Ijenali:Izalathisi zeNdalo, 87, iphe.127-135.
Iintlobo (zeentaka):IGoose eNkulu emhlophe (Anser albifrons), iTundra Bean Goose (Anser serrirostris)
Isishwankathelo:
Izilwanyana ziyasabela kwindawo ezihlala kuyo ngezikali ezininzi zeendawo apho nganye ifuna amanyathelo ahlukeneyo okulondoloza. Iintaka zasemanzini zizibonakaliso ezibalulekileyo ze-bio kwiindawo ezimanzi ezisengozini yehlabathi kodwa iindlela zazo zokukhetha indawo yokuhlala ezininzi azikhange zifundwe rhoqo. Sisebenzisa idatha yokulandelela i-satellite kunye ne-Maximum entropy modeling, sifunde ukukhethwa kwendawo yokuhlala yeentlobo ezimbini zeentaka zasemanzini ezinciphayo, iGreater White-fronted Goose (Anser Albifrons) kunye neTundra Bean Goose (A. serrirostris), kwizikali ezintathu zeendawo: indawo (30, 40, 50 km), ukutya (10, 15, 20 km) kunye nokupaka (1, 3, 5 km). Sicinge ukuba ukukhethwa kwendawo yokuhlala ngokwesikali sendawo kwakusekelwe kakhulu kwimilinganiselo yeendawo ezimanzi, ngelixa iimpawu zeendawo ezineenkcukacha ngakumbi zithathelwe ingqalelo ekukhethweni kwendawo yokuhlala yokutya kunye nokupaka. Sifumanise ukuba zombini iintlobo zeentaka zasemanzini zikhetha iindawo ezinepesenti enkulu yeendawo ezimanzi nezimanzi kwisikali sendawo, iindawo zamanzi ezihlanganisiweyo ezijikelezwe ziindawo ezityaliweyo ezisasazekileyo kwisikali sokutya, kunye neendawo ezimanzi ezidibeneyo neziphakathi ezidibeneyo neziphakathi esikalini sokutya. Umahluko omkhulu ekukhetheni iindawo zokuhlala kwezi ntlobo zimbini wenzeke kwisikali sendawo nezitya zokutya; izinto kwisikali sokutya zazifana. Sicebisa ukuba imisebenzi yolondolozo mayigxile ekuphuculeni ukuhlanganiswa kunye nokunxibelelana kweendawo zamanzi nezimanzi, kunye nokuphuhlisa iindawo ezimanzi ezingahlanganisiweyo kakhulu kwindawo engqongileyo. Indlela yethu ingakhokela iindlela zokulondolozwa kweentaka zasemanzini kunye nolawulo lweendawo ezimanzi ngokubonelela ngamanyathelo asebenzayo okuphucula umgangatho weendawo zokuhlala xa kujongwe utshintsho olubangelwa ngabantu kwindalo esingqongileyo.
