“…The clearcut areas within the harvested stands were invaded by small mammals typical of early successional habitats. Cotton rats, an edge/old-field species (Pagels et al, 1992), tend to favor habitats with dense herbaceous understory plants (Atkeson and Johnson, 1979;Cameron and Spencer, 1981;Langley and Shure, 1980;Thurmond and Miller, 1994) and this species occurred in greatest numbers in our recently clearcut areas. Cotton mice, a species that uses clearcut habitats more than corridor habitats (Bayne and Hobson, 1998), were captured more often in recently clearcut areas than in adjacent forest patches.…”

“…Prevalence of antibody in the species was low (one of 32 total; one of nine captured at Fort Larned NHS). Nevertheless, its local abundance and affinity for disturbed grassy habitats 22,24 would bring cotton rats into frequent contact with humans and suggests a high potential for sporadic cases of HPS within the range of the species.…”

Abstract. Hantavirus activity in 39 National Parks in the eastern and central United States was surveyed by testing 1,815 small mammals of 38 species for antibody reactive to Sin Nombre virus. Antibody-positive rodents were found throughout the area sampled, and in most biotic communities. Antibody was detected in 7% of 647 deer mice (Peromyscus maniculatus), 2% of 590 white-footed mice (P. leucopus), 17% of 12 rice rats (Oryzomys palustris), 3% of 31 cotton rats (Sigmodon hispidus), and 33% of 18 western harvest mice (Reithrodontomys megalotis). Antibody was also found in three of six species of voles, and in one of 33 chipmunks (Tamias minimus). Prevalence among Peromyscus was highest in the northeast. Although few cases of hantavirus pulmonary syndrome have been identified from the eastern and central regions, widespread infection in reservoir populations indicates that potential exists for human infection throughout much of the United States.

“…Some animals, however, are very plastic and can be diurnal in some environmental conditions and nocturnal in others Dayan, 2003, 2008]. Examples include microtine rodents that are diurnal in winter and nocturnal in the summer [Rowsemitt et al, 1982] and cotton rats in which patterns differ across individuals and change over time [Camerson and Spencer, 1981;Johnston and Zucker, 1983;Hoogenboom et al, 1984;Hagenauer and Lee, 2008]. Plasticity can be promoted by changes in masking or in circadian mechanisms [Mrosovsky and Hattar, 2005].…”

The Substructure of the Suprachiasmatic Nucleus: Similarities between Nocturnal and Diurnal Spiny Mice

et al. 2010

Evolutionary transitions between nocturnal and diurnal patterns of adaptation to the day-night cycle must have involved fundamental changes in the neural mechanisms that coordinate the daily patterning of activity, but little is known about how these mechanisms differ. One reason is that information on these systems in very closely related diurnal and nocturnal species is lacking. In this study, we characterize the suprachiasmatic nucleus (SCN), the primary brain structure involved in the generation and coordination of circadian rhythms, in two members of the genus Acomys with very different activity patterns, Acomys russatus (the golden spiny mouse, diurnal) and Acomys cahirinus (the common spiny mouse, nocturnal). Immunohistochemical techniques were used to label cell bodies containing vasoactive intestinal polypeptide (VIP), vasopressin (VP), gastrin-releasing peptide (GRP) and calbindin (CalB) in the SCN, as well as two sets of inputs to it, those containing serotonin (5-HT) and neuropeptide Y (NPY), respectively. All were present in the SCN of both species and no differences between them were seen. On the basis of neuronal phenotype, the SCN was organized into three basic regions that contained VIP-immunoreactive (-ir), CalB-ir and VP-ir cells, in the ventral, middle and dorsal SCN, respectively. In the rostral SCN, GRP-ir cells were in both the VIP and the CalB cell regions, and in the caudal area they were distributed across a portion of each of the other three regions. Fibers containing NPY-ir and serotonin (5-HT)-ir were most concentrated in the areas containing VIP-ir and CalB-ir cells, respectively. The details of the spatial relationships among the labeled cells and fibers seen here are discussed in relation to different approaches investigators have taken to characterize the SCN more generally.
