    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Zongzhuang Liu; [2023]
    Nyckelord :Alaudidae; Ammomanes cinctura; Integrative taxonomy; Genomics; Plumage; Evolutionary divergence;

    Sammanfattning : Ammomanes cinctura (Bar-tailed Lark) is a lark species with a wide distribution in the Palearctic. One of its subspecies, A. c. LÄS MER

  3. 2. Neanderthal genome sequencing : A genetic research study

    Kandidat-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historia

    Författare :Susanna Uhr; [2023]
    Nyckelord :aDNA; genome sequencing; method progression; Neanderthals; modern humans; genetic divergence; interbreeding; aDNA; genom sekvensering; metodutveckling; Neandertalare; moderna människor; genetisk splittring; korsning;

    Sammanfattning : The aim of this study is to provide information regarding the development of aDNA research. The essay also strives to distinguish eventual impact on previous and contemporary conceptions concerning Neanderthal and modern human genetic divergence and possible interbreeding between the two species.

  4. 3. Brain morphology and behavioural variation in relation to habitat and predation risk in minnows (Phoxinus phoxinus)

    Master-uppsats, Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Marina Gallego González; [2022]
    Nyckelord :brain size; Ecology; environmental complexity; European minnow; fish; geometric morphometrics; morphological divergence; phenotypic plasticity; schooling.;

    Sammanfattning : So far, research on inter- and intraspecific teleost brain plasticity across different freshwater environments has been widely conducted. However, insights of brain morphological variation on social and predator avoidance behaviours are lacking. LÄS MER

  5. 4. Sympatric Divergence in Whitefish Dwarfs : An investigation of phenotype-environment correlations in whitefish dwarfs

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

    Författare :Olivia Eriksson; [2021]
    Nyckelord :;

    Sammanfattning : Recent studies have found populations of European Whitefish (Coregonus lavaretus) to be under the process of divergence induced by a predator (pike, Esox lucius). This has caused whitefish to diverge into similar ecotypes but in separate lakes. LÄS MER

  7. 5. Modular design for a product family ofaesthetic medical laser devices

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Maxi Schubert; [2017]
    Nyckelord :product development; modularization; thermoforming; product family; brand DNA; produktutveckling; modularisering; varmformning; produktfamilj; varumärkes-DNA;

    Sammanfattning : This thesis covers a product development process carried out at the company “Asclepion Laser Technologies” for a product family of aesthetic medical laser devices. Due to different dimensions and dates of origin, an obvious divergence in the appearance of the present products within the product family had emerged in the company. LÄS MER
