Ukufudumala kwembulunga yonke kunciphisa inani lezinyamazane

Reno

Isilwane esifanekisela amaholidi kaKhisimusi, inyamazane yezilwane, sinenkinga enzima ngenxa yokufudumala kwembulunga yonke ngokusho kocwaningo olwenziwe emhlanganweni waminyaka yonke we-British Ecological Society (BES) eLiverpool futhi olushicilelwe ephephabhukwini i-Global Change Biology. Inani labantu liyancipha, nalabo abazalwayo bahlala bencane futhi bancane.

Kungaba sengozini yokuqothulwa? Kungenzeka. Ake sibone ukuthi kungani.

I-reindeer eyazalelwa eNorway Arctic ngo-1994 yayinesisindo esingu-55kg, kodwa eyakwenza ngo-2010 yayinesisindo esingamaphesenti ayishumi nambili, okusho ukuthi, ama-48kg. I-12% ingahle ibonakale incane, kepha kufanele kubhekelwe lokho kwalesi silwane isisindo sibaluleke kakhulu ekukhiqizweni nasekusindeni kohloboNjengoba kushiwo uSteve Albon, umholi ocwaningweni, owengeze wathi: "Imibiko ikhombisile ukuthi lapho isisindo sabantu abadala singaphansi kuka-50kg, inani labantu lihle kakhulu."

Amazinga okushisa angaphezulu kwe-Arctic, ngokusho kososayensi, angama-2,8 degrees Celsius aphezulu kunango-2015, ngakho-ke i-reindeer inezinkinga eziningi ngokwengeziwe zokondla obulembu nobulembu njengoba lezi zingasakwazi ukufinyelelwa kubo njengoba zifakwe ngaphansi kongqimba lweqhwa ebusika. Iqhwa eliwela ezindaweni ezineqhwa elivimbela lezi zilwane ukuthi zingondli.

I-Reindeer

Indlala ingadala isisu, noma yenze ukuthi ingane izalwe isisindo esiphansi kakhulu kunokujwayelekile, kangangoba Ama-reindeer angama-61.000 abulawe yindlala e-Peninsula yaseYamal kuphela, eSiberia, ngesikhathi sasebusika sika-2013 kuya ku-2014 ngenxa yemvula enamandla eqhweni.

Leli thimba belilandela umkhondo wezinyamazane i-Arctic kusukela ngo-1994, liyithatha futhi liyikala lisukela ezinyangeni eziyishumi ubudala, indlela elalilandela njalo ebusika kanye naleyo elalilisebenzisa ukubuyisa unyaka olandelayo licabangela ubukhulu balo nesisindo salo.
