The aging of America's reservoirs: In-reservoir and downstream physical changes and habitat implications
Kyle E. Juracek
2015, Journal of the American Water Resources Association (51) 168-184
Reservoirs are important for various purposes including flood control, water supply, power generation, and recreation. The aging of America's reservoirs and progressive loss of water storage capacity resulting from ongoing sedimentation, coupled with increasing societal needs, will cause the social, economic, environmental, and political importance of reservoirs to continually increase....
Genetic diversity and host specificity varies across three genera of blood parasites in ducks of the Pacific Americas Flyway
Andrew B. Reeves, Matthew M. Smith, Brandt W. Meixell, Joseph P. Fleskes, Andrew M. Ramey
2015, PLoS ONE (10)
Birds of the order Anseriformes, commonly referred to as waterfowl, are frequently infected by Haemosporidia of the genera Haemoproteus, Plasmodium, and Leucocytozoon via dipteran vectors. We analyzed nucleotide sequences of the Cytochrome b (Cytb) gene from parasites of these genera detected in six species of ducks from Alaska and California,...
Vegetation burn severity mapping using Landsat-8 and WorldView-2
Zhuoting Wu, Barry R. Middleton, Robert Hetzler, John M. Vogel, Dennis G. Dye
2015, Photogrammetric Engineering and Remote Sensing (2) 143-154
We used remotely sensed data from the Landsat-8 and WorldView-2 satellites to estimate vegetation burn severity of the Creek Fire on the San Carlos Apache Reservation, where wildfire occurrences affect the Tribe's crucial livestock and logging industries. Accurate pre- and post-fire canopy maps at high (0.5-meter) resolution were created from...
Inter-annual and spatial variability of Hamon potential evapotranspiration model coefficients
Gregory J. McCabe, Lauren E. Hay, Andy Bock, Steven L. Markstrom, R. Dwight Atkinson
2015, Journal of Hydrology (521) 389-394
Monthly calibrated values of the Hamon PET coefficient (C) are determined for 109,951 hydrologic response units (HRUs) across the conterminous United States (U.S.). The calibrated coefficient values are determined by matching calculated mean monthly Hamon PET to mean monthly free-water surface evaporation. For most locations and months the calibrated coefficients...
Petrologic testament to changes in shallow magma storage and transport during 30+ years of recharge and eruption at Kīlauea Volcano, Hawai‘i
Carl R. Thornber, Tim R. Orr, Christina Heliker, Richard P. Hoblitt
Rebecca Carey, Valerie Cayol, Michael P. Poland, Dominique Weis, editor(s)
2015, Geophysical Monograph 8
Petrologic monitoring of Kīlauea Volcano from January 1983 to October 2013 has yielded an extensive record of glass, phenocryst, melt inclusion, and bulk-lava chemistry from well-quenched lava. When correlated with 30+ years of geophysical and geologic monitoring, petrologic details testify to physical maturation of summit-to-rift magma plumbing associated with...
The role of water in unconventional in situ energy resource extraction technologies
Tanya J. Gallegos, Carleton R. Bern, Justin E. Birdwell, Seth S. Haines, Mark A. Engle
Satinder Ahuja, editor(s)
2015, Book chapter, Food, energy, and water: The chemistry connection
Global trends toward developing new energy resources from lower grade, larger tonnage deposits that are not generally accessible using “conventional” extraction methods involve variations of subsurface in situ extraction techniques including in situ oil shale retorting, hydraulic fracturing of petroleum reservoirs, and in situ recovery of uranium. Although these methods are...
Ecosystem-atmosphere exchange of CO2 in a temperate herbaceous peatland in the Sanjiang Plain of northeast China
Xiaoyan Zhu, Changchun Song, Christopher M. Swarzenski, Yuedong Guo, Xinhow Zhang, Jiaoyue Wang
2015, Ecological Engineering (75) 16-23
Northern peatlands contain a considerable share of the terrestrial carbon pool, which will be affected by future climatic variability. Using the static chamber technique, we investigated ecosystem respiration and soil respiration over two growing seasons (2012 and 2013) in a Carex lasiocarpa-dominated peatland in the Sanjiang Plain in China. We...
Suspended-sediment trapping in the tidal reach of an estuarine tributary channel
Maureen A. Downing-Kunz, David H. Schoellhamer
2015, Estuaries and Coasts (38) 2198-2212
Evidence of decreasing sediment supply to estuaries and coastal oceans worldwide illustrates the need for accurate and updated estimates. In the San Francisco Estuary (Estuary), recent research suggests a decrease in supply from its largest tributaries, implying the increasing role of smaller, local tributaries in sediment supply to this estuary....
Assessing the likely effectiveness of multispecies management for imperiled desert fishes with niche overlap analysis
P Laub, Phaedra Budy
2015, Conservation Biology (29) 1153-1163
A critical decision in species conservation is whether to target individual species or a complex of ecologically similar species. Management of multispecies complexes is likely to be most effective when species share similar distributions, threats, and response to threats. We used niche overlap analysis to assess ecological similarity of...

