Tshawb nrhiav thaj chaw tsis muaj kev yug me nyuam thiab txoj kev tsiv teb tsaws chaw ntawm Whimbrels (Numenius phaeopus rogachevae) hauv East Asian-Australasian Flyway.

Abstract:

Kev txiav txim siab txoj kev tsiv teb tsaws chaw thiab kev sib txuas ntawm cov noog tsiv teb tsaws chaw ntawm cov pej xeem pab qhia meej qhov sib txawv ntawm kev tsiv teb tsaws. Tsib subspecies tau raug lees paub hauv Whimbrel (Numenius phaeopus) hauv Eurasia. Ssp. rogachevae yog cov uas nyuam qhuav piav txog subspecies. Nws yug los nyob rau hauv Central Siberia, thaum nws cov cheeb tsam uas tsis yog yug me nyuam thiab txoj kev tsiv teb tsaws chaw tseem tsis meej. Peb tau taug qab kev tsiv teb tsaws chaw ntawm Eurasian Whimbrels raug ntes ntawm peb qhov chaw tsis muaj kev yug me nyuam (Moreton Bay nyob rau sab hnub tuaj ntug dej hiav txwv ntawm Australia, Roebuck Bay hauv Northwest Australia thiab Sungei Buloh Wetland hauv Singapore) thiab ob qhov chaw tsiv teb tsaws chaw (Chongming Dongtan thiab Mai Po Wetland hauv Suav teb). Peb tau txiav txim siab qhov chaw yug me nyuam thiab suav cov subspecies ntawm tagged noog nyob rau sab hnub tuaj Asian - Australasian Flyway (EAAF) raws li kev paub txog kev yug me nyuam ntawm txhua hom subspecies. Ntawm 30 tagged noog, 6 thiab 21 noog bred nyob rau hauv ntau yam ntawm ssp. rogachevae thiab variegatus, feem; ib tug bred nyob rau hauv lub presumed hloov chaw ntawm kev yug me nyuam ntau yam ntawm ssp. phaeopus thiab rogachevae, thiab ob bred nyob rau hauv cheeb tsam nruab nrab ntawm kev yug me nyuam ntawm ssp. rogachevae thiab variegatus. Cov noog uas yug hauv ssp. rogachevae kev yug me nyuam tau siv lawv lub caij tsis yug me nyuam nyob rau sab qaum teb Sumatra, Singapore, East Java thiab Northwest Australia thiab feem ntau nres hla Tuam Tshoj tus ntug dej hiav txwv thaum tsiv teb tsaws. Tsis muaj leej twg ntawm peb cov noog bred nyob rau hauv tshwj xeeb kev yug me nyuam ntawm phaeopus subspecies. Cov kev tshawb fawb yav dhau los tau kwv yees tias rogachevae whimbrels tsiv teb tsaws raws Central Asian Flyway thiab siv lub caij tsis muaj kev yug me nyuam hauv West India thiab East Africa. Peb pom tias tsawg kawg qee tus rogachevae whimbrels tsiv teb tsaws raws EAAF thiab siv lub caij tsis muaj kev yug me nyuam nyob rau sab hnub tuaj Asia thiab Australia. Cov ssp. phaeopus yog qhov zoo tshaj plaws sparsely faib nyob rau hauv EAAF nyob rau sab hnub poob cheeb tsam, los yog tejzaum nws tsis tshwm sim kiag li.
