Chikwata chesainzi chepasi rose, chinotungamirwa neSpanish Institute of Oceanography (IEO-CSIC), chakasimbisa zvakawanikwa zvakaita kuti nharaunda yezvisikwa irambe yakangwarira: kuvapo kwered macroalga Asparagopsis taxiformis pamhenderekedzo yegungwa reGalicianKuwanikwa uku, uko kwatove kwakanyorwa mubhuku rakasarudzika reBioinvasions Records, kwakavakirwa panzvimbo yemuenzaniso muRÃas Baixas mugore ra2025, izvo zvinomiririra shanduko huru mune zvataiziva nezvekukura kwayo munzvimbo.
Kukosha kwekuwana uku kwesainzi kwakakura, sezvo kuchimiririra chinyorwa chekuchamhembe chemhando iyi pamhenderekedzo yese yeAtlantic yeEurope. Kutaura zvazviri, kuwanikwa kwayo mumvura dzeGalician kunoreva wedzera daro rinodarika makiromita mazana mashanu Muganho wekupararira kwemhuka waimbozivikanwa kare, waive kumaodzanyemba kwePortugal, wawedzerwa. Kuchinja uku kwekuchamhembe kunoratidza kuti zvipingamupinyi zvechisikigo zvaimbodzivirira zvipenyu izvi zvemunzvimbo dzinopisa zviri kutanga kushaya simba nekuda kwekuchinja kwenzvimbo dzemugungwa.
Kuzivikanwa kwemamorekuru kwemhando yemusanganiswa inopararira
Mushure mekuwanikwa kwemuenzaniso uyu, vaongorori vakaongorora majini zvakakwana kuti vaone kuti waive rudzii chaizvo. Zvakabuda mumamorekuru zvakaratidza kuti ndiwo inonzi dzinza rechipiri rerudzi urwuRudzi urwu rwemajini runonetsa zvikuru vanoongorora zvipenyu nekuda kwekugona kwarwo kuberekana uye kushivirira kwarwo zvakanyanya kune mamiriro akasiyana-siyana ezvakatipoteredza. Kusimba kwemajini uku ndiko kuri pachena kuti kunoita kuti alga inobva mumamiriro ekunze anodziya irarame uye igare mumvura inotonhorera yegungwa reGalician.
Eva Cacabelos, muongorori paVigo Oceanographic Center uye munhu akakosha muongororo iyi, akaratidza kuti parizvino inyaya ye " huwandu hwevanhu hunoita sehunotangaMhedziso iyi inobva mukushaikwa kwezvimiro zvekubereka mumunhu akaongororwa, zvichiratidza kuti haisati yasvika pakukura kwenzvimbo iyi. Zvisinei, tinofanira kuramba takangwarira, sezvo kuvapo kwayo chete kwatova chiratidzo chakajeka chekuti kudziya kwepasi rose uye kufamba kwegungwa kusingaperi kuri kuchinja sei mamiriro ezvakatipoteredza zvedu.
Kudziisa mvura senzira yekuchinja zvinhu
Kusvika kwegungwa guru iri, iro rinobva kunharaunda yeIndo-Pacific uye rakatokonzera nyonganyonga muMediterranean nekumaodzanyemba kweSpain, hachisi chiitiko chega. Nyanzvi dzinobatanidza kufamba uku kwegungwa zvakananga ne kuwedzera kwekupisa kwemvura uye kuwanda kwemafungu emvura anopisa mugungwa, zvinhu zvinoderedza dziviriro yezvisikwa zvipenyu zvemuno. Kana gungwa radziya, mukana wekuti mhuka dzinopisa dziwane musha mutsva munzvimbo dzaisambofa dzakambodzifarira.
Kuwedzera kune zvinokonzera mamiriro ekunze, mabasa evanhu ane basa guru mukupararira uku. Ingava kuburikidza nemvura yekufambisa ngarava huru kana netsaona nemidziyo yekufambisa, mhando idzi dzinoona kuti nzira dzekuparadzira dzekugadzira izvo zvinovabvumira kugara munzvimbo itsva munguva pfupi iri kutevera. Kusanganiswa uku kwezvinhu kunoratidza kudiwa kwekuramba vachingwarira kudzivirira kuenzana kwegungwa kuti kusadzorerwe zvachose.