Characterizing the distribution of an endangered salmonid using environmental DNA analysis
Matthew B. Laramie, David S. Pilliod, Caren S. Goldberg
2015, Biological Conservation (183) 29-37
Determining species distributions accurately is crucial to developing conservation and management strategies for imperiled species, but a challenging task for small populations. We evaluated the efficacy of environmental DNA (eDNA) analysis for improving detection and thus potentially refining the known distribution of Chinook salmon (Oncorhynchus tshawytscha) in the Methow and...
Quantification of eDNA shedding rates from invasive bighead carp Hypophthalmichthys nobilis and silver carp Hypophthalmichthys molitrix
Katy E. Klymus, Cathy A. Richter, Duane Chapman, Craig P. Paukert
2015, Biological Conservation (183) 77-84
Wildlife managers can more easily mitigate the effects of invasive species if action takes place before a population becomes established. Such early detection requires sensitive survey tools that can detect low numbers of individuals. Due to their high sensitivity, environmental DNA (eDNA) surveys hold promise as an early detection method...
Geographically isolated wetlands: Rethinking a misnomer
David M. Mushet, Aram J.K. Calhoun, Laurie C. Alexander, Matthew J. Cohen, Edward S. DeKeyser, Laurie G. Fowler, Charles R. Lane, Megan W. Lang, Mark C. Rains, Susan C. Walls
2015, Wetlands (35) 423-431
We explore the category “geographically isolated wetlands” (GIWs; i.e., wetlands completely surrounded by uplands at the local scale) as used in the wetland sciences. As currently used, the GIW category (1) hampers scientific efforts by obscuring important hydrological and ecological differences among multiple wetland functional types, (2) aggregates wetlands in...
The influence of disturbed habitat on the spatial ecology of Argentine black and white tegu (Tupinambis merianae), a recent invader in the Everglades ecosystem (Florida, USA)
Page E. Klug, Robert N. Reed, Frank J. Mazzotti, Michelle A. McEachern, Joy J. Vinci, Katelin K. Craven, Amy A. Yackel Adams
2015, Biological Invasions (17) 1785-1797
The threat of invasive species is often intensified in disturbed habitat. To optimize control programs, it is necessary to understand how degraded habitat influences the behavior of invasive species. We conducted a radio telemetry study to characterize movement and habitat use of introduced male Argentine black and white tegus (Tupinambis...
Intercontinental genetic structure and gene flow in Dunlin (Calidris alpina), a potential vector of avian influenza

Waterfowl (Anseriformes) and shorebirds (Charadriiformes) are the most common wild vectors of influenza A viruses. Due to their migratory behavior, some may transmit disease over long distances. Migratory connectivity studies can link breeding and nonbreeding grounds while illustrating potential interactions among populations that may spread diseases. We investigated Dunlin (Calidris...

2015, North American Journal of Fisheries Management (35) 20-30
Atlantic Sturgeon Acipenser oxyrinchus oxyrinchus was federally listed under the U.S. Endangered Species Act as five distinct population segments (DPS). Currently, at least 18 estuaries coastwide host spawning populations and the viability of these vary, requiring differing levels of protection. Subadults emigrate from their natal estuaries to marine waters where they are...
