PRAVILA PONAŠANJA CODE OF CONDUCT PRAVILA PONAŠANJA CODE OF CONDUCT OCEANSKI POROST NEPTUNE GRASS (POSIDONIA OCEANICA) Oceanski porost, posidonija ili voga (Posido- nia oceanica) je morska cvjetnica koja ima puzavu, položenu stabljiku (rizom), korije- njem pričvršćenu uz podlogu. Iz rizoma se uz- dižu izdanci koji nose 4 do 8 listova u snopiću. Ima duguljasto i jednostavno lišće, u prosjeku dugo 30 do 80 cm, a široko oko 1 cm. Neptune grass (Posidonia oceanica) is a sea- grass species with a creeping laid stem (rhi- zome), which is aached to the base by small roots. Out of the rhizome rise shoots carry - ing bundles of four to eight leaves. Neptune grass has elongated and simple leaves, on av - erage 30 to 80 cm long, and approximately 1 cm wide. Livade oceanskog porosta „tvornice“ su kisika i „spremnici“ bioraznolikos. U njima se mnoge vrste hrane, razmnoža - vaju i nalaze zaklon. Svojim ispreplete - nim položenim stabljikama (rizomima) i uspravnim izdancima smanjuju odno - šenje sedimenta djelovanjem morskih struja; važne su i za kruženje hranjivih soli u moru. Livade oceanskog porosta vrijedan su ekosustav Sredozemlja, a tako i Jadrana, koji moramo sačuva. Neptune grass meadows are “oxygen factories” and “storage” of biodiversity. Many species feed, reproduce and find shelter in them. With their interwoven, laid stems (rhizomes) and vercal shoots, they decrease the depleon of sediment due to sea currents, and are also important for sediment nutrient cycling in the sea. Neptune grass meadows are a valuable ecosystem of the Mediterranean, and also of the Adriac, which we must preserve. Živi samo u Sredozemnom moru (endemska vrsta). Gradi morske livade koje se protežu na sedimentnim dnima, a može se naći i u pukonama sjena u kojima se istaložilo do- voljno sedimenta. Nastanjuje područja s vi- sokom prozirnošću mora, tj. do dubine do koje dopire Sunčeva svjetlost. U sjevernom Jadranu, gdje je manja prozirnost vodenog stupca, livade sežu najviše do 20 m dubine, a u Južnom Jadranu i do oko 50 m. Poput kopnenih biljaka, oceanski porost gubi lišće i obnavlja ga svake godine. Ipak vegeta- cijsko razdoblje nešto je drugačije za razliku od kopnenih biljaka: rast se zbiva početkom zime tako da je lišće u kasno ljeto staro i pre- kriveno epifima, tj. organizmima koji žive na njegovim listovima. Krajem ljeta te počet - kom jeseni, odbačeno lišće akumulira se na obali. Neptune grass lives only in the Mediterra- nean Sea (it is an endemic species). The plant grows in sea meadows spreading in soſt boom, and it can also be found in rock cracks with sufficient deposited sediment. The plant is inhabing areas with high sea transparency, i.e. up to the depth penetrated by sunlight. In the northern Adriac, where transparency of the water column is lower, meadows can reach maximum depth of up to twenty meters. In the southern Adriac, meadows may reach depths of as many as fiſty meters. Like land plants, Neptune grass is shedding leaves and growing them again every year. However, the vegetaon season is somewhat different compared to land plants: the growth occurs at the beginning of winter, which means that by late summer the leaves are old and covered by epiphytes – organisms living on plant leaves. Towards the end of summer and the beginning of autumn, the discarded leaves accumulate along the coast. Oceanski porost se najvećim dijelom razmnožava nespolno – otkinum dijelovima položene stablji- ke (rizom). Rjeđe se razmnožava spolno – cvjeta- njem. Biljka cvjeta u kasnu jesen i početkom zime, no ne svake godine. Plodovi oblikom i bojom pod- sjećaju na plodove masline. Kada dozriju, ispluta- ju na morsku površinu, pa ih tako vjetar i morske struje mogu raznije. U svakom je plodu jedna sje- menka, koja nakon raspucavanja usplođa tone na morsko dno i zakorjenjuje se. Odatle će potencijal- no izniknu mlada biljka. Neptune grass is reproducing asexually in most cas- es – via detached roots of the laid rhizome. Sexual reproducon by flowering is a comparavely rare occurrence. The plant is flowering in late autumn