Understanding space use patterns of wildlife may be useful to spatially plan habitat management options and understand how species use resources on a landscape. Spatial fidelity can be defined as the tendency of an animal to maintain similar space use patterns among periods of interest and can be described in terms of differences in dispersion of points and shift in central tendency. However, little information is available concerning spatial fidelity in wild turkeys (Meleagris gallopavo). Therefore, we investigated seasonal spatial fidelity of male and female eastern wild turkeys (M. g....

Bobcat (Lynx rufus) home range is generally considered to be a function of habitat quality, but there have been few published studies that explicitly address this idea. We used empirically developed bobcat habitat models to predict habitat quality within bobcat home ranges on 2 study areas in central Mississippi. We then assessed the relationship between home range size and habitat quality. Habitat quality and variability of habitat quality were not (P>0.10) predictors of home range size. Moreover, habitat quality differed statistically (P<0.01), and habitat composition differed...

Home range size quantifies space needed by an animal in a given area and time. Because fox squirrel (Sciurus niger) home range estimates in the Southeast are rare, I radio-monitored fox squirrels to determine their seasonal and composite (i.e., total duration of monitoring) home range size in southwest Georgia between March 1998 and September 1999. There was no sex by season interaction (P =0.11). Male seasonal and composite home ranges (35.8±4.4 ha and 37.0±3.6 ha, respectively) were larger (P <0.001) than female home ranges (seasonal = 13.3±1.5 ha, composite =21.0±6.3 ha). Seasonal...

Fox squirrels (Sciurus niger) are an important species in longleaf pine (Pinus palustris) forests. We estimated fox squirrel density within 6 minimally disturbed longleaf pine strands, examined association between fox and gray squirrels (S. carolinensis), and measured habitat variables at fox and gray squirrel capture sites. Fox squirrel density estimates ranged from 12-19 squirrels/km2 among study areas. Fox squirrel capture sites had higher pine basal area, higher total basal area, higher herbaceous groundcover, and lower woody groundcover than other sites. Gray squirrel capture sites...

We monitored 13 (6 female, 7 male) adult bobcats (Lynx rufus) using radiotelemetry and examined seasonal activity patterns using 9,217 observations from August 1989 - August 1990. Female bobcats were active 49% and males were active 60% of the diel period. Mean percentage activity during winter of males (x = 71%,SE = 4.0%) was greater (P < 0.01) than that of females (x + 44%, SE + 5%). Bobcats exhibited greatest activity during crepuscular and nocturnal periods. We detected a less defined bimodal crepuscular activity than previous studies. High diurnal activity makes bobcats susceptible...

We developed a Geographical Information System (GIS) based habitat model for female bobcats (Lynx rufus) and subjected the model to internal-validation, cross-validation, and validation using independent data. The model predicted probability of an area being used by female bobcats increased (P <0.001) as slope and distance to mature pine stands increased. Probability of an area being used by female bobcats decreased (P <0.001) with increasing distance to sapling stands, mature hardwood stands, paved roads, maintenance roads, and creeks. Forest type (non-forested, pine dominated, or...

Habitat use occurs at several spatial scales; however, bobcat (Felis rufus) habitat use has not been investigated at multiple scales. Additionally, sex-specific differences in bobcat habitat use have been hypothesized but not tested. Therefore, we investigated habitat use of 30 bobcats (9 males, 21 females) from 1 January 1989 to 31 December 1993 on 2 study areas in east-central Mississippi. We investigated bobcat habitat use at 2 spatial scales: habitat use within the home range and habitat composition of the home range relative to habitat composition of the study area. We did not detect...

Sixteen adult bobcats (11 females, 5 males) (Felis rufus) were monitored using radio-telemetry from 1 January 1989-31 December 1992 in Mississippi to determine habitat components influencing core use area (CUA) location and size. Male bobcat CUA size (x = 26.5 km2, SE = 6.1) was larger (P = 0.047) than females (x = 11.8 km2, SE = 2.8). Habitat components of bobcat CUA's did not differ (P > 0.10) by sex. There was a higher (P < 0.01) proportion of pine plantations and agricultural habitats in CUA's than in random areas. There was a lower (P = 0.06) proportion of hardwood stands in CUA...

Fifteen bobcats (10 females, 5 males) were monitored using radio telemetry from 1 January 1989-31 December 1991 in east-central Mississippi. Male composite home ranges (HR) averaged 36.5 km2 (S.E. = 12.7) while female HR's averaged 20.6 km2 (S.C. = 7.7). Composite and seasonal HR sizes differed between sexes (P = 0.03 and P < 0.001, respectively). HR's were larger during the 1989 post-parturition (1 May-31 Aug) and fall (1 Sept-31 Dec) seasons than during most other seasons (P < 0.05). Intersexual HR overlap occurred during 5 of 9 seasons. Female-female HR overlap occurred during 3...
