Forest and Agricultural Dynamics in the Haouz Plain Over the Last Millennium
Establishment and functioning of the savanna marshes of the Lopé National Park in Gabon since the termination of the African humid period and the arrival of humans 2500 years ago
Holocene paleoecological studies in tropical Africa are rare because most lakes either dried out at the termination of the African Humid Period or have since filled up. However, tropical sedge marshes can be an alternative to perform long-term ecological studies. The Lopé National Park (LNP) in Gabon is a mosaic of forest and savanna enclosed in the equatorial forest, where open areas facilitated the development of peat marshes accumulating sever…
Legacies of past human activities on one of the largest old-growth forests in the south-east European mountains

Cloud dynamic contribution to high-elevation peatland growth during the Holocene (Escalerani, Central Andes, Bolivia)
Changes in climate conditions during the Holocene are documented in different parts of South America, showing contrasting responses to global changes. This study was conducted in the wet puna at an elevation of 4040 m a.s.l. on the eastern side of the Cordillera Real in Bolivia near Lake Titicaca. Pollen, charcoal, and stable isotopes in a sediment core collected in the peatland of Escalerani were analyzed. Results revealed environmental changes …
Past tree cover of the Congo Basin recovered by phytoliths and δ13C along soil profiles
New Evidence of Human Activities During the Holocene in the Lowland Forests of the Northern Congo Basin
In the last decade, the myth of the pristine tropical forest has been seriously challenged. In central Africa, there is a growing body of evidence for past human settlements along the Atlantic forests, but very little information is available about human activities further inland. Therefore, this study aimed at determining the temporal and spatial patterns of human activities in an archaeologically unexplored area of 110,000 km 2 located in the n…
Coupled Rock-Eval pyrolysis and spectrophotometry for lacustrine sedimentary dynamics
In recent years, Nguène Lake and Kamalété Lake (Gabon, West Central Africa) have been studied repeatedly, providing comprehensive reconstructions of environmental changes over the last millennia. Both lakes are in different geomorphological and environmental settings. They are therefore excellent sites to test new methodological approaches. Indeed, the sedimentary cores provide various facies, and the previous studies provide references for calib…
Tracking land-cover changes with sedimentary charcoal in the Afrotropics
Fires have played an important role in creating and maintaining savannas over the centuries and are also one of the main natural disturbances in forests. The functional role of fires in savannas and forests can be investigated through examining sedimentary charcoal in order to reconstruct long-term fire history. However, the relationship between charcoal and vegetation structure in tropical grassy ecosystems remains to be elucidated. Here, we com…
West Central African Peoples
Tracing human history in west central Africa suffers from a scarcity of historical data and archaeological remains. In order to provide new insight into this problem, we reviewed 733 radiocarbon dates of archaeological sites from the end of the Late Stone Age, Neolithic Stage, and Early and Late Iron Age in Cameroon, Gabon, Central African Republic, Equatorial Guinea, Republic of Congo, and the western Democratic Republic of Congo. This review pr…
Evidence of moist niches in the Bolivian Andes during the mid-Holocene arid period
To examine the climate of the mid-Holocene and early human settings in the Andes when the Altiplano was recording the most arid phase of the Holocene, we analyzed plant-related proxies (pollen, phytoliths, diatoms, stable isotopes) from a sediment core sampled at high elevation in the Eastern Cordillera of Bolivia. Our study was carried out in the wetland of Tiquimani (16°12′06.8′′S; 68°3′51.5′′W; 3760 m), on a well-known pathway between Amazonia…
Insights into early Holocene hunter-gatherer mobility on the Peruvian Southern Coast from mollusk gathering seasonality
Variations in 14 C Reservoir Ages of Black Sea Waters and Sedimentary Organic Carbon During Anoxic Periods
Radiocarbon activity of dissolved inorganic carbon has been measured in the northwestern Black Sea. Both continental shelf and open-sea profiles show that surface waters are in equilibrium with the atmosphere. The observed distribution of 14 C activity shows a weak contribution of the deep 14 C-depleted CO 2 to the photic zone. Such a distribution of 14 C within the water column is unable to explain the aging of sedimentary organic matter and res…
Lowland rainforest response to hydrological changes during the last 1500 years in Gabon, Western Equatorial Africa
Pollen and δ 13 C TOM data obtained from two contrasting lake sequences (Lakes Kamalété and Nguène), located 200 km apart in the lowland rainforest of Gabon, provide complementary local and regional 1500-yr records of high resolution (15–30 yr) vegetation change. A combination of aquatic, semi-aquatic and terrestrial pollen showed in both records that the tropical rainforest increased during periods of high rainfall and decreased during drought i…
Strong El Niño events during the early Holocene
Intrashell oxygen and carbon stable isotope profiles (δ 18 O,δ 13 C) were established for Mesodesma donacium shells from the preceramic archaeological site, Quebrada de los Burros in coastal southern Peru, to reconstruct the sea-surface temperature (SST) variations and to estimate changes of the El Niño-Southem Oscillation (ENSO) interannual variability from the early Holocene to the present. Very strong oxygen isotopic excursions attributed to E…
