Spoznajte najstarejše drevo na svetu, ki raste v Južni Ameriki

Starodavni macesen, ki so ga poimenovali tudi “pradedek” v južnem Čilu, bi lahko bil star več kot 5000 let.

Znanstvenikom sicer ni uspelo določiti točne starosti drevesa, saj ima to nenavadno debelo deblo, a sklepajo, da je to najstarejše drevo na svetu.

Zaradi prevelikega premera debla ne morejo prešteti vseh letnic, da bi lahko z običajnimi metodami določili njegovo natančno starost.

Macesen starejši od bora

Jonathan Barichivich, znanstvenik, ki je vodil raziskavo, je dejal, da vzorec, ki so ga pridobili, in druge metode datiranja kažejo, da je drevo staro do 5484 let in da po njegovih izračunih obstaja le 20-odstotna možnost, da je mlajše od 5000 let. Ocenjena starost za več kot pol tisočletja premaga sedanjega rekorderja, 4.853 let star bor v Kaliforniji.

Koliko časa mu je še ostalo?

Čeprav je macesen preživel številna obdobja človeške civilizacije, je Barichivich zaskrbljen za prihodnost “pradedka”. Tega namreč v narodnem parku Alerce Costero vsako leto obišče na tisoče ljudi, ki stopajo na njegove korenine in s seboj za spomin celo odnašajo koščke lubja.

»To je kot primerek, razstavljen v živalskem vrtu v groznih razmerah,« pravi. Ljudi je ob tem pozval, da razmislijo o tem, kaj pomeni živeti 5000 let, in postavijo svoje življenje in podnebno krizo v perspektivo.

It is used to ensure that the same poll does not re-appear if it has already been filled in. 365 days _hjMinimizedPolls Hotjar cookie. This cookie is set once a visitor minimizes a Feedback Poll widget. It is used to ensure that the widget stays minimizes when the visitor navigates through your site. 365 days _hjDoneTestersWidgets Hotjar cookie. This cookie is set once a visitor submits their information in the Recruit User Testers widget. It is used to ensure that the same form does not re-appear if it has already been filled in. 365 days _hjIncludedInSample Hotjar cookie. This session cookie is set to let Hotjar know whether that visitor is included in the sample which is used to generate funnels. 365 days _hjShownFeedbackMessage This cookie is set when a visitor minimizes or completes Incoming Feedback. This is done so that the Incoming Feedback will load as minimized immediately if they navigate to another page where it is set to show. 365 days _hjid Hotjar cookie. This cookie is set when the customer first lands on a page with the Hotjar script. It is used to persist the Hotjar User ID, unique to that site on the browser. This ensures that behavior in subsequent visits to the same site will be attributed to the same user ID. 365 days _hjRecordingLastActivity This should be found in sessionStorage (as opposed to cookies). This gets updated when a visitor recording starts and when data is sent through the WebSocket (the visitor performs an action that Hotjar records). Session hjTLDTest When the Hotjar script executes we try to determine the most generic cookie path we should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, we try to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed. Session _hjUserAttributesHash User Attributes sent through the Hotjar Identify API are cached for the duration of the session in order to know when an attribute has changed and needs to be updated. Session _hjCachedUserAttributes This cookie stores User Attributes which are sent through the Hotjar Identify API, whenever the user is not in the sample. These attributes will only be saved if the user interacts with a Hotjar Feedback tool. Session _hjLocalStorageTest This cookie is used to check if the Hotjar Tracking Script can use local storage. If it can, a value of 1 is set in this cookie. The data stored in_hjLocalStorageTest has no expiration time, but it is deleted immediately after creating it so the expected storage time is under 100ms.
