Abstract
Stvaranje cista kod dinoflagelata moguće je iz dva razloga: (1) kao sastavni dio životnog ciklusa i (2) kao mehanizam preživljavanja nepovoljnih uvjeta. Glavni vektor prijenosa cista dinoflagelata su balastne vode. U području Riječkog zaljeva izabrano je 5 postaja na kojima je provedeno uzorkovanje tijekom 2011., 2014. i 2015. godine. U uzorcima su identificirane 32 vrste cista koje su svrstane u 5 redova. Primjećena je sezonalna distribucija ukupne abundancije cista, kao i sezonalnost kod pojedinih vrsta. Za ciste s većom abundancijom pretpostavlja se da se formiraju iz vegetativnih oblika prisutnih u vodenom stupcu, bilo da su prisutne u fitoplanktonskoj zajednici područja (autohtone vrste) ili su donesene balastnim vodama te su proliferirale (alohtone vrste). Za ciste s manjom abundancijom koje su nađene sporadično vjeruje se da su donesene balastnim vodama. U svrhu boljeg razumijevanja sastava i dinamike populacija cista u Riječkom zaljevu potrebna su dodatna istraživanja,uključujući i ona vezana uz biotičke i abiotičke čimbenike u Riječkom zaljevu.
Abstract (english)
Encystment of dinoflagellate cysts is driven by two major factors: (1) species life cycle and (2) a resistant stage to overcome unfavourable conditions. The main vector for spreading of the cysts is by ships' ballast water. In the Rijeka Bay area five stations have been selected for sampling, which was carried out in 2011, 2014 and 2015. In total, 32 species of dinoflagellate cysts, sorted in five orders were identified. A seasonal pattern in the total abundance was observed along with the seasonal pattern of several species. The cysts with higher abundancies are believed to be formed from the vegetative stages, thus considered autochthonous, in the water column, or have been introduced by ballast water and subsequently spread, thus considered alochthonous. The cysts with lower abundancies and the ones that have been recorded desultorily are believed to be introduced by ballast water. In order to 70 further understand the composition and dynamics of cyst populations in Rijeka Bay additional research needs to be conducted in conjunction with experiments on cysts in regards to biotic and abiotic factors characterising the area.
