Iintlobo (Izilwanyana):Milu(Elaphurus davidianus)

Ijenali:I-Ecology yeHlabathi kunye noLondolozo

Inkcazo:

Uphononongo lokusetyenziswa koluhlu lwamakhaya lwezilwanyana ezihlawulweyo lubalulekile kulawulo lokwaziswa kwakhona olunolwazi. Abantu abadala abalishumi elinesithandathu (5♂11♀) baphinde baziswa ukusuka eJiangsu Dafeng Milu National Nature Reserve ukuya eHunan East Dongting Lake National Nature Reserve ngoFebruwari 28, 2016, apho abantu abayi-11 baseMilu (1♂10♀) bebenxibe iGPS yokulandela umkhondo. iikhola. Emva koko, ngoncedo lwetekhnoloji ye-collar ye-GPS, idibaniswe nokuqwalaselwa kokulandelwa komhlaba, silandele i-Milu ebuyiselweyo kunyaka omnye ukusuka ngo-Matshi 2016 ukuya kuFebruwari 2017. Sasebenzisa iModeli ye-Brownian Bridge Movement eguquguqukayo ukuqikelela uluhlu lwekhaya lomntu ngamnye kwi-10. rewilded Milu (1♂9♀, umntu obhinqileyo om-1 uye wasuswa ngenxa yokuba ikhola yakhe iwe) kunye noluhlu lwamaxesha onyaka amabhinqa ayi-5 eMilu (zonke zilandelelwa ukuya kutsho kunyaka omnye). Inqanaba le-95% limele uluhlu lwasekhaya, kwaye i-50% inqanaba limele iindawo eziphambili. Ukwahluka okwexeshana kwisalathiso esiqhelekileyo sokuhluka kwezityalo kwasetyenziselwa ukulinganisa utshintsho ekufumanekeni kokutya. Sikwalinganise usetyenziso lwemithombo yeMilu eyenziwe ngokutsha ngokubala umlinganiselo wokhetho kuzo zonke iindawo zokuhlala ezikwiindawo ezingundoqo. Iziphumo zabonisa ukuba: (1) isimbuku se-52,960 solungelelwaniso lolungiso lwaqokelelwa; (2) ngexesha lokuqala lokuguqulwa, umyinge wobungakanani bendlu ye-Milu ebuyisiwe yayiyi-17.62 ± 3.79 km.2kwaye umndilili weendawo ezingundoqo ube yi-0.77 ± 0.10 km2; (3) umyinge wonyaka wobungakanani bendlu yemazi yexhama yayingama-26.08 ± 5.21 km2kwaye umndilili wonyaka wemimandla engundoqo yayiyi-1.01 ± 0.14 km2kwinqanaba lokuqala lokukhulelwa; (4) ngexesha lokuqala lokulungiswa kwakhona, uluhlu lwekhaya kunye neendawo eziphambili zeMilu ehlaziyiweyo zachaphazeleka kakhulu ngexesha lonyaka, kwaye umahluko phakathi kwehlobo nobusika wawubalulekile (uluhlu lwasekhaya: p = 0.003; iindawo eziphambili: p = 0.008) ; (5) uluhlu lwamakhaya kunye neendawo eziphambili zenyamakazi ye-female e-rewilded kwindawo yase-Dongting Lake ngamaxesha ahlukeneyo abonisa ukuhambelana okungalunganga kunye ne-NDVI (uluhlu lwasekhaya: p = 0.000; iindawo eziphambili: p = 0.003); (6) Uninzi lwamabhinqa aphinde alahlwa uMilu abonise ukukhetha okuphezulu kwifama kuwo onke amaxesha onyaka ngaphandle kwasebusika, xa egxile ekusebenziseni ichibi nolwandle. Uluhlu lwekhaya leMilu ephinde yaphinda yasetyenziswa kwindawo yaseDongting Lake kwinqanaba lokuqala lokulungiswa kwakhona lafumana utshintsho olukhulu lonyaka. Uphononongo lwethu lubonisa umahluko wexesha lonyaka kuluhlu lwasekhaya lweMilu ehlaziyiweyo kunye nezicwangciso zokusebenzisa izixhobo zeMilu nganye ekuphenduleni utshintsho lonyaka. Ekugqibeleni, sibeka phambili ezi ngcebiso zolawulo zilandelayo: (1) ukuseka iziqithi ezihlala izilwanyana; (2) ukuphumeza ulawulo ngokubambisana koluntu; (3) ukunciphisa ukuphazamiseka kwabantu; (4) ukomeleza ukubekw'esweni kwabemi ukuze kuqulunqwe izicwangciso zolondolozo lweentlobo.
