Nevertheless, when investigating the underlying causes of a species’ distribution, it is important to assess both the abiotic and the anthropogenic factors (land-use variables) that might have influenced the species’ distribution. That is especially true in the Mediterranean Basin, where natural ecosystems have undergone significant changes in response to anthropogenic pressures in the region. In this study, we examined the effects of abiotic and anthropogenic factors on the distribution of Quercus faginea in the Spanish Central Pyrenees. Information on the presence–absence of Q. faginea, and abiotic and anthropogenic variables, were derived using GIS based on digital maps and aerial photographs. To identify and quantify the factors that have affected significantly the spatial distribution of Q. faginea, we used Bayesian Model Averaging and hierarchical partitioning. In the Spanish Central Pyrenees, on a broad scale, abiotic variables; i.e. climate and lithology, were the factors that had the greatest effect on the spatial distribution of Q. faginea; however, recently introduced pine plantations and previous livestock pressure have had a negative effect on the distribution of Q. faginea in the region. | Descripción: | 9 páginas, 1 tabla, 1 figura.-- El PDF del artículo es su versión post-print. | Versión del editor: | http://dx.doi.org/10.1007/s11258-010-9880-0 | URI: | http://hdl.handle.net/10261/38148 | DOI: | 10.1007/s11258-010-9880-0 | ISSN: | 1385-0237 |
