O ibhere elimnyama (ursus americanus). ECanada nase-United States. Eqinisweni, maningi amathuba okuthi umbone evezwe kumdlalo odumile waseMelika noma ochungechungeni. Ngale ndlela yePeritoAnimal, uzokwazi ukwazi imininingwane eyengeziwe kanye nokufuna ukwazi mayelana nalesi silwane esincelisayo esikhulu. Funda ukuze ufunde konke ngemvelaphi yebhere elimnyama, ukubukeka, indlela yokuziphatha nokuzala.

Umthombo
  • Melika
  • ECanada
  • I-U.S

imvelaphi yebhere elimnyama

ibhere elimnyama a izinhlobo zomhlaba ezincelisayo yomndeni wamabhere, odabuka eNyakatho Melika. Inani labantu lisuka enyakatho ye ECanada nase-Alaska esifundeni saseSierra Gorda eMexico, kufaka phakathi ugu lwe-Atlantic nePacific lwe I-U.S. Ukuhlalwa okukhulu kwabantu kutholakala emahlathini nasezifundeni zezintaba zaseCanada nase-United States, lapho sekuvele kuyinhlobo evikelwe. Ensimini yaseMexico, inani labantu liyindlala kakhulu futhi ngokuvamile lilinganiselwe ezindaweni ezinezintaba ezisenyakatho yezwe.


Lezi zinhlobo zachazwa okokuqala ngo-1780 nguPeter Simon Pallas, isazi sezilwane esihola phambili saseJalimane nesazi sezitshalo. Njengamanje, ama-subspecies ayi-16 ebhere elimnyama ayaziwa futhi, ngokuthakazelisayo, akuwona wonke anoboya obumnyama. Masibone ngokushesha ukuthi yini i- Ama-subspecies ayi-16 ebhere elimnyama abahlala eNyakatho neMelika:

  • I-Ursus americanus altifrontalis: uhlala enyakatho nasentshonalanga yePacific, kusukela eBritish Columbia kuya enyakatho ye-Idaho.
  • Ama-ambiceps e-Ursus americanus: Kutholakala eColorado, eTexas, e-Arizona, e-Utah, nasenyakatho neMexico.
  • I-Ursus americanus americanus: ihlala ezifundeni ezisempumalanga ye-Atlantic Ocean, eningizimu nasempumalanga yeCanada, nase-Alaska, eningizimu yeTexas.
  • I-Ursus americanus californiensis: itholakala eCentral Valley yaseCalifornia naseningizimu ye-Oregon.
  • I-Ursus americanus carlottae: uhlala e-Alaska kuphela.
  • I-Ursus americanus cinnamomum: bahlala e-United States, ezifundeni zase-Idaho, eWestern Montana, eWyoming, eWashington, e-Oregon nase-Utah.
  • ursus americanus emmonsii: Kutholakala kuphela eningizimu-mpumalanga ye-Alaska.
  • I-Ursus americanus eremicus: inani labantu lilinganiselwe enyakatho-mpumalanga yeMexico.
  • I-Ursus americanus floridanus: uhlala ezifundazweni zaseFlorida, eGeorgia naseningizimu ye-Alabama.
  • Ursus americanus hamiltoni: i-subspecies yendawo yesiqhingi saseNewfoundland.
  • I-Ursus americanus kermodei: uhlala ogwini oluphakathi neBritish Columbia.
  • I-Ursus americanus luteolus: uhlobo olujwayelekile empumalanga yeTexas, eLouisiana naseningizimu yeMississippi.
  • ama-ursus americanus machete: uhlala eMexico kuphela.
  • ursus americanus perniger: luhlobo lwendalo esiFundeni saseKenai (e-Alaska).
  • I-Ursus americanus pugnax: Leli bhere lihlala e-Alexander Archipelago kuphela (e-Alaska).
  • Ursus americanus vancouveri: uhlala kuphela eVancouver Island (Canada).

Ukubukeka nezici zomzimba zebhere elimnyama

Ngama-subspecies ayo ayi-16, ibhere elimnyama lingenye yezinhlobo zebhere ezinokuhlukahluka okukhulu kakhulu kokuziphatha kwabantu. Ngokuvamile, sikhuluma nge-a ibhere elikhulu eliqinile, yize incane kakhulu kunamabhere ansundu namabhere asezindaweni eziphakeme. Amabhere amnyama amadala ngokuvamile aphakathi 1.40 namamitha amabili ubude futhi ukuphakama kubuna phakathi kwamamitha ayi-1 no-1.30.


Isisindo somzimba singahluka kakhulu ngokuya ngama-subspecies, ubulili, iminyaka nesikhathi sonyaka. Abesifazane bangaba nesisindo esisuka ku-40 kuye ku-180 kg, kanti isisindo sowesilisa siyahlukahluka phakathi 70 no-280 kg. La mabhere ngokuvamile afinyelela isisindo sawo esiphezulu ngesikhathi sokuwa, lapho kufanele adle inani elikhulu lokudla ukulungiselela ubusika.

Ikhanda lebhere elimnyama line- iphrofayili yobuso eqondile, ngamehlo amancane ansundu, isifonyo esicijile nezindlebe eziyindilinga. Umzimba wayo, ngakolunye uhlangothi, uveza iphrofayili engunxande, ubude bayo bude kunebude bayo, imilenze yangemuva ibonakala yinde ukwedlula ngaphambili (icishe ibe ngamasentimitha ayi-15). Imilenze yangemuva emide futhi eqinile ivumela ibhere elimnyama ukuthi ligcine futhi lihambe endaweni eyi-bipedal, okuyisici esivelele kulezi zilwane ezincelisayo.

