Growth Increment Periodicity in the Shell of the Razor Clam Ensis Directus Using Stable Isotopes as a Method to Validate Age : Volume 10, Issue 3 (06/03/2013)

By: R. Witbaard; G. Nieuwland; H. W. Van Der Veer; J. P. MacHado; J. F. M. F. Cardoso

Description: NIOZ – Royal Netherlands Institute for Sea Research, P.O. Box 59, 1790 AB Den Burg Texel, the Netherlands. To evaluate the role of the razor clam Ensis directus in Dutch coastal waters, assessment and understanding its population dynamics is important. As such, the age structure of the population forms a key parameter. Accurate age determination in bivalve shells is not always straightforward due to the difficulty of interpreting externally visible growth lines. In the present paper, we aimed at validating the seasonality in growth line formation using visual techniques in combination with stable oxygen and carbon isotope analyses (Δ18O and Δ13C).

High Δ18O values in the shell coincided with growth marks on the external surface of the valve and in acetate peels of the shell's cross section. Most shell Δ18O samples were assigned to the months June to September. From November to March no samples were retrieved indicating that the shell did not grow. The lowest reconstructed temperature (6.1 °C) suggests that ~6 °C may be the threshold temperature fo...

Coincident Measurements of Pmse and Nlc Above Alomar (69° N, 16° E) by Radar and Lidar from 1999–2008 : Volume 10, Issue 10 (26/10/2010)

By: G. Baumgarten; R. Latteck; J. Fiedler; M. Rapp; N. Kaifler; F.-j. Lübken

Description: Leibniz Institute of Atmospheric Physics at the Rostock University, Kühlungsborn, Germany. Polar Mesosphere Summer Echoes (PMSE) and Noctilucent Clouds (NLC) have been routinely measured at the ALOMAR research facility in Northern Norway (69° N, 16° E) by lidar and radar, respectively. 2900 h of lidar measurements by the ALOMAR Rayleigh/Mie/Raman lidar were combined with almost 18 000 h of radar measurements by the ALWIN VHF radar, all taken during the years 1999 to 2008, to study simultaneous and common-volume observations of both phenomena. PMSE and NLC are known from both theory and observations to be positively linked. We quantify the occurrences of PMSE and/or NLC and relations in altitude, especially with respect to the lower layer boundaries. The PMSE occurrence rate is with 75.3% considerably higher than the NLC occurrence rate of 19.5%. For overlapping PMSE and NLC observations, we confirm the coincidence of the lower boundaries and find a standard deviation of 1.26 km, hinting at very fast sublimation rates. However, 10.1% of all NLC measureme...

Effects of Relative Humidity on Aerosol Light Scattering in the Arctic : Volume 10, Issue 2 (09/02/2010)

By: R. Fierz-schmidhauser; J. Ström; M. Gysel; K. E. Yttri; S. Henne; P. Zieger; U. Baltensperger; E. Weingartner

Description: Paul Scherrer Institut, Laboratory of Atmospheric Chemistry, 5232 Villigen, Switzerland. Aerosol particles experience hygroscopic growth in the ambient atmosphere. Their optical properties – especially the aerosol light scattering – are therefore strongly dependent on the ambient relative humidity (RH). In-situ light scattering measurements of long-term observations are usually performed under dry conditions (RH<30–40%). The knowledge of this RH effect is of eminent importance for climate forcing calculations or for the comparison of remote sensing with in-situ measurements. This study combines measurements and model calculations to describe the RH effect on aerosol light scattering for the first time of aerosol particles present in summer and fall at the high Arctic. For this purpose, a field campaign was carried out from July to October 2008 at the Zeppelin station in Ny-Ålesund, Svalbard. The aerosol light scattering coefficient Σsp(Λ) was measured at three distinct wavelengths (λ=450, 550, and 700 nm) at dry and at various, predefined RH conditio...

Geomorphosite Assessment in Montesinho Natural Park (Portugal) : Volume 62, Issue 3 (30/11/-0001)

By: D. Pereira; P. Pereira; M. I. Caetano Alves

Description: Earth Sciences Centre, Campus de Gualtar, University of Minho, 4710-057 Braga, Portugal. The Montesinho Natural Park (MNP), with an area of about 750 km2, is one of the largest protected areas in Portugal. Since its inauguration as a natural park in 1979, geological and geomorphological aspects have not been taken into consideration in its nature conservation policies. Over the last few years, this deficit has been compensated with an assessment of its geomorphological heritage. The assessment was made possible due to a research project on the geological heritage of the natural parks of north-eastern Portugal.The assessment method propagated herein proposes a clear definition of three types of geomorphosites: Single places, geomorphological areas or panoramic viewpoints. Further, it proposes as two-staged approach to assessment with inventory compilation followed by quantification of value. Inventory compilation, for example, involves the identification and qualitative assessment of potential geomorphosites and, therefore, the selection and characterization of geomorphosites. The quantification sta...

