  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. Trends in mountain birch seed abundance and its relation to temperature and moth abundance: a ten-year study from Swedish Lapland

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Frida Gustafsson; [2023-02-09]
    Nyckelord :Betula pubescens; climate change; seed production; Epirrita autumnata; Operophtera brumata; subarctic ecology; folivory; larval abundance;

    Sammanfattning : Boreal forest is the world’s largest terrestrial biome. Being one of the most ubiquitous and coldtolerant tree species in Sweden, the mountain birch forms a unique deciduous treeline and marks the forest-tundra ecotone. LÄS MER

  4. 3. “THE ENDLESS BATTLE” France's Path to Legalizing Abortion : The Spiral Approach

    Master-uppsats, Enskilda Högskolan Stockholm/Avdelningen för mänskliga rättigheter och demokrati

    Författare :Tannaz Horri Farahani; [2023]
    Nyckelord :France; Abortion law; Feminist movements; Social change; Human rights; Spiral model.;

    Sammanfattning : This abstract provides a concise summary of the thesis, which examines the evolution of abortion laws in France and the intersection of women's rights, feminism, and healthcare. It emphasizes the shift from a complete ban on abortion to legalization and analyses the factors contributing to this social change, focusing on the role of feminist movements and women's rights activists.

  5. 4. Population dynamics of the spruce bark beetle Ips typographus in forest conservation areas and the interaction with biodiversity and natural enemies

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Evelina Andersson; [2023]
    Nyckelord :spruce bark beetle; population dynamics; conservation areas; biodiversity; natural enemies; species richness; managed forests; woodland key-habitats; nature reserves;

    Sammanfattning : Biodiversity is rapidly decreasing and in need of more conservation efforts. However, the tree-killing European spruce bark beetle, Ips typographus (L.), has made forest conservation controversial by affecting conservation areas and possibly adjoining managed forests, yet is still a keystone species leaving decaying wood promoting biodiversity.

  7. 5. FOREST LANDSCAPE STRUCTURE OF CAPERCAILLIE (TETRAO UROGALLUS) LEK SITES IN NORTHERN SWEDEN : Analysis of lek site characteristics

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Agnes Blomgren; [2023]
    Nyckelord :capercaillie Tetrao urogallus ; habitat selection; forest landscape structure; lek site;

    Sammanfattning : The purpose of this study is to analyze which variables influence the capercaillie’s (Tetrao urogallus) selection of lek sites in northern Sweden by using remote sensing data. The lek site is a crucial area for the species’ reproductive success. LÄS MER
