  1. 1. Forest – stream linkages Brown trout (Salmo trutta) responses to woody debris, terrestrial invertebrates and light

    Detta är en avhandling från Karlstad : Karlstad University

    Författare :Pär Gustafsson; Eva Bergman; Larry Greenberg; Kurt Fausch; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Brown trout; growth; foraging; woody debris; terrestrial invertebrates; light; riparian zone; forestry; stream; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Freshwater ecology; NATURVETENSKAP Biologi Terrestrisk; limnisk och marin ekologi Limnisk ekologi; Biology; Biologi;

    Sammanfattning : Forests surrounding streams affect aquatic communities in numerous ways, contributing to energy fluxes between terrestrial and lotic ecosystems. The five papers in this thesis focus on woody debris, terrestrial invertebrates and light, three factors influenced by riparian zone structure, potentially affecting streams and brown trout (Salmo trutta).

  2. 2. Fine stream wood effects on drift and brown trout (Salmo trutta) growth and behaviour

    Detta är en avhandling från Karlstad University Press

    Författare :Åsa Enefalk; Eva Bergman; Anders Nilsson; Stanley Gregory; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stream fish; wood; salmonid; trout; aquatic invertebrates; behaviour; sheltering; Biology; Biologi;

    Sammanfattning : Stream ecosystems and their riparian zones have previously been regarded as two different ecosystems, linked through numerous reciprocal subsidies. Today, ecologists agree that the stream and the riparian zone should be regarded as one system, the stream-riparian ecosystem, which is characterised largely by the subsidies between land and water.

  3. 3. Scalable Scientific Stream Query Processing

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Milena Ivanova; Tore Risch; Elke A. Rundensteiner; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data stream management systems; parallel stream processing; scientific stream query processing; user-defined stream partitioning; TECHNOLOGY Information technology Computer science Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Datalogi; Data- och systemvetenskap; Computer Systems Sciences;

    Sammanfattning : Scientific applications require processing of high-volume on-line streams of numerical data from instruments and simulations. In order to extract information and detect interesting patterns in these streams scientists need to perform on-line analyses including advanced and often expensive numerical computations. LÄS MER

  4. 4. Forest-stream linkages Experimental studies of foraging and growth of brown trout (Salmo trutta L)

    Detta är en avhandling från Fakulteten för samhälls- och livsvetenskaper

    Författare :Pär Gustafsson; Eva Bergman; Larry Greenberg; John Armstrong; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Brown trout; diet; growth; riparian zone; forest-stream linkages; terrestrial invertebrates; light; primary production; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; Biology; Biologi;

    Sammanfattning : Riparian vegetation along streams and rivers affects the aquatic community in numerous ways and often operates as a link for energy flux between forest and streams. The studies presented in this licentiate thesis focus on light and terrestrial invertebrates, two factors influenced by riparian zone structure, which potentially affect stream ecosystems and thus also brown trout (Salmo trutta).

  5. 5. Distributed stream ciphers

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Magnus Öberg; Ben Smeets; [2003]

    Sammanfattning : Cryptographic operations are normally carried out by a single machine. Sometimes, however, this machine cannot be trusted completely. Threshold cryptography offers an alternative where the cryptographic operation is distributed to a group of machines in such a way that the key used in the cryptographic operation is not revealed to anyone.
