Me pak fjal\u00eb, ajo q\u00eb kemi qen\u00eb d\u00ebshmitare e dekadave t\u00eb fundit nuk \u00ebsht\u00eb asgj\u00eb e re: \u00ebsht\u00eb \u201cvet\u00ebm\u201d nj\u00eb p\u00ebrshpejtim shqet\u00ebsues i nj\u00eb dukurie m\u00eb t\u00eb vjet\u00ebr.<\/span><\/p>\n

Arinjt\u00eb polar\u00eb konsiderohen si nj\u00eb specie rojtare, gjendja sh\u00ebndet\u00ebsore e t\u00eb cil\u00ebve \u00ebsht\u00eb tregues i kushteve t\u00eb p\u00ebrgjithshme t\u00eb habitatit n\u00eb t\u00eb cilin jetojn\u00eb.<\/span><\/p>\n

P\u00ebr k\u00ebt\u00eb studim, ekipi nga Universiteti i Kopenhag\u00ebs mori n\u00eb konsiderat\u00eb n\u00eb ve\u00e7anti popullsin\u00eb q\u00eb jeton n\u00eb brigjet e Grenland\u00ebs, e cila p\u00ebrfshin nj\u00eb num\u00ebr ekzemplar\u00ebsh rreth 5000 nj\u00ebsi.<\/span><\/p>\n

Analiza integroi t\u00eb dh\u00ebna n\u00eb lidhje me kodin gjenetik t\u00eb arinjve, diet\u00ebn dhe shp\u00ebrndarjen e tyre, por edhe informacionin q\u00eb kemi p\u00ebr klim\u00ebn lokale: rezultati \u00ebsht\u00eb zbulimi se popullsia e Grenland\u00ebs ka ardhur duke u zvog\u00ebluar n\u00eb num\u00ebr.<\/span><\/p>\n

Arsyeja \u00ebsht\u00eb rritja e temperaturave t\u00eb detit, e cila b\u00ebn q\u00eb akulli t\u00eb t\u00ebrhiqet dhe p\u00ebr k\u00ebt\u00eb arsye arinjt\u00eb kan\u00eb m\u00eb pak ushqim n\u00eb dispozicion.<\/span><\/p>\n

Gjat\u00eb 20,000 viteve t\u00eb fundit, uj\u00ebrat e Grenland\u00ebs kan\u00eb par\u00eb temperaturat e tyre t\u00eb rriten me 0,2\/0,5 \u00b0C: duket pak, por ishte e mjaftueshme p\u00ebr t\u00eb shkaktuar nj\u00eb kolaps n\u00eb popullsin\u00eb e ariut polar prej 20 deri n\u00eb 40%.<\/span><\/p>\n

Problemi i v\u00ebrtet\u00eb \u00ebsht\u00eb se n\u00eb dekadat e ardhshme parashikimet e klim\u00ebs thon\u00eb se t\u00eb nj\u00ebjtat uj\u00ebra do t\u00eb ngrohen midis 2 dhe 5 \u00b0C, dometh\u00ebn\u00eb dhjet\u00eb her\u00eb m\u00eb shum\u00eb se sa ka ndodhur n\u00eb nj\u00ebzet mij\u00ebvje\u00e7ar\u00ebt e fundit.<\/span><\/p>\n

Kjo shpjegon pse gjendja e arinjve polar\u00eb konsiderohet kaq kritike: t\u00eb ndjesh\u00ebm ndaj rritjeve edhe minimale, ata do t\u00eb p\u00ebrballen me nj\u00eb ngrohje shum\u00eb t\u00eb shpejt\u00eb q\u00eb do t\u2019i privoj\u00eb nga akulli q\u00eb u nevojitet p\u00ebr t\u00eb jetuar dhe p\u00ebr t\u00eb marr\u00eb ushqim.<\/span><\/p>\n
