Iintlobo:iGreater White-fronted Goose kunye neBean Goose
Isishwankathelo:
KwiLake Poyang, eyona ndawo inkulu neyona ibalulekileyo yokuchitha ixesha lasebusika kwi-East Asian-Australasian Flyway, amadlelo eCarex (Carex cinerascens Kük) anika umthombo oyintloko wokutya kwamahansi asebusika. Nangona kunjalo, ngenxa yokulawulwa komlambo okuqinisiweyo kunye neziganeko zemozulu ezingaqhelekanga ezifana nembalela, ubungqina bokuqaphela bubonisa ukuba ukuhambelana kokufuduka kwamahansi kunye ne-phenology yeCarex akunakugcinwa ngaphandle kokungenelela kwabantu, nto leyo ebeka umngcipheko omkhulu wokunqongophala kokutya ngexesha lasebusika. Ngenxa yoko, eyona nto iphambili kulondolozo kule ndawo yaseRamsar itshintshelwe ekuphuculweni kwamadlelo amanzi ukuqinisekisa umgangatho wokutya ofanelekileyo. Ukuqonda ukutya okukhethwayo kwamahansi asebusika ngundoqo wolawulo olusebenzayo lwamadlelo amanzi. Njengoko inqanaba lokukhula kunye nenqanaba lezondlo zezityalo zokutya zizinto ezibalulekileyo ezichaphazela ukukhethwa kokutya kwezilwanyana ezitya utyani, kolu phononongo, sithathe iisampulu zokutya ezikhethwayo ngokulandela iindlela zokufuna ukutya zeGreater White-fronted Goose (n = 84) kunye neBean Goose (n = 34) ukuze silinganise "ifestile yokutya" ngokwemilinganiselo yobude bezityalo, inqanaba leproteni, kunye nomxholo wamandla. Ngaphezu koko, siseke ubudlelwane phakathi kwezinto ezintathu ezichazwe apha ngasentla zeCarex ngokusekelwe kwimilinganiselo yangaphakathi. Iziphumo zibonisa ukuba iihansi zithanda izityalo ezinobude obuqala kwi-2.4 ukuya kwi-25.0 cm, kunye nomxholo weproteni ukusuka kwi-13.9 ukuya kwi-25.2 %, kunye nomxholo wamandla ukusuka kwi-1440.0 ukuya kwi-1813.6 KJ/100 g. Ngelixa umxholo wamandla ezityalo unyuka ngokuphakama, ubudlelwane benqanaba lokuphakama kunye neproteni abulunganga. Iigrafu zokukhula ezichaseneyo zibonisa umngeni wolondolozo ukugcina ibhalansi ebuthathaka phakathi kweemfuno zobungakanani kunye nomgangatho weehansi zasebusika. Ulawulo lwengca yeCarex, njengokucheba ukhula, kufuneka lugxile ekuphuculeni ixesha lokusebenza ukuze kwandiswe umbane ngelixa kugcinwa inqanaba elifanelekileyo leproteni ukuze iintaka zihlale ziphilile ixesha elide, zizale kwaye ziphile ixesha elide.