and in the beginning of winter, but not every year. The shape of plant fruits is similar to the shape of olives. When they ripen, they float onto the sea surface, and can thus be carried by wind and sea currents. Every fruit contains one seed, which sinks to the sea boom aſter the cracking of the outer layer and grows roots. A potenal new plant can potenally sprout from there. Raste u području gdje je prisak ljudskih akvnos izrazito velik. Sidrenje plovila u oceanskom porostu znatno oštećuje mrežu položenih stabljika (rizoma), koja tada postaje podložna razaranju valova. Osim toga ugrožavaju ga strane invazivne vrste (poput ze- lenih algi roda Caulerpa), onečišćenje otpadnim voda- ma, gradnja i nasipanje u more iznad njegovih naselja, uzgajališta riba i školjkaša, marine, lučice, neki ribo- lovni ala. Zbog važnos livada ove morske cvjetnice te osjetljivos i ugroženos koja im prije, oceanski porost je u Hrvatskoj strogo zašćen Zakonom o zaš prirode. Neptune grass grows in areas where the pressure of hu - man acvies is extraordinarily high. Anchoring of vessels in Neptune grass communies causes significant dama - ge to the laid stem (rhizome) network, which becomes subject to destrucon by waves. In addion, the danger is also posed by invasive alien species (such as seaweed of the genus Caulerpa ), wastewater polluon, and con - strucon and land reclamaon in the vicinity of Neptune grass communies. These communies are also endan - gered by fish and shell culvaon facilies, marinas, lile ports, and some fishing tools. Due to the importance of Neptune grass meadows, their sensivity and the dan - ger they face, Neptune grass is strictly protected in Croa - a by the Law on Nature Protecon. Na pješčanim i šljunčanim obalama često se mogu naći naplavine organskog podrijetla, poput ostataka morskih cvjetnica i raznih alga. U uvali Sakarun do- miniraju naslage odbačenog lišća oceanskog porosta. One su vrlo važne jer pridonose ukupnoj količini organske tvari na samom staništu. Zbog izrazitog kolebanja ekoloških uvjeta te priska ljudskog djelovanja, ta su staništa iznimno osjetljiva. Karakterisčne vrste koje se hrane organskim de- tritusom koji nastaje raspadanjem lišća morske vegetacije su neki račići (npr. Lekanesphaera sardoa, Sphaeroma serratum, Echinogammarus olivii, Talitrus saltator i Orchesa gammarellus), sitni mnogočetonaši (npr. rod Ophelia), sit - ni kukci roda Bledius, kornjaš hitra (Cicindela sp.) i dr. Deposits of organic origin can frequently be encountered on sandy and pebble coast, such as remains of seagrass and various algae. The dominant deposits in Sakarun Bay consist of discarded Neptune grass leaves. These deposits are very important, because they contribute to the total quanty of organic sub- stance in the habitat itself. Due to extraordinary oscillaons of ecological condions, and due to the pre- ssure of human acvies, these habitats are extremely sensive. Characte- risc species feeding on organic detritus resulng from the disintegraon of sea vegetaon leaves include some species of crustacea (e.g. Lekanesphaera sardoa, Sphaeroma serratum, Echinogammarus olivii, Talitrus saltator and Or - chesa gammarellus), small polychaetes (e.g. genus Ophelia), small insects of the genus Bledius, species of beetle (Cicindela sp.), etc. Pojedini listovi oceanskog porosta mogu bi duži od 1 m. Individual Neptune grass leaves can exceed 1 m in width. Jedino još u morima oko Australije žive dvije srodne vrste. Two species related to Neptune grass exist only in the sea around Australia. U livadama oceanskog porosta živi više od 20% poznah morskih vrsta Sredozemnog mora. Over 20% of known marime species of the Mediterranean live in Neptune grass meadows. Zbog sporog rasta, neki primjerci oceanskog po- rosta mogu bi stari i preko 1000 godina, a to ga čini jednim od najdugovječnijih organizama Sredozemlja. Due to their slow growth, some Neptune grass specimens can live over 1000 years! That makes Neptune grass one of the most long-lived organ- isms of the Mediterranean. KAKO IZGLEDA? HOW DOES IT LOOK?
