Le amabhere badle? Ngaba amabhere ukudla penguins?

Polar (okanye amhlophe) bear - esanyisayo ezidla ukubayinxalenye kusapho zeBhere. Ursus maritimus - igama layo Latin. Apho ke abudlayo, udla ibhere elimhlophe? Njengoko iphindaphindeka kunye basebenzisane kunye nezinye izilwanyana? Yintoni labantu bayo? Apho isilwanyana eso sihlala phi? Ngale kamva kweli nqaku.

imvelaphi

Ekuqaleni ndandicinga ukuba ukwahlulwa ibhere amfusa, namhlophe ntoni malunga 45-150 namawaka. Kwiminyaka eyadlulayo, mhlawumbi kwintsimi ahlala kuyo Ireland yanamhlanje. Kodwa izifundo yakutshanje kwafunyaniswa ukuba bahlukane kwenzeka malunga 338-934 namawaka. Kwiminyaka eyadlulayo. Malunga nekhulu, iminyaka engamakhulu amabini eyadlulayo kwakukho ziyazalana abameli iintlobo, nto leyo ekhokelele hybridization. Ngenxa yoko, zonke amabhere ukuba ahlale emhlabeni namhlanje inzala hybrids onesiphumo.

lweenkcukacha zangaphandle

Lebhere elimhlophe yenye ngabameli zinkulu ezanyisayo ezisentlabathini ezidla odolo. abantu Ukukhula ukufikelela neemitha ezi-3, ubunzima - up to a ton. Inkunzi eqhelekileyo, zalishumi ukusuka kg 400 ukuya 450, kwaye ubude bomzimba -. 250 ukuphakama igxalaba cm luphakathi 130 150 cm. Iimazi nobunzima kakhulu ngaphantsi - ukusuka 200 ukuya kg 300. Abameli zincinane bahlala Svalbard, kwaye ezinkulu - amanzi oLwandle wethu. Ezinye bear intloko emhlophe ezahlukeneyo caba nentamo ende. isikhumba umbala - omnyama. Uboya unokuba umbala ukusuka mthubi mhlophe (ehlotyeni "inoboya" ukuze abe tyheli ngenxa yendlela eyaboniswa rhoqo elangeni ngqo). Kwaneenwele ezi ezibuhlazarha, noboya ngokwayo akanalo kudala. kwaneenwele bukhanye ekwaziyo yokudlulisela yelanga eyingozi, apho inshorensi uzuza iipropati ubushushu. Ekwenzeni lebhere elimhlophe UV-zokudubula ukuze babonakale mnyama kwaye ngamanye amaxesha kunye 'ukuya green "ewe. Oku kwenzeka xa kukho ibhere kumhlophe zoo, kwimozulu eshushu. Ngenxa kubume ekhethekileyo kweenwele kuzo Luhlala ulwelwe obungabonakaliyo - yiyo zitshabalale eluhlaza. Ukuze ukuba ngumkhenkce kwaye andahexa kwi ngumkhenkce, ekuncothukeni kweentende zeenyawo yonke imilenze yeni iinwele. Phakathi kweminwe palama ibekwe kwi ihamba phambi ezifumaneka langoku abantamo. Kamva kweli nqaku inkcukacha malunga ukutya amabhere.

impilo

amabhere bahlala ice floes fast iyalandela. Apho, baya kuzingelwa kwaye geni ukutya zazo eziphambili. Le amabhere badle? ukutya engundoqo nomvundla (elwandle), itywina engqongwe, isilo solwandle esinamabamba amade kunye nezinye izilwanyana zasemanzini. ixhoba layo abambe, ukweqa ukuya ngasemva kwiphepha okanye kufutshane emithonjeni. Kufuneka ususe ixhoba ukusuka entloko emanzini, ngathi paw isilwanyana amnqande naye notsalo elunxwemeni. ibhere elimhlophe kwakhona yokuchitha floe ice apho kuhlala amatywina. Bazingela isilo solwandle esinamabamba amade kuqhutywa kuphela emhlabeni. Ngokuqhelekileyo, yena watya amanqatha kunye nesikhumba. Kwimeko yindlala kakhulu zayidla yonke isidumbu a isilo solwandle esinamabamba amade. Kodwa ngokuqhelekileyo iintsalela isilwanyana wambamba koko utya iimpungutye. Kodwa oku zonke zitya amabhere. Xa ungakwazi sithathe amabunzi, amantshontsho abafileyo, intlanzi, amaqanda. Kwakhona kwizidlo ibandakanya ulwelwe kunye nengca. Ukuba amabhere abonakale kwiindawo zabantu abambalwa, ngoko ungabona nabo doti, Akukude kwiinda endlu kunye nokutya inkunkuma. Kukho iimeko nkqu yeevenkile ukuphanga yegrosari emsebenzini ezibandayo. Yonke into zitya amabhere, igalelo sokuzuza osesibindini ivithamin A. Lo compound ekhoyo emizimbeni yabo kukuninzi ngokwaneleyo. Kukho ulwazi malunga kwiimeko ezininzi zesibindi letyhefu. Ngaba amabhere ukudla penguins? Le Mboniselo angenzeka abo akazazi yemvelo yezi zilwanyana. Yinto eyaziwayo ukuba yoonombombiya bemi baseMzantsi Afrika kunye amabhere - i-North Pole. Phantsi kweemeko zendalo, ukuba ukuhlangana ukuba abakwazi. Ngaphezu sele waxelelwa ukuba ukutya amabhere. Kunye abameli South Pole ayifakwanga phakathi ukutya kwabo.

