Tre secoli per scoprire tutte le specie di alberi che popolano l’Amazzonia. È questo, secondo una ricerca condotta dal Field Museum di Chicago, il periodo necessario per terminare il percorso verso la scoperta di tutte le 16'000 specie stimate nel 2013. Ad oggi, quelle censite sarebbero 11'676, suddivise in 140 famiglie. Lo studio è stato pubblicato su “Scientific Reports”.
Le specie di piante nella foresta pluviale sono più di quelle presenti in tutto il resto del mondo, ma fino a tre anni fa il loro numero esatto era un mistero.
Gli esperti hanno infatti dovuto analizzare, grazie a un vasto progetto di digitalizzazione dei dati e dei campioni, le collezioni presenti nei musei di tutto il mondo, con lo scopo di capire quante fossero già state descritte e quante invece mancassero ancora all’appello.
