After more than forty-five years a new finding of Cystoseira foeniculacea f. latiramosa in the coastal sea of SloveniaOrlando-Bonaca, Martina (Avtor) Trkov, Domen (Avtor) Canopy-forming macroalgae, especially Cystoseira sensu lato species, create so-called brown algal forests, which are among the most productive habitats in shallow coastal waters. In the Mediterranean Sea these species have been disappearing over the past two decades due to multiple anthropogenic pressures, and are gradually being replaced by smaller and persistent turf-forming algae. A decrease in the number of species and in the cover of canopy-forming taxa (especially Cystoseira s.l. spp.) has been detected over the last ten years also in Slovenian coastal waters. This paper reports a recent finding of Cystoseira foeniculacea f. latiramosa, which was missing from Slovenian marine waters for more than four decades.20202024-08-01 08:05:06Neznano19977UDK: 574:582.272:581ISSN pri članku: 1408-533XCOBISS_ID: 44355587sl
