Holocene paleoenvironments in southeastern Minnesota ^ chasing the prairie-forest ecotone
This paper uses a multi-proxy approach involving pollen, plant macrofossils, speleothem isotopes, and alluvial history of streams to reconstruct the history of prairie expansion and contraction along the prairie-forest border of southeastern Minnesota, USA. Early Holocene forests were replaced by prairie along this border, but eastward expansion of prairie stalled for 2000 yr when the prairie-f...

متن کاملReconstructing Forest Savanna Dynamics in Africa Using a Cellular Automata Model, FORSAT
Large areas of savannas are found in Africa in climatic zones favourable to humid tropical forests: they are relicts of past dry periods and forest domains are naturally expanding. Men have influenced the transgression, especially by starting savanna fires. FORSAT is a stochastic cellular-automaton model dedicated to the forest-savanna mosaic on a landscape scale, taking into account savanna fi...
متن کاملVegetation Dynamics in the Upper Guinean Forest Region of West Africa from 2001 to 2015
The Upper Guinea Forest (UGF) region of West Africa is one of the most climatically marginal and human-impacted tropical forest regions in the world. Research on the patterns and drivers of vegetation change is critical for developing strategies to sustain ecosystem services in the region and to understand how climate and land use change will affect other tropical forests around the globe. We c...
