  1. 1. Diversification of predators in multi-trophic communities: A trait-based theoretical approach

    University essay from Lunds universitet/Examensarbeten i bioinformatik

    Author : Julio Antonio Ayala Lopez; [2022]
    Keywords : Biology and Life Sciences;

    Abstract : One of the main challenges in ecology and evolutionary biology is to understand how biodiversity emerges and is maintained, given the complexity of ecological and evolutionary processes combined. Understanding how multi-trophic interactions occur from a theoretical perspective is highly relevant for our understanding of diversification in complex ecosystems. READ MORE

  3. 2. An Economic Proposition? Educational Assortative Mating and Earnings Inequality in Sweden, 2000-2010

    University essay from Stockholms universitet/Sociologiska institutionen

    Author : Simon Helperin; [2020]
    Keywords : Assortative mating; homogamy; earnings inequality; salary; economic inequality; decomposition; counterfactual analysis;

    Abstract : Educational assortative mating and earnings inequality has both increased in both Europe and the United States in the last decades. As a result, educational assortative mating, or educational homogamy, has been suggested as a potential explanation for the increase in earnings inequality. READ MORE

  4. 3. The Basis of Reproductive Isolation Between Ecologically Divergent Host Plant Races

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Emma Kärrnäs; [2018]
    Keywords : Biology and Life Sciences;

    Abstract : Insects and their host plants constitute a considerable proportion of the diversity on earth, and host shifts hence provide excellent study systems to study the process that drive diversification. In this study, I address what the mechanism to achieve assortative mating is in two host races using different host plants to increase our understanding of how reproductive isolation can arise in the face of ecological specialization.

  5. 4. Sperm morphology and reproductive isolation in Ficedula flycatchers

    University essay from Zooekologi; Institutionen för biologisk grundutbildning

    Author : Murielle Podevin; [2011]
    Keywords : evolution; speciation; sperm; flycatchers; gametic isolation; hybridization;

    Abstract : Speciation lies at the heart of evolution and the study of reproductive barriers allows a better understanding of the different steps leading to the complete isolation of two species. Pre-mating (behavior tactics, habitat or food divergence, phenotypic divergence and assortative mating) and post-mating, post-zygotic isolation barriers (selection against unfit hybrids) are well studied in numerous species, but little is known about what is happening between insemination and fertilization (post-mating, pre-zygotic isolation barriers).
