Abstract

Poseban položaj i čistoća Jadranskog mora oduvijek su privlačili razne vrste morskih sisavaca koji su prošli značajan evolucijski put da bi stekli prilagodbe potrebne za život u moru. U ovom radu izložen je pregled najčešćih morskih sisavaca koji žive u Jadranskom moru. Gotovo sve vrste morski sisavaca u Jadranskom moru su ugrožene dok su neke regionalno izumrle i u Jadranskom moru se pojavljuju samo povremeno. Neki od brojnih uzročnika takvog stanja su onečišćenje zbog sve veće litoralizacije koje posebno ugrožava morske sisavce. Degradacija staništa, slučajni ulov u mreže i namjeran lov morskih sisavaca, plastična ambalaža samo su neki od uzroka stvaranja malih i izoliranih populacija koje se bez zaštite ne mogu održati. Stoga je potrebno identificirati mjesta njihove veće brojnosti i direktnim mjerama zaštiti takva područja u cijelosti ili uvesti posebne mjere upravljanja. U protivnom, izgubit ćemo vrste koje čine značajan dio biološke raznolikosti i posebnosti Jadranskog mora.

Abstract (english)

Special position and purity of the Adriatic Sea have always attracted various species of marine mammals that have undergone significant evolutionary path to acquire the necessary adaptations for life in the sea. This work presents an overview of most common marine mammals that live in the Adriatic Sea. Almost all types of marine mammals in the Adriatic Sea are endangered while some are regionally extinct in the Adriatic Sea and appear only occasionally. Some of the many causes of this situation are the growing pollution because of littoralization which is particularly threatened marine mammals. Habitat degradation, accidental entanglement in fishing nets and deliberate taking of marine mammals, plastic packaging are just some of the reasons for the creation of small and isolated populations that can not be maintained without protection. Therefore, it is necessary to identify the places of their greater abundance and with direct measures protect such areas or take specific measures of governance. Otherwise, we will lose species that make up a significant part of biological diversity and specificity of the Adriatic Sea.
