Incidental captures of Eastern Spotted Skunk in a high-elevation Red Spruce forest in Virginia
Corinne A. Diggins, David S. Jachowski, Jay Martin, W. Mark Ford
2015, Northeastern Naturalist (22) N6-N10
Spilogale putorius (Eastern Spotted Skunk) is considered rare in the southern Appalachian Mountains and throughout much of its range. We report incidental captures of 6 Eastern Spotted Skunks in a high-elevation Picea rubens (Red Spruce) forest in southwestern Virginia during late February and March 2014. At 1520 m, these observations...
Accounting for multiple climate components when estimating climate change exposure and velocity
Christopher P. Nadeau, Angela K. Fuller
2015, Methods in Ecology and Evolution (6) 697-705
The effect of anthropogenic climate change on organisms will likely be related to climate change exposure and velocity at local and regional scales. However, common methods to estimate climate change exposure and velocity ignore important components of climate that are known to affect the ecology and evolution...
Variability and trends in global drought
Gregory J. McCabe, David M. Wolock
2015, Earth and Space Science (2) 223-228
Monthly precipitation (P) and potential evapotranspiration (PET) from the CRUTS3.1 data set are used to compute monthly P minus PET (PMPE) for the land areas of the globe. The percent of the global land area with annual sums of PMPE less than zero are used as an index of global drought (%drought)...
Reach-scale stream restoration in agricultural streams of southern Minnesota alters structural and functional responses of macroinvertebrates
Christine L. Dolph, Susan L. Eggert, Joe Magner, Leonard C. Ferrington Jr., Bruce C. Vondracek
2015, Freshwater Science (34) 535-546
Recent studies suggest that stream restoration at the reach scale may not increase stream biodiversity, raising concerns about the utility of this conservation practice. We examined whether reach-scale restoration in disturbed agricultural streams was associated with changes in macroinvertebrate community structure (total macroinvertebrate taxon richness, total macroinvertebrate density, Ephemeroptera, Plecoptera,...
Preserving geomorphic data records of flood disturbances
John A. Moody, Deborah A. Martin, Robert H. Meade
2015, GeoResJ (6) 164-174
No central database or repository is currently available in the USA to preserve long-term, spatially extensive records of fluvial geomorphic data or to provide future accessibility. Yet, because of their length and continuity these data are valuable for future research. Therefore, we built a public accessible website to preserve...
Biogeochemical aspects of uranium mineralization, mining, milling, and remediation
Kate M. Campbell, Tanya J. Gallegos, Edward R. Landa
2015, Applied Geochemistry (57) 206-235
Natural uranium (U) occurs as a mixture of three radioactive isotopes: 238U, 235U, and 234U. Only 235U is fissionable and makes up about 0.7% of natural U, while 238U is overwhelmingly the most abundant at greater than 99% of the total mass of U. Prior to the 1940s, U...
Pressure disequilibria induced by rapid valve closure in noble gas extraction lines
Leah E. Morgan, Brett Davidheiser-Kroll
2015, Geochemistry, Geophysics, Geosystems (16) 1923-1931
Pressure disequilibria during rapid valve closures can affect calculated molar quantities for a range of gas abundance measurements (e.g., K-Ar geochronology, (U-Th)/He geochronology, noble gas cosmogenic chronology). Modeling indicates this effect in a system with a 10 L reservoir reaches a bias of 1% before 1000 pipette aliquants have been...
Testing hypotheses on distribution shifts and changes in phenology of imperfectly detectable species
Thierry A. Chambert, William L. Kendall, James E. Hines, James D. Nichols, Paolo Pedrini, J. Hardin Waddle, Giacomo Tavecchia, Susan C. Walls, Simone Tenan
2015, Methods in Ecology and Evolution (6) 638-647
With ongoing climate change, many species are expected to shift their spatial and temporal distributions. To document changes in species distribution and phenology, detection/non-detection data have proven very useful. Occupancy models provide a robust way to analyse such data, but inference is usually focused on species spatial...
Application of science-based restoration planning to a desert river system
Brian G. Laub, Justin Jimenez, Phaedra E. Budy
2015, Environmental Management (55) 1246-1261
Persistence of many desert river species is threatened by a suite of impacts linked to water infrastructure projects that provide human water security where water is scarce. Many desert rivers have undergone regime shifts from spatially and temporally dynamic ecosystems to more stable systems dominated by homogenous physical habitat. Restoration...
Sediment source apportionment in Laurel Hill Creek, PA, using Bayesian chemical mass balance and isotope fingerprinting
Heather Stewart, Arash Massoudieh, Allen C. Gellis
2015, Hydrological Processes (29) 2545-2560
A Bayesian chemical mass balance (CMB) approach was used to assess the contribution of potential sources for fluvial samples from Laurel Hill Creek in southwest Pennsylvania. The Bayesian approach provides joint probability density functions of the sources' contributions considering the uncertainties due to source and fluvial sample heterogeneity and measurement...

