This SSP project resulted in two publications Two New Sculpins of the Genus Cottus (Teleostei: Cottidae) from Rivers of Eastern North America David A. Neely, James D. Williams, and Richard L. Mayden Copeia 2007 2007:3, 641-655 Two new species of freshwater sculpins are herein described from the Gulf Slope of the southeastern United States. The Tallapoosa Sculpin, Cottus tallapoosae, is restricted to the Tallapoosa River drainage, a tributary to the Mobile Basin, above the Fall Line in Alabama and Georgia, while the Chattahoochee Sculpin, Cottus chattahoochee, is restricted to the Chattahoochee River drainage, a tributary to the Apalachicola River, above the Fall Line in Georgia. Both differ from other North American...

This QR project provided support to help complete the work for a manuscript: Reconstructing Vegetation Response to Altered Hydrology and its Use for Restoration, Arthur R. Marshall Loxahatchee National Wildlife Refuge, Florida that was published in Wetlands. We present reconstructed hydrologic and vegetation trends of the last three centuries across the Arthur R. Marshall Loxahatchee National Wildlife Refuge, Florida in order to understand the effects of 20th century water management. We analyzed pollen assemblages from cores at marsh sites along three transects to document vegetation and infer hydroperiod and water depth both before and after human alteration of Everglades hydrology. In the northern and central...

This SSP project produced a final report on abundance of mallards in the MAV. In 1995, breeding habitat conditions improved and populations of most prairie-nesting ducks increased. Also in 1995, the Adaptive Harvest Management (AHM) program was initiated to select hunting regulations that maximized long-term harvest of mid-continent mallards. Generally, AHM has provided liberal harvests and hunting opportunity. The Lower Mississippi Valley (LMV) Joint Venture partnership has acquired new wildlife management areas and encouraged more private landowners to flood croplands to accommodate increased waterfowl populations envisioned in the North American Waterfowl Management Plan (NAWMP). Together, these developments...

This report presents findings of research accomplished with funding through the USGS “Species at Risk” and 'FWS Critical Needs' programs, to address the status and distribution of 'at-risk' aquatic species in the upper Tallapoosa River system in Georgia and Alabama. The upper Tallapoosa river system contains at least five endemic fishes ( Cyprinella gibbsi, Etheostoma chuckwachatte, E. tallapoosae, Percina sp. and Cottus sp.), two endemic crayfishes ( Cambarus englishi, C. halli), an endemic mussel, Quadrula archeri and an endemic freshwater snail ( Elimia flava). A sixth fish species, Fundulus bifax, is nearly restricted to the Tallapoosa River system, having a single known locale outside of the Tallapoosa. In...

This SSP project resulted in a final report that addressed two objectives: (1) to develop nonbiased methods for estimating stream-fish distribution and abundance and (2) to develop a prioritized GIS inventory of manmade culverts, dams, and other structures impeding fish passage in priority sub-watersheds of the Upper Coosa Basin. These data were collected to assist the Service and Partners in better protecting and recovering the six listed fish, 6 listed mussels, and other rare species in the Upper Coosa Basin. The report included a publication: Price, A.L. and J.T. Peterson. 2010. Estimation and Modeling of Electrofishing Capture Efficiency for Fishes in Wadeable Warmwater Streams. NOrth American Journal of...

This SSP project resulted in a final report and one publication. Toxicity tests were conducted at the U.S. Geological Survey Columbia Environmental Research Center (CERC), Columbia, Missouri to determine the effects of sediments from impacted (historic coal mining or gas well activities) and un-impacted (these activities did not occur) river sites on growth and mortality of 2 mo old rainbow mussels (Villosa iris). Tissue from surviving juveniles from one replicate (n = 1) of each of the sediment exposures were histologically processed and qualitatively evaluated to determine sub-lethal effects on their organ and visceral tissues. Many tissues were improperly embedded, but re-embedding allowed most tissues to be...
This QR project contributed information to the MAPS (Monitoring avian production and survivorship) program.

After being nearly driven to extinction by the combination of human persecution, human-caused habitat change, and subsequent hybridization with coyotes, red wolves (Canis rufus) were rescued from extinction by the establishment of a captive breeding program in 1973. In 1987, red wolves were first released into a coyote-free (Canis latrans) area in northeastern North Carolina. But by the early 1990’s coyotes began colonizing the area, and pairings between red wolves and coyotes were first detected in 1993. In 2000, a program to contain hybridization and introgression by sterilizing coyotes and removing hybrids began. Genetic assignment tests were used to determine which canids were red wolves, hybrids, and coyotes....
