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

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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Fekunditet hos honor av Drosophila melanogaster med en potentiell sexuellt antagonistisk gen : En fördjupande studie inom experimentell validering av en potentiell sexuellt antagonistisk gen hos Drosophila melanogaster

    Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Sara Lindh; [2022]
    Nyckelord :sexual antagonism; sexual conflicts; fruitflies; drosophila melanogaster; drosophila; GWAS; antagonistic sexual selection; fecundity; intralocus sexual conflict; reproductive fitness; sexuell konflikt; sexuella konflikter; drosophila melanogaster; drosophila; bananflugor; sexuell antagonism; fekunditet;

    Sammanfattning : Sexual conflicts arise when there is a difference in how females and males of a species or population achieve their maximum reproductive fitness. In intralocus sexual conflicts, alleles at a given locus are exposed to conflicting, or antagonistic, selection pressures. LÄS MER

  4. 3. Analyzing the use of Humidity Cue in Navigation of Drosophila melanogaster

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Kalle Andersson; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Humidity is one of the main abiotic factor of ecosystems and affects animals behaviour, fitness and distribution. Due to their small size and inability to thermoregulate using metabolism, insects, such as the fruit fly Drosophila Melanogaster, are especially reliant on humidity. LÄS MER

  5. 4. 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. 5. 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
