Libaaxa American: awoowe Rafaa ee bisadaha casri ah

Muddo dheer, ilaa iyo haatan markii nin noqday duurgal ah oo helay hub, on top of silsilad cuntada ee dhulkeenna ka ahaayeen wakiillo ka qoyska bisad. Dabcan, waxa aan ahaa our libaaxyada casriga ah, Jaguars, shabeelka iyo shabeelka, iyo awowayaashood bakhtiyeen, sida shabeel Saber-waayihiisa ama American Libaaxa. Ogaha libaax American shiidaa bakhtiyeen innoo, ama sida saynisyahano u wac, Panthera Leo atrox.

description noolaha

All oo libaaxyada iyo Jaguars, shabeelka iyo shabeelka waa xubno ka mid ah qoyska bisad (Felidae), waxaa iska leh BAHDDA ku Pantherinae - bisadaha weyn, iyo panulirus ku Panthera (Panther). Sida laga soo xigtay cilmi horumar ah ee noocyada this dhacay oo ku saabsan 900,000 oo sano ka hor, halka ay Africa casriga maanta. wakiilada Later of noocyada this qabsado qayb weyn oo ka mid ah Holarctic ah. The hadhaagii horrayn of carnivores ee Europe laga helay meel u dhow magaalada Talyaaniga ee Isernia, iyo da'dooda ka go'an in 700 000 oo sano. On qaaradda Eurasian oo ku saabsan 300,000 oo sano ka hor la deggan yahay libaax godka. Sababo la halkay ku xira inta America iyo Eurasia, qayb ka mid ah dadka ka mid ah bahal god helay iyada oo loo marayo Alaska iyo Chukotka ee North America, halkaas oo, ay sabab u go'doomin sii dheerayn sameeyay a dacawo cusub libaaxyada - American.

xiriirka qoyska

Sidaas darteed, muddo dheer shaqada si wadajir ah ay fuliyeen by Cilmi-ka Russia, Britain, Australia iyo Germany, waxaa la ogaaday in aan caalamka oo dhan waxaa ka jira saddex nooc oo libaaxyada. Maanta, hoygii halkii yar ku nool libaax oo casri ah. Laakiin isaga ka hor waxaa jiray laba innoo iyo noocyada bakhtiyeen maanta. First of dhan, taas libaax godkii (Panthera Leo spelaea), oo degganaa galbeedka Kanada iyo dhulka ku dhow oo dhan oo ah inta lagu guda jiro Eurasia Pleistocene ah. Intaa waxaa dheer, waxaa sidoo kale jiray libaax Maraykan (Panthera Leo atrox), kuwaas oo ku noolaa in waxa hadda waa Maraykanka. Iyo meelo ka mid ah South America. Waxa uu sidoo kale loo yaqaan libaaxa North American ama jaguar a Rafaa Negele. Sidaas darteed ee barashada cilmiga ah waxyaabaha la dhaxlo ee xoolaha lafo iyo bahal casri ah ay awoodaan in la dhiso in dhammaan saddex nooc oo libaaxyada in ay hiddawadayaasha of waa mid aad u dhow. Laakiin halkan waxa kale oo aan ogaaday saynisyahano: dacawo ah libaaxa American jiray go'doon hidaha ee in ka badan 340 000 oo sano, iyo inta lagu jiro waqti in uu ahaa mid ka duwan dacawo kale.

Xaggee bayse ka yimaadeen?

Markii hore, libaaxyada, kaasoo ka Africa iman qabsado dhulka Eurasia ka dibna gudbay biriijka dalka Beringia in ku xiran wakhtigaas la qaaradda Eurasian, North America, oo waxay bilaabeen inay yeeshaan qaaradda cusub. Seynisyahanno soo jeedinaya in dhacdo ee labada noocyada kala duwan ee North America ay sabab u tahay ka saarida wakiilada oo ka mid ah laba dadka iyadoo ay sabab u glaciation. Sida laga soo xigtay la xiqiijiyay in kale noocyada kala duwan: godka iyo libaaxyo American - waa wakiillo ka socda laba hirarka socdaalka ka Eurasia, ilaa xad fog ka soo midba midka kale in waqti.

Sidee buu u eeg?

Like kale bahal oo innoo, American Libaaxa waayay qiyaastii 10 000 oo sano ka hor. In uu waqti uu mid ka mid ah ugu weyn oo ugu khatarta badan ee xoolaha, oo dhererkiisu wuxuu gaari karaa saddex mitir oo ka sii ahaa, oo miisaankii oo gaadhay 300 dhadig, iyo labka iyo ilaa 400 kg. Ka mid ah aqoonyahaniinta weli wax heshiis ah oo ku saabsan Su'aasha ah in baar xoolaha ee sida faraciisii casriga ah, ama ma. Si kastaba ha ahaatee, oo muuqashadeeduna waxay ku Tilmaami cad: on lugaha awood ahaayeen dhagan, jir muruqa ah, madaxa loo saaraa taaj madaxa weyn, iyo gadaalba laga dabada dheer. midabka maqaarka, cilmi soo jeedinayaan, waxay ahayd adag, laakiin waxaa laga yaabaa ayaa xilli ahaan beddelay. The ugu morphologically la mid ah Ligers libaax American - Dhal libaax iyo tigress ah. Way adag tahay in la damacsan tilmaanta u ekaa American Libaaxa. dib u dhiska Photo of muuqaalkiisa aad nooga caawiso inay fahmaan sida aadka ah uu u eg yahay inuu casriga ah "qaraabo".

Halkaas oo uu ku noolaa?

Sidaas darteed goobta qaddiimiga ah ee hadhaagii xayawaanka this waxaa la helay in ka badan aag aad u ballaaran ka soo Peru si Alaska. Tani waxay ogol yahay saynisyahano ku doodaya in libaaxa American noolaa oo keliya ma aha ee Waqooyiga laakiin sidoo kale in gobollada qaar ka mid ah South America. Dad badan oo ka soo haray xayawaanka this laga helay aan ka fogayn Los Angeles. Xataa maanta, inkastoo horumarka la taaban karo ee sayniska, saynisyahano ma siin karo sababaha dhabta ah oo gaar ah oo ka lumay ee xayawaanka ku saabsan 10 000 oo sano ka hor. Waxaa jira mala saabsan yaraadan ee dalka calafka xoolaha iyo dhimashada xoolaha, cuntada American in libaaxyada sababta oo ah isbedel glacial iyo cimilada. Waxa kale oo jira version a lug ka mid ah dadkii hore in ay xasuuq of this ilaashadaan amaanaa.

Cuntada iyo tartamaya

American Libaaxa in uu waqti u ugaadhsan karo awoowayaasha ee elg casri ah oo qoraafiga, iyo sidoo kale dibi baadiyaha bakhtiyeen, oo geel ah reer galbeedka, dibi duurjoogta ah iyo fardo (Equus). Isla mar ahaantaana in North America ku noolaa iyo bahal kale oo waaweyn, sidoo kale bakhtiyeen.

Waayo, ilaalinta ciyaan ugaadhsigooda oo libaaxyada sababo ugaarsiga wada la raacin karaa. Ilaalinta ay cunto iyo territory diriray American Libaaxa Saber-waayihiisa Shabeel (Machairodontinae), ee yeey laga cabsado qadiimiga ah (Canis dirus) iyo orsadiiba waan soo food-gaaban (simus Arctodus).
