Etude historique de la végétation durant le tardi-glaciaire et le post-glaciaire en Peräpohjola (Laponie méridionale en Finlande) par la méthode sporo-pollinique
On the basis of pollen‑analytical investigations of sediments from five lakes, an attempt is made to describe and explain the vegetational history of Peräpohjola (Finland), following the withdrawal of the continental ice sheet. Special attention is paid to the regional late‑glacial pollen flora con...

On the basis of pollen‑analytical investigations of sediments from five lakes, an attempt is made to describe and explain the vegetational history of Peräpohjola (Finland), following the withdrawal of the continental ice sheet.
