Community composition of zooplankton exported from a shallow polymictic reservoir linked to wind conditions

Abstract
Zooplankton exported from lentic systems provision lotic systems with easily
captured, consumed, and assimilated prey items. Previous studies have demonstrated
that the community composition of zooplankton exports (CCZE) vary over time,
which introduces temporal differences in lotic resource availability (zooplankton
prey) in downstream habitats. In the study presented here, we monitored variation in
CCZE from a polymictic reservoir outfall in response to physical–chemical and
atmospheric conditions bi-hourly over three different 24-h periods. Community
composition of zooplankton export varied over the course of the day, and exports
were most closely associated with wind directionality. Future studies of temporal
variation in CCZE should incorporate wind conditions, especially in shallow systems
where holomixis occurs frequently. Polymictic reservoirs are becoming increasingly
common as the global pace of small dam construction quickens, making both the
identification of factors influencing CCZE and the impact of zooplankton exports on
local biodiversity and ecosystem function increasingly important to understand.
