We used large, nonfolding Sherman live traps to survey small mammals in native tallgrass prairie habitats (by traplines and grids), woodland habitats (by traplines and grids) and planted brome fields (traplines only). Eighty-seven least shrews were captured over the 29 years of surveys (ca. 350,000 trap nights). Almost all captures (98%) occurred in prairie habitat; 80% of all captures occurred on a prairie grid during a 5-year period. Least shrews on prairie traplines were captured in a variety of topographic positions (upland, hillside slope and lowland) and in burned and unburned prairie, but not in prairie grazed by bison. We captured individuals that ranged in body size from 2.5&ndash;8.0 g. The mean body mass of all captured least shrews was 4.7 g (excluding pregnant females) and, when only adults were included (excluding pregnant females), it was 5.1g. We noted 13 pregnancies among 12 females; the earliest pregnancy was recorded in mid-April and latest in mid-October. Most pregnancies (ca. 70%) were recorded in two months, July and September. Lactating females that were not pregnant were larger in size (5.5 g) than non-reproductive females (4.4 g). Response of least shrews to live traps was not neophobic; and, in fact, about 30% of the shrews were captured on day 1 of a 4-day trapping period on prairie sites. Our data add information about attributes of least shrews living in natural habitats, such as the tallgrass prairie, and support two previous studies, which suggested that least shrews are rare on Konza Prairie.</p>10aabundance10abody size10aCryptotis parva10afire10aGrazing10aplanted brome fields10areproduction10atallgrass prairie10atrap response10awoodland habitat1 aKaufman, G.A.1 aKaufman, D.W.  uhttps://doi.org/10.1660/062.114.010402733nas a2200361   4500008004100000245007500041210006900116260005100185300001300236520157300249653002501822653002001847653002001867653000901887653002401896653001601920653004001936653001601976653002501992653001702017653002202034653002502056653002902081653002502110653002302135653001502158653002002173100001902193700001802212700001802230700001902248856010402267       1999                        eng d00aRare species of small mammals in northeastern Kansas tallgrass prairie0 aRare species of small mammals in northeastern Kansas tallgrass p  aKearney, NEbUniversity of Nebraska at Kearney  a120 -1263 aWe sampled small mammals in native tallgrass prairie habitat from autumn 1981 to spring 1998 on Konza Prairie Research Natural Area, Kansas. In 130,560 trap-nights, we captured 14 species of small mammals. In decreasing order of abundance, the relatively common species were the deer mouse (Peromyscus maniculatus), western harvest mouse (Reithrodontomys megalotis), Elliot's short-tailed shrew (Blarina hylophaga), white-footed mouse (P. leucopus), prairie vole (Microtus ochrogaster), thirteen-lined ground squirrel (Spermophilus tridecemlineatus), and hispid cotton rat (Sigmodon hispidus). Likewise, rare species were the southern bog lemming (Synaptomys cooperi), hispid pocket mouse (Chaetodipus hispidus), eastern woodrat (Neotoma floridana), house mouse (Mus musculus), plains harvest mouse (Reithrodontomys montanus), least shrew (Cryptotis parva), and meadow jumping mouse (Zapus hudsonius). Relative abundances of the rare species ranged from 0.002 (individuals/trapline/sampling period) for the meadow jumping mouse to 0.112 for the southern bog lemming. All rare species combined comprised approximately 2% of the small mammal community in grasslands on Konza Prairie. Southern bog lemmings selectively used sites that were left unburned for 2-3 years in contrast to those burned annually and those unburned for s 4 years. Time since fire had no detectable effect on numbers of individuals for the other 6 rare species. In addition, southern bog lemmings, eastern woodrats, and hispid pocket mice were distributed nonrandomly with respect to topography.
