Ubwoko (Avian):Ingagi nini yera-Imbere (Anser albifrons)

Ibisobanuro:

Igitekerezo cy’abimukira cyerekana, kandi ubushakashatsi bumwe na bumwe bwerekana ko, kugira ngo duhatanire ahantu heza ho kororera no kongera intsinzi y’imyororokere, abimukira mu ndege ndende bakunze gufata ingamba zo kugabanya igihe mu gihe cyo kwimuka kw’impeshyi, bikaviramo kwimuka igihe gito ugereranije n’izuba. Twifashishije imiyoboro ya GPS / GSM, twakurikiranye iyimuka ryuzuye ry’inyamanswa nini 11 zera zera zera (Anser albifrons) hagati y’amajyepfo y’Ubushinwa n’Uburusiya bw’Uburusiya, kugira ngo tumenye igihe cyo kwimuka n’inzira z’abatuye Aziya y’iburasirazuba, kandi tugereranya itandukaniro riri hagati yigihe cyo kwimuka kwizuba n’izuba. Twabonye ko kwimuka mu mpeshyi (iminsi 79 ± 12) byatwaye inshuro zirenga ebyiri kugirango zipime intera imwe nko mu gihe cyizuba (iminsi 35 ± 7). Iri tandukaniro mugihe cyo kwimuka ryagenwe ahanini nigihe kinini cyakoreshejwe mugihe cyizuba (iminsi 59 ± 16) ugereranije no mumuhindo (iminsi 23 ± 6) kurubuga rwinshi. Turasaba ko izo ngagi, zifatwa nk'aborozi bashoramari igice, zakoresheje hafi bitatu bya kane byigihe cyo kwimuka ahantu hose zihagarara kugirango zibone ububiko bwingufu zishoramari ryanyuma mubyororokere, nubwo tudashobora kwanga hypothesis ivuga ko igihe cyizuba cyimpeshyi nacyo cyagize uruhare mugihe cyo guhagarara. Mu gihe cy'izuba, babonye amaduka akenewe ku mbuto zororoka bihagije kugira ngo bagere mu majyaruguru y'uburasirazuba bw'Ubushinwa ahacururizwa hafi nta guhagarara, ibyo bikaba byaragabanije igihe cyo guhagarara mu gihe cy'izuba bigatuma abantu bimuka mu gihe cyizuba kurusha impeshyi.
