    OSPAR threatened and/or declining species and habitats in the Netherlands

    In order to protect biodiversity, OSPAR has defined a list of ‘threatened and declining species and habitats’ that are in need of protection. This list is based upon nominations of species and habitats that were considered priorities for protection by Contracting Parties and observers to the Commission. In the past few years, for a number of species and habitats OSPAR recommendation have been adopted. Since the Dutch government has the obligation to take measures in accordance with the recommendations, an overview of the present occurrence, monitoring and measures was needed. In this report we provide summary sheets per species or habitat type, in which the distribution and trends of each species in the Dutch part of the OSPAR area is shown

    Een uitgebreide meetinspanning op de Noordzee, in combinatie met wiskundige en statistische modellering, laat zien dat de klimaatveranderingen in de vorm van een verandering in de overheersende windrichting, een toename van de windsnelheid, een toename van de zeewatertemperatuur, als wel als een toenemende CO2 concentratie van de atmosfeer, niet alleen leidt tot een verandering van de samenstelling van het zeewater in de vorm van bijvoorbeeld opgelost anorganisch koolstof en zuurgraad, maar ook tot een, zei het beperkte, verlaging van de productiviteit van op en in de zeebodem levende filterende organismen, die op hun beurt het voedsel zijn van bodembewonende vissen

    Universal scaling in highly doped conducting polymer films

    Get PDF
    Electrical transport of a highly doped disordered conducting polymer, viz. poly-3,4-ethylenedioxythiophene stabilized with poly-4-styrenesulphonic acid, is investigated as a function of bias and temperature. The transport shows universal power-law scaling with both bias and temperature. All measurements constitute a single universal curve, and the complete J(V,T) characteristics are described by a single equation. We relate this scaling to dissipative tunneling processes, such as Coulomb blockade. © 2010 The American Physical Society
