A multiple plankton net (Bioness) and a Bongo net were used to collect samples at 35 stations in 1991/92 and 75 stations in 1992/93. Early larval stages (14 species) and

The relevance of environment− biota interactions on deep-sea megafauna in ...

The influence of diel vertical migrations of anchovies on primary production in the
