Tus dais dawb lossis polar dais yog tsiaj muaj zog thiab zoo nkauj, yog lub cim tiag tiag ntawm Arctic. Txawm li cas los xij, cov neeg hauv paus txawm nyob rau sab qaum teb tau raug kev hem thawj. Tus naj npawb ntawm polar bears hauv Arctic tau poob qis heev nyob rau xyoo tas los no. Cov kws tshawb fawb hais tias hauv ib nrab xyoo pua lawv yuav tsis nyob hauv peb lub ntiaj teb txhua. Xyoo 2008, tus dais ncov qaum teb tau tshaj tawm tias muaj kev phom sij thiab muaj npe nyob rau hauv Phau Ntawv Liab.

Vim li cas ho muaj polar bears poob?

Cov kws tshawb fawb-zoologists muab ob peb lub laj thawj rau kev poob qis hauv cov pejxeem ntawm polar bears. Ntawm lawv yog tej yam ntuj tso thiab anthropogenic.

Ib qho ntawm cov laj thawj tseem ceeb vim li cas tus naj npawb ntawm cov polar bears txo qis tuaj yeem suav tias yog huab cua sov thiab qhov cuam tshuam txo qis hauv thaj tsam ntawm cov dej khov nab kuab. Thiab qhov no cuam tshuam rau lub neej ntawm polar dais, vim tias tus tsiaj nyaum no nyob los ntawm kev tua cov ntsaws ruaj ruaj. Tshaj li 30 xyoo dhau los, thaj tsam ntawm cov dej khov hauv Arctic Dej hiav txwv tau txo mus rau 5.02 lab square kilometers. km tawm tsam tus nqi nruab nrab ntawm ntau dua 7 lab square meters. km.

huab cua sov

Kev nyab xeeb hloov tau ua rau cov dej sov nyob rau yav qab teb Arctic hiav txwv. Qee cov ntses txias (piv txwv li, polar cod) tau tsiv mus rau thaj tsam sab qaum teb. Thiab tom qab lawv, cov pej xeem ntawm ringed ntsaws ruaj ruaj, uas polar bears yos hav zoov, kuj tsiv mus. Ib feem ntawm cov bears mus rau sab qaum teb ua raws li cov ntsaws ruaj ruaj, thiab cov seem yog ntsib teeb meem loj nrog zaub mov. Yog li ntawd, bears pib noj zaub mov uas tsis raug rau lawv - noog qe, lemmings, berries.

tsiaj tshaib plab tab tom tawm los rau tib neeg nyob. Hauv kev tshawb nrhiav zaub mov, lawv rummage los ntawm cov khib nyiab pov tseg thiab pov tseg, lawv ua rau muaj kev phom sij rau tib neeg. Cov tsiaj zoo li no raug tua, uas kuj piav qhia tias yog vim li cas tus nab npawb ntawm polar bears poob qis.

Tsis tas li, noj zaub mov pov tseg, lawv feem ntau nqos cov khoom phom sij xws li hnab yas, nylon nets rau zaub mov, daim iav, thiab raug tshuaj lom los ntawm cov khoom seem hauv tsev.

Kev ua neej

Tus tsiaj muaj zog thiab agile no ua rau lub neej taug kev. Thaum lub caij nplooj ntoos hlav, thaum cov dej khov pib yaj, polar bears txav mus rau sab qaum teb. Wandering los ntawm cov dej khov floe mus rau cov dej khov floe, lawv hloov mus ntev. Lawv dhia mus rau hauv dej khov thaum mus yos hav zoov lossis txav mus rau lwm qhov dej khov.

Huab cua sov tau ua rau cov dej khov ua rau nyias nyias thiab tsis muaj zog. Nws tawg yooj yim dua thiab crumbles ntawm kev cuam tshuam. Yog li ntawd, polar bears yuav tsum ua luam dej ntev dua li yav dhau los. Qhov no yog vim qhov loj loj pov tseg ntawm lub zog, thiab yog li zaub mov.nws yuav siv sij hawm ntau dua kom rov zoo. Cov me nyuam tsuas yog tsis muaj zog tshaj li kev taug kev thiab poob dej.

Vim cov dej khov hloov pauv, ntau tus menyuam dev tsis muaj sijhawm rov qab los rau hauv av los tsim. Ntau ntxiv, lawv raug yuam kom khawb cov pog koob yawg koob txoj cai ntawm cov dej khov floe, uas ua rau muaj kev pheej hmoo ntawm kev tuag rau ob tus menyuam mos thiab tus dais nws tus kheej. Tom qab tag nrho, qhov tsos ntawm cov menyuam yaus thiab pub rau lawv siv zog ntau heev los ntawm nws, thiab nws tsis tuaj yeem tawm hauv lub tsev mus yos hav zoov kom txog thaum cov menyuam tuaj yeem ua raws nws.

Yos Hav Zoov

Lwm qhov laj thawj yog vim li cas tus naj npawb ntawm polar bears poob qis yog kev nyiag. Thaum lawv yog cov khoom ntawm kev yos hav zoov nkaus xwb rau ob peb cov neeg hauv paus txawm nyob rau sab qaum teb, qhov no tsis pom. Tab sis thaum lawv pib tua dais nrog riam phom niaj hnub, siv lub nyoob hoom qav taub, tus naj npawb ntawm cov tsiaj tua tau nce ntau heev. Tag nrho cov kev ncig xyuas tau npaj los tua tus dais polar. Thiab daim tawv nqaij ntawm tus tua tsiaj Arctic tau ua rau pom zoo rau cov qhua.

Tam sim no tus dais ncov qaumteb qabteb muaj kev tiv thaiv, tab sis qhov no tsis yog kev cuam tshuam rau cov neeg yos hav zoov.

Kab mob

Cov kws tshawb fawb tab tom sim nrhiav kom paub meej tias yog vim li cas tus naj npawb ntawm cov kab mob polar txo qis. Cov lus teb txawv. Ntawm cov laj thawj tseem hu ua kab mob, xws li trichinosis. Nws yog tshwm sim los ntawm cov kab mob uas nyob hauv cov leeg ntawm cov tsiaj. Ntxiv nrog rau polar bears, arctic hma liab, sled aub, thiab cov ntsaws ruaj ruaj kuj raug kev txom nyem los ntawm nws. Ib txhia ntseeg tias tib neeg coj tus kab mob mus rau sab qaum teb.

Yuav tsis muaj qhov tsis ntseeg tias polar bears xav taukev tiv thaiv. Txwv tsis pub, peb cov xeeb leej xeeb ntxwv yuav tsis kawm txog tus tsiaj uas muaj zog thiab zoo nkauj zoo nkauj, tus nomad ntawm Arctic, uas nyob rau sab qaum teb hnyav.
