Oceanic posidonia Inonyatso kuzivikanwa nebasa rayo kumahombekombe uye nekuda kwayo kutyisidzirwa chinzvimbo. Kune vanhu vazhinji vanoziva kana vakanzwa nezve posidonia oceanica, asi vasingazive kuti nei chaizvo zvakakosha uye nebasa ravanaro.
Chimwe chezvinhu zvekutanga kuziva nezve posidonia oceanica ndechekusiyanisa kubva kugungwa regungwa. Posidonia haisi algae, chirimwa chiri pasi pemvura. Ine michero, maruva, mashizha, hunde nemidzi kunge chirimwa chaicho. Iwe unoda kuziva saka nei zvichikosha kuti uchengetedze?
Oceanic posidonia
Iyo posidonia oceanica chirimwa chiri pasi pemvura chinotumbuka mumatsutso uye chinobereka michero inozivikanwa se "maorivhi egungwa". Icho chemuchina wemifananidzo, ndiko kuti, inoda mwenje wezuva kunyangwe iri pasi pemvura kuti iite photosynthesis. Uye zvakare, posidonia inoparadzirwa mumakungwa ichigadzira uswa hwegungwa.
Rimwe remabasa ane posidonia nderekuti kuva chiratidzo chakanaka chemvura yakachena, sezvo ichigara chete mumvura yakachena. Ivo havapikise zvakanyatsonaka nzvimbo dzakashatiswa, kwete oxygenated, ine yakawanda turbidity kana ine yakawandisa organic chinhu. Icho chirimwa chinogara chiripo cheMediterranean, yakaziviswa World Heritage Saiti neUNESCO mukucherechedza kwayo yakawanda mabhenefiti ezve nharaunda.
Kukosha kweiyo oceanic posidonia
Rimwe remabasa akakosha anopiwa nemasango egungwa Izvo zvinofanirwa kupa biomass uye okisijeni kuti ibudise nzvimbo dzakakodzera dzekupona kwemarudzi mazhinji. Naizvozvo, kana iyo posidonia ichibatsira pakurarama kwemarudzi mazhinji, mahombekombe ayo anowanikwa aya phanerogamu anowedzera misiyano yawo. Iyo ecosystem ine yakawanda misiyano yezvisikwa haina kusimba zvakanyanya kune zvinokanganisa zvinogona kugadzirwa pairi.
Imwe yemabasa makuru epostidonia ndeye iyo yekudzora kukosora kunotambura nemabhichi. Vanoita izvi nekudzikisa huwandu hwetsvina inouya nemafungu achiriteya pamwe chete nenzvimbo dzemahuswa. Uye zvakare, ivo vanogadzira zvipingamupinyi zvinopesana nemafungu. Iwo masango anogadzira pakati pe4 ne20 litita eoksijeni pazuva pazuva rega rega mita, ichiita chimwe chezvinhu zvakakosha zve oxygenation muMediterranean. Chikamu cheiyi okisijeni chakapararira muchadenga chenyika panguva dzehuwandu hwekugadzirwa.
Kana isu tikatanga kuverenga huwandu hwemhando dzinopona nekuda kweposidonia meadows, tine dzinenge mazana mana emiti yezvirimwa uye dzinosvika chiuru chemhuka. Zvese izvi zvipenyu zvine pekugara munzvimbo dze posidonia meadows. Naizvozvo, kuchengetedzwa kwemafuro uku kwakakosha zvakanyanya kana tichida kuchengetedza mamwe marudzi akasara. Grasslands zvakare inzvimbo yakanaka yekuberekesa mhuka senge chipanji, nyeredzi, mollusks, mazana ehove, makungwa egungwa, nezvimwe.
Mazhinji emhando dzinoberekana mumas posidonia meadows vane kufarira kukuru kwekutengeserana, saka kuparadzwa kwavo kwaizotungamira kumatambudziko akakomba muhupfumi hwenharaunda hunorarama kubva kuhove. Kutyaira kwekushanya kwaizorasikirwa nekukosha kwakakura zvakare nekuparadzwa kweposidonia meadows. Inofungidzirwa kuti hupfumi hunobatsira hunogadzirwa nemasango iwo ari pa14.000 euros pahekita pagore.
Chii chinokanganisa posidonia oceanica?
Kushoreka kwenzvimbo dzehuswa kuri kukurumidza zvikuru nekuda kwekukanganisa kunoitwa nevanhu kwadziri. Mhedzisiro senge kusvibiswa kwemazasi, kuwandisa kwezvinhu zvakasikwa (izvo zvinokanganisa kukura chaiko kwemuti) uye kudziya kwemvura yeMediterranean kunokonzerwa nekushanduka kwemamiriro ekunze mimwe yemhedzisiro inoparadza posidonia meadows. Mushure mekupisa kwezhizha, huwandu hwekufa hwakakura kwazvo zvekuti kurasikirwa kwacho hakugone kukanganiswa nekukura, iyo inononoka zvakanyanya.
Chimwe chezviito zvevanhu chinonyanya kuparadza posidonia meadows is trawling trawling. Meadows zvakare anoparadzwa nekuchereredza, kurasa marara, marara anogadzirwa neacaculture, kuvaka kwemahombekombe, zvinokanganisa algae, nezvimwe.
Sezvauri kuona, chirimwa ichi chinonyanya kubatsira kwete kuchidzivirira.
