  2. 1. Immunity & the butterfly : A functional genomic study of natural variation in immunity

    Author : Naomi L.P. Keehnen; Christopher W. Wheat; Brian Lazzaro; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; eco-immunology; functional genomics; transcriptomics; innate immunity; selection dynamics; melanization; phagocytosis; population genetics; Pieris napi; populationsgenetik; Population Genetics;

    Abstract : Butterflies are ubiquitous and abundant, occurring in a wide variety of environments that contain diverse microbial communities with varied pathogenic pressures. These pathogens and parasites present a constant threat to organisms, and have led to the evolution of complex and intricate immune responses. READ MORE

  4. 2. Geographic variation in life cycles : Local adaptation and ecological genetics in a temperate butterfly

    Author : Olle Lindestad; Karl Gotthard; Sören Nylin; Christopher W Wheat; Greg Ragland; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; voltinism; local adaptation; insect; life cycle; seasonality; genomics; life history; zoologisk ekologi; Animal Ecology;

    Abstract : Conditions in nature change with the seasons, necessitating seasonal adaptations that synchronize the life cycles of organisms with their surroundings. Such regulatory adaptations must vary between populations to track local variation in climate and seasonality; this local adaptation is facilitated by locally specific seasonal cues, but may be hampered by gene flow and genetic history.

  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
