IMeditera iCystoreira lolona hlobo luchaphazeleka kakhulu kukutshintsha kwemozulu

I-cystoseira yaseMeditera

Asizizo zonke iintlobo ezinobungozi ngokulinganayo kutshintsho lwemozulu. Kuxhomekeke kubume bomzimba, ikhosistim apho ikhoyo kunye nemozulu kunokwenzeka ukuba ichaphazeleke okanye hayi. Kule meko siza kuthetha ngayo iMeditera yaseCystoseira, isalga esona sisityalo sichaphazeleka kakhulu kukunyuka kwamaqondo obushushu abangelwa lutshintsho lwemozulu.

Ichaphazeleka njani le alga?

ICystoseira mediterranea

ingca yolwandle iMeditera

I-cystoseira mediterranea sisilwanyana esiphambili se-algae esifumaneka kulwandle. Ngokophando lwamanye amazwe apho abaphandi abavela kwiZiko leMeditera leziFundo eziPhambili, i-Imedea (i-UIB-CSIC) ithathe inxaxheba, le alga inokuba abona bantu bachaphazeleka kakhulu kukunyuka kwamaqondo obushushu bamanzi obangelwe kukufudumala komhlaba.

Xa amaqondo obushushu enyuka elwandle naselwandle, unxibelelwano phakathi kweentlobo luyachaphazeleka. Indalo inebhalansi ehlala kutshintshiselwano lwento kunye namandla phakathi kweentlobo ezihlala kwindalo. Nangona kunjalo, xa iimeko zitshintsha (njengoko kunjalo nakumaqondo obushushu anyukayo), unxibelelwano phakathi kweentlobo lunokujika ubume nokwakheka kwezinye zezinto eziphilayo ezibaluleke kakhulu.

Iimpembelelo kwiMeditera

iiurchins zolwandle

Uphononongo olwenziwe luqinisekile ngokubhekisele kwiibhedi zengca yolwandle yeentlobo ezingenakubuyiseka ezinje ngePosidonia, ubuncinci ngokubhekisele kwiziphumo zezityalo ezitya utyani.

Kodwa ukwabonisa ukuba le alga iphakathi kweentlobo eziza kuchaphazeleka kakhulu. Ulwandle lweMeditera Sele inyusa ubushushu bayo ngenxa yobushushu behlabathi. Uluntu oluninzi lwe-algae kwiMeditera lusemngciphekweni wokuchaphazeleka zizityalo ezinjenge-hedgehog, ezinokuthi zinciphise inani labantu.

Umsebenzi opapashwe kwiphephancwadi elithi "Marine Pollution Bulletin" uhlalutye izinto ezinokuba nefuthe ekusebenzisaneni kwezityalo nezityalo, ukuzama iintlobo ezintathu zezona zibalulekileyo zezityalo zaseMeditera: iPosidona oceanica kunye neCymodocea nodosa izityalo kunye neCystoseira mediterranea alga , kunye nomthengi oqhelekileyo, urchin yolwandle, iParacentrotus lividus.

Iziphumo zolu phononongo zibonisa ukuba ii-herbivores zibeka uxinzelelo ngakumbi kwiintlobo ezimbini zezityalo kwaye abantu baya kuhlala befana nokufudumala komhlaba. Ikwabonisa ukuba banokuncitshiswa ukusukela ezi zityalo ziyakwazi ukuvelisa iikhompawundi ezinobungozi okanye engathandekiyo kwizityalo ezitya utyani xa zikhulile kumanzi ashushu.

Ukuncitshiswa kwenqanaba lokukhula

Nangona kunjalo, xa beqhubeka nokufunda i-algae, bayaqonda ukuba amaqondo obushushu aphezulu anciphisa izinga lokukhula, nangona ukusetyenziswa kwabo yi-hedgehog kuhlala kuphezulu kakhulu.

Oososayensi bayayithatha imeko iyakhathaza kuba ukugqithisa ngokugqithileyo kwii-urchins sele kunefuthe elibalulekileyo kumahlathi e-kelp, ukuze, ukuba zichaphazeleka ngamaqondo obushushu aphezulu, kunokubonakala "Iintlango eziphantsi kwamanzi", Oko kukuthi, indawo yamatye ngaphandle kwe-algae.

Inani le-hedgehog likhula ngakumbi nangakumbi kwaye lichaphazela iindawo ezithile kwintshona yeMeditera. IiHedgehogs ziyakhula ngenxa yokungabikho kwezilwanyana ezizingelayo ezibangela ukuloba okungaphezulu kwabantu.

Njengokuba utshintsho lwemozulu luchaphazela yonke i-ecosystem xa iyonke, kufuneka siqonde ukuba amandla okudibana kwezi ntlobo ziya kutshintsha. Unxibelelwano Zibalulekile kwindalo ukuze zikhule kakuhle ngakumbi kwiindawo ezinjengeMeditera, indawo evaliweyo.

Umphandi we-CEAB-CSIC kunye nentloko yeprojekthi ye-RECCAM, u-Teresa Alcoverro, wagxininisa ukuba, ngokophando, "ayizizo zonke iziphumo eziya kuba zibi" kunye neentlobo ezinje nge Posidonia, "nangona zingakhuselekanga kwiziphumo zeqondo lobushushu, ewe ubuncinci kubonakala ngathi bazokwazi ukumelana kakuhle nefuthe lezilwanyana ezitya utyani ”.

Isifundo sisiphumo sentsebenziswano phakathi kwabaphandi abavela kwiZiko loPhuculo oluPhambili lweBlanes (CSIC), iYunivesithi yaseBarcelona, ​​iImedea, iYunivesithi yaseOregon State (iUSA), iDeakin University (Australia), iZiko loLondolozo lweNdalo (eIndiya) kunye neYunivesithi yaseBangor (Wales, UK) ngaphakathi kwesakhelo seprojekthi ye-RECCAM.

Njengoko ubona, i-ecosystems inovakalelo kakhulu kwaye unxibelelwano phakathi kweentlobo luyimfuneko.
