Izinhlobo (ilulwane):ama-whooper swans
Abstract:
Ukukhetha indawo yokuhlala kube yinto okugxilwe kuyo emvelweni wezilwane, ucwaningo lugxile kakhulu ekukhetheni indawo yokuhlala, ukusetshenziswa, nokuhlola. Kodwa-ke, ucwaningo olulinganiselwe esikalini esisodwa ngokuvamile luyehluleka ukuveza izidingo zokukhetha indawo yokuhlala yezilwane ngokugcwele nangokunembile. Leli phepha liphenya i-whooper swan yasebusika (Cygnus cygnus) e-Manas National Wetland Park, e-Xinjiang, isebenzisa ukulandelela ngesathelayithi ukuze kutholwe izindawo zayo. Imodeli ye-Maximum Entropy (MaxEnt) yasetshenziswa ukuze kuhlolwe izidingo zokukhetha indawo enezilinganiso eziningi zamadada asebusika e-Whooper e-Manas National Wetland Park phakathi nobusuku, emini, nesikali sendawo. Lolu cwaningo lubonise ukuthi ukukhethwa kwendawo okuhlala kuyo ama-whooper swans asebusika kuyahlukahluka ngezikali ezihlukene. Esikalini sokwakheka kwezwe, ama-whooper swans asebusika akhetha izindawo zokuhlala ezinesilinganiso sezulu sasebusika esingu-6.9 mm namazinga okushisa aphakathi kuka-−6 °C, okuhlanganisa izindawo ezinamanzi namaxhaphozi, okubonisa ukuthi isimo sezulu (imvula nezinga lokushisa) kanye nohlobo lwezwe (amaxhaphozi nezindawo ezinamanzi) kunomthelela ekukhetheni kwawo indawo yokuhlala yasebusika. Emini, ama-whooper swans ancamela izindawo eziseduze namaxhaphozi, izindawo ezinamanzi, nendawo engenalutho, enokusabalalisa okuhlakazeke kakhulu kwemithombo yamanzi. Ebusuku, bavame ukukhetha izindawo ezingaphakathi kwepaki lexhaphozi lapho ukuphazamiseka kwabantu kukuncane futhi ukuphepha kuphakeme. Lolu cwaningo lunganikeza isisekelo sesayensi kanye nokwesekwa kwedatha yokongiwa kwendawo kanye nokuphathwa kwezinyoni zasemanzini zasebusika njengama-whooper swans, okutusa izindlela zokongiwa ezihlosiwe zokuphatha nokuvikela ngempumelelo izindawo zasebusika zama-whooper swans.
Amagama angukhiye:I-cygnus cygnus; isikhathi sasebusika; ukukhetha indawo yokuhlala enezikali eziningi; I-Manas National Wetland Park
