Vertical distribution of benthic marine organisms on rocky coasts of the Fernando de Noronha Archipelago (Brazil)

Qualitative samples of flora and fauna were collected in several points, from the supralittoral fringe down to 30 m, using mainly aqualungs. Species distribution and abundance were determined along four transects, up to 200 m long, in selected places. Samples were taken from 25 x 25 cm quadrats posi...

Description
Summary:Qualitative samples of flora and fauna were collected in several points, from the supralittoral fringe down to 30 m, using mainly aqualungs. Species distribution and abundance were determined along four transects, up to 200 m long, in selected places. Samples were taken from 25 x 25 cm quadrats positioned at fixed intervals along the transects down to a variable depth, depending on algal percentage cover and their substrate. The intertidal zone was populated essentially by molluscs. The subtidal was covered predominantly by macroalgae.
