Abstract Natural disturbances such as volcanic eruptions provide a unique opportunity to study past ecological dynamics. Here we illustrate the response of terrestrial and aquatic ecosystems to volcanic eruptions in connection to prevailing climate c

Our field data from the Upper Palaeolithic site of Al-Ansab 1 (Jordan) and from a pollen sequence in the Dead Sea elucidate the role that changing Steppe landscapes played in facilitating anatomically modern human populations to enter a major expansi

An international research group is proposing a new research initiative, the Lake Van Drilling Project ‘PaleoVan’ within the framework of the International Continental Scientific Drilling Program (ICDP). The project mainly aims at obtaining high-r

The authors shed new light on the time frame and pathways followed by Homo sapiens on its journey from Africa to Europe and provides new insights into the intricate interplay of culture and environment during the past 200,000 years. The new findings
Instrumental data show that while the impact of volcanic eruptions on their immediate vicinity is destructive, long-term consequences can be beneficial. However, beyond last millennia observational data and ancient oral history, the detailed insights

Which routes did Homo sapiens take when spreading from Africa to Eurasia? The climatic conditions changed and with them the living conditions. Over the past twelve years, a research team has deciphered the complex interplay of cultural innovations, m

Several techniques are commonly used for quantitative climate reconstructions based on plant information from lake sediments. One of these is the creation of transfer functions that link current climate to current plant distributions and apply the re

The dating of pollen grains is emerging as the method of choice for lacustrine climate archives that contain few datable macrofossils. Due to the need for high-purity pollen concentrates, new methods are constantly being developed to precisely separa

Fires have accompanied terrestrial life from the beginning, yet with incomplete knowledge about feedback to paleoclimate and vegetation. Here, we have assessed how climate triggered the activity of vegetation fires in a 600,000 years continental reco
