Abstract
Nepo masango emusango ari muchando muNorth America neEurope ari kunyanya kubudirira nekushandisa minda yekurima, ayo ari kuChina (anoita seanongogara munzvimbo dzemvura) anowanzo kuderera. Zvishandiso zveTelemetry zvakanamirwa kune makumi matanhatu nenomwe emusango emuchando emarudzi mashanu akasiyana munzvimbo nhatu dzakakosha dzemvura muYangtze River Floodplain (YRF), China kuona kushandiswa kwepekugara. 50 vanhu vemarudzi matatu ari kuderera vanga vakangoita diurnally vakaganhurirwa kumatoro echisikigo; 17 vanhu kubva kumarudzi maviri anoratidza kugadzikana maitiro vakashandisa manyoro 83% uye 90% yenguva, neimwe nzira vachitendeukira kumapurazi. Mhedzisiro iyi inosimbisa zvidzidzo zvekare zvakabatanidza kuderera pakati peChinese yechando geese nekurasikirwa kwenzvimbo yakasikwa uye kuparara kunokanganisa kuwanikwa kwechikafu. Mhedzisiro iyi inobatsirawo pakutsanangura kushata kwekuchengetedza kweChinese wintering geese kana zvichienzaniswa nemhando imwe chete nedzimwe mhuka dzehanzi dzinogara munguva yechando dziri pedyo neKorea neJapan, kumadokero kweEurope neNorth America, idzo dzinodya dzinenge dzakazara munzvimbo dzekurima, dzichivasunungura kubva mukuganhurwa kwehuwandu hwechando.
