“…We further documented that bobcats select forest edge, wetland edge, and areas with high stream density during movement. In spite of our low sample size of collared bobcats, combined with the requirement that consecutive GPS locations exceed 60 m to constitute movement, these results are fairly consistent with other studies on bobcats (Woolf and Nielsen 2002;Chamberlain et al 2003;Hansen 2007;Litvaitis et al 2015;Reed et al 2016). Preferences for forest and scrub habitats are consistent with high prey densities and this species' role as an obligate carnivore, which may explain why movement paths were selected in these areas (Hansen 2007).…”

“…Bobcats move long distances within their home ranges and travel mostly by night, with males traveling farther and faster than females (Chamberlain et al 2003). Bobcats use a variety of land cover types for travel, including stream valleys and associated ridgelines (Woolf and Nielsen 2002), thick understories (Litvaitis et al 1986), and rocky ledges (Anderson 1990;Hansen 2007).…”

Context The analysis of individual movement choices can be used to better understand populationlevel resource selection and inform management. Objectives We investigated movements and habitat selection of 13 bobcats in Vermont, USA, under the assumption individuals makes choices based upon their current location. Results were used to identify ''movement-defined'' corridors.Methods We used GPS-collars and GIS to estimate bobcat movement paths, and extracted statistics on land cover proportions, topography, fine-scale vegetation, roads, and streams within ''used'' and ''available'' space surrounding each movement path. Compositional analyses were used to determine habitat preferences with respect to landcover and topography; ratio tests were used to determine if used versus available ratios for vegetation, roads, and streams 123Landscape Ecol (2018) 33:1301-1318 https://doi.org/10.1007/s10980-018-0654-8 differed from 1. Results were used to create travel cost maps, a primary input for corridor analysis. Results Forested and scrub-rock land cover were most preferred for movement, while developed land cover was least preferred. Preference depended on the composition of the ''available'' landscape: Bobcats moved [ 3 times more quickly through forest and scrub-rock habitat when these habitats were surrounded by agriculture or development than when the available buffer was similarly composed. Overall, forest edge, wetland edge and higher stream densities were selected, while deep forest core and high road densities were not selected. Landscape-scale connectivity maps differed depending on whether habitat suitability, preference, or selection informed the travel cost map. Conclusions Both local and landscape scale land cover characteristics affect habitat preferences and travel speed of bobcats, which in turn can inform management and conservation activities.

The increasing use of the landscape by humans has led to important diminutions of natural surfaces. The remaining patches of wild habitat are small and isolated from each other among a matrix of inhospitable land-uses. This habitat fragmentation, by disabling population movements and stopping their spread to new habitats, is a major threat to the survival of numerous plant and animal species. We developed a general model, adaptable for specific species, capable of identifying suitable habitat patches within fragmented landscapes and investigating the capacity of populations to move between these patches. This approach combines GIS analysis of a landscape, with spatial dynamic modeling. Suitable habitat is identified using a threshold area to perimeter ratio. Potential movement pathways of species between habitat patches are modeled using a cellular automaton. Habitat connectivity is estimated by overlaying habitat patches with movement pathways. The maximum potential population is calculated within and between connected habitat patches and potential risk of inbreeding within meta-populations is considered. The model was tested on a sample map and applied to scenario maps of predicted land-use change in the Peoria Tri-county region (IL). It (1) showed area of natural area alone was insufficient to estimate the consequences on animal populations; (2) underscored the necessity to use approaches investigating the effect of land-use change spatially through the landscape and the importance of considering species-specific life history characteristics; and (3) highlighted the model's potential utility as an indicator of species likelihood to be affected negatively by land-use scenarios and therefore requiring detailed investigation.

“…I used compositional analysis methods (as in Chamberlain et al 2003 andTucker et al 2008) to estimate the ratio of used to available habitat for each collared bobcat at three levels: home range to available habitat, core to available, and core to home range. I used a paired t-test to test whether the percent of avocado orchard in the used and available habitats differed.…”
