Iipateni zokufuduka kwentwasahlobo, ukusetyenziswa kwendawo yokuhlala, kunye nemeko yokukhuselwa kwendawo yokuma kweentlobo ezimbini zeentaka zasemanzini ezinciphayo ezihlala ebusika eTshayina njengoko kutyhilwe yi-satellite tracking.

Ijenali:I-Ecology kunye ne-Evolution, 8(12), iphe.6280-6289.

Iintlobo (zeentaka):IGoose eNkulu emhlophe (Anser albifrons), iTundra Bean Goose (Anser serrirostris)

Isishwankathelo:

Iintaka zasemanzini ezifudukayo zaseMpuma Asia ziye zehla kakhulu ukusukela ngeminyaka yoo-1950, ingakumbi abemi basebusika eTshayina. Ulondolozo luthintelwa kakhulu kukungabikho kolwazi oluphambili malunga neendlela zokufuduka kunye neendawo zokuma. Olu phononongo lusebenzisa iindlela zokulandelela iisathelayithi kunye nohlalutyo oluphambili lwendawo ukuphanda ukufuduka kwentwasahlobo kwehashe elikhulu elimhlophe (Anser albifrons) kunye nehashe le-tundra bean (Anser serrirostris) ebusika ecaleni kweYangtze River Floodplain. Ngokusekelwe kwimizila engama-24 efunyenwe kwizilwanyana ezingama-21 ngexesha lentwasahlobo ka-2015 no-2016, sifumanise ukuba iNortheast China Plain yeyona ndawo yokuma esetyenziswa kakhulu ngexesha lokufuduka, apho amahashe ehlala ixesha elingaphezu kwenyanga e-1. Lo mmandla ukwaphuhliswe kakhulu kwezolimo, nto leyo ebonisa ukuba kukho unxibelelwano olubangela ukwehla kweentaka zasemanzini zaseMpuma Asia ezihlala ebusika eTshayina. Ukukhuselwa kwamanzi asetyenziswa njengendawo yokulala, ingakumbi lawo ajikelezwe yindawo yokutya kakhulu, kubalulekile ekusindeni kweentaka zasemanzini. Ngaphezulu kwe-90% yendawo ephambili esetyenziswa ngexesha lokufuduka kwentwasahlobo ayikhuselekanga. Sicebisa ukuba uphando lomhlaba oluzayo lufanele lujolise kwezi ndawo ukuqinisekisa ukubaluleka kwazo kwiintaka zasemanzini ezifudukayo kwinqanaba labemi, kwaye indawo yokuhlala ephambili kwiindawo ezibalulekileyo zokukhulisa intwasahlobo kufuneka idityaniswe kwinethiwekhi yeendawo ezikhuselweyo ecaleni kwendlela. Ngaphezu koko, ingxabano enokubakho phakathi kweentaka nabantu kwindawo yokuma ephakathi kufuneka ifundwe ngakumbi. Uphononongo lwethu lubonisa indlela ukulandelwa kwesathelayithi kunye nohlalutyo lwendawo okunokubonelela ngayo ngengqiqo ebalulekileyo efunekayo ukuphucula ulondolozo lweentlobo ezifudukayo ezinciphayo.
