O Chimbalangondo Choyera kapena nyanja zam'madzi, yemwenso amadziwika kuti Polar Bear, ndi nyama zolusa kwambiri ku Arctic. Ndi nyama yodya nyama ya chimbalangondo ndipo, mosakayikira, ndi nyama yayikulu kwambiri padziko lonse lapansi.

Ngakhale amasiyana mosiyana ndi chimbalangondo chofiirira, chowonadi ndichakuti amagawana zikhalidwe zazikulu zomwe zingalolere, mwa kungoganiza, kubereka ndi ana achonde a mitundu yonse iwiri. Ngakhale zili choncho, tiyenera kutsindika kuti ndi mitundu yosiyana, chifukwa cha kusiyanasiyana kwamakhalidwe ndi kagayidwe kake ndi chikhalidwe cha anthu. Monga kholo la chimbalangondo choyera, timawonetsa Ursus Maritimus Tyrannus, subspecies yayikulu. Kuti mudziwe zambiri za nyama yabwinoyi, musaphonye pepala ili la Perito, komwe timakambirana za Makhalidwe a chimbalangondo ndipo timagawana zithunzi zodabwitsa.

kumene kumakhala chimbalangondo

O malo okhala ndi chimbalangondo ndizo zokometsera zosatha za madzi oundana, madzi oundana ozungulira madzi oundana, ndi zigwa zosweka za mashelufu oundana a Arctic. Pali anthu asanu ndi limodzi padziko lapansi omwe ali:

• Madera akumadzulo kwa Alaska ndi Wrangel Island, onse ndi a Russia.
• Kumpoto kwa Alaska.
• Ku Canada tikupeza 60% ya ziwerengero zonse za zimbalangondo zapadziko lonse lapansi.
• Greenland, Chigawo Chodziyimira ku Greenland.
• Zilumba za Svalbard, za ku Norway.
• Land of Francis Joseph kapena Fritjof Nansen zilumba, zomwe zilinso ku Russia.
• Siberia.

Makhalidwe a Polar Bear

Chimbalangondo cha kumalo ozizira, limodzi ndi chimbalangondo cha Kodiak, ndiye nyama zazikulu kwambiri pakati pa zimbalangondo. ngati mukufuna kudziwa Kodi chimbalangondo cha polar chimalemera motani, amuna kupitirira 500 kg kulemera, ngakhale pali malipoti a zitsanzo zolemera makilogalamu opitilira 1000, ndiye kuti, kuposa 1 ton. Akazi amalemera kupitirira theka la amuna, ndipo amatha kutalika kwa mita 2. Amuna amafika mamita 2.60.

Kapangidwe ka chimbalangondo chakumtunda, ngakhale chinali chachikulu kukula, ndi kocheperako poyerekeza ndi cha abale ake, zimbalangondo zofiirira ndi zakuda. Mutu wake ndi wocheperako ndipo umalumikizidwa kummero kuposa mitundu ina ya zimbalangondo. Kuphatikiza apo, ali ndi maso ang'onoang'ono, akuda komanso owala ngati ndege, komanso mphuno yolimba yomwe ili ndi mphamvu yayikulu kwambiri. makutu ndi ang'ono, waubweya komanso wozungulira kwambiri. Kusintha kwa nkhope kumeneku kumachitika chifukwa cha zolinga ziwiri: kubisa komanso kuthekera kupewa kupewa kutentha kwa thupi kudzera m'ziwalo za nkhope.

Tithokoze chifukwa chovala chipale chofewa chomwe chimakwirira thupi lalikulu la chimbalangondo choyera, chimafanana ndi madzi oundana omwe amakhala, motero, madera omwe amasaka. chifukwa cha ichi kubisa kwabwino, imakwawa kudutsa pamadzi oundana kuti iyandikire pafupi ndi zotsekera zaminga, zomwe ndizomwe zimakonda kudya.

Kupitilira ndi mawonekedwe a chimbalangondo chakumtunda, titha kunena kuti pansi pa khungu, chimbalangondo choyera chimakhala ndi mafuta osanjikiza zomwe zimakutalikitsani bwino ndi ayezi komanso madzi ozizira owundana omwe mumayendamo, kusambira komanso kusaka. Miyendo ya chimbalangondo chakumaloko ndi yotukuka kwambiri kuposa ya zimbalangondo zina, chifukwa idasinthika ndikuyenda mamailosi ambiri pachisumbu chachikulu komanso kusambira mtunda wautali.

