  1. 1. Integrative taxonomy of birds : Studies into the nature, origin and delimitation of species

    Författare :George Sangster; Per G. P. Ericson; Martin Päckert; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aves; biogeography; integrative taxonomy; pluralism; ring species; speciation; species criteria; species limits; taxon chain; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : Species are the basic currency in biodiversity studies but what constitutes a species has long been controversial. A major breakthough was the insight that most systematists agree that species are segments of population lineages, and that multiple lines of evidence should be employed and integrated, a procedure called integrative taxonomy.

  3. 2. Phylogeny, taxonomy and species delimitation of water mites and velvet mites

    Författare :Jeanette Stålstedt; Johannes Bergsten; Fredrik Ronquist; Joanna Mąkol; Ashley Dowling; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acariformes; Parasitengona; Hydrachnidia; Trombidia; water mites; velvet mites; taxonomy; cryptic species; species delimitation; DNA; GMYC; experimental rearing; new synonyms; distribution; phylogeny; revised classification; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : This study is part of the Swedish Taxonomy Initiative (STI) - one of the most ambitious all taxa biodiversity inventories in the world. One of the pillars in STI is to support taxonomic research on the most neglected taxonomic groups with the aim to lift the level of knowledge of biodiversity in the country. LÄS MER

  4. 3. Species Limits, and Evolutionary History of Glassfrogs

    Författare :Santiago Castroviejo-Fisher; Carles Vilà; Jennifer A. Leonard; Miguel Vences; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amphibia; Anura; Biogeography; Centrolenidae; Diversification; Frogs; Molecular Phylogenetics; Neotropics; Pristimantis; Speciation; Species; Systematics; Taxonomy; Systematics and phylogenetics; Systematik och fylogeni; systematisk zoologi; Systematic Zoology;

    Sammanfattning : Recognizing the mechanisms of speciation and the limits of species is essential to understand the origin of biodiversity and how to conserve it. The general aims of my investigations during my doctoral studies were two-fold: to study evolutionary patterns and processes, and to provide specific and superspecific taxonomic classifications that try to reflect evolutionary history.

  5. 4. Fungal molecular ecology in boreal forests and challenges associated with unidentified environmental DNA sequences

    Författare :Kerri Kluting; Anna Rosling; Martin Ryberg; Sara Branco; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amplicon sequence variant ASV ; Archaeorhizomycetes; environmental DNA sequencing; high-throughput sequencing; integrative taxonomy; pine forest; podzol soil profile; Pucciniomycotina; Tomicus piniperda; voucherless specimens; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Many fungi are characteristically difficult to observe and collect, making the process of documenting the world’s fungal diversity challenging. The vast majority of fungal species are undescribed. LÄS MER

  7. 5. A multi-faceted approach to a "dark taxon" : The hyperdiverse and poorly known scuttle flies (Diptera: Phoridae)

    Författare :Emily Hartop; Fredrik Ronquist; Torbjørn Ekrem; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biodiversity; taxonomy; dark taxa; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : Most of the unknown animal biodiversity on earth is in groups of invertebrates that are hyperdiverse and abundant, yet poorly known (“dark taxa”). The study of these organisms requires a multi-faceted approach and methodologies designed to tackle large numbers of species and specimens. LÄS MER
