Kuba ubwoko bw'ibis bya Crested Ibis byongeye kugaruka mu Ntara ya Shaanxi, mu Bushinwa, bikwirakwira nyuma yo kurekurwa no kororoka neza.

Ubwoko (Inyoni):Ibis ya Crested (Nipponia nippon)

Ikinyamakuru:Emu

Incamake:

Gukwirakwiza inyamaswa zongeye kugaruka nyuma yo kurekurwa bivuga inzira yo kwigarurira amatungo no gutura mu buryo burambye. Kugira ngo habeho kandi hakomeze kubaho ubwoko bw’inyamaswa zongeye kugaruka, ingaruka z’ibintu bitandukanye ku gukwirakwiza inyamaswa zororewe mu buroko nyuma yo kurekurwa zigomba gusuzumwa. Muri iyi nkuru, twibanze ku moko abiri ya Crested Ibis (Nipponia nippon) yongeye kugaruka mu Ntara ya Shaanxi, mu Bushinwa. Twakoresheje uburyo bwinshi bwo gusuzuma ingaruka z’imyaka, ibiro by’umubiri, igitsina, igihe cyo kurekurwa, ingano y’aho kumenyera mu gihe cyo kongera kumenyera, n’igihe cyo kumenyera ku mubare w’abantu barekuwe. Ibisubizo byagaragaje ko ubushobozi bwo kurokoka bw’inyamaswa zongeye kugaruka bwari bufitanye isano ribi n’imyaka yazo mu Ntara ya Ningshan (Spearman, r = -0.344, p = 0.03, n = 41). Ibis byarekuwe mu Karere ka Ningshan na Qianyang byari bifite impuzandengo y’icyerekezo cyo gukwirakwira cya 210.53° ± 40.54° (ikizamini cya z cya Rayleigh: z = 7.881 > z0.05, p < 0.01, n = 13) na 27.05° ± 2.85° (ikizamini cya z cya Rayleigh: z = 5.985 > z0.05, p < 0.01, n = 6), uko bikurikirana, bigaragaza ko gukwirakwira kwakunze kwivanga mu cyerekezo kimwe muri ibyo bice byombi. Ibisubizo bya MaxEnt byagaragaje ko ikintu cy’ingenzi mu bidukikije gitera guhitamo aho kororerwa mu Karere ka Ningshan ari umurima w’imboga. Mu Karere ka Qianyang, imvura igira ingaruka ku guhitamo aho ibyari byahoze binyuze mu kugira ingaruka ku kuboneka kw'ibiribwa. Muri make, urwego rw'isuzuma rwakoreshejwe muri ubu bushakashatsi rushobora kuba urugero rwo guteza imbere ibikorwa by'ingenzi mu kubungabunga ibidukikije ku rwego rw'ubutaka kugira ngo inyamaswa zongere kugaruka.
