dc.descriptionIn this work we analyzed the depth-distribution, at noon and midnight, of three zooplankton populations which are common inhabitants of lakes from central Chile and coexist in lake El Plateado. The species were Tumeodiaptomus diabolicus, Diaphanosoma chilense and Bosmina longirostris. Also, we analyzed the association between the depth-specific abundances of the groups and the depth-specific temperature and oxygen values during the sampling period. Our results show that: (1) the three population exhibited diel vertical migration during part of the year; (2) T. diabolicus and D. chilense exhibited the normal pattern of vertical migration, and B. longirostris presented both the normal and the reverse pattern; (3) for all species and most dates, zooplankters experience significant decreases in oxygen exposure as a consequence of downward migration. Temperature costs are less important but present in T. diabolicus and D. chilense during part of the year
