National Sea Simulator: Chiyembekezo chatsopano cha mtundu wolimba wa ma coral

Ofufuza omwe adayendera bungwe la Australian Institute of Marine Science adzakhala pachimake pazochitika pamene kubadwa kwa ma coral - chimodzi mwazodabwitsa kwambiri padziko lapansi pansi pa madzi - kuyambika sabata ino.

Mitundu yopitilira 18 yamitundu yosiyanasiyana ya coral yakhazikitsidwa kuti itulutse tinthu tating'ono ta chiyembekezo cha matanthwe amtsogolo, mu National Sea Simulator ku AIMS pafupi ndi Townsville.

Katswiri wa za majini wa AIMS, Pulofesa Madeleine van Oppen, adati kafukufuku yemwe achitika ku AIMS sabata ino ndi gawo la pulogalamu ya Reef Recovery yomwe imakhudza kuzizira ndi kusunga umuna wa coral, pofuna kuteteza mitundu yomwe ili pachiwopsezo komanso kusiyanasiyana kwawo.

Prof van Oppen adati National Sea Simulator ndiye malo okhawo ochita kafukufuku padziko lonse lapansi omwe angatsanzire zochitika zoberekera m'malo moyesera.

"Ochita kafukufuku amayenda kuchokera padziko lonse lapansi kukagwira ntchito ku SeaSim ndipo panthawi ya Great Barrier Reef coral spawning nyengo imakhala yotanganidwa nthawi zonse," adatero.

Akatswiri a zaubereki otsogola ochokera ku Taronga Conservation Society Australia, AIMS ndi Smithsonian Conservation Biology Institute yochokera ku US, atolera ndikuwumitsa umuna wa coral, womwe uyenera kusungidwa ngati gawo la malo osungiramo zinthu zakale a Taronga a Great Barrier Reef.

Ofufuza a AIMS atenga zitsanzo za zinthu zopirira kutentha Acropora tenuis nthambi za corals panthawi ya GBR Legacy `Fufuzani Mayankho' ulendo wopita kutali kumpoto kwa Great Barrier Reef, ndikuwasamutsa ndi ndege kupita ku National Sea Simulator AIMS komwe akuyenera kumasula mitolo ya dzira ndi umuna sabata ino.

Wofufuza wa Smithsonian Institute, Dr Jonathan Daly, adati njira zoberekera za anthu zidzagwiritsidwa ntchito kuyesa ngati umuna womwe unatengedwa ndikusungidwa mu 2012, ungathe kubereketsa mazira atsopano kuchokera ku makorali a kumpoto.

"Tabweretsa zitsanzo za umuna wozizira kuchokera kubanki ya Taronga ku Dubbo, NSW kupita ku Townsville, kuti tifufuze momwe cryopreservation ingathandizire ma genetic pa Reef," adatero Dr Daly.

Katswiri wamkulu wa zaulimi ku Taronga Dr Rebecca Hobbs adati kuyesa kwa feteleza komwe kumachitika chaka chino kupangitsa kuti pulogalamu ya Reef Recovery ipitirire kusinthika.

Dr Hobbs adati National Sea Simulator idapereka nsanja yokhazikika yofufuzira yokhala ndi madzi abwino, kutentha kokhazikika komanso kuwala kozungulira, kuti ipange kafukufukuyu.

"SeaSim imalola ma corals kumasula mitolo ya dzira ndi umuna mofanana ndi nthawi yofanana ndi chilengedwe," adatero.

Anati umuna wochokera ku matanthwe a kumpoto olimbawa udzawumitsidwa ndi kutengedwa kupita kubanki yomwe ili kale ndi mitundu 16 ya matanthwe osungidwa m’mabanki awiri a Taronga a CryoDiversity Banks ku Sydney ndi Dubbo.

Pulogalamu ya Reef Recovery inayamba mu 2011, ndi bungwe la Great Barrier Reef Foundation likuthandizira polojekitiyi kuchokera ku 2016, kusonkhanitsa Taronga, Australian Institute of Marine Science ndi Smithsonian Institute, kuti apitirize ntchito yovuta ya cryopreserving Reef ndikupanga bio- gombe la ma coral oundana padziko lapansi.
