1964 metais JAV tyr\u0117jas Donaldas Curry, nor\u0117damas i\u0161tirti med\u017eio rieves, liep\u0117 nukirsti pu\u0161\u012f Nevados valstijoje. V\u0117liau paai\u0161k\u0117jo, kad tai buvo beveik 4 900 met\u0173 am\u017eiaus medis \u2013 vienas seniausi\u0173 patikimai datuot\u0173 pasaulyje.<\/p>\n

\u0160i istorija apra\u0161oma pranc\u016bz\u0173 leidinyje \u201eScience et Vie\u201c ir da\u017enai minima kaip skaudus pavyzdys, kaip moksliniai tyrimai gali negr\u012f\u017etamai pakenkti unikaliai gamtos vertybei.<\/p>\n

D. Curry tyrin\u0117jo sen\u0173j\u0173 ledynme\u010di\u0173 klimato s\u0105lygas, o med\u017eius naudojo kaip nat\u016bralius \u201earchyvus\u201c \u2013 j\u0173 riev\u0117se u\u017efiksuoti dr\u0117gm\u0117s ir temperat\u016bros poky\u010diai. Pirmiausia jis band\u0117 paimti m\u0117gin\u012f specialiu gr\u0105\u017etu, ta\u010diau \u012frankis pasirod\u0117 per trumpas, \u012fstrigo masyviame kamiene, ir tyrimas \u012fstrigo tiesiogine prasme.<\/p>\n

Galiausiai, gavus JAV mi\u0161k\u0173 tarnybos leidim\u0105, tyr\u0117j\u0173 grup\u0117 nusprend\u0117 med\u012f nupjauti. Tik po to, kai pj\u016bvis buvo nu\u0161lifuotas ir prad\u0117tos skai\u010diuoti riev\u0117s, atsiv\u0117r\u0117 tikrasis atradimo mastas.<\/p>\n

Kaip paai\u0161k\u0117jo pu\u0161ies am\u017eius<\/h2>\n

Suskai\u010diavus rievi\u0173 skai\u010di\u0173, j\u0173 rasta 4 862. Ta\u010diau tai dar nebuvo visas med\u017eio am\u017eius: pj\u016bvis padarytas ma\u017edaug dviej\u0173 metr\u0173 auk\u0161tyje, tod\u0117l pirmieji augimo metai \u012f skai\u010diavim\u0105 nepateko.<\/p>\n

D\u0117l \u0161ios prie\u017easties specialistai tikr\u0105j\u012f med\u017eio am\u017ei\u0173 \u012fvertino ma\u017edaug 4 900 met\u0173 ar net daugiau. Medis buvo \u017einomas \u201ePrometheus\u201c vardu.<\/p>\n

Leidinys atkreipia d\u0117mes\u012f \u012f simbolin\u0119 detal\u0119: \u0161i pu\u0161is augo dar gerokai anks\u010diau, nei buvo pastatyta Did\u017eioji piramid\u0117 Gizoje. Pats mokslininkas, kaip teigiama, kur\u012f laik\u0105 abejojo rezultatais ir skai\u010diavimus kartojo, ta\u010diau skai\u010dius nesikeit\u0117.<\/p>\n

Kod\u0117l \u0161ios pu\u0161ys gyvena t\u016bkstantme\u010dius<\/h2>\n

Tokios r\u016b\u0161ies pu\u0161ys auga ypa\u010d at\u0161iauriomis s\u0105lygomis \u2013 ties mi\u0161ko riba, kur joms tenka i\u0161tverti ir stipr\u0173 \u0161alt\u012f, ir sausr\u0105. D\u0117l itin l\u0117to augimo j\u0173 mediena tampa labai tanki ir atspari.<\/p>\n

Tai padeda med\u017eiams i\u0161likti nepaisant vabzd\u017ei\u0173, grybelio ar net gaisr\u0173. Kitaip tariant, j\u0173 ilgaam\u017ei\u0161kum\u0105 lemia ne palankios, o kaip tik ribin\u0117s gyvenimo s\u0105lygos.<\/p>\n

Po kilusio pasipiktinimo \u2013 grie\u017etesn\u0117 apsauga<\/h2>\n

\u201ePrometheus\u201c sunaikinimas suk\u0117l\u0117 pasipiktinim\u0105 JAV ir prisid\u0117jo prie platesnio jud\u0117jimo, siekusio geriau saugoti itin senus med\u017eius bei teritorijas, kur jie auga. Tai tapo vienu i\u0161 impuls\u0173 stiprinti apsaugos principus.<\/p>\n

1986 metais \u0161iame regione \u012fkurtas Great Basin nacionalinis parkas. \u0160iandien dal\u012f \u201ePrometheus\u201c kamieno galima pamatyti parko lankytoj\u0173 centre.<\/p>\n

Taip pat minima, kad kai kuri\u0173 kit\u0173 sen\u0173 pu\u0161\u0173 augimo vietos n\u0117ra atskleid\u017eiamos s\u0105moningai \u2013 siekiant jas apsaugoti. Tyr\u0117j\u0173 vertinimu, dalis \u0161i\u0173 med\u017ei\u0173 jau gali b\u016bti perkop\u0119 5 000 met\u0173 rib\u0105.<\/p>\n","protected":false},"excerpt":{"rendered":"
