In this class, we discuss about the problems our planet is facing with all the wastes people are producing every day.

In predator–prey encounters between fish in which there is physical trauma to the epidermis of the prey, some species release chemical alarm cues into the water. Fish of the same species may perceive these cues and display ...

In this study, I show that mianserin, a chemical with serotonin and adrenoceptor antagonist activities, increases fish vulnerability to a potential predator threat, when prey fish must deal with this threat based on ...

Several fish species trigger defensive behavioral responses when exposed to chemical cues that indicate predation risk. In these situations, physiological adjustments are also necessary to prepare the organism for a defensive ...

The interactions of tropical aquatic fulvic acids (AFA) with chlorine and formation of trihalomethanes were characterized by fluorescence spectroscopy. The aquatic humic substances (AHS) were isolated from a dark-brown ...
