  2. 6. The prey perspective - behaviour and appearance in a world of predators

    Author : Johan Ahlgren; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Local adaptation; predator regime; phenotypic plasticity; inducible defence; mortality; animal personality; predator; trait-compensation;

    Abstract : The varieties of prey phenotypes that have been revealed in nature are vast and many of these phenotypes are the result of the selective force that predators have had on prey traits in the past. Even within species and populations we see variations due to both differences in the selection forces they live under but also due to individual trait variation. READ MORE

  4. 7. Predator effects on behaviour and life-history of prey

    Author : Tomas Brodin; Frank Johansson; Bradley Anholt; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; activity; behaviour; behavioural syndromes; damselfly; development; growth; life-history; predator-prey interaction; predation risk; thinning; Freshwater ecology; Limnisk ekologi;

    Abstract : In this thesis I investigate predator-induced effects on behavioural and life-history characteristics of prey. At any moment a given predator is capable of attacking a small number of prey. READ MORE

  5. 8. Causes and consequences of individual variation in anti-predator traits

    Author : Kaj Hulthén; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal migration; partial migration; individual differences; predator; personality trait; phenotypic plasticity; inducible defence; mortality risk;

    Abstract : Predation imposes a potent evolutionary force on prey, moulding the evolution of traits and diversification of species, and can furthermore have powerful ecological consequences. We know that different species vary in how they cope with their natural enemies, and, consequently, a huge range of anti-predator defences are displayed in nature. READ MORE
