Ijenali:Uphando lwezeNdalo, 34(5), iphe.637-643.

Iintlobo (zeentaka):IiWhooper swans (iCygnus cygnus)

Isishwankathelo:

Ukusetyenziswa kweendawo zokuhlala zezona zinto ziphambili kwi-ecology yeentaka, kwaye izifundo ngezi zinto ziya kuba luncedo ekugcinweni nasekulawulweni kweentaka. Iiswan ezingamashumi amathandathu anesixhenxe zaziyinkqubo yokubeka indawo kwihlabathi jikelele ephawulwe kwiSanmenxia Wetland yePhondo laseHenan ukuze zifumane idatha eneenkcukacha yendawo ebusika ukususela ngo-2015 ukuya ku-2016. Ubungakanani beendawo zokuhlala zeeswan yayiyeyona inkulu kwixesha eliphakathi lasebusika kwaye ilandelwa lixesha lokuqala nelisekupheleni kwexesha, kwaye ubukhulu bahluke kakhulu phakathi kwamaxesha amathathu asebusika. Kwakukho umahluko omkhulu ekusetyenzisweni kweendawo zokuhlala phakathi kwamaxesha ahlukeneyo asebusika. Kwixesha lokuqala, iiswan zazisebenzisa kakhulu ingca yasemanzini kunye neendawo zezityalo ezikhulayo, kwaye zazixhomekeke kakhulu ekuncedisweni okwenziweyo ngenxa yokungabikho kweendawo zokuhlala zendalo zokutya kwixesha eliphakathi. Kwixesha lokugqibela, iiswan zazisebenzisa kakhulu indawo yengca yomhlaba esandula ukuvela. Ngaphandle kwamanzi anzulu, ukusetyenziswa kwamanye amanqanaba amanzi kwakwahluke kakhulu phakathi kwamaxesha ahlukeneyo asebusika. Kwixesha lokuqala lasebusika, iiswan zazithanda iindawo ezinamanzi aphantsi naphezulu; kwixesha eliphakathi, zazikwiindawo ezinamanzi aphakathi naphezulu kwaye zazisebenzisa zonke iindawo ezinamanzi angaphantsi kwamanzi ngaphandle kwamanzi anzulu ngexesha lasebusika. Kwagqitywa kwelokuba ezinye izityalo zikhethwa zii-swans, ezifana neengcongolo, ii-cattails kunye nengca yasebarnyard, kwaye ubunzulu bamanzi bufanele bufanele ii-swans, kunye namanqanaba amanzi ahluka ngokwe-gradient.
