20.500.12556/DiRROS-18940 Contribution to the knowledge of Gongolaria barbata (Sargassaceae, Fucales) from the Mediterranean insights into infraspecific diversity Gongolaria barbata (Sargassaceae, Fucales) is a widespread species for which several infraspecific taxa have been described, indicating its polymorphism. This study contributes to the understanding of the molecular, nomenclatural, morphological and ecological aspects of G. barbata in the Mediterranean and sheds light on the infraspecific diversity and its implications for the taxonomy of this species. Molecular analyses were performed using sequencing of the mitochondrial cox1 gene on both haptophytic and pleustophytic forms from different sites in the Adriatic and Tyrrhenian Seas. Vegetative and reproductive morphology was studied on thalli samples from the Adriatic. Our results showed that there are different morphotypes within G. barbata populations related to specific environmental conditions, suggesting infraspecific variation. In contrast, molecular analyses showed no differences between samples, regardless of whether individuals are growing “attached” to a substrate or “unattached”. We also discussed the taxonomic status and nomenclatural issues related to certain infraspecific taxa previously proposed for G. barbata. In particular, the confusion surrounding Cystoseira aurantia is clarified. ecotypes taxonomy Northern Adriatic Cystoseira s.l. ekotipi taksonomija severni Jadran Cystoseira s.l. true false true Angleški jezik Slovenski jezik Neznano 2024-05-16 13:35:47 2024-05-16 13:35:47 2024-05-23 11:42:48 0000-00-00 00:00:00 2024 0 0 str. 191–205 no. 3 Vol. 635 2024 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 2024-01-24 582.24 1179-3155 10.11646/PHYTOTAXA.635.3.1 183199491 RAZ_Falace_Annalisa_2024.pdf RAZ_Falace_Annalisa_2024.pdf 1 A86D65521229CB73B6FF4CB12EB574C7 979d9fbb125cd5041f99a9ea27d508c6aa9ba9e40f40aa9b8f922b1938dcbc6b b5d26df7-137e-11ef-9c9e-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25962 Nacionalni inštitut za biologijo 0 0 0
