    Wild adult and recruit Kelletia kelletii samples from 2015 to 2017 (KW connectivity project)

    Tissue samples of the North American west coast subtidal marine gastropod Kellet’s whelk, Kelletia kelletii, were collected by Crow White and colleagues to support population genomics research. A total of 6,900 samples from 36 sites across the species’ geographic range (Monterey, California, USA to Isla Asunsion, Baja California, Mexico) were collected during the summer months of June, July, and August in 2015, 2016, and 2017. Samples were collected by hand at sub-tidal reefs using SCUBA. Adult samples (n=4,624) represent ~60-100 mg tissue removed from the foot of the organism with a modified scalpel. All sampled adults were at least 60 mm in shell length. Adult samples at each site were stored together in a single 15-ml tube. Recruit samples (n=2,276) represent the entire organism. All recruit samples were a maximum of ~30 mm shell length. Recruit samples at each site were stored together in a ziplock bag. All samples were frozen in the field in a cooler with dry ice and/or container with liquid nitrogen, then transported to California Polytechnic State University and stored long-term in a minus ~70C freezer in the Biological Sciences Department.
