Ithimba lesayensi lamazwe ngamazwe, eliholwa yi-Spanish Institute of Oceanography (IEO-CSIC), liqinisekisile okutholakele okuye kwabeka umphakathi wezinto eziphilayo esiqaphile: ukuba khona kwe-macroalga ebomvu I-Asparagopsis taxiformis ogwini lwaseGalicianLokhu kutholakala, osekuvele kubhalwe phansi encwadini ekhethekile i-Bioinvasions Records, kusekelwe endaweni okwakukhona kuyo isampula e-RÃas Baixas ngonyaka ka-2025, okumele ushintsho olukhulu kulokho esasikwazi mayelana nokwanda kwayo ngokwendawo.
Ukubaluleka kwalokhu okutholakele kwesayensi kukhulu kakhulu, njengoba kumelela irekhodi elisenyakatho kakhulu lalolu hlobo kulo lonke ugu lwaseYurophu i-Atlantic. Eqinisweni, ukutholakala kwalo emanzini aseGalician kusho ukuthi yandisa ngamakhilomitha angaphezu kuka-500 Umkhawulo wokusatshalaliswa owaziwayo ngaphambilini, owawuseningizimu yePortugal, weluliwe. Lokhu kushintshela enyakatho kubonisa ukuthi izithiyo zemvelo ezazikade zibambe lezi zilwane zasezindaweni ezishisayo seziqala ukuba buthaka ngenxa yezinguquko endaweni yasolwandle.
Ukuhlonza ama-molecule kohlobo oluhlaselayo
Ngemva kokutholakala kwale sampula, abacwaningi benze ukuhlaziywa okuphelele kwezakhi zofuzo ukuze bathole ukuthi yiluphi uhlobo oluqondile. Imiphumela yama-molecule iqinisekisile ukuthi yiyo okubizwa ngokuthi uhlu lwesibili lwalolu hloboLolu hlobo lwezakhi zofuzo lubakhathaza kakhulu ososayensi bezinto eziphilayo ngenxa yekhono lalo elimangalisayo lokusabalala kanye nokubekezelela kwalo okukhulu kakhulu izimo zemvelo ezahlukahlukene. Lokhu kuqina kwezakhi zofuzo ngokusobala yikho okuvumela ulwelwe oluvela ezimweni ezifudumele ukuba lusinde futhi luzinze emanzini apholile ngokwesiko ogwini lwaseGalician.
U-Eva Cacabelos, umcwaningi eVigo Oceanographic Center kanye nomuntu obalulekile kulolu cwaningo, ukhombisile ukuthi okwamanje kuyinto ebaluleke kakhulu. inani labantu elibonakala sengathi liqalaLesi siphetho sitholakala ngenxa yokuntuleka kwezakhiwo zokuzala kumuntu ohlaziyiwe, okuphakamisa ukuthi ayikakayitholi indawo enkulu yale ndawo. Kodwa-ke, kumelwe sihlale siqaphile, njengoba ukuba khona kwayo nje sekuwuphawu olucacile lokuthi ukufudumala komhlaba kanye nokuhamba kwemikhumbi okungapheli kushintsha kanjani isimo sezinto eziphilayo zethu.
Ukushisa kwamanzi njengomshayeli woshintsho
Ukufika kwale macroalga, edabuka esifundeni sase-Indo-Pacific futhi esesivele sidale umonakalo eMedithera naseningizimu yeSpain, akuyona into eyenzeka yodwa. Ochwepheshe baxhumanisa lokhu kuhamba kwabantu abafudukayo ngqo ne- ukwanda kokushisa kwamanzi amaningi kanye nokuvama kwamagagasi okushisa olwandle, izinto ezenza buthaka ukuzivikela kwezinhlobo zezinto eziphilayo zendawo. Lapho ulwandle lufudumala, kuvuleka ithuba lokuthi izinhlobo zasezindaweni ezishisayo zithole ikhaya elisha ezindaweni ezazingafanele ukuhlala kuzo ngaphambili.
Ngaphezu kwezimbangela zesimo sezulu, imisebenzi yabantu idlala indima ebalulekile kule nqubo yokuhlakazeka. Kungakhathaliseki ukuthi ngokusebenzisa amanzi aqinile emikhumbi emikhulu noma ngokuhamba ngengozi ngemishini yokuqondisa, lezi zinhlobo zithola ukuthi imizila yokuhlakazeka yokwenziwa okubenza bakwazi ukuhlala ezindaweni ezintsha ngesikhathi esinqunyiwe. Lokhu kuhlanganiswa kwezici kugcizelela isidingo sokuqapha njalo ukuvimbela ibhalansi yolwandle ukuthi ingaphazamiseki ngokungenakulungiseka.
