Las condiciones climáticas secas y cálidas del sur de Europa representan límites claros para el crecimiento del haya europea (Fagus sylvatica) cerca del límite sur de distribución de la especie, pero no está claro cómo la aridificación y los cambios en los regímenes de precipitación estacional afectarán a estos bosques a nivel individual. En este … Leer más
Climate predictions for the Mediterranean Basin include increased temperatures, decreased precipitation, and increased frequency of extreme climatic events (ECE). These conditions are associated with decreased tree growth and increased vulnerability to pests and diseases. The anatomy of tree rings responds to these environmental conditions. Quantitatively, the width of a tree ring is largely determined by … Leer más
ABSTRACT: This work presents a method for the reconstruction of fragmentary daily precipitation datasets. The method aims to preserve the local and temporal variability characteristic of high-frequency precipitation data, and does not use the time-structure of the data. Based on the precipitation values recorded at closest neighbours during a target day, 2 reference values (RVs) … Leer más
Abstract. A high-resolution daily gridded precipitation dataset was built from raw data of 12,858 observatories covering a 10period from 1950 to 2012 in peninsular Spain and 1971 to 2012 in Balearic and Canary Islands. The original data were quality controlled and gaps were filled on each day and location independently. Using the serially-complete dataset, a … Leer más
Abstract Drought recurrence in the Mediterranean is regarded as a fundamental factor for socioeconomic development and the resilience of natural systems in context of global change. However, knowledge of past droughts has been hampered by the absence of high‐resolution proxies. We present a drought reconstruction for the northeast of the Iberian Peninsula based on a … Leer más
Abstract In Mediterranean areas with limited availability of water, an accurate knowledge of growth response to hydrological variables could contribute to improving management and stability of forest resources. The main goal of this study is to assess the temporal dynamic of soil moisture to better understand the water-growth relationship of Pinus halepensis forests in semiarid … Leer más
