- Biological spectrum and dispersal syndromes in an area of the semi-arid region of north-eastern Brazil Elimar Alves de Lima José Iranildo Miranda de Melo Medicina Caatinga disperser diaspores life forms The biological spectrum and diaspores disper sal syndromes of the species recorded in a stretch of vegetation in a semi-arid region within the Cariri En vironment Protection Area, Boa Vista, Paraíba State (northeast) Brazil, are described. Collectio ns were made from fertile specimens, preferentially bearing fruit, over a 15-month period. Life forms an d syndromes were determined by field observations using specialized literature. One hundred and sixty-six species, dist ributed into 123 genera and 41 families, were reported. Abiotic syndromes (autochory and anemochory) repr esented 69.7% of all syndromes identified, whilst 30.3% of the species were classified as zoochory. In the life form spectrum therophytes represented 27.7% of species, followed by small- and medium-sized phanerophytes (23.5%) and chamaephytes (22.3%). The occurrence of hemicryptop hytes (9%), cryptophytes (0.6%) and species that could not be classified according to their life forms was also recorded (16.9%). Results showed that the biological spectrum and the dispersal syndromes ar e highly relevant to understand the structure and function of this phytocenos e, with subsidies for the development of other studies in the semi-arid areas of northeastern Brazil. 2015 artículo científico 1679-9291 https://www.redalyc.org/articulo.oa?id=307239651011 en http://www.redalyc.org/revista.oa?id=3072 Acta Scientiarum.
