Acetylene (C2H2) is a molecule rarely found in nature, with few known natural sources, but acetylenotrophic microorganisms can use acetylene as their primary carbon and energy source. As of 2018 there were 15 known strains of aerobic and anaerobic acetylenotrophs, however we hypothesized that there may be yet unrecognized diversity of acetylenotrophs in nature. In this study, we expanded this diversity by isolating an aerobic acetylenotroph, Bradyrhizobium sp. strain I71, from trichloroethene (TCE)-contaminated soils undergoing bioremediation. TCE-contaminated soils from the NASA Ames Research Center in California were used to establish soil microcosms with acetylene as the primary carbon substrate and acetylene...

Water, sediment, anuran food (leaf litter and detritus) and whole body larval amphibian composites were analyzed for over 100 current-use pesticides from 24 wetlands representing land-use gradients in the New Jersey Pinelands, USA during 2014-2016. Emerging amphibian pathogens, Ranavirus and Batrachochytrium dendrobatidis (Bd) were also assessed in individual larvae at the 24 wetlands. Tables in this data release contain the results from these analyses, with quality assurance summaries, along with site information, including land-use classifications.

Twelve chemical elements have intervals for their standard atomic weights, namely hydrogen, lithium, boron, carbon, nitrogen, oxygen, magnesium, silicon, sulfur, chlorine, bromine and thallium. Isotopic abundances, isotope-delta values, and atomic weights for each of the lower and upper bounds of materials and compounds of these 12 elements are tabulated. Version 1.1 is the most current version.
