adult bobcat lynx rufus Habitat Selection in a longleaf pine savanna
Ecological processes, 2018Co-Authors: Andrew R. Little, Michael J Chamberlain, Mike L Conner, Nathan P. Nibbelink, Robert J WarrenAbstract:Pine savannas are primarily managed with frequent prescribed fire (≤ 3 years) to promote diversity of flora and fauna, and to maintain open, park-like conditions needed by species such as the endangered red-cockaded woodpecker (Picoides borealis). However, a knowledge gap exists in our understanding of bobcat (Lynx rufus) Habitat Selection in longleaf pine savannas and research is warranted to direct our future management decisions. We examined bobcat Habitat Selection in a pine savanna managed with frequent fires at two spatial scales (i.e., study area boundary [hereafter, landscape scale]) and annual area of use [95% kernel density; local scale]), and assessed effects of prescribed fire on bobcat Habitat Selection. Specifically, we monitored 45 bobcats (16 males and 29 females) during 2001–2007. We found differential Habitat Selection by sex. At the landscape scale, female bobcats were closer to mixed pine-hardwoods, young pine, and secondary roads, but farther from mature pine and hardwoods stands relative to males. We found no difference in Selection of agriculture, shrub-scrub, and primary roads between sexes. At the annual area of use scale, female bobcats were closer to secondary roads, but farther from agriculture and shrub-scrub relative to males. We found no difference in Selection of mature pine, mixed pine-hardwoods, hardwoods, young pine, and primary roads between sexes. Bobcats primarily selected for stands burned ≤ 1.1 years post-fire. Our results show that bobcats exploit a broad range of Habitat types in pine landscapes managed with frequent fire and commonly use recently burned stands (≤ 1.1 year post-fire), suggesting prey in many areas of this system are at risk of bobcat predation. Additionally, we suggest land managers consider scale of Selection by bobcats when developing Habitat management strategies.

Habitat Selection and diurnal refugia of gray foxes in southwestern Georgia, USA
2017Co-Authors: Nicholas R. Deuel, Michael J Chamberlain, Mike L Conner, Karl V. Miller, Michael J. Cherry, Larry V. TannenbaumAbstract:Understanding Habitat Selection of gray foxes (Urocyon cinereoargenteus) is essential to evaluate their potential response to changes in land use and predator communities. Few studies have evaluated temporal Habitat Selection or explicitly identified Habitats used by gray foxes for diurnal refugia. We used GPS collars to obtain location data for 34 gray foxes (20 males and 14 females) from February 2014 to December 2015 to evaluate temporal (seasonal and diel) Habitat Selection and Selection of diurnal refugia in southwestern Georgia, USA. We analyzed Habitat Selection at 2 levels, Selection of a core area within the home range and Selection of locations within the home range. Habitat Selection was non-random (P < 0.001) but consistent among seasons, between day and night, and between sexes (P > 0.05). Hardwoods, human use (i.e., areas associated with regular human activity such as buildings, lawns, parking areas, etc.), and roads were selected (P < 0.05), whereas pine dominated stands were used randomly (P > 0.05). Selection of Habitats for diurnal refugia did not vary seasonally or by sex (P > 0.05), with foxes selecting (P < 0.05) areas near hardwood forests, roads, agriculture, human use, pastures/food plots, and shrub scrub Habitats. Gray foxes were observed on the ground while resting, and we found no evidence of gray foxes diurnally resting in trees. Our results suggest that on our study area, gray foxes are an edge species that prefer forests with a hardwood component in areas near human use and roads.