yokufuduka

Ngokutsho utshintsho ngonyaka kwi imida Imikhenkce ekumiselwe kuyo incam yezwe, amabhere ukwenza utshintsho ngamaxesha athile. Ehlotyeni, baya kuwa kufutshane umva kwipali ebusika - abeza kweli mmandla osemazantsi, ukuya nezwe. Ngaphandle kwento yokuba amabhere kaninzi baqhubeka kulengqele nemida, baye kulala phantsi emhadini kwiziqithi okanye mpumalanga, kwezinye iimeko, malunga amahlanu yeekhilomitha ukusuka elwandle. Silele, ubude leyo yahluka ukusuka kwiintsuku ezingama-50 ukuya 80, ebonakala zidla nabasetyhini abakhulelweyo. Abangenawo samochki kunye namadoda azenzeki nyaka ngamnye, yaye isithuba olude elifutshane ixesha.

ukuziphatha

Nangona emuncu xa uqala kuqala, ukungakhululeki, amabhere kuphekeka nimble, nkqu phezu komhlaba. Xa amanzi, ukuba ukungena lizokudada kakhulu lula. Ukusuka manzi nengqele emzimbeni ibhere kwamanzi likhuselwe nonwele exineneyo obukhulu kakhulu. umsebenzi olulodwa encomekayo lwenziwa yi ongama namanqatha umaleko kangange elishumi. Usuke kunokuba inkomo negalelo umbala ukukhanya kwayo. amabhere ukuba ziphuhliswe kakuhle gqitha ukuva, ukubona kunye nevumba. ixhoba, ukuba sele ukubona kwiikhilomitha ezimbalwa, kunye, umzekelo, kengoku itywina weemitha 800.

buphindwe

Ghosn luqala amabhere ngoMatshi yaye uphela ngoJuni. Le estrus kowesi- idla kulandele amadoda amathathu okanye amane. Ngo-Oktobha, elilithokazi uqale ukutsala iidipozithi emhadini. Ivelisa babe kwiindawo ozithandayo apho zibuthe (of. Wrangel, umzekelo). qho ngonyaka kwiindawo ezinjalo, kukho malunga 150-200 imingxunya. Imigongxo bhere izinziswe kuphela phakathi kuNovemba, ekupheleni kweqonga abagxothwa iintsana yokumitha. Yonke Pregnancy ihlala imihla 230-250. Ekupheleni okanye phakathi amathole yasebusika ibhere Arctic bazalwa. Imazi efanayo kakhulu, kunjalo, uhlala nbuleleyo de Apreli. Kufuneka ke ukuba weebhere kuba amandla okuzala ephantsi. Inzala lokuqala ubonakala kwiminyaka 4-8. Okuzala zenzeka rhoqo emva kweminyaka emibini ukuya kwemithathu, kwenye inkunkuma ematholeni enye ukuya kwezintathu. Ngenxa yoko, elilithokazi ebomini uvelisa nangekho ngaphezulu kweshumi okanye elinesihlanu abaselula. Kubelekwa babe ubunzima ukusuka grams 450 ukuya 750. Emva kweenyanga ezintathu kunye nabo imazi ishiya emhadini aqalise ezula ubomi. Elinesibhozo ukuhlala oselula nonina. Ngeli xesha, zayidla amathole ubisi.

isakhiwo social

Kufuneka ke ukuba izinga lokusweleka phakathi esencinane 10-30%. Ubude wobomi alinazo ngaphezulu 25-30 iminyaka, ingxelo ixesha elide ekuthinjweni - iminyaka emashumi mane anesihlanu. Njengomthetho jikelele, izilwanyana seluxolweni ngokuphathelele kumalungu yohlobo lwazo. Kodwa ngexesha lokuzala zingenzeka ukungqubana phakathi into eyindoda. Ngamanye amaxesha nhloko kuhlasela abaselula, ikakhulu eyindoda. amabhere kungabangela kunye omdaka. Isiphumo lithiwe (ukukhwelwa) inzala - Grizzly polar.

Isimo yabantu kunye nexabiso loqoqosho

Lebhere elimhlophe idweliswe kwi-Red encwadini Russian Federation njenge neentlobo ezinqabileyo. Ngenxa yokufa impahla esencinane kunye olukhutshelweyo kade lesi silwanyana kuba lula ngokwaneleyo abasemngciphekweni. Kodwa nangona oku, abantu ngoku ingqalelo izinzile, zize zibe nzima ngandlela ithile. I Inuit omilenze amabhere ukuba inyama ifihla. In Russia lakuphelisa nokuzingelwa kwezilwanyana ukususela 1956. Kwamanye amazwe (eGreenland, Canada kunye ne-USA) nezokukhupha lebhere elimhlophe ulinganiselwe. ERashiya namhlanje, kukho malunga 5-7 amawaka abantu. Kule abangenamvume zokudubula malunga 150-200 amabhere ngonyaka.
