Abstract
Uspješno uspostavljene stabilne zajednice invazivnih makrobeskralješnjaka, posebno rakušaca imaju snažan utjecaj na zavičajne bentoske zajednice slatkovodnih ekosustava. Na mnogim su mjestima nadjačali ili čak u potpunosti zamijenili zavičajne vrste. Rakušac Dikerogammarus villosus (Skowinsky, 1894) invazivna je strana vrsta iz porodice Gammaridae koja se proširila iz ponto-kaspijskog područja nakon izgradnje kanala Rajna – Majna – Dunav 1992. godine sve do zapadne Europe. Južnim koridorom stigao je i u Hrvatsku gdje se iz Dunava proširio u velike hrvatske rijeke crnomorskog slijeva. Jedna od važnih karakteristika vrste je eurivalentnost, odnosno tolerancija na česte promjene okolišnih čimbenika kao što su temperatura, salinitet i koncentracija otopljenog kisika, što se pokazalo značajnim za širenje vrste uzvodno, bilo pričvršćivanjem za trup plovila ili preko balastnih voda. Kratko generacijsko vrijeme, brzi rast i razvoj, rano spolno sazrijevanje, velika reproduktivna sposobnost i izrazito grabežljivo ponašanje omogućile su vrsti da u vrlo kratkom vremenu postane dominantna u europskim kopnenim vodama gdje utječe na ravnotežu i biološku raznolikost ekosustava
Abstract (english)
Successfully established communities of invasive macroinvertebrates, especially gammarids, have a strong impact on indigenous benthic communities of freshwater ecosystems. Upon their establishment in a novel environment, the frequently displace indigenous species. Dikerogammarus villosus (Skowinsky, 1894) is an invasive alian species from the family Gammaridae which spread from the Ponto-Caspian area after the construction of the Rhine-Main-Danube canal in 1992 all the way to the Western Europe. It also reached Croatia via the Southern Corridor, where it spread from the Danube into the large Croatian rivers of the Black Sea basin. One of the most important characteristics of the species is its eurivalence, also known as tolerance to frequent changes of environmental factors such as temperature, salinity and dissolved oxygen concentration, which enabled the spread of species all over Europe, either by attaching to the hull or over ballast water. Short generation time, rapid growth and development, early sexual maturation, high reproductive ability and extremely predatory behavior have enabled the species to become dominant in European inland waters in a very short amount of time where it affects the balance and biodiversity of the ecosystem.
