Mitundu:Goose wamkulu wakutsogolo woyera ndi Goose wa Nyemba
Chidule:
Ku Nyanja ya Poyang, malo akulu kwambiri komanso amodzi mwamalo ofunikira kwambiri nyengo yozizira ku East Asia-Australasian Flyway, malo otchedwa Carex (Carex cinerascens Kük) meadows amapereka chakudya choyambirira cha atsekwe anyengo yozizira. Komabe, chifukwa cha kuchulukirachulukira kwa malamulo a mitsinje komanso zochitika zanyengo zowopsa monga chilala, umboni wowonera ukuwonetsa kuti kusamuka kwa atsekwe ndi Carex phenology sikungathe kusungidwa popanda kulowererapo kwa anthu, zomwe zimayika chiopsezo chachikulu chakusowa kwa chakudya m'nyengo yozizira. Chifukwa chake, kufunikira kwa kasungidwe kameneka patsamba la Ramsar kumasinthidwa kukhala kuwongolera dambo kuti zitsimikizire kuti chakudya chili chabwino. Kumvetsetsa zakudya zomwe atsekwe akakhala m'nyengo yachisanu ndi chinsinsi chothandizira kusamalira bwino dambo. Monga gawo la kukula ndi kuchuluka kwa michere yazakudya ndizomwe zimapangitsa kusankha kwazakudya za herbivore, mu kafukufukuyu, tidayesa zakudya zomwe timakonda potsata njira zopezera zakudya za Goose wa Greater White-fronted Goose (n = 84) ndi Bean Goose (n = 34) kuwerengera "zenera lodyera" malinga ndi kuchuluka kwa mbewu, kutalika ndi mphamvu. Kupitilira apo, tidakhazikitsa ubale pakati pamitundu itatu pamwambapa ya Carex kutengera muyeso wa in-situ. Zotsatira zake zikuwonetsa kuti atsekwe amakonda zomera zotalika kuyambira 2.4 mpaka 25.0 cm, zokhala ndi mapuloteni kuchokera pa 13.9 mpaka 25.2 %, komanso mphamvu zoyambira 1440.0 mpaka 1813.6 KJ/100 g. Ngakhale kuti mphamvu za zomera zimawonjezeka ndi msinkhu, ubale wa msinkhu wa mapuloteni ndi woipa. Mapindikidwe amtundu wosiyanawo ndi omwe akuwonetsa zovuta zoteteza kuti asamalire bwino pakati pa kuchuluka ndi zofunikira za atsekwe omwe ali m'nyengo yozizira. Kasamalidwe ka Carex meadow, monga kutchera, kuyenera kuyang'ana kwambiri pakuwongolera nthawi yochitapo kanthu kuti awonjezere kuchuluka kwa mphamvu ndikukhalabe ndi mapuloteni oyenera kuti mbalame zizikhala zolimba, kuberekana komanso kukhala ndi moyo kwa nthawi yayitali.
