“…The great divergents found in this study between quantitative and allozyme differentiation supports the idea that maritime pine is a complex species with regional adaptations. Although extensive gene flow has been estimated in P. pinaster using molecular markers (Nm = 3.02; Salvador et al, 2000), high quantitative differ-entiation is detected in this study. Long and Singh (1995) and Lynch (1995) showed that in nature two populations can experience high gene flow and be different for a quantitative trait.…”

“…Quantitative differentiation in total height of pairs of populations along the cline only fails to show divergences in two pairs of populations (4-5 and 6-7). Both sets are located in the main post-glacial migration pathway of P. pinaster in the Iberian Peninsula (Salvador et al, 2000). Lagerkrantz and Ryman (1990) have shown that historical patterns can partly account for quantitative variation.…”

“…This results in several adaptations of the species in growth and survival (Alía et al, 1995). Studies of genetic variation have shown great population differences both with molecular markers (Baradat and Marpeau, 1988;Petit et al, 1995;Vendramin et al, 1998;Salvador et al, 2000;Ribeiro et al, 2001) and quantitative traits. A high level of genetic differentiation in adaptive traits has been reported in maritime pine for survival, adaptation to different climatic conditions, growth and growth phenology, resistance to insects and drought tolerance (Matziris, 1982;Guyon and Kremer, 1982;Kremer and Roussel, 1986;Alía et al, 1995Alía et al, , 1997Harfouche et al, 1995).…”

“…The Iberian Peninsula could be considered the main pathway of the different groups, since all the three main groups are present, as well as eight of the geographical races. A latitudinal cline has been described in the Iberian Peninsula with an unclear geographical structure in the Atlantic region (Salvador et al, 2000;Ribeiro et al, 2001). This pattern has been explained as the result of a migration pathway from putative glacial refugia in mountain ranges near the Mediterranean basin (south-eastern Spain) to the Atlantic area of P. pinaster.…”

F-statistics were employed to analyse quantitative and allozyme variation among 19 native populations of maritime pine (Pinus pinaster Ait.). Fourteen polymorphic allozyme loci were used to provide an empirical basis for constructing a null hypothesis to test natural selection as a determinant of quantitative evolution in stem form, total height growth and survival at 30 years old. Hidden biases, that may result in a difference between quantitative (Q ST ) and allozyme (F ST ) differentiation which are not because of the action of natural selection, were avoided by comparing pairs of populations using linear models. All quantitative traits showed higher differentiation than allozymes. The highest divergence was

“…This result corresponds to earlier findings that tropical trees tend to present high levels of genetic diversity (Hamrick and Loveless, 1989). Further, Salvador et al (2000) showed that a range in genetic variation of forest tree from low to very high depending upon specific population. Broader area of sampling from geographically distinct populations is the possible cause of high gene diversity in present study (Premoli et al, 2001).…”

We determined the environmental correlates of vascular plant biodiversity in the Baetic-Rifan region, a plant biodiversity hotspot in the western Mediterranean. A catalog of the whole flora of Andalusia and northern Morocco, the region that includes most of the Baetic-Rifan complex, was compiled using recent comprehensive floristic catalogs. Hierarchical cluster analysis (HCA) and detrended correspondence analysis (DCA) of the different ecoregions of Andalusia and northern Morocco were conducted to determine their floristic affinities. Diversity patterns were studied further by focusing on regional endemic taxa. Endemic and nonendemic alpha diversities were regressed to several environmental variables. Finally, semi-partial regressions on distance matrices were conducted to extract the respective contributions of climatic, altitudinal, lithological, and geographical distance matrices to beta diversity in endemic and nonendemic taxa. We found that West Rifan plant assemblages had more similarities with Andalusian ecoregions than with other nearby northern Morocco ecoregions. The endemic alpha diversity was explained relatively well by the environmental variables related to summer drought and extreme temperature values. Of all the variables, geographical distance contributed by far the most to spatial turnover in species diversity in the Baetic-Rifan hotspot. In the Baetic range, elevation was the most significant driver of nonendemic species beta diversity, while lithology and elevation were the main drivers of endemic beta diversity. Despite the fact that Andalusia and northern Morocco are presently separated by the Atlantic Ocean and the Mediterranean Sea, the Baetic and Rifan mountain ranges have many floristic similarities – especially in their western ranges – due to past migration of species across the Strait of Gibraltar. Climatic variables could be shaping the spatial distribution of endemic species richness throughout the Baetic-Rifan hotspot. Determinants of spatial turnover in biodiversity in the Baetic-Rifan hotspot vary in importance between endemic and nonendemic species.
