A rotiferan version of the punishment of Sisyphus?

Abstract

In March 2017, we joined a multi-disciplinary expedition on Lake Onego, in the Russian Karelia, with the primary goal to investigate zooplankton strategies to survive deep winter under ice. We intended to focus on the large zooplankters, i.e. crustaceans of tenths to a few mm of body length, through sampling by horizontal and vertical trawls using nets of relatively large mesh-size. Delays in the delivery of sampling gear compelled us to opt, at the last minute, for a much-smaller mesh size net for the horizontal trawls underneath ice.
