Changing climate, changing forests: the impacts of climate change on forests of the northeastern United States and eastern Canada
Lindsey Rustad, John Campbell, Jeffrey S. Dukes, Thomas Huntington, Kathy Fallon Lambert, Jacqueline Mohan, Nicholas Rodenhouse
2012, General Technical Report NRS-99
Decades of study on climatic change and its direct and indirect effects on forest ecosystems provide important insights for forest science, management, and policy. A synthesis of recent research from the northeastern United States and eastern Canada shows that the climate of the region has become warmer and wetter over...

P.W. Moran, S.E. Cox, S.S. Embrey, R.L. Huffman, T. D. Olsen, S.C. Fradkin
2012, Scientific Investigations Report 2012-5107
Lake Crescent, in Olympic National Park in the northwest corner of Washington State is a deep-water lake renowned for its pristine water quality and oligotrophic nature. To examine the major sources and sinks of nutrients (as total nitrogen, total phosphorus, and dissolved nitrate), a study was conducted in the Lake...
Pacific salmon (Oncorhynchus spp.) runs and consumer fitness: growth and energy storage in stream-dwelling salmonids increase with salmon spawner density
Daniel J. Rinella, Mark S. Wipfli, Craig A. Stricker, Ron A. Heintz, Matthew J. Rinella
2012, Canadian Journal of Fisheries and Aquatic Sciences (69) 73-84
We examined how marine-derived nutrients (MDN), in the form of spawning Pacific salmon, influenced the nutritional status and δ15N of stream-dwelling fishes. We sampled juvenile coho salmon (Oncorhynchus kisutch) and Dolly Varden (Salvelinus malma) during spring and fall from 11 south-central Alaskan streams that ranged widely in spawning salmon biomass...
Reducing fungal infections and testing tag loss in juvenile Pacific lampreys implanted with passive integrated transponders.
H.E. Christiansen, L.P. Gee, M.G. Mesa
2012, Report
Pacific lamprey Entosphenus tridentatus are facing severe population declines, yet little is known about juvenile lamprey passage, life history, or adult return rates because until now, these small fish could not be tagged for unique identification of live individuals. Previously, we developed a simple and effective method for tagging juvenile...

Effects of Bromus tectorum invasion on microbial carbon and nitrogen cycling in two adjacent undisturbed arid grassland communities
Sean M. Schaeffer, Susan E. Ziegler, Jayne Belnap, R.D. Evans
2012, Biogeochemistry (111) 427-441
Soil nitrogen (N) is an important component in maintaining ecosystem stability, and the introduction of non-native plants can alter N cycling by changing litter quality and quantity, nutrient uptake patterns, and soil food webs. Our goal was to determine the effects of Bromus tectorum (C3) invasion on soil microbial N...

Variation in reproductive life history traits between two populations of Blackbanded Darters (Percina nigrofasciata)
Myra C. Hughey, David C. Heins, Howard L. Jelks, Bridget A. Ory, Frank Jordan
2012, Copeia (4) 714-721
We examined the life history of Blackbanded Darters (Percina nigrofasciata) from two streams in the Choctawhatchee River drainage, Florida, over a three-year study period. Blackbanded Darters from Turkey Creek were longer than fish from Ten Mile Creek; however, size-adjusted clutch and egg sizes were similar between populations. Larger females produced...

2012, Book chapter, The great American carbonate bank: The geology and economic resources of the Cambrian-Ordovician Sauk megasequence of Laurentia
The carbonate strata of the great American carbonate bank (GACB) have been subdivided and correlated with ever-increasing precision and accuracy during the past half century through use of the dominant organisms that evolved on the Laurentian platform through the Cambrian and the Ordovician. Trilobites and conodonts remain the primary groups...

2012, Book chapter, The great American carbonate bank: The geology and economic resources of the Cambrian-Ordovician Sauk megasequence of Laurentia
Analysis of well core and cuttings from the Black Warrior Basin in Mississippi reveals the presence of a Middle Ordovician (Whiterockian) erosional unconformity interpreted to be equivalent to the well-known Knox-Beekmantown unconformity in eastern North America. The unconformity occurs at the top of a peritidal dolostone unit known informally as...
Paired serologic and polymerase chain reaction analyses of avian influenza prevalence in Alaskan shorebirds
John M. Pearce, Daniel R. Ruthrauff, Jeffrey S. Hall
2012, Journal of Wildlife Diseases (48) 812-814
Surveillance has revealed low prevalence of avian influenza viruses (AIV) in shorebirds except Ruddy Turnstones (Arenaria interpres) on the North American Atlantic coast. Similarly, of five species of shorebirds surveyed in Alaska in 2010, Ruddy Turnstones had the highest AIV antibody prevalence; prevalence of AIV RNA was low or zero....

The southern Appalachian part of the Cambrian–Ordovician passive margin succession of the great American carbonate bank extends from the Lower Cambrian to the lower Middle Ordovician, is as much as 3.5 km (2.2 mi) thick, and has long-term subsidence rates exceeding 5 cm (2 in.)/k.y. Subsiding depocenters separated by arches...

Mineral resource of the month: magnesium
Deborah A. Kramer
2012, Earth (57) 29-29
Magnesium is the eighthmost abundant element in Earth’s crust, and the second-most abundant metal ion in seawater. Although magnesium is found in more than 60 minerals, only brucite, dolomite, magnesite and carnallite are commercially important for their magnesium content. Magnesium and its compounds also are recovered from seawater, brines found...
Molecular characterization and comparison of shale oils generated by different pyrolysis methods
Justin E. Birdwell, Jang Mi Jin, Sunghwan Kim
2012, Energy & Fuels (26)
Shale oils generated using different laboratory pyrolysis methods have been studied using standard oil characterization methods as well as Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) with electrospray ionization (ESI) and atmospheric photoionization (APPI) to assess differences in molecular composition. The pyrolysis oils were generated from samples of...

The influence of upper-crust lithology on topographic development in the central Coast Ranges of California
A.F. Garcia, Shannon Mahan
2012, Geomorphology (138) 243-262
A fundamental geological tenet is that as landscapes evolve over graded to geologic time, geologic structures control patterns of topographic distribution in mountainous areas such that terrain underlain by competent rock will be higher than terrain underlain by incompetent rock. This paper shows that in active orogens where markedly...
