Izwe lanamuhla liguquka ngejubane elingacabangeki, futhi lokhu akusebenzi empilweni yabantu kuphela, kepha nasempilweni yezilwane. Izinhlobo eziningi zezilwane zanyamalala unomphela emhlabeni wethu, futhi singafunda kuphela ukuthi ngubani omele umbuso wezilwane owahlala kuleplanethi yethu.
Izinhlobo ezingavamile zifaka phakathi izilwane ezingekho engcupheni yokuqothulwa ngesikhathi esithile, kodwa kunzima ukuzihlangabeza emvelweni, njengomthetho, zihlala ezindaweni ezincane futhi zingamanani amancane. Izilwane ezinjalo zinganyamalala uma izimo zazo zokuhlala ziguquka. Isibonelo, uma isimo sezulu sangaphandle siguquka, kwenzeka inhlekelele yemvelo, ukuzamazama komhlaba noma isiphepho, noma ushintsho oluphuthumayo ezimweni zokushisa, njll.
IRed Book ibeka izilwane njengezilwane ezisengcupheni yokushabalala ezisivele zisengcupheni yokuqothulwa. Ukusindisa lezi zinhlobo ekuqothulweni ebusweni bomhlaba, abantu kudingeka bathathe izinyathelo ezikhethekile.
IRed Data Book yase-USSR iqukethe abanye abamele abahlobene nezinhlobo zezilwane ezisengozini yokuqothulwa
I-Frogtooth (Semirechsky newt)
Ihlala eDzhungarskiy Alatau, etholakala ebangeni lentaba (phakathi kweLake Alakol noMfula i-Ili).
I-Semirechensky newt incane kakhulu, iba nobude obusukela kumasentimitha ayi-15 kuye kwayi-18, kanti uhhafu wosayizi kube ngumsila wentsha. Isisindo esiphelele singu-20-25 amagremu, inani laso lingaguquka ngosayizi kuye ngesifanekiso esithile nokugcwaliswa kwesisu salo ngokudla ngesikhathi sokukala nesikhathi sonyaka.
Ezikhathini zamuva nje, ama-newts aseSemirechye ayethandwa kakhulu phakathi kogogo nogogo bethu. Futhi inani labo eliyinhloko lalisezakhiweni zabo zokuphulukisa. Amakhemikhali okuphulukisa ayenziwa ngamaswidi futhi athengiselwa abantu abagulayo. Kepha lokhu bekungaphezu nje kokuthola ulwazi ngamanga futhi nemithi yesimanje isuse lolu bandlululo. Kepha sebebhekane neshwa elilodwa, ama-newt abhekene nenye, indawo yabo yokuhlala yangcoliswa kakhulu futhi yafakwa ushevu ngezinto eziyingozi. Futhi, umthelela omubi ubangelwa indawo engakhethwanga kahle yizakhamuzi zendawo. Zonke lezi zinto ezingezinhle ziholela eqinisweni lokuthi amanzi ahlanzekile lapho izintuthwane zijwayele ukuba khona khona aphenduke isigaxa esinoshevu esingcolile esenzelwe impilo yezidalwa ezingadingi ukuvikelwa nakancane.
Ngeshwa, inani eliphelele labamele izintuthwane zeSemirechye alikwazi ukusungulwa. Kepha iqiniso elisobala ukuthi inani labo labantu liyancipha minyaka yonke.
Sakhalin musk inyamazane
Lezi zinhlobo zisabalele kuyo yonke iplanethi, ngaphandle kwe-Antarctica, New Zealand ne-Australia. Kuyinto iqembu lama-artiodactyls, elihlanganisa iqembu elibanzi lezilwane ezincelisayo.
I-artiodactyl yabameleli abaningi bezinyamazane ze-Sakhalin musk ukuba khona kweminwe emine ngemuva nangemuva kwezilwane. Unyawo lwazo luhlukaniswe ngokubonakalayo ngamahafu amabili nge-axis ehamba phakathi kwezinzwani ezimbili zokugcina. Phakathi kwazo, izimvubu ziyingqayizivele, ngoba yonke iminwe ixhunywe ulwelwesi, ihlinzeka isilwane ngokusekelwa okuqinile.
Izinyamazane zeMusk ezivela emndenini wezinyamazane. Lezi zilwane zihlala e-Eurasia, eMelika nase-Afrika, kanye naseziqhingini eziningi zasolwandle. Izinhlobo ezingama-32 zezinyamazane ze-musk zitholakele.
Izimvu zase-Altai zezintaba
Ngaphandle kwalokho ibizwa ngokuthi i-argali. Kuwo wonke ama-subspecies akhona we-argali, lesi silwane sihlukaniswa nosayizi ohlaba umxhwele kakhulu. I-Argali, njengezimvu zasentabeni, ihlala ezindaweni ezinezintaba lapho kukhula khona utshani obunesihlabathi noma i-steppe notshani.
Esikhathini esedlule, okungukuthi ngekhulu le-19 nasekuqaleni kwekhulu lama-20, i-argali yayisabalele impela, kodwa abazingeli kanye nokufuduswa kwenani elikhulu lemfuyo kwathonya inani lalesi silwane, esisalokhu sincipha.
