Abstract
    The study of the evolution of a Crustacea Decapoda community from calcareous bottoms - strongly related with Posidonia oceanica, developed during 1986-1987, completes the overview of the structure and variability existing in this habitat. Four groups have been established, according to the abundance presence. The gualitative composition is similar to that found in other calcareous bottoms from the Southern Spain. So, the six more abundant species (belonging to the first and second groups) are the same. The fluctuations of the general structure and its evolution are controlled by the two dominant species, Athanas nitescens and Pisidia longicornis (form. longimana). The development of the Posidonia bed, which increases the sedimentation and protection, is, possibly, the responsible of the guantitative differences found.
