Mammal Collection (Vouchers [Standard Sampling at Diversity Plots]) (NEON-MAMC-VDP)
This collection contains small mammal vouchers collected during small mammal sampling at diversity plots (NEON sample classes: mam_voucher_in.voucherSampleID.mam). 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) and, at sites in Puerto Rico, larger wire traps suitable for catching Rattus spp. (model 201, Tomahawk Live Trap, Hazlehurst, WI, 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. Where used, wire traps are used only in alternate bouts of trapping and placed at every other trap station in the 10 x 10 grid, such that a total of 50 wire traps are set. 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). Only mortalities and individuals that require euthanasia due to injuries are vouchered. The NEON Biorepository receives whole frozen specimens and prepares vouchers as either study skins with skulls (or full skeletons) or in 95% ethanol.
