Abstract
Seagrass meadows are extremely important as primary producers and as a habitat. They stabilize the substrate and protect the coastline from the erosion. They have enormous potential to trap carbon from the atmosphere so they act as a carbon sink. Seagrass loss is present worldwide due to anthropogenic activities and also climate change. Sediment burial of seagrass is one of the reasons for global seagrass decline. This research used videography method to document changes in sediment accumulation, seagrass density and ground coverage in western part of Novigrad Sea in time period from 2009 to 2011. Changes found in sediment accumulation are partially responsible for changes found in seagrass ground coverage. Moreover, this research confirmed the success of the videography method fir seagrass monitoring. Analysis of seagrass samples found vertical rhizome in Zostera marina and Zostera noltei which is a unique report for Z. marina and second report in the world for Z. noltei. Vertical rhizome is probably induced by sediment burial in the studied area caused by strong E-NE winds and this morphological feature can be interpreted as a local adaptation for burial tolerance of this seagrass population. Seagrass samples collected in the area with higher sediment accumulation rate showed higher belowground biomass which indicates the development of large anchoring system to better cope with hydrodynamic activity. Data gathered through this research can help improve the management of studied Natura 2000 area.
Abstract (croatian)
Livade morskih cvjetnica iznimno su značajne kao primarni proizvođači i stanište, važan je njihov utjecaj na stabilizaciju supstrata i zaštitu obale od erozije te su vrlo učinkovite u uklanjanju CO2 iz atmosfere te predstavljaju spremišta ugljika. Zbog sve većeg pritiska antropogenog djelovanja i klimatskih promjena, morske cvjetnice nestaju diljem svijeta. Također, zatrpavanje morskih cvjetnica sedimentom jedan je od ključnih razloga njihovog nestajanja. Istraživanje provedeno za potrebe ove disertacije koristilo je metodu videografije kojom se zabilježila neto akumulacija sedimenta te gustoća morskih cvjetnica u zapadnom dijelu Novigradskog mora i promjene u pokrovu morskog dna u razdoblju 2009. – 2011. g. Uočene promjene u akumulaciji sedimenta djelomično su odgovorne za promjene nastale u pokrovu dna morskim cvjetnicama. Također, ovo istraživanje potvrdilo je uspješnost upotrebe metode videografije za praćenje promjena naselja morskih cvjetnica. Analizom prikupljenih uzoraka morskih cvjetnica Zostera marina, Zostera noltei i Cymodocea nodosa otkriven je vertikalni rizom kod vrsta Zostera marina i Zostera noltei što je jedinstveni nalaz sa vrstu Z. marina te tek drugi nalaz u svijetu za vrstu Z. noltei. Vertikalni rizom je vjerojatno induciran zatrpavanjem sedimentom uzrokovanim sjevernim i sjeveroistočnim vjetrovima, a ova morfološka osobina može se tumačiti kao lokalna adaptacija istraživane populacije morskih cvjetnica na zatrpavanje sedimentom. Uzorci morskih cvjetnica prikupljeni u području s većom stopom akumulacije sedimenta imali su veću podzemnu biomasu što upućuje na razvoj većeg “sustava sidrenja” kojim se cvjetnice pričvršćuju za dno kako bi bolje podnijele jače hidrodinamičke uvjete. Prikupljeni podaci mogu doprinijeti boljem upravljanju istraživanog Natura 2000 područja.
