Abstract Because of their abundance and high emissions rates, small reservoirs (< 0.01 km 2 ) can be important emitters the greenhouse gases carbon dioxide methane. However, estimates from have lagged those larger ones, efforts to characterize reservoir largely overlooked variations in pathways, times, locations. We intensively sampled four Georgia, USA, during summer quantify contribution spatiotemporal variability different pathways (CO CH 4 diffusion, ebullition). used these data...
Selenium is highly elevated in Appalachian streams and stream organisms that receive alkaline mine drainage from mountaintop removal coal mining compared to unimpacted the region. Adult aquatic insects can be important vectors of waterborne contaminants riparian food webs, yet pathways Se transport exposure are poorly characterized. We investigated concentrations determine whether extent increased uptake biofilms if these were effective biovectors spiders. Biofilm concentration (p = 0.006)...
The Clean Water Act (CWA) of 1972 regulates water quality in U.S. inland waters under a system cooperative federalism which states are delegated implementation and enforcement authority CWA provisions by the Environmental Protection Agency. We leveraged heterogeneity state to evaluate efficacy its nonpoint source reducing nutrient pollution, leading cause impairment waters. used national survey data estimate changes concentrations over decade evaluated effect state-level policy...
Civil infrastructure will be essential to face the interlinked existential threats of climate change and rising resource demands while ensuring a livable Anthropocene for all. However, conventional planning largely neglects contributions maintenance Earth’s ecological life support systems, which provide irreplaceable services supporting human well-being. The stability performance these depend on biodiversity, but practices, narrowly focused controlling natural capital, have inadvertently...
ABSTRACT Proactive and transparent decision‐making about the long‐term management of dams, including rehabilitation, retrofit, removal, is critical for successfully managing this aging infrastructure presents an opportunity to weigh many services disservices dams provide. Existing tools support dam removal decisions often constrain decision processes by considering only a limited set user objectives. We identified 18 objectives in literature found that most 41 decision‐support we evaluated...
Mountaintop removal coal mining is the predominant form of surface in Appalachian Region United States and leads to elevated levels chemical constituents streams draining mined watersheds.
