Abstract:

Kushanduka kwemamiriro ekunze kwave chikonzero chakakosha chekurasikirwa kwenzvimbo dzinogara shiri uye shanduko mukutama nekuberekana kweshiri. Hanzi chena-mberi kushoma (Anser erythropus) ine huwandu hwakasiyana hwekutama-tama uye yakanyorwa seyakasununguka paIUCN (International Union for Conservation of Nature) Red List. Muchidzidzo ichi, kugoverwa kwenzvimbo dzakakodzera dzekuberekera hanzi chena-mberi kwakaongororwa muSiberia, Russia, pachishandiswa musanganiswa wesatellite tracking uye data yekuchinja kwemamiriro ekunze. Hunhu hwekugovaniswa kwenzvimbo dzekuberekesa dzakakodzera pasi pemamiriro ekunze akasiyana mune ramangwana zvakafanotaurwa uchishandisa muenzaniso weMaxent, uye mapundu ekudzivirira akaongororwa. Ongororo iyi yakaratidza kuti pasi pemamiriro ekunze ekushanduka kwemamiriro ekunze, tembiricha uye kunaya kuchave iwo makuru emamiriro ekunze anokanganisa kugoverwa kwenzvimbo dzekuberekesa, uye nzvimbo yakabatana nenzvimbo dzakakodzera dzekuberekesa icharatidza kuderera kwemaitiro. Nzvimbo dzakanyorwa senzvimbo yekugara yakakwana inongoverengera 3.22% yekugoverwa kwakachengetedzwa; zvisinei, 1,029,386.341 km²yenzvimbo yakanaka yekugara yakaonekwa kunze kwenzvimbo yakachengetedzwa. Kuwana data yekugovera marudzi kwakakosha pakuvandudza kuchengetedza kwekugara munzvimbo dziri kure. Mhedzisiro yakapihwa pano inogona kupa hwaro hwekugadzira nzira dzemhando-chaiyo yekutarisira pekugara uye inoratidza kuti kumwe kutarisisa kunofanira kunangana pakuchengetedza nzvimbo dzakavhurika.