Ingozi yokuhlaselana kanye nokuncintisana nge-substrate
Elinye lamaphuzu akhathaza kakhulu ithimba le-IEO-CSIC kanye nabalingani babo abavela emanyuvesi aseCádiz naseMálaga yisimo sokuhlasela ngokubambisana. Olunye uhlobo olunamandla kakhulu oluvela kwamanye amazwe, iRugulopteryx okamurae, selutholakale ogwini lwaseGalician, futhi ukuba khona kokubili kungaba inhlanganisela eqhumayo. Uma lawa ma-macroalgae amabili ekwazile ukulawula phansi kolwandle Ngesikhathi esifanayo, izinto eziphilayo zasendaweni ezingaphansi komhlaba zazizosuswa, okushintsha kakhulu lonke uchungechunge lokudla lwendawo.
Ikhono lalezi zinhlobo ze-algae lokumboza izindawo ezinkulu ezinamadwala nokususa izinhlobo zendawo libeka usongo oluqondile ekudobeni nasekuvuneni izimbaza, imikhakha ebalulekile yomnotho waseGalician. Ngakho-ke, ucwaningo lugcizelela ukuthi ukutholwa nokuqapha kusenesikhathi Lawa amathuluzi amahle kakhulu okubikezela imiphumela yemvelo. Iphrojekthi ye-GuardIAS, exhaswe uhlelo lwe-European Horizon Europe, isebenza ngokunembile ngale ndlela ukuvikela amanzi aseYurophu ezinhlotsheni zezilwane ezihlaselayo.
Izinhlelo zokuqapha nokuphatha eGalicia
Uhulumeni wesifunda usuvele uthatha isinyathelo sokulawula ukusabalala kwezitshalo ezihlaselayo. UMnyango Wezolwandle usebenzise amasu ahlukahlukene, njengoHlelo Lokuphathwa Kwe-Biomass, ukuqinisekisa ukuthi izinto ezisusiwe emabhishi nasezindaweni zokukhiqiza azibuyeli olwandle. Ngaphezu kwalokho, kunikezwa imali ebalulekile, njenge- Ama-euro ayizigidi eziyi-1,9 abekelwe ukulawula zalolu hlobo lwezinhlobo ezindaweni zokuhlala ezisogwini, befuna ukunciphisa umthelela ezindaweni zokuvunwa kwezinhlanzi.
Kule mpi, ukubambisana kwezakhamuzi kanye nomkhakha wokudoba nakho kubalulekile. Amapulatifomu afana neRedogal avumela abadobi ngokwabo ukuthi baphakamise intukuthelo lapho bethola okuthile okungavamile ezimpahleni zabo, okunikeza isizindalwazi somphakathi esibalulekile kososayensi. Ngenxa yezinhlelo ezifana ne- Iphrojekthi ye-Algasdet kanye nokusetshenziswa kwezimpawu zama-molecule Ngenxa ye-DNA yemvelo, sekulula kakhulu manje ukubona ukuthi kukhona yini lawa ma-algae ngisho nasenhlabathini, okuvumela ukuthi kuthathwe isinyathelo ngaphambi kokuba ukuhlasela kube sobala kakhulu.
Ukuqoshwa kwalesi sibonelo sokuqala se-Asparagopsis taxiformis ngo-2025 kuyingqophamlando yesayensi esisiphoqa ukuthi sicabange kabusha ngobuthakathaka bezindawo zethu zemvelo ezinesimo sezulu esipholile. Nakuba kusesenesikhathi kakhulu ukwazi ukuthi le macroalga izokwazi yini ukwakha imiphakathi ezinzile nehlala njalo, ikhono layo loku ukuphazamisa ukusebenza kwemiphakathi yasolwandle Lokhu kuyiqiniso elivele libonwe kwezinye izifunda. Ukugcina imizamo yocwaningo kanye nokuqapha okuqhubekayo kuzobaluleka ekuvikeleni ukuceba kwezinto eziphilayo zemifula yethu lapho sibhekene nezinselele ezibangelwa ulwandle olushintsha njalo.
