Karst hydrogeology of Tuckaleechee Cove and the western Great Smoky Mountains, Tennessee and North Carolina
The geology of Great Smoky Mountains National Park (GRSM) in Tennessee and North Carolina is dominated by siliciclastics and metamorphic strata. However, in the western portion of GRSM, a series of carbonate fensters (windows) expose the Lower Ordovician–age section of the Knox Group, a series of dolomite and limestone units that are partially...
Miller, Benjamin; Bradley, Michael W.; Brown, Teresa L. An interim harvest strategy for Taiga Bean geese
In 2016 the AEWA European Goose Management International Working Group (EGM IWG) adopted document AEWA/EGM IWG 1.8 (Johnson et al. 2016), which contained initial elements of an Adaptive Harvest Management programme for Taiga Bean Geese. This report addresses a number of limitations with the population model presented in that document, and provides...
Johnson, Fred A.; Alhainen, Mikko; Fox, Anthony D.; Madsen, Jesper A multiscale natural community and species-level vulnerability assessment of the Gulf Coast, USA
Vulnerability assessments combine quantitative and qualitative evaluations of the exposure, sensitivity, and adaptive capacity of species or natural communities to current and future threats. When combined with the economic, ecological or evolutionary value of the species, vulnerability assessments quantify the relative risk to regional species...
Reece, Joshua S.; Watson, Amanda; Dalyander, Patricia (Soupy); Edwards, C.; Geselbracht, Laura; LaPeyre, Megan K.; Tirpak, Blair; John M. Tirpak; Woodrey, Mark Climate and plant controls on soil organic matter in coastal wetlands
Coastal wetlands are among the most productive and carbon‐rich ecosystems on Earth. Long‐term carbon storage in coastal wetlands occurs primarily belowground as soil organic matter (SOM). In addition to serving as a carbon sink, SOM influences wetland ecosystem structure, function, and stability. To anticipate and mitigate the effects of climate...
Osland, Michael J.; Gabler, Christopher A.; Grace, James B.; Day, Richard H.; McCoy, Meagan L.; McLeod, Jennie L.; From, Andrew S.; Enwright, Nicholas M.; Feher, Laura C.; Stagg, Camille L.; Hartley, Stephen B. A framework for identifying and characterising coral reef “oases” against a backdrop of degradation
Human activities have led to widespread ecological decline; however, the severity of degradation is spatially heterogeneous due to some locations resisting, escaping, or rebounding from disturbances.We developed a framework for identifying oases within coral reef regions using long‐term monitoring data. We calculated standardised estimates of...
Guest, James R.; Edmunds, Peter J.; Gates, Ruth D.; Kuffner, Ilsa B.; Andersson, Andreas J; Barnes, Brian B.; Chollett, Iliana; Courtney, Travis A.; Elahi, Robin; Gross, Kevin; Lenz, Elizabeth A.; Mitarai, Satoshi; Mumby, Peter J.; Nelson, Hannah R.; Parker, Britt A.; Putnam, Hollie M.; Rogers, Caroline S.; Toth, Lauren T. Book review: A new view on the species abundance distribution Stochastic communities: A mathematical theory of biodiversity
The sampled relative abundances of species of a taxonomic group, whether birds, trees, or moths, in a natural community at a particular place vary in a way that suggests a consistent underlying pattern, referred to as the species abundance distribution (SAD). Preston [1] conjectured that the numbers of species, plotted as a histogram of...
DeAngelis, Donald L. Variation in home range size and patterns in adult female American crocodiles Crocodylus acutus
The American crocodile Crocodylus acutus is a threatened species that uses relatively deep, open-water habitats with low salinity. Adult female American crocodiles nest on sandy coastal beaches, islands or human-made berms, assist in the hatching process, and can travel long distances to nesting habitat. We satellite-tracked 15 adult...
Hart, Kristen M.; Beauchamp, Jeffrey S.; Cherkiss, Michael S.; Mazzotti, Frank Flooding alters plant-mediated carbon cycling independently of elevated atmospheric CO2 concentrations
Plant‐mediated processes determine carbon (C) cycling and storage in many ecosystems; how plant‐associated processes may be altered by climate‐induced changes in environmental drivers is therefore an essential question for understanding global C cycling. In this study, we hypothesize that environmental alterations associated with near‐term climate...
Jones, Scott F.; Stagg, Camille L.; Krauss, Ken W.; Hester, Mark W. Quantifying relative importance: Computing standardized effects in models with binary outcomes
Scientists commonly ask questions about the relative importances of processes, and then turn to statistical models for answers. Standardized coefficients are typically used in such situations, with the goal being to compare effects on a common scale. Traditional approaches to obtaining standardized coefficients were developed with idealized...
Grace, James B.; Johnson, Darren; Lefcheck, Jonathan S.; Byrnes, Jarrett E.K. Coastal wetland adaptation to sea level rise: Quantifying potential for landward migration and coastal squeeze
Coastal wetland ecosystems are expected to migrate landwards in response to rising seas. However, due to differences in topography and coastal urbanization, estuaries vary in their ability to accommodate migration. Low‐lying urban areas can constrain migration and lead to wetland loss (i.e. coastal squeeze), especially where existing wetlands...
Borchert, Sinéad M.; Osland, Michael J.; Enwright, Nicholas M.; Griffith, Kereen Cumulative spring discharge and survey effort influence occupancy and detection of a threatened freshwater mussel, the Suwannee Moccasinshell
Freshwater mussels (Unionidae) are among the most imperiled groups of organisms in the world, and the lack of information regarding species distributions, life-history characteristics, and ecological and biological requirements may limit the protection of remaining mussel populations. We examined the influence of hydrologic factors on the...
Holcomb, Jordan M.; Shea, Colin P.; Johnson, Nathan A. President elect's message
The first morning home the day after I became president of SWS at the annual meeting in Denver, I note the wilting of my garden and the grumpiness of my cats as the dawn of my new reality. The extra hours that I will spend as president of SWS will manifest itself as more cat and garden unhappiness as travel and responsibilities grow. The cats...

Tearcoat Branch at I-95, near Manning (021355015)
We have installed a webcam at Tearcoat Branch at I-95, near Manning to allow you to view (in real time) the current river-stage conditions.
During periods of flooding, the South Atlantic Water Science Center will take control of the camera.
Camera is sponsored by the SC Department of Transportation.
Daylight and fluorescent images of a Montastrea caverno
Daylight and fluorescent images of a Montastrea cavernosa coral colony growing on the seawall at Ft. Jefferson, Dry Tortugas National Park. The brownish color of the coral in daylight is largely attributable to chlorophyll contained within the symbiotic algae harbored by the coral. The fluorescent image was taken at night using blue LED lights to stimulate

Aerial View of Faka Union Canal, Florida
This aerial view shows how Faka Union Canal (visible as a straight channel of water) connects the coastal environment, where manatees feed, to freshwater inlets. The Ten Thousand Islands region in the foreground supports sea grass beds where manatees feed. During cold winter months, manatees can swim up Faka Union Canal to a series of residential canals, where the unique
