Iintlobo (Intaka):IBustard Enkulu (Otis tarda)

Inkcazo:
I-Great Bustard (Otis tarda) ibambe eyona ntaka inzima ukuba ifuduke kunye neyona qondo likhulu le-dimorphism yezesondo phakathi kweentaka eziphilayo. Nangona ukufuduka kweentlobo kuye kwaxoxwa ngokubanzi kwiincwadi, abaphandi abazi kancinci malunga neepatheni zokufuduka kwee-subspecies zase-Asia (Otis tarda dybowskii), ngakumbi abesilisa. Ngo-2018 nango-2019, sabamba ii-O. dybowskii (amadoda amahlanu kunye nemazi enye) kwiindawo zabo zokuzalela kwimpuma yeMongolia kwaye bamakishe ngee-GPS-GSM satellite transmitters. Eli lixesha lokuqala ukuba i-Great Bustards ye-subspecies esempuma ilandelwe empuma yeMongolia. Sifumene iiyantlukwano zesini kwiipatheni zokufuduka: amadoda aqala ukufuduka kamva kodwa afika ngaphambi kowesifazane entwasahlobo; iinkunzi zine-1/3 yexesha lokufuduka kwaye zahamba malunga ne-1/2 umgama wemazi. Ukongeza, i-Great Bustards ibonise ukuthembeka okuphezulu kwiindawo zabo zokuzala, emva kokuzala, kunye neendawo zasebusika. Ukulondoloza, kuphela yi-22.51% yokulungiswa kwendawo ye-GPS yeebustards ezingaphakathi kweendawo ezikhuselweyo, kwaye zingaphantsi kwe-5.0% kwiindawo zasebusika nangexesha lokufuduka. Kwisithuba seminyaka emibini, isiqingatha seeGreat Bustards esizilandeleyo zafa kwiindawo zabo zasebusika okanye ngexesha lokufuduka. Sicebisa ukuba kusekwe iindawo ezikhuselweyo ezingakumbi kwiindawo zasebusika kunye nokuphinda kuthuthwe okanye kufakwe iintambo zombane ezingaphantsi komhlaba kwiindawo apho i-Great Bustards isasazwe ngokuxinana ukuphelisa ukungqubana.
