Identification of Isethionic Acid and Other Small Molecule Metabolites of Fragilariopsis cylindrus with Nuclear Magnetic Resonance

July 8, 2012
Author(s)
Dan Bearden, Arezue F. Boroujerdi, Peter A. Lee, Giacomo R. DiTullio, Michael G. Janech, Sarah B. Vied
Nuclear magnetic resonance (NMR)-spectroscopy has been used to obtain metabolic profiles of the polar diatom Fragilariopsis cylindrus, leading to the identification of a novel metabolite in this organism. Initial results from an ongoing metabolomics study

Environmental Metabolomics

March 15, 2012
Author(s)
Daniel W. Bearden
The application of metabolomics in the field of environmental science or ecology, which has developed based substantially on NMR spectroscopic approaches, is a fast paced, rapidly developing field which seems to be poised to help re-frame the discussion of

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

February 15, 2012
Author(s)
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

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

May 25, 2011
Author(s)
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

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

SEABIRD TISSUE ARCHIVAL AND MONITORING PROJECT: Project Overview, and Updated Protocols for Collecting and Banking Seabird Eggs

July 29, 2010
Author(s)
Lauren B. Rust, Rebecca S. Pugh, Amanda J. Moors, Stacy S. Schuur, David G. Roseneau, Paul R. Becker
The Seabird Tissue and Archival Monitoring Project (STAMP) is a collaborative effort by the U.S. Fish and Wildlife Service (USFWS), the Alaska Maritime National Wildlife Refuge (AMNWR), and the National Institute of Standards and Technology (NIST) to

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

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
