Ecopathology Of Ranaviruses Infecting Amphibians., 2010 University of Tennessee, Knoxville
Ecopathology Of Ranaviruses Infecting Amphibians., Debra Miller, Matthew Gray, A. Storfer
Debra L Miller
Ranaviruses are capable of infecting amphibians from at least 14 families and over 70 individual species. Ranaviruses infect multiple cell types, often culminating in organ necrosis and massive hemorrhaging. Subclinical infections have been documented, although their role in ranavirus persistence and emergence remains unclear. Water is an effective transmission medium for ranaviruses, and survival outside the host may be for significant duration. In aquatic communities, amphibians, reptiles and fish may serve as reservoirs. Controlled studies have shown that susceptibility to ranavirus infection and disease varies among amphibian species and developmental stages, and likely is impacted by host-pathogen coevolution, as well ...
Calibrating Divergence Times On Species Tree Versus Gene Trees: Implications For Speciation History Of Aphelocoma Jays, John Mccormack, Joseph Heled, Kathleen Delaney, A. Peterson, L. Knowles
John E. McCormack
Estimates of the timing of divergence are central to testing the underlying causes of speciation. Relaxed molecular clocks and fossil calibration have improved these estimates; however, these advances are implemented in the context of gene trees, which can overestimate divergence times. Here we couple recent innovations for dating speciation events with the analytical power of species trees, where multilocus data are considered in a coalescent context. Divergence times are estimated in the bird genus Aphelocoma to test whether speciation in these jays coincided with mountain uplift or glacial cycles. Gene trees and species trees show general agreement that diversification began ...

Streptococcus Phocae Isolated From A Spotted Seal ( Phoca Largha) With Pyometra In Alaska., 2010 University of Tennessee, Knoxville
Streptococcus Phocae Isolated From A Spotted Seal ( Phoca Largha) With Pyometra In Alaska., K. Hueffer, C. Lieske, L. Mcgilvary, R. Hare, Debra Miller, T. O'Hara
Debra L Miller
A spotted seal harvested by subsistence hunters in Kotzebue Sound, Alaska (USA), showed a grossly enlarged uterus and associated lymph nodes. Streptococcus phocae was isolated from the purulent uterine discharge. Histopathologic examination revealed inflammation that was limited to the uterine mucosa. Lymph nodes draining the affected organ were reactive but no evidence of active infection was found in the lymph nodes. This report is the first Streptococcus phocae isolated from spotted seals as well as the first report of pyometra as the main pathologic finding associated with this pathogen. Isolation of this pathogen from Alaska expands the reported range to ...

Embryonic Staging Table For A Direct- Developing Salamander, Plethodon Cinereus (Plethodontidae), 2010 Dalhousie University
Embryonic Staging Table For A Direct- Developing Salamander, Plethodon Cinereus (Plethodontidae), Ryan Kerney
This work presents a refined staging table for the direct-developing red-backed salamander Plethodon cinereus, which is based on the incom- plete staging system of James Norman Dent (J Morphol 1942; 71:577– 601). This common species from eastern North America is a member of the species-rich lungless salamander family Plethodontidae. The stag- ing table presented here covers several stages omitted by Dent and reveals novel developmental features of P. cinereus embryos. These include putative Leydig cells and open gill clefts, which are found in lar- vae of metamorphosing species but were previously reported as absent in direct-developing Plethodon. Other features ...
Smooth Crabgrass Control With Indaziflam At Various Spring Timings, 2010 University of Tennessee, Knoxville
Smooth Crabgrass Control With Indaziflam At Various Spring Timings, Jim Brosnan, P Mccullough, G Breeden
Indaziflam is an alkylazine herbicide that controls annual grasses by inhibiting cellulose biosynthesis. Compared with other PRE herbicides like prodiamine, indaziflam has a longer half-life in soil (> 150 d), which may allow for greater flexibility with application timing. Research was conducted in 2010 in Tennessee and Georgia evaluating smooth crabgrass control efficacy with indaziflam applied at early PRE, PRE, and early POST timings on the basis of soil temperature. Regardless of application timing, all rates of indaziflam (35, 52.5, and 70 g ai ha−1) controlled smooth crabgrass 89 to 100%. Prodiamine at 840 g ai ha−1 applied ...
Molecular-Genetic Mapping Of Zebrafish Mutants With Variable Phenotypic Penetrance, 2010 University of Pennsylvania
Molecular-Genetic Mapping Of Zebrafish Mutants With Variable Phenotypic Penetrance, Roshan Jain, Marc Wolman, Lauren Schmidt, Harold Burgess, Michael Granato
Roshan A Jain
Forward genetic screens in vertebrates are powerful tools to generate models relevant to human diseases, including neuropsychiatric disorders. Variability in phenotypic penetrance and expressivity is common in these disorders and behavioral mutant models, making their molecular-genetic mapping a formidable task. Using a ‘phenotyping by segregation’ strategy, we molecularly map the hypersensitive zebrafish houdini mutant despite its variable phenotypic penetrance, providing a generally applicable strategy to map zebrafish mutants with subtle phenotypes.

