We sampled three tropical estuaries, two times each, on ten stations distributed along each system. Six replicates were collected in each station for the benthic macroinfauna and sediment samples for grain size and inorganic contaminant analyses. There were finer sediments at the lower than at the upper estuarine portions. There was a decrease in the diversity, at family level, from marine to freshwater and the differences on the structure of the benthic assemblages were mostly spatial. In spite of the many different characteristics of the three estuaries (e.g. catchment size, pollution levels, proximity with the inner continental shelf) several consistent patterns of benthic macrofauna distribution along these systems were still observed. It suggested a general empirical model regarding the distribution of different benthic invertebrates along tropical salinity gradients which can be tested in different estuaries around the world.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2014-05-29T12:02:29Z No. of bitstreams: 1 Francisco Barros.pdf: 1150670 bytes, checksum: ffca939f0bda301c1c6ca0fdacb118fd (MD5)Approved for entry into archive by Alda Lima da Silva (sivalda@ufba.br) on 2014-11-11T18:05:12Z (GMT) No. of bitstreams: 1 Francisco Barros.pdf: 1150670 bytes, checksum: ffca939f0bda301c1c6ca0fdacb118fd (MD5)Made available in DSpace on 2014-11-11T18:05:12Z (GMT).
