Bisaba abantu babiri kugera kuri Tango: Uburebure bw'ibimera n'ingano y'intungamubiri bigena uburyo bwo guhitamo indyo y'ibishyimbo biri mu gihe cy'itumba mu kiyaga cya Poyang, igishanga cya Ramsar.

Incamake:

Mu kiyaga cya Poyang, ahantu hanini kandi hakomeye cyane ho guterera mu gihe cy'itumba mu burasirazuba bwa Aziya-Ositaraliya, ubwatsi bwa Carex (Carex cinerascens Kük) butanga isoko y'ibanze y'ibiribwa by'inkende zo mu gihe cy'itumba. Ariko, bitewe n'amabwiriza akomeye y'imigezi n'ibihe bikomeye by'ikirere nk'amapfa, ibimenyetso byagaragaye bigaragaza ko guhuza kw'imuka ry'inkende n'imiterere ya Carex bitashoboraga gukomeza hatabayeho ubufasha bw'abantu, bigatera ibyago bikomeye byo kubura ibiribwa mu gihe cy'itumba. Kubera iyo mpamvu, ubwishingizi bw'ibanze muri iki kibanza cya Ramsar bwimuriwe ku kunoza ubwatsi butose kugira ngo harebwe ko ibiribwa ari byiza. Gusobanukirwa ibyo inkende zo mu gihe cy'itumba zikunda ni ingenzi mu gucunga neza ubwatsi butose. Kubera ko intambwe yo gukura n'urwego rw'intungamubiri by'ibimera ari byo bintu by'ingenzi bigira ingaruka ku ihitamo ry'ibiribwa by'inyamaswa zirya ibyatsi, muri ubu bushakashatsi, twasuzumye ibiryo bikunzwe cyane dukurikirana inzira zo gushakisha za Greater White-fronted Goose (n = 84) na Bean Goose (n = 34) kugira ngo dupime "idirishya ryo gushakisha" mu bijyanye n'uburebure bw'ibimera, urwego rwa poroteyine, n'ingano y'ingufu. Byongeye kandi, twashyizeho isano iri hagati y'ibintu bitatu byavuzwe haruguru bya Carex dushingiye ku bipimo biri mu gace. Ibisubizo bigaragaza ko inkende zikunda ibimera bifite uburebure buri hagati ya cm 2.4 na 25.0, hamwe n'ingano ya poroteyine kuva kuri 13.9 kugeza 25.2%, hamwe n'ingano y'ingufu kuva kuri 1440.0 kugeza 1813.6 KJ/100 g. Nubwo ingufu z'ibimera ziyongera uko uburebure bugenda, isano iri hagati y'uburebure na poroteyine ni mbi. Imiterere itandukanye y'ikura igaragaza imbogamizi yo kubungabunga ibidukikije kugira ngo hakomeze kubaho uburinganire hagati y'ingano n'ubuziranenge bw'ibikenewe mu gihe cy'itumba. Gucunga ubwatsi bwa Carex, nko guca urutoki, bigomba kwibanda ku kunoza igihe cyo gukora kugira ngo haboneke ingufu nyinshi mu gihe hagumana ingano ikwiye ya poroteyine kugira ngo inyoni zigire ubuzima bwiza, zororoke kandi zikomeze kubaho igihe kirekire.
