Host susceptibility to snake fungal disease is highly dispersed across phylogenetic and functional trait space
Frank T. Burbrink, Jeffrey M. Lorch, Karen R. Lips
2017, Science Advances (3)
Emerging infectious diseases (EIDs) reduce host population sizes, cause extinction, disassemble communities, and have indirect negative effects on human well-being. Fungal EIDs have reduced population abundances in amphibians and bats across many species over large areas. The recent emergence of snake fungal disease (SFD) may have caused declines in some...
A general modeling framework for describing spatially structured population dynamics
Christine Sample, John Fryxell, Joanna A. Bieri, Paula Federico, Julia Earl, Ruscena Wiederholt, Brady J. Mattsson, Tyler Flockhart, Sam Nicol, James E. Diffendorfer, Wayne E. Thogmartin, Richard A. Erickson, D. Ryan Norris
2017, Ecology and Evolution (8) 493-508
Variation in movement across time and space fundamentally shapes the abundance and distribution of populations. Although a variety of approaches model structured population dynamics, they are limited to specific types of spatially structured populations and lack a unifying framework. Here, we propose a unified network-based framework sufficiently novel in its...
Operationalizing the telecoupling framework for migratory species using the spatial subsidies approach to examine ecosystem services provided by Mexican free-tailed bats
Laura Lopez Hoffman, James E. Diffendorfer, Ruscena Widerholt, Wayne E. Thogmartin, Gary McCraken, Rodrigo Medellin, Kenneth J. Bagstad, Amy Russell, Darius J. Semmens
2017, Ecology and Society (22)
Drivers of environmental change in one location can have profound effects on ecosystem services and human well-being in distant locations, often across international borders. The telecoupling provides a conceptual framework for describing these interactions—for example, locations can be defined as sending areas (sources of flows of ecosystem services, energy, or...
Granular flows at recurring slope lineae on Mars indicate a limited role for liquid water
Colin M. Dundas, Alfred S. McEwen, Matthew Chojnacki, Moses P. Milazzo, Shane Byrne, Jim McElwaine, Anna Urso
2017, Nature Geoscience (10) 903-907
Recent liquid water flow on Mars has been proposed based on geomorphological features, such as gullies. Recurring slope lineae — seasonal flows that are darker than their surroundings — are candidate locations for seeping liquid water on Mars today, but their formation mechanism remains unclear. Topographical analysis shows that the...

In commemoration of the 100th anniversary of the British Ecological Society, Sutherland et al. (2013) identified 100 questions of fundamental significance in “pure” (i.e., not applied) ecology. A somewhat unexpected outcome of these authors’ exercise was the realization that, after 100 years of comprehensive, intensive scientific research, there remained “profound...
Linking fluvial and aeolian morphodynamics in the Grand Canyon, USA
Alan Kasprak, Sara G. Bangen, Daniel D. Buscombe, Joshua Caster, Amy E. East, Paul E. Grams, Joel B. Sankey
2017, Conference Paper, RCEM 2017 - Back to Italy: The 10th Symposium on River, Coastal and Estuarine Morphodynamics
In river valleys, fluvial and upland landscapes are intrinsically linked through sediment exchange between the active channel, near-channel fluvial deposits, and higher elevation upland deposits. During floods, sediment is transferred from channels to low-elevation nearchannel deposits [Schmidt and Rubin, 1995]. Particularly in dryland river valleys, subsequent aeolian reworking of these...

Christie Hegermiller, Ana C. Rueda, Li H. Erikson, Patrick L. Barnard, J.A.A. Antolinez, Fernando J. Mendez
2017, Geophysical Research Letters (44) 12315-12323
Coastal hazards emerge from the combined effect of wave conditions and sea level anomalies associated with storms or low-frequency atmosphere-ocean oscillations. Rigorous characterization of wave climate is limited by the availability of spectral wave observations, the computational cost of dynamical simulations, and the ability to link wave-generating atmospheric patterns with...

Alan G. Leach, David H. Ward, James S. Sedinger, Mark S. Lindberg, W. Sean Boyd, Jerry W. Hupp, Robert J. Ritchie
2017, Journal of Wildlife Management (81) 1210-1218
Since the mid 1990s, the number of black brant (Branta bernicla nigricans; brant) nests on the Yukon‐Kuskokwim Delta (YKD), Alaska, USA, the historically predominant breeding area of brant, has declined steadily. This has caused researchers and managers to question if arctic breeding populations can compensate for the reduction in brant...
Production and evaluation of YY-male Brook Trout to eradicate nonnative wild brook trout populations
Patrick Kennedy, Daniel J. Schill, Kevin A. Meyer, Matthew R. Campbell, Ninh V. Vu, Michael J. Hansen
2017, Conference Paper, Wild Trout Symposium XII—Science, Politics, and Wild Trout Management: Who’s Driving and Where Are We Going?
Nonnative Brook Trout Salvelinus fontinalis were introduced throughout western North America in the early 1900s, resulting in widespread self-sustaining populations that are difficult to eradicate and often threaten native salmonid populations. A novel approach for their eradication involves use of YY male (MYY) Brook Trout (created in the hatchery by...

The Southern Appalachian Brook Trout management conundrum: What should restoration look like in the 21st Century?
Matt A. Kulp, Shawna Mitchell, David C. Kazyak, Bernard R. Kuhajda, Jason Henegar, T. Casey Weathers, Anna George, Joshua R. Ennen, Tim King
2017, Conference Paper, Proceedings of the wild trout XII symposium
Brook Trout Salvelinus fontinalis in the southern Appalachian portion of their range have been isolated in remote headwater systems for millennia. Recent genetic investigations indicate extremely low allelic diversity, heterozygosity and effective population sizes in many streams. In populations restored using multiple source stocks, limited introgression has been observed despite...
