Key ecological responses to nitrogen are altered by climate change (JOURNAL)
Here we review the effects of nitrogen and climate (e.g. temperature and precipitation) on four aspects of ecosystem structure and function including hydrologic-coupled nitrogen cycling, carbon cycling, acidification and biodiversity.
Can interpreting sediment toxicity tests a mega sites benefit from novel approaches to normalization to address batching of tests? (PRESENTATION)
Sediment toxicity tests are a key tool used in Ecological Risk Assessments for contaminated sediment sites. Interpreting test results and defining toxicity is often a challenge. This is particularly true at mega sites where the testing regime is large, and by necessity performed ...

Quantitative Microbial Risk Assessment Tutorial - SDMProjectBuilder: Import Local Data Files to Identify and Modify Contamination Sources and Input ParametersUpdated 2017 (PUBLISHED REPORT)
Twelve example local data support files are automatically downloaded when the SDMProjectBuilder is installed on a computer. They allow the user to modify values to parameters that impact the release, migration, fate, and transport of microbes within a watershed, and control delin...
Quantitative Microbial Risk Assessment Tutorial - Navigate the SDMPB and Identify an 8-digit HUC of Interest - Updated 2017 (PUBLISHED REPORT)
This tutorial reviews some of the screens, icons, and basic functions of the SDMProjectBuilder (SDMPB) that allow a user to identify an 8-digit HUC (HUC-8) of interest from which a pour point or 12-digit HUC (HUC-12) can be chosen for a microbial assessment. It demonstrates how t...
USDA Collaboration with EPA/ORD (PRESENTATION)
For more than seven years, EPA scientists have been leveraging the USDA Environmental Policy Integrated Climate (EPIC) model to reduce uncertainty in our estimates of agricultural emissions, ambient PM concentrations and subsequent human exposure risk. This presentation summariz...
