Kala duwanaanshaha xilliyeed ee noocyada guriga ee Milu ee marxaladda hore ee dib-u-warshadaynta ee aagga Harada Dongting, Shiinaha.

Noocyada (Xayawaanada):Milu(Elaphurus davidianus)

Joornaal:Deegaanka Caalamiga ah iyo Ilaalinta

Soo Koobid:

Daraasadda ku saabsan isticmaalka xayawaanka dib loo soo celiyay ee guryaha ayaa muhiim u ah maaraynta dib-u-soo-celinta xogta leh. Lix iyo toban qof oo qaangaar ah oo Milu ah (5♂11♀) ayaa dib looga soo saaray Kaydka Dabeecadda Qaranka ee Jiangsu Dafeng Milu una wareejiyay Kaydka Dabeecadda Qaranka ee Hunan East Dongting Lake Febraayo 28, 2016, kuwaas oo 11 qof oo Milu ah (1♂10♀) ay xirnaayeen qoollo raadraaca dayax-gacmeedka GPS. Kadib, iyadoo la kaashanayo tignoolajiyada qoollo-gacmeedka GPS, oo ay weheliso indha-indheynta raadraaca dhulka, waxaan la soconay Milu-gii dib loo soo saaray hal sano laga bilaabo Maarso 2016 ilaa Febraayo 2017. Waxaan isticmaalnay Qaabka Dhaqdhaqaaqa Buundada Brownian ee firfircoon si aan u qiyaasno tirada guryaha ee 10ka Milu ee dib loo soo celiyay (1♂9♀, 1 qof oo dumar ah ayaa la tirtiray sababtoo ah qoollo-gacmeedkiisu wuu dhacay) iyo tirada guryaha xilliyeed ee 5 Milu oo dumar ah oo dib loo soo celiyay (dhammaantoodna la raad-raacay ilaa hal sano). Heerka 95% wuxuu ahaa tirada guryaha, heerka 50% wuxuu ahaa meelaha ugu muhiimsan. Kala duwanaanshaha ku meel gaarka ah ee tusmada dhirta ee kala duwanaanshaha caadiga ah ayaa loo isticmaalay in lagu cabbiro isbeddellada helitaanka cuntada. Waxaan sidoo kale cabbirnay isticmaalka kheyraadka ee Milu-ga dib loo rogay annagoo xisaabinayna saamiga xulashada dhammaan deegaannada ku jira aagagga asaasiga ah. Natiijooyinka waxay muujiyeen in: (1) wadarta 52,960 hagaajin isku-dhafan ayaa la ururiyay; (2) inta lagu jiro marxaladda hore ee dib-u-warshadaynta, celceliska cabbirka guriga ee Milu-ga dib loo rogay wuxuu ahaa 17.62 ± 3.79 km²cabbirka celceliska aagagga xudunta ah wuxuu ahaa 0.77 ± 0.10 km²; (3) celceliska cabbirka sanadlaha ah ee guryaha deerada dheddigga ah wuxuu ahaa 26.08 ± 5.21 km²celceliska sanadlaha ah ee cabbirka aagagga xudunta ah wuxuu ahaa 1.01 ± 0.14 km²Marxaladdii hore ee dib-u-warshadaynta; (4) intii lagu jiray marxaladdii hore ee dib-u-warshadaynta, kala duwanaanshaha guriga iyo meelaha muhiimka ah ee Milu-ga dib-u-warshadaynta ayaa si weyn u saameeyay xilliga, farqiga u dhexeeya xagaaga iyo jiilaalkana wuxuu ahaa mid muhiim ah (kala duwanaanshaha guriga: p = 0.003; meelaha muhiimka ah: p = 0.008); (5) kala duwanaanshaha guriga iyo meelaha muhiimka ah ee deerada dheddigga ah ee dib-u-warshadaynta ee aagga Harada Dongting xilliyo kala duwan ayaa muujiyay xiriir taban oo muhiim ah oo lala leeyahay NDVI (kala duwanaanshaha guriga: p = 0.000; meelaha muhiimka ah: p = 0.003); (6) Milu-ga dheddigga ah ee ugu badan ee dib-u-warshadaynta ayaa muujiyay doorbid sare oo dhul beereed ah xilli kasta marka laga reebo jiilaalka, markii ay diiradda saareen isticmaalka harada iyo xeebta. Kala duwanaanshaha guriga ee Milu-ga dib-u-warshadaynta ee aagga Harada Dongting marxaladdii hore ee dib-u-warshadaynta waxay la kulmeen isbeddello xilliyeed oo aad u weyn. Daraasaddeennu waxay muujinaysaa kala duwanaanshaha xilliyeed ee heerarka guriga ee Milu-ga dib-u-warshadaynta iyo istaraatiijiyadaha isticmaalka kheyraadka ee Milu-ga shaqsiga ah si looga jawaabo isbeddellada xilliyeed. Ugu dambeyntii, waxaan soo bandhignay talooyinka maaraynta ee soo socda: (1) in la dhiso jasiirado deegaan; (2) in la hirgeliyo maamul wadaag ah oo bulshada ah; (3) in la yareeyo khalkhalka aadanaha; (4) in la xoojiyo la socodka dadweynaha si loo sameeyo qorshayaasha ilaalinta noocyada.
