Evidence is lacking for what constitutes effective climate change adaptation to successfully conserve and steward ecosystems. Yet we urgently need this information to develop robust adaptation strategies to keep pace with unprecedented change, given our limited resources to do so...

Wetlands are known to provide a myriad of vital ecosystem functions and services, which may be under threat from a changing climate. However, climate change effects may not be homogenous across ecosystem functions, wetland types, or ecoregions. Therefore, it may not be appropriat...

The lateral transport of dissolved organic carbon (DOC) is crucial in tidal marsh carbon budgets, but estimating DOC remains a challenge due to the dynamic nature of terrestrial-aquatic interfaces and limitations of in situ observations. This study used a linear model t...

Clouds are important physicochemical processors of atmospheric pollutants. Major contributors to secondary sulfate, clouds also provide media for the production and processing of secondary organic aerosol (SOA). Sulfate and organic compounds often dominate particulate mass, and t...

Continuous monitoring data required for performing environmental model simulations using gridded land surface models (LSMs) are often difficult to obtain and manage, making the modeling process challenging and prone to error. In response, this study focuses on automated retrieval...

Using the US Geological Survey groundwater model, we compared spatial distribution, flow exchange, and storage of groundwater between cropland and forestland in the Upper Yazoo River Watershed, Mississippi, from 1900 to 2014. Under normal climate, average groundwater head decline...

Understanding wetland carbon stores and dynamics are critical to managing global carbon flux. Non-floodplain wetlands (NFWs) are hydrologically dynamic and globally prevalent inland wetlands distal to fluvial flowpaths, lacustrine-fringing areas, and geomorphic floodplains; >5...

Excessive nutrient loading to surface waters endangers drinking water supplies, recreation, aquatic life, and many other water quality end points. Unfortunately, concentrations of phosphorus (P) and nitrogen (N) remain high in many U.S. waterbodies and may be increasing in remote...

Alongside global climate change, many freshwater ecosystems are experiencing substantial shifts in the concentrations and compositions of salt ions coming from both land and sea.   We synthesize a risk framework for anticipating how climate change and increasing salt po...

Climate change is accelerating the release of dissolved organic matter (DOM) to inland and coastal waters through increases in precipitation, thawing of permafrost, and changes in vegetation. Our modeling approach suggests that the selective absorption of ultraviolet radiation (U...

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’ 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 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’s Fairbanks North Star Borough was designated as nonattainment for the 2006 24 h fine particulate matter 2.5 µm 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 & Forecasting Model in the Mississippi River Basin (MRB)...
