dc.description.abstract | Habitat loss and degradation are thought to be the primary drivers of species
extirpations, but for many species we have little information regarding specific habitats that
influence occupancy. Snakes are of conservation concern throughout North America, but
effective management and conservation are hindered by a lack of basic natural history
information and the small number of large-scale studies designed to assess general population
trends. To address this information gap, we compiled detection/nondetection data for 13 large
terrestrial species from 449 traps located across the southeastern United States, and we
characterized the land cover surrounding each trap at multiple spatial scales (250-, 500-, and
1000-m buffers). We used occupancy modeling, while accounting for heterogeneity in
detection probability, to identify habitat variables that were influential in determining the
presence of a particular species. We evaluated 12 competing models for each species,
representing various hypotheses pertaining to important habitat features for terrestrial snakes.
Overall, considerable interspecific variation existed in important habitat variables and relevant
spatial scales. For example, kingsnakes (Lampropeltis getula) were negatively associated with
evergreen forests, whereas Louisiana pinesnake (Pituophis ruthveni) occupancy increased with
increasing coverage of this forest type. Some species were positively associated with grassland
and scrub/shrub (e.g., Slowinski’s cornsnake, Elaphe slowinskii ) whereas others, (e.g.,
copperhead, Agkistrodon contortrix, and eastern diamond-backed rattlesnake, Crotalus
adamanteus) were positively associated with forested habitats. Although the species that we
studied may persist in varied landscapes other than those we identified as important, our data
were collected in relatively undeveloped areas. Thus, our findings may be relevant when
generating conservation plans or restoration goals. Maintaining or restoring landscapes that
are most consistent with the ancestral habitat preferences of terrestrial snake assemblages will
require a diverse habitat matrix over large spatial scales. | en_US |
