  2. 1. Cryptic Female Choice and Male Mating Behaviour : Sexual Interactions in Beetles

    Author : Martin Edvardsson; Göran Arnqvist; Paul Ward; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Cryptic female choice; Copulatory courtship; Harmful male traits; Nuptial gifts; Sperm competition; Sexual selection; Tribolium castaneum; Callosobruchus maculatus; Biologi; Biology; Biologi;

    Abstract : The importance of cryptic female choice, i.e. female post-copulatory influence over male reproductive success, in driving the evolution of male traits remains controversial. The main aim of this thesis was to understand the post-copulatory consequences of sexual interactions and the importance of cryptic female choice in two species of beetle. READ MORE

  4. 2. Choice, competition, and interactions between episodes of sexual selection

    Author : Charel Reuland; John Fitzpatrick; Ingo Schlupp; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; contest competition; sperm competition; mate choice; cryptic choice; sperm quality; reproductive status; social dominance; etologi; Ethology;

    Abstract : Choice and competition are essential parts of evolutionary biology. In an effort to pass their genes from one generation to the next, animals may carefully choose their mating partners, and/or compete for access to mates. READ MORE

  5. 3. Sexual conflict and male-female coevolution in the fruit fly

    Author : Urban Friberg; Göran Arnqvist; Daniel Promislow; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cryptic male mate choice; Drosophila melanogaster; female mate choice; multiple mating; sexual conflict; sexually antagonistic coevolution; sexual selection; speciation; sperm competition; Biology; Biologi;

    Abstract : Harmony and cooperation was for long believed to dominate sexual interactions. This view slowly started to change 25 years ago and is today replaced with a view where males and females act based on what is best from a costs-benefits perspective. READ MORE

  6. 4. Pre- and post-copulatory sexual selection in the fowl, Gallus gallus

    Author : Hanne Løvlie; Sven Jakobsson; Tommaso Pizzari; Matthew J. G. Gage; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cryptic female choice; Gallus; inbreeding avoidance; mate choice; sexual conflict; sexual selection; sperm competition; Ethology and behavioural ecology; Etologi och beteendeekologi; etologi; Ethology;

    Abstract : The evolutionary goal of individuals is reproduction and sexual selection favours traits improving reproductive success. When males invest less than females in offspring, males have potentially a higher reproductive rate than females. READ MORE

  7. 5. Polyandry and the evolution of reproductive divergence in insects

    Author : Tina Nilsson; Göran Arnqvist; David Hosken; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Bruchidae; cryptic female choice; multiple mating; sexual conflict; sexually antagonistic coevolution; sexual selection; speciation; sperm competition; Tenebrionidae; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : Multiple mating by females is common in nature. Yet, the evolution and maintenance of polyandry remains a bit of an evolutionary puzzle. It was my aim in this thesis to reach a greater understanding of this phenomenon as well as to investigate the consequences of polyandry on the evolution of reproductive divergence in insects.
