This assumption could at least explain the absence of
observable mating behavior in Cyclestheria.
Acknowledgments
The studies on conchostracans were funded by grants
from the Colombian Institute for Development of
Science and Technology 'Francisco Jose de Caldas'
(COLCIENCIAS) and the Los Andes University. I
am especially indebted to the staff of the Colombian Hydrometeorological Institute (HIMAT) for their
cooperation during several national expeditions. I
thank Dr Denton Belk for his critical and stimulating revision of the manuscript and Trudy Sassaman for
typing and copy editing the final draft.
