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