Resumen:
AbstractConochilus hippocrepis colonies were analysed in relation to the presence and size of the predaceous calanoidcopepod Parabroteas sarsi. Conochilus colonies increase in size throughout the season from May to August andthen disappear from the lake. Simultaneously, Parabroteas developed from CI to CV and adults. We observed thatwhen the predaceous copepod begins to prey on Conochilus, colony size increases in relation to maxilliped lengthof the predator. Our results show that the increasing size of the colony of Conochilus is an effective defense againstParabroteas predation.
