Effects of a vertebrate predator (Poecillia reticulata) presence on Ceriodaphnia cornuta (Cladocera: Crustacea) in laboratory conditions
Aim: To detect the induction of morphological and populational alterations on Ceriodaphnia cornuta concerning cyclomorphosis and population dynamic parameters as densities, fecundity rates, juveniles percentage, males presence and ephippia presence in the presence of predators; Methods: Two experiments were performed: Experiments with fishes fed on Ceriodaphnia cornuta – Experiment 1 – and “Fis...
متن کاملExperiments on the influence of Chaoborus brasiliensis Theobald, 1901 (Diptera: Chaoboridae) on the diel vertical migration of microcrustaceans from Lake Monte Alegre, Brazil.
The aim of this work was to evaluate whether diel vertical migration of microcrustaceans from Lake Monte Alegre is related to invertebrate predators, namely larvae of Chaoborus brasiliensis. The hypothesis tested in the experiments was that the migratory behaviour of prey would depend on physical contact with Chaoborus brasiliensis larvae or with kairomones released by them. Two experiments wer...
متن کاملComposition and abundance of zooplankton in the limnetic zone of seven reservoirs of the Paranapanema River, Brazil.
The species composition and abundance of the zooplankton community of seven reservoirs of the Paranapanema River, located between 22 degrees 37'-23 degrees 11'S and 48 degrees 55'-50 degrees 32'W, were analysed over four periods, in the year of 1979. The zooplankton community was composed of 76 species of Rotifera, 26 species of Cladocera and 7 species of Copepoda. For a large part of the perio...
متن کاملWater mite predation on zooplankton of a tropical lake.
Water mite (Krendowskia sp.) predation on zooplanktonic species from Lake Monte Alegre (São Paulo State, Brazil) was tested in laboratory experiments. One cladoceran, Daphnia gessneri, two copepods, Tropocyclops prasinus and Thermocyclops decipiens, and Chaoborus larvae III and IV were supplied as prey to adult mites. The cladoceran Ceriodaphnia cornuta was used in the experiment with mite nymp...
متن کاملMolecular approach to identify sibling species of the Ceriodaphnia cornuta complex (Cladocera: Daphniidae) from Australia with notes on the continental endemism of this group.
Taxonomy of the genus Ceriodaphnia Dana, 1853 (Cladocera: Daphniidae) has been uncertain for a long time, the species richness was often underestimated due to (1) a morphological similarity among the species and (2) their great morphological inter- and intra- populational variability. Support for this conclusion comes from the first analysis of three molecular markers for Australian representat...
