Historia filloi me zbulimin misterioz t\u00eb m\u00eb shum\u00eb se nj\u00ebqind breshkave, disa me guaska t\u00eb thyera, t\u00eb tjerat t\u00eb cop\u00ebtuara, t\u00eb gjitha t\u00eb ngordhura. P\u00ebrfundimi ishte nj\u00eb paralajm\u00ebrim i mundsh\u00ebm p\u00ebr t\u00eb ardhmen.<\/p>\n\n\n\n
Ishte Gregory Bult\u00e9, biolog nga Universiteti Carleton, ai q\u00eb i gjeti breshkat. N\u00eb prill 2022, ai ishte n\u00eb uj\u00ebrat e Liqenit Opinicon n\u00eb Ontarion lindor kur pa nj\u00eb breshk\u00eb t\u00eb ngordhur t\u00eb hart\u00ebs veriore e quajtur k\u00ebshtu sepse guaska e saj i ngjan vijave t\u00eb konturit t\u00eb nj\u00eb harte. Nd\u00ebrsa u p\u00ebrkul p\u00ebr ta marr\u00eb nga cek\u00ebt, ai pa nj\u00eb tjet\u00ebr.<\/p>\n\n\n\n
Bult\u00e9 vrapoi n\u00eb sht\u00ebpi, mori kostumin e notit dhe mask\u00ebn p\u00ebr thithje, dhe u fut n\u00eb ujin e akullt ku akulli i dimrit sapo ishte shkrir\u00eb p\u00ebr t\u00eb mbledhur trupat. Shpejt u b\u00eb e qart\u00eb se vdekjet ishin t\u00eb p\u00ebrhapura. Ai vazhdoi t\u00eb gjente grumbuj t\u00eb tjer\u00eb breshkash t\u00eb ngordhura dhe mbushi kova me to. \u201cThash\u00eb vetes, \u2018Uau, kur do t\u00eb mbaroj\u00eb kjo?’\u201d tha ai.<\/p>\n\n\n\n
N\u00eb fund, Bult\u00e9 kishte gati 150 breshka t\u00eb ngordhura, shum\u00eb prej t\u00eb cilave i njihte nga dy dekada monitorimi i liqenit pothuajse t\u00eb paprekur, t\u00eb rrethuar nga pyje. Ishte nj\u00eb goditje shkat\u00ebrruese, duke zhdukur rreth 10% t\u00eb popullat\u00ebs s\u00eb liqenit.<\/p>\n\n\n\n
Vdekjet ishin nj\u00eb mister p\u00ebr Bult\u00e9-n. Nga d\u00ebmtimet n\u00eb trupat e breshkave, dukej se shkaku ishte sulm grabitqar, dhe vet\u00ebm nj\u00eb kafsh\u00eb mund t\u00eb ishte mjaftuesh\u00ebm e fort\u00eb p\u00ebr k\u00ebt\u00eb, vidra e lumit.<\/p>\n\n\n\n
Por pyetja m\u00eb e madhe ishte pse kishte ndodhur kjo. Ishte hera e par\u00eb q\u00eb Bult\u00e9 shihte nj\u00eb vdekje masive n\u00eb liqen, dhe mbrojtja e breshkave n\u00eb t\u00eb ardhmen k\u00ebrkonte t\u00eb kuptuarit e shkakut t\u00eb k\u00ebsaj tragjedie.<\/p>\n\n\n\n
Breshkat e hart\u00ebs veriore jan\u00eb t\u00eb ve\u00e7anta. Ato jan\u00eb p\u00ebrshtatur p\u00ebr dimrat e ashp\u00ebr kanadez\u00eb duke kaluar muaj t\u00eb t\u00ebr\u00eb t\u00eb zhytura n\u00ebn uj\u00eb, n\u00ebn nj\u00eb shtres\u00eb t\u00eb trash\u00eb akulli, me metabolizmin shum\u00eb t\u00eb ngadalt\u00eb dhe temperatur\u00ebn e trupit af\u00ebr zeros.<\/p>\n\n\n\n
Femrat jan\u00eb rreth 10 her\u00eb m\u00eb t\u00eb r\u00ebnda se meshkujt, me nofulla t\u00eb forta p\u00ebr t\u00eb konsumuar molusqe, nd\u00ebrsa meshkujt ushqehen kryesisht me insekte dhe k\u00ebrmij. Megjithat\u00eb, madh\u00ebsia e femrave nuk i mbron gjithmon\u00eb; Bult\u00e9 ka dokumentuar se ato l\u00ebvizin n\u00eb uj\u00ebra m\u00eb t\u00eb thella dhe varrosin trupat e tyre n\u00eb sediment p\u00ebr t\u2019u shmangur nga meshkujt agresiv\u00eb gjat\u00eb sezonit t\u00eb \u00e7ift\u00ebzimit.<\/p>\n\n\n\n
N\u00eb Kanada, popullata e breshkave t\u00eb hart\u00ebs veriore num\u00ebron rreth 10,000 individ\u00eb dhe konsiderohet nj\u00eb specie \u201cshqet\u00ebsuese e ve\u00e7ant\u00eb\u201d p\u00ebr shkak t\u00eb k\u00ebrc\u00ebnimeve me t\u00eb cilat p\u00ebrballen. Ato varen nga liqenet dhe lumenjt\u00eb e m\u00ebdhenj, shpesh t\u00eb p\u00ebrdorur nga njer\u00ebzit, gj\u00eb q\u00eb i ekspozon ndaj aksidenteve me anije, shqet\u00ebsimeve gjat\u00eb ngrohjes dhe nd\u00ebrtimit t\u00eb foleve, si dhe rrjetave t\u00eb peshkimit.<\/p>\n\n\n\n
