Vegetation and precipitation shifts interact to alter organic and inorganic carbon storage in cold desert soils
David P. Huber, Kathleen A. Lohse, Amy Commendador, Stephen Joy, Ken A. Aho, Bruce P. Finney, Matthew J. Germino
2019, Ecosphere (10)
Dryland ecosystems are experiencing shifts in rainfall and plant community composition, which are expected to alter cycling and storage of soil carbon (C). Few experiments have been conducted to examine long‐term effects on (1) soil organic C (SOC) pools throughout the soil profile, and (2) soil inorganic C (SIC) pools...
Do observer fatigue and taxon-bias compromise visual encounter surveys for small vertebrates?
Bjorn Lardner, Amy A. Yackel Adams, Adam J Knox, Julie A. Savidge, Robert Reed
2019, Wildlife Research (46) 127-135
Context. Visual encounter surveying is a standard animal inventory method, modifications of which (e.g. distance sampling and repeated count surveys) are used for modelling population density. However, a variety of factors may bias visual survey counts.Aims. The aim of the present study was to evaluate three observer-related biases: (1)...

A.R. Main, Elisabeth B. Webb, K. W. Goyne, D. Mengel
2019, Global Ecology and Conservation (17)
Throughout the Midwestern US, many public lands set aside for conservation engage in management activities (e.g., agriculture) that may act as stressors on wild bee populations. Several studies have investigated how wild bees respond to large-scale agriculture production; however, there has been limited assessment of how...

Seyedalireza Khatibi, Mehdi Ostadhassan, Paul C. Hackley, David Tuschel, Arash Abarghani, Bailey Bubach
2019, International Journal of Coal Geology (206) 46-64
Solid organic matter (OM) in sedimentary rocks produces petroleum and solid bitumen when it undergoes thermal maturation. The solid OM is a ‘geomacromolecule’, usually representing a mixture of various organisms with distinct biogenic origins, and can have high heterogeneity in composition. Programmed pyrolysis is a common method to reveal bulk geochemical characteristics of...

H. J. Roop, N. C. Poudyal, Cecil A. Jennings
2019, Journal of the Southeastern Association of Fish and Wildlife Agencies (6) 28-34
Public fishing areas (PFAs) in Georgia are intensively managed freshwater impoundments that provide a variety of fishing opportunities to anglers. Management efforts and fishing regulations at these PFAs depend on understanding basic aspects of recreational fishing pressure, catch, and harvest. Accordingly, we conducted a roving creel survey during January...

2019, FEMS Microbiology Ecology (94)
Controlled laboratory experiments were combined with field measurements to better understand the interactions between dissolved organic matter (DOM) and reduced iron in organic-rich peatlands. Addition of peat-derived humic acid extract (HA) to Sideroxydans lithotrophicus ES-1 liquid cultures led to higher cell numbers and up to 1.4 times higher Fe(II) oxidation...

Detrital K-feldspar Pb isotopic evaluation of extraregional sediment transported through an Eocene tectonic breach of southern California's Cretaceous batholith
Danielle Ziva Shulaker, Marty Grove, Jeremy K. Hourigan, Nicholas Van Buer, Glenn R. Sharman, Keith A. Howard, Jonathan Miller, Andrew P. Barth
2019, Earth and Planetary Science Letters (508) 4-17
Sedimentary provenance studies have come to be overwhelmingly based upon U–Pb geochronologic measurements performed with detrital zircon while alternative and potentially complementary approaches such as conglomerate clast studies and heavy mineral analysis have faded in importance. Measurement of Pb isotopic compositions in detrital K-feldspar is among the under-utilized approaches available to ascertain sedimentary source regions. While it has...

Nathaniel D. Rayl, Kelly Proffitt, Emily S. Almberg, Jennifer D. Jones, Jerod Merkle, Justin A. Gude, Paul C. Cross
2019, Journal of Wildlife Management (83) 817-829
Wildlife reservoirs of infectious disease are a major source of human‐wildlife conflict because of the risk of potential spillover associated with commingling of wildlife and livestock. In the Greater Yellowstone Ecosystem, the presence of brucellosis (Brucella abortus) in free‐ranging elk (Cervus canadensis) populations is of significant management concern because of...
Climate, streamflow, and lake-level trends in the Great Lakes Basin of the United States and Canada, water years 1960–2015
Parker A. Norton, Daniel G. Driscoll, Janet M. Carter
2019, Scientific Investigations Report 2019-5003
Water levels in the Great Lakes fluctuate substantially because of complex interactions among inputs (precipitation and streamflow), outputs (evaporation and outflow), and other factors. This report by the U.S. Geological Survey in cooperation with the Great Lakes Restoration Initiative was completed to describe trends in climate, streamflow, lake levels, and...
Constraining the oxygen isotopic composition of nitrate produced by nitrification
Danielle S. Boshers, Julie Granger, Craig R. Tobias, J.K. Bohlke, Richard L. Smith
2019, Environmental Science & Technology (53) 1206-1216
Measurements of the stable isotope ratios of nitrogen (15N/14N) and oxygen (18O/16O) in nitrate (NO3–) enable identification of sources, dispersal, and fate of natural and contaminant NO3– in aquatic environments. The 18O/16O of NO3– produced by nitrification is often assumed to reflect the proportional contribution of oxygen atom sources, water, and molecular oxygen,...

2019, Landslides (16) 1201-1219
Along the rugged coast of Big Sur, California, the Mud Creek landslide failed catastrophically on May 20, 2017 and destroyed over 400 m of scenic California State Highway 1. We collected structure-from-motion (SfM) photogrammetry data using airborne platforms that, when combined with existing airborne lidar data, revealed that the area...
Molecular characterization of Bathymodiolus mussels and gill symbionts associated with chemosynthetic habitats from the U.S. Atlantic margin
Dolly Coykendall, Robert S. Cornman, Nancy G. Prouty, Sandra Brooke, Amanda W. J. Demopoulos, Cheryl L. Morrison
2019, PLoS ONE (14)
Mussels of the genus Bathymodiolus are among the most widespread colonizers of hydrothermal vent and cold seep environments, sustained by endosymbiosis with chemosynthetic bacteria. Presumed species of Bathymodiolus are abundant at newly discovered cold seeps on the Mid-Atlantic continental slope, however morphological taxonomy is challenging, and their phylogenetic affinities remain...
