Abstract | Life-table experiments were performed with two strains of Cylindrospermopsis raciborskii, a saxitoxin-
producing strain (T3) and a non-saxitoxin-producing strain (NPLP-1) combined with the green algae
Ankistrodesmus falcatus, aiming to detect effects on the reproduction of three cladocerans species:
Daphnia pulex, Daphnia gessneri and Moina micrura. Survivorship, age at first reproduction, clutch size
and population growth rate during 12–15 days were recorded. Cladocerans showed different
susceptibility to saxitoxin-producing strain (T3), with D. pulex and M. micrura being negatively
affected, followed by and D. gessneri, which did not show any decrease in fitness and performed even
better than the controls with this strain. A reverse response was found in experiments with the nonsaxitoxin-producing strain (NPLP-1): while D. pulex and M. micrura had an increase, D. gessneri showed a
significant decrease in fitness, suggesting that this strain may produce some bioactive compound. The
contrasting responses of the cladoceran species to saxitoxins and non-saxitoxin-producing strains of C.
raciborskii suggest that the presence of this cyanobacterium may be a selective factor in determining the
composition of zooplankton communities. | pt_BR |
