Certain species within the genus Pseudo-nitzschia are able to produce the neurotoxin domoic acid (DA), which can cause illness in humans, mass-mortality of marine animals, and closure of commercial and recreational shellfisheries during toxic events. Understanding and forecasting...

The successful implementation and sustainability of many marsh restoration efforts, including coastal adaptation to buffer inundation and mitigate sea level rise, often hinges upon support from surrounding human communities. Yet, stakeholder engagement in these projects remains r...

Water resources are critically important but also pose risks of exposure to toxic and pathogenic microbes. Increasingly a concern are toxic cyanobacteria, which have been linked to the death and disease of humans, domesticated animals, and wildlife in freshwater systems worldwide...

Seagrass&nbsp;meadows&nbsp;are degraded globally and continue to decline in areal extent due to human pressures and climate change. This study used the bio-optical model&nbsp;GrassLight&nbsp;to explore the impact of climate change and&nbsp;anthropogenic stressors&nbsp;on seagrass...

Global climate models (GCMs) and Earth system models (ESMs) provide many climate services with environmental relevance. The High Resolution Model Intercomparison Project (HighResMIP) of the&nbsp;Coupled Model Intercomparison Project&nbsp;Phase 6 (CMIP6) provides model runs of GCM...

Earth system models (ESMs) serve as a unique research infrastructure for quality climate services, yet their application for environmental management at regional scale has not yet been fully explored. The unprecedented resolution and model fidelity of the Coupled Model Intercompa...

Amphibian populations are threatened by multiple potential stressors, including environmental variability and climate-related changes in habitat availability.&nbsp; Ecological risk assessment of amphibians ideally should encompass the appropriate spatial and temporal scale to ade...

Heightened recognition of impacts to coastal salt marshes from sea-level rise has led to expanding interest in using thin-layer sediment placement (TLP) as an adaptation tool to enhance future marsh resilience. Building on successes and lessons learned from the Gulf and southeast...

As a symptom of accelerated sea level rise and historic impacts to tidal hydrology from agricultural and mosquito control activities, coastal marshes in the Northeastern U.S. are experiencing conversion to open water through edge loss, widening and headward erosion of tidal chann...

Seagrasses are globally recognized for their contribution to blue carbon sequestration. However, accurate quantification of their carbon storage capacity remains uncertain due, in part, to an incomplete inventory of global seagrass extent and assessment of its temporal variabilit...

Ecosystems in the Anthropocene face pressures from multiple, interacting forms of environmental change. These pressures, resulting from land use change, altered hydrologic regimes, and climate change, will likely change the synchrony of ecosystem processes as distinct components ...

Wildland fires are a major source of gases and aerosols, and the production, dispersion, and transformation of fire emissions have significant ambient air quality impacts and climate interactions. The increase in the wildfire area burned and severity across the US and Canada in r...

Ballast water&nbsp;is a leading pathway for the global introduction of aquatic nonindigenous species. Most international ships are expected to install ballast water management systems (BWMS) by 2024 to treat ballast water before release. This study examines if ballast water disch...

We used a dynamic soil-vegetation model (ForSAFE-Veg) to simulate responses to future scenarios of atmospheric deposition and climate change across 23 Northeastern hardwood stands. Specifically, we simulated soil percent base saturation, acid neutralizing capacity (ANC), nitrate ...

This study estimates an ensemble of future changes in coastal wetland areas considering both sea level rise, future greenhouse gas emissions, and accretion rate uncertainty, using outputs from the National Ocean and Atmospheric (NOAA) marsh migration model.

Lake hydrology is integral to lake ecological condition, but human-related water needs and changing climate conditions may alter hydrology beyond natural ranges. Separating natural and human effects can support lake management and assessment and requires a clear conceptual unders...

Ocean acidification and eutrophication have direct, positive effects on the growth of many marine macroalgae, potentially resulting in macroalgal blooms and shifts in ecosystem structure and function. Enhanced growth of macroalgae, however, may be controlled by the presence of gr...

Forest understory plant communities in the United States are diverse and often sensitive to changes in climate and atmospheric inputs of nitrogen (N) caused by air pollution. Recently, understory vegetation response functions (expressed as Probability of Occurrence of Plant Speci...

We examine how the frequency of cyanobacterial&nbsp;harmful algal blooms&nbsp;(cyanoHABs) generates economic costs through the mechanism of residential property values. We assemble nearly two decades worth of nationwide data on property sales near US inland lakes along as well as...

There is increasing evidence from across the globe that climate change results in changes in the frequency, location, and impact of natural hazards. Much of this evidence is conceptual, inferential, or simply assumed. To provide objective support to confirm these hypotheses, we c...

Knowing where and when rivers flow is paramount to managing freshwater ecosystems. Yet stream gauging stations are distributed sparsely across rivers globally and may not capture the diversity of fluvial network properties and anthropogenic influences. Here we evaluate the placem...

Intermittent rivers and ephemeral streams (IRES) are watercourses that cease flow at some point in time and space. Arguably Earth's most widespread type of flowing water, IRES are expanding where Anthropocenic climates grow drier and human demands for water escalate. However, IR...

Social network analysis (SNA) tools and concepts are essential for addressing many environmental management and sustainability issues. One method to gather SNA data is to scrape them from environmental organizations&rsquo; websites. Web-based research can provide important opport...

Previous studies indicate that cyanobacterial harmful algal bloom (cyanoHAB) frequency, extent, and magnitude have increased globally over the past few decades. However, little quantitative capability is available to assess these metrics of cyanoHABs across broad geographic scale...

Eutrophication&nbsp;and excessive algal growth pose a threat on aquatic organisms and the health of the public, environment, and the economy. Understanding what drives excessive algal growth can inform&nbsp;mitigation measures&nbsp;and aid in advance planning to minimize impacts....