Kudyetsa chimbalangondo

Chimbalangondo choyera chimadyetsa makamaka zazitsanzo zazing'ono kuchokera zisindikizo zolimba, nyama zomwe zimasaka madzi oundana kapenanso m'madzi mwanjira yapadera.

chimbalangondo pali njira ziwiri zosakira: ndi thupi lake pafupi kwambiri, amayandikira kwambiri chisindikizo chotsalira pa ayezi, amadzuka modzidzimutsa ndipo atathamanga pang'ono, amaponya chigoba chowotcha mumutu wa chisindikizo, chomwe chimatha ndi kuluma. mu khosi. Mtundu wina wosakira, ndipo wofala kwambiri, umakhala pongoyang'ana pakatikati kazisindikizo. Mawotchi amenewa ndi mabowo omwe zisindikizo zimapanga mu ayezi kuti azizungulira ndikupuma popumira m'madzi okutidwa ndi ayezi. Chisindikizo chikatulutsa mphuno yake m'madzi kuti ipume, chimbalangondo chimamenya mwankhanza chomwe chimaphwanya chigaza cha nyamayo. Amagwiritsanso ntchito njirayi ku kusaka belugas (asitikali am'madzi okhudzana ndi ma dolphin).

Zimbalangondo zam'madzi zimazindikiranso zisindikizo zobisika m'mabwalo omwe anakumbidwa pansi pa ayezi. Akapeza malo enieniwo pogwiritsa ntchito fungo lawo, amadziponyera ndi mphamvu zawo zonse padenga lachisanu la khola lomwe mwana wabisalapo, ndikugwera pamwamba pake. M'nyengo yachilimwe amasakanso mphalapala ndi caribou, kapena mbalame ndi mazira m'malo okhala ndi zisa.

Kuti mumve zambiri, musaphonye nkhaniyi pankhani yoti chimbalangondo chimapulumuka kuzizira.

Khalidwe la chimbalangondo

chimbalangondo sichitha monga anzawo a mitundu ina amachitira. Zimbalangondo zoyera zimadziunjikira mafuta m'nyengo yozizira ndikuzitaya nthawi yotentha kuti ziziziritse matupi awo. Nthawi yoswana, akazi samadya chakudya, kutaya theka la thupi lawo.

Ponena za Kuswana kwa chimbalangondo, pakati pa miyezi ya april ndipo mwina ndi nthawi yokhayo yomwe akazi amalekerera amuna, chifukwa cha kutentha kwawo. Kunja kwa nthawiyi, machitidwe pakati pa amuna ndi akazi siabwino. Zimbalangondo zamphongo zazimuna zimadya anzawo ndipo zimatha kudya ana kapena zimbalangondo zina.

Kuteteza Polar Bear

Tsoka ilo, chimbalangondo chakumtunda chili pachiwopsezo chachikulu chakutha chifukwa cha umunthu. Pambuyo pakusintha kwazaka zopitilira 4 miliyoni, pakadali pano akuti mwina zamoyozi zitha kutha pakatikati pa zaka za zana lino. Kuwonongeka kwa mafuta ndi kusintha kwa nyengo zikuwopseza kwambiri nyama zokongolazi, zomwe zimangodya mdani wawo ndi anthu.

Vuto lalikulu lomwe likukumana ndi chimbalangondo chakumtunda ndi zomwe zimayambitsa kusintha kwa nyengo m'chilengedwe chake. Kukula pang'ono pang'ono kwa kutentha m'nyanja ya Arctic kumayambitsa msanga thaw a madzi oundana a Arctic (dera lalikulu la ayezi woyandama) omwe amapanga malo osakira a chimbalangondo. Kuchepetsa msanga kumene kumapangitsa zimbalangondo kulephera kupanga malo ogulitsa omwe amafunikira kuti azitha kusintha nyengo ndi nyengo. Izi zimakhudza chonde cha mitunduyi, yomwe posachedwapa anatsika pafupifupi 15%.

Vuto lina ndi kuwonongeka kwa malo ake (makamaka mafuta), popeza kuti Arctic ndi dera lokhala ndi zinthu zoipitsa komanso zomalizirazo. Mavuto onsewa amatsogolera zimbalangondo kuti zigwere malo omwe anthu amakhala kuti azidya zinyalala zopangidwa ndi nzika zawo. Ndizomvetsa chisoni kuti kukhala wamkulu monga mdani wamkuluyu akukakamizidwa kupulumuka mwanjira imeneyi chifukwa chochita zovulaza zachilengedwe.

Zosangalatsa

• M'malo mwake, zimbalangondo zakumtunda alibe ubweya woyera. Ubweya wawo umakhala wowala, ndipo mawonekedwe owoneka bwino amawapangitsa kuti aziwoneka oyera ngati matalala nthawi yozizira komanso minyanga yambiri chilimwe. Tsitsi ili ndilopanda komanso lodzaza ndi mpweya mkati, womwe umatsimikizira kutenthetsa kwakukulu, koyenera kukhala munyengo yozizira ya Arctic.
• Ubweya wa chimbalangondowakuda, ndipo potero amalola bwino kutentha kwa dzuwa.
• Zimbalangondo zoyera sizimamwa madzi, chifukwa madzi omwe amakhala amakhala amchere komanso amchere. Amalandira madzi ofunikira m'magazi awo.
• Kutalika kwa moyo wa zimbalangondo zakumtunda kumakhala pakati pa zaka 30 ndi 40.
