Amaqiniso ethakazelisayo amabhere: incazelo kanye izici

Ngokungangabazeki, amabhere ezinye izilwane ezimangalisayo kakhulu kakhulu owake ayezulazula kule planethi. Ukuze iqiniso nje ukuthi lezi zilwane ezimangalisayo uphathe siqhubeke siphila ezimweni ezimbi kakhulu zezulu, zingabantu nobabazekayo. amabhere - Abantu abahlukumeza abanye zingenakunqobeka, kodwa kungaba kwabaphoqelela cute, bonisa ubuhlakani obukhulu nokumangala kaningi. Sikumema ukuba ufunde amaqiniso ethakazelisayo amabhere izingane kanye nabantu abadala ukubona lezi zilwane ngobubona ukukhanya okusha!

Yemvelo amatilosi Born

Amaqiniso ethakazelisayo amabhere usitshele ukuthi nakuba lezi zilwane engazalwa umhlaba, bachitha ingxenye enkulu isikhathi asichitha ehamba olwandle. Shono igama yesayensi yabo Ursus maritimus kuzwakala futhi lisho "ulwandle bear". Lezi zilwane ezinamandla - kukhona ababhukudi esihle, bakwazi ukudlulisa okwenzeke esikhathini amanzi ibanga km kuka 100 uhambe izinsuku eside. Kulokhu Basizwa unyawo ezinkulu (ububanzi 30 cm), zisebenza njenge Izigwedlo.

amabhere letingabhukusha ngesivinini 10 km / h, okuyinto cishe kabili okushesha njengokungena Amaqhawe odumile we mncintiswano. Olympic semiphumela 6 km / h. Nokho, lokhu kwakungenele ukubamba seal amanzi evulekile. Ngakho-ke athwale ukhetha isicupho isizinda on eqinile, okuyinto has inzuzo isivinini nokushesha.

On izwe White Bear ukhetha ukuhambisa Ukulula izinyawo cishe 5 km / h. Kodwa lokhu umhlaseli akakwazi ngokuthi kancane: lapho afuna Ingasheshisa-40 km / h.

Kodwa lokho akuyona yonke amaqiniso ethakazelisayo namabhere. Qhubekela phambili.

Akuvamile, kodwa ngobunono

Nge inhlanhla, amabhere ngokuvamile abambe isilwane asizingelayo zonke izinsuku kuya kwemihlanu. Uma inhlanhla kuyasuka nomzingeli umzimba izenzo zakhe amanoni + njengephunga isipele isitoreji amandla uhlelo. expanses Iqhwa ye-Arctic akakwazi ngokuthi ngezizathu ukuzingela ocebile. Kodwa ukuthola bear isisulu kusiza ekhaleni mncane. Isilo kungaba iphunga uphawu, waphuma kwi iqhwa for 20-30 km.

abantu abayishumi

Ufuna ukwazi amaqiniso athakazelisayo kabanzi mayelana polar bear? Lokhu izilwane polar - ezweni nomzingeli ngobukhulu emhlabeni. Akazi nakwazi babe izitha zemvelo. Futhi akumangalisi: iduna omdala, ayehlome amazinyo abukhali futhi izimpiko, ngokuvamile anesisindo esingamakhilogremu kusuka 351 kuya 544 kg, okuhambelana isisindo sabantu 5-7.

Kodwa kukhona imidondoshiya yangempela. Elikhulu kunawo wonke ake alotshwa amabhere owayehlala ntshonalanga Alaska ngo-1960, enesisindo esingaba 1000 kg!

Abesilisa ukufinyelela usayizi zabo esiphezulu ngesikhathi kweminyaka engu 8 kuya ku-14 ubudala, kanti insikazi - eminyakeni 5-6. Kwakamuva nesisindo isigamu Cavaliers zabo - kuze kufinyelele 290 kg.

