20.500.12556/DiRROS-21720 The impact of sewage discharge on nutrients and community production in a lagoon environment (Lagoon of Strunjan, Gulf of Trieste, northern Adriatic Sea) - a revisited experiment Vpliv vnosa komunalnih odplak na hranila in produkcijo v lagunarnem okolju (Strunjanska laguna) - ponovni ogled poskusa A specially constructed enclosure in the lagoon environment (Lagoon of Strunjan, Gulf of Trieste, northern Adriatic Sea) received sewage daily while another was kept clean and used as a reference. Nutrients and community production changes were monitored approximately bimonthly over a year. Nutrients introduced by the sewage discharges and diluted by tides were immobilized by enhanced community production, in particular benthic macroalgae. The dead organic matter afterwards settled and decomposed producing anoxic conditions and high levels of dissolved and suspended organic nutrients in the water and total nitrogen in the sediments. The daily mean gross community production showed no quantitative differences between the two enclosures during the study. Differences arose in the temporal succession of the studied events. An intensive nutrient recycling emerged from this study. V posebej zgrajeni bazen v Strunjanski laguni smo dnevno uvajali komunalne odplake mesta Piran, medtem ko je drugi služil za primerjavo. V odbobju enega leta smo s približno dvomesečno frekvenco spremljali gibanja koncentracij hranil in produkcije. Vnešena hranila, redčena s plimovanjem, so povečala produkcijo predvsem bentoških makroalg. Odmrla organska snov se je nato posedla in razgrajevala ter povzročila nastanek anoksije in visokih koncentracij raztopljene in suspendirane organske snovi in celotnega dušika v sedimentu. Srednja dnevna bruto produkcija v celoletnem obdobju ni pokazala velikh razlik med bazenoma, medtem ko so bile lete opazne v časovnem poteku študiranih procesov. Iz poskusa je razvidno intenzivno kroženje vnešenih hranil. carbon lagoons nutrients northern Adriatic oxygen production (biology) hranila kisik lagune ogljik produkcija (biologija) severni Jadran true false true Angleški jezik Slovenski jezik Neznano 2025-03-19 08:28:50 2025-03-19 08:28:50 2025-03-20 03:40:24 0000-00-00 00:00:00 2021 0 0 Nasl. z nasl. zaslona; Besedilo v angl.; Opis vira z dne 21. 12. 2022; str. 42-56 št. 2 Letn. 64 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2021-12-01 574 1854-3073 93844995 ABS_2_2021_5Faganeli.pdf ABS_2_2021_5Faganeli.pdf 1 E8CAF4A619D9FD5DAD3DCB5597AC6F2E aa8073b3e21101c288d557afe4ccd02bbe21da39105fdce1bd60e7c4e574ab2c ce37f3a3-0493-11f0-963a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=31172 http://www.dlib.si/details/URN:NBN:SI:DOC-WLNV0UGQ 0 ee91acc9-0493-11f0-963a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=31173 https://www.dlib.si/stream/URN:NBN:SI:DOC-WLNV0UGQ/cfd4aa67-2bb7-40a0-af72-ae6d367abfc5/PDF 0 f3c9e9d9-0493-11f0-963a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=31174 Nacionalni inštitut za biologijo 0 0 0
