Abstract
Potentially toxic diatoms of the genus Pseudo-nitzschia are present in the phytoplankton community of the Adriatic Sea throughout the year, but in the majority of studies identified only to the genus level. The goals of this study was to determine the species composition and morphometric characteristics of the genus Pseudo-nitzschia in the area of Mali Ston Bay (southern Adriatic) from September to December 2022 using scanning electron microscope, and to describe, determine and compare the morphological characteristics of Pseudo-nitzschia species isolated in laboratory cultures from different aquaculture areas of the central and southern Adriatic by light and scanning electron microscopy. A total of 24 laboratory monocultures were analyzed and seven species were determined: Pseudo-nitzschia calliantha, P. cf. delicatissima, P. galaxiae, P. mannii, P. multistriata, P. pseudodelicatissima/cuspidata, and P. subfraudulenta. The analysis of field samples in the Mali Ston Bay revealed seven toxic species P. calliantha, P. cf. delicatissima, P. galaxiae, P. lundholmiae, P. mannii, P. pseudodelicatissima/cuspidata, and P. subfraudulenta. During the study, a change in the species composition of the genus Pseudo-nitzschia was recorded. The species P. pseudodelicatissima/cuspidata predominated in September and October, P. galaxiae in November, while P. subfraudulenta in December 2022. The results of this study represent the first data on the composition of Pseudo-nitzchia in the Maloston Bay.
Abstract (croatian)
Potencijalno toksične dijatomeje roda Pseudo-nitzschia zastupljene su u fitoplanktonskoj zajednici Jadranskog mora tokom cijele godine, ali u većini istraživanja identificirane su do razine roda. Ciljevi ovog rada su odrediti sastav vrsta i morfometrijske karakteristike roda Pseudo-nitzschia na području Malostonskog zaljeva (južni Jadran) od rujna do prosinca 2022. pomoću pretražnosg elektronskog mikroskopa, te opisati, odrediti i usporediti morfološke karakteristike vrsta Pseudonitzschia izoliranih u laboratorijskim kulturama iz različitih akvakulturnih područja srednjeg i južnog Jadrana svjetlosnim i skenirajućim elektronskim mikroskopom. S područja Malostonskog zaljeva i laboratorijskih monokultura s četiri područja duž srednjeg i južnog Jadrana u razdoblju od rujna do prosinca 2022 napravljena je morfološka analiza stanica vrsta roda Pseudo-nitzchia. Ukupno su analizirane 24 laboratorijske kulture te je određeno sedam vrsta: Pseudo-nitzschia calliantha, P. cf. delicatissima, P. galaxiae, P. mannii, P. multistriata, P. pseudodelicatissima/cuspidata, i P. subfraudulenta. Analizom okolišnih uzoraka na području Malostonskog zaljeva određeno je sedam vrsta P. calliantha, P. cf. delicatissima, P. galaxiae, P. lundholmiae, P. mannii, P. pseudodelicatissima/cuspidata, i P. subfraudulenta. Tijekom istraživanja zabilježena je promjena sastava vrsta roda Pseudo-nitzschia. Vrsta P. pseudodelicatissima/cuspidata prevladavala je u rujnu i listopadu, P. galaxiae u studenom, dok je P. subfraudulenta prevladavala u prosincu 2022. Rezultati ovog istraživanja predstavljaju prve podatke o sastavu roda Pseudo-nitzchia na području Malostonskog zaljeva.
