Sinkholes and Springs of the Ozark Physiographic Province, northern Arkansas, from Topographic Maps

Noel Turner
Springs and sinkholes in the Ozark Plateaus Physiographic Province (Ozarks) in Arkansas were digitized from 1:24,000 scale topographic maps to produce a digital dataset of karst features. Karst landscapes generally are created from bedrock dissolution that results in distinctive landforms, including sinkholes, springs, caves, and sinking streams, and a high degree of interaction between surface water and groundwater. The dataset can be used to better understand groundwater flow in the karst landscape of the Arkansas...

Sediment-quality and water-toxicity data from 10 sites on the Westside Creeks and San Antonio River, San Antonio, Texas, 2014

Sediment samples and samples for water-toxicity testing were collected during 2014 from several streams in San Antonio, Texas known locally as the Westside creeks (Alazn, Apache, Martnez, and San Pedro Creeks) and from the San Antonio River. Samples were collected once during base-flow and again after periods of storm-water runoff (post-storm conditions) to determine baseline sediment- and water-quality conditions. Streambed-sediment samples were analyzed for selected constituents, including trace elements and organic contaminants such as pesticides,...

GIS data for predicting the occurrence of cave-inhabiting fauna based on features of the Earth surface environment in the Appalachian Landscape Conservation Cooperative (LCC) Region

Mary C. Christman, Daniel H. Doctor, Matthew L. Niemiller, David J. Weary, John A. Young, Kirk S. Zigler & David C. Culver
Cave-limited species display patchy and restricted distributions, but are challenging to study in situ because of the difficulty of sampling. It is often unclear whether the observed distribution is a sampling artifact or a true restriction in range. Further, the drivers of the distribution could be local environmental conditions, such as cave humidity, or they could be associated with surface features that are surrogates for cave conditions. If surface features can be used to predict...

Walrus used and available resource units for northeast Chukchi Sea, 2008-2012

William S Beatty, Chadwick V Jay, Anthony S Fischbach, J.M. Grebmeier, Rebecca L Taylor, A.L. Blanchard & S.C. Jewett
Sea ice loss represents a stressor to the Pacific walrus, which feeds on benthic macroinvertebrates in the Bering and Chukchi seas. However, no studies have examined the effects of sea ice on foraging walrus space use patterns. Thus, we examined walrus foraging resource selection as a function of proximity to resting substrates and prey biomass with a matched use-availability design. We quantified biomass of 17 benthic taxa, which included amphipods, bivalves, polychaete, sand dollars, tunicates,...

Effects of carbon dioxide on juveniles of the freshwater mussel Lampsilis siliquoidea (Unionidae).

Diane L Waller
Carbon dioxide has shown promise as a tool to control movements of invasive Asian carps. We evaluated lethal and sublethal responses of juvenile fat mucket (Lampsilis siliquoidea) mussels to carbon dioxide concentrations (43�269 mg/L, mean concentration) that are effective for deterring carp movement. The 28-d LC50 value (lethal concentration to 50% of the mussels) was 87.0 mg/L (95% confidence interval, CI 78.4�95.9) and at 16-d post-exposure was 76.0 mg/L (95% CI 62.9�90.3). A proportional hazards...

FishVis, predicted occurrence and vulnerability for 13 fish species for current (1961 - 1990) and future (2046 - 2100) climate conditions in Great Lakes streams.

Jana S. Stewart, Shawn A. Covert, Damon Krueger, Michael T. Slattery, Daniel J Wieferich, Stephen M Westenbroek, Dana M. Infante, & John D. Lyons
Climate change is expected to alter the distributions and community composition of stream fishes in the Great Lakes region in the 21st century, in part as a result of altered hydrological systems (stream temperature, streamflow, and habitat). Resource managers need information and tools to understand where fish species and stream habitats are expected to change under future conditions. Fish sample collections and environmental variables from multiple sources across the United States Great Lakes Basin were...
