Iintlobo (ilulwane):ii-whooper swans
Isishwankathelo:
Ukukhethwa kweendawo zokuhlala kube yeyona nto iphambili kwi-ecology yezilwanyana, uphando lugxile kakhulu ekukhetheni indawo yokuhlala, ukusetyenziswa kwayo, kunye novavanyo. Nangona kunjalo, izifundo ezilinganiselwe kwisikali esinye zihlala zingaphumeleli ukutyhila iimfuno zokukhethwa kwendawo yokuhlala yezilwanyana ngokupheleleyo nangokuchanekileyo. Eli phepha liphanda i-whooper swan yasebusika (i-Cygnus cygnus) eManas National Wetland Park, eXinjiang, kusetyenziswa umkhondo wesathelayithi ukumisela iindawo ezikuzo. Imodeli ye-Maximum Entropy (i-MaxEnt) isetyenziswe ukuhlola iimfuno zokukhethwa kwendawo yokuhlala ezininzi ze-whooper swans yasebusika yaseManas National Wetland Park ebusuku, emini, nakwizikali zomhlaba. Olu phononongo lubonise ukuba ukhetho lweendawo zokuhlala ze-whooper swans yasebusika lwahluka ngezikali ezahlukeneyo. Kwisikali sendawo, i-whooper swans yasebusika ikhetha iindawo zokuhlala ezinemvula ephakathi yasebusika eyi-6.9 mm kunye namaqondo obushushu aphakathi ayi-−6 °C, kubandakanya imizimba yamanzi kunye neendawo ezimanzi, okubonisa ukuba imozulu (imvula kunye nobushushu) kunye nohlobo lomhlaba (imimandla emanzi kunye neendawo zamanzi) zichaphazela ukhetho lwazo lweendawo zokuhlala zasebusika. Emini, ii-whooper swans zithanda iindawo ezikufutshane neendawo ezimanzi, iindawo zamanzi, nomhlaba ongenanto, apho kukho ukusasazwa kwamanzi amaninzi. Ebusuku, zihlala zikhetha iindawo ezikwipaki yamanzi apho ukuphazamiseka kwabantu kuncinci kwaye ukhuseleko luphezulu. Olu phononongo lunokubonelela ngesiseko sesayensi kunye nenkxaso yedatha yokulondolozwa kwendawo yokuhlala kunye nolawulo lweentaka zamanzi zasebusika ezifana nee-whooper swans, zicebisa amanyathelo olondolozo ajoliswe kuwo ukulawula nokukhusela ngokufanelekileyo iindawo zasebusika zee-whooper swans.
Amagama angundoqo:I-cygnus cygnus; ixesha lasebusika; ukhetho lweendawo zokuhlala ezininzi; iManas National Wetland Park
