The National Science and Technology Council President Clinton established the National Science and Technology Council (NSTC) by Executive Order on November 23, 1993. This cabinet-level council is the principal means for the President to coordinate science, space, and technology policies across the federal government. The NSTC acts as a “virtual” agency for science and technology to coordinate the diverse parts of the federal research and development enterprise. The NSTC is chaired by the President. Membership consists of the Vice President, Assistant to the President for Science and Technology, cabinet secretaries and agency heads with significant science and technology responsibilities, and other White House officials. An important objective of the NSTC is to establish clear national goals for federal science and technology investments in areas ranging from information technologies, environment and natural resources, and health research, to improving transportation systems and strengthening fundamental research. The NSTC prepares research and development strategies that are coordinate across federal agencies to form an investment package that is aimed at accomplishing multiple national goals. To obtain additional information regarding the NSTC, contact the NSTC Executive Secretariat at 202-456-6100. The Committee on Environment and Natural Resources The Committee on Environment and Natural Resources (CENR) is one of five committees under the NSTC. It is charged with improving coordination among federal agencies involved in environmental and natural resources research and development, establishing a strong link between science and policy, and developing a federal environment and natural resources research and development strategy that responds to national and international issues. To obtain additional information regarding the CENR, contact the CENR executive secretariat at (202) 482-5916.

In oligotrophic oceans, diatom–diazotroph associations (DDAs) play a keystone role in ecosystem function because diazotrophs can provide otherwise scarce biologically available nitrogen to the diatom host, fueling growth and subsequent carbon sequestration. Despite their importance, relatively little is known about the nature of these associations in situ. Here we used metatranscriptomic sequencing of surface samples from the North Pacific Subtropical Gyre (NPSG) to reconstruct patterns of gene expression for the diazotrophic symbiont Richelia and we – 1234567890();,: 1234567890();,: examined how these patterns were integrated with those of the diatom host over day night transitions. Richelia exhibited significant diel signals for genes related to photosynthesis, N2 fixation, and resource acquisition, among other processes. N2 fixation genes were significantly co-expressed with host nitrogen uptake and metabolism, as well as potential genes involved in carbon transport, which may underpin the exchange of nitrogen and carbon within this association. Patterns of expression suggested cell division was integrated between the host and symbiont across the diel cycle.

These guanidinium groups confer high biological activity with high affinity and ion flux blockage capacity for voltage-gated sodium channels (NaV). Members of the STX group, known collectively as paralytic shellfish toxins (PSTs), are produced among three genera of marine dinoflagellates and about a dozen genera of primarily freshwater or brackish water cyanobacteria. In contrast, toxins of the TTX group occur mainly in macrozoa, particularly among puffer fish, several species of marine invertebrates and a few terrestrial amphibians. In the case of TTX and analogs, most evidence suggests that symbiotic bacteria are the origin of the toxins, although endogenous biosynthesis independent from bacteria has not been excluded. The evolutionary origin of the biosynthetic genes for STX and analogs in dinoflagellates and cyanobacteria remains elusive. These highly potent molecules have been the subject of intensive research since the latter half of the past century; first to study the mode of action of their toxigenicity, and later as tools to characterize the role and structure of NaV channels, and finally as therapeutics.

University of Trondheim, Bynesvn. 46, N-7018 Trondheim, Norway ABSTRACT: Some of the principles governing phytoplankton growth, biomass, and species composi- tion in 2-layered pelagic ecosystems are explored using an idealized, steady-state, mathematical model, based on simple extensions of Lotka-Volterra type equations. In particular, the properties of a food web based on 'small' and 'large' phytoplankton are investigated. Features of the phytoplankton community that may be derived from this conceptually simple model include CO-existenceof more than one species on one limiting nutrient, a rapid growth rate for a large fraction of the phytoplankton community in oligotrophic waters, a long food chain starting from a population of small phytoplankton in waters with moderate mixing over the nutricline, and a transition to dominance of a food chain based on large phytoplankton when mixing is increased. As pointed out by other authors, careless use of the concept of one limiting factor may be potentially confusing in such systems. To avoid this, a distinction in terminology between 'controlling' and 'limiting' factors is suggested. INTRODUCTION dominance of short food chains in upwelling areas (Ryther 1969).

  • Development and Validation of a Novel Approach for the Analysis of Marine Biotoxins

    Development and Validation of a Novel Approach for the Analysis of Marine Biotoxins

    DEVELOPMENT AND VALIDATION OF A NOVEL APPROACH FOR THE ANALYSIS OF MARINE BIOTOXINS Bing Cheng Chai College of Engineering and Science Victoria University Submitted in fulfilment of the requirements of the degree of Doctor of Philosophy June 2017 ABSTRACT Harmful algal blooms (HABs) which can produce a variety of marine biotoxins are a prevalent and growing risk to public safety. The aim of this research was to investigate, evaluate, develop and validate an analytical method for the detection and quantitation of five important groups of marine biotoxins in shellfish tissue. These groups included paralytic shellfish toxins (PST), amnesic shellfish toxins (AST), diarrheic shellfish toxins (DST), azaspiracids (AZA) and neurotoxic shellfish toxins (NST). A novel tandem liquid chromatographic (LC) approach using hydrophilic interaction chromatography (HILIC), aqueous normal phase (ANP), reversed phase (RP) chromatography, tandem mass spectrometry (MSMS) and fluorescence spectroscopic detection (FLD) was designed and tested. During method development of the tandem LC setup, it was found that HILIC and ANP columns were unsuitable for the PSTs because of the lack of chromatographic separation power, precluding them from being used with MSMS detection. In addition, sensitivity for the PSTs at regulatory limits could not be achieved with MSMS detection, which led to a RP-FLD combination. The technique of RP-MSMS was found to be suitable for the remaining four groups of biotoxins. The final method was a combination of two RP columns coupled with FLD and MSMS detectors, with a valve switching program and injection program. A novel sample preparation method was also developed for the extraction and clean-up of biotoxins from mussels.

Therefore, it should come as no surprise that when the genome of a eukaryote is sequenced, a medley of bacterial sequences are produced as well. These sequences can be highly informative about the interactions between the eukaryote and its bacterial cohorts; unfortunately, they often comprise a vanishingly small constituent within a heterogeneous mixture of microbial and host sequences. Genomic analyses typically avoid the bacterial sequences in order to obtain a genome sequence for the host. Metagenomic analysis typically avoid the host sequences in order to analyze community composition and functional diversity of the bacterial component. This dissertation describes the development of a novel approach at the intersection of genomics and metagenomics, aimed at the extraction and characterization of bacterial sequences from heterogeneous sequence data using phylogenomic and bioinformatic tools. To achieve this objective, three interoperable workflows were constructed as modular computational pipelines, with built-in checkpoints for periodic interpretation and refinement.
