  1. 1. Systematics of Marionina (Annelida: Clitellata: Enchytraeidae)

    Författare :Lisa Matamoros; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Marionina; Michaelsena; Enchytronia; Enchytraeidae; cryptic species; molecular phylogeny; taxonomy; systematics; genetic diversity;

    Sammanfattning : This thesis is about species of segmented worms that previously were placed in the genus Marionina Michaelsen, 1890, within the family Enchytraeidae, class Clitellata and phylum Annelida. These species are closely related to earthworms, but are much smaller and many of them are found between the sand grains in marine beaches. LÄS MER

  2. 2. Systematics of Grania (Clitellata: Enchytraeidae), an interstitial annelid taxon

    Författare :Pierre De Wit; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Clitellata; Oligochaeta; Enchytraeidae; Grania; interstitial habitat; systematics; phylogeny; DNA barcoding; cryptic species;

    Sammanfattning : In between the grains of sand on the ocean floor, there exists a world which few people are aware of. Representatives of almost all animal phyla can be found here. LÄS MER

  3. 3. Exploring the species boundaries in terrestrial clitellates (Annelida: Clitellata)

    Författare :Svante Martinsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Oligochaeta; species delimitation; Clitellata; Annelida; DNA-barcoding; cryptic species; Enchytraeidae; Lumbricidae; Naididae;

    Sammanfattning : The biological diversity in the soil is much higher than most people can imagine, and a very important group of animals living there are earthworms and other clitellate worms. It has been found that several clitellate morphospecies are in fact complexes of so called cryptic species, and the number of species in this group may be much higher than previously believed.

  5. 5. On enchytraeids and naidids: Life history traits and responses to environmental stress

    Författare :Anna-Karin Augustsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ecology; oligochaeta; terrestrial naididae; toxicity testing; asexual reproduction; sexual reproduction; drought; environmental stress; metal pollution; Ekologi; Animal ecology; Djurekologi;

    Sammanfattning : My thesis shows that enchytraeids and naidids are sensitive to various forms of environmental stress, which in combination with the wide distribution of both families make them highly suitable for use in risk assessment and soil monitoring. Enchytraeids were subject to chemical stress under both laboratory and field conditions. LÄS MER
