\u00cen \u00eentuneric total \u0219i \u00eentr-o atmosfer\u0103 greu de suportat pentru oameni, via\u021ba a g\u0103sit o solu\u021bie neobi\u0219nuit\u0103: energia nu vine de la Soare, ci din reac\u021bii chimice, noteaz\u0103 portalul francez Esp\u00e8ces-menac\u00e9es<\/a><\/p>\n

O lume izolat\u0103 sub litoralul rom\u00e2nesc<\/h2>\n

Descoperit\u0103 la sf\u00e2r\u0219itul anilor \u201980 \u00een apropiere de Mangalia, Pe\u0219tera Movile a r\u0103mas separat\u0103 de mediul exterior timp de peste cinci milioane de ani. Straturile de argil\u0103 \u0219i calcar au func\u021bionat ca o barier\u0103 natural\u0103, permi\u021b\u00e2nd dezvoltarea unui ecosistem cu caracteristici excep\u021bionale.<\/p>\n

Izolarea \u00eendelungat\u0103 a favorizat apari\u021bia unor specii endemice, adaptate unor condi\u021bii care ar fi ostile pentru majoritatea organismelor de la suprafa\u021b\u0103. Tocmai fragilitatea acestui univers face ca accesul oamenilor s\u0103 fie sever restric\u021bionat.<\/p>\n

Via\u021ba care nu are nevoie de lumina Soarelui<\/h2>\n

Una dintre particularit\u0103\u021bile majore ale pe\u0219terii este modul \u00een care func\u021bioneaz\u0103 lan\u021bul trofic. \u00cen ecosistemele obi\u0219nuite, lumina solar\u0103 \u0219i fotosinteza stau la baza producerii materiei organice. \u00cen subteranul de l\u00e2ng\u0103 Mangalia, rolul principal revine \u00eens\u0103 bacteriilor chemoautotrofe.<\/p>\n

Aceste microorganisme utilizeaz\u0103 energia ob\u021binut\u0103 prin oxidarea sulfului \u0219i a altor compu\u0219i chimici. Bacteriile formeaz\u0103 pelicule care devin hran\u0103 pentru nevertebrate, acestea fiind, la r\u00e2ndul lor, consumate de organisme mai mari.<\/p>\n

Practic, \u00eentregul ecosistem poate func\u021biona \u00een absen\u021ba luminii solare.<\/p>\n

Creaturi adaptate \u00eentunericului total<\/h2>\n

Milioanele de ani petrecute \u00een asemenea condi\u021bii \u0219i-au pus amprenta \u0219i asupra faunei. Unele vie\u021buitoare au ochii atrofia\u021bi, sunt depigmentate sau aproape translucide, iar altele au dezvoltat antene mai lungi, utile pentru orientarea \u00een \u00eentuneric.<\/p>\n

Printre organismele \u00eent\u00e2lnite se num\u0103r\u0103 izopode, miriapode, p\u0103ianjeni, lipitori \u0219i colembole. Unele au un metabolism lent, o adaptare important\u0103 \u00eentr-un mediu \u00een care resursele sunt limitate.<\/p>\n

Nici atmosfera nu seam\u0103n\u0103 cu cea de la suprafa\u021b\u0103. Aerul este foarte umed, s\u0103rac \u00een oxigen \u0219i bogat \u00een dioxid de carbon, iar prezen\u021ba hidrogenului sulfurat \u00eel face periculos pentru oameni.<\/p>\n

De la Mangalia la c\u0103utarea vie\u021bii extraterestre<\/h2>\n

Importan\u021ba Pe\u0219terii Movile dep\u0103\u0219e\u0219te biodiversitatea Rom\u00e2niei. Ecosistemul le ofer\u0103 oamenilor de \u0219tiin\u021b\u0103 un model pentru studierea modului \u00een care via\u021ba poate supravie\u021bui f\u0103r\u0103 lumin\u0103, dar \u0219i pentru \u00een\u021belegerea evolu\u021biei speciilor \u00een condi\u021bii de izolare extrem\u0103.<\/p>\n

Astfel de mecanisme prezint\u0103 interes inclusiv pentru astrobiologie: dac\u0103 organismele pot forma ecosisteme bazate pe energie chimic\u0103 \u00een subteranul Terrei, cercet\u0103torii pot lua \u00een calcul existen\u021ba unor procese asem\u0103n\u0103toare \u00een medii f\u0103r\u0103 lumin\u0103 de pe alte corpuri cere\u0219ti.<\/p>\n

Tocmai valoarea sa \u0219tiin\u021bific\u0103 impune protejarea strict\u0103 a pe\u0219terii. Introducerea accidental\u0103 a unor microorganisme din exterior sau modificarea condi\u021biilor de temperatur\u0103 \u0219i ap\u0103 ar putea afecta un echilibru biologic construit \u00een milioane de ani.<\/p>\n","protected":false},"excerpt":{"rendered":"
