Geomorphological evidence and Pleistocene refugia in Africa

Auteur :
NICHOL, J.E.

Description :
New geomorphological evidence from satellite images is interpreted in the light of recent work on Quaternary desert advance in West and Central Africa to suggest that regions currently supporting tropical lowland rain forest were during the Quaternary period, covered by windblown sand in the form of linear desert dunes. These findings have implications for Pleistocene refugia in Africa and may explain both the relative paucity and high degree of endemism observed among African biota.
