Resumen:
We conducted survivorship and population growth studies with two littoral-benthic cladocerans, Alona rectangula and Macrothrix triserialis, littoral-benthic cladocerans, under low and high food levels (0.5×106 and 2.0×106 Chlorella vulgaris cells ml-1). The net reproductive rate ranged from 13 to 15 offspring/female in the case of A. rectangula and between 19 and 27 for M. triserialis. The generation time was also lower (10 d) for A. rectangula but higher (16-18 d) for M. triserialis. Thus, the growth rates of M. triserialis were around 0.25 d-1 while those of A. rectangula around 0.32. The rates of population increase from the population growth experiments were lower than those from the life table demography studies.
