  4. 2. Fungal taxonomy and systematics in the digital era, with an outlook on the cantharelloid clade (Basidiomycota)

    Author : R. Henrik Nilsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cantharelloid clade; ectomycorrhiza; Agaricomycetes; phyloinformatics; barcoding;

    Abstract : Fungi form a large and ubiquitous group of organisms where species identification and delimitation on morphological grounds often fall short. DNA sequences have proved an invaluable information source for these pursuits and are now routinely used in most mycological laboratories. READ MORE

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

    Author : Svante Martinsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oligochaeta; species delimitation; Clitellata; Annelida; DNA-barcoding; cryptic species; Enchytraeidae; Lumbricidae; Naididae;

    Abstract : 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.

  6. 4. Patterns and Processes of Evolution in Sundaland

    Author : Robert-Jan den Tex; Jennifer A. Leonard; Lawrence R. Heaney; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Systematics and phylogenetics; Systematik och fylogeni; Genetics; Genetik; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Biodiversity in the tropics is disproportionately high compared to other habitats, and also under disproportionate threat from human impact. It is necessary to understand how this diversity evolved and how it is partitioned across space in order to preserve it. READ MORE

  7. 5. Desert Plants and Deserted Islands : Systematics and Ethnobotany in Caryophyllaceae

    Author : Anneleen Kool; Mats Thulin; Gudrun Kadereit; Uppsala universitet; []

    Abstract : Background. Caryophyllaceae is a large and cosmopolitic flowering plant family, however the systematics of many of its basal groups has been unclear, due to a lack of unambiguous morphology. Some members of Caryophyllaceae are used medicinally, e.g. READ MORE
