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 piscivorous birds. This has been done in conjunction with researchers in the northeastern United States and Canada concerned with the threat of mercury and/or threats to the common loon in this geographic area. Database components are linked by lake name and location. The database currently contains watershed and lake characteristics, water and sediment chemistry data, fish contaminant concentration data, mercury concentrations in loon tissues, and loon productivity data. This data was obtained from projects conducted for varying purposes, by different investigators. It is expected that the database will be further expanded over time. 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 in vertical format by clicking on 'Access the Wildlife Database.' The data can be searched and downloaded in this configuration. Alternatively, the data can be downloaded in horizontal (spreadsheet format) by clicking 'Access Selected Data in ASCII format.'
