Methanogenic archaea in subsurface coal seams are biogeographically distinct: An analysis of metagenomically-derived mcrA sequences

The production of methane as an end-product of organic matter degradation in the absence of other terminal electron acceptors is common, and has often been studied in environments such as animal guts, soils, and wetlands due to its potency as a greenhouse gas. To date however, the study of the biogeographic distribution of methanogens across coal seam environments has been minimal. Here, we show t

Ecological consequences of neonicotinoid mixtures in streams

Neonicotinoid mixtures are common in streams worldwide, but corresponding ecological responses are poorly understood. We combined experimental and observational studies to narrow this knowledge gap. The mesocosm experiment determined that concentrations of the neonicotinoids imidacloprid and clothianidin (range of exposures, 0 to 11.9 μg/liter) above the hazard concentration for 5% of species (0.0

Lack of evidence for indirect effects from stonefly predators on primary production under future climate warming scenarios

Consumptive and non-consumptive interactions of predators and prey can have strong direct and indirect effects on primary producers, such as stream algae. Increasing water temperatures may alter these interactions and thus influence productivity in streams. For each of 3 temperature treatments (‘ambient’, +2°C and +4°C), we measured the amount of algal biomass removed by grazing mayflies from 91 m

History of Water-Quality Sampling the the Lake Koocanusa Basin

Since 1984, Canadian agencies have collected samples to measure selenium concentrations in the Elk River measured at the monitoring station (site BC08NK0003) (British Columbia Ministry of Forests Lands Natural Resource Operations and Rural Development, 2022) which is 2.2 miles above its discharge into Lake Koocanusa. Detections of selenium from this site have ranged from below detection to greater...

Snake River Basin Streamflow and Water Temperature

The USGS WY-MT Water Science Center operates streamgages in the Snake River Basin in Wyoming that report streamflow in the mainstem of the Snake River and tributary streams. During the spring of 2022, in cooperation with the Teton Conservation District, thermistors were installed at six sites in the basin to record and report water temperature data. There are currently 12 sites in the basin that...
