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...

2010, Report
We conducted a natural resource assessment of Rocky Mountain National Park (ROMO) to provide a synthesis of existing scientific data and knowledge to address the current conditions for a subset of important park natural resources. The intent is for this report to help provide park resource managers with data and...
Biodegration of chlorinated ethenes
Paul M. Bradley, Francis H. Chapelle
2010, Book chapter, In situ remediation of chlorinated solvent plumes
Biodegradation of chlorinated ethenes by naturally occurring or artificially enhanced processes is an important component of current site remediation strategies. At this writing, several microbial mechanisms for chlorinated ethene transformation and degradation have been identified. The purpose of this chapter is to briefly summarize the current understanding of those processes...
Workshop targets development of geodetic transient detection methods: 2009 SCEC Annual Meeting: Workshop on transient anomalous strain detection; Palm Springs, California, 12-13 September 2009

The Southern California Earthquake Center (SCEC) is a community of researchers at institutions worldwide working to improve understanding of earthquakes and mitigate earthquake risk. One of SCEC's priority objectives is to “develop a geodetic network processing system that will detect anomalous strain transients.” Given the growing number of continuously recording...

Iceberg calving as a primary source of regional‐scale glacier‐generated seismicity in the St. Elias Mountains, Alaska
Shad O’Neel, Christopher F. Larsen, Natalia Rupert, Roger Hansen
2010, Journal of Geophysical Research F: Earth Surface (115)
Since the installation of the Alaska Regional Seismic Network in the 1970s, data analysts have noted nontectonic seismic events thought to be related to glacier dynamics. While loose associations with the glaciers of the St. Elias Mountains have been made, no detailed study of the source locations has been undertaken....
Evidence of mating readiness in certain bats killed by wind turbines
Paul M. Cryan, Joel W. Jameson, Erin F. Baerwald, Craig K. R. Willis, Robert M.R. Barclay, Elise A. Snider, Elizabeth G. Crichton
2010, Conference Paper, North American Symposium on Bat Research: 40th Annual Meeting
Bats consistently die at wind turbines during late-summer and autumn. Migratory, tree-roosting species show increased susceptibility compared to other bats, yet the exact causes remain unknown. A hypothesized cause with strong conservation implications is that migratory tree bats die at turbines while seeking mates around tall tree like structures. In this...

2010, Wildlife Research (37) 392-400
Context. Despite their economic importance and intensive management, many game bird species, including the northern bobwhite Colinus virginianus, are in decline. Declines may be explained, at least in part, by low survival due perhaps to poor habitat quality, high predation or excessive hunting pressure.Aims. This study sought to estimate and...
