Isishwankathelo:
Ithiyori yokufuduka ibonisa, kwaye ezinye izifundo ezisekelwe kubungqina zibonisa, ukuba ukuze kukhuphisane ngeendawo zokuzalela ezilungileyo kwaye kwandiswe impumelelo yokuzala, abafuduki beentaka abahambela umgama omde badla ngokusebenzisa icebo lokunciphisa ixesha ngexesha lokufuduka kwentwasahlobo, nto leyo ebangela ukufuduka kwexesha elifutshane kwentwasahlobo xa kuthelekiswa noko kwenzeka ekwindla. Sisebenzisa ii-GPS/GSM transmitters, silandelele ukufuduka okupheleleyo kwee-11 Greater White-fronted Geese (Anser albifrons) phakathi komzantsi-mpuma weTshayina kunye ne-Russian Arctic, ukuze sityhile ixesha lokufuduka kunye neendlela zabemi baseMpuma Asia, kwaye sithelekise umahluko kwixesha phakathi kokufuduka kwentwasahlobo kunye nokwindla kwale qela. Sifumanise ukuba ukufuduka entwasahlobo (iintsuku ezingama-79 ± 12) kuthathe ixesha eliphindwe kabini ukugubungela umgama ofanayo nowasekwindla (iintsuku ezingama-35 ± 7). Lo mahluko kwixesha lokufuduka umiselwe kakhulu lixesha elichithwe kakhulu entwasahlobo (iintsuku ezingama-59 ± 16) kunasekwindla (iintsuku ezingama-23 ± 6) kwiindawo zokuma ezithe kratya. Sicebisa ukuba la mahansi, ekucingelwa ukuba angabavelisi bemali abancinane, achithe phantse iikota ezintathu zexesha lokufuduka kwiindawo zokuma entwasahlobo ukuze afumane iindawo zokugcina amandla ukuze atyale imali eninzi ekuzaleni, nangona singenakuyikhanyela ingcamango yokuba ixesha lokunyibilika kwentwasahlobo nalo linegalelo kwixesha lokuma. Ekwindla, afumana iindawo zokugcina amandla ezifunekayo kwiindawo zokuzalela ezaneleyo ukufikelela kwiindawo zokubeka izilwanyana zaseMntla-mpuma China phantse ngaphandle kokuma, nto leyo eyanciphisa amaxesha okuma ekwindla kwaye yabangela ukufuduka kwekwindla ngokukhawuleza kunentwasahlobo.
