Aho zishobora kuba n'uko zibungabunga Swan Geese (Anser cygnoides) ku muhanda wa East Asian Flyway.

Ubwoko (Inyoni):Inkende zo mu bwoko bwa Swan geese (Anser cygnoides)

Ikinyamakuru:Gutahura kure

Aho inyoni zimuka zituye hatanga umwanya w'ingenzi kugira ngo zikomeze kubaho no kororoka. Kumenya aho zishobora kuba mu byiciro by'ingendo ngarukamwaka n'ingaruka zabyo ni ingenzi mu kubungabunga inzira y'indege. Muri ubu bushakashatsi, twabonye uburyo bwo gukurikirana inyoni umunani zo mu bwoko bwa swan geese (Anser cygnoides) zikora mu gihe cy'itumba mu kiyaga cya Poyang (28°57′4.2″, 116°21′53.36″) kuva mu 2019 kugeza 2020. Dukoresheje uburyo bwa Maximum Entropy species distribution mode, twasuzumye uburyo inyoni zo mu bwoko bwa swan geese zikora mu gihe cy'ingendo zazo. Twasesenguye uruhare rw'ibintu bitandukanye bidukikije mu bijyanye no kuba ahantu hakwiriye inyoni zo mu bwoko bwa swan geese no kubungabunga inyoni zo mu bwoko bwa swan geese. Ibisubizo byacu bigaragaza ko ahantu ha mbere inyoni zo mu bwoko bwa swan geese zikora mu gihe cy'itumba ziri mu nkengero zo hagati n'izo hasi z'uruzi rwa Yangtze. Ahantu hahagaze hakwirakwiriye cyane, cyane cyane mu nkengero za Bohai, mu nkengero zo hagati z'uruzi rw'umuhondo, no mu kibaya cy'amajyaruguru y'uburasirazuba, kandi byagutse mu burengerazuba kugeza muri Mongoliya y'imbere na Mongoliya. Ahantu ho kororera higanje muri Mongoliya y'imbere no mu burasirazuba bwa Mongoliya, mu gihe hari n'ahandi hatandukanye mu burengerazuba bwa Mongoliya. Ingaruka z'ibintu by'ingenzi bifitanye isano n'ibidukikije ziratandukanye mu hantu ho kororera, aho bahagarara, no mu gihe cy'itumba. Ahantu ho kororera hagizweho ingaruka n'ubuhaname, uburebure, n'ubushyuhe. Ubuhaname, igipimo cy'aho abantu bakandagira, n'ubushyuhe nibyo bintu by'ingenzi byagize ingaruka ku hantu bahagarara. Ahantu ho kororera hagenwe n'imikoreshereze y'ubutaka, uburebure, n'imvura. Imiterere y'aho hantu hororera ni 9.6% ku hantu ho kororera, 9.2% ku hantu ho kororera, na 5.3% ku hantu bahagarara. Bityo, ibyo twabonye bitanga isuzuma mpuzamahanga ryimbitse ry'aho hantu hashobora kurengera ubwoko bw'inkende ku muhanda wa East Aziya.
