Ecology of small mammals in a flatwoods habitat in north-central Florida, with emphasis on the cotton rat (Sigmodon hispidus). American Museum novitates ; no. 2544

"The small mammals of a pine flatwoods habitat in north-central Florida were studied during 1960 to 1972. Didelphis virginiana, Cryptotis parva, Oryzomys palustris, Reithrodontomys humulis, Peromyscus gossypinus, and Rattus rattus were live-trapped on the study plot. Lasiurus seminolus, Scalopus aquaticus, Sylvilagus floridanus, Procyon lotor, and Geomys pinetis were also recorded. Of the trappable species, Cryptotis, Reithrodontomys, Peromyscus, and Sigmodon were considered regular residents of the study plot, and data are given on their trappability, populations, body weight, sex ratio, reproduction, longevity, and movements. A portion of the study plot was burned in 1960, and the responses of the small mammal populations are documented. Information on mammals in various types of Florida flatwoods habitats is summarized. Data on Sigmodon hispidus from the present study and the literature are reviewed in an attempt to assess the relative influence of major climatic factors and local environmental conditions on selected ecological and life history parameters of this species. The relative importance of natality and mortality in population fluctuations of Sigmodon is also discussed"--P. 3.
