Louisiana is the leading state in number of river otters (Lontra canadensis) used in reintroduction programs in other states and in the production of pelts. However, habitat loss and degradation have prompted concern about the status of otter populations. We analyzed harvesting records maintained by the Louisiana Department of Wildlife and Fisheries during 1983-2001 to identify spatial and temporal trends in otter harvesting activity. To summarize temporal trends, we estimated mean number of otters harvested and trappers, correlation coefficients for number otters trapped and number of...

Black bear (Ursus americanus) conservation and restoration in the southeastern United States have become conservation priorities in the past decade. The release of black bears into portions of their former range has been proposed in some states and initiated in others to re-colonize available habitats. To coincide with restoration of the federally threatened Louisiana black bear (U. a. luteolus) to public lands, we conducted hunter surveys (N = 518) at release sites and proposed release sites. Although public meetings were held with the region where bear restoration was proposed, < 60%...

Kentucky-31 tall fescue (Festuca arundicacea) was a common planting established on Conservation Reserve Program (CRP) fields throughout the southeastern United States during the late 1980s and 1990s. Fescue-dominated grassland communities on CRP fields offer poor quality nesting, brood-rearing, and foraging habitat for northern bobwhite (Colinus virginianus) because of dense vegetation, high litter cover, low bare ground, and low plant diversity. Herbicide applications have been shown to reduce fescue and release early successional plant communities, and therefore may enhance bobwhite...

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...

Raccoons (Procyon lotor) are important furbearers that generate considerable income and recreation across the southeastern United States. Growing concerns about impacts of raccoons on wildlife populations necessitates sound information on raccoon behavior and population dynamics. Forest management has changed throughout the southeastern United States due to increased demands for wood fiber and changing land-use objectives on public lands. However, little research has examined potential influences of forest management strategies on raccoon ranging behavior, particularly within intensively...

Squirrels (Sciuris spp.) are important game species; however, it is believed that southern fox squirrel (S. niger) populations in many regions are declining. Changes in forest management practices may have reduced habitat availability and diversity, thereby contributing to declining population trends. However, relationships among forest management practices, active management of wildlife habitats, and wildlife populations requires an understanding of relationships among forest communities and wildlife populations. We used linear regression to build predictive models of gray squirrel (S....

Effect of exploitation on sympatric southern squirrel populations has not been documented. Additionally, opportunities to study effects of harvest on unexploited populations are rare. Consequently, we investigated the effect of exploitation on a previously unharvested population of fox (Sciurus niger) and gray squirrels (S. carolinensis) on Twin Oaks Wildlife Management Area, Mississippi, from 1993-1998. We annually collected age, body morphometrics, color, sex, and species composition of harvested squirrels at voluntary check stations. A population decrease was documented for both species...

Bobcats (Lynx rufus) and coyotes (Canis latrans) are sympatric in many areas; however, this sympatry has evolved relatively recently in the southeastern United States with coyote range expansion. Where the 2 species are sympatric, habitat selection and diets of bobcats and coyotes may overlap. Knowledge of seasonal variation in prey selection is required to assess interspecific competition and understand factors facilitating coexistence between sympatric species, yet long-term (>5 years) information on sympatric diets is unavailable. We collected and analyzed 1,183 scats (591 bobcat,...

Scent-station surveys have been used to examine trends in felid and canid abundance throughout the Southeast. Scent station methods have been developed on the presumption that canids rely on olfactory stimuli and that bobcats (Lynx rufus) rely on sight and auditory stimuli. No studies have quantified the effects of various olfactory, auditory, and visual stimuli on scent-station visitation by bobcats and canids; however, such information could improve the effectiveness and ability of scent-station surveys. We established scent stations and track transects in intensively managed pine...

We radio-monitored 35 wild turkey (Meleagris gallopavo) hens during prenesting and nesting periods in central Mississippi, 1996-1997. Comparing microhabitat variables associated with prenesting areas (N = 35) and nest sites (N = 22) with random sites indicated that groundstory conditions, including grass and woody growth, were related to hen selection of both prenesting and nesting sites. Distance to nearest road, vertical vegetative cover, and basal area were not related to nest site location (P > 0.05). We recommend managers maintain habitats with abundant grasses within landscapes...
