Complex Evolution Of A Highly-Conserved Microsatellite Locus In Several Fish Species, J.-X. Liu, Bert Ely

Faculty Publications

The evolutionary dynamics of a highly conserved microsatellite locus (Dla 11) were studied in several fish species. The data indicated that multiple types of compound microsatellites arose through point mutations that were sometimes followed by expansion of the derived motif. Furthermore, extensive length variation was detected among species in the regions immediately flanking the repeat region.

Detecting Marine Hazardous Substances And Organisms: Sensors For Pollutants, Toxins, And Pathogens, O. Zielinski, J. A. Busch, A. D. Cembella, Kendra L. Daly, J. Engelbrektsson, A. K. Hannides, H. Schmidt

Marine Science Faculty Publications

Marine environments are influenced by a wide diversity of anthropogenic and natural substances and organisms that may have adverse effects on human health and ecosystems. Real-time measurements of pollutants, toxins, and pathogens across a range of spatial scales are required to adequately monitor these hazards, manage the consequences, and to understand the processes governing their magnitude and distribution. Significant technological advancements have been made in recent years for the detection and analysis of such marine hazards. In particular, sensors deployed on a variety of mobile and fixed-point observing platforms provide a valuable means to assess hazards. In this review, we …

Integrative Clustering Of Multiple Genomic Data Types Using A Joint Latent Variable Model With Application To Breast And Lung Cancer Subtype Analysis, Ronglai Shen, Adam Olshen, Marc Ladanyi

Memorial Sloan-Kettering Cancer Center, Dept. of Epidemiology & Biostatistics Working Paper Series

The molecular complexity of a tumor manifests itself at the genomic, epigenomic, transcriptomic, and proteomic levels. Genomic profiling at these multiple levels should allow an integrated characterization of tumor etiology. However, there is a shortage of effective statistical and bioinformatic tools for truly integrative data analysis. The standard approach to integrative clustering is separate clustering followed by manual integration. A more statistically powerful approach would incorporate all data types simultaneously and generate a single integrated cluster assignment. We developed a joint latent variable model for integrative clustering. We call the resulting methodology iCluster. iCluster incorporates flexible modeling of the associations …

Model-Based Quality Assessment And Base-Calling For Second-Generation Sequencing Data, Rafael A. Irizarry, Hector Corrada Bravo

Johns Hopkins University, Dept. of Biostatistics Working Papers

Second-generation sequencing (sec-gen) technology can sequence millions of short fragments of DNA in parallel, and is capable of assembling complex genomes for a small fraction of the price and time of previous technologies. In fact, a recently formed international consortium, the 1,000 Genomes Project, plans to fully sequence the genomes of approximately 1,200 people. The prospect of comparative analysis at the sequence level of a large number of samples across multiple populations may be achieved within the next five years. These data present unprecedented challenges in statistical analysis. For instance, analysis operates on millions of short nucleotide sequences, or reads—strings …

Impairments In Attention In Occasionally Snoring Children: An Event-Related Potential Study., Maria E. Barnes, Elizabeth A. Huss, Krista N. Garrod, Eric Van Ray, Ehab Dayyat, David Gozal, Dennis L. Molfese

Faculty and Staff Scholarship

Objective: To determine whether minimal snoring is benign in children. Procedure: 22 rarely snoring children (mean age = 6.9 years, 11 females) and age- and sex-matched controls participated in an auditory oddball task wearing 128-electrode nets. Parents completed the Conners Parent Rating Scales–Revised Long (CPRS–R:L). Results: Snorers scored significantly higher on four CPRS-R:L subscales. Stepwise regression indicated that two ERP variables from a region of the ERP that peaked at 844 msec post-stimulus onset predicted CPRS-R:L Attention Deficit Hyperactivity Disorder (ADHD) Index scores. Conclusions: Occasional snorers, according to parental report, do exhibit ADHD-like behaviors. Basic sensory processing is longer than …

Genetic Population Structure Analysis In New Hampshire Reveals Eastern European Ancestry, Chantel D. Sloan, Angeline D. Andrew, Eric J. Duell, Scott M. Williams, Margaret R. Karagas, Jason H. Moore

Dartmouth Scholarship

Genetic structure due to ancestry has been well documented among many divergent human populations. However, the ability to associate ancestry with genetic substructure without using supervised clustering has not been explored in more presumably homogeneous and admixed US populations. The goal of this study was to determine if genetic structure could be detected in a United States population from a single state where the individuals have mixed European ancestry. Using Bayesian clustering with a set of 960 single nucleotide polymorphisms (SNPs) we found evidence of population stratification in 864 individuals from New Hampshire that can be used to differentiate the …

Tropical Dry Forest Succession And The Contribution Of Lianas To Wood Area Index (Wai), Arturo Sanchez-Azofeifa, Margaret Kalacska, Mario Marcos Do Espirito-Santo, G. Wilson Fernandes, Stefan A. Schnitzer

