Cov Lus Qhia Txog:

Nees nkaum tus Far East Greylag Geese, Anser anser rubrirostris, raug ntes thiab nruab nrog Global Positioning System/Global System for Mobile Communications (GPS/GSM) loggers los txheeb xyuas cov chaw yug me nyuam thiab lub caij ntuj no, txoj kev tsiv teb tsaws chaw thiab qhov chaw nres. Cov ntaub ntawv Telemetry thawj zaug qhia txog kev sib txuas ntawm lawv cov chaw caij ntuj no ntawm Yangtze River, qhov chaw nres hauv sab qaum teb sab hnub tuaj Suav teb, thiab qhov chaw yug me nyuam/molting hauv sab hnub tuaj Mongolia thiab sab qaum teb sab hnub tuaj Suav teb. 10 ntawm 20 tus neeg uas tau cim npe tau muab cov ntaub ntawv txaus. Lawv tau nres thaum tsiv teb tsaws chaw ntawm Yellow River Estuary, Beidagang Reservoir thiab Xar Moron River, lees paub cov cheeb tsam no ua qhov chaw nres tseem ceeb rau cov pej xeem no. Lub sijhawm nruab nrab ntawm lub caij nplooj ntoo hlav tsiv teb tsaws chaw yog 33.7 hnub (cov tib neeg pib tsiv teb tsaws chaw ntawm 25 Lub Ob Hlis thiab 16 Lub Peb Hlis thiab ua tiav kev tsiv teb tsaws chaw ntawm 1 txog 9 Lub Plaub Hlis) piv rau 52.7 hnub thaum lub caij nplooj zeeg (26 Cuaj Hlis - 13 Lub Kaum Hli txog 4 Kaum Ib Hlis - 11 Lub Kaum Ob Hlis). Lub sijhawm nres nruab nrab yog 31.1 thiab 51.3 hnub thiab qhov ceev nruab nrab ntawm kev mus ncig yog 62.6 thiab 47.9 km / hnub rau kev tsiv teb tsaws chaw caij nplooj ntoos hlav thiab lub caij nplooj zeeg, raws li. Qhov sib txawv tseem ceeb ntawm kev tsiv teb tsaws chaw caij nplooj ntoos hlav thiab lub caij nplooj zeeg ntawm lub sijhawm tsiv teb tsaws chaw, lub sijhawm nres thiab qhov ceev ntawm kev tsiv teb tsaws chaw tau lees paub tias cov neeg laus Greylag Geese tau mus ncig sai dua thaum lub caij nplooj ntoos hlav dua li lub caij nplooj zeeg, txhawb nqa qhov kev xav tias lawv yuav tsum muaj sijhawm txwv ntau dua thaum lub caij nplooj ntoos hlav tsiv teb tsaws chaw.
