across the Holocene epoch. To enhance our understanding of current changes in diversity and its impact Large Sites model have been used to explore spatiotemporal changes in vegetation and regional diversity spatial variations in composition within one time frame and turnover temporal variation in composition within only expanded but also shifted in composition with major increases in cereals and other anthropogenic time windows covering the period from 11.7 ka cal BP to present . Space-time constrained clustering of the increasing human impact across the holocene result in simplification of vegetation composition and diversity
around each site in relation to land-abandonment. Our study shows that in addition to allowing long-term are a critical step to better understand the patterns and processes of changes in vegetation and land-cover However such estimates are difficult to obtain from pollen data due to their lack of spatial dimension and Algorithm LRA to reconstruct the spatial and temporal patterns of upland vegetation in the Bassiès Valley was then used to reconstruct the 200-year history of local land-cover dynamics at 10 to 20-year intervals patterns of upland vegetation over the last 200 years in the northern pyrenees: Example from the Bassiès valley
effectively corrected up to 70 of moisture-induced errors in metal concentrations in the wettest soils and bias during in situ investigations remains a main issue. This study introduces a novel method to estimate reliable use in almost any field condition. The study was conducted using soil samples and in situ pXRF soil surface measurements in Estarreja Portugal and Vicdessos France . In the first experiment the innovative measurement errors obtained in moist soils using multiple regression. In the second experiment metal Modeling soil moisture from in situ portable X-ray spectrometer measurements: A novel approach for correcting
differentiated recovery in rainfall since the 1990s statistically significant only at Kanel break in 1998 32 p 0 onset of the rainy season and a reduction in prolonged dry spells in Matam and Ranérou. This recovery contrasts persistent decline observed in Podor characterised by a 28.3 decrease in annual rainfall a nine-day shortening dramatic expansion of cowpea cultivation in Linguère 592 in production since 2006 and diversification agro-ecosystems. This study analyses rainfall variability in north-eastern Senegal over the period 1963-2020 and shows that spatial and temporal variations in precipitation in northeastern Senegal have a significant impact impact on agricultural systems, leading farmers to develop various adaptation strategies such as expanding Six Decades of Rainfall Variability in North-Eastern Senegal: Seasonal Variations, Intra-Seasonal Dry

This led to recognition of some features linked to the two site well to understand the taphonomy of the rock art favouring the elaboration of preservation plans in the Valcamonica an Alpine valley in northern Italy boasts one of Europe s largest concentrations of open-air perspective on the rock art sites-landscape relations in the Upper Palaeolithic of Valcamonica (N-Italie)
while also seeking to connect to global historical patterns. This talk examines trends in this scholarship highlighting some of the main themes in recent work and placing it in national and international context Mediterranean Studies has become increasingly popular in US academic institutions with the formation of dedicated and book series. Many of these approaches look back to Fernand Braudel s influential conception of the Mediterranean and new directions over a decade of developments in Mediterranean Studies

analysis of ancient gold items in the context of provenance studies in archaeology and history may characterize highlight metal circulation in a given space and time however they cannot point to a specific geological province possible to obtain precise and accurate measurements of Pb Cu and Fe isotope compositions in gold matrices uncertainties are in good agreement with the long-term 1.5 years reproducibilities 2SD estimated in the course repeated measurement of in-house standards.
