Iintlobo (zeentaka):I-Great Bustard (Otis tarda)
IjenaliJ:iphephandaba le-Ornithology
Isishwankathelo:
I-Great Bustard (Otis tarda) ibamba indawo ephambili njengentaka enzima kakhulu ukufuduka kunye nenqanaba eliphezulu lokungafani ngobukhulu besondo phakathi kweentaka eziphilayo. Nangona ukufuduka kolu hlobo kuye kwaxoxwa kakhulu kwiincwadi, abaphandi abazi nto ingako malunga neendlela zokufuduka kolu hlobo lwezilwanyana e-Asia (Otis tarda dybowskii), ingakumbi iinkunzi. Ngo-2018 nango-2019, sabamba ii-O. t. dybowskii ezintandathu (iinkunzi ezintlanu kunye nemazi enye) kwiindawo zazo zokuzalela empuma yeMongolia saza saziphawula ngee-GPS-GSM satellite transmitters. Eli lixesha lokuqala ukuba ii-Great Bustard zeentlobo zezilwanyana zasempuma zilandelwe empuma yeMongolia. Sifumene umahluko wesini kwiindlela zokufuduka: iinkunzi zaqala ukufuduka kamva kodwa zafika ngaphambi kwemazi entwasahlobo; iinkunzi zazine-1/3 yexesha lokufuduka kwaye zafuduka malunga ne-1/2 yomgama wemazi. Ukongeza, ii-Great Bustards zibonakalise ukuthembeka okuphezulu kwiindawo zazo zokuzalela, emva kokuzalela, kunye neendawo zasebusika. Kwindawo yokugcina indalo, yi-22.51% kuphela yokulungiswa kwendawo ye-GPS yee-bustard ezazikwiindawo ezikhuselekileyo, kwaye zingaphantsi kwe-5.0% kwiindawo zasebusika nangexesha lokufuduka. Kwiminyaka emibini, isiqingatha see-Great Bustard esasizilandele safa kwiindawo zazo zasebusika okanye ngexesha lokufuduka. Sicebisa ukuba kusekwe iindawo ezikhuselekileyo ngakumbi kwiindawo zasebusika kunye nokutshintsha indlela okanye ukufaka imigca yombane phantsi komhlaba kwiindawo apho ii-Great Bustard zisasazeke kakhulu ukuze kuthintelwe ukungqubana.
