owona mthi mdala emhlabeni

Siyazi ukuba indalo ayiyeki ukusothusa. Kanye njengoko esenza ngezilwanyana ezingaqhelekanga, ukwakwenza nezityalo. Kule meko, sithetha ngayo owona mthi mdala emhlabeni. Lo mthi mdala emhlabeni ngoweentlobo UPinus longaeva egqama ngokuba nobomi obude.

Kweli nqaku siza kukuxelela ukuba zeziphi iimpawu kunye ne-curiosities yomthi omdala kunabo bonke emhlabeni.

I-Great Basin likhaya le-bristlecone pines, eyaziwa ngokuba yiPinus longaeva, enobomi obude. Le mithi ineziqu eziluthuthu ezijijelwe ngokuqinileyo njengentambo eshinyeneyo ngenxa yeenkulungwane zokubethwa ngumoya nemvula. Enye into efak’ isandla ekuchumeni kwabo kule meko kukungabikho kokhuseleko. Kwiindawo eziphakamileyo kufuphi ne-11,000 ezinyaweni e-Nevada, kukho i ukungabikho okucacileyo kwengca, ukhula, izinambuzane kunye nezinye iindlela zokhuphiswano. Ngaphezu koko, akukho bantu bakhoyo abanokuthi bengaqondanga baqalise ukutshisa amahlathi. Ukungabikho kwemithi ekufutshane nako kuthintela ukwanda kwezifo kunye neentsholongwane.

Ezi zidalwa zangaphambi kwembali azinawo amarhamncwa endalo, nto leyo evumela ukuba ziphile iminyaka. Umsebenzi wabo oyintloko kukuqokelela kunye nokugcina amanzi kwiinaliti zabo, ezinokuhlala iminyaka kwaye ngokuthe ngcembe batyebe ngokuqokelela nganye. Ukhuni lukhula ngokukhawuleza kangangokuba alukwazi ukungena kwizinambuzane okanye izifo ezifana nooqongqothwane okanye izifo.

Imithi yepine ehlala ixesha elide ikwazi ukuqhubeka ngolu hlobo kangangeenkulungwane, nangaphambi kokudalwa kweepiramidi zaseGiza. Umzekelo woku nguwo UMethusela, umthi wompayina ohlala ixesha elide obekwe kwiiNtaba eziMhlophe zaseCalifornia. KUNYELo mthi wompayina urekhodwe njengowona mthi wakudala wompayina ophilayo, kwaye idatha yeringi yomthi ibonisa ukuba ibiphila iminyaka engama-4.853.

UMethusela njengowona mthi mdala emhlabeni

uMethusela

Izazinzulu kudala zikholelwa ukuba umthi othile unesihloko seyona nto indala ephilayo emhlabeni. Nangona kunjalo, Eli bango lisanda kubuzwa.. Umphandi osuka eChile uye wasebenzisa iindlela ezingaqhelekanga zokumisela ubudala bePatagonian cypress, uhlobo lomthi olwahlukileyo kulo mthi ukhankanywe ngasentla. Ukuba iziphumo zophononongo lwabo zichanekile, oko kuya kuthetha ukuba lo mthi womthi waseMzantsi Merika uye wodlula owona mthi umdala, nto leyo ewenza ube ngumnini omtsha wesihloko sowona mthi mdala emhlabeni.

Ngelixa ibango livuse umdla wabaphandi abathathu, bahlala bethandabuza, ngokuyinxenye ngenxa yokuba imithi ye-cypress, ekhula kumahlathi ashinyeneyo ashushu, Banobomi obahlukileyo ngokumangalisayo kune bristlecone pines. Nangona zombini ezi ntlobo ziphila ixesha elide, zombini zijamelene nombuzo wokuba ziya kuphila iminyaka emininzi kusini na.

