Risks of Multiple Stressors to Common Loons and Other Piscivorous Bird Populations
- This web application was developed as part of an EPA project to determine the risks of multiple stressors to common loons and other fish-eating birds. This has been done in conjunction with researchers in the northeastern United States and Canada concerned with the threat of mercury and habitat alteration to the common loon in this geographic area.
- The WILDLIFE DATABASE (WDB) contains watershed and lake characteristics, water and sediment chemistry data, fish contaminant concentration data, mercury concentrations in loon tissues, and loon productivity data. Data, linked by lake name and location, were assembled from projects conducted for varying purposes, by different investigators. The database web application is implemented using Oracle's application server using stored PL/SQL procedures, allowing the user to initially subset the data geographically and/or temporally, and to further subset the data by parameter, e.g., sediment analyte, chemical constituent, species, etc. The data can be viewed, searched and downloaded in vertical format by clicking on 'Access the WDB'. Alternatively, the data can be downloaded in horizontal (spreadsheet format) by clicking 'Access Selected Data from the WBD in ASCII format.‘
- The MERGANSER MAPVIEWER (MMV) displays results of a model that estimates fish mercury in over 4000 New England lakes. This model, named MERGANSER (MERcury Geo-spatial AssessmeNTtS for the New England Region (Shanley et al. Environ. Sci. Tech. 2012; EPA R1 Contact, Alison Simcox, firstname.lastname@example.org), was developed by an EPA lead collaboration using data from the WILDLIFE DATABASE. The data can be searched and downloaded by clicking on ‘Access the MDV’.
