  1. 1. Color and wing size: identifying targets of sexual selection in Drosophila melanogaster

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Ellen Pääjärvi Våg; [2024]
    Keywords : Sexual selection; wing interference patterns; Drosophila melanogaster; visual signaling; sexuell selektion; vingmönster; bananfluga; visuell signalering;

    Abstract : This study explores the relationship between wing size, coloration, and reproductivesuccess in Drosophila melanogaster, fruit flies. Sexual selection, a key aspect ofevolutionary biology, often involves visual signaling as a means of displaying geneticinformation. READ MORE

  3. 2. Differences in velocity between the sexes and stages of courtship in a dance fly

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Filip Myllyaho; [2022-02-17]
    Keywords : Dansfluga; Hilara maura; höghastighetskamera; partner-val; Dance fly; Hilara maura; high-speed camera; mate choice;

    Abstract : Dance flies (Diptera: Empididae: Empidinae) are famous for their elaborate mating behaviour, which can be broken down to three distinct stages in adults: hunting, swarming, and mating. In many species, males hunt for prey that they present as nuptial gifts to recipient females in swarms, after which the pair will copulate in the air or after landing on nearby vegetation. READ MORE

  4. 3. 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

  5. 4. Polyandry and genetic diversity in populations of Pholidoptera griseoaptera along an environmental gradient

    University essay from SLU/Dept. of Ecology

    Author : Matilda Jutzeler; [2019]
    Keywords : polyandry; genetic diversity; multiple mating; microsatellites; nuptial gift; phenotype;

    Abstract : Polyandry is a common mating pattern in different insect species and it leads to increased genetic diversity in the offspring and prevents inbreeding in populations. According to the theory of mate choice, mates should choose a partner that will increase heterozygosity in their offspring. READ MORE

  6. 5. Parasite burden and reproductive success

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Monica Höjerslev; [2018]
    Keywords : parasiter; parasitbelastning; reproduktion; reproduktionsframgång; sexuella signaler; ornament;

    Abstract : Reproduction is fundamental for passing on genes and secure species survival. One crucial point of this is mate choice, mating with an unbeneficial partner, they risk less advantageous offspring than if a better mate had been chosen. To be able to make these choices, sexual signals, or ornaments, are very useful tools. READ MORE