Ukukhulelwa ngoba kamuva

inqubo Amazing eziphilayo okwaziwayo njengoba yenzeka imisiwe, ihlinzeka polar bear amawundlu owazalwa esihle kunazo zonke onyakeni lapho amathuba abo okusinda kukhona enkulu. Yokukhwelana lezi zilwane ivela Apreli May, kodwa ukuthuthukiswa zemibungu is braked ngendlela efanele usaqala futhi uyaqhubeka iwe kuphela uma owesifazane sithathe isisindo ngokwanele futhi uzolunga ilungiselelo womgodi ebusika.

Kodwa lokhu amaqiniso ethakazelisayo amabhere ungazange iphelile.

Usayizi wekati

amabhere akuvamile yokucashisa like izihlobo zabo ensundu. Okuhlukile izinsikazi ezimithi kuphela bephoqeleka ukwakha nasemihumeni, uzise isikhathi ngo-February-March. Phela, amawundlu azo, njengoba ezinye amabhere, bazalwa encane kakhulu futhi ungenamandla futhi zivikeleke ngaphansi kwezimo ezinzima e-Arctic. Kuyinto ukwazi ukuthi lapho kuzalwa ezweni izilwane ezidla ezinye ngobukhulu emhlabeni abe obuphelele umzimba-30 cm futhi inesisindo kuphela iphawundi, cishe like a ingulube Guinea.

Bear ngokuvamile uzozala pair of amawundlu. Nokho, kwenzeka lapho umntwana nje esisodwa noma ezintathu kubo.

Nakuba inzalo ungatholi namandla, ibhere uhlala emgodini esimweni basebusika: musa adle noma aphuze. Esikhathini esizayo, amawundlu ahlale nonina iminyaka engaba mibili, ngesikhathi lapho zifunda amakhono adingekayo ukuze usinde ngempumelelo e-Arctic nokhahlo.

eziseduze

Ngokuhamba kwesikhathi, sathola konke amaqiniso ezintsha nezithakazelisayo mayelana amabhere e-Arctic. Ngokwesibonelo, ngo-2006 kwi insimu yalesi sifunda kwatholakala isilo engavamile waphenduka polar bear nengxenye kuphela.

Izazi zezakhi zofuzo zithi polar bear kwaba ukuzehlukanisa njengoba oluthile amakhulu ezinkulungwane edlule. Lokhu kuboniswa izifundo ezifanele. Kodwa, naphezu kwalokhu, kwatholakala ukuthi amabhere bayakwazi ukuqalisa inzalo ezikanye amabhere ansundu. Ngaphezu kwalokho, kuyoba inzalo evundile, ngokungafani nenye inzalo ka beyizalaniselana (isb, iminyuzi). nzalo ezinjalo ziyavela kokubili endle futhi ekuthunjweni, kodwa kakhulu kuyaqabukela.

Isilwane okuqala, yazalwa ngo endle, futhi kwatholakala ngo-2006. Nokho, ngaleso sikhathi, ososayensi kakade kwadingeka ithuba abantu bambuke bemangele njengesilwane basekuthunjweni, zoo emzini Osnabrück eJalimane, lapho amabhere nsundu abahlala endaweni ebiyelwe efanayo. Kusukela ngomhla ka-2010 kwakwaziwa kakade amabhere hybrid mayelana 17. Futhi ngo-2012, kwakunabamemezeli imibiko emihlanu evela kubantu abathi we nzalo ezinjalo endle.

amabhere Black polar

amabhere zibonakala zimhlophe, kodwa, njengoba isaga sithi, ukuvela bungakhohlisa. athwale noboya (okuthiwa unogada izinwele) kanye undercoat yayo empeleni cishe esobala. Kodwa iqiniso liwukuthi ngaphakathi ngamunye elingenamikhono phezulu has umgodi nomoya. Ngenxa lesi sakhiwo esiyinkimbinkimbi anoma yibuphi ubude amaza okukhanya kubonakala kusukela izinwele kahle. Ngenxa yalokho, i-polar bear ubukeka emhlophe.

Nokho, kuye ngokuthi inkathi kanye ekhomba lapho ilanga lingakhona izilwane angabukeka aphuzi noma ensundu. Ngezinye izikhathi, ngenxa yesimo sezulu ngokungavamile efudumele, linombhalo ngisho luhlaza ngenxa ulwelwe, bazinza uvolo yabo.
