Climate or migration: what limited European beech post-glacial colonization?

Basil Andrew Stansfield Davis

AimDespite the recent improvements made in species distribution models (SDMs), assessing species' ability to migrate fast enough to track their climate optimum remains a challenge. This study achieves this goal and demonstrates the reliability of a process ...

Drivers of Holocene Land Cover Change in Europe

Pamela Collins

The modern vegetation of Europe is a product of its history. Climate change, plant migration, and human activity have all been important drivers of Holocene (11,500 years ago to the present) vegetation dynamics, but it is difficult to disentangle the relat ...
