Pfupiso:

Nzvimbo dzakakura dzemvura dzenguva pfupi dziri paLake Poyang, dzakagadzirwa nekuchinja kukuru kwemwaka wemvura, dzinoumba nzvimbo huru yechando yeAnatidae dzinotama muChina. Kuderera kwenzvimbo dzine mvura mumakore gumi nemashanu apfuura kwakaita kuti pave nezvirongwa zvekuvaka Dam rePoyang kuti mvura irambe yakawanda muchando ichichengetwa. Kuchinja kwemamiriro emvura echisikigo kuchakanganisa shiri dzemumvura dzinoenderana nekuchinja kwemvura kuti chikafu chiwanikwe uye chiwanikwe. Takatevera mhando mbiri dzemagoose dzine maitiro akasiyana ekudya (magoose makuru ane fronted white geese Anser albifrons [mafura] uye magoose eswan geese Anser cygnoides [magoose-feeding species]) munguva yechando mbiri dzine mvura yakasiyana (kuderera kuri kuramba kuchiitika muna 2015; mvura yakaramba yakakwira muna 2016, yakafanana neyakafanotaurwa mushure meDam rePoyang), tichiongorora mhedzisiro yekuchinja kwemvura pakusarudzwa kwenzvimbo dzadzo dzekugara zvichibva pamiti nekukwira kwayo. Muna 2015, mageese ane fronted machena akashandisa zvakanyanya kugadzira madhaka akatevedzana, achidya ma graminoid swards mapfupi ane hutano, ukuwo ma swan geese achichera substrates pamucheto wemvura kuti awane ma tubers. Iyi ecotone yakakosha inoburitsa pachena chikafu chiri pasi pemvura uye inotsigira kukura kwema graminoid pakutanga panguva yekuderera kwemvura. Munguva yemvura yakakwira muna 2016, mhando dzese dzakasarudza madhaka akapararira, asiwo kune nzvimbo dzakawanda dzekugara dzine ma graminoid swards emwaka wakareba nekuti kuwana ma tubers nekukura kwe graminoid itsva kwakaganhurirwa mumamiriro emvura yakawanda. Ma graminoid swards akareba anopa chikafu chisina simba kune mhando dzese dziri mbiri. Kuderedzwa kukuru kwenzvimbo yakakodzera uye kuvharirwa kune zvekudya zvisina pundutso nehuwandu hwemvura yakawanda zvinogona kuderedza kugona kwemageese kuunganidza mafuta akakwana kuti afambe, zvichikonzera mhedzisiro yekuenderera mberi kwehupenyu nekubereka. Zvakabuda muongororo yedu zvinoratidza kuti huwandu hwemvura muLake Poyang hunofanira kuramba huripo munguva yezhizha, asi huchibvumidzwa kudzikira zvishoma nezvishoma, zvichiratidza nzvimbo itsva munguva yechando kuti shiri dzemumvura dzinobva kumapoka ese emhuka dzinodya dzikwanise kupinda.
