Estudio de la macrofauna bentónica, zona intermareal (sustrato blando), de la bahía de Santander

Abstract

During the year 1979-1981, the species composition of the soft bottom intertidal zone of the bay of Santander (northern Spain) has been studied. 72 species from, 83 sampling stations have been processed by applying different indexes: Czechanovski's association, diversity and equitability. The distribution of the most significant species found in the samples is mapped, as well as the percentages of the main zoological groups. Sanders rarefaction method, as an additional help for the definition of the zones, is also used. #
