Road crossing designs and their impact on fish assemblages of Great Plains streams
Wesley W. Bouska, Craig P. Paukert
2010, Transactions of the American Fisheries Society (139) 214-222
A mark-recapture field study was conducted to determine fish passage at 5 concrete box culverts and 5 low-water crossings (concrete slabs vented by culverts) as well as 10 control sites (below a natural riffle) in Flint Hills streams of northeastern Kansas. Additionally, we tested the upstream passage of four fish...
Modeling and mapping Golden-winged Warbler abundance to improve regional conservation strategies
Wayne E. Thogmartin
2010, Avian Conservation and Ecology (5)
Conservation planning requires identifying pertinent habitat factors and locating geographic locations where land management may improve habitat conditions for high priority species. I derived habitat models and mapped predicted abundance for the Golden-winged Warbler (Vermivora chrysoptera), a species of high conservation concern, using bird counts, environmental variables, and hierarchical models...
Establishing a nationwide baseline of historical burn-severity data to support monitoring of trends in wildfire effects and national fire policies
Brian Schwind, Brad Quayle, Jeffery C. Eidenshink
2010, General Technical Report PNW-GTR-802
There is a need to provide agency leaders, elected officials, and the general public with summary information regarding the effects of large wildfires. Recently, the Wildland Fire Leadership Council (WFLC), which implements and coordinates National Fire Plan (NFP) and Federal Wildland Fire Management Policies adopted a strategy to monitor the...

Significance of dredging on sediment denitrification in Meiliang Bay, China: A year long simulation study
Jicheng Zhong, Chengxin Fan, Lu Zhang, Hall Edward, Shiming Ding, Bao Li, Guofeng Liu
2010, Journal of Environmental Sciences (22) 68-75
An experiment for studying the effects of sediment dredging on denitrification in sediments was carried out through a one-year incubation of undredged (control) and dredged cores in laboratory. Dredging the upper 30 cm of sediment can significantly affect physico-chemical characteristics of sediments. Less degradation of organic matter in the dredged...
Population structure and plumage polymorphism: the intraspecific evolutionary relationships of a polymorphic raptor, Buteo jamaicensis harlani
Joshua M. Hull, David P. Mindell, Sandra L. Talbot, Emily H. Kay, Hopi E. Hoekstra, Holly B. Ernest
2010, BMC Evolutionary Biology (10)
Background Phenotypic and molecular genetic data often provide conflicting patterns of intraspecific relationships confounding phylogenetic inference, particularly among birds where a variety of environmental factors may influence plumage characters. Among diurnal raptors, the taxonomic relationship of Buteo jamaicensis harlani to other B. jamaicensis subspecies has been long debated because of the polytypic nature of the...

Evidence of weak contaminant-related oxidative stress in glaucous gulls (Larus hyperboreus) from the Canadian arctic
Mark Wayland, David J. Hoffman, Mark L. Mallory, Ray T. Alisauskas, Katherine R. Stebbins
2010, Journal of Toxicology and Environmental Health, Part A: Current Issues (73) 1058-1073
Environmental contaminants are transported over great distances to Arctic ecosystems, where they can accumulate in wildlife. Whether contaminant concentrations in wildlife are sufficient to produce adverse effects remains poorly understood. Exposure to contaminants elevates oxidative stress with possible fitness consequences. The glaucous gull (Larus hyperboreus), an Arctic top predator, was...

Introduction to the JEEG Agricultural Geophysics Special Issue
Barry J. Allred, Bruce D. Smith
2010, Journal of Environmental & Engineering Geophysics (15) v-vi
Near-surface geophysical methods have become increasingly important tools in applied agricultural practices and studies. The great advantage of geophysical methods is their potential rapidity, low cost, and spatial continuity when compared to more traditional methods of assessing agricultural land, such as sample collection and laboratory analysis. Agricultural geophysics investigations commonly...

Fish guidance and passage at barriers

Paolo Domenici, B. G. Kapoor, editor(s)
2010, Book chapter, Fish locomotion: An eco-ethological perspective
Habitat fragmentation resulting from human activities is a major factor contributing to reductions in biodiversity and species abundance worldwide. When movements are restricted, subpopulations become isolated, leading to reduced breeding opportunities, inbreeding depression, and interruption of key life stages. This problem is particularly ubiquitous in riverine ecosystems, where dams, water...
Effects of model layer simplification using composite hydraulic properties
Nicasio Sepulveda, Eve L. Kuniansky
2010, Hydrogeology Journal (18) 405-416
The effects of simplifying hydraulic property layering within an unconfined aquifer and the underlying confining unit were assessed. The hydraulic properties of lithologic units within the unconfined aquifer and confining unit were computed by analyzing the aquifer-test data using radial, axisymmetric two-dimensional (2D) flow. Time-varying recharge to the unconfined aquifer...

The biostratigraphic importance of conchostracans in the continental Triassic of the northern hemisphere
H. W. Kozur, Robert E. Weems
2010, Book chapter, The Triassic timescale
Conchostracans or clam shrimp (order Conchostraca Sars) are arthropods with a carapace consisting of two chitinous lateral valves. Triassic conchostracans range in size from 2 to 12.5 mm long and are common in deposits that formed in fresh water lakes, isolated ponds and brackish areas. Their dessication- and freeze-resistant eggs...
