12 p, 1.0 MB Changes in vegetation and fuel use from the Neolithic to the Middle Ages in the western Catalan plain / Piqué i Huerta, Raquel (Universitat Autònoma de Barcelona. Departament de Prehistòria) ; Vila Moreiras, Sílvia (Universitat de Lleida. Departament d'Història) ; Alonso, Natàlia (Universitat de Lleida. Departament d'Història)
This paper presents a synthesis of charcoal analysis data from the West Catalan plain, from the Neolithic to Medieval times. We discuss the changes and trends in the consumption of firewood. Collecting firewood was carried out in an environment characterized by open vegetation, which appears to have been dominating in the area since the Bronze Age. [...]

Aim Plant functional groups are widely used in community ecology and earth system modelling to describe trait variation within and across plant communities. However, this approach rests on the assumption that functional groups explain a large proportion of trait variation among species. [...]

The upper soil provides support, water, and nutrients to terrestrial plants and is therefore crucial for forest dynamics. We hypothesised that a tree's metabolic activity (and therefore its metabolome; the total set of metabolites) would be affected by both the depth of upper soil layers and water availability. [...]

We characterized the phenology of the vegetation at the global scale from the mean seasonal leaf area index (LAI) estimated from 1-km SPOT VEGETATION time series for 1999-2010. The satellite-derived phenology was spatially consistent with the global distributions of climatic drivers and biome land cover. [...]
