    Abstract : Echiochilon, Ogastemma and Sericostoma are revised resulting in the recognition of 15 species of Echiochilon and one Ogastemma species. Several species are placed in synonymy and three new species are described, E. baricum, E. callianthum and E. READ MORE

  4. 22. Phylogeny, taxonomy and species delimitation of water mites and velvet mites

    Abstract : 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. READ MORE

  5. 23. Tubificids with trifid chaetae: morphology and phylogeny of Heterodrilus (Clitellata, Annelida)

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heterodrilus; phylogeny; morphology; Tubificidae; Systematics and phylogenetics; Systematik och fylogeni; Systematic Zoology; systematisk zoologi;

    Abstract : Heterodrilus is a marine group of small (3-25 mm) clitellates that occur interstitially in sandy sediments from the intertidal zone down to about 150 m depths. The taxon includes 42 valid species and has been recorded from localities in the Mediterranean Sea, the North-west Atlantic Ocean (including the Caribbean), the Galapagos Islands, and the Indo-Pacific Region.

    Keywords : Biology; taxonomy; phylogeny; molecular phylogenies; cryptic species; micro-invertebrate; Biologi; Catenulida; Platyhelminthes;

    Abstract : This thesis focuses on phylogenetic and taxonomic studies of Catenulida (Platyhelminthes). Catenulida is a group of microscopic free-living worms mainly found in freshwater habitats. The Swedish catenulid fauna was previously virtually unknown. READ MORE

  7. 25. Molecular phylogeny of tyrant flycatchers, cotingas, manakins and their allies (Aves: Tyrannida)

    Keywords : Suboscines; Tyrannida; Tyrannidae; Cotingidae; Pipridae; South America; phylogeny; evolution; adaptive radiation; NATURAL SCIENCES; NATURVETENSKAP; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Abstract : Tyrannida is a monophyletic clade that together with Furnariida constitutes the New World suboscines. The ca 560 species in Tyrannida are traditionally divided between three families: Tyrannidae (tyrant flycatchers), Cotingidae (cotingas) and Pipridae (manakins). READ MORE
