An expert elicitation to inform coastal management decision-making for mitigating future hazards An expert elicitation to inform coastal management decision-making for mitigating future hazards
A scientific expert elicitation was conducted to address the feasibility of restoring coastal environments in response to future hazards to best meet management objectives. Subject matter experts produced probabilistic estimates of coastal change metrics used to evaluate decision objectives and alternatives informed by a stakeholder advisory group. Changes in salt marsh extents, storm...

Tapwater-contaminant mixtures and risk in a biofuel-facility impacted private-well community Tapwater-contaminant mixtures and risk in a biofuel-facility impacted private-well community
We assessed private-well drinking water (DW) at the point of use (i.e., tapwater, TW) within a rural Nebraska community around a state-closed biofuel facility, which used pesticide-treated corn seed as feedstock for ethanol production. Organic (485), inorganic (34), and microbial (13) analytes were assessed at 15 locations in June 2022, to evaluate the relative contribution of facility...

Rising sea level reduces carbon sequestration and CO2 and N2O fluxes while promoting CH4 flux from mangroves Rising sea level reduces carbon sequestration and CO2 and N2O fluxes while promoting CH4 flux from mangroves
Sea-level rise (SLR) may reduce mangrove carbon sequestration by increasing greenhouse gas (GHG) emissions—a key factor in forecasting the trajectory of blue carbon reserves. Nonetheless, predictions of future GHG fluxes under SLR remain uncertain. Unlike prior studies limited to controlled or single-site settings, we deploy cross-latitude “marsh-organ” designs in China to access GHG...

Validation of gridded precipitation datasets for flood-typing in select conterminous U.S. basins Validation of gridded precipitation datasets for flood-typing in select conterminous U.S. basins
Gridded precipitation datasets are required for flood-typing historical annual peak streamflow events in basins across the Conterminous United States. Selected gridded precipitation datasets were validated over the period 1981–2013 through comparisons with gage data from the NOAA Global Historical Climatology Network daily (GHCNd). The ability of each gridded dataset to capture the...

Quantifying the relative importance of survival threats to a long-lived reptile using expert elicitation Quantifying the relative importance of survival threats to a long-lived reptile using expert elicitation
Long-term survival of a conservation-reliant species requires understanding the impact of threats on population growth rate and the management actions that can help mitigate these threats. We used a threat assessment with expert-elicited estimates to determine the relative effect of each stage-specific threat on the population growth rate of the wood turtle Glyptemys insculpta. In...

Linking stream-reach nitrogen loads and groundwater “reachsheds” to inform wastewater-nitrogen management actions, Cape Cod, Massachusetts Linking stream-reach nitrogen loads and groundwater “reachsheds” to inform wastewater-nitrogen management actions, Cape Cod, Massachusetts
Study RegionCape Cod, Massachusetts, U.S.A.Study FocusAnthropogenic nitrogen (N) is a key factor in degrading groundwater and surface-water quality, particularly in coastal New England where onsite wastewater systems are prevalent. This study evaluated whether direct N-load measurements in streams on Cape Cod, Massachusetts, coupled with flow-path information from groundwater-flow models...

Amitriptyline and nortriptyline induce ocular toxicity in early life stage zebrafish (Danio rerio) Amitriptyline and nortriptyline induce ocular toxicity in early life stage zebrafish (Danio rerio)
The global use of antidepressants has steadily increased, raising concern to aquatic ecosystems due to the incomplete removal during wastewater treatment. Tricyclic antidepressants (TCAs) act on the neuronal system by inhibiting the reuptake of serotonin and norepinephrine. However, despite visual function being heavily dependent on the neuronal system, a knowledge gap remains regarding...

Persistence of a declining anuran species across its distribution Persistence of a declining anuran species across its distribution
Information on a species’ population dynamics, such as changes in abundance and distribution, can be used to identify declining populations and initiate conservation efforts and protections. For the Ornate Chorus Frog (Pseudacris ornata), anecdotal observations of local extirpation and population declines have been noted, but trends in its range-wide population status are generally...

Methods for estimating selected low-flow statistics at gaged and ungaged stream sites in Massachusetts Methods for estimating selected low-flow statistics at gaged and ungaged stream sites in Massachusetts
The U.S. Geological Survey, in cooperation with the Massachusetts Department of Conservation and Recreation, Office of Water Resources, computed selected at-site streamflow statistics at U.S. Geological Survey streamgages in and near Massachusetts and developed regional regression equations for estimating selected streamflows at ungaged stream sites in Massachusetts. Two sets of regional...

Effects of dietary selenium on the amphipod Hyalella azteca and the midge Chironomus dilutus Effects of dietary selenium on the amphipod Hyalella azteca and the midge Chironomus dilutus
Chronic selenium (Se) water quality criteria are based primarily on dietary organoselenium exposure and subsequent reproductive effects in fish. Available chronic Se toxicity data suggests that invertebrates are less sensitive than fish, but chronic invertebrate studies are limited. We evaluated yeast-based diets for chronic toxicity studies with Hyalella azteca and Chironomus dilutus...

Reduced Atlantic reef growth past 2 °C warming amplifies sea-level impacts Reduced Atlantic reef growth past 2 °C warming amplifies sea-level impacts
Coral reefs form complex physical structures that can help to mitigate coastal flooding risk1,2. This function will be reduced by sea-level rise (SLR) and impaired reef growth caused by climate change and local anthropogenic stressors3. Water depths above reef surfaces are projected to increase as a result, but the magnitudes and timescales of this increase are poorly constrained, which...

Ecophysiology of two mesophotic octocorals intended for restoration: Effects of light and temperature Ecophysiology of two mesophotic octocorals intended for restoration: Effects of light and temperature
Light and temperature are driving forces that shape the evolution and physiology of mesophotic organisms. On the Mississippi-Alabama continental shelf, octocorals dominate the mesophotic seascape and provide habitat for many fish and invertebrate species. Gaps in knowledge regarding the fundamental physiological responses of these species to light and temperature are of particular...
