20.500.12556/DiRROS-19303 Biodiversity patterns of cyanobacterial oligotypes in lakes and rivers results of a large-scale metabarcoding survey in the Alpine region In this work, we characterised the cyanobacterial communities in the plankton and littoral biofilm of 38 lakes and in the biofilm of 21 rivers in the Alps and surrounding subalpine regions by 16S rRNA gene metabarcoding. We found little overlap in the distribution of amplicon sequence variants (ASVs) between the three habitats and between water bodies. The differences were caused by environmental filtering acting on the selection of the most abundant ASVs and a high contribution of rare oligotypes. The differentiation of community and genotype composition from specific water bodies was explained to a significant extent by environmental variables and morphometry. The taxonomic consistency of ASVs classified under the same genus name was assessed by phylogenetic analyses performed on three representative dominant genera, namely Cyanobium, Tychonema and Planktothrix. The analyses revealed eco-evolutionary adaptations in lakes and rivers, including some evidence for a polyphyletic nature. Monitoring individual genotypes in relation to environmental conditions will be useful to define the ecological amplitude of these taxa. However, the persistence or ephemeral nature of some of the rarest and most unusual ASVs has remained unknown. plankton littoral bioflm European Alps phylogenetic analysis toxigenic cyanobacteria površinske vode plankton ekologija filogenija cianobakterije biodiverziteta true false true Angleški jezik Slovenski jezik Neznano 2024-07-15 09:40:04 2024-07-15 09:40:05 2024-07-16 03:45:12 0000-00-00 00:00:00 2023 0 0 Soavtorji: Serena Bernabei, Adriano Boscaini, Camilla Capelli, Leonardo Cerasino, Isabelle Domaizon, Tina Elersek, Claudia Greco, Aleksandra Krivograd Klemenčič, Paolo Tomassetti & Rainer Kurmayer; Članek v PDF formatu obsega 28 str.; Online first: 12 December 2023; 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2023-12-12 574 0018-8158 10.1007/s10750-023-05423-z 178197507 https://doi.org/10.1007/s10750-023-05423-z 1 76717419-427d-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=26620 RAZ_Salmaso_Nico_2023.pdf RAZ_Salmaso_Nico_2023.pdf 1 B1A217219B5D74B3A8FE0AEBD155D96F 25c795e03356f2e90ee59334e451e825f661a9a8354560e9f7094d8448f782b7 f3b062f5-427d-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=26621 Nacionalni inštitut za biologijo 0 0 0