Plos Genetics : Gwas of Follicular Lymphoma Reveals Allelic Heterogeneity at 6P21.32 and Suggests Shared Genetic Susceptibility with Diffuse Large B-cell Lymphoma, Volume 7

By: Greg Gibson

Description : Non-Hodgkin lymphoma (NHL) represents a diverse group of hematological malignancies, of which follicular lymphoma (FL) is a prevalent subtype. A previous genome-wide association study has established a marker, rs10484561 in the human leukocyte antigen (HLA) class II region on 6p21.32 associated with increased FL risk. Here, in a three-stage genome-wide association study, starting with a genome-wide scan of 379 FL cases and 791 controls followed by validation in 1,049 cases and 5,790 controls, we identified a second independent FL–associated locus on 6p21.32, rs2647012 (ORcombined = 0.64, Pcombined=2610221) located 962 bp away from rs10484561 (r2,0.1 in controls). After mutual adjustment, the associations at the two SNPs remained genome-wide significant (rs2647012:ORadjusted = 0.70, Padjusted=4610212: rs10484561:ORadjusted = 1.64, Padjusted=5610215). Haplotype and coalescence analyses indicated that rs2647012 arose on an evolutionarily distinct haplotype from that of rs10484561 and tags a novel allele with an opposite (protective) effect on FL risk. Moreover, in a follow-up analysis of the top 6 FL–associated SNPs in 4,...

A Method to Correct Sampling Ghosts in Historic Near-infrared Fourier Transform Spectrometer (Fts) Measurements : Volume 6, Issue 2 (12/04/2013)

By: V. Sherlock; F. Hase; M. Gisi; E. Sepúlveda; S. Dohe; J. Robinson; M. Schneider; T. Blumenstock

Description: Karlsruhe Institute of Technology, Institute for Meteorology and Climate Research (IMK-ASF), Karlsruhe, Germany. The Total Carbon Column Observing Network (TCCON) has been established to provide ground-based remote sensing measurements of the column-average dry air mole fractions of key greenhouse gases. To ensure the network wide consistency, biases between Fourier Transform spectrometers at different sites have to be well controlled. In this study we investigate a fundamental correction scheme for errors in the sampling of the interferogram. This is a two-step procedure in which the laser sampling error (LSE) is quantified using a subset of suitable interferograms and then used to resample all the interferograms in the timeseries. Timeseries of measurements acquired at the TCCON sites Izaña and Lauder are used to demonstrate the method. At both sites the sampling error histories show changes in LSE due to instrument interventions. Estimated LSE are in good agreement with sampling errors inferred from lamp measurements of the ghost to parent ratio (Lauder). The LSE introduce retrieval biases which are mini...

Plos One : Soma ; a Single Oligonucleotide Mutagenesis and Cloning Approach, Volume 8

By: Hector Candela

Description : Modern biology research requires simple techniques for efficient and restriction site-independent modification of genetic material. Classical cloning and mutagenesis strategies are limited by their dependency on restriction sites and the use of complementary primer pairs. Here, we describe the Single Oligonucleotide Mutagenesis and Cloning Approach (SOMA) that is independent of restriction sites and only requires a single mutagenic oligonucleotide to modify a plasmid. We demonstrate the broad application spectrum of SOMA with three examples. First, we present a novel plasmid that in a standardized and rapid fashion can be used as a template for SOMA to generate GFP-reporters. We successfully use such a reporter to assess the in vivo knock-down quality of morpholinos in Xenopus laevis embryos. In a second example, we show how to use a SOMA-based protocol for restriction-site independent cloning to generate chimeric proteins by domain swapping between the two human hRMD5a and hRMD5b isoforms. Last, we show that SOMA simplifies the generation of randomized single-site mutagenized gene libraries. As an example we random-mu...

Journal of the American Geographical and Statistical Society : 2012 April No. 2 Vol. 30

By: Peter Arcidiacono

Description : The American Geographical Society (AGS) is an organization of professional geographers, founded in 1851 in New York City. Most fellows of the society are Americans, but among them have always been a significant number of fellows from around the world. The Society encourages activities that expand geographical knowledge, and presents and interprets that knowledge so that it can be understood and used not just by geographers but by others as well, especially policy makers. It is the oldest[1] nationwide geographical organization in the United States. Over the century and a half of its existence, the AGS has been especially interested in three regions : the Arctic, the Antarctic, and Latin America. A signature characteristic of the AGS-sponsored exploration was the requirement that its expeditions produce tangible scientific results....
