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

    Författare :Baharan Kazemi; Olof Leimar; Gabriella Gamberale-Stille; Mike Speed; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; imperfect mimicry; mimicry evolution; predator learning; discrimination; generalization; salience; overshadowing; aposematism; warning signal evolution; generalization bias; peak shift; etologi; Ethology;

    Sammanfattning : 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. LÄS MER

  3. 2. Predator psychology and mimicry evolution - a theoretical analysis

    Författare :Alexandra Balogh; Olof Leimar; Michael Speed; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Müllerian mimicry; two-step evolution; gradual evolution; mutualism; predator psychology; Ethology and behavioural ecology; Etologi och beteendeekologi; etologi; Ethology;

    Sammanfattning : The evolution of Müllerian mimicry depends on many factors, among which predator psychology is the most important one. Predator avoidance learning, generalization and discrimination are primary selective agents during the evolutionary process. LÄS MER

  4. 3. Colour patterns in warning displays

    Författare :Marianne Aronsson; Gabriella Gamberale-Stille; Olof Leimar; Candy Rowe; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aposematism; warning colouration; colour patterns; avoidance learning; generalization behaviour; signal design; signal evolution; conspicuousness; mimicry; etologi; Ethology;

    Sammanfattning : In aposematism a prey species use bright colours, often combined with a black contrasting pattern, to signal unprofitability as prey to potential predators. Although there are several different hypotheses about the presence of these internally contrasting patterns, there is little experimental evidence of any beneficial effects. LÄS MER

  7. 5. Evolution and viral mimicry of short linear motif-mediated interactions

    Författare :Filip Mihalič; Per Jemth; Leo James; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phage display; protein-protein interactions; large-scale discovery; short linear motifs; viral mimcry; viral hijacking; Biokemi; Biochemistry; Medical Biochemistry; Medicinsk biokemi;

    Sammanfattning : Proteins are one of the most fundamental building blocks of life and their interactions regulate every cellular process. Historically they have been conceptualized as predominantly folded entities with well-defined secondary and tertiary structures. LÄS MER
