Repeated flood disturbance enhances rotifer dominance and diversity in a zooplankton community of a small dammed mountain pond
The zooplankton community in a relatively small and mountain pond was studied during the spring growing season. To investigate which factors operate in the community structure, we explored several physical conditions, such as high inflows, and the biotic dynamics of the main zooplankton groups (i.e....