Jacob Carstensen, Riina Klais, James E. Cloern
2015, Estuarine, Coastal and Shelf Science (162) 98-109
Phytoplankton blooms are dynamic phenomena of great importance to the functioning of estuarine and coastal ecosystems. We analysed a unique (large) collection of phytoplankton monitoring data covering 86 coastal sites distributed over eight regions in North America and Europe, with the aim of investigating common patterns in the seasonal timing...
When Siberia came to the Netherlands: The response of continental black-tailed godwits to a rare spring weather event
Nathan R. Senner, Mo A. Verhoeven, Jose M. Abad-Gomez, Jorge S. Gutierrez, Jos C. E. W. Hooijmeijer, Rosemarie Kentie, Jose A. Masero, T. Lee Tibbitts, Theunis Piersma
2015, Journal of Animal Ecology (84) 1164-1176
Summary Extreme weather events have the potential to alter both short- and long-term population dynamics as well as community- and ecosystem-level function. Such events are rare and stochastic, making it difficult to fully document how organisms respond to them and predict the repercussions of similar events in...

Integrated Environmental Modelling: Human decisions, human challenges
Pierre D. Glynn
2015, Geological Society of London Special Publications (408)
Integrated Environmental Modelling (IEM) is an invaluable tool for understanding the complex, dynamic ecosystems that house our natural resources and control our environments. Human behaviour affects the ways in which the science of IEM is assembled and used for meaningful societal applications. In particular, human biases and heuristics reflect adaptation...

Age, growth rates, and paleoclimate studies of deep sea corals
Nancy G Prouty, E. Brendan Roark, Allen Andrews, Laura Robinson, Tessa Hill, Owen Sherwood, Branwen Williams, Thomas P. Guilderson, Stewart Fallon
2015, Report, The state of deep-sea coral and sponge ecosystems of the United States: 2015
Deep-water corals are some of the slowest growing, longest-lived skeletal accreting marine organisms. These habitat-forming species support diverse faunal assemblages that include commercially and ecologically important organisms. Therefore, effective management and conservation strategies for deep-sea corals can be informed by precise and accurate age, growth rate, and lifespan characteristics for...

This report documents the process of developing and refining conceptual ecological models (CEMs) for linking river management to pallid sturgeon (Scaphirhynchus albus) population dynamics in the Missouri River. The refined CEMs are being used in the Missouri River Pallid Sturgeon Effects Analysis to organize, document, and formalize an understanding of...
A stochastic bioenergetics model based approach to translating large river flow and temperature in to fish population responses: The pallid sturgeon example
Mark L. Wildhaber, Rima Dey, Christopher K. Wikle, Edward H. Moran, Christopher J. Anderson, Kristie J. Franz
2015, Geological Society of London Special Publications (408) 1-17
In managing fish populations, especially at-risk species, realistic mathematical models are needed to help predict population response to potential management actions in the context of environmental conditions and changing climate while effectively incorporating the stochastic nature of real world conditions. We provide a key component of such a model for...
