Abstract: | The horizontal heterogeneity of common zooplankton species in the Keretskaya Guba tidal estuary in the White Sea was studied.
Based on an analysis of a series of simultaneously taken samples and the dispersion index, I
w
= σ2/`(m)]\bar{m} (where σ2 is dispersion and `(m)]\bar{m} is average population number), the existence of two and more levels of aggregation in most of the studied zooplankton species
was found. The formation of patches of 1–20 m was most likely determined by biological causes, while patches some hundreds
of meters long were formed due to the hydrodynamic conditions of the area. |
