Distribution and ecology of the hispid
and least cotton rats in New Mexico.
Following a well documented spread through Kansas, the hispid
cotton rat was first captured in Nebraska in 1958, in Richardson County (Jones 1964).
We caught one southern flying squirrel in eastern redcedar forest whereas we caught fulvous harvest mice, hispid
cotton rats, and least shrews (Cryptotis parva) exclusively in unforested habitats.
Results--In 3,777 trap nights we captured 311 small mammals of five species (Table 1), listed in decreasing order of abundance: hispid
cotton rat (S.
Although Peter's climbing rat and hispid
cotton rat were represented in trapping and pellets, they showed inverse abundance patterns: we captured only one specimen of the former, and two of the latter.
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).
Also, the perigynia of bog plants are, in general, longer and narrower than those of grassland plants; additionally, the perigynia of the former are smooth except sometimes sparingly hispidulous just beneath the beak, whereas those of the latter are distinctly appressed hispid
above the middle of the perigynium.
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.
lehmannii, which commonly has substrigose, hispid
, or sericeous leaves and phyllaries; stems shortly pilose or hispid
; and shorter, elliptic-ovate outer phyllaries.
During a radiotelemetry study of the hispid
cotton rat (Sigmodon hispidus), we documented five predation events by reptilian and avian predators.
Herbivorous rodents such as meadow voles and hispid
cotton rats (Sigmodon hispidus) dominate in grassy old fields; the latter is especially dominant throughout the southeastern United States (Cameron and Spencer, 1981).
The most common were deer mice (Peromyscus maniculatus; n = 19), white-footed mice (P leucopus; n = 18), and hispid
cotton rats (Sigmodon hispidus; n = 11).