Ngenxa yezinzipho zawo ezinamandla, amabhere amnyama nawo uyakwazi ukumba nokuqwala izihlahla kalula kakhulu. Ngokuphathelene nejazi, akuwona wonke ama-subspecies amnyama abonisa ingubo emnyama. Ngaphesheya kweNyakatho Melika, ama-subspecies anombala onsundu, obomvu, ushokoledi, blonde, ngisho nokhilimu noma amhlophe angabonakala.


isimilo sebhere elimnyama

Ngaphandle kobukhulu bayo obukhulu nokuqina, ibhere elimnyama kakhulu ishesha futhi inembile lapho izingela, futhi futhi angakhuphuka ezihlahleni ezinde zamahlathi lapho ahlala khona eNyakatho Melika ukuze abalekele izinsongo noma ukuphumula ngokuthula. Ukuhamba kwaso kuyisici sesilwane esincelisayo se-plantigrade, okungukuthi, sisekela ngokugcwele amathe ezinyawo zaso phansi lapho sihamba. Futhi, kunjalo ababhukudi abanamakhono futhi bavame ukuwela izikhala ezinkulu zamanzi ukuze bahambe phakathi kweziqhingi zeziqhingi noma bawele besuka ezwekazini baye esiqhingini.

Ngenxa yamandla abo, uzipho lwawo olunamandla, ijubane lawo nezinzwa zawo ezikhule kahle, amabhere amnyama angabazingeli abahle kakhulu abangabamba inyamazane yobukhulu obuhlukahlukene. Eqinisweni, imvamisa zidla kusuka umuhlwa nezinambuzane ezincane kuye amagundane, izinyamazane, imfucumfucu, isalmon nezinkalankala. Ekugcineni, bangahlomula ngesidumbu esishiywe ezinye izidalwa noma badle amaqanda ukwengeza ukudla kwamaprotheni ekudleni kwabo. Noma kunjalo, imifino imelela cishe i-70% yokuqukethwe kwayo ukudla okunomsoco, kudla okuningi amakhambi, utshani, amajikijolo, izithelo namantongomane ephayini. Bathanda noju futhi bayakwazi ukugibela ezihlahleni ezinkulu ukuze baluthole.

Ngesikhathi sokuwa, lezi zilwane ezincelisayo ezinkulu zikhulisa kakhulu ukudla ezikudlayo, njengoba zidinga ukuthola amandla anele okwanele ukugcina umzimba ulinganisela kahle ebusika. Kodwa-ke, amabhere amnyama awafihli ubusika, kunalokho alondoloza uhlobo oluthile lokulala ebusika, lapho izinga lokushisa lomzimba lehla khona ama-degree ambalwa ngenkathi isilwane silele isikhathi eside emhumeni waso.

ukukhiqizwa kwebhere elimnyama

amabhere amnyama anjalo izilwane ezinesizungu abajoyina kuphela abalingani babo ngokufika kwenkathi yokukhwelana, eyenzeka phakathi kwezinyanga zikaMeyi no-Agasti, phakathi nentwasahlobo nehlobo laseNyakatho Nenkabazwe. Ngokuvamile, abesilisa bafinyelela ekuvuthweni ngokocansi kusukela ngonyaka wesithathu wokuphila, kanti abesifazane bakwenza lokho phakathi konyaka wesibili nowesishiyagalolunye wokuphila.

Njengezinye izinhlobo zamabhere, ibhere elimnyama liyi- isilwane se-viviparous, okusho ukuthi ukukhulelwa nokukhula kwenzalo kwenzeka ngaphakathi kwesibeletho sowesifazane. Amabhere amnyama abambezele ukukhulelwa, futhi imibungu ayiqali ukukhula kuze kube cishe amasonto ayishumi ngemuva kokukopishwa, ukuvimbela amawundlu ukuba azalwe ekwindla. Isikhathi sokumitha kulolu hlobo sithatha izinyanga eziphakathi kweziyisithupha kuya kweziyisikhombisa, kuthi ekugcineni owesifazane azale ingane eyodwa noma ezimbili, ezizalwa zingenaboya, zivalwe amehlo futhi isisindo esimaphakathi kusuka ku-200 kuye ku-400 amagremu.

Imidlwane izonceliswa omama bayo ize ibe nezinyanga eziyisishiyagalombili ubudala, lapho bezoqala khona ukuzama ukudla okuqinile. Kodwa-ke, bazohlala nabazali babo iminyaka emibili noma emithathu yokuqala yokuphila, baze bafinyelele ebudaleni bobulili futhi bakulungele ngokuphelele ukuhlala bodwa. Isikhathi sakho sokuphila esimweni saso semvelo singahluka phakathi Iminyaka eyi-10 nengu-30.

Isimo sokongiwa kwebhere elimnyama

Ngokwe-IUCN Red List of Endangered Species, ibhere elimnyama lihlukaniswa njenge isimo sokungakhathazeki kakhulu, ikakhulu ngenxa yobungako bendawo ehlala kuyo eNyakatho Melika, ukutholakala okuphansi kwezidalwa zemvelo nezinhlelo zokuvikela. Kodwa-ke, inani lamabhere amnyama lehle kakhulu kule minyaka engamakhulu amabili edlule, ikakhulu ngenxa yokuzingela. Kulinganiselwa ukuthi cishe Abantu abangu-30,000 ziyazingelwa unyaka nonyaka, ikakhulukazi eCanada nase-Alaska, yize lo msebenzi ulawulwa ngokomthetho futhi uhlobo luvikelwe.
