A novel approach to assessing natural resource injury with Bayesian networks A novel approach to assessing natural resource injury with Bayesian networks
Quantifying the effects of environmental stressors on natural resources is problematic because of complex interactions among environmental factors that influence endpoints of interest. This complexity, coupled with data limitations, propagates uncertainty that can make it difficult to causally associate specific environmental stressors with injury endpoints. The Natural Resource Damage...

Long-term changes in concentrations and yield of riverine dissolved silicon from the poles to the tropics Long-term changes in concentrations and yield of riverine dissolved silicon from the poles to the tropics
Riverine exports of silicon (Si) influence global carbon cycling through the growth of marine diatoms, which account for ∼25% of global primary production. Climate change will likely alter river Si exports in biome-specific ways due to interacting shifts in chemical weathering rates, hydrologic connectivity, and metabolic processes in aquatic and terrestrial systems. Nonetheless, factors...

High-frequency variability of carbon dioxide fluxes in tidal water over a temperate salt marsh High-frequency variability of carbon dioxide fluxes in tidal water over a temperate salt marsh
Existing analyses of salt marsh carbon budgets rarely quantify carbon loss as CO2 through the air–water interface in inundated marshes. This study estimates the variability of partial pressure of CO2 (pCO2) and air–water CO2 fluxes over summer and fall of 2014 and 2015 using high-frequency measurements of tidal water pCO2 in a salt marsh of the U.S. northeast region. Monthly mean CO2...

Bathymetric contour maps, surface area and capacity tables, and bathymetric change maps for selected water-supply lakes in northeastern Missouri, 2021 Bathymetric contour maps, surface area and capacity tables, and bathymetric change maps for selected water-supply lakes in northeastern Missouri, 2021
Bathymetric data were collected at 12 water-supply lakes in northeastern Missouri by the U.S. Geological Survey (USGS) in cooperation with the Missouri Department of Natural Resources (MoDNR) and various local agencies, as part of a multiyear effort to establish or update the surface area and capacity tables for the surveyed lakes. The lakes were surveyed in March through May 2021. Ten...

Mapping methane reduction potential of tidal wetland restoration in the United States Mapping methane reduction potential of tidal wetland restoration in the United States
Coastal wetlands can emit excess methane in cases where they are impounded and artificially freshened by structures that impede tidal exchange. We provide a new assessment of coastal methane reduction opportunities for the contiguous United States by combining multiple publicly available map layers, reassessing greenhouse gas emissions datasets, and applying scenarios informed by...

Long-term trends in Arctic riverine chemistry signal multi-faceted northern change Long-term trends in Arctic riverine chemistry signal multi-faceted northern change
Rivers integrate processes occurring throughout their watersheds and are therefore sentinels of change across broad spatial scales. River chemistry also regulates ecosystem function across Earth’s land–ocean continuum, exerting control from the micro- (for example, local food web) to the macro- (for example, global carbon cycle) scale. In the rapidly warming Arctic, a wide range of...

Predation of invasive silver carp by native largemouth bass is size-selective in the Illinois River Predation of invasive silver carp by native largemouth bass is size-selective in the Illinois River
Silver carp (Hypophthalmichthys molitrix) are a nonnative, planktivorous, and highly invasive species of cyprinid located throughout the Mississippi River Basin. Although they co-occur with largemouth bass (Micropterus nigricans), an abundant native predatory fish, their predator–prey relationship is poorly understood. This potential relationship warrants investigation as largemouth bass...

Identifying demographic and environmental drivers of population dynamics and viability in an endangered top predator using an integrated model Identifying demographic and environmental drivers of population dynamics and viability in an endangered top predator using an integrated model
Knowledge about the demographic and environmental factors underlying population dynamics is fundamental to designing effective conservation measures to recover depleted wildlife populations. However, sparse monitoring data or persistent knowledge gaps about threats make it difficult to identify the drivers of population dynamics. In situations where small, declining, or depleted...

Scale-dependent tradeoffs between habitat and time in explaining Alligator Gar (Atractosteus spatula) movement Scale-dependent tradeoffs between habitat and time in explaining Alligator Gar (Atractosteus spatula) movement
Ecological theory predicts that movement by riverine fishes at the population level is characterized by both stationary and mobile individuals together creating a leptokurtic distribution of movement distances. However, studies testing this theory typically ignore spatial heterogeneity in riverscapes, and the theory has not been tested using Alligator Gar (Atractosteus spatula), a...

Independent age estimates resolve the controversy of ancient human footprints at White Sands Independent age estimates resolve the controversy of ancient human footprints at White Sands
Human footprints at White Sands National Park, New Mexico, USA, reportedly date to between ~23,000 and 21,000 years ago according to radiocarbon dating of seeds from the aquatic plant Ruppia cirrhosa. These ages remain controversial because of potential old carbon reservoir effects that could compromise their accuracy. We present new calibrated 14C ages of terrestrial pollen collected...

Flood damage costs beyond buildings—A Lake Champlain case study Flood damage costs beyond buildings—A Lake Champlain case study
Introduction Floods account for more than 75 percent of Federal disaster declarations and lead other natural disasters in economic costs. Early-warning systems have lowered flood-related fatalities, but costs continue to rise as flood-prone areas continue to be urbanized (U.S. Geological Survey, 2006). A Lake Champlain case study shows that at moderate flood heights, the economic costs...

Wide-area debris field and seabed characterization of a deep ocean dump site surveyed by autonomous underwater vehicles Wide-area debris field and seabed characterization of a deep ocean dump site surveyed by autonomous underwater vehicles
Disposal of industrial and hazardous waste in the deep ocean was a pervasive global practice near coastlines in the 20th century. Uncertainty in the quantity, location, and contents of dumped materials at historical disposal sites underscores ongoing risks to marine ecosystems and human health. This study presents analysis of a 150-km2 wide-area sidescan sonar survey conducted in March...
