We report the whole-genome sequence of the common marmoset (Callithrix jacchus). The 2.26-Gb genome of a female marmoset was assembled using Sanger read data (6×) and a whole-genome shotgun strategy. A first analysis has permitted comparison with the genomes of apes and Old World monkeys and the identification of specific features that might contribute to the unique biology of this diminutive primate, including genetic changes that may influence body size, frequent twinning and chimerism. We observed positive selection in growth hormone/insulin-like growth factor genes (growth pathways), respiratory complex I genes (metabolic pathways), and genes encoding immunobiological factors and proteases (reproductive …

The Psbp Domain Protein 1 Functions In The Assembly Of Lumenal Domains In Photosystem I, Johnna L. Roose, Laurie K. Frankel, Terry M. Bricker Jan 2014

The Psbp Domain Protein 1 Functions In The Assembly Of Lumenal Domains In Photosystem I, Johnna L. Roose, Laurie K. Frankel, Terry M. Bricker

Faculty Publications

Photosystem I (PS I) is a multisubunit membrane protein complex that functions as a light-driven plastocyanin-ferredoxin oxidoreductase. The PsbP domain protein 1 (PPD1; At4g15510) is located in the thylakoid lumen of plant chloroplasts and is essential for photoautotrophy, functioning as a PS I assembly factor. In this work, RNAi was used to suppress PPD1 expression, yielding mutants displaying a range of phenotypes with respect to PS I accumulation and function. These PPD1 RNAi mutants showed a loss of assembled PS I that was correlated with loss of the PPD1 protein. In the most severely affected PPD1 RNAi lines, the accumulated …

Poor Fit To The Multispecies Coalescent Is Widely Detectable In Empirical Data, Noah M. Reid, Sarah M. Hird, Jeremy M. Brown, Tara A. Pelletier, John D. Mcvay, Jordan D. Satler, Bryan C. Carstens Jan 2014

Poor Fit To The Multispecies Coalescent Is Widely Detectable In Empirical Data, Noah M. Reid, Sarah M. Hird, Jeremy M. Brown, Tara A. Pelletier, John D. Mcvay, Jordan D. Satler, Bryan C. Carstens

Faculty Publications

Model checking is a critical part of Bayesian data analysis, yet it remains largely unused in systematic studies. Phylogeny estimation has recently moved into an era of increasingly complex models that simultaneously account for multiple evolutionary processes, the statistical fit of these models to the data has rarely been tested. Here we develop a posterior predictive simulation-based model check for a commonly used multispecies coalescent model, implemented in *BEAST, and apply it to 25 published data sets. We show that poor model fit is detectable in the majority of data sets; that this poor fit can mislead phylogenetic estimation; and …

Systematics Of The Obligate Ant-Following Clade Of Antbirds (Aves: Passeriformes: Thamnophilidae), Morton L. Isler, Gustavo A. Bravo, Robb T. Brumfield Jan 2014

Systematics Of The Obligate Ant-Following Clade Of Antbirds (Aves: Passeriformes: Thamnophilidae), Morton L. Isler, Gustavo A. Bravo, Robb T. Brumfield

Faculty Publications

© 2014 by the Wilson Ornithological Society. Results of a comprehensive molecular phylogeny of the family Thamnophilidae were consistent with earlier findings that almost all obligate army-ant-followers of the family form a monophyletic group that contains five well-supported clades and encompasses six currently recognized genera: Phaenostictus, Pithys, Willisornis, Gymnopithys, Rhegmatorhina, and Phlegopsis. A comparative analysis of seven suites of morphological, behavioral, and ecological traits within the context of the phylogeny reinforced the validity of five of these genera, but results for the sixth, Gymnopithys, were internally inconsistent and required the description of a new genus, Oneillornis.

