Abstract

Popisivanje faune morskih staništa u istočnom dijelu Jadranskog mora nužna je pretpostavka za uspješno planiranje zaštite i gospodarenja u zaštićenim, ali i nezaštićenim područjima. Tema diplomskog rada je popisati faunu unutar livada morske cvjetnice Posidonia oceanica (Linnaeus) Delile na području zaštićenih područja Istarske županije (Nacionalni park Brijuni, Javna ustanova Kamenjak), te nezaštićenih (obalno područje Medulina). Aktivnosti poput sidrenja brodova, ribolova i ronjenja mogu imati pogubne posljedice na livade morskih cvjetnica, te pripadajuću morsku faunu. Najveće srednje vrijednosti broja izdanaka po m2 utvrđene su u NP Brijuni (postaja Pusti(283,33 izdanaka po m2)), a najmanje vrijednosti bile su na postajama Bodulaš i Šekovac u Medulinskom zaljevu koji je izloženiji antropogenom utjecaju. Zbog smanjene gustoće izdanaka sve livade posidonije na istraživanom području spadaju u kategoriju „livade rijetke gustoće“. Ukupno je zabilježeno 208 vrsta, a najveća bioraznolikost faune utvrđena je na postajama Javorika i Verige u NP Brijuni. Najsličnije postaje po utvrđenim vrstama su Gaz (NP Brijuni) i Fenoliga (JU Kamenjak) (97,5%), a najmanje slične postaje su Polje (JU Kamenjak) i Ceja u području Medulina (46,5%). Kod zaštićene vrste periske (Pinna nobilis) niti na jednoj istraživanoj postaji nije utvrđen mortalitet niti ugroženost. Dobiveni podaci iz ovog rada koristit će se za daljnji monitoring ovog staništa koje je predviđeno za zaštitu, te procjenu mogućih negativnih antropogenih utjecaja.

Abstract (english)

Listing fauna of marine habitats in the eastern part of the Adriatic Sea is a prerequisite for successful planning of protection and management in protected and unprotected areas. The aim of the graduate thesis is to list fauna within the Posidonia oceanica meadows in the protected area of the Istrian County (Brijuni National Park, the Public Institution of Kamenjak) and unprotected area (coastal area of Medulin). Activities such as anchoring boats, fishing and diving can have a devastating effect on the seagrass meadows and the associated marine fauna. The highest mean value of the number of shoots per square meter was found in Brijuni National Park (Pusti station (283.33 shoots per square meter), and the lowest values were at the stations Bodulaš and Šekovac in the Medulin Bay which is more exposed to anthropogenic influence. Because of the reduced density of shoots, all Posidonia oceanica meadows in the exploration area fall into the category "meadow of rare density". A total of 208 species were recorded, and the largest biodiversity of the fauna was determined at the Javorika and Verige stations in the Brijuni National Park. The most similar stations based on recorded fauna are Gaz (NP Brijuni) and Fenoliga (JU Kamenjak) (97.5%), while the least similar stations are Polje (JU Kamenjak) and Ceja in the Medulin area (46.5%). Protected shellfish species Pinna nobilis have no mortality or vulnerability at any of the exploration stations. The data obtained from this work will be used for further monitoring of this habitat foreseen for protection, as well as for assessing possible negative anthropogenic impacts.
