The Montreal Protocol and the fate of environmental plastic debris
(JOURNAL) [Published : May 01, 2023]
Microplastics (MPs) are an emerging class of pollutants in air, soil, and, especially, in all aquatic environments.  Secondary MPs are generated in the environment during fragmentation of especially photo-oxidized plastic litter. Photo-oxidation is mediated primarily by sola...
Development of Community-Level Capacity of Resilience to Natural Hazards for Environmental- and Social-Justice-Challenged Communities: 1. Approach, Concepts, and Assessment of Existing Information
(JOURNAL) [Published : Jan 23, 2024]
Impoverished and under-served communities are often exposed to the worst environmental and climate hazards. Identifying these communities and building their resilience capacity to withstand such hazards is a vital justice aspect of environmental management. Building community res...
Geographic variation in projected US forest aboveground carbon responses to climate change and atmospheric deposition
(JOURNAL) [Published : Feb 20, 2024]

Impacts of nitrogen pollution on terrestrial ecosystems in the United States
(JOURNAL) [Published : Sep 01, 2015]
Nitrogen (N) has historically been the nutrient that most often limits plant growth in the United States. However, human activity since the Industrial Revolution has resulted in increased emission and hence deposition of N.1 Initial increases in N deposition can act as a fertiliz...

(JOURNAL) [Published : Mar 05, 2024]
Permafrost soils store ∼50% of terrestrial C, with Yedoma permafrost containing ∼25% of the total C. Permafrost is undergoing degradation due to thawing, with potentially hazardous effects on landscape stability and water resources. Complicating ongoing efforts to project...
Population genetic patterns across the native and invasive range of a widely distributed seagrass: Phylogeographic structure, invasive history and conservation implications
(JOURNAL) [Published : Mar 01, 2024]
Understanding the spatial and temporal distribution patterns of genetic diversity and the underlying phylogeographic processes is a fundamental goal of conservation biogeography. The seagrass Zostera japonica is a widely threatened endemic seagrass species in the Northwestern Pac...
Indicators of the effects of climate change on freshwater ecosystems
(JOURNAL) [Published : Mar 01, 2023]
Freshwater ecosystems, including lakes, streams, and wetlands, are responsive to climate change and other natural and anthropogenic stresses. These ecosystems are generally hydrologically connected with one another and with the landscapes around them, integrating changes that occ...
Recent Advancement in Mangrove Forests Mapping and Monitoring of the World Using Earth Observation Satellite Data
(JOURNAL) [Published : Feb 05, 2021]
Mangrove forests are distributed in the tropical and subtropical regions of the world largely con-fined within ± 10 degrees latitude. The forests provide important ecosystem goods and services to nature and society. In recent years, the carbon sequestration potential and p...
Where forest may not return in the western United States
(JOURNAL) [Published : Dec 07, 2022]
Climate-related changes to drought, fire, and insect outbreak regimes have raised concerns that western United States forests, once disturbed, may not return or reattain prior structure and composition.  Many post-fire recruitment studies have documented absence or low densi...
Enhancing Multiple Benefits of Brownfield Cleanups by Applying Ecosystem Services Concepts
(JOURNAL) [Published : Feb 23, 2024]
Brownfields are increasingly called upon to be transformed from potentially contaminated, often vacant properties into community assets that provide multiple benefits. Decision-makers are using recent policy tools to encourage brownfields revitalization that helps to combat the c...
A review of ecosystem services from edge-of-field practices in tile-drained agricultural systems in the United States Corn Belt Region
(JOURNAL) [Published : Dec 15, 2023]
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...
Climate Change Will Impact Surface Water Extents and Dynamics Across the Central United States
(JOURNAL) [Published : Feb 11, 2024]
Climate change is projected to impact river, lake, and wetland hydrology, with global implications for the condition and productivity of aquatic ecosystems. We integrated Sentinel-1 and Sentinel-2 based algorithms to track monthly surface water extent (2017–2021) for 32 sit...
How resilience is framed matters for governance of coastal social-ecological systems
(JOURNAL) [Published : Feb 01, 2024]
  Effective governance of social-ecological systems (SES) is an enduring challenge, especially in coastal environments where accelerating impacts of climate change are increasing pressure on already stressed systems. While resilience is often proposed as a suitable f...
The changing nitrogen landscape of United States streams: Declining deposition and increasing organic nitrogen
(JOURNAL) [Published : Jan 01, 2024]
Air quality regulations decreased nitrogen (N) and sulfur deposition across the conterminous United States (CONUS) during the last several decades. But it is unclear if declining deposition has also altered stream N at large scales. We compared watershed N inputs with N chemistry...
To Burn or Not to Burn: Governance of wildfires in Australia
(JOURNAL) [Published : Jan 01, 2024]
Globally, wildfires are increasing in extent, frequency, and severity. Although global climate change is a major driver and large-scale governance interventions are essential, focusing on governance at smaller scales is of great importance for fostering resilience to wildfires. I...
Identifying untapped legal capacity to promote multi-level and cross-sectoral coordination of natural resource governance
(JOURNAL) [Published : Nov 28, 2023]
Natural resource governance in the face of climate change represents one of the seminal challenges of the Anthropocene. A number of innovative approaches have been developed in, among others, the fields of ecology, governance, and sustainability sciences for managing uncertainty ...
Hazardous and contaminated sites within salt marsh migration corridors in Rhode Island, USA.
(JOURNAL) [Published : Apr 01, 2023]
As salt marshes attempt to migrate upland due to sea level rise, they will encounter many kinds of land development and infrastructure in highly populated, urbanized coastal communities. Hazardous and contaminated sites (HCSs) -- facilities and infrastructure that store...