Biological Sciences Faculty Research and Publications

The transmission and interception of light through the canopy is an important indicator of forest productivity in tropical forest ecosystems, and the amount of light that eventually reaches the forest floor is influenced by its interactions with leaves, branches, fruits, and flowers among many different canopy elements. While most studies of forest canopy light interception focus on leaf area index (LAI), very few studies have examined wood area index (WAI), which may account for a substantial component of light interception in tropical forests. The influence of lianas on the interception of light and their overall contribution to WAI is a …

Broad Range Amino Acid Specificity Of Rna-Dependent Lipid Remodelling By Multiple Peptide Resistance Factors, Hervé Roy, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Aminoacylphosphatidylglycerol synthases (aaPGSs) are multiple peptide resistance factors that transfer amino acids from aminoacyl-tRNAs to phosphatidylglycerol (PG) in the cytoplasmic membrane. Aminoacylation of PG is used by bacteria to decrease the net negative charge of the cell envelope, diminishing affinity for charged molecules and allowing for adaptation to environmental changes. Lys-PGS, which transfers lysine to PG, is essential for the virulence of certain pathogens, providing resistance to both host cationic antimicrobial peptides and therapeutic antibiotics. Ala-PGS was also recently described, but little is known about the possible activities of other members of the highly diverse aaPGS family of proteins. Systematic …

Large-Scale Patterns In Trematode Richness And Infection Levels In Marine Crustacean Hosts, David W. Thieltges, Brian L. Fredensborg, Anja Studer, Robert Poulin

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Little is known about the patterns of variation in parasitism in marine hosts. Trematodes, the dominant parasites in intertidal systems, are transmitted from their first intermediate hosts (snails) to a range of second intermediate hosts, including crustaceans. Using published studies of trematode infections in crustacean hosts, we investigated general patterns of variation in trematode species richness and infection levels (i.e. percentage of hosts infected and mean number of individual parasites per host). Since the production and release of infective stages in snails is strongly temperature dependent, we also investigated a potential decrease in trematode infection levels with increasing latitude (as …

Reptilian Heart Development And The Molecular Basis Of Cardiac Chamber Evolution, K. Koshiba-Takeuchi, A. D. Mori, B. L. Kaynak, J. A. Cebra-Thomas, T. Sukonnik, R. O. Georges, S. Latham, L. Beck, R.

Biology Faculty Works

The emergence of terrestrial life witnessed the need for more sophisticated circulatory systems. This has evolved in birds, mammals and crocodilians into complete septation of the heart into left and right sides, allowing separate pulmonary and systemic circulatory systems, a key requirement for the evolution of endothermy(1-3). However, the evolution of the amniote heart is poorly understood. Reptilian hearts have been the subject of debate in the context of the evolution of cardiac septation: do they possess a single ventricular chamber or two incompletely septated ventricles(4-7)? Here we examine heart development in the red-eared slider turtle, Trachemys scripta elegans (a …

Geographical Patterning Of Sixteen Goat Breeds From Italy, Albania And Greece Assessed By Single Nucleotide Polymorphisms, Lorraine Pariset, Antonella Cuteri, Christina Ligda, Alessio Valentini, Econogene Consortium

Biological Sciences Faculty Publications

Background: SNP data of goats of three Mediterranean countries were used for population studies and reconstruction of geographical patterning. 496 individuals belonging to Italian, Albanian and Greek breeds were genotyped to assess the basic population parameters.

Results: A total of 26 SNPs were used, for a total of 12,896 genotypes assayed. Statistical analysis revealed that breeds are not so similar in terms of genetic variability, as reported in studies performed using different markers. The Mantel test showed a strongly significant correlation between genetic and geographic distance. Also, PCA analysis revealed that breeds are grouped according to geographical origin, …

Rumen Fermentation Pattern Of Dairy Heifers Fed Restricted Amounts Of Low, Medium, And High Concentrate Diets Without And With Yeast Culture, G. J. Lascano, A. J. Heinrichs

Dairy Science

Restricted feeding and highconcentratediets are potential strategies for growing dairyheifers. Ruminal manipulation with additives such as Saccharomyces cerevisiaeyeastculture (YC) has been shown to alter digestibility when added to this type of diet. An experiment was conducted to investigate the ruminal fermentation and in situ digestibility of diets with 3 different levels of forage to concentrate (F:C) fed at restricted intake without and with YC addition. Three cannulated post-pubertal Holstein heifers (age 18.0 ± 1.2 months; body weight 449.6 ± 19.7 kg) were feddiets consisting of corn silage as the sole forage source in a 3 period (35-day) Latin square …

Spatial And Seasonal Variations In Mercury Methylation And Microbial Community Structure In A Historic Mercury Mining Area, Yolo County, California, J. M. Holloway, M. B. Goldhaber, K. M. Scow, Rebecca E. Drenovsky