space use and Habitat Selection by resident and transient red wolves canis rufus
PLOS ONE, 2016Co-Authors: Joseph W Hinton, Christine Proctor, Marcella J Kelly, Frank T Van Manen, Michael R Vaughan, Michael J ChamberlainAbstract:Recovery of large carnivores remains a challenge because complex spatial dynamics that facilitate population persistence are poorly understood. In particular, recovery of the critically endangered red wolf (Canis rufus) has been challenging because of its vulnerability to extinction via human-caused mortality and hybridization with coyotes (Canis latrans). Therefore, understanding red wolf space use and Habitat Selection is important to assist recovery because key aspects of wolf ecology such as interspecific competition, foraging, and Habitat Selection are well-known to influence population dynamics and persistence. During 2009–2011, we used global positioning system (GPS) radio-telemetry to quantify space use and 3rd-order Habitat Selection for resident and transient red wolves on the Albemarle Peninsula of eastern North Carolina. The Albemarle Peninsula was a predominantly agricultural landscape in which red wolves maintained spatially stable home ranges that varied between 25 km2 and 190 km2. Conversely, transient red wolves did not maintain home ranges and traversed areas between 122 km2 and 681 km2. Space use by transient red wolves was not spatially stable and exhibited shifting patterns until residency was achieved by individual wolves. Habitat Selection was similar between resident and transient red wolves in which agricultural Habitats were selected over forested Habitats. However, transients showed stronger Selection for edges and roads than resident red wolves. Behaviors of transient wolves are rarely reported in studies of space use and Habitat Selection because of technological limitations to observed extensive space use and because they do not contribute reproductively to populations. Transients in our study comprised displaced red wolves and younger dispersers that competed for limited space and mating opportunities. Therefore, our results suggest that transiency is likely an important life-history strategy for red wolves that facilitates metapopulation dynamics through short- and long-distance movements and eventual replacement of breeding residents lost to mortality.

space use and Habitat Selection by resident and transient coyotes canis latrans
PLOS ONE, 2015Co-Authors: Joseph W Hinton, Frank T Van Manen, Michael J ChamberlainAbstract:Little information exists on coyote (Canis latrans) space use and Habitat Selection in the southeastern United States and most studies conducted in the Southeast have been carried out within small study areas (e.g., ≤1,000 km2). Therefore, studying the placement, size, and Habitat composition of coyote home ranges over broad geographic areas could provide relevant insights regarding how coyote populations adjust to regionally varying ecological conditions. Despite an increasing number of studies of coyote ecology, few studies have assessed the role of transiency as a life-history strategy among coyotes. During 2009–2011, we used GPS radio-telemetry to study coyote space use and Habitat Selection on the Albemarle Peninsula of northeastern North Carolina. We quantified space use and 2nd- and 3rd-order Habitat Selection for resident and transient coyotes to describe space use patterns in a predominantly agricultural landscape. The upper limit of coyote home-range size was approximately 47 km2 and coyotes exhibiting shifting patterns of space use of areas >65 km2 were transients. Transients exhibited localized space use patterns for short durations prior to establishing home ranges, which we defined as “biding” areas. Resident and transient coyotes demonstrated similar Habitat Selection, notably Selection of agricultural over forested Habitats. However, transients exhibited stronger Selection for roads than resident coyotes. Although transient coyotes are less likely to contribute reproductively to their population, transiency may be an important life history trait that facilitates metapopulation dynamics through dispersal and the eventual replacement of breeding residents lost to mortality.

space use movements and Habitat Selection of adult bobcats lynx rufus in central mississippi
American Midland Naturalist, 2003Co-Authors: Michael J Chamberlain, Bruce D. Leopold, Mike L ConnerAbstract:Abstract Many factors influence bobcat (Lynx rufus) space use, movements and Habitat Selection, including prey distribution and density, season, breeding behaviors and intraspecific relationships. Knowledge of ranging behaviors and Habitat Selection is required to understand population dynamics and ecology of bobcats within temperate ecosystems. We radio-monitored 58 adult bobcats from 1989–1997 in central Mississippi. Males maintained larger home ranges and core areas than females, but sizes of these areas did not vary seasonally. Male bobcats moved at greater rates than females and bobcats moved at greatest rates during nocturnal periods. Movement rates were greatest during winter. Habitat Selection at three spatial scales differed between genders and across seasons within gender. Our findings suggest that ≤8 y-old pine (Pinus spp.) Habitats are important to bobcats, particularly females, as these Habitats were selected by females at all spatial scales. However, our data also indicate that mature (>30 y...