Adaptation As Process: The Future Of Darwinism And The Legacy Of Theodosius Dobzhansky, 2010 University of Iowa
Adaptation As Process: The Future Of Darwinism And The Legacy Of Theodosius Dobzhansky, David Depew
David J Depew
Conceptions of adaptation have varied in the history of genetic Darwinism depending on whether what is taken to be focal is the process of adaptation, adapted states of populations, or discrete adaptations in individual organisms. I argue that Theodosius Dobzhansky’s view of adaptation as a dynamical process contrasts with so-called “adaptationist” views of natural selection figured as “design-without-a-designer” of relatively discrete, enumerable adaptations. Correlated with these respectively process and product oriented approaches to adaptive natural selection are divergent pictures of organisms themselves as developmental wholes or as “bundles” of adaptations. While even process versions of genetical Darwinism are insufficiently ...
Size Of Food Bowl And Scoop Affects Amount Of Food Owners Feed Their Dogs, 2010 University of Tennessee - Knoxville
Size Of Food Bowl And Scoop Affects Amount Of Food Owners Feed Their Dogs, Maryanne Murphy, Angela Witzel, Joe Bartges, Claudia Kirk
Claudia A Kirk
The incidence of canine obesity appears to be increasing dramatically and understanding factors impacting the amount of food pet owners provide their dogs may improve weight management. Human research has shown the size of food bowls, plates and utensils can significantly impact the amount of food portioned and consumed. This effect can be attributed to both the Delboeuf optical illusion and the Ebbinghaus-Titchener size-contrast illusion. To investigate the existence of a similar effect with dog owners, 54 dogs and their owners were recruited for a four treatment randomized prospective trial. Owners scooped out a normal kibble-based meal using a small ...

Global Comparison Of Warring Groups In 2002-2007: Fatalities From Targeting Civilians Vs. Fighting Battles., M Hicks, U Lee, R Sundberg, M Spagat
Madelyn Hsiao-Rei Hicks
Warring groups that compete to dominate a civilian population confront contending behavioral options: target civilians or battle the enemy. We aimed to describe degrees to which combatant groups concentrated lethal behavior into intentionally targeting civilians as opposed to engaging in battle with opponents in contemporary armed conflict.
We identified all 226 formally organized state and non-state groups (i.e. actors) that engaged in lethal armed conflict during 2002-2007: 43 state and 183 non-state. We summed civilians killed by an actor's intentional targeting with civilians and combatants killed in battles in which the actor was involved ...
Serotonin Transporter (5-Httlpr) Genotype And Childhood Trauma Are Associated With Individual Differences In Decision Making, Scott Stoltenberg
Scott F. Stoltenberg
The factors that influence individual differences in decision making are not yet fully characterized, but convergent evidence is accumulating that implicates serotonin (5-HT) system function. Therefore, both genes and environments that influence serotonin function are good candidates for association with risky decision making. In the present study we examined associations between common polymorphisms in the serotonin transporter gene (SLC6A4; 5-HTTLPR and rs25531), the experience of childhood trauma and decision making on the Iowa gambling task (IGT) in 391 (64.5% female) healthy Caucasian adults. Homozygosity for the 5-HTTLPR L allele was associated with riskier decision making in the first block ...
