  1. 1. Integrative Approaches Illuminate Evolutionary Divergence in the Bar-tailed Lark Complex ( Ammomanes cinctura)

    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. Fine-scale recombination landscape in the wood white butterfly Leptidea sinapis

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Aleix Palahí i Torres; [2021]
    Nyckelord :recombination; butterfly; Leptidea; population;

    Sammanfattning : Recombination is a genetic process of extreme importance in evolutionary biology. It creates novel haplotypes and breaks down existing ones, and can affect the levels of genetic diversity and the efficacy of selection. It also plays an important role in the evolution of sex chromosomes and the divergence process leading to speciation. LÄS MER

  4. 3. Developing new methods for estimating population divergence times from sequence data

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Karl Svärd; [2021]
    Nyckelord :genetics; evolution; bioinformatics; migration; demography; beta distributions; population genetics; numerical methods; simulations; genetik; evolution; bioinformatik; migration; demografi; betafördelning; populationsgenetik; numeriska metoder; simulationer;

    Sammanfattning : Methods for estimating past demographic events of populations are powerful tools in order to get insights of otherwise hidden pasts. The genetic data of people is a valuable resource for these purposes as patterns of variation can inform of the past evolutionary forces and historical events that generated them. LÄS MER

  5. 4. Effects of whitefish speciation on piscivorous birds : A dietary study of piscivorous birds in central and northern Sweden

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

    Författare :Erik Söderlund; [2021]
    Nyckelord :Coregonus lavaretus; piscivorous; birds; diet; speciation;

    Sammanfattning : The ecological communities we observe today are a product of the bidirectional interactions between ecological and evolutionary processes. Although the effects of ecological processes on population divergence and speciation have been studied extensively, far less is known about the effects of divergence and speciation on ecological dynamics.

  7. 5. Exploration of an all-atom thermodynamic model to predict site-specific evolutionary rates in proteins

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Fábio Dias Correia de Oliveira; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Understanding the patterns of evolutionary sequence divergence is fundamental for comparative analyses like phylogenetics or genomics. The rate at which the different sites of protein sequences evolve is multifactorial and the causes of variation among them are highly convoluted. LÄS MER
