Effective conservation and management decisions for habitats require information about the distribution of multiple species but such data is expensive to obtain; this often limits data collection to just a few, high-profile species. Environmental DNA (eDNA) sampling can be more sensitive, and less expensive, than traditional sampling for aquatic species, and a single sample potentially contains DNA from all species present in a waterbody. Cost-savings accrue if eDNA collected for detecting a particular species can be repurposed to detect additional species. This study tested the feasibility of repurposing and re-analyzing already collected samples.
The website provides:
1) A large list of supporting science behind eDNA sampling.
2) The recommended field protocol for eDNA sampling and the equipment loan program administered by the NGC.
3) A systematically-spaced sampling grid for all flowing waters of the U.S. in a downloadable format that includes unique database identifiers and geographic coordinates for all sampling sites. Available for download in an Geodatabase or available by ArcGIS Online map. This sampling grid can be used to determine your field collection sites to contribute.
4) The lab results of eDNA sampling at those sites where project partners have agreed to share data.
