These layers were generated by compiling locations from published and gray literature where nesting colonies were sampled for mtDNA studies. We accepted genetic stock definitions as described by the original sources, rather than attempting to standardize or prioritize methodologies or interpretations. For a full list of attributes associated with each site please download the associated metadata. If you have information on additional sampled sites, please use the feedback button to provide as much of this information as possible. Any suggested changes must be accompanied by relevant citations to be accepted and incorporated. Feedback will be reviewed and used to update these distributions periodically.
Full citations are available in an EndNote library.
The library is also included in the zipped file of the layer shapefiles.
