A research on the movement pattern of the small mammal the hispid cotton rat

Management of amphibians, reptiles, and small mammals in North America: As ROMPA decreased, distances between patches of favorable habitat high cover increased owing to a greater proportion of unfavorable mowed habitat.

Traps were baited with peanut butter and rolled oats Kaufman et al. The role of micro-habitat selection by S.

They do not breed in the coldest winter months. Mammals of longleaf-slash pine stands in central Louisiana. We trapped for 4 consecutive nights in spring and in autumn. Publication Notes This article was written and prepared by U.

In Texas, grassy areas with some shrubs were preferred in spring and areas with more shrubby cover were preferred in fall.

Disjunct populations occur in southeastern Arizona and extreme southeastern California into Baja California Norte.

Hispid cotton rat

Patches of habitat types in this coastal prairie habitat are contiguous, with no matrix habitat. This paper map was digitized into a computer-based map and used to identify habitat patches occupied by individuals at each telemetry fix. Given that fire increases production of grasses in tallgrass prairie Knapp et al.

Sex, age, reproductive status, and mass were recorded for each cotton rat. The use of disturbed areas was probably important in the recent invasion of hispid cotton rats into north-central Kansas from the northern presettlement limit of their range in Oklahoma. They are strongly associated with grassy patches with some shrub overstory and they have little or no affinity for dicot-dominated patches.

We also described temporal variability by calculating the standard deviation of logarithm base 10 of abundance SDlog— Ostfeld Advanced Search Abstract Sigmodon hispidus, the hispid cotton rat, has a wide geographic distribution and has been the focus of numerous ecological studies; however, patterns of genetic divergence within this species remain largely unknown.

The Effects of Habitat Fragmentation on Small Mammal Populations

AFLP has been used in studies of genetic variation within populations Mueller and Wolfenbarger and in investigating the congruence of mtDNA gene trees and species trees, an application that well suits the current study.

University of Florida Press: Wild mammals of Colorado. Animals were livetrapped in a 2-ha field over 3-day periods from winter through fall The presence of the cover had no effect on seasonal recruitment or spring-summer mortality; however, autumn-winter mortality was greatly reduced with the cover in place.

Hispid cotton rat

The mean hispid cotton rat population density range for all studies was 5. If the confidence interval of the observed use of a habitat type overlapped availability of a habitat type, that habitat was used in proportion to its availability.

Euclidian distance was computed between sequential fixes.

However, turns relative to straight-ahead movements for females, but not males, were fewer in mixed habitats than in monocot or dicot habitats suggesting directed foraging rather than area-restricted search. The mammals of North America.Effects of mammalian predator exclusion and supplemental feeding on space use by hispid cotton rats Food resources and predation can influence various aspects of the ecology of small mammals, including movement and space-use patterns.

feeding and mammalian predator exclusion affected size and exclusivity of hispid cotton rat. In Kansas hispid cotton rat density ranges were to 21 rats per hectare in grassland; the highest estimated density was hispid cotton rats per hectare in favored habitat.

[15] In a study of the effects of habitat patchiness on movement, hispid cotton rats preferred only the largest patches which were feet (50 m) by feet (50× m).Class: Mammalia. Original Article Small Mammal Use of Field Borders Planted as Beneficial Insect Habitat CHRISTOPHER E.

MOORMAN,1 Fisheries, Wildlife, and Conservation Biology Program, Department of Forestry and Environmental Resources, North Carolina State University, Raleigh, NCUSA. Tree islands in the Everglades prairie provided a unique opportunity to study how patch dynamics affect population processes in two small mammal species, the marsh rice rat and hispid cotton rat.

Effects of landscape spatial structure on movement patterns of the hispid cotton rat (Sigmodon hispidus) The The movements of small mammals in fragmented importance of corridors will depend on the ecology landscapes have received increased attention in recent and behavior of a species, and on the nature of the years (Merriam.
