Izinhlobo (Izinyoni):I-Hooded Crane (Grus monacha)

Abstract:

I-Hooded Crane (Grus monacha) ifakwe ohlwini lwezilwane ezisengozini yi-IUCN. Ulwazi mayelana nokufuduka kwe-Hooded Crane lusalinganiselwe. Lapha sibike amaphethini okufuduka kwesikhashana kwesikhathi se-Hooded Cranes ebusika e-Izumi, e-Japan, kanye nezindawo ezibalulekile zokuma ukuze zigcinwe. Okhreyini abane abadala nabahlanu, bonke basebusika e-Izumi, e-Japan, bafakelwe ama-satellite transmitters (GPS–GSM system) ezindaweni zabo zokuma enyakatho-mpumalanga ye-China kanye nesikhathi sabadala sika-20154. abantu abadala abafudukayo entwasahlobo nasekwindla, kanye nesikhathi nobude abasihlala endaweni yokuzalela kanye nobusika. Ngaphezu kwalokho, sihlaziye ukusetshenziswa komhlaba kwama-cranes ezindaweni zokuma. Okhreyini abadala bathathe isikhathi eside kakhulu ukuthuthela enyakatho entwasahlobo (okusho = izinsuku ezingu-44.3) naseningizimu ekwindla (okusho = izinsuku ezingu-54.0) uma kuqhathaniswa nama-cranes angaphansi (izinsuku ezingu-15.3 nezi-5.2, ngokulandelana). Kodwa-ke, ama-subadults ayenobusika obude (okusho = izinsuku ezingu-149.8) kanye nezinkathi zonyaka (inkathi yokuzalanisa yabantu abadala) (okusho = izinsuku ezingu-196.8) uma kuqhathaniswa nabantu abadala (izinsuku ezingu-133.8 nezingu-122.3, ngokulandelana). Sezikhonjwe izindawo ezintathu ezibalulekile zokuma: isifunda esizungeze i-Muraviovka Park e-Russia, i-Songnen Plain e-China, kanye nogu olusentshonalanga ye-South Korea, lapho ama-cranes achitha isikhathi esiningi sokufuduka kwawo (ama-62.2 kanye nama-85.7% entwasahlobo nasekwindla, ngokulandelana). Ngesikhathi sokufuduka, isikhathi sokuzulazula kanye nobusika, ama-Hooded Cranes ngokuvamile ahlala ezindaweni zokutshala ukuze aphumule futhi adliwe. Ngesizini okungeyona eyobusika, ngaphansi kuka-6% wezindawo zokuma bezitholakala ezindaweni ezivikelekile. Sekukonke, imiphumela yethu inomthelela ekuqondeni amaphethini onyaka wokufuduka kwe-spatio-temporal we-Hooded Cranes kundiza esempumalanga, kanye nokuhlela izindlela zokulondoloza lolu hlobo lwezilwane.
