  1. 1. Evolution of Mimicry and Aposematism Explained: Salient Traits and Predator Psychology

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Author : Baharan Kazemi; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; imperfect mimicry; mimicry evolution; predator learning; discrimination; generalization; salience; overshadowing; aposematism; warning signal evolution; generalization bias; peak shift; etologi; Ethology;

    Abstract : Aposematic species have evolved conspicuous warning signals, such as bright colors and striking patterns, to deter predators. Some edible and harmless species take advantage of this deterrent effect by mimicking their appearance. Mimicry is a great example of how natural selection produces remarkable adaptations. READ MORE