Sampling Locality Is More Detectable Than Taxonomy Or Ecology In The Gut Microbiota Of The Brood-Parasitic Brown-Headed Cowbird (Molothrus Ater), Sarah M. Hird, Bryan C. Carstens, Steven W. Cardiff, Donna L. Dittmann, Robb T. Brumfield Jan 2014

Sampling Locality Is More Detectable Than Taxonomy Or Ecology In The Gut Microbiota Of The Brood-Parasitic Brown-Headed Cowbird (Molothrus Ater), Sarah M. Hird, Bryan C. Carstens, Steven W. Cardiff, Donna L. Dittmann, Robb T. Brumfield

Faculty Publications

Brown-headed Cowbirds (Molothrus ater) are the most widespread avian brood parasite in North America, laying their eggs in the nests of approximately 250 host species that raise the cowbird nestlings as their own. It is currently unknown how these heterospecific hosts influence the cowbird gut microbiota relative to other factors, such as the local environment and genetics. We test a Nature Hypothesis (positing the importance of cowbird genetics) and a Nurture Hypothesis (where the host parents are most influential to cowbird gut microbiota) using the V6 region of 16S rRNA as a microbial fingerprint of the gut from 32 cowbird …

Adaptive Processes Drive Ecomorphological Convergent Evolution In Antwrens (Thamnophilidae), Gustavo A. Bravo, J. V. Remsen, Robb T. Brumfield Jan 2014

Adaptive Processes Drive Ecomorphological Convergent Evolution In Antwrens (Thamnophilidae), Gustavo A. Bravo, J. V. Remsen, Robb T. Brumfield

Faculty Publications

© 2014 The Author(s). Phylogenetic niche conservatism (PNC) and convergence are contrasting evolutionary patterns that describe phenotypic similarity across independent lineages. Assessing whether and how adaptive processes give origin to these patterns represent a fundamental step toward understanding phenotypic evolution. Phylogenetic model-based approaches offer the opportunity not only to distinguish between PNC and convergence, but also to determine the extent that adaptive processes explain phenotypic similarity. The Myrmotherula complex in the Neotropical family Thamnophilidae is a polyphyletic group of sexually dimorphic small insectivorous forest birds that are relatively homogeneous in size and shape. Here, we integrate a comprehensive species-level molecular …

Target Capture And Massively Parallel Sequencing Of Ultraconserved Elements For Comparative Studies At Shallow Evolutionary Time Scales, Brian Tilston Smith, Michael G. Harvey, Brant C. Faircloth, Travis C. Glenn, Robb T. Brumfield Jan 2014

Target Capture And Massively Parallel Sequencing Of Ultraconserved Elements For Comparative Studies At Shallow Evolutionary Time Scales, Brian Tilston Smith, Michael G. Harvey, Brant C. Faircloth, Travis C. Glenn, Robb T. Brumfield

Faculty Publications

Comparative genetic studies of non-model organisms are transforming rapidly due to major advances in sequencing technology. A limiting factor in these studies has been the identification and screening of orthologous loci across an evolutionarily distant set of taxa. Here, we evaluate the efficacy of genomic markers targeting ultraconserved DNA elements (UCEs) for analyses at shallow evolutionary timescales. Using sequence capture and massively parallel sequencing to generate UCE data for five co-distributed Neotropical rainforest bird species, we recovered 776-1516 UCE loci across the five species. Across species, 53-77% of the loci were polymorphic, containing between 2.0 and 3.2 variable sites per …

Intergenic Transcriptional Interference Is Blocked By Rna Polymerase Iii Transcription Factor Tfiiib In Saccharomyces Cerevisiae, Asawari Korde, Jessica M. Rosselot, David Donze Jan 2014

Intergenic Transcriptional Interference Is Blocked By Rna Polymerase Iii Transcription Factor Tfiiib In Saccharomyces Cerevisiae, Asawari Korde, Jessica M. Rosselot, David Donze

Faculty Publications

The major function of eukaryotic RNA polymerase III is to transcribe transfer RNA, 5S ribosomal RNA, and other small non-protein-coding RNA molecules. Assembly of the RNA polymerase III complex on chromosomal DNA requires the sequential binding of transcription factor complexes TFIIIC and TFIIIB. Recent evidence has suggested that in addition to producing RNA transcripts, chromatin-assembled RNA polymerase III complexes may mediate additional nuclear functions that include chromatin boundary, nucleosome phasing, and general genome organization activities. This study provides evidence of another such "extratranscriptional" activity of assembled RNA polymerase III complexes, which is the ability to block progression of intergenic RNA …

