Atmospheric deposition of nitrogen and sulfur, after land use change, is one of the most impactful stressors to terrestrial biodiversity. Deposition effects on ecosystems are pervasive, impacting species distributions and disrupting natural communities and associated ecosystem se...

Subsurface contamination can migrate upward into overlying buildings, exposing the buildings&rsquo; inhabitants to contaminants that can cause detrimental health effects. This phenomenon is known as vapor intrusion (VI). When evaluating a building for VI, one must understand that...

A literature-based quantitative microbial risk assessment (QMRA) was performed for the fit-for-purpose use of roof-collected rainwater in high-pressure vehicle washing. Our exposure assessment combined estimates of enteric pathogens in roof runoff (available for&nbsp;Salmonella,&...

The Coastal Generalized Ecosystem Model (CGEM) is a biogeochemical model developed to study regulating processes of water-column optical properties, water-column and benthic carbon, oxygen, and nutrient cycles, and phytoplankton and zooplankton dynamics. CGEM offers numerous form...

Efforts to improve water quality in urbanized embayments may be complicated by changes that predate contemporary ecological monitoring efforts. Such is the case in Wickford Harbor, Rhode Island, one of the oldest continuous settlements in the northeastern USA, that is exhibiting ...

Extensive cyanobacteria-dominated mats were observed during late summer of 2021 within coastal urban stormwater retention pond networks in northwest Florida. Common in residential communities across the region, such ponds may be routinely visited by humans, domestic and wild anim...

Wetland habitats provide critical ecosystem services to the surrounding landscape, including nutrient and pollutant retention, flood mitigation, and carbon storage. Wetland connectivity to water bodies and related ecosystems is critical in habitat sustainability, but there are li...

A portion of Alaska&rsquo;s Fairbanks North Star Borough was designated as nonattainment for the 2006 24 h fine particulate matter 2.5 &micro;m or less in diameter (PM2.5) National Ambient Air Quality Standards (NAAQS) in 2009. PM2.5 NAAQS exceedances in Fairbanks mainly occur du...

Coastal wetlands, including seagrass meadows, marshes, mangroves, and temperate tidal swamps, can efficiently sequester and store large quantities of sediment organic carbon (SOC). However, SOC stocks may vary by ecosystem type and along environmental or climate gradients at diff...

Coral reefs off the coast of West Maui in Hawai'i are frequently subjected to highly turbid water, caused in part by terrigenous sediment inputs from stream gulches after rain events. Sediment has numerous deleterious consequences on scleractinian corals, including impacts on gro...

Extreme natural hazard events are increasing across the globe, compelling increased climate research on resiliency. Research concerning issues as integrative as climate change and natural hazard resiliency often requires complex methodologies to account for cumulative influences....

This study enhances hydrological modeling in ungauged watersheds by employing physical similarity and machine learning-based clustering for regionalizing the Soil and Water Assessment Tool (SWAT) model parameters at the HUC12 (hydrological unit code) watershed scale within a HUC0...

Anthropogenic climate change and changes to land use and land management practices can have significant impacts on streamflow and sediment transport. In this study, we investigated long-term precipitation, streamflow, and suspended sediment load patterns within the Hangman Creek ...

Edge-of-field management practices that reduce nutrient pollution from tile drainage while contributing habitat and other ecosystem services are needed to enhance US Corn Belt agricultural systems. In this review, we identified edge-of-field and catchment scale agricultural conse...

In this study, we demonstrate a physically based semi-Lagrangian water temperature model known as the River Basin Model (RBM) coupled with the Variable Infiltration Capacity (VIC) hydrological model and Weather Research &amp; Forecasting Model in the Mississippi River Basin (MRB)...

The protection of headwater streams faces increasing challenges, exemplified by limited global recognition of headwater contributions to watershed resiliency and a recent US Supreme Court decision limiting federal safeguards. Despite accounting for ~77% of global river networks, ...

We used EPA&rsquo;s ecohydrology model, Visualizing Ecosystem Land Management Assessments (VELMA), to 1) conduct a performance-tested synthesis of long-term Konza Prairie Biological Station (KPBS) experimental data capable of describing the interactive effects of climate, fire, g...

Estuaries have been adversely impacted by increased nutrient loads. Eutrophication impacts from these loads include excess algal blooms and low oxygen conditions. In this study, we leveraged data from 28 monitoring programs in the northeastern US to explore the relationships betw...

To increase the resilience of salt marshes subject to sea-level rise impacts, managers can focus on interventions within current marsh footprints or in adjacent uplands to facilitate landward marsh migration. The latter approach may be more appropriate when degradation is severe ...

Conductivity is an important indicator of the health of aquatic ecosystems. We model large amounts of lake conductivity data collected as part of the United States Environmental Protection Agency's National Lakes Assessment using spatial indexing, a flexible and efficient approac...

Now more than ever, complex socio-ecological challenges require timely and integrated responses from scientists and policymakers. Air quality is one such challenge. Under the Clean Air Act, the U.S. Environmental Protection Agency establishes ambient air quality standards to prot...

Amphibians worldwide are threatened by habitat loss, some of which is driven by a changing climate, as well as exposure to pesticides, among other causes. The timing and duration of the larval development phase vary between species, thereby influencing the relative impacts of sto...

Salt marshes, critical habitats offering many ecosystem services, are threatened by development, accelerated&nbsp;sea level rise&nbsp;(SLR) and other&nbsp;anthropogenic stressors&nbsp;that are projected to worsen. As seas rise, some salt marshes can migrate inland if there is adj...

Reliable estimates of low flow and flood discharge at ungaged locations are required for evaluating stream flow alteration, designing culverts and stream crossings, and for interpreting regional surveys of habitat and biotic condition.&nbsp; The majority of locations where discha...

Global declines in mangroves, seagrasses, and corals threaten the provisioning of ecosystem services to coastal communities. However, potential feedbacks between these ecosystems are poorly understood owing to a lack of studies exploring functional links between these frequently ...
