Journal ArticleDOI
Zooplankton community and hydrographical properties of the Neretva Channel (eastern Adriatic Sea)
TL;DR: The community was predominantly neritic but the open sea waters were important in structuring the mesozooplankton assemblage at all stations during the autumn–winter period, and small omnivorous copepods dominated regardless of the season.
Journal ArticleDOI
Community structure and seasonal dynamics of tintinnid ciliates in Kastela Bay (middle Adriatic Sea)
Natalia Bojanić,Olja Vidjak,Mladen Šolić,Nada Krstulović,Igor Brautović,Slavica Matijević,Grozdan Kušpilić,Stefanija Šestanović,Živana Ninčević Gladan,Ivona Marasović +9 more
TL;DR: The total tintinnid abundance, the dominant species abundance and the dominance grade increased significantly with increasing trophic state, while the diversity indices decreased, and it is concluded that abundance and dominance may be straight indicators of ecosystem troPHic state.
Journal ArticleDOI
Feeding of adult sprat, Sprattus sprattus, during spawning season in the Adriatic Sea
TL;DR: The most important food items were adults and juveniles of planktonic copepods and decapod larvae, and the maximum values of stomach content were found in the samples collected during afternoon, while the stomachs of fish caught before sunrise were generally empty.
Journal ArticleDOI
Zooplankton in Adriatic port environments: Indigenous communities and non-indigenous species.
Olja Vidjak,Natalia Bojanić,Alessandra de Olazabal,Margherita Benzi,Igor Brautović,Elisa Camatti,Marijana Hure,Lovrenc Lipej,Davor Lučić,Marco Pansera,Marijana Pećarević,Branka Pestorić,Silvia Pigozzi,Valentina Tirelli +13 more
TL;DR: The zooplankton community was analyzed in ten Adriatic ports as part of the port biological baseline surveys carried out within the framework of the BALMAS project and recorded a total of 76 indigenous copepod species and five NIS, among which Parvocalanus crassirostris detected in Šibenik and Rijeka ports and Oithona davisae in Venice port, are new for the AdRIatic.
Journal Article
Environmental drivers of zooplankton variability in the coastal eastern Adriatic (Mediterranean Sea)
Olja Vidjak,Natalia Bojanić,Slavica Matijević,Grozdan Kušpilić,Živana Ninčević Gladan,Sanda Skejić,Branka Grbec,Igor Brautović +7 more
TL;DR: Zooplankton numerical variability primarily responded to seasonal variation in water temperature and spatial variation in salinity, but spatial distribution of the collected data showed that abundances were also linked to chemical and biological parameters generally used as descriptors of water quality.
