Bk. Clark et al., DIFFERENTIAL USE OF ROADSIDE FENCEROWS AND CONTIGUOUS PASTURES BY SMALL MAMMALS IN SOUTHEASTERN OKLAHOMA, The Southwestern naturalist, 41(1), 1996, pp. 54-59
We assessed differential use of roadside fencerows and contiguous past
ures by small mammals in southeastern Oklahoma during September 1991,
February 1992, and May 1992. Eight species of rodents and shrews were
represented in 338 individuals captured; however, the four most common
species comprised 96% of all captures (Sigmodon hispidus, 64% of all
captures; Peromyscus maniculatus, 13%; Mus musculus, 12%; and Reithrod
ontomys fulvescens, 7%). No seasonal differences in use of fencerows a
nd pastures were found for total captures of any of these four species
. Sigmodon hispidus, M. musculus, and R. fulvescens selectively used f
encerows; P. maniculatus chose pastures. No differences between males
and females in use of fencerows and pastures were noted for any specie
s. However, significant differences were found in use of fencerows and
pastures among different size classes of S. hispidus; small males (<
60 and 60-110 g) and females < 60 g and > 110 g were significantly mor
e abundant in fencerows than pastures.
