  • Integrated Modelling of functional and structural connectivity of river corridors for european otter recovery
    Ecological Modelling, 2014
    Co-Authors: K Van Looy, Jeremy Piffady, Cyril Cavillon, Philippe Landry, Thierry Tormos, Yves Souchon
    Abstract:

    Abstract Connectivity may be structural , based on adjacency of landscape features, or functional , based on how that adjacency translates to movement of organisms. We present a Modelling approach that elucidates both aspects of connectivity to identify vital corridors and conservation priorities in a river network. For the dendritic network structure of river systems, at first a graph theoretic structure is developed to model the river network at the segment scale. To derive functional connectivity, a Bayesian hierarchical Modelling of species dispersal is applied to infer the influence of riparian corridor characteristics to the species colonization. The integration of the functional and structural component is realized with a graph-theoretic connectivity measure. With this approach, the European otter colonization of the Loire river basin over 25 years is modelled on the basis of large datasets on riparian corridor land use and hydromorphological characteristics of a 17,000 km river network. Channel straightening and riparian forest fragmentation are determined to be key elements to the functional connectivity. Road infrastructure is distinguished as a critical habitat factor, but not so much an obstacle for the species movement in the riparian corridor. Integration of the Bayesian model posterior colonization probability in the Integrated connectivity analysis reveals the importance of the river network density to the otter colonization and locates conservation priorities mainly in the lower parts of the river basin. Synthesis and applications Both functional and structural connectivity are essential elements in the contexts of ecological network identification for species conservation and recovery. We successfully developed an Integrated Modelling of both components of connectivity that highlighted the importance of the downstream basin for a well-connected ecological network for the otter.

  • Design and first applications of the ITER Integrated Modelling & analysis suite
    Nuclear Fusion, 2015
    Co-Authors: Frédéric Imbeaux, Simon Pinches, Jonathan Lister, Y. Buravand, Thomas Casper, Basil Duval, B. Guillerminet, Masanari Hosokawa, Wayne Houlberg, Philippe Huynh
    Abstract:

    The ITER Integrated Modelling & Analysis Suite (IMAS) will support both plasma operation and research activities on the ITER tokamak experiment. The IMAS will be accessible to all ITER members as a key tool for the scientific exploitation of ITER. The backbone of the IMAS infrastructure is a standardized, machine-generic data model that represents simulated and experimental data with identical structures. The other outcomes of the IMAS design and prototyping phase are a set of tools to access data and design Integrated Modelling workflows, as well as first plasma simulators workflows and components implemented with various degrees of modularity.

  • a generic data structure for Integrated Modelling of tokamak physics and subsystems
    Computer Physics Communications, 2010
    Co-Authors: Frédéric Imbeaux, D Coster, J B Lister, G T A Huysmans, W Zwingmann, M Airaj, L Appel, V Basiuk, Larsgoran Eriksson, B. Guillerminet
    Abstract:

    The European Integrated Tokamak Modelling Task Force (ITM-TF) is developing a new type of fully modular and flexible Integrated tokamak simulator, which will allow a large variety of simulation types. This ambitious goal requires new concepts of data structure and workflow organisation, which are described for the first time in this paper. The backbone of the system is a physics- and workflow-oriented data structure which allows for the deployment of a fully modular and flexible workflow organisation. The data structure is designed to be generic for any tokamak device and can be used to address physics simulation results, experimental data (including description of subsystem hardware) and engineering issues.