Njodzi yekupindirwa pamwe chete uye kukwikwidzana kwe substrate
Chimwe chezvinhu zvinonyanya kunetsa timu yeIEO-CSIC nevanoshanda navo kubva kumayunivhesiti eCádiz neMálaga chiitiko chekupararira pamwe chete kweshiri. Imwe mhando yeshiri ine hukasha, Rugulopteryx okamurae, yatoonekwa pamhenderekedzo yegungwa reGalician, uye kugara pamwe chete kweshiri mbiri idzi kunogona kuva musanganiswa unoputika. Kana idzi macroalgae mbiri dzikakwanisa kutonga pasi pegungwa Panguva imwe chete, zvisikwa zvemuno zviri mugungwa zvaizobviswa, zvichichinja zvikuru cheni yese yekudya munzvimbo iyi.
Kukwanisa kwealgae idzi kufukidza nzvimbo dzakakura dzine matombo uye kubvisa mhuka dzemuno kunokonzera njodzi huru kuhove nekukohwa hove dzegungwa, zvikamu zvakakosha zvehupfumi hweGalician. Nokudaro, tsvakurudzo inosimbisa kuti kuonekwa nekukurumidza uye kutariswa Izvi ndizvo zvishandiso zvakanakisisa zvekutarisira kukanganisa kwezvakatipoteredza. Chirongwa cheGuardIAS, chinotsigirwa nechirongwa cheEuropean Horizon Europe, chinoshanda nenzira chaiyo kudzivirira mvura dzemuEurope kubva kumarudzi ezvisikwa anopararira.
Zvirongwa zvekutarisa nekutarisira muGalicia
Hurumende yedunhu iri kutotora matanho ekudzora kupararira kwemiti inopararira. Bazi reGungwa rakatanga matanho akasiyana-siyana, akadai seBiomass Management Plan, kuona kuti zvinhu zvakabviswa kubva kumahombekombe nenzvimbo dzekugadzira hazvidzokeri kugungwa. Uyezve, mari yakawanda iri kugoverwa, senge 1,9 miriyoni euros yakagoverwa kutonga mhando iyi yemhando dzemhuka dziri munzvimbo dziri pamhenderekedzo yegungwa, vachiedza kuderedza kukanganisa nzvimbo dzinokohwewa hove dzegungwa.
Muhondo iyi, kushanda pamwe chete kwevagari nebazi rezvekubata hove kwakakoshawo. Mapuratifomu akaita seRedogal anobvumira vabati vehove pachavo kuti vataure kana vawana chimwe chinhu chisingawanzoitika mumidziyo yavo, vachipa database yeruzhinji yakakosha kune vesainzi. Nekuda kwezvirongwa zvakaita se Chirongwa cheAlgasdet nekushandiswa kwemamaki emolekyulu Nekuda kweDNA yezvakatipoteredza, zvava nyore kuona kuvapo kwealgae idzi kunyangwe mumatope, zvichiita kuti chiito chitange chatorwa kusati kwanyanya kuoneka.
Kunyorwa kwemuenzaniso wekutanga weAsparagopsis taxiformis muna 2025 kunoumba danho resainzi rinotimanikidza kufunga patsva nezvekushaya simba kwezvakatipoteredza zvedu zvine mwero. Kunyangwe zvichiri kutanga kuziva kana macroalga iyi ichakwanisa kuumba huwandu hwakagadzikana uye hwechigarire, kugona kwayo kuita kukanganisa mashandiro enharaunda dzemugungwa Izvi ndizvo zvatoonekwa mune dzimwe nzvimbo. Kuramba tichiita tsvakurudzo uye kugara tichitarisa zvichave zvakakosha pakuchengetedza hupfumi hwenzvimbo dzedu dzegungwa pasinei nematambudziko anokonzerwa negungwa rinogara richichinja.
