  2. 1. Living in a Variable Environment : Reproductive Decisions in Wild Bird Populations

    Author : Mårten B. Hjernquist; Lars Gustafsson; Marcel Visser; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolutionary ecology; competition; sex allocation; paternity; EPP; inadvertent social information; migration; breeding density; territory quality; territory availability; great tit; blue tit; Ficedula albicollis; Biology; Biologi; Animal Ecology; zooekologi;

    Abstract : In nature, environments are often variable and heterogeneous influencing ecological and evolutionary processes. This thesis focus on how animals interact with their environment and how that affects the reproductive decisions they make. READ MORE

  4. 2. Infidelity in Birds – Causes and Consequences of Extra-pair Paternity

    Author : Jakob Augustin; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; extra-pair paternity; genetic benefits; heterozygosity; sex ratio; Riparia riparia; Tringa totanus; Vanellus vanellus; Charadrius alexandrinus;

    Abstract : Forty years ago, more than 90% of bird species were classified as monogamous and not very exciting systems for studies of e.g. sexual selection. READ MORE

  5. 3. Genetic variation in natural populations: a modeller's perspective

    Author : Marina Rafajlovic; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coalescent process; site frequency spectrum; multiple paternity; dominant clone; divergent selection;

    Abstract : Thanks to advances in genome sequencing, empirical patterns of within- and between-species genetic variation are readily available. By studying these patterns much has been learned about the evolutionary histories of species. But the causes and consequences of different evolutionary histories are still difficult to tell apart.

  6. 4. Genetic variation in structured populations

    Author : Marina Rafajlovic; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; genetic variation; varying population size; effective population size; mutation; recombination; migration; multiple paternity; geographic structure; tests of neutrality; gene tree; species tree;

    Abstract : It is widely acknowledged that the process of speciation in the presence of gene flow between different ecotypes is common in nature. However, the mechanisms underlying speciation are not understood. READ MORE

  7. 5. Family matters : Essays in Applied Microeconomics

    Author : Sara Mikkelsen; Nationalekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Portfolio choice; Wealth; Children; Fertility; Consumption; Mobility; Paternity leave; Gender; Education; STEM; Sex composition; Twins; Income;

    Abstract : This thesis consists of four self-contained papers in applied microeconomics with family as a common theme. The first paper documents how the financial portfolios of parents change in response to the birth of a child. READ MORE
