Plant diversity, dispersion, community similarity, and vegetation description in united arab emirates. II eastern coast

Abstract

Papers presented at The gulf symposium on Environmental biology, University of Qatar, 7-9 May 1994 *********** The vegetation on the eastern coast of UAE was studied in 3 undisturbed sites. Dispersion, species-area, and community similarity were investigated. Cluster analysis and regression correlation were calculated. Diversity parameters used were richness, heterogeneity, and evenness indices, habitat and vegetation patterns are described. Dispersion was more contagious at P<0.01 in the three communities. Species-Area were typical of desert ecosystem with high R2values. Community similarity analysis (5 methods) reflected modest similarity between Diba and Dhadna and dissimilarity with Al-Fujairah. Cluster analysis confirms similarity calculations. Correlation's give poor r-values. Diversity richness in Diba, Al-Fujairah, and Dhadna were 3, 3.9, and 2.6 (Margalef); 1.9, 2.3, and 1.6 (Menhinick), respectively. Heterogeneity and evenness were discussed in details.
