What happens to small mammals when grass is mown, and the , mechanisms of habitat selection by the hispid cotton rat (sigmodon hispidus matt liebman and paula r westerman, seasonal patterns in post‐dispersal seed predation of abutilon theophrasti and setaria faberi in three cropping. Effects of landscape spatial structure on movement patterns of the hispid cotton rat, sigmodon hispidus landscape ecology 14: 53-65 landscape ecology 14: 53-65 135. My major research interests are in spatial ecology, specifically how individual animals move across the landscape and the effects of these movements on population processes for the past five years, i have studied the movement ecology of eastern painted turtles (chrysmys picta picta) living in ponds.
The hispid cotton rat (sigmodon hispidus hereafter, cotton rat) is one of the most common small mammals in the southeastern united states and is an important prey species for several of the region’s predators. Souri—the hispid cotton rat (sigmodon hispidus) is a bailey (1902) was the firstto document movement of s hispidus into the central plains by documenting individuals shifting distribution patterns of mammals in nebras-ka transactions of the nebraska academy of science 26:55–84.

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 (sigmodon. Small mammal communities in eastern redcedar forest during a recent investigation involving the use of radiotelemetry to study the movement patterns of the hispid cotton rat (sigmodon hispidus), we documented several occurrences of predation on transient cotton rats.

The yuma hispid cotton rat is a thick bodied rodent, with a medium-length tail slightly shorter than its head and body their ears barely project above their fur, and their tail is sparsely haired their ears barely project above their fur, and their tail is sparsely haired. For small mammals, food is likely to be a critical resource population densities should vary directly with food abundance, but the underlying demographic changes are more difficult to predict we experimentally increased food available to populations of hispid cotton rats, sigmodon hispidus, to examine how rates of recruitment and.
Effects of anthropogenic factors in eastern deciduous forest we study how fragmentation of eastern deciduous forest affects density, reproduction, movement patterns, parasitism, and foraging dynamics of small mammals. Hispid cotton rat (sigmodon hispidus) was the dominant small mammal identified in the scat, which is not surprising considering it is likely the most abundant native mammal in georgia and is found state-wide. In kansas hispid cotton rat density ranges were 02 to 21 rats per hectare in grassland  the highest estimated density was 654 hispid cotton rats per hectare in favored habitat [ 22 ] in a study of the effects of habitat patchiness on movement, hispid cotton rats preferred only the largest patches which were 165 feet (50 m) by 330 feet. The authors studied the movements of cotton rats and cotton mice in experimental landscapes at the srs in order to determine the effects of fragmentation and connectivity between habitat patches on dispersal movements and population dynamics densities between connected and isolated patches were not.
As part of our ongoing long-term studies of small mammals on the konza prairie biological station in eastern kansas, we have examined the magnitude and pattern of long-term variation in abundance of the hispid cotton rat (sigmodon hispidus. Small mammals were more abundant in “fed” versus “unfed” experimental plots on our study site (morris et al 2011), which may have improved the physiological condition of individual predators that hunted near bait piles.
