Gukomatanya amakuru agezweho yo gukurikirana hamwe namateka yamateka atezimbere gusobanukirwa nubuturo bwimpeshyi bwiburasirazuba Ntoya Yera-Imbere ya Goose Anser erythropus.

Ubwoko (Avian):Ingagi Ntoya-Imbere Ingagi (Anser erythropus)

Ikinyamakuru:Ibidukikije n'Ubwihindurize

Ibisobanuro:

Ingagi Ntoya Yera-Imbere (Anser erythropus), ntoya mu ngagi za "imvi", yashyizwe ku rutonde nka Vulnerable kurutonde rutukura rwa IUCN kandi irinzwe muri leta zose. Hano hari abaturage batatu, hamwe n’abize cyane ni abaturage bo mu burasirazuba, basangiye Uburusiya n'Ubushinwa. Kuba kure cyane yubworozi bwororerwa bituma ahanini bidashoboka kubashakashatsi. Nkigisimburwa cyo gusurwa, gukurikirana kure inyoni ziva ahantu h'imbeho zituma ubushakashatsi bwigihe cyizuba. Mu gihe cyimyaka itatu, kandi bakoresheje ibikoresho bya GPS bikurikirana neza, abantu cumi n'umwe bo muri A. erythropus bakurikiranwe kuva ahantu h’imbeho y’Ubushinwa, kugeza mu mpeshyi, no kubika ahantu mu majyaruguru y’Uburusiya. Amakuru yakuwe muri uko gukurikirana, ashimangirwa nubushakashatsi bwakozwe ku butaka hamwe n’ubuvanganzo, yakoreshejwe mu kwerekana ikwirakwizwa ryizuba rya A. erythropus. Nubwo ubuvanganzo bwambere busobanura ibihe byimpeshyi, icyitegererezo cyerekana ko ahantu h’impeshyi hashobora kubaho, nubwo kwitegereza kugeza ubu bidashobora kwemeza A. erythropus ihari murwego rwicyitegererezo. Ahantu heza cyane haherereye ku nkombe z'inyanja ya Laptev, cyane cyane Delta ya Lena, mu kibaya cya Yana-Kolyma, no mu bibaya bito bya Chukotka hamwe n’imigezi migari yagutse hejuru y’inzuzi nini nka Lena, Indigirka, na Kolyma. Kuba bishoboka ko A. erythropus ihari bifitanye isano nubutumburuke buri munsi ya m 500 hamwe n’ibishanga byinshi, cyane cyane aho batuye ku nkombe, hamwe n’ikirere gifite imvura igwa mu gihembwe gishyushye kigera kuri mm 55 kandi bivuze ubushyuhe buri hagati ya 14 ° C muri Kamena-Kanama. Ihungabana ry’abantu naryo rigira ingaruka ku kibanza gikwiye, hamwe no kugabanuka buhoro buhoro ibinyabuzima bitangirira nko muri kilometero 160 uvuye aho abantu batuye. Gukurikirana kure amoko yinyamanswa birashobora guca icyuho cyubumenyi bukenewe kugirango ugereranye neza uburyo bwo gukwirakwiza amoko mu turere twa kure. Ubumenyi bwiza bwo gukwirakwiza amoko ni ngombwa mu gusobanukirwa n’ingaruka nini z’ibidukikije z’imihindagurikire y’isi ku isi no gushyiraho ingamba zo gucunga ibidukikije.
