Michael R. Gatlin, James M. Long, Donald J. Turton
2015, Proceedings of the Oklahoma Academy of Science (95) 135-146
The natural flow regime is important for structuring streams and their resident ichthyofauna and alterations to this regime can have cascading consequences. We sought to determine if changes in hydrology could be attributed to changes in precipitation in a minimally altered watershed (Lee Creek). The stream flow regime was analyzed...

Daniel A. Cincotta, Stuart A. Welsh, Douglas P. Wegman, Thomas E. Oldham, Lara B. Hedrick
2015, Southeastern Naturalist (14) 297-313
The Blackwater River, a tributary of the upper Cheat River of the Monongahela River, hosts a modest fish fauna. This relatively low diversity of fish species is partly explained by its drainage history. The Blackwater was once part of the prehistoric, northeasterly flowing St. Lawrence River. During the Pleistocene Epoch,...

2015, Freshwater Science (34) 139-160
Groundwater–surface-water (GW-SW) interactions in streams are difficult to quantify because of heterogeneity in hydraulic and reactive processes across a range of spatial and temporal scales. The challenge of quantifying these interactions has led to the development of several techniques, from centimeter-scale probes to whole-system tracers, including chemical, thermal, and electrical...
Brittle Faults
Soumyajit Mukherjee
2015, Book chapter
Brittle shear zones/fault zones are usually defined by curved brittle P-planes bound by usually straight Y-planes. These shears may affect as a narrow zone within the rock bodies. Brittle sheared lenses of rocks vary in geometry, and the P-planes may curve only near the Y-planes. Fault gouge zones sometimes contain...

Henry M. Streby, Gunnar R. Kramer, Sean M. Peterson, Justin A. Lehman, David A. Buehler, David E. Andersen
2015, Current Biology (25) 98-102
Migration is a common behavior used by animals of many taxa to occupy different habitats during different periods. Migrant birds are categorized as either facultative (i.e., those that are forced to migrate by some proximal cue, often weather) or obligate (i.e., those that migrate on a regular cycle). During migration,...

Luke A. Groff, Aram J.K. Calhoun, Cynthia S. Loftin
2015, Herpetological Review (46) 234-234
Lithobates sylvaticus is the second most widely distributed anuran in North America (Martof and Humphries 1959. Am. Midl. Nat. 61:350–389), and its habitat use reflects the environmental variation that exists across its geographic range (Semlitsch et al. 2009. BioScience 59:853–862). Although L. sylvaticus post-breeding habitat selection has been described in...
Day-roost tree selection by northern long-eared bats—What do non-roost tree comparisons and one year of data really tell us?
Alexander Silvis, W. Mark Ford, Eric R. Britzke
2015, Global Ecology and Conservation (3) 756-763
Bat day-roost selection often is described through comparisons of day-roosts with randomly selected, and assumed unused, trees. Relatively few studies, however, look at patterns of multi-year selection or compare day-roosts used across years. We explored day-roost selection using 2 years of roost selection data for female northern long-eared bats (Myotis...
