The United States Environmental Protection Agency's (EPA) Global Climate Research Program (GCRP) is determining the effects of climate change on terrestrial ecosystems. his paper describes a general ecological risk assessment model as well as specific conceptual models for urrent...

Dpeletion of stratospheric O3 layer should result in enhanced levels of ultraviolet-B (UV-B) radiation at the earth's surface compared to present, with potentially damaging effects on biological systems. his paper briefly summarizes some key findings for UV-B effects on terrestri...

The process of translating scientific information into timely and useful insights that inform policy and resource management decisions, despite the existence of uncertainties, is a difficult and challenging task. Policy-focused assessment is one approach to achieving this end. ...

A compelling aspect of the deterioration of coral reefs is the phenomenon of coral bleaching. Through interactions with other factors such as sedimentation, pollution, and bacterial infection, bleaching can impact large areas of a reef with limited recovery, and it might be induc...

<h2>Abstract</h2><p>Disturbances of climatic and ecological systems can present risks to human health, which are becoming more evident from health studies linked to climate variability, landuse change and global climate change. Waterborne disease agents, such as <i>Giardia</i> cy...

A number of multimedia modeling frameworks are currently being developed. The Multimedia Integrated Modeling System (MIMS) is one of these frameworks. A framework should be seen as more of a multimedia modeling infrastructure than a single software system. This infrastructure do...

A session on "Understanding and Managing Effects of Global Atmospheric Change" will be held at the Fifth Symposium of the U.S. EPA National Health and Environmental Effects Research Laboratory. The Symposium topic is "Indicators in Health and Ecological Risk Assessment." The s...

The rate of change in Northern Hemisphere atmospheric temperature in the past century relative to the preceding millennium strongly suggests that we are in a period of rapid global climate change. The mid-Atlantic region is quite sensitive to larger scale climate variation, which...

Regional Vulnerability Assessment (ReVA) is an approach to regional-scale ecological risk assessment that is currently under development by EPA's Office of Research and Development. The pilot assessment will be done for the mid-Atlantic region and builds on data collected for th...
