Izinhlobo (Izinyoni):I-Greater White-fronted Geese (Anser albifrons)
Abstract:
Ithiyori yokufuduka iphakamisa, kanye nocwaningo oluthile olubonisa ukuthi, ukuze kuqhudelane iziza ezingcono kakhulu zokuzalanisa futhi kwandiswe impumelelo yokuzala, abafuduki bezindiza ezikude bavame ukusebenzisa isu lokunciphisa isikhathi phakathi nokufuduka kwentwasahlobo, okuholela ekufudukeni kwentwasahlobo okufushane uma kuqhathaniswa nalokho ekwindla. Sisebenzisa izithumeli ze-GPS/GSM, silandelele ukufuduka okugcwele kwe-Greater White-fronted Geese (Anser albifrons) phakathi kwaseningizimu-mpumalanga ye-China ne-Arctic yase-Russian, ukuveza isikhathi sokufuduka nezindlela zabantu base-East Asia, futhi siqhathanise umehluko wesikhathi phakathi kokufuduka kwentwasahlobo nasekwindla kwalesi sibalo. Sithole ukuthi ukufuduka entwasahlobo (izinsuku ezingama-79 ± 12) kuthatha isikhathi esingaphezu kokuphindwe kabili ukumboza ibanga elifanayo nelasekwindla (izinsuku ezingama-35 ± 7). Lo mehluko obude besikhathi sokufuduka wanqunywa ngokuphawulekayo isikhathi esiningi esichithwa entwasahlobo (izinsuku ezingu-59 ± 16) kunasekwindla (izinsuku ezingu-23 ± 6) ezindaweni eziningi zokuma. Siphakamisa ukuthi lawa mahansi, okucatshangwa ukuthi angabafuyi bezimali ngokwengxenye, achithe cishe izingxenye ezintathu kwezine zesikhathi esiphelele sokufuduka ezindaweni zokuma kwentwasahlobo ukuze athole izitolo zamandla ukuze atshale imali ekugcineni ekukhiqizeni, nakuba singenakuwenqaba umbono wokuthi isikhathi sokuncibilika kwentwasahlobo nakho kube nomthelela ekumisweni kwesikhathi. Ekwindla, bathola izitolo zamandla adingekayo ezindaweni zokuzalanisa ezanele ukufinyelela ezindaweni zesiteji eNyakatho-mpumalanga yeChina cishe ngaphandle kokuma, okwanciphisa izikhathi zokuma ekwindla futhi kwaholela ekufudukeni kwekwindla ngokushesha kunentwasahlobo.
