Ibhere elisendaweni emhlophe ingenye yezilwane ezimbalwa ezihlukaniswa zibe izinhlobo ezimbili ngasikhathi sinye. Ngakho-ke, emazweni amaningi, lesi silwane sihlukaniswa njengesilwane esincelisayo sasolwandle. Ngenkathi eCanada kubhekwa kuphela njengesilwane esincelisayo somhlaba. Awukho umbono owodwa lapha.
Kuze kube manje, ososayensi abakasunguli ngokungangabazeki ukuthi hlobo luni lwezimpande lolu hlobo lwesilwane olunalo. Ngokuya ngocwaningo oluningi, kungacatshangwa ukuthi ukhokho webhere elisendaweni emhlophe kuseyibhere elinsundu.
Okwamanje, kunezinhlobo ezingaphansi kwezingu-19 zalesi silwane, ezihlukaniswe ngamaqembu amane ajwayelekile.
Abesilisa abadala bakhulu impela - isisindo sabo sifinyelela kuma-350-600 kilograms. Ngokuqondene nabesifazane abadala, isisindo sabo sicishe sibe yingxenye - okungaphezu kwama-295 kilogram cishe akutholakali.
Ekilasini labo, amabhere we-polar abhekwa njenge-livers ende - endle, okungukuthi, endaweni yawo yemvelo, ahlala cishe iminyaka eyi-18-20. Kodwa-ke, abacwaningi babhale amacala amaningana lapho isilwane sihlala khona sineminyaka engama-30 ubudala. Ngokwehlukana, kufanele kushiwo ngalabo bantu abahlala ezimweni zokufakelwa - kulokhu, ibhere lingaphila iminyaka engaba ngu-40. Umgcini werekhodi nguDebbie the bear waseCanada, owaphila iminyaka engama-42, okungukuthi, okuphindwe kabili kunenani lalabo abahlala endle.
Lapho kuhlala khona
Lesi silwane esibabazekayo sihlala kuphela ezimweni ezikahle saso - e-Arctic. Lapho, uyanda, aqede ukudla kwakhe futhi akhe nemihume yeqhwa, lapho ahlala khona. Amabhere atholakala kulo lonke elase-Arctic, kepha iningi lawo lingatholakala ezindaweni lapho kunabantu abaningi bezimpawu zamaringe.
Lapha kungafaneleka ukuchaza ukutolika okungaqondakali kwesimo sengqondo ekilasini. Iqiniso ngukuthi lolu hlobo lwebhere elimhlophe luzivumelanise ngokuphelele nokuphila emhlabeni nasemanzini. Empeleni, ngakho-ke, abanye ososayensi bathi yimboni yasolwandle, kanti abanye bathi yizilwane ezincelisayo ezisemhlabeni.
Izilwane, yize zinamandla namandla okuzivumelanisa nezimo zezulu ezahlukahlukene, zisengozini enkulu ngokusinda. Ensimini yaseRussia, lezi zilwane zifakiwe kwiRed Book.
Ubuntu bebhere elimhlophe
Ngokumangazayo, kepha ibhere le-polar alibesabi abantu, kepha lokhu akusho ukuthi umuntu angaxhumana naye. Kuyafana, noma yini umuntu angayisho, kepha iyisilwane esidla ezinye. Iqiniso elithandekayo - kukhona ngisho "nejele" elikhethekile eCanada, lapho kuthathwa khona amabhere, asondele ezindaweni zokuhlala futhi abeka ingozi enkulu. Kuliqiniso, ngokubukeka kubukeka kufana ne-zoo futhi abaxabanayo bagcinwa lapho okwesikhashana.
Ngokuphathelene nezihlobo zabo, amabhere anokuthula, kepha ngesikhathi sokukhwelana angahlangana ndawonye nge-duel. Kuliqiniso, lokhu kudinga isizathu esibucayi - uma umphikisi engene endaweni yomunye umuntu futhi ethi ungowesifazane.
Ibhere elisendaweni emhlophe liseyisihambi leso - linganqoba kalula amabanga amafushane namade. Ngaphezu kwalokho, lokhu kungenziwa ngokubhukuda, nangokuhamba ezintabeni zeqhwa noma ngomhlaba nje.
Ukudla kwebhele elimhlophe
Ibhere le-polar polar liyisilwane se-tundra. Isisulu saso, njengomthetho, siba unogwaja wasolwandle, i-walrus, uphawu, uphawu. Umzingeli akabukeli phansi izinhlanzi ezinkulu, azibamba kalula.
Ukubalwa kwendawo lapho kudla khona inyamazane kwenziwa kanjena: ibhere limi ngemilenze yangemuva futhi lihogela umoya. Isibonelo, uzwa iphunga lesigaxa kude nebanga lekhilomitha. Ngasikhathi sinye, uyamnyonyobela ngokungabonakali, okushiya uphawu lungelona ithuba lokusindiswa.
Umbala wejazi ubuye ube nomthelela ekuzingeleni okuyimpumelelo - ngenxa yokuthi imhlophe, lokhu kubenza bacishe bangabonakali ezintabeni zeqhwa.
Ibhere lingalinda inyamazane isikhathi eside. Ngokushesha nje lapho ivele ngaphezulu, umhlaseli uyayithuntubeza ngezidladla ezinamandla bese eyidonsela phezulu. Kuyiqiniso, ukuze ithole inyamazane enkulu, ngokuvamile ibhere kufanele lilwe izimpi ezibucayi.
Ukukhiqiza kabusha
Ukuzala kwabesifazane kuqala lapho kufinyelela eminyakeni emithathu ubudala. Ibhere lingazala amawundlu angaphezu kwamathathu ngasikhathi. Futhi kukho konke ukuphila kwakhe angazala ama-cubs angadluli ku-15.
Imvamisa, amawundlu azalwa ngesikhathi sasebusika. Ngaphambi kokubeletha, owesifazane ulungiselela indawo - ukhipha umhume ojulile eqhweni, lapho izingane ezisanda kuzalwa zingafudumali nje kuphela kepha futhi ziphephile. Kuze kufike intwasahlobo, umama ondisa inzalo ngobisi lwebele, ngemuva kwalokho amawundlu ayaphuma ayohlola umhlaba.
Kumele kuqashelwe ukuthi noma sezivele zizimele ngokwengeziwe, oxhumana nabo nomama abakaphazanyiswa - baze bazimele ngokuphelele, ukunakekelwa komama akupheli. Ngokuqondene nobaba, akunakushiwo ukuthi abanandaba nezingane zabo, kepha kukhona amacala okuhlukunyezwa.
Ibhere elisendaweni emhlophe lingomunye wabamele abababazekayo emhlabeni wezilwane, futhi kungaba yihlazo uma linganyamalala ngokuphelele.
