Abaphandi kwiZiko lase-Australia lezeNzululwazi zaseLwandle benze inkqubela ebonakalayo emfazweni ngokuchasene nesithsaba sameva e-starfish, kwiGreat Barrier Reef.

Inkokheli ephezulu yophando ye-AIMS uGqirha Sven Uthicke kunye nesazi sebhayoloji uJason Doyle, kunye nengcali ye-echinoderm uGqirha Miles Lamare osuka kwiDyunivesithi yase-Otago, eNew Zealand, benze indlela ebiza imali yokufumana iDNA yesilwanyana esitya ikorale.

Ugqirha Uthicke uthe le ndlela izakuphucula ukubekwa kweliso kunye nokufunyanwa kwangoko kwezinambuzane ezikwimilambo, ekwabizwa ngokuba yinkwenkwezi yolwandle enesithsaba, evumela abaphathi bamatye ukuba babe nokuqhambuka kwangoko.

"Yinkqubo yophando yemfuzo ebesiyenzile ukuze sibone imibungu eseastar kwiplankton kwaye siye sakwazi ukuyiguqula le ndlela," utshilo uGqirha Uthicke.

"Sisebenze ngale nto kule minyaka mithathu idlulileyo, kwaye sikwazile ukuyiguqula ukuze ikwenze kube lula ukufumanisa isithsaba sameva sabantu abadala."

Ukubeka esweni imeko yendalo ukuza kuthi ga ngoku akuphumelelanga ukufumana amanqanaba okuqala okuqhambuka okuthintele ukungenelela kwangexesha.

UGqr Uthicke uthe indlela yangoku yokufumanisa uqhambuko yayikukuphononongwa kwamaza aselwandle kusetyenziswa iindlela ezahlukeneyo kodwa ngexesha ezi ndlela zibhaqa ukuqhambuka, uqhambuko luhlala lusekwe kakuhle.

"Iindlela ezisemgangathweni zokujonga zichonga kuphela malunga neepesenti ezintlanu zezinambuzane ezikwimilambo, kodwa le ndlela intsha izakusivumela ukuba sibonise ngokucacileyo ukuba baninzi na abakhoyo," utshilo uGqirha Uthicke.

"Kubalwa inani leekopi zemfuza kwisampulu yamanzi olwandle avela elityeni kusetyenziswa indlela yenoveli ebizwa ngokuba yi-digital droplet PCR."

Ngexesha lomsebenzi wasentsimini wakutshanje, kusetyenziswa iprobe kwiifombo ezili-11 zeGreat Barrier Reef, isithsaba sentyatyambo i-starfish DNA yabonakala kwezo zifo.

Ngokuchasene noko, isithsaba sentshontsho le-starfish ye-DNA lalingekho kwindawo 'yokuqhambuka' emva kokuba abantu bewile, nakwindawo eziphambi kokuqhambuka komhlaba.

Uqhushululu lwesine lokuqhambuka okokoko ngo-1960s lwaqala malunga nowama-2010 kumantla e-Australia kumantla eGreat Barrier Reef kwaye lubone ilahleko ebalulekileyo kukhuseleko lwekorale kwisifiso sokutya se-starfish, isenza igalelo elikhulu kwingxaki yamatye e-coral.

Olu qhambuko lusasazeke emazantsi njenge-Townsville ecaleni kweGreat Barrier Reef, kwaye kulindeleke ukuba iqhubeke emazantsi.

Le projekthi yophando yayixhaswe ngemali yiNkqubo yeSayensi yezeNdalo kuZwelonke (NESP), iGreat Barrier Reef Marine Park Authority kunye nesisa uIan Potter Foundation.
