Diversity of functional groups in the vegetation sandy seashore of the Grande, Anclitas and Caguamas Cays (Jardines de la Reina Archipelago, Cuba)

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

Crisis of work as a social integration factor

This article analyzes the process of deterioration of the work as a source of social rights and as a social integration element. The context of this process is the passage of a wage-labour society with stable employment to other where the labour relations are deregulated. This aim was tackled by means of quantitative and qualitative techniques. Secondary sources of statistical information were used together with interviews to experts of the institutional sphere. The results of this research show the emergence of a new exclusive model of social cohesion based on intensification and generalization of social inequalities and job insecurity. In this new model of social cohesion, it is noted that the integration strategies of people have less and less support from Government and people are neglected. This process appears in the four spheres that classify the social exclusion risks factors: the structural, the institutional, the relational and the individual.
