Zvisikwa(Avian):Crane tsvuku-korona (Grus japonensis)
Abstract:
Matanho ekuchengetedza anobudirira anonyanya kutsamira paruzivo rwekusarudzwa kwepekugara kwemarudzi anotarisirwa. Zvishoma zvinozivikanwa nezve chiyero chehunhu uye rhythm yenguva yekusarudza kwekugara kweiyo iri mungozi yekutsakatika-korona crane, ichidzikamisa kuchengetedza kwekugara. Pano, ma cranes maviri ane korona-tsvuku akateverwa neGlobal position system (GPS) kwemakore maviri muYancheng National Nature Reserve (YNNR). Maitiro akawanda akagadzirwa kuti aone iyo spatiotemporal pateni yekusarudzwa kwekugara kwema cranes ane korona-tsvuku. Mhedzisiro yacho yakaratidza kuti Red-crown cranes anosarudza kusarudza Scirpus mariqueter, madziva, Suaeda salsa, uye Phragmites australis, uye kudzivirira Spartina alterniflora. Mumwaka wega wega, chiyero chekusarudza kwekugara kweScirpus mariqueter nemadziva chaive chepamusoro-soro masikati neusiku, zvichiteerana. Kuwedzera kuongororwa kwakasiyana-siyana kwakaratidza kuti chikamu chekuvhara kweScirpus mariqueter pa 200-m kusvika ku500-m scale ndiyo inonyanya kukosha kune yose yekusarudza kusarudzwa kwekugara, kusimbisa kukosha kwekudzorera nzvimbo yakakura yeScirpus mariqueter yekugara kwe red-crown crane restoration. Pamusoro pezvo, zvimwe zvinosiyana zvinokanganisa kusarudzwa kwekugara pazviyero zvakasiyana, uye mipiro yavo inosiyana nemwaka uye circadian rhythm. Uyezve, kukodzera kwenzvimbo yekugara kwakamepurwa kupa hwaro hwakananga hwekutarisira pekugara. Nzvimbo yakakodzera yekugara kwemasikati uye yehusiku yakaverengera 5.4% -19.0% uye 4.6% -10.2% yenzvimbo yekudzidza, zvichiteerana, zvichireva kukurumidza kwekudzorerwa. Chidzidzo chacho chakaratidza chiyero uye rhythm yenguva yekusarudza kwekugara kwemarudzi akasiyana-siyana ari mungozi anoenderana nenzvimbo diki dzekugara. Maonero akarongwa akasiyana-siyana anoshanda pakudzoreredza uye kutonga kwenzvimbo dzinogara mhuka dzakasiyana-siyana dziri mungozi.
