Diversidad de grupos funcionales en la vegetación de la costa arenosa de los cayos Grande, Anclitas y Caguamas (archipiélago de los Jardines de la Reina, Cuba)

Sandy shores are known to be extreme ecosystems where the vegetation has evolved many morphological and physiological adaptations forits survival. With the aim of identify possible relationships between the vegetation ́s functional diversity with abiotic factors and its correspon-ding quantification, we collected data on the abundance and richness of the sandy coast vegetation complex in Grande, Anclitas and Caguamaskeys. Its flora is largely characterized by the dominance of hemicryptophytes and chamaephytes plants with nanophyllous leaves and displayingdispersal syndromes such as zoochory and anemochory. However, the functional groups ́ richness, in the present study, varies from one key toanother. Functional diversity is similar between the wet and dry seasons, and its spatial variation is influenced by the interplay of the set of abio-tic factors herein studied.
