Cov Lus Qhia Txog:

Tus noog Great Bustard (Otis tarda) yog tus noog hnyav tshaj plaws uas tau tsiv teb tsaws chaw thiab muaj qhov sib txawv ntawm cov poj niam txiv neej ntawm cov noog uas muaj sia nyob. Txawm hais tias kev tsiv teb tsaws chaw ntawm hom tsiaj no tau tham txog ntau yam hauv cov ntaub ntawv, cov kws tshawb fawb paub me ntsis txog cov qauv kev tsiv teb tsaws chaw ntawm cov subspecies hauv Asia (Otis tarda dybowskii), tshwj xeeb tshaj yog cov txiv neej. Xyoo 2018 thiab 2019, peb tau ntes rau tus O. t. dybowskii (tsib tus txiv neej thiab ib tus poj niam) ntawm lawv qhov chaw yug me nyuam hauv sab hnub tuaj Mongolia thiab tau muab GPS-GSM satellite transmitters rau lawv. Qhov no yog thawj zaug uas Great Bustards ntawm cov subspecies sab hnub tuaj tau raug taug qab hauv sab hnub tuaj Mongolia. Peb pom qhov sib txawv ntawm poj niam txiv neej hauv cov qauv kev tsiv teb tsaws chaw: cov txiv neej pib tsiv teb tsaws chaw tom qab tab sis tuaj txog ua ntej tus poj niam thaum lub caij nplooj ntoo hlav; cov txiv neej muaj 1/3 ntawm lub sijhawm tsiv teb tsaws chaw thiab tsiv teb tsaws chaw li 1/2 qhov deb ntawm tus poj niam. Tsis tas li ntawd, Great Bustards tau ua pov thawj siab rau lawv qhov kev yug me nyuam, tom qab yug me nyuam, thiab qhov chaw nyob rau lub caij ntuj no. Rau kev txuag, tsuas yog 22.51% ntawm GPS qhov chaw kho ntawm cov bustards nyob hauv thaj chaw tiv thaiv, thiab tsawg dua 5.0% rau cov chaw nyob rau lub caij ntuj no thiab thaum lub sijhawm tsiv teb tsaws chaw. Hauv ob xyoos, ib nrab ntawm cov Great Bustards uas peb taug qab tau tuag ntawm lawv cov chaw nyob rau lub caij ntuj no lossis thaum lub sijhawm tsiv teb tsaws chaw. Peb xav kom tsim kom muaj ntau thaj chaw tiv thaiv ntawm cov chaw nyob rau lub caij ntuj no thiab hloov txoj kev lossis tso cov xov hluav taws xob hauv av hauv thaj chaw uas Great Bustards tau faib ua pawg kom tsis txhob muaj kev sib tsoo.
