that the ratio between the number of sapwood and heartwood rings varies across the Alps. At the same predicts the cambial age of L. decidua trees based on the number of heartwood rings. By extension this model same time the indicator developed in this work is not suitable for a determination of wood origin raising phases accurate estimation of the age of harvested wood and information on the geographical origin of wood interactions. In this study we compiled a large dataset of L. decidua samples from across the European Alps European larch sapwood: a model for predicting the cambial age and for a more accurate dating - Dendrochronologia
alterations on the land-cover. This challenges the hypothesis that vegetation in the Mid-Holocene was modifications of land-cover dynamics is key to understanding the human role in the Earth system. Recent advances contributes valuable insights to the onset of agriculture as the start of the Anthropocene. Lire la suite study aims to evaluate the role of human impact on European land-cover over the past 6000 years by comparing climate model outputs. The climate model uses natural forcings only and therefore the computed vegetation anthropogenic land-cover modifications throughout the second half of the Holocene. Population estimates correlate This study quantifies European anthropogenic land cover changes using human pressure index (HPI). HPI published data on land use. High HPI values in the Mid-Holocene suggest significant impact of early impact on European land-cover of second half of the Holocene
modern humans. The extinction of so many large herbivores during the last 50 000 years and the loss of megaherbivores 1000 kg from most of the continent before the Pleistocene Holocene transition is likely to have had cascading woody habitats. The herbivores alive today in Europe are only a small remnant of the large species that evaluate these effects within the European temperate forest biome we examine the abundance change of three Taxus baccata before and after the late-Quaternary downgrading of the region''s large herbivore fauna shrubs in European temperate woodlands prior to the late-quaternary extinction of megafauna

site in the Pyrenees or in the Alps elsewhere in Europe. We tentatively link this moraine to the 8.2 ka behavior is much less constrained except for the Little Ice Age period. In this study we attempt to bridge this constituting the most robust directly dated Holocene glacier chronology in the Pyrenees. The moraine age While the Late Glacial evolution of Pyrenean glaciers is rather well-known Holocene glacier behavior paleoclimatic interpretation of this Holocene glacial evolution in conjunction with the radiocarbon ages from nearby Holocene glacier evolution in the Pyrenees based on 36Cl cosmic-ray exposure dating (Troumouse Cirque
comparing the nature of the pedestrian human or a robot. Based on the results of this experiment and the literature modifying the robot trajectory and glancing at the human is necessary to significantly increase the usability altering the trajectory and by showing the robot awareness of the human presence through the robot head humans is still an open problem especially in confined locations e.g. narrow corridors doors . This article and using its head to glance at the human. Experiment 2 evaluated this behavior in real situations of Evaluating the Impact of Time-to-Collision Constraint and Head Gaze on Usability for Robot Navigation
video games. The physical characteristics of HUD that is the physical appearance of the information on Experiments 1 2 and the semantic characteristics that is the composition nature and content of the information within the game. The performance of more experienced players was particularly affected in this case. In assessed. The results showed that players performance and experience were impacted when the semantic characteristics characteristics of the HUD elements were manipulated and when their nature was relevant to the main task players Head-up displays in action video games: the effects of physical and semantic characteristics on player

dating back to the Late Pleistocene long before the advent of agriculture. Quantifying the extent of vegetation pollen-based vegetation reconstructions for the Last Interglacial and the Early Holocene. Differences between explain the pollen-based vegetation patterns in Europe during these periods. To explore this issue we HUMLAND results closely matching the pollen-based vegetation cover. The updated ABM covers a broad temporal incorporates the effects of hunting on herbivores and their influence on vegetation regeneration. The results This study demonstrates that Neanderthals and Mesolithic foragers significantly altered European vegetation On the ecological impact of prehistoric hunter-gatherers in Europe: Early Holocene (Mesolithic) and Last
to deforestation and the decline in native wood resources in the Philippines. This study presents LUNTIAN mountain forest managed by University of the Philippines Los Baños. The model integrates biophysical processes reflecting the complex interplay between financial incentives and rule compliance. To assess the model s 17-year rotation the final tree population increased by 55 . These findings illustrate the potential of LUNTIAN LUNTIAN to support the exploration of sustainable ITP management strategies in the Philippines by offering The study shows that the LUNTIAN agent-based model effectively integrates ecological, economic, and social management strategies for industrial tree plantations in the Philippines, demonstrating both profitability and Plantation for Promoting Sustainable Harvesting in the Philippines
