Freshwater mussels native to the Southeastern and Mid-Atlantic regions of the United States are highly imperiled due to habitat alteration and destruction, pollution and poor water quality, and the introduction of aquatic invasive species. Even greater risks to these species stem from the stresses associated with climate change-induced sea level rise, such as changes in salinity, water temperature, and stream flow. This research investigates the potential vulnerability and adaptation of native freshwater mussels associated with changes in salinity. This dataset contains raw survival and LC50 data generated when conducting acute toxicity tests on three species of freshwater mussels, exposing them to a synthetic sea...
Breeding common loons were obtained for the movement and foraging pattern study from lakes in central and northern Minnesota and Wisconsin, and the Upper Peninsula of Michigan. Both adults of a territorial pair were fitted with archival geolocator tags (Model LAT 2500; 34.6 x 8.3 mm, 4.4 g; Lotek Wireless Inc.). A combination of adhesive and plastic cable ties were used to affix the geolocator tag to a modified lock-on aluminum leg band. Tags were programmed to collect daily location estimates for up to two years, tag temperature (0.02 oC accuracy, ≤ 0.05 oC resolution) at 30-min intervals, and pressure data (±1% accuracy, 0.05% resolution) at 20-sec intervals during daylight hours to document foraging patterns...
The data were generated as part of a study to determine if buccal (oral) swabs could be used to obtain genetic material from Red-Cockaded Woodpecker chicks. Different swab types were investigated to determine if any specific type gave the highest DNA yields.

Open canopy conditions in southeastern pine (Pinus spp.) forests were historically maintained by frequent fire and other disturbances, without which midstory hardwoods create closed canopy conditions limiting value of pine stands for many endemic, disturbance-adapted species. Intensively managed pine forests, which comprise 19% of forests in the southeastern U.S., can emulate historical open pine conditions, providing appropriate vegetation structure and composition for many endemic species. However, exact mechanisms for producing and maintaining open pine conditions and subsequent effects on biodiversity have not been examined across regions and stand ages. To better inform managers about options for providing...

This dataset contains hourly average groundwater level time-series for 19 monitoring wells at the Panola Mountain Research Watershed (PMRW) from January 2001 to October 2002. The data was used in a hydrologic modeling study to test a model formulation that allowed for bi-direction fluxes between groundwater and surface water in a bucket type hydrologic model. Some wells had missing data so record lengths were not equal. The water level data were quality controlled; unexplained peaks and shifts were removed, and these periods were indicated as having no data. The modeling study used average water level data from the riparian area and from the entire catchment for calibration. Riparian groundwater levels were calculated...
These data represent time-series of water table depth from nine monitoring wells, soil moisture from three depths at a single monitoring location, and meteorological data from a weather station at the Panola Mountain Research Watershed (PMRW) in Rockdale County Georgia. Water-level data were logged at a 5 minute interval. In total, the data span from April 2017 to April 2020 but some wells did not get instrumented with pressure transducers until May 2018 so there are some minor differences in record length. Soil moisture spans from April 2017 to October 2019 and data is presented as hourly average volumetric water content at each depth. Meteorological data spans from April 2017 to October 2019 and is presented as...