Umchasi womthi ophila ixesha elide

imithi ephila ixesha elide

Imvelaphi yaseChile naseArgentina, umsipres we patagonian, okanye iAustrocedrus chilensis, igqalwa njengeyesibini kweyona mithi iphila ixesha elide ehlabathini. Owayesakuba ngumnini wesihloko, ingonyama yeminyaka engenakuthelekiswa nanto, yafunyanwa ekuqaleni kwe-1990 ngokubala amakhonkco okukhula kwelogi egawulweyo; yaphila iminyaka engaphezu kwama-3.600 (uhlobo lwesithathu oluphila ixesha elide, i-sequoia enkulu, nayo yachongwa ngale ndlela yaza yaphila iminyaka engama-3.266).

Izifundo zobomi obude bemithi

Inqaku likaGabriel Popkin kwiSayensi libonise ukuba isazi sezendalo u-Jonathan Barichivich kunye nomfundi oye wafumanisa ingonyama yasendulo wayehlola omnye umthi kwipaki yelizwe laseChile. Ukukhupha isampuli ye-cypress core, abaphandi basebenzisa i-drill yesinyathelo esifana ne-T. Nangona isixhobo sokugaya asikwazanga ukufikelela kumbindi womthi, ongaphezu kweemitha ezingama-30 ububanzi, isibini sasebenzisa imodeli yekhompyutha kunye isampuli kunye nolwazi oluvela kwimisesane yeminye imithi yelarch ukuqikelela oko umthi wawuneminyaka emalunga ne-5.400 ubudala, kunye ne-80% enokwenzeka yokuba wawumdala kuneminyaka engama-5.000.

Nangona iziphumo zophando zikaBarichivich azizange zihlolwe ngontanga, uye wazinikezela kwiinkomfa ezininzi. UNate Stephenson, isazinzulu esaphumayo kwi-United States Geological Survey obefunda iisequoia ezinkulu iminyaka engamashumi amane, uthi iziphumo zibangel’ umdla. Nangona kunjalo, uya kulinda ukugweba de uBarichivich apapashe iphepha elichaza indlela yakhe. Nangona kunjalo, uStephenson uvakalisa imincili malunga neziphumo ezinokuthi zibe khona zophando xa wayethetha noPopkin.

Abanye abantu, kwelinye icala, Bayathandabuza ukwamkela iziphumo ze-Barichivich. UPeter Brown, umdali weRocky Mountain Tree Ring Research, umbutho oqokelela idatha kwimithi emidala yehlabathi, ungomnye wabo. UBrown ucinga ukuba indlela kaBarichivich ayiqhelekanga kakhulu ukwenza ingxelo eqinisekileyo ngaphambi kokuyipapasha. "Ukuze ufike kwiminyaka yobudala, kufuneka wenze uqikelelo oluninzi," utshilo uBrown.

Intsingiselo yomthi ayikho into eBrown imibuzo. Nangona kunjalo, uqikelelo lobudala balo mthi lusekwe kwiqhezu kuphela lombindi wawo, nto leyo ebonisa ukuba ubuncinci iminyaka engama-2.400, iwubeka phakathi kwemithi emidala eyi-10 kuluhlu lukaBrown. Ngaphandle koku, uBrown uhlala ethandabuza ngenxa yezinye izizathu ezininzi. Eyona nto ibalulekileyo kubo kukuba Ubudala obuqikelelwayo bungaphezu kowona msipres mdala owaziwayo ngeminyaka engaphezu kwe-1.500, njengoko uBrown echaza.

NgokukaBrown, kukho umahluko obonakalayo phakathi kokusingqongileyo okukholisa ukuxhasa imithi emidala kunye nokusingqongileyo kwePatagonian cypress. Imithi ekumhlaba ongeyondlwan’ iyanetha, njengeendawo zokuhlala ezinomkhenkce nezinzima zepayina yamandulo, inamandla okuqhubela phambili ngokuthe ngcembe. Okuphikisanayo, Amahlathi ashinyeneyo azele bubulembu kunye namandla azele yingozi.

Izazinzulu zisahlulelene ngesizathu sokuba imithi ethile ikwazi ukuphila ixesha elide kangaka. Ngokutsho kukaBrown, "Ndicinga ukuba imithi ayifuni ukufa ngenxa yobudala, ngokungafani nezilwanyana ezincelisayo. Kunoko, into yangaphandle imele ingenelele ize ibangele ukuba inyamalale.

Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nomthi omdala emhlabeni kunye neempawu zawo.
