  1. 1. Intraspecific diversity of pike (Esox lucius) in the Baltic Sea and new insights on thermoregulation in fish

    Författare :Oscar Nordahl; Per Larsson; Anders Forsman; Juha Merilä; Linnéuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; adaptive divergence; Cyprinus carpio; ecology; Esox lucius; evolution; local adaptation; management; thermoregulation; sun-basking; vertical migration; Akvatisk ekologi; Aquatic Ecology; Evolutionary Biology; Evolutionsbiologi;

    Sammanfattning : Fish display a fascinating variation in behavior, morphology and physiology among species, among individuals within species, and within individuals over time. A central quest in ecology and evolution is to understand causes and consequences of such variation. LÄS MER

  2. 2. Ecological drivers and genetic signatures of evolutionary divergence and local adaptation in pike (Esox lucius)

    Författare :Johanna Sunde; Anders Forsman; Anssi Laurila; Linnéuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; adaptation; differentiation; Esox lucius; evolution; gene flow; genetic admixture; genetic structure; microsatellites; pike; RADseq; salinity tolerance; temperature tolerance; Ecology; Ekologi;

    Sammanfattning : The diversity among species, populations, and individuals in nature is astonishing. Genetic and phenotypic variation constitutes the raw material for evolution. It influences how populations respond to changing environments, and can impact long-term survival of species and ecosystem functioning. LÄS MER

  3. 3. Population genetic patterns in continuous environments in relation to conservation management

    Författare :Lovisa Wennerström; Linda Laikre; Nils Ryman; Philip McGinnity; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Alces alces; Esox lucius; Multiple species; Baltic Sea; Conservation genetics; Microsatellites; Approximate Bayesian Computation; populationsgenetik; Population Genetics;

    Sammanfattning : Genetic variation is a prerequisite for the viability and evolution of species. Information on population genetic patterns on spatial and temporal scales is therefore important for effective management and for protection of biodiversity. LÄS MER

  4. 4. Effects of behavioural flexibility and habitat complexity on predator-prey interactions in fish communities

    Författare :Peter Eklöv; Gary G. Mittelbach; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; predator-prey interactions; behavioural flexibility; habitat complexity; foraging mode; sit-and-wait; group foraging; Perea fluviatilis; Esox lucius; Rutilus rutilus; size-structured interactions; species-specific antipredator behaviour; proximate cues; habitat distribution; temporal patterns;

  5. 5. Characterization of xenobiotic metabolism in the feral teleost northern pike (Esox lucius)

    Författare :Lennart Balk; Stockholms universitet; []

    Sammanfattning : A basic characterization of xenobiotic metabolism in the feral teleost Northern pike has been performed. The different aspects of concern have been:a) investigation of the uptake and distribution to different body compartments of the carcinogen and environmental pollutant benzo(a)pyrene using whole-body autoradiography and scintillation counting.
