Kufufuza kwa kagwiritsidwe ntchito ka mitundu ya ziweto zolusa n'kofunika kwambiri pa kasamalidwe ka kubwezeretsedwa kodziwa bwino. Anthu achikulire 16 a Milu (5♂11♀) adatsitsimutsidwanso kuchokera ku Jiangsu Dafeng Milu National Nature Reserve kupita ku Hunan East Dongting Lake National Nature Reserve pa February 28, 2016, pomwe anthu 11 a Milu (1♂10♀) anali atavala kolala yolondolera satellite ya GPS. Pambuyo pake, mothandizidwa ndi ukadaulo wa GPS wa kolala, kuphatikizidwa ndi zowonera pansi, tidatsata Milu yomwe idakhazikitsidwanso kwa chaka chimodzi kuyambira Marichi 2016 mpaka February 2017. Tidagwiritsa ntchito mtundu wa Brownian Bridge Movement Model kuyerekeza mtundu wapayokha wa Milu 10 yosinthidwanso (1♂9♀) chifukwa chosiyanitsidwa ndi nyengo yake yachikazi. Milu yachikazi yosinthika (yonse idatsatiridwa mpaka chaka chimodzi). Mulingo wa 95% umayimira mtundu wakunyumba, ndipo 50% idayimira madera oyambira. Kusintha kwakanthawi mu index yokhazikika ya zomera kunagwiritsidwa ntchito kuwerengera kusintha kwa kupezeka kwa chakudya. Tidawerengeranso kugwiritsa ntchito zida za Milu yosinthidwa powerengera kuchuluka kwa malo omwe amakhala m'malo awo oyambira. Zotsatira zinasonyeza kuti: (1) chiwerengero cha 52,960 chokonzekera chogwirizanitsa chinasonkhanitsidwa; (2) Kumayambiriro kwa kukonzanso, kukula kwanyumba kwa Milu yomwe idasinthidwa inali 17.62 ± 3.79 km.2ndipo pafupifupi madera apakati kukula kwake kunali 0.77 ± 0.10 km2; (3) kukula kwapachaka kwa mbawala yaikazi inali 26.08 ± 5.21 km2ndipo kukula kwapakati pazaka zapakati kunali 1.01 ± 0.14 km2pa chiyambi cha kusintha kwa thupi; (4) kumayambiriro kwa kukonzanso, malo amtundu wa nyumba ndi malo apakati a Milu yomwe inagwiritsidwanso ntchito inakhudzidwa kwambiri ndi nyengo, ndipo kusiyana pakati pa chilimwe ndi nyengo yozizira kunali kofunikira (kunyumba: p = 0.003; madera apakati: p = 0.008); (5) malo okhala ndi malo oyambira agwape aakazi omwe adasungidwanso m'dera la Dongting Lake munyengo zosiyanasiyana adawonetsa kusagwirizana kwakukulu ndi NDVI (kunyumba: p = 0.000; madera oyambira: p = 0.003); (6) Azimayi ambiri a Milu omwe adasamutsidwanso adawonetsa kukonda kwambiri minda m'nyengo zonse kupatula nyengo yachisanu, pomwe amaganizira kwambiri kugwiritsa ntchito nyanja ndi gombe. Kunyumba kwa Milu yomwe idasinthidwanso m'dera la Dongting Lake koyambirira kokonzanso zidasintha kwambiri nyengo. Kafukufuku wathu akuwonetsa kusiyana kwa nyengo m'manyumba a Milu yosinthidwanso komanso njira zogwiritsira ntchito zida za Milu payekha potengera kusintha kwa nyengo. Potsirizira pake, tinaika patsogolo malingaliro a kasamalidwe awa: (1) kukhazikitsa zilumba zokhalamo; (2) kukhazikitsa kasamalidwe ka anthu ammudzi; (3) kuchepetsa kusokonezeka kwa anthu; (4) kulimbikitsa kalondolondo wa chiwerengero cha anthu pokonza mapulani oteteza zachilengedwe.
