Izinhlobo (zezinyoni):Amahansi e-Swan (Anser cygnoides)
Ijenali:Ukuzwa Okukude
Isifinyezo:
Izindawo zokuhlala zinikeza indawo ebalulekile yezinyoni ezifudukayo ukuze ziphile futhi zizalane. Ukuhlonza izindawo zokuhlala ezingaba khona ezigabeni zomjikelezo waminyaka yonke kanye nezici zazo ezithonyayo kubalulekile ekulondolozweni kwendlela yokuhamba. Kulolu cwaningo, sithole ukulandelwa kwesathelayithi kwama-swan goese ayisishiyagalombili (ama-Anser cygnoides) ebusika eLake Poyang (28°57′4.2″, 116°21′53.36″) kusukela ngo-2019 kuya ku-2020. Sisebenzisa imodeli yokusatshalaliswa kwezinhlobo ze-Maximum Entropy, sihlole ukusatshalaliswa kwezindawo zokuhlala ezingaba khona zama-swan goese ngesikhathi somjikelezo wawo wokufuduka. Sihlaziye umnikelo ohlobene wezinto ezahlukahlukene zemvelo ekufanelekeni kwendawo yokuhlala kanye nesimo sokulondolozwa kwendawo ngayinye engaba khona endleleni yokuhamba. Imiphumela yethu ikhombisa ukuthi izindawo zokuqala zokuhlala zasebusika zama-swan goese zitholakala phakathi nendawo ephansi yoMfula iYangtze. Izindawo zokuma zazisakazeke kabanzi, ikakhulukazi eBohai Rim, ezindaweni eziphakathi zoMfula iYellow, kanye neNortheast Plain, futhi zanwetshwa ngasentshonalanga kuya e-Inner Mongolia naseMongolia. Izindawo zokuzalela ikakhulukazi zise-Inner Mongolia nasempumalanga yeMongolia, kanti ezinye zisakazeke enkabeni nasentshonalanga yeMongolia. Amazinga omnikelo wezici ezinkulu zemvelo ahlukile ezindaweni zokuzalela, izindawo zokuma, kanye nezindawo zasebusika. Izindawo zokuzalela zathonywa umthambeka, ukuphakama, kanye nokushisa. Umthambeka, inkomba yezinyawo zabantu, kanye nokushisa kwakuyizinto eziyinhloko ezithinte izindawo zokuma. Izindawo zasebusika zanqunywa ukusetshenziswa komhlaba, ukuphakama, kanye nemvula. Isimo sokulondolozwa kwezindawo zokuhlala singama-9.6% ezindaweni zokuzalela, ama-9.2% ezindaweni zasebusika, kanye nama-5.3% ezindaweni zokuma. Ngakho-ke okutholakele kwethu kunikeza ukuhlolwa okubucayi kwamazwe ngamazwe kokuvikelwa kwezindawo zokuhlala ezingaba khona zezinhlobo zamahansi ku-East Asian Flyway.
