  1. 1. Experimental Evolution of Life-history : Testing the Evolutionary Theories of Ageing

    Author : Hwei-yen Chen; Alexei Maklakov; Tracey Chapman; Uppsala universitet; []
    Keywords : senescence; ageing; longevity; mortality; experimental evolution; Caenorhabditis remanei; Biologi; Biology;

    Abstract : Ageing reduces fitness, but how ageing evolves is still unclear. Evolutionary theory of ageing hinges on the fundamental principal that the force of natural selection declines with age. READ MORE

  2. 2. 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

  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

  4. 4. Age-specific trade-offs in life-history evolution

    Author : Martyna K. Zwoinska; Alexei Maklakov; Marjo Saastamoinen; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; life history; trade-off; learning; aging; sex differences; dispersal; Caenorhabditis; Drosophila; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : Trade-offs prevent selection from driving all fitness-enhancing traits towards values that would maximize fitness. Life-history trade-offs, such as the one between survival and reproduction are well-studied, yet trade-offs can also involve behavioural or cognitive traits. READ MORE
