Bilim<\/a> insanlar\u0131, t\u0131pk\u0131 John Carpenter\u2019\u0131n 1982 yap\u0131m\u0131 \u201cThe Thing\u201d (\u015eey) adl\u0131 korku klasi\u011finde oldu\u011fu gibi, gezegenin donmu\u015f topraklar\u0131ndaki (permafrost) antik canl\u0131lar\u0131 ara\u015ft\u0131r\u0131yor.<\/p>\n

Neyse ki bulunan organizmalar filmdeki \u015fekil de\u011fi\u015ftiren canavar kadar tehlikeli de\u011fil. Ancak ta\u015f\u0131d\u0131klar\u0131 potansiyel tehdit, k\u00fcresel \u0131s\u0131nman\u0131n tehlikeli sonu\u00e7lar\u0131ndan biri olabilir.<\/p>\n

Yeni yay\u0131mlanan bir ara\u015ft\u0131rmaya g\u00f6re, yakla\u015f\u0131k 40 bin y\u0131ld\u0131r donmu\u015f halde bulunan mikroorganizmalar, Arktik b\u00f6lgelerdeki s\u0131cakl\u0131k art\u0131\u015f\u0131yla birlikte yeniden etkinle\u015firse, atmosfere karbondioksit ve metan salarak iklim krizini daha da derinle\u015ftirebilir.<\/p>\n

YER\u0130N 100 METRE ALTINDAK\u0130 T\u00dcNELLER<\/strong><\/h3>\n

JGR Biogeosciences dergisinde yay\u0131mlanan ara\u015ft\u0131rman\u0131n ba\u015fyazar\u0131 Tristan Caro ve ekibi, Alaska\u2019n\u0131n merkezindeki Permafrost T\u00fcneli Ara\u015ft\u0131rma Tesisi’nde incelemeler yapt\u0131. Yerin yakla\u015f\u0131k 100 metre alt\u0131na uzanan bu t\u00fcnelin duvarlar\u0131nda, mamut ve bizon kemikleri bile h\u00e2l\u00e2 g\u00f6r\u00fclebiliyor.<\/p>\n

Caro, t\u00fcneldeki ilk izlenimini Popular Mechanics’e \u015fu s\u00f6zlerle anlatt\u0131:
\u201c\u0130\u00e7eri girdi\u011finizde hemen k\u00f6t\u00fc bir koku fark ediyorsunuz. Uzun s\u00fcredir kapal\u0131 kalm\u0131\u015f nemli bir bodrum gibi. Bir mikrobiyolog i\u00e7in bu heyecan verici; \u00e7\u00fcnk\u00fc ilgin\u00e7 kokular genellikle mikroplardan gelir.\u201d<\/p>\n

M\u0130KROPLAR 6 AYDA HIZLANDI<\/strong><\/h3>\n

Ara\u015ft\u0131rmac\u0131lar, son buzul \u00e7a\u011f\u0131ndan kalma mikroplar\u0131n \u00f6rneklerini toplad\u0131ktan sonra, bu \u00f6rneklere a\u011f\u0131r su (d\u00f6teryum) ekleyip s\u0131cakl\u0131\u011f\u0131 12 derece civar\u0131na y\u00fckseltti. Ama\u00e7, gelecekteki iklim ko\u015fullar\u0131nda Alaska yaz\u0131n\u0131 taklit ederek mikroplar\u0131n nas\u0131l tepki verece\u011fini g\u00f6zlemlemekti.<\/p>\n

Ba\u015flang\u0131\u00e7ta mikroplar yava\u015f hareket etti; her 100 bin h\u00fccreden sadece biri bir g\u00fcnde yenileniyordu. Ancak 6 ay\u0131n sonunda mikrobiyal koloniler yeniden yap\u0131lanarak g\u00f6zle g\u00f6r\u00fclebilen biyofilm tabakalar\u0131 olu\u015fturdu. Bu antik organizmalar, modern mikroplardan farkl\u0131 olsalar da ayn\u0131 derecede aktifti.<\/p>\n

Bu bulgular, bilim insanlar\u0131n\u0131 endi\u015felendiriyor. \u00c7\u00fcnk\u00fc Arktik b\u00f6lgesi D\u00fcnya\u2019n\u0131n geri kalan\u0131ndan d\u00f6rt kat h\u0131zl\u0131 \u0131s\u0131n\u0131yor, yaz mevsimi uzuyor ve s\u0131cakl\u0131klar topra\u011f\u0131n daha derin katmanlar\u0131na ula\u015f\u0131yor. Yine de ara\u015ft\u0131rma, mikroplar\u0131n tamamen \u201cuyanmas\u0131n\u0131n\u201d aylar s\u00fcrd\u00fc\u011f\u00fcn\u00fc g\u00f6steriyor. Yani etkileri uzun s\u00fcreli s\u0131cak d\u00f6nemlerden sonra ortaya \u00e7\u0131kabilir.<\/p>\n

Caro, gelece\u011fe dair \u015fu uyar\u0131y\u0131 yapt\u0131:<\/p>\n

\u201cAlaska\u2019da tek bir s\u0131cak g\u00fcn\u00fcn pek \u00f6nemi yok. As\u0131l tehlike, yaz mevsiminin uzayarak s\u0131cakl\u0131\u011f\u0131n sonbahar ve ilkbahara kadar devam etmesi. Alaska, Sibirya ve di\u011fer kuzey b\u00f6lgelerinde \u00e7ok geni\u015f permafrost alanlar\u0131 var. Biz bunlar\u0131n yaln\u0131zca \u00e7ok k\u00fc\u00e7\u00fck bir k\u0131sm\u0131n\u0131 inceleyebildik.\u201d<\/p>\n<\/div>\n
