Abstract
Rasprostranjenost rebraša Mnemiopsis leidyi je do 1980-tih godina bila ograničena na područje atlantske obale Sjeverne i Južne Amerike, nakon čega se vrsta proširila balastnim vodama u Crno more, a zatim postupno i u Azovsko more, Kaspijsko jezero, Sredozemno more te Sjeverno i Baltičko more. U radu su opisani podrijetlo i dinamika invazije M. leidyi te biološko-ekološke značajke ove vrste. Mnemiopsis leidyi nastanjuje priobalne vode umjerenih mora gdje postiže najveću biomasu i dominira planktonskim zajednicama u toplom dijelu godine s izraženim sezonskim promjenama. Genetske studije pokazuju da je do invazije u euroazijske vode došlo iz dva područja: populacija iz Crnog mora potječe iz Meksičkog zaljeva dok su Sjeverno i Baltičko more kolonizirani jedinkama iz Nove Engleske. Zahvaljujući prekooceanskom prijevozu, predviđa se nastavak širenja Mnemiopsisa a kakav će utjecaj imati na novi ekosustav ovisi o različitim abiotičkim čimbenicima, lokalnim strujama te prisustvu ili odsustvu prirodnih predatora.
Abstract (english)
Distribution of a ctenophore Mnemiopsis leidyi was until 1980s limited to the Atlantic coast of North and South America, after which the species spread by ballast waters into the Black Sea, then progressively to Azov Sea, Caspian Sea, Mediterranean Sea, North and Baltic Sea. In this thesis, the origin and dynamics of M. leidyi invasion and the biological – ecological features of this species are described. Mnemiopsis leidyi inhabits coastal temperate waters where it achieves the highest biomass and dominates the planctonic communities during the warm season with notable seasonal changes. Genetic studies demonstrated that the invasion of Euroasian waters had two origins: the Black Sea population originated from the Gulf of Mexico, while the North and Baltic Sea were colonized by individuals from New England. Due to continuing transport by transoceanic shipping it is anticipated that M. leidyi will continue to expand. The impact the species elicits on the invaded ecosystem depends on various abiotic factors, local curents and the presence or absence of natural predators.
