The spatial and temporal variations of deep-sea megafaunal assemblages from the western
Mediterranean are analysed in the present paper. The assemblages from two locations of
the Balearic Islands situated 120 km apart were compared using data collected seasonally
on a bathymetric stratum covering the 150–750 m depth range during six bottom-trawl
surveys. The assemblage structure, in terms of species composition, species dominance
and population sizes, was differentially affected by the spatio-temporal variables analysed …
