Bacteria can comprise a large fraction of seston in aquatic ecosystems and can therefore significantly contribute to diets of filter-feeding zooplankton. To assess the effect of three heterotrophic bacteria (Flavobacterium sp., Pseudomonas sp. and Escherichia coli) on survival, growth and egg production of juvenile Daphnia magna during six-day growth experiments, five ratios of bacteria ...

Daphnia é um género de crustáceos da ordem Cladocera, normalmente chamada de pulga de água ou dáfnia. Devido à forma como nada impulsionada por duas antenas situadas no cimo da sua cabeça (segunda antena), a dáfnia parece pular dentro de água como pulam as pulgas terrestres. [ 1]The development of structural defences, such as the fortification of shells or exoskeletons, is a widespread strategy to reduce predator attack efficiency. In unpredictable environments these defences may be more pronounced in the presence of a predator. The cladoceran Daphnia magna (Crustacea: Branchiopoda: Cladocera) has been shown to develop a bulky morphotype as an effective inducible ...Daphnia magna (water flea) in conditions of freshwater, 20-22 °C, pH 7.6-7.7, exposure to a concentration of 340 000 μg l −1 for 24 h resulted in intoxication and immobilization.

As both species reduced the amount of Bd detected in water ...Daphnia are also known to migrate toward or away from the banks of ponds or lakes. Again, the most likely explanation for this behavior is predator avoidance. Certain species of Daphnia, e.g., D. magna, can be observed clinging occasionally to plants or other substrate. Furthermore, they may browse over the surface substrates to pick up small ...Daphnia magna were exposed to two pesticides in the presence or absence of microplastics (300 000 particles ml −1 1 µm polystyrene spheres) and to microplastics alone.
