NEON Biorepository Mammal Collection (Ear Tissue)

This collection contains ear punch samples collected from small mammals during small mammal sampling (NEON sample class: mam_pertrapnight_in.earSampleID). Small mammal sampling is based on the lunar calendar, with timing of sampling constrained to occur within 10 days before or after the new moon. Typically, core sites are sampled 6 times per year, and relocatable sites 4 times per year. Small mammals are sampled using box traps (models LFA, XLK, H.B. Sherman Traps, Inc., Tallahassee, FL, USA). Box traps are arrayed in three to eight (depending on the size of the site) 10 x 10 grids with 10m spacing between traps at all sites. Small mammal trapping bouts are comprised of one or three nights of trapping, depending on whether a grid is designated for pathogen sample collection (3 nights) or not (1 night). A subset of captured small mammals have tissues sampled (ear punch) for DNA analysis. A subset of those tissue samples are sent either for pathogen testing, or to the Canadian Centre for DNA Barcoding. The remaining samples are archived in the NEON Biorepository at -80 degrees Celsius. Ear punches are collected once per life of an individual.
