2. 1. A functional genomic investigation of an alternative life history strategy : The Alba polymorphism in Colias croceus

   Author : Alyssa Woronik; Christopher Wheat; Antonia Monteiro; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; alternative life history strategy; butterfly wing color; Alba; Colias; color polymorphism; dimorphism; life history traits; physiology; lipidomics; genomics; pooled sequencing; phylogenomics; RNA-Seq; Pool-Seq; populationsgenetik; Population Genetics;

   Abstract : Life history traits affect the timing and pattern of maturation, reproduction, and survival during an organism’s lifecycle and are the major components influencing Darwinian fitness. Co-evolved patterns of these traits are known as life history strategies (LHS) and variation occurs between individuals, populations, and species. READ MORE

4. 2. Templating and self-assembly of biomimetic materials

   Author : Christian Mille; Lennart Bergström; Mika Linden; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomimetic; biotemplating; self-assembly; triply periodic minimal surfaces; the gyroid; photonic crystals; band gap; structural color; chirality; butterflies; membrane proteins; lipid bilayers; sol-gel; mesostructured; polyhedral nanofoams; Materials Chemistry; materialkemi;

   Abstract : This thesis focuses on the use of biomolecular assemblies for creating materials with novel properties. Several aspects of biomimetic materials have been investigated, from fundamental studies on membrane shaping molecules to the integration of biomolecules with inorganic materials. READ MORE

5. 3. Understanding evolutionary novelty through female-limited polymorphisms

   Author : Kalle Tunström; Christopher W. Wheat; Rhonda R. Snook; Patrícia Beldade; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; populationsgenetik; Population Genetics;

   Abstract : Understanding how novel traits evolve is a central question in evolutionary biology. However, unraveling the complex genetic and developmental mechanisms underlying trait innovation can be challenging, especially when the trait evolved a long time ago. READ MORE

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

   Author : Baharan Kazemi; Olof Leimar; Gabriella Gamberale-Stille; Mike Speed; Stockholms universitet; []
   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
