Biodiversity of Collembola and their functional role in the ecosystem

摘要: More than 6500 species of Collembola are known from throughout the world and these only a small part still undescribed species. There many checklists catalogues for smaller territories entire continents. Biogeographical analyses have been made some genera territories. The most serious problems global biogeographical analysis is lack enough records immense all Local biodiversity can be very high, reaching over 100 in mountain ranges. Sampling methods do not impede documenting on scale. well differentiated ecomorphological life-forms feeding guilds which enable functional role that play ecosystems to recognised degree. an important plant litter decomposition processes forming soil microstructure. They hosts parasitic Protozoa, Nematoda, Trematoda pathogenic bacteria turn attacked by different predators. utilise as food Rotatoria, Enchytraeidae, invertebrate carrion, bacteria, fungi, algae, litter, live tissues, pathogens. Soil acidification, nitrogen supply, climate change intensive farming greatly impacted collembolan diversity.
