20.500.12556/DiRROS-20167 Unusual expansion of Laurencia obtusa (Hudson) J.V. Lamouroux in the Zambratija Bay (northern Adriatic Sea) Espansione insolita di Laurencia obtusa (Hudson) J. V. Lamouroux nella Baia di Zambrattia (Adriatico settentrionale) The paper reports an unusual expansion of the red alga Laurencia obtusa in shallow waters of the Zambratija Bay (northern Adriatic Sea). The large population of L. obtusa was never observed during underwater surveys conducted in recent years. In this area, benthic communities dominated by brown algae from the genus Cystoseira were present. The authors therefore assume that some environmental factors have probably changed and have favoured the extension of this red alga. The hypothesis for this phenomenon takes into account the possibility that the establishment of the invasive green alga Caulerpa cylindracea in the Zambratija bay has had a negative impact on native macroalgal assemblages. L’articolo riporta un’insolita espansione dell’alga rossa Laurencia obtusa in acque poco profonde della baia di Zambrattia (Adriatico settentrionale). Ampi popolamenti di L. obtusa non sono mai stati osservati durante le indagini subacquee effettuate negli ultimi anni. In quest’area erano presenti comunità bentoniche dominate da alghe brune del genere Cystoseira. Gli autori pertanto suppongono che alcuni fattori ambientali siano cambiati e abbiano favorito l’estensione di quest’alga rossa. L’ipotesi per questo fenomeno prende in considerazione la possibilità che l’insediamento dell’alga verde invasiva Caulerpa cylindracea nella baia di Zambrattia abbia avuto un impatto negativo sulle associazioni macroalgali autoctone. algae shallow waters monospecific populations Zambratija Bay Adriatic Sea alge pojavljanje rdeče alge obalno morje Laurencia obtusa Algae true false true Angleški jezik Italijanski jezik Neznano 2024-08-07 07:42:46 2024-08-07 07:42:47 2024-08-08 04:07:50 0000-00-00 00:00:00 2017 0 0 str. 1-6 št. 1 Letn. 27 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2017-06-15 581(497.4) 1408-533X 10.19233/ASHN.2017.01 4379215 RAZ_Orlando-Bonaca_Martina_2017.pdf RAZ_Orlando-Bonaca_Martina_2017.pdf 1 53FA7BF4F21D6C066F14D3FD355CA68D 05a787454fb122975dbcc0a4655a29f1db35c900347c7706eab78082cf61d6ea 624a08a6-546f-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28186 https://zdjp.si/it/annales-series-historia-naturalis-27-2017-1/ 0 6cf8c99a-546f-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28187 http://www.dlib.si/details/URN:NBN:SI:doc-PZUJJUJM 0 77676370-546f-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28188 Nacionalni inštitut za biologijo 0 0 0
