  1. 1. The genetic architecture of sexual dimorphism

    Author : Robert Griffin; Urban Friberg; Alexei Maklakov; Jon Ågren; Russell Bonduriansky; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; evolution; intralocus sexual conflict; sex chromosomes; sexually antagonistic selection; sexual dimorphism;

    Abstract : Phenotypic differences between the sexes evolve largely because selection favours a different complement of traits in either sex. Theory suggests that, despite its frequency, sexual dimorphism should be generally constrained from evolving because the sexes share much of their genome. READ MORE

  2. 2. The Evolution of Sexually Homologous Ornaments : Selection via Male Mate Choice Coinciding with Male-Male Competition in a Neotropical Mosquito

    Author : Sandra South; Göran Arnqvist; Russell Bonduriansky; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; sexual selection; Sabethes cyaneus; Diptera; Culicidae; mosquito; mutual ornamentation; sexual selection; mutual mate choice; male mate choice; female ornament; ecology; animal behaviour; Ethology and behavioural ecology; Etologi och beteendeekologi; Animal Ecology; Zooekologi;

    Abstract : The evolution of elaborate male ornaments via sexual selection is well-understood while the selective pressures acting on female ornaments remains unresolved. Female ornaments in species with strong sexual selection on the male homologue of the ornament were originally thought to result from an intersexual genetic correlation. READ MORE

  3. 3. Condition-dependence in life history evolution

    Author : Foteini Spagopoulou; Alexei Maklakov; Lars Gustafsson; Russell Bonduriansky; Pat Monaghan; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ageing; senescence; nongenetic inheritance; sex differences; condition-dependence; life history; trade-off; Ficedula albicollis; Caenorhabditis remanei; Telostylinus angusticollis; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : Ageing is the progressive physiological deterioration that appears with increasing age and eventually leads to a decline in survival and reproduction. This physiological process is omnipresent across the tree of life, but the expected trajectory can widely vary between and within species. READ MORE
