Agricultural Pesticides Could Be Impacting the Natural Beauty at Sequoia National Park Through Atmospheric Deposition

High up in the remote alpine and subalpine lakes of Sequoia and Kings Canyon National Park (SEKI), the crystal-clear lakes appear to be greening with an overpopulation of periphyton. Periphyton is a mixture of various water microbes such as algae, cyanobacteria, and others. Scientists at the USGS Columbia Environmental Research Center and the University of Missouri are working with National Park...

A National Assessment of Pesticide, PFAS, Microplastic, and Antibiotic Resistance Gene Exposures in White-Tailed Deer

Research has documented exposures and consequential environmental health effects of pesticides, PFAS, microplastics, and antibiotic resistance genes in environmental biota. Little is known, however, regarding such effects in white-tailed deer ( Odocoileus virginianus ).

New Technology to Support Culturing of Freshwater Mussels for Research and Restoration

Freshwater mussels are one of the most critically imperiled groups of organisms worldwide. Encouraging mussel reproduction in a controlled setting has become an area of interest due to their widespread population declines and regional extinctions (Williams et al., 1993; Lydeard et al., 2004; Strayer et al., 2004; Haag 2012; Lopes-Lima et al., 2017). With constantly evolving techniques, rearing...

Use and Evaluation of Stimuli for Herding Bigheaded Carps to Increase their Capture Efficiency

Mass removal of the invasive silver carp Hypophthalmichthys molitrix and bighead carp Hypophthalmichthys nobilis (collectively referred to as bigheaded carp) is a primary management action in the United States to contain population growth and reduce upstream dispersal. Efficient capture and removal techniques are required to achieve this goal, and the USGS is working to develop and evaluate such...

Using Effects-Directed Analysis to test for Endocrine-Active Chemicals

Effects-directed analysis (EDA) reverse-engineers environmental toxicity testing by measuring effects on cells first, and identifying the particular chemicals later. In this publication, we reviewed published information on EDA methods to improve future methods.
