Low Impact Development (LID) is an alternative to conventional urban stormwater management practices, which aims at mitigating the impacts of urbanization on water quantity and quality. Plot and local scale studies provide evidence of LID effectiveness; however, little is known a...

The EPA is responsible for ensuring the safety of thousands of chemicals. Quantitative exposure data are available for only a small fraction of registered chemicals. This type of exposure data is needed to thoroughly evaluate chemicals for potential risks to humans, wildlife and ...

While underwater video collection technology continues to improve, advancements in underwater video analysis techniques have lagged. Crowdsourcing image interpretation using the Zooniverse platform has proven successful for many projects, but few projects to date have included vi...

Seagrass is a highly valuable component of coastal ecosystems ecologically and economically, yet reliable mapping of seagrass density is not available due to the high cost of data processing and spatial mapping. This paper presents a deep learning approach for quantification of l...

The spatial distribution of long-term changes in climatic factors and its relation with vegetation cover, human health, hydrology and many other ecosystem processes help to identify the consequences of climatic factors changes. In recent studies, the significant changes of select...

Advances in understanding the optics of shallow water environments, submerged vegetation canopies and seagrass physiology, combined with improved spatial resolution of remote sensing platforms, now enable eelgrass ecosystems to be monitored at a variety of time scales from earth-...

Currently, several studies highlight the importance of ecosystem services, including those related to water resources, such as water supply, irrigation, recreation and power generation. Augmented production and transport of fine sediments resulting from increased human activities...

Modeling exposure and recovery of fish and wildlife populations after stressor mitigation serves as a basis for evaluating population status and remediation success. The Atlantic killifish (Fundulus heteroclitus) is an important and well-studied model organism for understanding ...

Over their lifetime, fish experience damage to their fins from a variety of natural sources (e.g., predators, abrasion). Generally, that damage is repaired through the process of fin regeneration. However, some chemicals have been shown to impair the fin regeneration process. Aqu...

Tidal freshwater ecosystems experience acute seawater intrusion associated with periodic droughts, but are expected to become chronically salinized as sea level rises. Here we report the results from an experimental manipulation in a tidal freshwater Zizaniopsis miliacea marsh on...

It is important to understand molecular effects on plants exposed to compounds released from use of products containing engineered nanomaterials. Here, we present mRNA sequencing data on transcriptome impacts to Douglas-fir following 2 weeks of sublethal exposure to 30:1 diluted ...

Vector-borne diseases are increasing in geographic extent and incidence in the United States and worldwide. Municipalities allocate resources to control arthropod vectors to protect human health using the best available information. The combined impacts of human-mediated ecosyste...

This presentation describes EPA Research for a staff visit for Congressional Rep. Suzanne Bonamici (OR 1st District). It provides an overview of water quality and ecosystem services research by the EPA at the Western Ecology Division. This presentation is given in conjunction wit...

Over recent decades the government has made a wealth of information publicly available as part of the Federal Open Data Policy. The EnviroAtlas provides a wealth of geospatial data and other resources to decision makers, educators, and researchers. EnviroAtlas resources are organ...

New concepts have emerged in theoretical ecology with the intent to quantify complexities in ecological change that are unaccounted for in state-and-transition models and to provide applied ecologists with statistical early warning metrics able to predict and prevent state transi...

Estuarine river watersheds provide valuable ecosystem services to their surrounding communities including drinking water and habitat for fish and wildlife; they also affect estuarine water quality. However, the provisioning of these services can be affected by changes in the qua...

Fire is a vital process for sustained ecosystem functioning, providing habitat vitality and renewal through recolonization of new populations and succession of fire-tolerant species. Twentieth Century fire management practices have shown that removal of fire from fire-adapted eco...

The Threshold for Toxicological Concern (TTC) is well-established for assessing human safety but has only recently been explored in the ecological context. Ecological Thresholds for Toxicological Concern TTC (eco-TTC) summarize the wealth of ecotoxicological information as Predi...

The purpose of this study was to determine if an interdisciplinary team using a qualitative proper functioning condition (PFC) assessment protocol could identify and reverse significant detrimental ecological alterations which occurred within Gertie's Creek watershed, Ontario, Ca...

This report presents multiple lines of inquiry focused on improving the public’s use of ecosystem goods and services (EGS) concepts, data, and tools for addressing environmental, social, and economic problems. The case studies and data tools and models in the report highlight the...

Mosquito-borne diseases are changing in geographic extent and increasing in incidence due to human-mediated ecological changes and a changing climate. In order to surveil, predict, and mitigate these diseases, it is important to study the ways in which ecosystems interact with th...

Vector-borne diseases are increasing in geographic extent and incidence in the United States and worldwide. The combined impacts of human-mediated ecological change and a changing climate provide new habitats for disease vectors, enable the rapid spread of infectious disease, and...

Natural ecosystems perform fundamental life-support services upon which human civilization depends. However, many people believe that nature provides these services for free and therefore, they are of little or no value. One nearly forgotten ecosystem service is ecotherapy &ndash...

Until somewhat recently there was limited awareness about the impact of soils on human health, ecosystems, and economy. Only in the second half of the twenty century the world awaked for the poor condition of soils, and to its several threats (e.g. soil contamination), as well as...

Ammonia (NH3) is the most abundant alkaline gas in the atmosphere and a precursor to ammonium (NH4+) aerosols. NH3 and NH4+ also deposit to ecosystems, degrading the environment through eutrophication of surface waters and soil acidification. Agricultural activities dominate anth...
