K\u00f6ln \u00dcniversitesi Zooloji Enstit\u00fcs\u00fc\u2019nden Philipp Schiffer, PLOS Genetics dergisinde detayl\u0131ca anlat\u0131lan bulgunun en \u00e7arp\u0131c\u0131 k\u0131sm\u0131n\u0131n, solucan\u0131n kriptobiyoza katland\u0131\u011f\u0131 s\u00fcrenin uzunlu\u011fu oldu\u011funu s\u00f6yledi.<\/p>\n

Nematodlar gezegenin en yayg\u0131n ya\u015fam formlar\u0131 aras\u0131nda yer al\u0131yor. Bilim insanlar\u0131, baz\u0131lar\u0131n\u0131n s\u0131f\u0131r\u0131n alt\u0131ndaki ortamlarda uzun s\u00fcre ask\u0131da kalarak hayatta kalabildi\u011fini biliyordu. Antarktika’daki bir t\u00fcr\u00fcn, yeniden canland\u0131r\u0131lmadan \u00f6nce donmu\u015f yosun i\u00e7inde 25 y\u0131ldan fazla zaman ge\u00e7irdi\u011fi anla\u015f\u0131ld\u0131\u011f\u0131nda, bunun bir nematod i\u00e7in \u00f6nceki en uzun kriptobiyoz kayd\u0131 oldu\u011fu payla\u015f\u0131ld\u0131. Philipp Schiffer, hi\u00e7 kimsenin bu kadar uzun bir kriptobiyoz s\u00fcrecini tahmin edemedi\u011fini belirtti.<\/p>\n

Schiffer, K\u00f6ln’deki solucan laboratuvar\u0131n\u0131n, ara\u015ft\u0131rmac\u0131lar\u0131n \u201cPanagrolaimus kolymaensis\u201d ad\u0131n\u0131 verdi\u011fi yeni solucan\u0131, genom dizilimi kullanarak analiz edip tan\u0131mlayabildi\u011fini s\u00f6yledi.<\/p>\n

Nematod, bir zamanlar Kutup sincaplar\u0131na ev sahipli\u011fi yapan bir yuvan\u0131n i\u00e7inde, donmu\u015f topra\u011f\u0131n yakla\u015f\u0131k 130 metre derinli\u011finde bulundu.
