Ubwoko (Inyoni):Whimbrels (Numenius phaeopus)

Incamake:

Ahantu ho guhagarara ni ingenzi cyane mu kongeramo lisansi no kuruhuka inyoni zimuka. Gusobanura ibisabwa ku hantu inyoni zimuka zihagarara ni ingenzi mu gusobanukirwa ibidukikije byo kwimuka no kubungabunga ibidukikije. Ariko, aho inyoni zimuka zihagarara ntihigwaga neza, kandi itandukaniro ry’aho ziba mu moko menshi ntabwo ryarasuzumwe. Twakurikiranye uburyo inyoni zimuka zimuka zigenda, Numenius phaeopus, dukoresheje uburyo Global Positioning System – Global System for Mobile Communication tags kuri Chongming Dongtan, ahantu hakomeye ho guhagarara mu Nyanja y’Umuhondo y’Amajyepfo, mu Bushinwa, mu mpeshyi ya 2016 no mu mpeshyi no mu gihe cy’impeshyi ya 2017. Uburyo bwo gusubira inyuma mu buryo bw’ikoranabuhanga n’ingero nyinshi byakoreshejwe mu kumenya ingaruka z’inyoni imwe, diel factor (ku manywa ugereranyije n’ijoro), n’uburebure bw’amazi ku ikoreshwa ry’ahantu Whimbrels ihagarara mu gihe cyo guhagarara. Uburemere bw’ibikorwa bya Whimbrels bwari buke mu ijoro ugereranyije n’igihe cy’amanywa, mu gihe intera ntarengwa yagaragazaga ko Whimbrels yimukaga yari ndende hagati y’amanywa n’ijoro. Ibisigazwa by’amazi n’ibisigazwa byakoreshejwe cyane n’ibinyabuzima byose mu bihe bitatu: > 50% na 20% by’inyandiko zose zavuye muri ibisigazwa by’amazi n’ibisigazwa by’amazi. Imikoreshereze y’aho batuye itandukanye cyane hagati y’ibinyabuzima; ubutaka bw’ubuhinzi n’ubutaka bw’amashyamba byakoreshejwe na bamwe mu bisigazwa mu mpeshyi ya 2016, mu gihe igishanga cyo gusana hafi y’agace k’inyanja cyakoreshejwe na bamwe mu bantu mu 2017. Muri rusange, ibisigazwa by’amazi, ubutaka bw’ubuhinzi n’amashyamba byakoreshejwe cyane ku manywa, mu gihe ibisigazwa by’amazi byakoreshwaga cyane nijoro. Uko uburebure bw’amazi y’inyanja bwagendaga bwiyongera, ikoreshwa ry’ibisigazwa ry’amazi ryaragabanutse mu gihe ikoreshwa ry’ibisigazwa ry’amazi ryiyongeraga. Ibisubizo bigaragaza ko gukurikirana ibintu bishingiye ku giti cyabyo bishobora gutanga amakuru arambuye ku ikoreshwa ry’aho batuye haba ku manywa no nijoro. Itandukaniro mu ikoreshwa ry’aho batuye hagati y’ibinyabuzima n’ibihe bigaragaza akamaro k’ahantu hatandukanye ho kubungabunga inyoni.
