  1. 1. Migratory behaviour and adaptive divergence in life-history traits of pike (Esox lucius)

    Author : Petter Tibblin; Per Larsson; Anders Forsman; Asbjørn Vøllestad; Linnéuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; conservation; evolution; homing; local adaptation; management; phenotypic variation; population divergence; selection; sympatric;

    Abstract : Population divergence shaped by natural selection is central to evolutionary ecology research and has been in focus since Darwin formulated “The origin of species”. Still, the process of adaptive divergence among sympatric populations is poorly understood. READ MORE

  2. 2. Exploring mechanisms of sympatric speciation

    Keywords : ;

    Abstract : .... READ MORE

  3. 3. The role of Assortative Mating in the Initial Stages of Sympatric and Parapatric Speciation

    Author : Emma Rova; Mats Björklund; Göran Arnqvist; James Mallet; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Callosobruchus maculatus; host fidelity; assortative mating; inbreeding; experimental evidence; sympatric speciation; parapatric speciation; Biology; Biologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : Divergence in the face of gene flow is perhaps the most wildly disputed subject among researchers through time. The debate is an old one and we find its origin as far back as the era of Darwin. READ MORE

  4. 4. Artificial neural networks in models of specialization and sympatric speciation

    Author : Niclas Norrström; Högskolan i Skövde; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Biology; Biologi; Naturvetenskap; Natural sciences;

    Abstract : This thesis deals with specialization and how it is linked to sympatric speciation. The trait driving specialization is a cue recognition trait modelled with artificial neural networks that exploiters use to discriminate beneficial resources from detrimental resources based on the signals of the resources.
