Author(s)
Jacqueline Bangma, T.C. Guillette, Paige Bommarito, Carla Ng, Jessica Reiner, Andrew Lindstrom, Mark Strynar
Per- and polyfluoroalkyl substances (PFAS) accumulation and elimination in both wildlife and humans is largely attributed to PFAS interactions with proteins, including but not limited to organic anion transporters (OATs), fatty acid binding proteins (FABPs

Author(s)
Jeremie Parot, Andrea Valsesia, Jessica Ponti, Dora Mehn, Rita Marino, Daniela Melillo, Samantha Facchetti, Shinichiro N. Muramoto, R Verkouteren, Vincent Hackley, Pascal Colpo
Plastic particulates in the environment pose an increasing concern for regulatory bodies due to their potential risk to higher organisms (including humans) as they enter the food chain. Nanoplastics (pNP) (defined here as smaller than 1 µm) are

Relationship between the Pacific Decadal Oscillation (PDO) and persistent organic pollutants in sympatric Alaskan seabird (Uria aalge and U. lomvia) eggs between 1999 and 2010

December 31, 2020
Author(s)
Vrinda Kalia, Stacy Schuur, Keith A. Hobson, Howard H. Chang, Lance A. Waller, Steven Hare, Matthew O. Gribble
Although climate change occurs alongside other anthropogenic ecosystem impacts, little is known about how sea-surface temperature variability influences the ecotoxicology of persistent organic pollutants (POPs). We analyzed POP contaminant levels, and

QARTOD - Prospects for Real-Time Quality Control Manuals, How to Create Them, and a Vision for Advanced Implementation

The U.S. Integrated Ocean Observing System (IOOS) Quality Assurance / Quality Control of Real- Time Oceanographic Data (QARTOD) Project marshaled hundreds of volunteer subject matter experts to identify tests to evaluate real-time data quality by

Evaluation of Graded Levels of Soy Oil as a Fish Oil Replacement in High Soy Protein Feeds for Juvenile Red Drum, Sciaenops ocellatus

June 30, 2020
Author(s)
Tracey B. Schock, Aaron Watson, Michael P. Napolitano, John A. Bowden, Jason Frost, Justin Yost, Michael R. Denson
A 9-week feeding trial was conducted with juvenile red drum, Sciaenops ocellatus, to evaluate the use of soy oil as a fish oil replacement. Three primary protein sources (fishmeal - FM, soybean meal - SBM, and soy protein concentrate - SPC) were utilized

New Insights into Female Humpback Whale (Megaptera novaeangliae) Reproductive Endocrinology Revealed by Steroid Hormone Profile Analysis

February 19, 2020
Author(s)
Greta Dalle Luche, Ashley Boggs, John Kucklick, Jasmin Gross, Darryl Hawker, Susan Bengston Nash
The blubber steroid hormone profiles of 52 female humpback whales migrating along the east coast of Australia were investigated for possible seasonal endocrinological changes associated with reproduction. Individuals were randomly sampled in southeast

Blubber steroid hormone profiles as indicators of physiological state in free-ranging common bottlenose dolphins (Tursiops truncatus)

December 31, 2019
Author(s)
Thomas M. Galligan, Ashley Boggs, Brian C. Balmer, Teresa Rowles, Cynthia Smith, Forrest Townsend, Randall Wells, Nicholas Kellar, Eric Zolman, Lori Schwacke
Assessing endocrine health in free-ranging marine mammals can be difficult due to limited access to blood samples, which is the most commonly used sample matrix for endocrine assessment in wildlife. Blubber contains steroid hormones and can be collected

Environmental contaminants in coastal populations: Comparisons with the National Health and Nutrition Examination Survey (NHANES) and resident dolphins

August 21, 2019
Author(s)
Lorraine C. Backer, Birgit Bolton, Jenny A. Litz, Jennifer Hoguet, Stephanie Kieszak, John Kucklick
Background People living in coastal communities are at risk for exposure to environmental hazards, including legacy chemicals. We can use databases such as NHANES to assess whether contaminants in coastal communities are present in higher levels than in
