Detections of marine fauna using environmental DNA metabarcoding of seawater samples from the northern Gulf of America
We sampled seawater from nine mesophotic reef sites in the Pinnacles Trend and DeSoto Rim areas in the northern Gulf of America in October 2022 to complement and inform restoration investments for coral communities. Four primer sets were used to amplify environmental DNA (eDNA) from seawater, targeting metazoans, eukaryotic plankton and protists, corals, and fishes. Across all markers...
Environmental DNA detections from deep seafloor habitats in the California Current Large Marine Ecosystem
Environmental DNA (eDNA) metabarcoding may have utility in biodiversity surveys of marine environments, particularly for small, rare, or cryptic taxa that are more difficult to study using traditional methods (e.g., trawling and visual surveys). For this study, we used an eDNA metabarcoding approach to characterize biodiversity in the above-seafloor water column across three West Coast...
Conservation Genetics and Genomics of the Narrowly Endemic Island Marble Butterfly: Assessing Population Structure, Facilitating Supportive Breeding, and Identifying Adaptive Potential
The purpose of this study was to collect and analyze non-invasive DNA specimens from the endangered island marble butterfly (Euchloe ausonides insulanus) to assess population structure, identify adaptive potential, facilitate captive propagation, and support translocation planning. We used DNA extracted from meconium, exuviae, and natural mortalities to generate and test thirteen new...
SARS-CoV-2 Data from National Wastewater Surveillance System Surge Capacity Sampling, September 2021
Wastewater-based epidemiology (WBE) is used to determine the consumption of, or exposure to, chemicals or pathogens in human populations, and is conducted by collecting representative samples of untreated wastewater (influent) to quantify pathogens shed in the population served by the sampled wastewater system. The Centers for Disease Control and Prevention (CDC) and the US Department of...
Summary of Stranded Southern Sea Otters, 1985-2018 (ver. 3.0, June 2021)
The southern sea otter (Enhydra lutris nereis), also known as California sea otter, was listed as threatened in 1977 under the Endangered Species Act. Since 1985, stranded otters from throughout their California coastal range have been collected and analyzed to inform resource management on recovery and conservation of the species. This data set is a complete 31 year compilation. Future...
Comprehensive genetic analyses reveal evolutionary distinction of a mouse (Zapus hudsonius preblei) proposed for delisting from the US Endangered Species Act
Zapus hudsonius preblei, listed as threatened under the US Endangered Species Act (ESA), is one of 12 recognized subspecies of meadow jumping mice found in North America. Recent morphometric and phylogenetic comparisons among Z. h. preblei and neighbouring conspecifics questioned the taxonomic status of selected subspecies, resulting in a proposal to delist the Z. h. preblei from the ESA...