Effects Of Coastal Urbanization On Salt-Marsh Faunal Assemblages In The Northern Gulf Of Mexico, Michael R. Lowe, Mark S. Peterson Jan 2014

Effects Of Coastal Urbanization On Salt-Marsh Faunal Assemblages In The Northern Gulf Of Mexico, Michael R. Lowe, Mark S. Peterson

Faculty Publications

Coastal landscapes in the northern Gulf of Mexico, specifically the Mississippi coast, have undergone rapid urbanization that may impact the suitability of salt-marsh ecosystems for maintaining and regulating estuarine faunal communities. We used a landscape ecology approach to quantify the composition and configuration of salt-marsh habitats and developed surfaces at multiple spatial scales surrounding three small, first-order salt-marsh tidal creeks arrayed along a gradient of urbanization in two river-dominated estuaries. From May 3 to June 4, 2010, nekton and macroinfauna were collected weekly at all six sites. Due to the greater abundance of grass shrimp Palaemonetes spp., brown shrimp Farfantepenaeus …

Preserving The Historic Garden Suburb: Case Studies From London And New York, Jeffrey A. Kroessler Jan 2014

Preserving The Historic Garden Suburb: Case Studies From London And New York, Jeffrey A. Kroessler

Publications and Research

The garden city or garden suburb was a response to the social and environmental ills of cities at the turn of the twentieth century. Letchworth Garden City, Hampstead Garden Suburb, and Welwyn Garden City were built outside London in the early 1900s, and each remains a highly desirable place of residence today. From the start, each was tightly regulated, and remains so a century later. By protecting the appearance and enhancing property values, the strict application of historic preservation principles contribute to the long-term sustainability of each place. Similar garden suburbs were built in the borough of Queens in New …

Linguistic Behavior And Religious Activity, Wendy Baker, David Bowie Jan 2014

Linguistic Behavior And Religious Activity, Wendy Baker, David Bowie

Faculty Publications

Studies have found that Mormons and non-Mormons in Utah exhibit significant linguistic differences. We break this down further by investigating whether there are also differences between Mormons who actively participate in the religion and those who do not, and find significant differences with a medium or larger effect size between the groups for multiple variables. We conclude that when investigating the linguistic correlates of religious affiliation in a community, it is vital to elicit not just respondents’ religious affiliations, but also their level of participation within that religion.

Social Anxiety And Coping Motives For Cannabis Use: The Impact Of Experiential Avoidance, Julia D. Buckner, Michael J. Zvolensky, Samantha G. Farris, Julianna Hogan Jan 2014

Social Anxiety And Coping Motives For Cannabis Use: The Impact Of Experiential Avoidance, Julia D. Buckner, Michael J. Zvolensky, Samantha G. Farris, Julianna Hogan

Faculty Publications

Social anxiety is robustly associated with cannabis-related problems. This relation appears to be largely explained by coping-oriented motives for cannabis use. Yet, factors associated with coping motives among socially anxious individuals have yet to be identified. The current study tested whether experiential avoidance (i.e., unwillingness to experience distressing internal states) and its subfacets mediated the relation between social anxiety and coping motives for cannabis use. The sample consisted of current (past-month) cannabis-using adults (n = 103). Results indicated that social anxiety was robustly related to experiential avoidance, which was robustly related to coping motives. Follow-up analyses indicated that behavioral avoidance …

In a study of almost 16 000 nest records from seven swallow species across the entire Western Hemisphere, clutch sizes decline with relative laying date in each population, but the slope of this decline grows steeper with increasing distance from the equator. Late-laying birds at all latitudes lay clutches of similar sizes, suggesting that latitudinal differences may be driven primarily by earlier-laying birds. Focused comparisons of site-years in North America with qualitatively different food availability indicate that food supply significantly affects mean clutch size but not the clutch size-lay date regression. Other studies on the seasonality of swallow food also …

