  4. 3. Large-scale releases of native species : the mallard as a predictive model system

    Författare :Pär Söderquist; Högskolan Kristianstad; Sveriges lantbruksuniversitet; []

    Sammanfattning : Human alteration of natural systems, and its consequences are of great concern and the impact on global ecosystems is one of the biggest threats that biodiversity stands before. Translocations of invasive species, as well as intraspecific contingents with non-native genotypes, whether they are deliberate or unintentional, are one such alteration and its consequences are continuously being assessed.

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

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Svante Martinsson; Göteborgs universitet; []
    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
