Abstract

Cilj ovoga rada pojasniti je što su invazivne vrste. Većina invazivnih vrsta dijele određene karakteristike poput brzog razmnožavanja, rasta i razvoja, velikog broja potomaka, kratkog generacijskog perioda te otpornosti i prilagodljivosti na različite uvjete. Te karakteristike im omogućuju rapidno širenje i kolonizaciju novih staništa, često na štetu organizama koji su nativni za ta područja. Natječući se s autohtonim vrstama za hranu i prostor, invazivne vrste polako ali sigurno sudjeluju u odumiranju vrsta i drastičnom smanjenju bioraznolikosti. U radu su navedeni primjeri nekih vrsta koje su postale invazivne u Sredozemnom moru, njihova obilježja i opasnosti koje predstavljaju. Također su spomenute metode kontroliranja, suzbijanja i uklanjanja tih vrsta iz koloniziranih područja. Univerzalna metoda borbe protiv alohtonih vrsta i njihova istrebljenja ne postoji, već se za svaku vrstu ili skupinu vrsta koje dijele određena svojstva koristi najprikladnija metoda. Mediteran je jedinstveno more, danas je njegov živi svijet vrlo ugrožen, između ostalih prijetnji i napredovanjem invazivnih vrsta. Zato je važno da se ovom problemu da prioritet i da se nađu efikasna i sigurna rješenja.

Abstract (english)

This paper tackles the subject of marine invasive species. Many invasive species share a number of common traits and characteristics that help them survive and thrive in a new habitat, often directly damaging the existing populations of native species in the colonized habitat. These traits, such as rapid reproduction, large numbers of offspring and the ability to adapt to a number of environmental conditions give these species an edge over native ones, which often results in diminishing of marine biodiversity, and in some cases even local extinction of certain species that are in direct competition with the invaders. The paper also presents some examples of invasive species that can be found in the Mediterranean Sea, describing their traits and explaining what makes them invasive and therefore dangerous for the environment, and potentially humans. Some methods for control, management and eradication of marine invasive species are also described. It should be noted that no method is universal, and depending of the species' characteristics, the method thought to be most effective is chosen accordingly. Mediterranean is unique enclosed sea and its biota is highly endangered. Invasive species advancement is one of the numerous threats and it is important that this problem should be given priority in order to obtain effective and safe solutions.
