Living deep-sea benthic foraminifera from the Cap de Creus Canyon (western Mediterranean): Faunal-geochemical interactions

► We sampled living benthic foraminifera from Cap de Creus Canyon and adjacent slope (Mediterranean). ► Foraminiferal faunas were compared with pore-water chemistry and organic-matter availability. ► Canyon faunas appeared better developed than adjacent slope faunas at similar water-depths. ► Standing stocks and assemblages were controlled by food supply and food quality. ► Redox chemistry appeared to play a secondary role by influencing species diversity.
