Uhlobo (ilulwane):ama-swan e-whooper
Isifinyezo:
Ukukhethwa kwendawo yokuhlala kube yinto ebalulekile emvelweni yezilwane, ucwaningo lugxile kakhulu ekukhetheni indawo yokuhlala, ukusetshenziswa kwayo, kanye nokuhlolwa kwayo. Kodwa-ke, izifundo ezilinganiselwe esikalini esisodwa zivame ukwehluleka ukwembula izidingo zokukhethwa kwendawo yokuhlala yezilwane ngokugcwele nangokunembile. Leli phepha liphenya nge-whooper swan yasebusika (i-Cygnus cygnus) eManas National Wetland Park, eXinjiang, kusetshenziswa ukulandelela ngesathelayithi ukuthola izindawo zazo. Imodeli ye-Maximum Entropy (i-MaxEnt) yasetshenziswa ukuhlola izidingo zokukhethwa kwendawo yokuhlala eziningi ze-whooper swan yaseManas National Wetland Park ebusuku, emini, kanye nasezikalini zezwe. Lolu cwaningo lubonise ukuthi ukukhethwa kwendawo yokuhlala kwe-whooper swans yasebusika kwahlukahluka ngezikali ezahlukene. Esikalini sendawo, i-whooper swans yasebusika ikhetha izindawo zokuhlala ezinemvula ephakathi kuka-6.9 mm kanye namazinga okushisa aphakathi kuka-−6 °C, kufaka phakathi imizimba yamanzi kanye namanzi angaphansi komhlaba, okubonisa ukuthi isimo sezulu (imvula kanye nokushisa) kanye nohlobo lomhlaba (izindawo ezimanzi kanye nemizimba yamanzi) kuthonya ukukhethwa kwendawo yazo yokuhlala yasebusika. Emini, ama-whooper swans athanda izindawo eziseduze namaxhaphozi, imizimba yamanzi, kanye nomhlaba ongenalutho, lapho kusabalala khona imizimba yamanzi esakazeke kakhulu. Ebusuku, avame ukukhetha izindawo ezingaphakathi kwepaki lezindawo ezimanzi lapho ukuphazamiseka kwabantu kuncane khona futhi ukuphepha kuphakeme. Lolu cwaningo lunganikeza isisekelo sesayensi kanye nokusekelwa kwedatha kokulondolozwa kwendawo yokuhlala kanye nokuphathwa kwezinyoni zamanzi zasebusika njenge-whooper swans, kunconywa izinyathelo zokulondolozwa eziqondiwe zokuphatha nokuvikela ngempumelelo izindawo zasebusika zama-whooper swans.
