The project in a nutshell
The main goal of winter Blitz is to examine global patterns on the dietary energy contained in lake seston and passed on to zooplankton during winter compared to fall and spring. This is a GLEON multi lake survey embracing lakes across the globe, including Lake Geneva.
We hypothesize that herbivorous zooplankton (cladocerans and herbivorous copepods) match the biochemical composition of dietary seston during fall, winter, and spring, indicating active feeding during the presumably non-productive winter season. As a secondary objective we will investigate if carnivorous zooplankton (e.g., cyclopoids) being in a higher trophic position, are able to comparatively produce more offspring during winter than herbivorous zooplankton.
