Diel vertical and horizontal distribution of crustacean zooplankton and young of the year fish in a sub-alpine lake: an approach based on high frequency sampling

Abstract

The spatial distribution of crustacean zooplankton in lacustrine environments is affected by multiple physicochemical and biological processes, the nature and the relative importance of which vary among ecosystems and at different spatial and temporal scales Fish predation has been cited as one of the most important factors influencing zooplankton community structure To counteract fish predation, zooplankton have developed avoidance strategies, such as diurnal horizontal migration (DHM) in weedy littoral zones (Davies,
