Ngaba ukhe wawabona amaxwebhu angezilwanyana zaseAfrika? Kwityala, ngokuqinisekileyo uye wafumana ithuba lokubona indlela i-savannah etshintsha ngayo unyaka wonke: ibe ngummandla owomileyo kakhulu, ogutyungelwe zizityalo eziphantsi.. Kuxhomekeka kuloo mmandla, kukho nemithi ethile, embalwa ukuba sinokuyithelekisa naleyo ifumaneka ehlathini okanye ehlathini, kodwa exatyiswa kakhulu zizilwanyana zalapho, njengoko iyisebenzisela ukutya nokuzikhusela elangeni.
Kodwa kweli nqaku masithethe ngezityalo zesavannah, oko kukuthi, izityalo eziye zakwazi ukuziqhelanisa nemeko-bume ekungekho kuzo zonke.
Siyifumana phi i-savannah?
Umfanekiso – Terpsichores // Imephu yeesavannah ezitropikhi kunye nezantsi.
I-savannah yase-Afrika ngokuqinisekileyo iyaziwa kakhulu kuzo zonke. Ithatha indawo ezininzi kwilizwekazi, ukusuka kumazantsi entlango yeSahara ukuya eMzantsi Afrika. Kodwa le ayisiyiyo kuphela indawo apho kukho i-savannahs:
Ukuba sinqumla echibini, siye eMelika, siyayibona loo nto kukho ama-savannah kunxweme lwePasifiki nakwiLlanos yaseColombia-Venezuelan; Kwesinye isiphelo sehlabathi, eOstreliya, wonke umntla welizwekazi uthathwa njenge-savannah. KwaseAsiya, emantla eIndiya, zikwakho.
Zeziphi iindidi zamashiti akhoyo?
Kukho iindidi ezine: i-intertropical, iqondo lokushisa, iMeditera kunye neentaba. Iimpawu zayo zezi zilandelayo:
- i-intertropical savanna: Imozulu yeTropikhi okanye iTropiki, kunye namaqondo obushushu aphakathi kwe-12 kunye ne-30ºC. Iimvula zezonyaka; ixesha eliseleyo imbalela yingxaki enkulu kakhulu, kangangokuba izilwanyana ezahlukahlukeneyo kufuneka zifudukele kwiindawo ezicinga ukuba ziya kufumana amanzi, njengeendlovu umzekelo.
- i-savannah epholileyo: njengoko amaqondo obushushu epholile kwaye kunetha kancinci, umhlaba uqulethe izondlo ezininzi. Kodwa ewe, imbalela inokuba yingozi, kodwa ayihlali ixesha elide njengama-savannahs aphakathi kweetropiki.
- i-savannah ye-mediterranean: inokufumaneka kuyo yonke iplanethi apho imozulu ifana kakhulu neMeditera (oko kukuthi: ishushu kakhulu kwaye isomile ehlotyeni, kwaye incinci ebusika, kunye nemvula encinci). Ngoko ke, yindawo eyinkqantosi, apho izityalo zikhula emhlabeni ezinezondlo ezimbalwa.
- Iintaba ze-savannah: Ikwabizwa ngokuba yi-alpine okanye i-subalpine savannah, kuba ikwiindawo apho zifumaneka khona ngakumbi. Iimvula zininzi kakhulu, ngoko kukho ubomi obuninzi kwezi ndawo.
Zeziphi izityalo esizifumana kwisavannah?
izityalo ze-savannah isenokuba ngamagqabi, amatyholo, imithi kunye nezityalo ezinencindi. Ngokuxhomekeke kwindawo ohlala kuyo emhlabeni, uya kufumana imvula eninzi okanye encinci, yingakho kungekho savanna ezimbini ezifanayo.
Ngoko, makhe sibone ukuba zeziphi ezinye:
I-Acacia tortilis

Zininzi ii-acacias ezihlala kwii-savannahs, kodwa enye yezona ziyaziwa kakhulu inokuba I-Acacia tortilis. Yinto eqhelekileyo esiboniswa nguGoogle xa sijonga imifanekiso ye-savannah yaseAfrika. Ngumthi owenza ikomityi ngohlobo lweparasol, enokufikelela kwiimitha ezi-5-6 ububanzi.
Ifikelela kubude obuziimitha ezingama-14, ukuba iindlovu ziyayishiya. Kwaye ezi zizilwanyana ezithanda ukutya amagqabi omnga. Kwiifilimu, banokubonwa begawula imithi ukuze bafikelele kumagqabi ebebengenakukwazi ukuwatya.
IBaobab (Adansonia)

El Baobab ngumthi okhula ngokucothayo ovelisa isiqu esityebileyo kakhulu, kangangokuba kuye kwafunyanwa imizekelo apho kuye kwafuneka abantu abaliqela ukuba bayamkele.
Ikhula e-Afrika, e-Madagascar nase-Australia, kwaye ibonakala ngokuba namagqabi awela ngexesha lonyaka elomileyo, kwaye intshula ngeemvula.. Inokufikelela kwiimitha ezingama-30 ubude, kwaye iphuhlisa isithsaba esinamasebe kancinane.
Iintsholongwane ze-Euphorbia

La Iintsholongwane ze-Euphorbia ngumthi onencasa okanye ityholwana abaninzi bethu abadla ngokuba nalo kwingqokelela yethu okanye egadini. Sisityalo esiyinzalelwane e-Afrika esifikelela kubude obufikelela kwi-15 yeemitha. Isithsaba sayo sinamasebe kakhulu xa sivuthwa, kwaye sicukene kakhulu.
Ikhula ngesantya esihle, nangona njengazo zonke izityalo ze-savannah, ithanda ukushisa. Xa kubanda, imisebenzi yabo iyancipha.
Hyphaene thebaica

Zimbalwa iintende ezihlala kwii-savannahs, kwaye zimbalwa kakhulu ezo sebe, kodwa Hyphaene thebaica ufumene kwi-savannah yaseAfrika indawo elungileyo yokuhlala. Ifikelela kubude obuziimitha eziyi-10-15, kwaye inamagqabi amile okwefeni.. Ukongeza, iziqhamo zayo ziyatyiwa; enyanisweni, amaYiputa amandulo akazange alibazise nokuthabatha abambalwa ukuya engcwabeni.
Ukuhluma kwayo kulula kwaye kuyakhawuleza, nje ukuba imbewu isemgangathweni, kodwa ayixhathisi iqabaka, ngoko ukuba ulawula ukuba nayo, kuya kufuneka uyikhusele ngaphakathi ukuba imozulu iyabanda.
Iprosopis affinis

Ikwabizwa ngokuba yicarob, Ngumthi onameva oyinzalelwane yaseMzantsi Melika ofikelela kubude obumalunga ne-10 leemitha. Isithsaba sayo sinamagatsha amaninzi, kwaye inamaqabunga amancinci, amancinci, aluhlaza.
Ikhula ngokukhawuleza, kwaye iyakwazi ukumelana nembalela ngaphandle kwengxaki.
