A Live Science szerint ma m\u00e9g valamennyi mikroba a j\u00e9g b\u00f6rt\u00f6n\u00e9ben tal\u00e1lhat\u00f3, \u00e9s ha kiolvadn\u00e1nak, az nem sok j\u00f3t jelentene: felt\u00e9telezhet\u0151 ugyanis, hogy \u00faj j\u00e1rv\u00e1nyok kialakul\u00e1s\u00e1hoz vezetn\u00e9nek.<\/p>\n\n\n\n

A K\u00ednai Tudom\u00e1nyos Akad\u00e9mia kutat\u00f3i \u00f6sszesen 21 gleccserb\u0151l vettek j\u00e9gmint\u00e1t a Tibeti-fenns\u00edkon. Ezut\u00e1n v\u00e9gezt\u00e9k el a mikrob\u00e1k genomj\u00e1nak elemz\u00e9s\u00e9t.<\/p>\n\n\n\n

A felfedezett mikroorganizmusok k\u00f6z\u00f6tt bakt\u00e9riumok, gomb\u00e1k \u00e9s alg\u00e1k is voltak. Enn\u00e9l azonban sokkal meglep\u0151bb, hogy a fajok mintegy 98 sz\u00e1zal\u00e9ka teljesen ismeretlen volt a tudom\u00e1ny sz\u00e1m\u00e1ra.<\/p>\n\n\n\n

A sz\u00e9ls\u0151s\u00e9ges k\u00f6rnyezeti felt\u00e9telek, p\u00e9ld\u00e1ul az alacsony h\u0151m\u00e9rs\u00e9klet, a napsug\u00e1rz\u00e1s, az id\u0151szakos fagy\u00e1si-olvad\u00e1si ciklusok \u00e9s a t\u00e1panyaghi\u00e1ny ellen\u00e9re a gleccserek felsz\u00edne v\u00e1ltozatos \u00e9letform\u00e1kat rejt \u2013 \u00f6sszegezt\u00e9k munk\u00e1jukat a kutat\u00f3k.<\/p>\n\n\n\n

A Live Science szerint 2020 janu\u00e1rj\u00e1ban egy m\u00e1sik kutat\u00f3csapat, amely egyetlen gleccserb\u0151l sz\u00e1rmaz\u00f3 j\u00e9gmint\u00e1kat elemzett, v\u00edrusok 33 k\u00fcl\u00f6nb\u00f6z\u0151 csoportj\u00e1t fedezte fel. Ezek k\u00f6z\u00fcl 28-at m\u00e9g soha nem l\u00e1ttak.<\/p>\n\n\n\n

A kutat\u00f3k azonban nem is a felfedezett v\u00edrusok miatt agg\u00f3dnak igaz\u00e1n, hanem a kl\u00edmav\u00e1ltoz\u00e1ssal j\u00e1r\u00f3 j\u00e9golvad\u00e1s miatt. Egy 2021 \u00e1prilis\u00e1ban megjelent tanulm\u00e1ny szerint 2000 \u00e9s 2019 k\u00f6z\u00f6tt a F\u00f6ld szinte minden gleccsere gyorsul\u00f3 \u00fctem\u0171 j\u00e9gvesztes\u00e9get mutatott. Ez pedig n\u00f6veli annak az es\u00e9ly\u00e9t, hogy a k\u00fcl\u00f6nf\u00e9le organizmusok kiszabadulnak a jeges b\u00f6rt\u00f6neikb\u0151l.<\/p>\n\n\n\n
