DATA PRODUCT INFORMATION ------------------------ ID: NEON.DOM.SITE.DP1.10072.001 Name: Small mammal box trapping Description: Individual- and trap-level data collected using box traps designed to capture small mammals NEON Science Team Supplier: TOS Abstract: This data product contains the quality-controlled, native sampling resolution data from NEON's small mammal sampling protocol. Small mammal abundance and diversity are sampled at regular intervals by NEON field technicians at core and relocatable sites. Here small mammals are defined based on a combination of behavioral, dietary, and size constraints, as the NEON design is limited to species sampled by box traps. This definition includes any mammal that is (1) nonvolant; (2) nocturnally active; (3) forages predominantly aboveground; and (4) is greater than 5 grams but less than approximately 500-600 g. In North America, this includes cricetids, heteromyids, small sciurids, and introduced murids. It does not include shrews, large squirrels, rabbits, or weasels, despite the fact that individuals of these species may be incidentally captured. Products resulting from this sampling include the species identification and unique identifier for each individual captured, as well as a suite of standard size measurements and reproductive condition data. Sample identifiers for any blood, ear, hair, whisker, fecal, and/or voucher samples collected are also provided. For additional details, see protocol [NEON.DOC.000481](http://data.neonscience.org/api/v0/documents/NEON.DOC.000481vJ): TOS Protocol and Procedure: Small Mammal Sampling and science design [NEON.DOC.000914](http://data.neonscience.org/api/v0/documents/NEON.DOC.000915vA): TOS Science Design for Small Mammal Abundance and Diversity. Brief Design Description: 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). Brief Study Area Description: These data are collected at all NEON terrestrial sites, except the site in Hawaii.

In order to protect privacy of NEON technicians while also providing a way to consistently identify different observers, we obfuscate each NEON personnel name by internally linking it to a unique string identifier (e.g., Jane Doe=ByrziN0LguMJHnInl2NM/trZeA5h+c0) and publishing only the identifier. CHANGE LOG ---------- Change Log Date: 2017-08-08 17:49:07.477: Issue Date: 2017-08-08 Date Resolved: 2017-08-08 Sites Affected: All Dates Affected: All Issue: As part of NEON's ongoing construction tasks, the processing pipeline for most data products for NEON's observational systems (terrestrial [TOS] and aquatic [AOS]) has been simplified to use a generic codebase. Data that were published previously have been reprocessed and republished using the generic code -- replacing data that had been processed using the original algorithms described in Algorithm Theoretical Basis Documents (ATBDs). Consequently, data are in a new format including, in many cases, different data fields. Details of the new processing pipeline can be found in http://data.neonscience.org/api/v0/documents/OS_generic_transitions_vA and http://data.neonscience.org/api/v0/documents/Nicl_Language_DRAFT. 2017-08-08 17:44:24.731: Issue Date: 2014-11-20 Resolved Date: 2014-11-20 Sites Affected: All Dates Affected: All Issue: Removed values in derived field pregnancyStatus where sex = ‘M’ . This issue is no longer relevant after the code update and reprocessing on 2017-08-08. ADDITIONAL REMARKS ------------------ Queries for this data product will return data collected during the date range specified. Per trapping grid data are provided in the table, mam_perplotnight, with associated per trap per night data provided in the mam_pertrapnight table. The tables can be joined by the nightuid field. Duplicates may exist where protocol and/or data entry abberations have occurred; users should check data carefully for anomalies before joining tables. NEON DATA POLICY AND CITATION GUIDELINES ---------------------------------------- The data contained in this file are considered provisional. Updates to the data, QA/QC and/or processing algorithms over time will occur on an as-needed basis. Please check back to this site for updates tracked in change logs. Query reproducibility on provisional data cannot be guaranteed. Please visit http://data.neonscience.org/data-policy for more information. Starting in 2020 or earlier, NEON will begin to offer static versions of each data product, annotated with a globally unique identifier. Versioned IS and OS data will be produced by reprocessing each IS and OS data product from the beginning of the data collection period to approximately 12-18 months prior to the reprocessing date (to allow for calibration checks, return of external lab data, etc.). The reprocessing step will use the most recent QA/QC methods and processing algorithms. Versioned AOP data will be produced by reprocessing the entire AOP archive as advances in algorithms and processing technology are incorporated. This will typically occur in the northern winter months, between flight season peaks, and will be on the order of every 3 to 5 years in frequency.
