Abstract:

Mhuka dzinodavidza kunharaunda yadzo pazvikero zvepakati zvakawanda izvo chimwe nechimwe chinoda matanho ekuchengetedza akasiyana. Shiri dzeMvura ndiwo akakosha ezviratidzo zvezvipenyu zvepasi rose zvine njodzi asi nzira dzadzo dzekusarudza nzvimbo dzakasiyana-siyana hadzina kumbodzidzwa. Tichishandisa satellite yekutevera data uye Maximum entropy modelling, takadzidza kusarudzwa kwekugara kwemarudzi maviri ari kuderera eshiri dzemvura, Greater White-fronted Goose (Anser Albifrons) uye Tundra Bean Goose (A. serrirostris), pazviyero zvitatu zvepamhepo: landscape (30, 40, 50 km), 10, 10, roosting (10, 32 km), 10, 10, roosting (10, 32 km) 5 km). Isu takafungidzira kuti kusarudzwa kwenzvimbo yekugara kwainyanya kuenderana nemamiriro akakombama, ukuwo mamwe maratidziro enzvimbo akaverengerwa pakutsvagisa- uye kusarudzwa kwepekugara. Takaona kuti marudzi ese eshiri dzemumvura aifarira nzvimbo dzine chikamu chikuru chenzvimbo dzine matove nemvura dzinenge dziri pachiyero chenyika, mirwi yemvura yakaunganidzwa yakakomberedzwa neminda yakapararira pachiyero chekudya, uye nzvimbo dzemvura dzakanyatsobatanidzwa uye dzakanyatsobatanidzwa nepakati pemvura yepakati pakukura. Musiyano mukuru mukusarudzwa kwekugara kwemarudzi maviri aya wakaitika pachiyero chenyika uye chekudya; zvinhu pachiyero cheroosting zvakafanana. Tinokurudzira kuti mabasa ekuchengetedza anofanirwa kunangana nekusimudzira kuunganidzwa nekubatana kwemvura nenzvimbo dzine matoro, uye kugadzira ivhu rakaunganidzwa zvishoma munzvimbo dzakatenderedza. Nzira yedu inogona kutungamirira maitiro ekuchengetedza shiri dzemvura uye kutonga kwevhu nekupa matanho anoshanda ekuvandudza hutano hwekugara mukutarisana nekushandurwa kwezvakatipoteredza kunokonzerwa nevanhu.
