| Mangrove forests are unique ecosystems which provide a range of important goods and services. However, they are suffering high rates of destruction around the world, and will be one of the first ecosystems affected by the predicted sea level rise. This project aims to establish re-planted experimental plots of mangroves in cleared areas. Experimental treatments will consist of plots of three different tree species, along with all possible multi-species mixtures and unplanted controls. Volunteers will assist in planting mangroves, and in measuring a range of biological and physical parameters relevant to important ecosystem functions, such as productivity and growth rates, susceptibility to disease, faunal abundance (of fish and crabs) and sedimentary... |

| 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... |

| (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. |

| The size spectra and biomass of the nematode assemblages in the sediments of <i>Avicennia marina, Bruguiera gymnorrhiza, Ceriops tagal</i> and <i>Sonneratia alba</i> at Gazi Bay (Kenya), are described. Weighted mean length (resp. dry weight) of the nematodes varies from 0.543 to 1.367mm (resp. 0.10 to 0.19µg) and differs considerably from geometric and median values. Nematodes become longer (around <i>Avicennia</i> and <i>Sonneratia</i>) or remain similar in length (around <i>Bruguiera</i> and <i>Ceriops</i>) with increasing depth into the sediment. Body elongation is suggested to be an adaptation to low oxygen and food supply, which are under the impact of... |
