Factors Affecting Distribution and Removal Rates of Small Mammals in a Lowland Swamp Forest

Gray C. Smith, John B. Gentry, Donald W. Kaufman, and Michael H. Smith



Small mammals were snap-trapped on an octagon-shaped line transect 176 m on a side located in a lowland mesic-hardwood forest in the Southeastern United States.  Two traps were set at each of 128 stations and 52 Ochrotomys nuttalli, 38 Peromyscus gossypinus, and 18 Blarina brevicauda were removed during a 28-day period.  Differential removal rates for the three species were observed.  The probability of capture seemed to vary as a function of microhabitat differences, species specific trap neophobia, and weather changes over the 28-day trapping period.  Social interaction was not a factor in changing removal rates, since each species appeared to occur in-different microhabitats.  Cotton mice were associated with fallen trees (logs), golden mice with vines and short-tailed shrews with high amounts of leaf litter.
