  2. 21. Environmental sequencing to infer patterns of eukaryotic evolution : Combining long-read and short-read metabarcoding

    Author : Mahwash Jamy; Fabien Burki; Micah Dunthorn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protists; eukaryotes; environmental sequencing; ribosomal DNA; PacBio; long-read metabarcoding; phylogenetics; salt barrier; habitat evolution; eukaryotes evolution; evolutionary rate; Apicomplexa; pathogen; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : Our view of eukaryotes is biased towards plants, animals, and fungi. But the vast majority of eukaryotic diversity is microbial in nature. These microbial eukaryotes are key players in all ecosystems on earth and are collectively known as protists. READ MORE

  4. 22. Evolution of Vertebrate Vision by Means of Whole Genome Duplications : Zebrafish as a Model for Gene Specialisation

    Author : David Lagman; Dan Larhammar; Xesús M Abalo; Finn Hallböök; Stephan Neuhauss; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phylogenetics; evolution; vision; visual opsin; transducin; PDE6; genome duplications; subfunctionalisation; Medicinsk vetenskap; Medical Science;

    Abstract : The signalling cascade of rods and cones use different but related protein components. Rods and cones, emerged in the common ancestor of vertebrates around 500 million years ago around when two whole genome duplications took place, named 1R and 2R. READ MORE

  5. 23. Probabilistic Reconciliation Analysis for Genes and Pseudogenes

    Author : Owais Mahmudi; Jens Lagergren; Cedric Chauve; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phylogenetics; Evolution; Reconciliation Analysis; Bayesian Inference; Datalogi; Computer Science;

    Abstract : Phylogeneticists have studied the evolution of life from single celled organisms to the astonishing biodiversity around us for a long time now. The relationship between species is often expressed as a binary tree - the tree of life. READ MORE

  6. 24. Exploration of microbial diversity and evolution through cultivation independent phylogenomics

    Author : Joran Martijn; Thijs J.G. Ettema; Andrew Roger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cultivation independent genomics; metagenomics; single-cell genomics; metagenomic binning; phylogenetics; phylogenomics; phylogenetic artefacts; comparative genomics; gene tree-species tree reconciliation; rRNA amplicon sequencing; Tara Oceans; origin of mitochondria; Alphaproteobacteria; Rickettsiales; Haloarchaea; endosymbiosis; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Our understanding of microbial evolution is largely dependent on available genomic data of diverse organisms. Yet, genome-sequencing efforts have mostly ignored the diverse uncultivable majority in favor of cultivable and sociologically relevant organisms. READ MORE

  7. 25. Through the magnifying glass - The big small world of marine meiofauna : Morphology, species and evolution in Nemertodermatida

    Author : Inga Meyer-Wachsmuth; Ulf Jondelius; Mark E Sidall; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nemertodermatida; Acoelomorpha; morphology; CLSM; Phalloidin; musculature; DNA; cryptic species; species delimitation; dispersal; taxonomy; phylogenetics; IHC; nervous system; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : Nemertodermatida is a group of microscopic marine worm-like animals that live as part of the marine meiofauna in sandy or muddy sediments; one species lives commensally in a holothurian. These benthic worms were thought to disperse passively with ocean currents, resulting in little speciation and thus wide or even cosmopolitan distributions. READ MORE
