Isalathisi esitsha esisekwe kwisathelayithi ukuchonga iindawo ezifuna ukutya ezifumaneka kwi-Spatiotemporal kwi-herbivorous waterfowl.

Ijenali:Izalathisi ze-Ecological, i-99, iphepha 83-90.

Iintlobo (Intaka):Irhanisi elingaphambili elimhlophe (Anser albifrons)

Inkcazo:

Ukusasazwa kobutyebi bokutya ngumba ophambili ekukhetheni indawo yokuhlala. Iintaka ezikhula emanzini zikhetha izityalo ezikwinqanaba lakwangoko (ukusuka ekuqaleni kokukhula kwezityalo ukuya kwincopho yezakha mzimba) njengoko ezi zinika amazinga aphezulu okuthathwa kwamandla. Eli nqanaba lophuhliso lwezityalo alibanjwanga ngokupheleleyo zizalathisi zezityalo eziphuma kwisathelayithi ezisetyenziswa ngokuqhelekileyo, ezigxininisa kwi-biomass yezityalo (umzekelo, i-Enhance Vegetation Index, i-EVI) okanye ukukhula kwezityalo okusebenzayo (umzekelo, umahluko we-EVI phakathi komhla wangoku kunye nomhla wangaphambili, i-diffEVI). Ukuphucula imephu yeendawo ezifanelekileyo zokutyisa iintaka zasemanzini, sicebisa isalathisi esitsha sokukhula kwesityalo esisekwe kwisathelayithi sokukhula kwezityalo kwisigaba sakwangoko (ESPG). Siqikelela ukuba iintaka zasemanzini eziziintaka ezitya ukhula zikhetha izityalo ezikwinqanaba lokuqala lokukhula kwaye zikhethe izityalo ezinokuphela kwexesha le-ESPG ngexesha elingakhuliyo. Sisebenzisa idatha yokulandelela ngesathelayithi yamarhanisi angama-20 angaphambili amhlophe (Anser albifrons) ebusika kumlambo waseYangtze ukuze siqinisekise uqikelelo lwethu. Sakha imifuziselo elungeleleneyo eqhelekileyo yokuhanjiswa kwerhanisi ngexesha lokukhula kunye namaxesha onyaka angakhuliyo kwaye sithelekise ukusebenza kwe-ESPG kwizikhombisi ezisetyenziswa ngokuqhelekileyo zokukhula kwezityalo (EVI kunye ne-diffEVI). Ngexesha lokukhula, i-ESPG inokuchaza i-53% yokwahluka kwi-goose distribution, i-EVI egqwesileyo (27%) kunye ne-diffEVI (34%). Ngethuba lexesha elingakhuliyo, kuphela ukuphela kwe-ESPG kuchaphazela kakhulu ukuhanjiswa kwe-goose, kuchaza i-25% yokuhluka (ESPG: AUC = 0.78; EVI: AUC = 0.58; diffEVI: AUC = 0.58). Isalathisi esitsha sokukhula kwesityalo esaphuhliswayo i-ESPG sinokusetyenziselwa ukuphucula iimodeli zokusasazwa kweentaka zasemanzini ezitya utyani kwaye yiyo loo nto ixhasa iinzame zokulondoloza iintaka zamanzi kunye nolawulo lomgxobhozo.
