Table 1 Experiments 2, 3, experimental design: timing and extent of stepwise salinity reductions (B–F, treatments), beginning from the zoea-IV or megalopa stage, respectively; treatment A (not shown): constant 32‰ (seawater control)

From: Larval salinity tolerance of the South American salt-marsh crab, Neohelice (Chasmagnathus) granulata: physiological constraints to estuarine retention, export and reimmigration
