Abstract

Istraživanja fitoplanktonske zajednice provedena su u jezeru Crniševo koje pripada Baćinskim jezerima. Uzorci su prikupljani mjesečno od travnja do rujna 2010. godine na dubinama od 1, 5, 10, 15, 20 i 25 metara i analizirani su Utermöhl-ovom metodom. Glavni ciljevi istraživanja bili su 1) odrediti taksonomski sastav fitoplanktonske zajednice, njezinu brojnost i biomasu u krškom jezeru, 2) primijeniti funkcionalni i morfološki bazirani funkcionalni pristup, 3) odrediti koji opis zajednice je... More najprihvatljiviji u razumijevanju sukcesije fitoplanktonske zajednice. U jezeru Crniševo dominatna vrsta bila je Ceratium hirudinella, dok su Dinobryon divergens, Ankistrodesmus sp. i Oocystis sp. bile kodominantne vrste. Dominatna funkcionalna grupa bila je LO, a grupe E, J, B su se pojavljivale kao kodominantne. Dominantna morfološki bazirana funkcionalna grupa bila je V osim u srpnju kada je bila dominantna grupa IV a kodominatna VI. Biomasa fitoplanktona bila je u rasponu od 0,08 mg l-1 (svibanj, lipanj) do 2,86 mg l-1 (kolovoz) kada je dostignut maksimum (Peridiniopsis borgei). Zaključak je da morfološki bazirane funkcionalne grupe na uspješan način opisuju fitoplanktonsku zajednicu te zajedno s taksonomskim pristupom olakšavaju razumijevanje sukcesije fitoplanktona. Morfološki bazirane funkcionalne grupe imaju prednost u odnosu na taksonomsku i funkcionalnu klasifikaciju zbog jednostavnog i objektivnog pristupa. Less

Abstract (english)

The phytoplankton assemblages were investigated in Lake Crniševo that belongs to group of Baćinska Lakes. Samples were collected monthly from April to September 2010 at the 1, 5, 10, 15, 20 and 25 meters depth and analysed with Utermöhl method. The main aims of the investigation were to 1) determine taxonomic composition of phytoplankton assemblage, its abundance and biomass in a karstic lake and furthermore; 2) apply functional and morphologicaly based approach; 3) determine which... More description of the community is the most appropriate in understanding phytoplankton sucession. In the Lake Crniševo dominant species was Ceratium hirudinella while Dinobryon divergens, Ankistrodesmus sp. and Oocystis sp. were codominant. Dominant functional group was LO with groups E, J and B as codominant functional groups. Dominant morphologicaly based group was IV and codominant VI. Phytoplankton biomass varied from 0, 08 mg l-1 (May, June) to 2, 86 mg l-1 (August) when maximum biomass has been reached (Peridiniopsis borgei). In conclusion, morphologicaly based functional groups describe phytoplankton assemblage sucessfully and together with functional approach make understanding of fitoplankton sucession easier. Morphologicaly based groups have an advantage in relation to taxonomic and functional clasification due to easy and objective approach. Less
