Growth and survival of Daphnia in epilimnetic and metalimnetic water from oligotrophic lakes: the effects of food and temperature
Freshwater Biology

Abstract
SUMMARY 1. In oligotrophic lakes, phytoplankton and bacteria growing in the deep chlorophyll maximum in the cool metalimnion of lakes often dominate biomass and production, but the importance of this source of food for zooplankton is unknown.
2. During much of the day, Daphnia rosea in two mountain lakes inhabited deep chlorophyll layers where food availability was at least equal to that in the epilimnion.
3. To determine the importance of the two strata (epilimnion and metalimnion) for Daphnia, we used a cross‐classified factorial experiment to measure how epilimnetic and metalimnetic food and temperature (10 and 16 °C) influenced survival, growth and reproduction.
