on biodiversity across the Holocene epoch. To enhance our understanding of current changes in diversity increasingly homogenised dominated by a few widespread species. As a result both REVEALS evenness and spatial Vegetation Estimates from Large Sites model have been used to explore spatiotemporal changes in vegetation and time windows covering the period from 11.7 ka cal BP to present . Space-time constrained clustering of the 2 ka cal BP and second summer-green forest 9.2 ka to 5.2 ka cal BP phases generally showed higher REVEALS vegetation composition and diversity across Europe? A pollen-based spatio-temporal approach
beginning to be surveyed. A recent modelling of sudden lake degassing confirms that Pavin area is a potential Degassing maar lakes were thought to be a new natural hazard until the Nyos Lake catastrophe 1986 . Historical Monoun 1984 and Nyos 1986 in Cameroon allow to propose a grid of degassing descriptors on lake and waters approaches implemented at Pavin to establish their past degassing history necessary to risk management. Lire l'intégralité with reported sudden neurologic diseases similar to those observed at Albano and Nyos. Their spontaneous and confirms that Lake Pavin remains a potential hazard, providing a model for assessing risks in other Degassing maar lakes were considered a new natural hazard until the Nyos Lake catastrophe in 1986, but (Auvergne, France), for the Last Two Thousand Years - A Comprehensive Study of Volcanic Phenomena
investigations remains a main issue. This study introduces a novel method to estimate soil moisture directly approaches to correct field data from geochemical mapping in diverse environments including a coastal region region in Portugal and a mountainous region in France. Our findings demonstrate that this simple efficient Uestimated r2 0.9715 . The model effectively corrected up to 70 of moisture-induced errors in metal concentrations least 55 in wetter soils France . This study offers a cost-effective efficient solution for employing pXRF in situ portable X-ray spectrometer measurements: A novel approach for correcting geochemical data across

In a world of drastic climatic and ecological changes our knowledge of how the environment influenced can contribute to connecting small-scale environment-induced influences on hominins to large-scale patterns behaviour is of the utmost importance. Archaeology plays a key role as it is the only discipline that studies studies empirical evidence of past societies responses to environmental change. Computational models generating conditions and simulation techniques are presented to provide an overview of the diverse approaches possibilities Changing Movements in a Changing World: Modelling Early Pleistocene and Early Middle Pleistocene Climatic
