| Popis: | Small headwater streams are a common feature of many forested landscapes, and their integrity is considered critical to the maintenance of water quality and biodiversity within broader drainage networks. Although riparian buffer zones are often established to limit disturbance to stream ecosystems from human land use, various buffer zone management strategies may provide effective protection to certain aquatic or semi-aquatic species while only encompassing a portion of core habitat for other species. Thus, an improved understanding of species distributions within riparian forests can be useful for predicting the overall effectiveness of various forest management practices. In this study, we conducted area-constrained surveys for salamanders at 16 plots within terrestrial habitat. We then employed an information-theoretic (AIC) approach to model selection to quantify the distribution of aquatic-breeding Ocoee Salamanders, Desmognathus ocoee, within terrestrial habitat as a function of stream length, width... |
