Effects of experience and context on phototaxic behaviors of larval stream salamanders in the Upper Little Tennessee River basin
Desmognathus quadramaculatus larvae were captured from 2 locations in the Upper Little Tennessee River basin. Naïve individuals with respect to high-light environments were collected within the fully forested Ball Creek watershed at the Coweeta Hydrological Laboratory in Macon County, North Carolina. This watershed is a control basin that has been undisturbed since 1927. Individuals with experience in high-light environments, defined as habituated individuals, were collected from a first-order stream with less than 10% canopy cover located in Rabun County, Georgia. Salamanders were captured opportunistically using dipnets and cover object searches. Upon capture, salamanders were held individually in a cooler during transport where they were placed in containers with a paper towel cover object, native stream water, and kept in a temperature controlled room (15.5 C) with an indirect, natural photoperiod. Individual behaviors were tested within 48 hours of capture, and individuals were released at their capture location within one week.
Coweeta Synoptic Data from 49 sampling sites in the Upper Little Tennessee River Basin from 2009 to 2010 (mesoscale habitat data)
This data was generated as part of synoptic sampling conducted at the Coweeta LTER between June 2009 and May 2010. 49 wadeable streams with low levels of development were sampled throughout the Upper Little Tennessee River Basin in the Southern Appalachians. Effects of riparian vegetative conditions on a suite of channel morphological variables were investigated: active channel width, variability of width within a reach, large wood frequency, mesoscale habitat distributions, median particle size, and percent fines. Stream mesoscale habitat areas for each 150 m stream reach were recorded in this particular dataset. At each site, a uniform 150 meter section of stream was surveyed. Observers kept a running tally of the areas associated with various mesoscale habitat units including, cascades, riffles, pools, alcoves, pocket water, runs, glides, and obstructions.
Little Tennessee River Riparian Buffer change GIS data: 1998 - 2015
Using high resolution orthoimagery, riparian conditions between 1998 and 2015 were mapped and quantified in the rural upper Little Tennessee River basin in Macon County, North Carolina. Low elevation valley streams in residential areas were targeted, excluding stream segments on U.S. Forest Service (USFS) lands. Impoundments and streams within existing urban centers were also excluded from GIS analysis. Tributary streams were included if they were National Hydrography Dataset (NHD) mapped streams and if they met the study criteria, i.e. low-elevation residential valley streams outside existing urban areas and USFS lands. Due to the size of the watershed and time constraints, only the mainstem Little Tennessee and a portion of its tributary streams could be mapped. A total of 658 km (including both banks) of streams in the study area were mapped and classified. All classifications were made by one interpreter between June 2018 and August 2018. The GIS files are are in .zip archives labeled by imagery year (1998 and 2015). The 1998 GIS files are mislabeled '1999' which was corrected during analysis using R. The code used for analysis is provided in R markdown files.
Forest floor weights and Oe-Oa soil depths from 9 Hillslope Project sites in Macon County, North Carolina, within the Upper Little Tennessee River Basin
Forest floor samples were collected at 9 hillslope sites representing a gradient of development, including forested, valley agriculture, and mountain housing developments in Macon County, NC.

Hourly soil moisture, soil temperature, groundwater temperature, and groundwater stage height measurements from 9 Hillslope Study sites located in Macon County, North Carolina, within the Upper Little Tennessee River Basin
The Hillslope Study was established to directly link land use impacts to streamwater quality in the southern Appalachian Mountains. Nine sites were selected in the Little Tennessee River watershed in Macon County, NC, representing four land use types: forest, mountain development, traditional valley, and large river valley. At each of these sites, three subsurface flowpaths were identified, and four plots were established along the flowpath following the elevation gradient. At seven of the nine sites, the three lower elevation plots at one of the subsurface flowpaths had ground water wells installed in order to measure groundwater stage and temperature along an elevational gradient. Additional sensors were installed adjacent to the groundwater wells to measure soil moisture at 0-30 cm and 30-60 cm below the ground surface uphill and downhill of the well, and soil temperature at 5 cm below the ground surface. Measurements were taken every 60 seconds and output as hourly averages. Data were used as part of the Regional HydroEcological Simulation System (RHESSys) ecohydrologic model. Please see the accompanying well construction data for additional groundwater well information.
