Cov Lus Qhia Txog:
Kev hloov pauv huab cua tau dhau los ua ib qho tseem ceeb ua rau poob qhov chaw nyob ntawm cov noog thiab kev hloov pauv ntawm kev tsiv teb tsaws chaw ntawm cov noog thiab kev yug me nyuam. Tus qaib dawb-pem hauv ntej me dua (Anser erythropus) muaj ntau yam kev coj ua tsiv teb tsaws chaw thiab tau teev tseg tias yog qhov tsis muaj zog ntawm IUCN (International Union for Conservation of Nature) Red List. Hauv kev tshawb fawb no, kev faib tawm ntawm cov chaw yug me nyuam rau tus qaib dawb-pem hauv ntej me dua tau raug soj ntsuam hauv Siberia, Russia, siv kev sib xyaw ua ke ntawm kev taug qab satellite thiab cov ntaub ntawv hloov pauv huab cua. Cov yam ntxwv ntawm kev faib tawm ntawm cov chaw yug me nyuam tsim nyog nyob rau hauv ntau yam xwm txheej huab cua yav tom ntej tau kwv yees siv tus qauv Maxent, thiab qhov sib txawv ntawm kev tiv thaiv tau raug soj ntsuam. Kev tshuaj xyuas qhia tau hais tias nyob rau hauv keeb kwm yav dhau los ntawm kev hloov pauv huab cua yav tom ntej, qhov kub thiab nag yuav yog cov yam ntxwv tseem ceeb ntawm huab cua uas cuam tshuam rau kev faib tawm ntawm cov chaw yug me nyuam, thiab thaj chaw cuam tshuam nrog cov chaw yug me nyuam tsim nyog yuav nthuav tawm qhov sib txawv txo qis. Cov cheeb tsam teev tseg ua qhov chaw nyob zoo tshaj plaws tsuas yog suav rau 3.22% ntawm kev faib tawm tiv thaiv; txawm li cas los xij, 1,029,386.341 km22ntawm qhov chaw nyob zoo tshaj plaws tau pom sab nraum thaj chaw tiv thaiv. Kev tau txais cov ntaub ntawv faib tawm ntawm cov tsiaj txhu yog qhov tseem ceeb rau kev tsim kev tiv thaiv qhov chaw nyob hauv thaj chaw deb. Cov txiaj ntsig tau nthuav tawm ntawm no tuaj yeem muab lub hauv paus rau kev tsim cov tswv yim tswj hwm qhov chaw nyob tshwj xeeb rau cov tsiaj txhu thiab qhia tias yuav tsum tau saib xyuas ntxiv rau kev tiv thaiv qhov chaw qhib.
