Abstract
- XV Congreso Nacional de la AEET (El valor ,de la Naturaleza para una sociedad global), 18-21 de octubre, Plasencia, Cáceres.<br />One of the main concerns of ecologists is to understand which factors (biogeographical, physiographical, disturbance, etc.) control ecosystem structure and function. It is surprising that lithology has rarely been considered despite its potential cascading effects on resource availability and ecological conditions. The project LITHOFOR aims to shed light on the role of lithology in forest ecosystem responses to climate change by focusing on pine (Pinus pinaster), Andalusian-fir (Abies pinsapo) and cork-oak (Quercus suber) forests across the unique natural laboratory representedby the Baetic and Rif ranges (S. Spain- N.-Morocco). In the western Mediterranean-Alborán region, climate conditions shift from hyperhumid to semiarid in scarcely a hundred kilometers along West to East longitudinal gradients, and its world-wide renowned geotectonic and lithological complexity allows for abundant forest stands across contrasting lithological contacts. The project is a coordinated multidisciplinary effort of forest ecologists, plant physiologists, geologists, soil scientists, biodiversity researchers and modelers to compare forest structure and functio n among three contrasting lithologies (carbonated, metapelites and ultramafic rocks). Results illustrate that lithological types influence the shape and intensity of patterns along climatic gradients (and in respo nse to drought) for variables as stand structure, tree growth, foliar and root functional traits, litter decomposition and nutrient cycling, and bi ological communities composition (plants, soil nematodes and microbes). This advocates that litho/edaphological factors deserve greater attention.
