Mitundu (ya mbalame):Whimbrels (Numenius phaeopus)

Chidule:

Malo oimikapo magalimoto ndi ofunikira kwambiri podzaza mafuta ndi kupumula mwa mbalame zosamuka. Kufotokozera bwino zofunikira za malo okhala mbalame zosamuka panthawi yoimikapo magalimoto n'kofunika kwambiri kuti timvetsetse za chilengedwe cha kusamuka komanso kusamalira zachilengedwe. Komabe, kugwiritsa ntchito malo okhala mbalame zosamuka pamalo oimikapo magalimoto sikunaphunziridwe mokwanira, ndipo kusiyana kwa malo okhala pakati pa mitundu sikunafufuzidwe kwenikweni. Tinatsata kayendedwe ka Whimbrels zosamuka, Numenius phaeopus, pogwiritsa ntchito ma tag a Global Positioning System–Global System for Mobile Communication ku Chongming Dongtan, malo ofunikira oimikapo magalimoto ku South Yellow Sea, China, mu masika 2016 komanso mu masika ndi autumn 2017. Kubwerera kwa zinthu zambiri ndi kuyerekeza kwa mitundu yosiyanasiyana kunagwiritsidwa ntchito kuti tizindikire zotsatira za mbalame iliyonse, diel factor (usana ndi usiku), ndi kutalika kwa mafunde pa momwe mbalame za Whimbrels zimagwiritsira ntchito malo okhala panthawi yoimikapo magalimoto. Mphamvu ya zochita za Whimbrels inali yotsika usiku kuposa masana, pomwe mtunda wapamwamba womwe unalembedwa kuti Whimbrels amasuntha unali wofanana pakati pa usana ndi usiku. Malo okhala ndi mchere ndi matope anagwiritsidwa ntchito kwambiri ndi mitundu yonse ya mbalame m'nyengo zonse zitatu: > 50% ndi 20% ya zolemba zonse zinapezeka kuchokera ku malo okhala ndi mchere ndi matope, motsatana. Kugwiritsa ntchito malo okhala kunali kosiyana kwambiri pakati pa mitundu yosiyanasiyana; minda ndi nkhalango zina zinagwiritsidwa ntchito ndi mitundu ina mu masika a 2016, pomwe malo obwezeretsa omwe ali pafupi ndi malo otsetsereka adagwiritsidwa ntchito ndi anthu ena mu 2017. Kawirikawiri, malo okhala ndi mchere, minda, ndi nkhalango ankagwiritsidwa ntchito kwambiri masana, pomwe malo okhala ndi matope ankagwiritsidwa ntchito kwambiri usiku. Pamene kutalika kwa mafunde kunakwera, kugwiritsa ntchito malo okhala ndi matope kunachepa pomwe kugwiritsa ntchito malo okhala ndi mchere kunawonjezeka. Zotsatira zake zikusonyeza kuti kutsatira zinthu zamoyo payekha kungapereke zambiri mwatsatanetsatane pakugwiritsa ntchito malo okhala masana ndi usiku. Kusiyana kwa momwe malo okhala pakati pa mitundu yosiyanasiyana ndi nthawi kumawonetsa kufunika kwa malo osiyanasiyana okhala kuti mbalame zisunge.
