Mitchell J. Eaton, Phillip T. Hughes, James D. Nichols, Anne Morkill, Chad Anderson
2011, Journal of Wildlife Management (75) 1186-1193
Reliable estimates of presence or absence of a species can provide substantial information on management questions related to distribution and habitat use but should incorporate the probability of detection to reduce bias. We surveyed for the endangered Lower Keys marsh rabbit (Sylvilagus palustris hefneri) in habitat patches on 5 Florida...

Ken W. Krauss, Andrew S. From, Thomas W. Doyle, Terry J. Doyle, Michael J. Barry
2011, Journal of Coastal Conservation (15) 629-638
The Ten Thousand Islands region of southwestern Florida, USA is a major feeding and resting destination for breeding, migrating, and wintering birds. Many species of waterbirds rely specifically on marshes as foraging habitat, making mangrove encroachment a concern for wildlife managers. With the alteration of freshwater flow and sea-level rise...

Mead's milkweed Asclepias meadii, a long-lived perennial herb of tallgrass prairie and glade communities of the central United States, is a species designated as threatened under the U.S. Endangered Species Act. Challenges to its successful management include the facts that much about its life history is unknown, its age at...
Modelling community dynamics based on species-level abundance models from detection/nondetection data
Yuichi Yamaura, J. Andrew Royle, Kouji Kuboi, Tsuneo Tada, Susumu Ikeno, Shun’ichi Makino
2011, Journal of Applied Ecology (48) 67-75
1. In large‐scale field surveys, a binary recording of each species’ detection or nondetection has been increasingly adopted for its simplicity and low cost. Because of the importance of abundance in many studies, it is desirable to obtain inferences about abundance at species‐, functional group‐, and community‐levels from such binary data.2. We...
Interspecies transmission and limited persistence of low pathogenic avian influenza genomes among Alaska dabbling ducks
Andrew B. Reeves, John M. Pearce, Andrew M. Ramey, Brandt W. Meixell, Jonathan A. Runstadler
2011, Infection, Genetics and Evolution (11) 2004-2010
The reassortment and geographic distribution of low pathogenic avian influenza (LPAI) virus genes are well documented, but little is known about the persistence of intact LPAI genomes among species and locations. To examine persistence of entire LPAI genome constellations in Alaska, we calculated the genetic identities among 161 full-genome LPAI...
Comparing isotope signatures of prey fish: does gut removal affect δ13C or δ15N?
Steven R. Chipps, Mark J. Fincel, Justin A. VanDeHey, Andrew Wuestewald
2011, Journal of Freshwater Ecology (27) 55-62
Stable isotope analysis is a quick and inexpensive method to monitor the effects of food web changes on aquatic communities. Traditionally, whole specimens have been used when determining isotope composition of prey fish or age-0 recreational fishes. However, gut contents of prey fish could potentially alter isotope composition of the...

To provide accurate and reliable information on sediment near the Fargo-Moorhead metropolitan area, the U.S. Geological Survey in cooperation with the U.S. Army Corps of Engineers conducted a study in the spring (March-May) of 2010 and the spring of 2011 to examine sediment concentrations, loads, and particle-size distributions at nine...
Genetic variation in westslope cutthroat trout Oncorhynchusclarkii lewisi: implications for conservation
Daniel P. Drinan, Steven T. Kalinowski, Ninh V. Vu, Bradley B. Shepard, Clint C. Muhlfeld, Matthew R. Campbell
2011, Conservation Genetics (12) 1513-1523
Twenty-five populations of westslope cutthroat trout from throughout their native range were genotyped at 20 microsatellite loci to describe the genetic structure of westslope cutthroat trout. The most genetic diversity (heterozygosity, allelic richness, and private alleles) existed in populations from the Snake River drainage, while populations from the Missouri River...
Silver bioaccumulation dynamics in a freshwater invertebrate after aqueous and dietary exposures to nanosized and ionic Ag
Marie-Noe le Croteau, Superb K. Misra, Samuel N. Luoma, Eugenia Valsami-Jones
2011, Environmental Science & Technology (45) 6600-6607
We compared silver (Ag) bioavailability and toxicity to a freshwater gastropod after exposure to ionic silver (Ag+) and to Ag nanoparticles (Ag NPs) capped with citrate or with humic acid. Silver form, exposure route, and capping agent influence Ag bioaccumulation dynamics in Lymnaea stagnalis. Snails efficiently accumulated Ag from all...
Migration delays caused by anthropogenic barriers: modeling dams, temperature, and success on migrating salmon smolts
Elizabeth A. Marschall, Martha E. Mather, Donna L. Parrish, Gary W. Allison, James R. McMenemy
2011, Ecological Applications (21) 3014-3031
Disruption to migration is a growing problem for conservation and restoration of animal populations. Anthropogenic barriers along migration paths can delay or prolong migrations, which may result in a mismatch with migration-timing adaptations. To understand the interaction of dams (as barriers along a migration path), seasonally changing environmental conditions, timing...
The role of adsorbed water on the friction of a layer of submicron particles
Charles G. Sammis, David A. Lockner, Ze’ev Reches
2011, Pure and Applied Geophysics (168) 2325-2334
Anomalously low values of friction observed in layers of submicron particles deformed in simple shear at high slip velocities are explained as the consequence of a one nanometer thick layer of water adsorbed on the particles. The observed transition from normal friction with an apparent coefficient near μ = 0.6...

Fred F. Pollitz
2011, Geophysical Journal International (187) 1420-1442
High-frequency and full waveform synthetic seismograms on a 3-D laterally heterogeneous earth model are simulated using the theory of coupled normal modes. The set of coupled integral equations that describe the 3-D response are simplified into a set of uncoupled integral equations by using the Born approximation to calculate scattered...
Genetic discontinuity among regional populations of Lophelia perfusa in the North Atlantic Ocean
Cheryl L. Morrison
2011, Conservation Genetics (12) 713-729
Knowledge of the degree to which populations are connected through larval dispersal is imperative to effective management, yet little is known about larval dispersal ability or population connectivity in Lophelia pertusa, the dominant framework-forming coral on the continental slope in the North Atlantic Ocean. Using nine microsatellite DNA markers, we...
