Abstract:

Kev paub meej txog hom kev sib raug zoo-ib puag ncig yog qhov tseem ceeb rau kev txhim kho cov tswv yim kev txuag thiab kho kom zoo. Txawm li cas los xij, txoj haujlwm no feem ntau nyuaj los ntawm qhov tsis muaj cov ncauj lus qhia ntxaws txog hom kev faib thiab thaj chaw nyob thiab nyiam tsis quav ntsej txog qhov cuam tshuam ntawm nplai thiab toj roob hauv pes. Ntawm no, peb tau taug qab 11 Oriental White Storks (Ciconia boyciana) nrog GPS loggers thaum lub caij ntuj no ntawm Poyang Lake thiab faib cov ntaub ntawv taug qab ua ob ntu (foraging thiab roosting states) raws li kev faib tawm ntawm kev ua haujlwm nyob rau ib hnub. Tom qab ntawd, peb-kauj ruam multiscale thiab multistate mus kom ze tau ua hauj lwm rau cov qauv kev xaiv vaj tse yam ntxwv: (1) ua ntej, peb txo qhov kev tshawb fawb ntau yam ntawm cov nplai rau ob lub xeev raws li cov yam ntxwv ntawm txhua hnub; (2) thib ob, peb txheeb xyuas qhov ua tau zoo ntawm txhua tus neeg sib tw sib txawv; thiab (3) thib peb, peb haum ib tug multiscale, multivariable chaw xaiv qauv nyob rau hauv relation mus rau tej yam ntuj tso nta, tib neeg cuam tshuam thiab tshwj xeeb tshaj yog cov toj roob hauv pes muaj pes tsawg leeg thiab configuration. Peb qhov kev tshawb pom qhia tias kev xaiv chaw nyob ntawm cov storks sib txawv nrog spatial scale thiab hais tias cov scaling kev sib raug zoo tsis zoo ib yam nyob rau hauv txawv qhov yuav tsum tau (foraging los yog roosting) thiab ib puag ncig nta. Kev teeb tsa toj roob hauv pes yog ib qho kev kwv yees muaj zog dua rau storks 'foraging chaw xaiv, thaum roosting yog rhiab heev rau toj roob hauv pes muaj pes tsawg leeg. Kev sib koom ua ke nrog cov ntaub ntawv muaj tseeb spatiotemporal satellite taug qab cov ntaub ntawv thiab cov duab toj roob hauv pes tau muab los ntawm cov duab satellite los ntawm tib lub sijhawm mus rau ntau qhov chaw xaiv cov qauv tuaj yeem txhim kho kev nkag siab ntawm hom tsiaj-ib puag ncig kev sib raug zoo thiab qhia kev npaj rov qab zoo thiab kev cai lij choj.
