Expansion and homogeneity of the vertical distribution of zooplankton in a very deep mixed layer

摘要: During stratification over 70% of the zooplankton >100 µm in Gulf Aqaba (Eilat), Red Sea, resided upper 100 m. In course winter mixing, vertical pattern became more homogeneous, reaching an almost complete uniformity when mixing exceeded 500 m depth. The expanded its distribution throughout mixed layer. However, full homogeneity, such as would be expected for a passive tracer and observed phytoplankton, occurred only section Homogeneity zoo- plankton passing through 750 mesh but not larger crustaceans. copepod Pleuromamma indica retained diel migration regardless nocturnal range under conditions. homogeneity could have been reached either by entrainment with water or isotropic swimming animals, both. ecological implications expansion predator-prey relationships particle fluxes are discussed.