Biology

The relationships between soil parent lithology, nutrient concentrations, microbial biomass and community structure were evaluated in soils from a small watershed impacted by historic Hg mining. Upland and wetland soils, stream sediments and tailings were collected and analyzed for nutrients (DOC, SO4=, NO3−), Hg, MeHg, and phospholipid fatty acids (PLFA). Stream sediment was derived from serpentinite, siltstone, volcanic rocks and mineralized serpentine with cinnabar, metacinnabar and other Hg phases. Soils from different parent materials had distinct PLFA biomass and community structures that are related to nutrient concentrations and toxicity effects of trace metals including Hg. The formation of MeHg appears …

Making Biomass Pay: Obstacles And Opportunities, Gail Wells

Joint Fire Science Program Digests

Removing hazardous fuels to reduce the risk of wildfire has become a priority for land managers across the United States. Utilizing biomass taken from forests to cover the cost of fuel reduction is an attractive ideal. Effective utilization could also address important national challenges such as improving forest health, increasing domestic energy supplies, reducing carbon emissions, and revitalizing rural economies. However, getting woody biomass from the forest to the consumer is economically and logistically difficult, and efforts to make biomass utilization profitable have been disappointing so far. JFSP-funded researchers have found that, while there is no recipe for building a …

A Hump-Shaped Relationship Between Isolation And Abundance Of Notonecta Irrorata Colonists In Aquatic Mesocosms, Shannon J. Mccauley, Christopher J. Davis, Jennifer Nystrom, Earl E. Werner

Biological Sciences

We examined the relationship between the isolation of experimental aquatic mesocosms and the abundance of an aquatic insect colonist, Notonecta irrorata, over two years. We used a curve-fitting approach to assess whether linear or quadratic models better describe the relationship between isolation and abundance. For two measures of mesocosm isolation, distance to nearest source and distance to the largest source population, there was a significant quadratic relationship between isolation and abundance. Abundance of colonizing N. irrorata was not found to be significantly related to a third measure of isolation, mesocosm connectivity. These results indicate that the relationship between habitat …

Response To Displaced Neighbours In A Territorial Songbird With A Large Repertoire, Elodie F. Briefer, Thierry Aubin, Fanny Rybak

Ethology Collection

Neighbour recognition allows territory owners to modulate their territorial response according to the threat posed by each neighbour and thus to reduce the costs associated with territorial defence. Individual acoustic recognition of neighbours has been shown in numerous bird species, but few of them had a large repertoire. Here, we tested individual vocal recognition in a songbird with a large repertoire, the skylark Alauda arvensis. We first examined the physical basis for recognition in the song, and we then experimentally tested recognition by playing back songs of adjacent neighbours and strangers. Males showed a lower territorial response to adjacent neighbours …

The Scher Report On Non-Human Primate Research — Biased And Deeply Flawed, Jarrod Bailey, Katy Taylor

Experimentation Collection

The European Commission’s Scientific Committee on Health and Environmental Risks (SCHER) recently issued an Opinion on the need for non-human primate (NHP) use in biomedical research, and the possibilities of replacing NHP use with alternatives, as part of the Directive 86/609/EEC revision process. Here, we summarise our recent complaint to the European Ombudsman about SCHER’s Opinion and the entire consultation process. It is our opinion that the Working Group almost entirely failed to address its remit, and that the Group was unbalanced and contained insufficient expertise. The Opinion presumed the validity of NHP research with inadequate supporting evidence, and ignored …

An Examination Of Chimpanzee Use In Human Cancer Research, Jarrod Bailey

Laboratory Experiments Collection

Advocates of chimpanzee research claim the genetic similarity of humans and chimpanzees make them an indispensable research tool to combat human diseases. Given that cancer is a leading cause of human death worldwide, one might expect that if chimpanzees were needed for, or were productive in, cancer research, then they would have been widely used. This comprehensive literature analysis reveals that chimpanzees have scarcely been used in any form of cancer research, and that chimpanzee tumours are extremely rare and biologically different from human cancers. Often, chimpanzee citations described peripheral use of chimpanzee cells and genetic material in predominantly human …

Automatic Recognition Of Frog Calls Using A Multi-Stage Average Spectrum, Wen-Ping Chen, Song-Shyong Chen, Chun-Cheng Lin, Ya-Zhung Chen, Wen-Chih Lin

Bioacoustics Collection

The automatic recognition of animal sounds is one of the powerful techniques for replacing the traditional ecological survey method that mainly depends on manpower, which is hence both costly and time consuming. This study developed an automatic frog call recognition system based on the combination of a pre-classification method of the syllable lengths and a multi-stage average spectrum (MSAS) method. In this system, the input frog syllables are first classified into one of the four groups determined by the pre-classification method according to syllable length. Then the proposed MSAS method is used to extract the standard feature template to analyze …
