NEON Biorepository Mammal Collection (Pathogen Extracts [Ear Tissue])

Citation

Description

This collection contains genetic extracts from ear punch (tissue) samples that were collected from select small mammals during small mammal sampling and sent for testing for tick-borne pathogens (NEON sample class: rpt2_pathogentesting_in.earExtract). 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 archive, DNA analysis or pathogen testing. Ear punches are collected once per life of an individual. Ear samples are placed on dry ice in the field and stored at -80 degrees Celsius. Ear tissue samples are tested via PCR individually for a variety of tick-borne pathogens. Pathogen extracts from the University of Massachusetts Laboratory of Medical Zoology are archived at the NEON Biorepository in 2 mL cryovials and stored at -80 degrees Celsius.
