Asayansi atchula mbalame yomwe imatha kuuluka makilomita oposa 11 popanda kupuma
Anthu ambiri kamodzi m'miyoyo yawo amalota kukhala ndi mapiko, koma mbalame sizingokhala ndi gawo ili la thupi, komanso zimatha kuuluka kwa nthawi yaitali, zina mwazo popanda kuyimitsa, chakudya ndi madzi.
Mbalame zili ndi mphamvu zamphamvu zomwe anthu amangozilota - zimatha kuwuluka. Kutha kuuluka kumatanthauza kuyenda mwachangu, ndipo mbalame zina, monga atsekwe, zimadziwika kuti zimasamuka mpaka makilomita 2,400 m'maola 24, analemba Grunge.
Izi ndi zochititsa chidwi, koma pali mbalame zomwe zimapita kutali kwambiri. Mwachitsanzo, mbalame yaing’ono ya m’mphepete mwa nyanja, yotchedwa bartail godwit, yokhala ndi mlomo wautali modabwitsa, ndiyo inauluka kwautali kwambiri kuposa ina iliyonse imene asayansi alembapo.
Malinga ndi akatswiri, godwit amatha kugonjetsa makilomita oposa 11 zikwi popanda kuyimitsa. Chochititsa chidwi kwambiri n’chakuti mbalamezi zimauluka mothamanga kwambiri, kutanthauza kuti mapiko awo amakhala akuyendayenda panthawi yonse imene akuuluka, mosiyana ndi mbalame za albatross.

Akatswiri akhala akutsatira mbalamezi kuyambira 2007 ndipo adapeza kuti nthawi zonse zimabisala mpaka 11 km.
Mitundu ina ya godwit imadziwika kuti imayenda kuchokera ku Australia kupita ku New Siberia, pomwe ina imasamuka ku New Zealand kupita ku Alaska.
Akatswiri akhala akutsatira mbalamezi kuyambira 2007 ndipo adapeza kuti nthawi zonse zimadutsa makilomita 11,000. M’ngululu, mbalame za m’mphepete mwa nyanja zimenezi zimapezeka m’mphepete mwa nyanja yachonde, kumene zimapeza chakudya chambiri pakati pa magombe ndi madambo. Amayikiranso mazira mu zisa zaudzu nthawi ya masika.
Mu June kapena July amayamba ulendo wawo wautali wobwerera kwawo, kumene ena amaima ku America kapena kumpoto kwa Africa kuti adye. Ena samayima nkomwe, amakhala masiku 8 paulendo wa pandege popanda kupuma.
Chinsinsi cha Godwit
Godwit ali ndi njira yosiyana yosungira ndi kutaya mafuta kuposa zolengedwa zina zambiri.
Mofanana ndi mbalame zambiri zomwe zimakonda kusamukasamuka, mbalame za godwit zili ndi luso lodabwitsa lomwe zimawathandiza kuyenda m’derali. Kuti mbalame zizitha kuyenda maulendo ataliatali ngati amenewa, zimafunika kudziwa bwino nthawi, kudziwa nthawi, mtunda, komanso kuneneratu za nyengo. Koma chofunika kwambiri chimene ayenera kuchita asananyamuke n’kudzola mafuta okwanira kuti azitha kuyenda ulendo wautali.
Ndikofunika kuzindikira kuti mbalame za godwit zili ndi njira zosiyana zosungira ndi kutaya mafuta kusiyana ndi zolengedwa zina zambiri. Pamene thupi la mbalamezi limatentha mafuta, limapanganso mpweya woipa ndi madzi, zomwe zimasungidwa m'mafuta. “Mphamvu” imeneyi imawathandiza kukhalabe ndi moyo osamwa madzi kwa masiku angapo.
Osati popanda biology
Matupi a Godwitches ndi mapiko ake ndi aaerodynamic, ndipo kupuma kwawo kumawathandiza kukhala ndi moyo ndi mpweya wochepa.
Matupi a Godwitches ndi mapiko ake amakhala ndi mphamvu youluka, ndipo mpweya wawo umawathandiza kuti azitha kukhala ndi moyo ndi mpweya wochepa kwambiri akamauluka pamwamba pa nyanja, kumene mpweya wa okosijeni uli wocheperapo kusiyana ndi pamtunda.
Kafukufuku wa asayansi akusonyeza kuti asanayambe kuuluka, minofu ya pachifuwa, mtima, ndi mapapo kuwirikiza kawiri kapena katatu kukula kwake, pamene m’mimba, chiwindi, matumbo, ndi impso zimachepa kukula kwake. Kusintha kumeneku kumabwerera mwakale mbalamezi zikafika kumene zikupita.
Komanso, zolengedwa zodabwitsazi zili ndi luso lina lomwe anthu ambiri angakonde kukhala nalo - amatha kugona panthawi yaulendo.
Izi zili choncho chifukwa ubongo wawo ndi wa unihemispheric, zomwe zimawathandiza kuti azigona mopanda REM. Izi zikutanthauza kuti mbali imodzi ya ubongo wawo ili mtulo pamene ina ili maso mpaka kukafika kumene akupita.
