Ngakhale kuti zitsekwe zakutchire zomwe zimakhala nyengo yozizira ku North America ndi ku Europe zikukula kwambiri pogwiritsa ntchito minda, zomwe zili ku China (zomwe zimawoneka ngati madambo achilengedwe) zikuchepa. Zipangizo zama telemetry zidalumikizidwa ndi atsekwe akuthengo 67 am'nyengo yozizira amitundu isanu yosiyanasiyana m'madambo atatu ofunikira ku Yangtze River Floodplain (YRF), China kuti adziwe momwe angagwiritsire ntchito malo. Anthu 50 a mitundu itatu yomwe ikucheperachepera pafupifupi tsiku lililonse amakhala m'madambo achilengedwe; Anthu 17 ochokera ku mitundu iwiri yamitundu iwiri yokhazikika adagwiritsa ntchito madambo 83% ndi 90% yanthawiyo, apo ayi amagwiritsa ntchito minda. Zotsatirazi zikutsimikizira kafukufuku wam'mbuyomu wokhudzana ndi kuchepa kwa atsekwe aku China omwe akukhala m'nyengo yozizira ndi kuwonongeka kwa chilengedwe komanso kuwonongeka komwe kumayambitsa chakudya. Zotsatirazi zimathandiziranso kufotokoza za kusasunga bwino kwa atsekwe aku China akumazizira poyerekeza ndi mitundu ina ya tsekwe yomwe imakonda nyengo yachisanu kufupi ndi Korea ndi Japan, kumadzulo kwa Europe ndi North America, zomwe zimadyetsa pafupifupi nthaka yaulimi, kuwamasula ku malire achisanu.
