Ubwoko (Inyamaswa):Milu (Elaphurus davidianus)
Ikinyamakuru:Urusobe rw'ibinyabuzima n'ibidukikije ku isi
Incamake:
Inyigo ku ikoreshwa ry’inyamaswa zo mu gasozi zongeye gushya mu rugo ni ingenzi mu gucunga neza inyamaswa zo mu gasozi zongeye gushya mu rugo. Inyamaswa 16 zo mu bwoko bwa Milu (5♂11♀) zoherejwe mu Kigo cy’Igihugu cy’Ubutaka cya Jiangsu Dafeng Milu zijyanwa mu Kigo cy’Igihugu cy’Ubutaka cya Hunan East Dongting ku ya 28 Gashyantare 2016, muri zo 11 zo mu bwoko bwa Milu (1♂10♀) zari zambaye imishumi yo gukurikirana GPS. Nyuma yaho, twifashishije ikoranabuhanga rya GPS collar, hamwe n’ibyo twakurikiranye ku butaka, twakurikiranye Milu yongeye gushya mu gihe cy’umwaka umwe kuva muri Werurwe 2016 kugeza Gashyantare 2017. Twakoresheje uburyo bwa dynamic Brownian Bridge Movement Model kugira ngo tumenye imiterere y’inyamaswa zo mu bwoko bwa Milu 10 zongeye gushya mu rugo (1♂9♀, inyamaswa 1 y’ingore yakuweho kubera ko ijosi ryayo ryaguye) n’imiterere y’inyamaswa zo mu bwoko bwa Milu 5 zongeye gushya mu rugo (zose zakurikiranywe kugeza ku mwaka umwe). Urwego rwa 95% rwahagarariye imiterere y’inyamaswa zo mu rugo, naho urwego rwa 50% ruhagarariye imiterere y’inyamaswa zo mu bwoko bwa Milu ... Ihindagurika ry'igihe mu gipimo cy'itandukaniro ry'ibimera ryakoreshejwe kugira ngo harebwe impinduka mu kuboneka kw'ibiribwa. Twanapimye ikoreshwa ry'umutungo wa Milu yongerewe inyamaswa mu kubara igipimo cyo guhitamo inyamaswa zose ziri mu duce twazo tw'ingenzi. Ibisubizo byagaragaje ko: (1) hakusanyijwe amoko 52.960 y'inyamaswa zometseho; (2) mu ntangiriro zo kongera inyamaswa zometseho ...2kandi ingano y'ubuso bw'ibanze yari 0.77 ± 0.10 km2(3) ingano y'impala y'ingore mu rugo ku mwaka yari 26.08 ± 5.21 km2kandi impuzandengo y'ubuso bw'ibanze ku mwaka yari 1.01 ± 0.14 km2mu ntangiriro zo kongera gutera inyamaswa; (4) mu ntangiriro zo kongera gutera inyamaswa, ahantu ho gutura n'ahantu ho hagati ya Milu yo mu bwoko bwa resorbed hagizweho ingaruka zikomeye n'ibihe by'izuba, kandi itandukaniro riri hagati y'impeshyi n'itumba ryari rinini (aho gutura: p = 0.003; ahantu ho hagati: p = 0.008); (5) ahantu ho gutura n'aho hagati y'impongo z'ingore zo mu bwoko bwa resorbed mu gace k'ikiyaga cya Dongting mu bihe bitandukanye byagaragaje isano iri hagati ya NDVI (aho gutura: p = 0.000; ahantu ho hagati: p = 0.003); (6) Imbogo nyinshi zo mu bwoko bwa Milu zo mu bwoko bwa resorbed zagaragaje ko zikunda cyane ubutaka bwo mu mirima mu bihe byose uretse mu gihe cy'itumba, igihe zibandaga ku gukoresha ikiyaga n'inkombe. Aho gutura kwa Milu yo mu bwoko bwa resorbed mu gace k'ikiyaga cya Dongting mu ntangiriro zo kongera gutera inyamaswa habayeho impinduka zikomeye mu bihe by'izuba. Ubushakashatsi bwacu bwagaragaje itandukaniro ry'ibihe mu bihe by'aho gutura kwa Milu yo mu bwoko bwa resorbed n'ingamba zo gukoresha umutungo za Milu imwe imwe mu rwego rwo guhangana n'impinduka z'ibihe. Amaherezo, twatanze inama zikurikira zo gucunga: (1) gushyiraho ibirwa byo guturamo; (2) gushyira mu bikorwa imicungire rusange y’abaturage; (3) kugabanya ihungabana ry’abantu; (4) gushimangira ikurikiranwa ry’abaturage mu gushyiraho gahunda zo kubungabunga amoko y’inyamaswa.
