Abstract

The aim of the study is to investigate, at local scale, the relationship between the distribution of Tetraclinis articulate and differents environmental factors: physical as elevation, orientation, solar rays incidence, drainage, slope; and biological as the competition with Pinus halepensis. Generalized linear models were used to describe this relation, offering its explanation by means of the major ecological theories. The study corroborates that the Tetraclinis articulate distribution limits are in the area, where the limiting factor is the water availability stated by the orientation. Tetraclinis articulate also presents a differential behaviour depending on the orientation: its physiological optimum is in the shaded one (north-east) but its ecological optimum is in the east becauseof competition with Pinus halepensis. The shaded orientation is taken up by a pinewood with some big size Tetraclinis articulate trees, the sunny-spot (south-south-east) is under control of a tetraclinar opened of high density of small size trees while the east is organized as a mosaic of Tetraclinis articulate patchs and Pinus halepensis patchs where there is a balanced competition between both.
