  1. 11. The role of copulatory wound infliction on fitness in Drosophila melanogaster

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Dennis Leandersson; [2021]
    Nyckelord :Copulatory wounding; Fecundity; Drosophila; Fitness; Cryptic female choice; Adaptive harm hypothesis; Pleiotropic harm hypothesis;

    Sammanfattning : One of the more fascinating Darwinian puzzles in sexual selection is that of copulatory wounding. For those taxa displaying this behavior, and that does not engage in traumatic insemination, the function of wound infliction during copulation remains unknown. LÄS MER

  3. 12. Statistical Analysis and Modeling of the Behavioral Response to Humidity and Olfactory Cues by the Vinegar Fly Drosophila melanogaster

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Jonathan Lind; [2021]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Animals are impacted by the humidity of their surrounding environment, it affects their ability of thermoregulation, water retention and their overall well-being. For small insects the effects of the surrounding humidity is even more important as they have a limited water storage which depletes faster in a drier environment. LÄS MER

  4. 13. An RNA comparison study between the Amazonian, Centro-American and Orinocan semispecies of Drosophila paulistorum

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Erik Hedman; [2020]
    Nyckelord :Drosophila paulistorum; D. paulistorum; RNA-seq; RNA-seq comparison study; Differential expression analysis; Amazonian semispecie; Centro-American semispecie; Orinocan semispecie;

    Sammanfattning : Differential expression analysis can be a powerful method to investigate expressed differences between closely related species. Our ambition is to highlight differentially expressed nuclear genes to explain the hybrid incompatibilities among the Amazonian, Centro-American and Orinocan semispecies of Drosophila paulistorum.

  5. 14. Visual neurons with different shapes: investigation of the relationship between morphology and function

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Love Federley Ottosson; [2020]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : In this project, morphological differences between motion detector neurons in Drosophila melanogaster were compared and used to speculate regarding their function. This was achieved by comparing properties such as diameter, height, width, bifurcation, asymmetry and terminal degree. LÄS MER

  7. 15. Method for coupling modulatedscattered light from free flyinginsects to harmonics and theirrelative phases

    Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk statistik

    Författare :Martin Patricks; Ludvig Anderberg; [2020]
    Nyckelord :frequency estimation; phase estimation; matched phase reassignment; entomologic lidar; modulation spectroscopy; scattered light; Technology and Engineering;

    Sammanfattning : Using laser it is possible to measure the backscattered light from insects. The resulting signal can then be analysed in order to potentially determine the species of the insect. LÄS MER
