Ecological behavior of Quercus suber and Quercus ilex inferred by topographic wetness index (TWI)

摘要: The ecological behaviors of a network pure evergreen oak stands (Quercus suber L. and Quercus ilex L.) in the Central-Western Mediterranean Basin were investigated toward climatic edaphic factors implemented with application topographic wetness index (TWI). A Categorical Principal Component Analysis (Catpca) using soil physico-chemical parameters was performed on 23 cork holm aim to understand better effectiveness TWI for characterizing ecology two species. Catpca pointed out that, although are able growth similar conditions, they show different terms needs tolerance water content. confirmed such results at local scale, allowing highlighting some interesting features species differential ecology. Although both be drought-tolerant, heliophilous revealed dominate landscape wettest soils high values—indicating capacity tolerate stresses due periods waterlogging—, while shade-tolerant prevails low-medium values—drier mesophilous sites. Despite vegetation science is relatively recent, encouraging suggest considering this user-friendly synthetic investigations modeling.
