Vatsvagiri veAustralia Institute yeMarine Science vakaita budiriro huru muhondo yekurwisa korona-yeminzwa minzwa hove, paGreat Barrier Reef.
Mukuru wechirongwa cheAIMS Dr Sven Uthicke uye nyanzvi yezvinhu zvipenyu Jason Doyle, pamwe neechinoderm nyanzvi Dr Miles Lamare vanobva kuYunivhesiti yeOtago, kuNew Zealand, vakagadzira nzira isingadhuri yekuona DNA yechipembenene chinodya makorari.
Dr Uthicke vakati nzira iyi ichavandudza kuongorora uye kuona kwekutanga kwechipembenene, icho chinozivikanwa segorona-yeminzwa mhere yegungwa, zvichibvumira mamaneja emvura kuti ave nekuputika nekukurumidza.
"Iyo genetiki yekuongorora iyo yataive tagadzira kuti tione seastar larvae muplankton uye isu takakwanisa kugadzirisa nzira," akadaro Dr. Uthicke.
"Takashanda pane izvi kwemakore matatu apfuura, uye isu takagona kuchinjisa izvi kuti zviite kuti zvinyanye kuona vanhu vakuru korona yeminzwa."
Kuongorora kwekuchengetedzwa kwezvakatipoteredza kusvika parizvino kwakundikana kuona nhanho dzekutanga dzekuputika idzo dzakadzivirira kupindira kwakakodzera panguva.
Dr Uthicke vakati nzira yazvino yekuona kuputika kwaive pamafereferefereferefereti vachishandisa dzakasiyana asi panguva nzira idzi padzinoona kubuda, kuputika kunowanzove kwakasimba.
"Maitiro ekutarisisa akaenzana anongotaridza nezve5 muzana yezvipembenene pamatombo, asi iyi nzira nyowani ichatibvumidza kuti tione zvakajeka kana huwandu hwakawanda huripo," Dr Uthicke vakadaro.
"Inoverenga huwandu hwemakopi emajini mumuenzaniso wemvura yegungwa kubva kugungwa uchishandisa nzira yeruzivo inonzi digitaalinen droplet PCR."
Munguva yebasa remumunda richangoburwa, uchishandisa chiongorori pamatombo gumi nerimwe eGreat Barrier Reef, korona-yemhinzwa starfish DNA yakaonekwa pane avo vanotambura.
Mukupesana, korona-yemhinzwa starfish DNA yakanga isipo kubva ku'mashure-kuputika 'matombo mushure mekuparara kwevanhu, uye kubva kune' pre-kubuda 'matombo.
Mhepo yechina yekumuka kubvira ma1960 yakatanga kutenderedza 2010 kuchamhembe kweAustralia kuchamhembe kweGreat Barrier Reef uye yaona kurasikirwa kukuru kwecoral cover kune yakashata nzara yeiyo starfish, ichiita kuti ive mupiro mukuru kudambudziko remakorari.
Kuputika uku kwakapararira kusvika kumaodzanyemba seTownsville pamwe neGreat Barrier Reef, uye kunotarisirwa kuenderera kumaodzanyemba.
Ichi chirongwa chekutsvaga chakatsigirwa pamwe neNational Environmental Science Chirongwa (NESP), iyo Great Barrier Reef Marine Park Authority uye philanthropist Ian Potter Foundation.
