Weekend #Plankton #Factoid
Cladoceran freshwater #zooplankton are notoriously plastic in that they are capable of wide range of traits without need for sexual reproduction. A new study has found #Daphnia perhaps don't need natural selection. They have high year to year #genetic variation, even under constant environmental conditions, which gives them built-in success across a range of environments, and likely explains their cosmopolitan distribution. #science
