The coastal sand-dune flora of the Gulf and Caribbean region of Mexico was analyzed to understand differences in floristic
composition and richness found along the coast. Each of the 655 species reported was classified according to its ecology and
distribution range by checking herbaria specimens, literature and specialists. Three groups were formed: (a) species with
predominantly coastal distribution; (b) ruderal or secondary species frequently found inland, common of disturbed areas such
as roadsides, abandoned fields or forming part of secondary growths; (c) inland species frequently found in other vegetation
types such as tropical dry or seasonal forest and grassland. A total of 71 coastal species, 237 ruderal/secondary and 336
species from other community types were found. The distribution of these groups was analyzed along 44 sites of the Gulf and
Caribbean, in the different dune habitats and for the dominant growth forms. Coastal species are more widely distributed;
they predominate in habitats with sand movement and the herbaceous component prevails. Ruderal/secondary species and especially
those belonging to other vegetation types frequently appear in only one or two sites occupying more protected or stabilized
habitats. The two latter groups considerably increase species richness of sand dune flora, but also pose interesting problems
for dune conservation. 相似文献

Palms are a resource of great importance in the tropics and are found in a variety of ecosystems, including the wetlands of the tropical coastal plains. In order to recover wetland ecosystems, we studied the traditional uses of wetland palms, by conducting interviews in the communities of four municipalities on the Gulf of Mexico coast. We found that people use five species of palm: Cocos nucifera, Sabal mexicana, Attalea liebmannii, Roystonea dunlapiana and Acrocomia aculeata. Main uses for the five species were for food and construction materials. Although palms are still used, traditional knowledge is declining in the younger generations, likely as a result of various social, cultural and economic factors. It is important to recover and promote the traditional use and value of palm trees, especially for the native species, because of both the economic benefits and the environmental services they provide. More participatory work with the inhabitants is needed to initiate palm breeding programs to assist in the recovery of wetland ecosystems. 相似文献
