La ukhuseleko lwezityalo zendalo kunye nolondolozo lweentlobo ezisengozini yokuphela Ngoku yinkxalabo engundoqo kwizazinzulu, ii-arhente zikarhulumente, nabemi abanomdla kukhuseleko lokusingqongileyo. Uphononongo lwamva nje kunye nenkqubela phambili yetekhnoloji isivumela ukuba siqonde ngcono ukuba kutheni iintlobo ezininzi zezityalo zomthonyama zikwimeko esengozini, kunye nokuphuhlisa izixhobo zokubeka iliso kunye nokubuyisela.
I-ecosystems yaseMzantsi Melika, ngakumbi kwimimandla efana nombindi kunye namazantsi eChile, baye batshintsha kakhulu emva kokutshabalala kwezilwanyana ezikhulu, ezifana neemastodon, kumawaka eminyaka eyadlulayo. Olu tshintsho luneziphumo ezisavakala kubuchule bezityalo ezininzi bokuphila nokuzala.
Ukuphela kwe-megafauna kunye nefuthe layo kwiintyatyambo zendalo
Enye ye ezona zinto zifunyanisiweyo zezenzululwazi kule minyaka ilishumi idlulileyo Oku kuye kwaba sisiqinisekiso sokuba ukunyamalala kwezilwanyana ezinkulu ezifana ne-mastodons kuyaqhubeka nokuchaphazela ngqo izityalo zaseMzantsi Melika. Iqela leengcaphephe zamazwe ngamazwe, elikhokelwa yiYunivesithi yaseO'Higgins kunye ne-IPHES-CERCA eTarragona, kutshanje lipapashe ubungqina befosili obubonisa indlela ezi zilwanyana ezidlale ngayo indima ebalulekileyo ekusasazeni imbewu.
Ngayo uhlalutyo lwamazinyo angama-96 efosili Ifunyenwe phakathi kweLos Vilos kunye nesiqithi saseChiloé, abaphandi baye bafumanisa iintsalela ze isitatshi kunye nezicubu zezityalo ezivela kwiziqhamo ezizinyama, eqinisekisa ukuba i-mastodons idla ngokuphindaphindiweyo olu hlobo lokutya kwaye, emva koko, yanceda ukusabalalisa imbewu kwiindawo ezinkulu. Lo msebenzi wendalo, oyimfuneko ekuvuseleleni amahlathi, uye waphazamiseka ngequbuliso ukususela ekunyamakeni kwawo.
Uphando lubonisa ukuba Phantse i-40% yeentlobo zezityalo ezixhomekeke kwizilwanyana ezincancisayo ezinkulu ekusasazekeni kwembewu zisemngciphekweni. Kumbindi weChile. Xa kuthelekiswa, kwimimandla eshinyeneyo, umlinganiselo weentlobo zezilwanyana ezisemngciphekweni ungaphantsi kakhulu, ngokuyinxenye ngenxa yokuba izilwanyana ezinjengee<em>tapir nezinye iiprimates zisekho apho ezizalisekisa lo msebenzi, nangona ngokuyinxenye.
Ubudlelwane bokubambisana phakathi kwezityalo kunye ne-megafauna engasekho
Uphando luxhasa ithiyori ecetywayo kumashumi eminyaka eyadlulayo: izityalo ezininzi zomthonyama zavela iziqhamo ezinkulu, ezinomtsalane ngokuchanekileyo ukutsala izilwanyana ezinkulu ezazithutha kwaye zisasaza imbewu yazo kumgama omde. ukunyamalala kwe-megafauna yalutshintsha kakhulu olu lungelelwaniso lwendalo, ishiya iindidi ezininzi zezityalo zikwimeko esengozini.
Umsebenzi wenzululwazi, opapashwe kwijenali eyaziwayo yamazwe ngamazwe, ugxininisa indlela Ilahleko yezi zilwanyana ayithethi nje utshintsho lwezoological, kodwa nakwibhotani kunye nendaleko.Ukungabikho kwezinto ezisebenza kakuhle zokuzisasaza kuye kwasikel’ umda ukuveliswa nokwanda kweentlobo ezininzi zezinto eziphilayo, nto leyo eshiya ezinye zikwimeko emaxongo yaye kuthintela ukuveliswa ngokutsha kweentlobo ezithile zamahlathi endalo.
Iirekhodi zedijithali kunye nokuthatha inxaxheba kwabemi kulondolozo
Ukujongana nale nyaniso, kukho amanyathelo avelayo azama ukubandakanya uluntu ekuchongeni nasekukhuseleni izilwanyana ezisengozini. Kwiindawo ezikhuselweyo ezifana ne INahuel Huapi National Park, isixhobo sedijithali siphunyeziwe esivumela abahlali kunye neendwendwe ukuba babhale ngokulula ukuqwalaselwa kwezityalo zendalo kunye neentlobo ezisengozini.
Le nkqubo ubhaliso lwedijithali ludibanisa ngokuthe ngqo kuluhlu lwesizwe, ukuguqula imigqaliselo yabemi ibe lulwazi olufanelekileyo kulawulo nolondolozo. Isixhobo siyafikeleleka kwi-intanethi nakwi-intanethi, ukwenza ukubhaliswa kube lula nakwiindawo ezikude. Iincwadana zabasebenzisi kunye nenkxaso nazo zibonelelwa ukuze nabani na onomdla athathe inxaxheba kwaye anikele ngedatha ebalulekileyo.
El uluhlu lweentlobo eziphambili zolondolozo Iyafumaneka ukuze kuboniswane nayo, kwaye uluntu lunokuphonononga isicwangciso solawulo lwendawo ekhuselweyo ukuze lufunde ukuba zeziphi iintlobo ezithathwa njengezinto zendalo ezibalulekileyo. Intsebenziswano yoluntu ibalulekile ekuhlaziyeni nasekuphunyezweni kwezicwangciso zolondolozo ezilungelelaniswe nemingeni ekhoyo ngoku.
Ilahleko yonxulumano phakathi kwe-megafauna etshabaleleyo kunye nohlaza lwemveli kushiye iziphumo ezibonakalayo zeyantlukwano yendalo kunye nolungelelwaniso lwendalo lwemimandla emininzi yaseMzantsi Melika. Nangona kunjalo, ukuqhubela phambili kuphando lwe-paleontological kunye nokuthatha inxaxheba kwabemi ekurekhodweni kweentlobo kunye nokubeka iliso kunika izixhobo zokuhlangabezana nomngeni wokulondoloza kunye nokubuyisela inxalenye yeli lifa lendalo. Ukudityaniswa kwenzululwazi, ubugcisa kunye nentsebenziswano kunokwenza umahluko ekuthinteleni ezi zityalo zikhethekileyo ukuba zinyamalale ngonaphakade.
