Isotopic Discrimination In The Double-Crested Cormorant (Phalacrocorax Auritus), Elizabeth C. Craig, Brian S. Dorr, Katie C. Hanson-Dorr, Jed P. Sparks, Paul D. Curtis

Brian S Dorr

The diet-tissue discrimination factor is the amount by which a consumer’s tissue varies isotopically from its diet, and is therefore a key element in models that use stable isotopes to estimate diet composition. In this study we measured discrimination factors in blood (whole blood, red blood cells and plasma), liver, muscle and feathers of Double- crested Cormorants (Phalacrocorax auritus) for stable isotope ratios of carbon, nitrogen and sulfur. Cormorants exhibited discrimination factors that differed significantly among tissue types (for carbon and nitrogen), and differed substantially (in the context of the isotopic variation among relevant prey species) from those observed in …


Satpdb: A Database Of Structurally Annotated Therapeutic Peptides, Sandeep Singh Oct 2015

Satpdb: A Database Of Structurally Annotated Therapeutic Peptides, Sandeep Singh

Sandeep Singh

SATPdb (http://crdd.osdd.net/raghava/satpdb/) is a database of structurally annotated therapeutic peptides, curated from 22 public domain peptide databases/datasets including 9 of our own. The current version holds 19192 unique experimentally validated therapeutic peptide sequences having length between 2 and 50 amino acids. It covers peptides having natural, non-natural and modified residues. These peptides were systematically grouped into 10 categories based on their major function or therapeutic property like 1099 anticancer, 10585 antimicrobial, 1642 drug delivery and 1698 antihypertensive peptides. We assigned or annotated structure of these therapeutic peptides using structural databases (Protein Data Bank) and state-of-the-art structure prediction methods like I-TASSER, …

Comparative Analysis Of Biodegradability Of Biodiesel Obtained By Conventional And Non-Conventional Methods, Innovative Research Publications Irp India, Nagaraja Y. P, Chandrashekhar Biradar Mar 2015

Comparative Analysis Of Biodegradability Of Biodiesel Obtained By Conventional And Non-Conventional Methods, Innovative Research Publications Irp India, Nagaraja Y. P, Chandrashekhar Biradar

Biodiesel is an alternative to conventional diesel fuel made from renewable resources. No engine modifications are required to use biodiesel in place of crude oil-based diesel. The use of biodiesel resulted in lower emissions of unburned hydrocarbons, carbon monoxide and particulate matter. Biodiesel also increased catalytic converter efficiency in reducing particulate emissions. Chemical characterization also revealed lower levels of some toxic and reactive hydrocarbon species when biodiesel fuels were used. In the present work, biodiesel is produced by both conventional and non-conventional methods to determine the biodegradability effect using microorganisms obtained from soil collected from the vicinity of a petrol …


Production And Purification Of Tannase From Aspergillus Aculeatus Using Plant Derived Raw Tannin, Innovative Research Publications Irp India, Jasbir Bagga, Soumya Kanti Pramanik, Vibha Pandey Feb 2015

Production And Purification Of Tannase From Aspergillus Aculeatus Using Plant Derived Raw Tannin, Innovative Research Publications Irp India, Jasbir Bagga, Soumya Kanti Pramanik, Vibha Pandey

Innovative Research Publications IRP India

Tannase, an enzyme with immense potential has lot of applications in food, beverage, pharmaceutical and chemical industries. During the present study, tannin content of different plant materials was determined. Tannase has been produced from Aspergillus aculeatus through fermentation of tannin rich plant materials. Among the plant materials used, Cassia ciamia gives better result. Maximum oxygen is utilized by the organism after 24 h of growth. pH of the fermented broth falls to 4.1 after 28 h of growth. Organism utilizes wheat bran as a solid substrate to produce maximum tannase. Maximum enzyme production through solid state fermentation was achieved after …


Social Science Contributions Compared In Synthetic Biology And Nanotechnology, Philip Shapira, Jan Youtie, Yin Li Feb 2015

Social Science Contributions Compared In Synthetic Biology And Nanotechnology, Philip Shapira, Jan Youtie, Yin Li

Philip Shapira

With growing attention to societal issues and implications of synthetic biology, we investigate sources of social science publication knowledge in synthetic biology and probe what might be learned by comparison with earlier rounds of social science research in nanotechnology. “Social science” research is broadly defined to include publications in conventional social science as well as humanities, law, ethics, business, and policy fields. We examine the knowledge clusters underpinning social science publications in nanotechnology and synthetic biology using a methodology based on the analysis of cited references. Our analysis finds that social science research in synthetic biology already has traction and …


Annual Variation In Autumn Migration Phenology And Energetic Condition At A Stopover Site In The Western United States, Robert A. Miller, Jay D. Carlisle, Neil Paprocki, Gregory S. Kaltenecker, Julie A. Heath Jan 2015

Annual Variation In Autumn Migration Phenology And Energetic Condition At A Stopover Site In The Western United States, Robert A. Miller, Jay D. Carlisle, Neil Paprocki, Gregory S. Kaltenecker, Julie A. Heath

Robert Miller

Climate change is having a dramatic effect on many migratory species. Changes in climate may lead to changes in food availability or other proximate cues that affect migratory behavior. We used 13 years (2000–2012) of data on songbird banding and raptor migration counts and captures during autumn migration in the intermountain West to evaluate whether regional temperature or precipitation or hemispheric climate indices predicted autumn migratory timing and energetic condition. We examined overall trends and evaluated the effects of diet and migratory distance on phenology and conditional responses. For the 13-year study period, no temperature, precipitation, or climate index trends …


Importance Of Genetic Diversity Assessment In Crop Plants And Its Recent Advances: An Overview Of Its Analytical Perspectives, Mahalingam Govindaraj Jan 2015

Importance Of Genetic Diversity Assessment In Crop Plants And Its Recent Advances: An Overview Of Its Analytical Perspectives, Mahalingam Govindaraj

The importance of plant genetic diversity (PGD) is now being recognized as a specific area since exploding population with urbanization and decreasing cultivable lands are the critical factors contributing to food insecurity in developing world.Agricultural scientists realized that PGD can be captured and stored in the formof plant genetic resources (PGR) such as gene bank,DNA library, and so forth, in the biorepository which preserve genetic material for long period. However, conserved PGR must be utilized for crop improvement in order to meet future global challenges in relation to food and nutritional security.This paper comprehensively reviews four important areas; (i) the …

Warm Microhabitats Drive Both Increased Respiration And Growth Rates Of Intertidal Consumers, Luke P. Miller, Bengt J. Allen, Felicia A. King, Daisy R. Chilin, Vanessa M. Reynoso, Mark W. Denny Jan 2015

Warm Microhabitats Drive Both Increased Respiration And Growth Rates Of Intertidal Consumers, Luke P. Miller, Bengt J. Allen, Felicia A. King, Daisy R. Chilin, Vanessa M. Reynoso, Mark W. Denny

Luke P. Miller

Rocky intertidal organisms are often exposed to broadly fluctuating temperatures as the tides rise and fall. Many mobile consumers living on the shore are immobile during low tide, and can be exposed to high temperatures on calm, warm days. Rising body temperatures can raise metabolic rates, induce stress responses, and potentially affect growth and survival, but the effects may differ among species with different microhabitat preferences. We measured aerial and aquatic respiration rates of 4 species of Lottia limpets from central California, and estimated critical thermal maxima. In a variety of microhabitats in the field, we tracked body temperatures and …
