  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. The relative effect of gained extra-pair paternity versus ensured within-pair paternity on male fitness in collared flycatchers, Ficedula albicollis

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Lan Ma; [2022]
    Keywords : ;

    Abstract : Variation in a male ability to gain extra-pair paternity and maintain within-pair paternity are important sources of variation in male fitness in socially monogamous species and thus become the resource of sexual selection on male secondary sexual traits. While the maximum possible number of offspring sired within the social pair-bond is limited by the female’s clutch size, the possible number of sired extra-pair young could in theory by much higher.

  5. 4. 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

  6. 5. Sexually segregated habitat selection in Daubenton’s bat Myotis daubentonii

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Esnart Emma Bwalya Chibwe; [2021]
    Keywords : sexual segregation; Daubenton’s bat; Myotis daubentonii; landscape analysis; habitat selection; foraging;

    Abstract : Sexual segregation is a phenomenon present in many vertebrate taxa, including the bat order Chiroptera. Sexual segregation is a social and/or habitat separation based on sex and is driven by varying causes such as sexual dimorphism, resource and physiological limitations, predator avoidance and many other factors.
