Abstract:
Lub Great Bustard (Otis tarda) tuav qhov sib txawv ntawm cov noog hnyav tshaj plaws los ua kev tsiv teb tsaws chaw nrog rau qhov loj tshaj plaws ntawm kev sib deev loj dimorphism ntawm cov noog nyob. Txawm hais tias kev tsiv teb tsaws ntawm cov tsiaj tau hais dav dav hauv cov ntaub ntawv, cov kws tshawb fawb paub me ntsis txog cov qauv kev tsiv teb tsaws ntawm cov subspecies hauv Asia (Otis tarda dybowskii), tshwj xeeb tshaj yog cov txiv neej. Hauv 2018 thiab 2019, peb ntes tau rau O. t. dybowskii (tsib tus txiv neej thiab ib tug poj niam) ntawm lawv qhov chaw yug me nyuam nyob rau sab hnub tuaj Mongolia thiab tagged lawv nrog GPS-GSM satellite transmitters. Qhov no yog thawj zaug uas Great Bustards ntawm sab hnub tuaj subspecies tau taug qab nyob rau sab hnub tuaj Mongolia. Peb pom qhov sib txawv ntawm kev sib deev hauv cov qauv kev tsiv teb tsaws: cov txiv neej pib tsiv teb tsaws tom qab tab sis tuaj txog ntxov dua tus poj niam nyob rau lub caij nplooj ntoo hlav; Cov txiv neej muaj 1/3 ntawm lub sij hawm tsiv teb tsaws chaw thiab tsiv teb tsaws txog 1/2 qhov kev ncua deb ntawm tus poj niam. Tsis tas li ntawd, Great Bustards tau nthuav tawm kev ntseeg siab rau lawv qhov kev yug me nyuam, tom qab yug me nyuam, thiab lub caij ntuj no. Rau kev txuag, tsuas yog 22.51% ntawm GPS qhov chaw kho ntawm bustards nyob hauv thaj chaw tiv thaiv, thiab tsawg dua 5.0% rau cov chaw caij ntuj no thiab thaum tsiv teb tsaws. Hauv ob xyoos, ib nrab ntawm Great Bustards peb taug qab tau tuag ntawm lawv qhov chaw caij ntuj no lossis thaum tsiv teb tsaws. Peb pom zoo kom tsim kom muaj kev tiv thaiv ntau dua ntawm cov chaw nyob rau lub caij ntuj no thiab rov qab los yog cov kab hluav taws xob hauv av hauv cov cheeb tsam uas Great Bustards tau faib ua ntau ntom ntom kom tshem tawm kev sib tsoo.
