1. ”Det kanske inte är så jätteattraktivt att se någon stå och hålla i en stor gädda liksom” : Heterosexuella kvinnors preferenser och resonerande av mäns profiler inom online-dejting
Kandidat-uppsats, Högskolan Väst/Institutionen för individ och samhälleSammanfattning : En stor del av dem som bildar par i Sverige har idag träffats på olika online-dejtingplattformar. Tidigare forskning har visat att kvinnor är mer selektiva i val av partner. Detta kan göra att män riskerar att bli bortvalda i dessa sammanhang, vilket kan medföra negativa konsekvenser för den enskilda individen och samhället i stort. LÄS MER
2. Assortativ parning hos sik (Coregonus lavaretus)
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : European whitefish (Coregonus lavaretus) forms reproductively isolated sub-populations with different body sizes in the lakes where northern pike (Esox lucius) exists. It has been hypothesized that the initial reproductive isolation between ecotypes arises through size-assortative mate choice or because small and large individuals arrive to the spawning grounds at different times.

3. Diversification of predators in multi-trophic communities: A trait-based theoretical approach
Master-uppsats, Lunds universitet/Examensarbeten i bioinformatikSammanfattning : 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. LÄS MER
4. An Economic Proposition? Educational Assortative Mating and Earnings Inequality in Sweden, 2000-2010
Master-uppsats, Stockholms universitet/Sociologiska institutionenSammanfattning : 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. LÄS MER
5. The Basis of Reproductive Isolation Between Ecologically Divergent Host Plant Races
Kandidat-uppsats, Lunds universitet/Examensarbeten i biologiSammanfattning : 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.
