Zvisikwa(Avian):Crane ine mutsipa mutema (Grus nigricollis)
Journal:Ecology uye Kuchengetedza
Abstract:
Kuti tizive ruzivo rwekusarudzwa kwekugara uye huwandu hwemba hwema cranes ane mitsipa mitema (Grus nigricollis) uye kuti mafuro anoapesvedzera sei, takaona nhengo dzevadiki dzevagari nekutevera satellite munzvimbo yeDanghe yeYanchiwan National Nature Reserve muGansu kubva 2018. kusvika 2020 mumwedzi yaChikunguru-Nyamavhuvhu. Population monitoring yakaitwawo panguva imwe cheteyo. Imba yemhando yakaverengerwa nekernel density estimation nzira. Zvadaro, takashandisa kududzira kwemifananidzo inonzwa kure nekudzidza kwemuchina kuona marudzi akasiyana ekugara munzvimbo yeDanghe. Manly's selection ratios uye random Forest model yakashandiswa kuongorora kusarudzwa kwepekugara muhukuru hwemba uye chiyero chekugara. Munzvimbo yekudzidza, mutemo wekudzora mafuro wakaitwa muna 2019, uye mhinduro yeBlack-necked cranes inoratidza seizvi: a) huwandu hwema cranes madiki akawedzera kubva pamakumi maviri nematatu kusvika makumi mashanu, izvo zvinoratidza hutongi hwemafuro hunokanganisa kusimba kwe cranes; b) Hutongi hwemafuro hwazvino haukanganise nzvimbo dzemusha uye kusarudzwa kwemhando dzekugara, asi zvinokanganisa mashandisirwo enzvimbo yecrane sezvo indekisi yekupindirana kwenzvimbo yemusha yaive 1.39% ± 3.47% uye 0.98% ± 4.15% mu2018 uye 2020 makore, zvichiteerana; c) Paive nekuwedzera kwemaitiro ekurevesa kwezuva nezuva kufamba chinhambwe uye nekukurumidza velocity inoratidza kugona kufamba kwekuwedzera kwema cranes madiki, uye chiyero cheakakanganisika cranes chinova chikuru; d) Dzvinyiriro dzevanhu hadzina zvazvinoita pakusarudza pekugara, uye makoni haatombokanganiswa nedzimba nemigwagwa parizvino. Makoni akasarudza madziva, asi achienzanisa nharaunda yemusha uye kusarudzwa kwenzvimbo yekugara, madhaka, rwizi nemakomo hazvigone kufuratirwa. Naizvozvo, isu tinotenda kuti kuenderera mberi nemutemo wekudzora mafuro kuchabatsira kudzikisira kupindirana kwedzimba uye zvozoderedza makwikwi emukati, uyezve zvinowedzera kuchengetedzwa kwekufamba kwema cranes madiki, uye pakupedzisira zvinowedzera huwandu hwevanhu. Uyezve, zvakakosha kutarisira zviwanikwa zvemvura uye kuchengetedza kugoverwa kuripo kwemigwagwa uye zvivakwa munzvimbo dzese dzematavi.
