| (1) Based on vegetation relevés of sample units along transects perpendicular to the coastline, the mangal ecosystem of Gazi Bay (Kenya) has been investigated.(2) An indirect gradient analysis is performed by the ordination method Detrended Correspondence Analysis.(3) The first ordination axis can be interpreted in terms of resistance of the different species to flooding.(4) A similar zonation pattern is found as described by Walter & Steiner (1936).(5) Zonation is closely connected with morphological and ecophysiological features of the mangrove species. Therefore stomatal density has been measured. <i>Sonneratia</i> has by far the lowest stomatal density, <i>Lumnitzera</i> the highest. |

| Three transects through the mangrove, at right angles to the coastline and at increasing distance from the sea were studied. A number of pneumatophores was collected along each transect, the epiphytic vegetation identified and quantified, and the data analyzed with different mathematical techniques. It was concluded that: 1) the lowest algal cover on each pneumatophore is in the basal zone (0-5 cm above the substratum); the cover of the other zones is not significantly different; 2) the total cover of the pneumatophores from one transect diminishes from the seaward margin towards the land (due to increasing desiccation in higher zones); 3) there are no significant differences between the epiphytic vegetation on <i>Sonneratia</i> and... |
