These large cotton rat
populations could be sustained early in succession due to the abundant herbaceous habitat, but the increasing dominance of loblolly pines and subsequent decrease in herbaceous vegetation reduced the ability of the cotton rat
population to recover from its seasonal low in the spring of 2005.

The cotton rat
(Sigmodon hispidus) is a permissive small animal model of human metapneumovirus infection, pathogenesis, and protective immunity.
Mexican spiny pocket mouse, white-footed mouse [Peromyscus leucopus] and hispid cotton rat
[Sigmodon hispidus]) that were recaptured frequently enough to permit calculation of the Mean Maximum Distance Moved (MMDM).
Abstract: We investigated the swimming abilities of three Costa Rican dry forest rodents (Coues' rice rat, Oryzomys couesi, hispid cotton rat
, Sigmodon hispidus, and spiny pocket mouse, Liomys salvini) associated with a large marsh, Laguna Palo Verde, using 90 s swim trials in a plastic container.
During a radiotelemetry study of the hispid cotton rat
(Sigmodon hispidus), we documented five predation events by reptilian and avian predators.
If so, the overall cotton rat
and prairie vole populations on the area may actually be metapopulations, with several distinct local populations linked by dispersal.
Goertz (1971) presented a compelling explanation for the brief surge in woodland vole densities: the extirpation of a local cotton rat
population due to extreme winter weather enabled woodland voles to flourish for a year or more.
maniculatus), the western harvest mouse (Reithrodontomys megalotis), the hispid cotton rat
(Sigmodon hispidus), the fulvous pygmy rice rat (Oligoryzomys fulvescens), and 122 other species in the Neotominae or Sigmodontinae (16).
Densities of the hispid cotton rat
(Sigmodon hispidus) were significantly greater in the Muhlenbergia habitat than in King Ranch bluestem.
New Helminth records from the cotton rat
Sigmodon hispidus, including a new species Strongyloides sigmodontis.
We examined the microhabitat associations of the hispid cotton rat
(Sigmodon hispidus) and white-footed mouse (Peromyscus leucopus).
