Nove revolucionarne snimke visoke rezolucije koje koriste specijalni algoritam otkrile su da, suprotno popularnom mi\u0161ljenju, u pustinjama Sahel i Sahara postoji najmanje 1,8 milijardi stabala. <\/p>\n\n\n\n

Tim od 24 znanstvenika iz Europe, SAD-a i Afrike otkrio je da je tzv. subvla\u017ena zona iznena\u0111uju\u0107e ispunjena biljnim svijetom.<\/p>\n\n\n\n

“Bili smo jako iznena\u0111eni da u Saharskoj pustinji raste toliko puno drve\u0107a”, izjavio je glavni autor Martin Brandt, docent geografije na Sveu\u010dili\u0161tu u Kopenhagenu. <\/p>\n\n\n\n

“Svakako postoje ogromna podru\u010dja bez ikakvog drve\u0107a, ali jo\u0161 uvijek postoje podru\u010dja s velikom gusto\u0107om stabala. \u010cak i izme\u0111u pje\u0161\u010danih dina, tu i tamo raste neko drve\u0107e”, nadodao je.<\/p>\n\n\n\n

Uz pomo\u0107 mo\u0107nog algoritma i 11.000 satelitskih snimki visoke rezolucije, znanstvenici su uspjeli prebrojati stabla. Brandtovo detaljno brojanje pojedina\u010dnih stabala otkrilo je gusto\u0107u od \u010dak 13,4 po hektaru, objavio je Nature<\/a><\/em>.<\/p>\n\n\n\n

Istra\u017eivanje je isklju\u010dilo drve\u0107e ili grmlje s malim kro\u0161njama, ra\u010dunaju\u0107i samo one s prosje\u010dnom veli\u010dinom kro\u0161nje od 12 metara kvadratnih. <\/p>\n\n\n\n

Stru\u010dnjaci koji su se bavili ovim istra\u017eivanjem izjavili su da \u0107e se uskoro mo\u0107i mapirati lokacija i veli\u010dina svakog drveta diljem svijeta. <\/p>\n","protected":false},"excerpt":{"rendered":"
