rainwater, Phillip M. Wilkinson, John Kucklick, Louis J. Guillette
Epigenetic modifications are key mediators of the interactions between the environment and an organism's genome. DNA methylation represents the best-studied epigenetic modification to date and is known to play key roles in regulating transcriptional

The Distribution and Stratification of Persistent Organic Pollutants and Fatty Acids in Bottlenose Dolphin (Tursiops truncatus) Blubber

October 1, 2013
Author(s)
Debra Ellisor, William McLellan, Heather Koopman, Wayne E. McFee, Lori Schwacke, John Kucklick
Blubber has been used for decades to monitor the exposure of marine mammals to persistent organic pollutants (POPs). However, little is known regarding POP variability as a function of blubber depth and across the body of the animal. However, such sampling

Persistent Organic Pollutants and Vitamins in Northern Fur Seals (Callorhinus ursinus) Collected from St. Paul Island, Alaska as Part of the Alaska Marine Mammal Tissue Archival Project

August 1, 2013
Author(s)
John Kucklick, Jessica Reiner, Michele M. Schantz, Jennifer Lynch, Jennifer Hoguet, Kate Rimmer, Rebecca Pugh, Jody Rhoderick, Jennifer Ness, Paul R. Becker, Danielle Peterson
Liver and blubber samples from 50 juvenile male northern fur seals (Callorhinus ursinus) were collected on St. Paul Island from four different seal rookeries between 1987 and 2007. Samples were analyzed for vitamins and for both legacy and current-use

Spatial and temporal trends of persistent organic pollutants and mercury in beluga whales (Delphinapterus leucas) from Alaska

January 24, 2013
Author(s)
Jennifer Hoguet, Jessica Reiner, Jennifer Lynch, John Kucklick, Colleen E. Bryan Sallee, Amanda Moors, Rebecca Pugh, Paul R. Becker
Remote locations, such as the Arctic, are often sinks for persistent contaminants which can ultimately bioaccumulate in local wildlife. Assessing temporal contaminant trends in the Arctic is important in understanding whether restrictions on legacy

Interlaboratory Comparison Study to Support the Deepwater Horizon Natural Resource Damage Assessment: Description and Results for QA11Blood01- PAHs, PAH Metabolites, and DOSS in Solution and Blood

July 12, 2012
Author(s)
John R. Kucklick, Michele M. Schantz
To support natural resource damage assessment (NRDA) in response to the Deepwater Horizon (DWH) oil spill in the Gulf of Mexico, a large number of samples were collected from protected species including marine mammals and sea turtles. Analysis of these

Perfluoroalkyl Contaminants in Plasma of Five Sea Turtle Species: Comparisons in Concentration and Potential Health Risks

May 23, 2012
Author(s)
Jennifer M. Lynch, Lily Ngai, Joanne Braun-McNeill, Larry Wood, Kelly Stewart, Steven O'Connell, John R. Kucklick
We compared the plasma concentration of 13 perfluorinated contaminants (PFCs) in five sea turtle species. Perfluorooctane sulfonate (PFOS) was predominant in most species, except hawksbills had higher concentrations of perfluorononanoate. Excluding