Breshkat jan\u00eb gjithashtu t\u00eb cenueshme p\u00ebr shkak t\u00eb jet\u00ebgjat\u00ebsis\u00eb s\u00eb tyre t\u00eb gjat\u00eb dhe shkall\u00ebs s\u00eb ul\u00ebt t\u00eb mbijetes\u00ebs s\u00eb t\u00eb vegj\u00eblve. Humbja e disa t\u00eb rriturve mund t\u00eb shkaktoj\u00eb r\u00ebnie t\u00eb konsiderueshme t\u00eb popullat\u00ebs. Historia e m\u00ebparshme tregon rreziqet: n\u00eb fund t\u00eb viteve 1980, vidrat vran\u00eb rreth 50% t\u00eb breshkave n\u00eb Parkun Algonquin, dhe m\u00eb shum\u00eb se dy dekada m\u00eb von\u00eb, popullata ende nuk ishte rikuperuar.<\/p>\n\n\n\n
P\u00ebr t\u00eb zbuluar se \u00e7far\u00eb ndodhi n\u00eb Liqenin Opinicon n\u00eb 2022, Bult\u00e9 p\u00ebrdori nj\u00eb proces eliminimi. Ai p\u00ebrjashtoi faktor\u00ebt njer\u00ebzor\u00eb dhe er\u00ebn, dhe arriti te ideja se ndryshimet n\u00eb temperatur\u00eb mund t\u00eb kishin lejuar vidrat t\u00eb dep\u00ebrtonin n\u00ebn akullin dim\u00ebror. N\u00ebse ky \u00ebsht\u00eb \u00e7el\u00ebsi i enigmes, pasojat mund t\u00eb jen\u00eb shqet\u00ebsuese: ndryshimet klimatike mund t\u2019i vendosin breshkat n\u00eb rrezik n\u00eb rritje.<\/p>\n\n\n\n
Bult\u00e9 theksoi se, pavar\u00ebsisht se nuk \u00ebsht\u00eb e qart\u00eb n\u00ebse klima ndikoi drejtp\u00ebrdrejt n\u00eb k\u00ebt\u00eb rast, m\u00ebnyra se si breshkat kalojn\u00eb dimrin t\u00eb grumbulluara n\u00eb t\u00eb nj\u00ebjtat vende \u00e7do vit i b\u00ebn ato t\u00eb prekshme. Sulmet e vidrave jan\u00eb nj\u00eb \u201ctregim paralajm\u00ebrues\u201d p\u00ebr r\u00ebnd\u00ebsin\u00eb e mbrojtjes s\u00eb vendeve ku breshkat kalojn\u00eb dimrin.<\/p>\n\n\n\n
Sot, breshkat p\u00ebrballen me k\u00ebrc\u00ebnime t\u00eb shumta: zhvillim bregdetar, prerje pem\u00ebsh, anije me helika, dhe sht\u00ebpi pran\u00eb liqeneve q\u00eb ndryshojn\u00eb akullin dhe mund t\u00eb lejojn\u00eb grabitqar\u00ebt t\u00eb hyjn\u00eb m\u00eb leht\u00eb. Ndryshimet klimatike shtojn\u00eb rrezikun p\u00ebr akull m\u00eb t\u00eb paq\u00ebndruesh\u00ebm dhe mund\u00ebsi m\u00eb t\u00eb m\u00ebdha p\u00ebr sulme.<\/p>\n\n\n\n
E ardhmja e breshkave t\u00eb hart\u00ebs veriore mbetet e pasigurt. Nj\u00eb k\u00ebrc\u00ebnim mund t\u00eb jet\u00eb i menaxhuesh\u00ebm, por ato p\u00ebrballen me kaq shum\u00eb sfida sa q\u00eb situata mund t\u00eb krahasohet me \u201cvdekje nga nj\u00eb mij\u00eb prerje,\u201d tha Bult\u00e9.\/<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"Historia filloi me zbulimin misterioz t\u00eb m\u00eb shum\u00eb se nj\u00ebqind breshkave, disa me guaska t\u00eb thyera, t\u00eb tjerat…\n","protected":false},"author":2,"featured_media":3203,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[148,153],"tags":[],"class_list":{"0":"post-3202","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-lajme","8":"category-magazina","9":"cs-entry","10":"cs-video-wrap"},"_links":{"self":[{"href":"https:\/\/sotpost.com\/index.php?rest_route=\/wp\/v2\/posts\/3202","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sotpost.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sotpost.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sotpost.com\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/sotpost.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=3202"}],"version-history":[{"count":1,"href":"https:\/\/sotpost.com\/index.php?rest_route=\/wp\/v2\/posts\/3202\/revisions"}],"predecessor-version":[{"id":3204,"href":"https:\/\/sotpost.com\/index.php?rest_route=\/wp\/v2\/posts\/3202\/revisions\/3204"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sotpost.com\/index.php?rest_route=\/wp\/v2\/media\/3203"}],"wp:attachment":[{"href":"https:\/\/sotpost.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3202"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sotpost.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3202"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sotpost.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3202"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
