Mhuka dzinopindura nharaunda yadzo pamatanho akasiyana-siyana enzvimbo ayo imwe neimwe inoda matanho akasiyana ekuchengetedza. Shiri dzemumvura ndidzo dzinoratidza zvipenyu zvikuru panjodzi yepasi rose yekuchengetedzwa kwenzvimbo dzemvura asi nzira dzadzo dzekusarudza nzvimbo dzemhuka dzakawanda hadzina kumbodzidzwa. Tichishandisa data rekutevera satellite uye Maximum entropy modeling, takadzidza kusarudzwa kwenzvimbo dzeshiri mbiri dzemumvura dziri kuramba dzichiderera, Greater White-fronted Goose (Anser Albifrons) uye Tundra Bean Goose (A. serrirostris), pamatanho matatu enzvimbo: nzvimbo (30, 40, 50 km), nzvimbo yekudya (10, 15, 20 km) uye nzvimbo yekudya (1, 3, 5 km). Takafungidzira kuti kusarudzwa kwenzvimbo dzemhuka kwakavakirwa zvakanyanya pamatanho akaomarara enzvimbo, nepo maitiro enzvimbo akadzama akatorwa mukusarudza nzvimbo dzemhuka dzemumvura nedzemumvura. Takaona kuti mhando dzese dzeshiri dzemumvura dzaida nzvimbo dzine huwandu hwakakura hwenzvimbo dzakanyorova nenzvimbo dzemvura pachiyero chenzvimbo, nzvimbo dzemvura dzakaunganidzwa dzakakomberedzwa nenzvimbo dzakapararira dzekurima pachiyero chekudya, nenzvimbo dzakanyorova dzakabatana zvakanaka nenzvimbo dzemvura dzepakati nepakati pachiyero chekudya. Musiyano mukuru mukusarudzwa kwenzvimbo dzemarudzi maviri aya wakaitika pachiyero chenzvimbo nechikamu chekudya; zvinhu pachiyero chekudya zvaive zvakafanana. Tinokurudzira kuti mabasa ekuchengetedza anofanirwa kutarisa pakuvandudza kuunganidzwa kwenzvimbo dzemvura nenzvimbo dzakanyorova, uye kugadzira nzvimbo dzisina kuunganidzwa zvakanyanya munzvimbo dzakakomberedza. Maitiro edu anogona kutungamira maitiro ekuchengetedza shiri dzemumvura nekutarisira nzvimbo dzakanyorova nekupa matanho anoshanda ekuvandudza hunhu hwenzvimbo dzekugara pasinei nekuchinja kwezvakatipoteredza kunokonzerwa nevanhu.
