Der Guardian berichtet<\/a> von einem innovativen Experiment, das als Hoffnungsschimmer f\u00fcr die bedrohten Korallenriffe weltweit gilt. Wissenschaftler haben eine Kombination aus In-vitro-Fertilisation von Korallen und der \u00dcbertragung von Fischger\u00e4uschen entwickelt, um degradierte Riffe in den Malediven wiederzubeleben. Diese Methode, die in der BBC-Serie “Our Changing Planet” vorgestellt wird, k\u00f6nnte gro\u00dffl\u00e4chig angewendet werden, um sterbende Riffe zu erhalten und zu revitalisieren.<\/p>\n\n\n\n

Was ist In-vitro-Fertilisation von Korallen<\/strong>? Professor Peter Harrison von der Southern Cross University in Australien hat diese Technik entwickelt. Sie beinhaltet das Auffangen von Millionen von Korallenspermien, die entweder an die Meeresoberfl\u00e4che treiben oder durch ein kegelf\u00f6rmiges Netz, das um hitzetolerante Korallen<\/a> gelegt wird, gesammelt werden. Die Gameten vereinigen sich dann, befruchten und bilden Korallenlarven in schwimmenden “Kinderst\u00e4tten”, die sie vor Fressfeinden sch\u00fctzen.<\/p>\n\n\n\n

Wie lockt man die Larven an? Um die Larven dazu zu bringen, sich auf einem degradierten Riff niederzulassen, senden die Wissenschaftler Aufnahmen von Fischger\u00e4uschen aus, die in der N\u00e4he eines belebten, gesunden Riffs aufgenommen wurden. Dies maximiert die Chance, dass die freigesetzten Korallenlarven einen Lebensraum finden, in dem sie das Riff wiederherstellen k\u00f6nnen.<\/p>\n\n\n\n

Die Techniken k\u00f6nnten die Wahrscheinlichkeit, dass Korallen degradierte Riffe wieder besiedeln, erheblich erh\u00f6hen. Angesichts der weltweiten Ereignissen von Korallenbleiche<\/strong> ist dies ein wichtiger Schritt, um die fragilen \u00d6kosysteme zu sch\u00fctzen.<\/p>\n","protected":false},"excerpt":{"rendered":"