Habitat fragmentation studies have produced complex results that are challenging to synthesize. Inconsistencies among studies may result from variation in the choice of landscape metrics and response variables, which is often compounded by a lack of key statistical or methodological information. Collating primary datasets on biodiversity responses to fragmentation in a consistent and flexible database permits simple data retrieval for subsequent analyses. We present a relational database that links such field data to taxonomic nomenclature, spatial and temporal plot attributes, and environmental characteristics. Field assessments include measurements of the response(s) (e.g., presence, abundance, ground cover) of one or more species …

Seven Decades Of Development Of The Maize Production System, João Carlos Cardoso Galvão, Glauco Vieira Miranda, Emerson Trogello, Roberto Fritsche-Neto

Faculty Publications

The objective of this work was to compare the maize production system recommended in the decade of 1940 with the system currently employed in Brazil. We used the paper published by Antônio Secundino de São José at Revista Ceres in 1944 to compare the agricultural practices used at that time with the ones currently employed. In the 40's, we found no direct concern with aspects of soil and water conservation. However, the process of raising grain yield based on the use of more on-farm inputs , such as manure and seeds, was initiated at that time. The maize crop was …

Faculty Publications

Objective: Obesity is linked to insulin resistance, a primary component of metabolic syndrome and type 2 diabetes. The problem of obesity-related insulin resistance is compounded when age-related skeletal muscle loss, called sarcopenia, occurs with obesity. Skeletal muscle loss results from elevated levels of protein degradation and prevention of obesity-related sarcopenic muscle loss will depend on strategies that target pathways involved in protein degradation. An extract from Artemisia dracunculus, termed PMI 5011, improves insulin signaling and increases skeletal muscle myofiber size in a rodent model of obesity-related insulin resistance. The aim of this study was to examine the effect of PMI …

Rice is the most important food security crop in Asia. Information on its seasonal extent forms part of the national accounting of many Asian countries. Synthetic Aperture Radar (SAR) imagery is highly suitable for detecting lowland rice, especially in tropical and subtropical regions, where pervasive cloud cover in the rainy seasons precludes the use of optical imagery. Here, we present a simple, robust, rule-based classification for mapping rice area with regularly acquired, multi-temporal, X-band, HH-polarized SAR imagery and site-specific parameters for classification. The rules for rice detection are based on the well-studied temporal signature of rice from SAR backscatter and …

Plants capture solar energy and atmospheric carbon dioxide (CO 2) through photosynthesis, which is the primary component of crop yield, and needs to be increased considerably to meet the growing global demand for food. Environmental stresses, which are increasing with climate change, adversely affect photosynthetic carbon metabolism (PCM) and limit yield of cereals such as rice (Oryza sativa) that feeds half the world. To study the regulation of photosynthesis, we developed a rice gene regulatory network and identified a transcription factor HYR (HIGHER YIELD RICE) associated with PCM, which on expression in rice enhances photosynthesis under multiple environmental conditions, determining …

Estimating Microzooplankton Grazing Half-Saturation Constants From Dilution Experiments With Nonlinear Feeding Kinetics, Bingzhang Chen, Edward A. Laws, Hongbin Liu, Bangqin Huang Jan 2014

Estimating Microzooplankton Grazing Half-Saturation Constants From Dilution Experiments With Nonlinear Feeding Kinetics, Bingzhang Chen, Edward A. Laws, Hongbin Liu, Bangqin Huang

Faculty Publications

To obtain the grazing half-saturation constant (K) of natural microzooplankton assemblages, we used three nonlinear grazing models (rectilinear, Holling type II, and Holling type III) to fit the detailed data (phytoplankton net specific growth rate vs. dilution factor) of individual dilution experiments that show significant concave curves. In the dataset consisting of 528 experiments, 96 experiments show significant concave curves, and the associated chlorophyll a (Chl a) concentrations are significantly higher than those of experiments showing linear or convex curves. Experiments showing concave curves likely reflect that these microzooplankton assemblages were under top-down control. The three models perform equally well …
