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

Hydrologic Monitoring on the Fort Peck Reservation, Montana

The Fort Peck Assiniboine & Sioux Tribes seek an increased scientific understanding of the water resources within the Fort Peck Reservation of northeastern Montana. Hydrologic information is needed to make informed water management decisions, including the monitoring of instream flows established in the Fort Peck Indian Reservation Water Rights Compact with the State of Montana. The Fort Peck...

Using Satellite Imagery to Estimate Consumptive Water Use from Irrigated Lands in the Milk River Basin, United States and Canada

The U.S. Geological Survey, with the support of the International Joint Commission, and in cooperation with Alberta Environment and Parks, Blackfeet Nation, Environment and Climate Change Canada, and Montana Department of Natural Resources and Conservation, is leading a project that should improve information available to apportion water between Canada and the United States in the St. Mary and...
