Abstract
The present study provided an investigation of the floristic analysis, vegetation composition and species distribution along 100 m intervals of the elevation gradient (2000 m a.s.l.) on Jabal Musa (south Sinai, Egypt), and assessed the role of elevation and other soil parameters controlling plant diversity. It is a study on altitudinal variation in vegetation in a very dry climate. The vegetation structure, growth forms, and species diversity were analyzed within the 7 elevation belts on Jabal Musa area, 44 sample plots, 81 species (including one bryophyte), and 17 examined environmental factors including altitude. Asteraceae, Lamiaceae, Zygophyllaceae and Brassicaceae contributed about 41% of the species, represented in all belts. Based on the Bray-Curtis dissimilarity coefficients, it exhibited floristically homogeneous higher belts than the lower belts. Along moisture gradient, the Non Metric Multidimensional Scaling (NMDS) ordination was able to distinguish the different vegetation belts along the altitudinal gradient. The vegetation groups of the lower elevations occupied the negative side of Axis 1 while those of elaqsaa higher elevations occupied the positive end. CCA was applied to assess the relationships between soil parameters, species composition and vegetation groups. Altitude, coarse and fine sand fractions, magnesium and bicarbonates had significant correlations with diversity indices more than the others.
