POLLEN ANALYSIS FROM ECOLOGICAL AND LATITUDINAL GRADIENT IN MOROCCO

Multivariate analyzes of this pollen study on sites reflect local vegetation and the three main zones are well separated. Such a study on ordination of canonical and two way cluster methods can be applied to paleozoic pollen records that provide a reliable picture of vegetation on a site. It shows that the latitudinal / altitudinal gradient is highlighted in assemblages pollen, with markers taxa different stages of vegetation: including quercus suber in the meso-mediterranean quercus canariensis in the supra- mediterranean and cedrus and abies in the highlander. This relationship can be used in the past to reconstruct paleo staging of the vegetation. I assert that these quaternary pollen with the vegetation can be applied on the paleozoic spore and any other organic fossils.
