    Sammanfattning : The management and conservation of wildlife must rely on a solid understanding of key ecological and demographic factors. To devise management and conservation strategies for species affected by human activities it is essential to define populations. LÄS MER

    Sammanfattning :  ABSTRACT Migration is common among populations of brown trout (Salmo trutta) and Atlantic salmon (Salmo salar). However, not all individuals in the same population migrate, a phenomenon referred to as partial migration. LÄS MER

  4. 14. On the protective value of conspicuous eyespots in Lepidoptera

    Detta är en avhandling från Stockholm : Zoologiska institutionen

    Författare :Adrian Vallin; Stockholms universitet.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Ethology and behavioural ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi Etologi och beteendeekologi;

    Sammanfattning : Eyespots, circular patterns which resemble the general appearance of the vertebrate eye, are widespread throughout the animal kingdom and are for example, commonly found on the wings of butterflies where they have been proposed to confer protection against predation. However, empirical evidence of the adaptive value of eyespots, as well as knowledge of butterfly behaviour under the threat of predation, is scarce. LÄS MER
