Ikinyamakuru:Imyitwarire yinyamaswa Umubumbe wa 215, Nzeri 2024, Urupapuro 143-152
Ubwoko (bat):crane-ijosi
Ibisobanuro:
Guhuza abimukira bisobanura urwego abimukira bavanze mumwanya nigihe. Bitandukanye n'abantu bakuru, inyoni zo mu bwoko bwa subadult zikunze kwerekana uburyo bwo kwimuka kandi zigakomeza kunonosora imyitwarire yimuka n’aho zigenda zikura. Kubwibyo, ingaruka zimikorere ya subadult kumurongo rusange wimuka ushobora kuba utandukanye nabakuze. Nyamara, ubushakashatsi buriho kubijyanye no guhuza abimukira akenshi birengagiza imiterere yimyaka yabaturage, ahanini byibanda kubantu bakuru. Muri ubu bushakashatsi, twakoze ubushakashatsi ku ruhare rw’imigendekere y’ibinyabuzima mu guhuza urwego rw’abaturage dukoresheje imibare ikurikirana ibyogajuru biva mu ndege 214 zifite ijosi ryirabura, Grus nigricollis, mu burengerazuba bw’Ubushinwa. Twabanje gusuzuma itandukaniro mugutandukanya umwanya mubice bitandukanye byimyaka dukoresheje coefficient ya Mantel ihoraho yigihe gito hamwe namakuru yatanzwe nabana bato 17 bakurikiranwe mumwaka umwe mumyaka 3 ikurikiranye. Twahise tubara guhuza kwimuka kwigihe gito kubaturage bose (bigizwe nibyiciro bitandukanye) kuva 15 Nzeri kugeza 15 Ugushyingo tugereranya ibisubizo nibyavuye mumuryango (bigizwe nabana bato nabakuze gusa). Ibisubizo byacu byagaragaje isano iri hagati yo gutandukana kwigihe gito mugutandukana kwimyaka hamwe nimyaka nyuma yabana bato batandukanijwe nabakuze, byerekana ko subadult ishobora kuba yarahinduye neza inzira zabo zo kwimuka. Byongeye kandi, guhuza kwimuka kwimyaka yose ya cohort byari biciriritse (munsi ya 0,6) mugihe cyitumba, kandi cyane cyane munsi yitsinda ryumuryango mugihe cyizuba. Dufatiye ku ngaruka nini ziterwa no kwimuka kwimuka, turasaba gukoresha amakuru yakusanyirijwe mu nyoni mu byiciro byose kugirango tunonosore neza igipimo cy’imibare ihuza abimukira.
