  1. 1. Riveted : Levinas' Early Stuff

    Master-uppsats, Uppsala universitet/Avdelningen för teoretisk filosofi

    Författare :Aron Ericson; [2022]
    Nyckelord :Levinas; transcendence; excendence; phenomenology; ontology; Heidegger;

    Sammanfattning : This study is an examination of the early philosophical writings by Emmanuel Levinas, and shows how transcendence became his guiding question. The study has three parts. Part One lays out Levinas' early enthusiasm with regard to Heidegger's phenomenology. Part Two consists of close readings of three essays by Levinas from 1933 to 1935. LÄS MER

  2. 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

  3. 3. 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

  4. 4. Friends with benefits? - Does gut microbiota of Spodoptera littoralis affect insecticide resistance and are there any costs of insecticide resistance development?

    Master-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Sarah Heithausen; [2021]
    Nyckelord :insecticide resistance development; gut microbiota; gut symbiont-mediated resistance; trade-off effects; fitness costs; symbiosis; survival; life-history traits; fecundity;

    Sammanfattning : The insect gut microbiota has many important functions for insects such as detoxification of host plant toxins. Recently there has been a growing interest on the effect of insect gut microbiota on insecticide resistance development. Insecticide resistance is a growing concern for food security and sustainable agriculture. LÄS MER

  5. 5. Spatiotemporal variation in the relative fitness of a northern and a southern ecotype of Arabidopsis thaliana

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Jonathan Gyllingberg; [2021]
    Nyckelord :Arabidopsis thaliana; fitness; evolution; ecotype; genotype; flowering phenology; fecundity; local adaptation;

    Sammanfattning : Terrestrial plants exist in almost every habitat on the earth, ranging from warm and moist tropical rainforests, hot and dry deserts, and to cold and barren tundras. Furthermore, a single species may encounter different climatic conditionshabitats within its range distribution which climatic conditions differs from one to another. LÄS MER
