Mokslininkai Arkties j\u016bros dugne u\u017efiksavo vaizd\u0105, kuris i\u0161 prad\u017ei\u0173 primin\u0117 savoti\u0161k\u0105 povandenin\u012f kap\u0105. Ta\u010diau v\u0117lesn\u0117 analiz\u0117 parod\u0117, kad tai grei\u010diausiai yra banginio kritimas \u012f dugn\u0105, tap\u0119s i\u0161tisa gyvyb\u0117s sala itin skurd\u017eioje aplinkoje.<\/p>\n

Atradimas padarytas ne nar\u0173, o nuotoliniu b\u016bdu valdoma povandenine transporto priemone \u201e\u00c6gir6000\u201c, kuri tyrim\u0173 metu perdav\u0117 detalius dugno vaizdus. \u012e akis krito ne\u012fprastai tankus vamzdeli\u0173 ir organizm\u0173 telkinys, ry\u0161kiai i\u0161siskiriantis i\u0161 aplinkini\u0173 nuogul\u0173.<\/p>\n

Kas i\u0161dav\u0117 tikr\u0105j\u0105 radinio prigimt\u012f<\/h2>\n

Gr\u012f\u017eus \u012f t\u0105 pa\u010di\u0105 viet\u0105 ir pa\u0117mus m\u0117ginius, aplink \u012frang\u0105 pakilo tamsi, beveik juoda nuos\u0117d\u0173 \u201edebes\u0173\u201c u\u017euolaida. Toks vaizdas paprastai rodo didel\u012f organin\u0117s med\u017eiagos kiek\u012f ir ma\u017e\u0105 deguonies koncentracij\u0105 gilesniuose sluoksniuose, kur vyksta intensyvus irimas.<\/p>\n

Perko\u0161us m\u0117ginius laive paai\u0161k\u0117jo, kad dugne slypi kaulai ir dantys, taip pat fragmentai, galintys priklausyti banginio klausos strukt\u016broms. Pirminiai duomenys leid\u017eia \u012ftarti, kad tai dantytasis banginis, ta\u010diau tiksli r\u016b\u0161is bus nustatyta tik atlikus papildomus tyrimus.<\/p>\n

Banginio k\u016bnas dugne kuria gyvyb\u0117s oaz\u0119<\/h2>\n

Kartu su kaulais aptikta gausi bestuburi\u0173 bendrija: daugia\u0161er\u0117s kirm\u0117l\u0117s, dvigeld\u017eiai moliuskai, sraig\u0117s ir stamb\u016bs izopodai. Dalis \u0161i\u0173 organizm\u0173 minta tiesiogiai irimo produktais, o kiti klesti d\u0117l chemini\u0173 jungini\u0173, i\u0161siskirian\u010di\u0173 skylant riebalams ir kaulams.<\/p>\n

Tokie banginio kritimai \u012f dugn\u0105 yra reti, bet ekologi\u0161kai labai svarb\u016bs rei\u0161kiniai giliavanden\u0117se ekosistemose. Kai \u012f dugn\u0105 nusileid\u017eia didelis k\u016bnas, jis i\u0161 prad\u017ei\u0173 tampa maistu mait\u0117doms, v\u0117liau irimo procesus palaikan\u010dioms bakterijoms, o galiausiai ilg\u0105 laik\u0105 i\u0161laiko specializuotas bendrijas, kurios gali gyvuoti metus ar net de\u0161imtme\u010dius.<\/p>\n

Kod\u0117l tai svarbu ne tik mokslui<\/h2>\n

Tyr\u0117jai atkreipia d\u0117mes\u012f, kad tokios trapios dugno \u201eoaz\u0117s\u201c gali b\u016bti lengvai pa\u017eeistos \u017emogaus veiklos. Ypa\u010d did\u0117jant susidom\u0117jimui j\u016bros dugno i\u0161tekli\u0173 paie\u0161ka ir gavyba, svarbu suprasti, kur formuojasi jautr\u016bs biotopai ir kaip jie atsistato po sutrikdymo.<\/p>\n

\u0160is atvejis primena, kad net ir tamsiausiose, \u0161altose Arkties gelm\u0117se mirtis gali virsti gyvyb\u0117s sprogimu. Vienas banginio k\u016bnas tampa maisto ir buveini\u0173 grandin\u0117s prad\u017eia ten, kur \u012fprastai biologini\u0173 i\u0161tekli\u0173 b\u016bna labai ma\u017eai.<\/p>\n","protected":false},"excerpt":{"rendered":"
