Tekinoloje Yotsatira Imathandiza Kulemba Kusamuka Koyamba Kwa Ana a Whimbrel Osayimitsa Kuchokera ku Iceland kupita ku West Africa

Mu sayansi ya mbalame, kusamuka kwakutali kwa mbalame zazing'ono kwakhalabe gawo lovuta la kafukufuku. Tengani Whimbrel ya Eurasian (Numenius phaeopus), Mwachitsanzo. Ngakhale asayansi atsata mozama momwe amasamuka padziko lonse lapansi kwa ma whimbrel akuluakulu, akusonkhanitsa zambiri, chidziwitso chokhudza ana chakhala chosowa kwambiri.

Kafukufuku wam'mbuyomu awonetsa kuti ma whimbrel akuluakulu amawonetsa njira zosiyanasiyana zosamukira munthawi yoswana mu Epulo ndi Meyi akamayenda kuchokera kumalo osungiramo nyengo yozizira kupita kumalo omwe amaswana. Ena amawulukira mwachindunji ku Iceland, pomwe ena amadula ulendo wawo m'magawo awiri ndikuima. Pambuyo pake, kuyambira chakumapeto kwa July mpaka August, ma whimbrel akuluakulu ambiri amawulukira molunjika kumalo awo ozizira ku West Africa. Komabe, zidziwitso zovuta zokhudzana ndi ana, monga njira zomwe amasamuka komanso nthawi yake, sizinadziwikebe, makamaka pa kusamuka kwawo koyamba.

Pakafukufuku waposachedwa, gulu lofufuza ku Iceland linagwiritsa ntchito zida ziwiri zopepuka zotsatirira zomwe zidapangidwa ndi Global Messenger, mitundu ya HQBG0804 (4.5g) ndi HQBG1206 (6g), kuyang'anira ma whimbrel 13 achichepere. Zotsatirazo zinavumbula kufanana kochititsa chidwi ndi kusiyana pakati pa ma whimbrel achichepere ndi achikulire pamene anasamukira ku West Africa.

Mofanana ndi achikulire, ana ang’onoang’ono ang’onoang’ono ankauluka mosaimaima kuchoka ku Iceland kupita ku West Africa. Komabe, kusiyana kosiyana kunawonedwanso. Ana aang'ono amayamba nthawi yayitali kuposa akuluakulu ndipo sankatsatira njira yolunjika yosamukira. M’malo mwake, anaima kaŵirikaŵiri m’njira ndipo anauluka mwapang’onopang’ono. Tithokoze chifukwa cha ofufuza a Global Messenger, gulu la Icelandic linalanda, kwa nthawi yoyamba, ulendo wosayimitsa wa ana ang'onoang'ono osamuka kuchokera ku Iceland kupita ku West Africa, zomwe zimapereka chidziwitso chamtengo wapatali chomvetsetsa khalidwe la ana osamuka.

Chithunzi: Kuyerekeza kwamayendedwe owuluka pakati pa ma whimbrel akulu ndi achichepere aku Eurasian. gulu a. ma whimbrels akuluakulu, gulu b. Achinyamata.
