Mitundu (ya mbalame):Kreni Yokhala ndi Hooded (Grus monacha)

Chidule:

Kreni ya Hooded Crane (Grus monacha) yalembedwa ngati mtundu wa mbalame zomwe zili pachiwopsezo ndi IUCN. Chidziwitso chokhudza kusamuka kwa Kreni ya Hooded chikadali chochepa. Pano tanena za kusamuka kwa malo ndi nthawi kwa Kreni ya Hooded Crane m'nyengo yozizira ku Izumi, Japan, komanso malo ofunikira oti azisungire. Kreni zinayi zazikulu ndi zisanu zazing'ono, zonse m'nyengo yozizira ku Izumi, Japan, zidayikidwa ma transmitter a satellite (GPS-GSM system) pamalo awo oimapo kumpoto chakum'mawa kwa China mu 2014 ndi 2015. Tasanthula nthawi ndi nthawi ya akuluakulu ndi zazing'ono m'nyengo yopuma ya masika ndi autumn, komanso nthawi ndi nthawi yomwe adakhala pamalo oberekera ndi opuma. Kuphatikiza apo, tasanthula momwe ma kreni amagwiritsidwira ntchito m'malo opumapo. Kreni zazikulu zimatenga nthawi yayitali kuti zisamukire kumpoto m'nyengo yozizira (avereji = masiku 44.3) ndi kum'mwera m'dzinja (avereji = masiku 54.0) poyerekeza ndi kreni zazing'ono (masiku 15.3 ndi 5.2, motsatana). Komabe, mbalame zazing'ono zomwe zinali ndi nthawi yayitali yozizira (avereji = masiku 149.8) ndi nyengo yoyendayenda (nyengo yoberekera akuluakulu) (avereji = masiku 196.8) poyerekeza ndi zazikulu (masiku 133.8 ndi 122.3, motsatana). Malo atatu ofunikira oimapo apezeka: dera lozungulira Muraviovka Park ku Russia, Songnen Plain ku China, ndi gombe lakumadzulo kwa South Korea, komwe ma cranes ankathera nthawi yawo yambiri yosamukira (62.2 ndi 85.7% nthawi ya masika ndi nthawi yophukira, motsatana). Panthawi yosamukira, nthawi yoyendayenda komanso nthawi yozizira, ma Hooded Cranes nthawi zambiri amakhala m'malo olima kuti apumule ndi kudyetsa. M'nyengo yosakhala yozizira, malo ochepera 6% oimapo anali m'malo otetezedwa. Ponseponse, zotsatira zathu zimathandiza kumvetsetsa momwe ma Hooded Cranes amasamukira m'malo osiyanasiyana chaka chilichonse, komanso kukonzekera njira zosungira mitundu iyi.
