We quantified within-species variation in the tolerance of the large, lake-dwelling daphnid, Daphnia pulicaria, to toxic cyanobacteria in the diet. Juvenile growth rates on diets consisting of 100% Ankistrodesmus falcatus (a nutritious green alga) or 100% Microcystis aeruginosa (toxic) were compared for D. pulicaria clones isolated from lakes expected to have low and high levels of bloom-formin...

Functional foods include any natural product that presents health-promoting effects, thereby reducing the risk of chronic diseases. Cerrado fruits are considered a source of bioactive substances, mainly phenolic compounds, making them important functional foods. Despite this, the losses of natural vegetation in the Cerrado are progressive. Hence, the knowledge propagation about the importance o...

Two traditional species in the Daphnia pulex group (0. pulex and D. pulicmiu) are not completely reproductively isolated. The microhabitats they dominate are distinct but overlap geographically, and migration between the microhabitats is not uncommon. Their species identity is not fully supported by a recent molecular study. A laboratory experiment shows that Daphnia clones isolated from two po...
