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

    Detta är en avhandling från Göteborg

    Författare :Svante Martinsson; Göteborgs universitet.; Gothenburg University.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 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. LÄS MER
