Abstract
Kao posljedica globalnih klimatskih promjena sve se češće javljaju ekstremne poplave Dunava uzrokovane velikom količinom padalina ili otapanjem snijega. Ekosustavi poplavnih područja kao što je Kopački rit vrlo su osjetljivi na ekstremne hidrološke događaje. Cilj ovog rada je utvrditi utjecaje ekstremno velike i dugotrajne poplave Dunava u proljeće i ljeto 2013. godine na dinamiku fitoplanktona Sakadaškog jezera, plitkog jezera Kopačkog rita. Istraživanje je provedeno u jednomjesečnim intervalima od travnja do prosinca 2013. godine na središnjem dijelu Sakadaškog jezera. Za vrijeme velike lipanjske poplave utvrđena je niska biomasa fitoplanktona, a prevladavale su funkcionalne skupine fitoplanktona u kojima su vrste tolerantne na stresne uvjete. Sušno razdoblje u kolovozu bilo je karakterizirano masovnim razvojem invazivne vrste Cylindrospermopsis raciborskii. Indeks funkcionalnih skupina fitoplanktona (Q indeks) korišten je u procjeni ekološkog stanja Sakadaškog jezera. Vrijednosti Q indeksa pokazale su da se Sakadaško jezero nalazi u statusu između lošeg stanja u uvjetima bez plavljenja i razvoja vodnog cvijeta cijanobakterija i dobrog stanja u uvjetima dugotrajnih poplava.
Abstract (english)
Extreme floods from the River Danube caused by heavy rainfalls and snow melting are occurring with greater frequency and intensity as a consequence of climate changes. Floodplain ecosystems such as Kopački rit are particularly vunerable to extreme hydrological events. The aim of this study was to assess the influence of extreme flood from the Danube river in spring and summer 2013 on the phytoplankton dynamics in a shallow floodplain lake, Lake Sakadaš (Kopački rit Nature Park). Phytoplankton research was conducted at monthly intervals during the period April-December 2013 in the central part of the Lake Sakadaš. Low phytoplankton biomass and dominance of species belonging to the functional groups tolerant to stress was found in the conditions of extremly high flooding in Jun 2013. The dry phase in late summer was characterised by mass development of invasive species Cylindrospermopsis raciborskii. Phytoplankton assemblage index (Q index) was applied in the evaluation of ecological status of Lake Sakadaš. Values of Q index showed that Lake Sakadaš was in ecological status between bad, in conditions without flooding, and good in conditions with high flooding
