This data set descibes results from a small mammal thesis trapping project in Alaska during June-August, 2010-2011. Twelve locations were sampled using a mix of Sherman, Museum Special and pitfall traps, providing presence/absence and basic index of abundance information. Seventeen species were trapped (species list provided at the bottom of the abstract). Data are useful for morphometrics, distribution, species richness and predictive modeling questions. The data is also designed to model stable isotope information distributions (isoscapes). Sampling locations were selected on the basis of representative sampling of biomes and three elevational categories in Alaska The following sites are included: Canning River Delta ((lattitude 70.11782 N, longitude -145.84905 W, elevation 10 m), Botenintin Lake (latitude 60.51768 N, -150.55368 W, elevation 112), Petersville Rd. (latitude 62.34189 N, longitude -150.60069 W, elevation 298), Little Nelchina River (latitude 61.99025 N, longitude -146.94612 W, elevation 658), Thompson Pass (latitude 61.13413 N, longitude -144.72609 W, elevation 887 m), Isabel Pass (latitude 63.19046 N, longitude -145.52866 W, elevation 1005 m), Nenana River (latitude 63.39118 N, longitude -148.56018 W, elevation 738 m), Upper Tanana River (latitude 63.36932 N, longitude -142.57564 W, elevation 677 m), Twelve-Mile Summit (latitude 65.41095 N, longitude -145.98810 W, elevation 1119 m), Bonanza Creek Experimental Forest (latitude 64.70984 N, longitude -148.29433 W, elevation 133 m), Atigun Pass (latitude 68.10358 N, longitude -149.50903 W, elevation 1132 m), Sagwon Bluffs (latitude 69.41339 N, longitude -148.72858 W, elevation 279 m). Species were described with the Integrated Taxonomic Information System (ITIS.org). For wider context and information, please see also related datasets about plot descriptions, bird point count data, plant collections and a plot-specific species list. The following 17 species were trapped: Northern Colleared Lemming (Dicrostonyx groenlandicus;TSN180328), Northern red-backed vole (Clethrionomys (Myodes) rutilus; TSN 180293), Tunrda vole (Microtus oeconomus; TSN 180298), Northern bog lemming (Synaptomys borealis; TSN 180323), Red squirrel (Tamiasciurus hudsonicus; TSN 180166), Common shrew (Sorex cinereus; TSN 179929), Meadow vole (Microtus pennsylvanicus; TSN 180297), Singing vole (Microtus miurus; TSN 180309),
American Pygmy Shrew (Sorex hoyi; TSN 179946), Tunrda Shrew (Sorex tundrensis;TSN 179957), Ermine (Sorex tundrensis; TSN 180555), Taiga vole (Microtus xanthognathus; TSN 180301), Long-tailed vole (Microtus longicaudus; TSN 180299), Alaska Tiny Shrew (Sorex yukonicus; TSN 555663), Ground squirrel (Spermophilus parryii; TSN 180146), Barren Ground Shrew (Sorex ugyunak; TSN 552509).

Methodology_Description:
This study follows standard procedures in small mammal trapping. 100 traps are set 10m apart, and 3 of such such trap lines (loops) are run, and remain open for 5 days. Traps are checked morning and evening, and specimens are identified and processed subsequently in a camp.
