Life history as a source of variation for persistent organic pollutant (POP) patterns in a bottlenose dolphin community resident to Sarasota Bay, FL

April 1, 2010
Author(s)
Jennifer Yordy, John R. Kucklick, Randall S. Wells, Brian C. Balmer, Lori Schwacke, Teresa Rowles
Bottlenose dolphins (Tursiops truncatus) are prone to accumulating complex mixtures of persistent organic pollutants (POPs). While variations in POP patterns have been previously observed for populations separated across regional and fine-scale geographic

Marine Mammal Blubber Reference and Control Materials for Use in the Determination of Halogenated Organic Compounds and Fatty Acids

March 19, 2010
Author(s)
John R. Kucklick, Michele M. Schantz, Rebecca S. Pugh, Barbara J. Porter, Dianne L. Poster, Paul R. Becker, Teresa Rowles, Stefan D. Leigh, Stephen A. Wise
The National Institute of Standards and Technology (NIST) has a diverse collection of control materials derived from marine mammal blubber, fat, and serum. Standard Reference Material (SRM) 1945 Organics in Whale Blubber was recertified for polychlorinated

Description & Results of the 2007 NIST/NOAA Interlaboratory Comparison Exercise Program for Organic Contaminants in Marine Mammal Tissues

March 1, 2010
Author(s)
John Kucklick, Rebecca Pugh, Aurore Guichard, Michele M. Schantz, Stephen Wise, Teresa Rowles
The National Institute of Standards and Technology (NIST), in support of the National Oceanic & Atmospheric Administrations Marine Mammal Health and Stranding Response Program (NOAA/MMHSRP), conducts annual interlaboratory comparison exercises for the

Metabolomic Analysis of Atlantic Blue Crab, Callinectes sapidus, Hemolymph Following Oxidative Stress

January 20, 2010
Author(s)
Tracey Johnston, Dan Bearden, Arezue Boroujerdi, David A. Stancyk, Lindy Thibodeaux, Karen G. Burnett, Louis E. Burnett
The Atlantic blue crab, Callinectes sapidus, is an economically, ecologically and recreationally valuable decapod crustacean that inhabits estuaries along the Atlantic and Gulf coasts of the United States. In their natural environment, blue crabs are

Organohalogen contaminants in blood of Kemp's ridley (Lepidochelys kempii) and green sea turtles (Chelonia mydas) from the Gulf of Mexico

December 9, 2009
Author(s)
Robert R. Swarthout, Jennifer Lynch, Margie Peden-Adams, Andre Landry, Patricia Fair, John Kucklick
The threat that exposure to organohalogen (OH) contaminants poses to endangered populations of Kemp's ridley (Lepidochelys kempii) and green sea turtles (Chelonia mydas) is not well understood, partly because few OH data are available. Blood samples from

NMR-Based Microbial Metabolomics and the Temperature-Dependent Coral Pathogen Vibrio coralliilyticus

September 18, 2009
Author(s)
Daniel W. Bearden, Arezue Boroujerdi, Tracey B. Schock, Alexander Meyers, Elizabeth C. Pollock, Sara Lien Huynh, Maria Vizcaino, Pamela J. Morris
Coral bleaching occurs when the symbioses between coral animals and their zooxanthellae is disrupted, either as part of a natural cycle or as the result of unusual events. The bacterium Vibrio coralliilyticus has been linked to coral disease globally (for

SEABIRD TISSUE ARCHIVAL AND MONITORING PROJECT: Egg Collections and Analytical Results for 2002-2005

Author(s)
David Point, J. I. Garcia Alonso, William C. Davis, Steven J. Christopher, Aurore Guichard, O.F. X. Donard, Paul R. Becker, Gregory C. Turk, Stephen A. Wise
The origins and the processes driving the inadvertent transformations of inorganic mercury (iHg) and methylmercury (MeHg) in cryogenically stored and homogenized fresh-frozen versus freeze-dried biological Standard Reference Materials (SRM) were

Simultaneous Determination of Inorganic Mercury, Methylmercury, and Total Mercury Concentrations in Cryogenic Fresh-Frozen and Freeze-dried Biological Reference Materials

October 1, 2007
Author(s)
David Point, William C. Davis, J. I. Garcia Alonso, Mathilde Monperrus, Steven J. Christopher, O.F. X. Donard, Paul R. Becker, Stephen A. Wise
A double spike speciated isotope dilution (DS-SID) reaction model was developed to study and correct for the inadvertent transformations affecting methylmercury (MeHg), inorganic mercury (iHg) and total mercury (HgT) measurements in biological tissues
