The amine serotonin has been suggested to play a key role in aggression in many species
of animals, including man. Precisely how the amine functions, however, has remained a …

The interdisciplinary field of marine chemical ecology is an expanding and dynamic science.
It is no surprise that the breadth of marine organisms studied expanded in concert with …

Animals commonly modify their behavior in the presence of a conspecific or in response to
signals. This is particularly true in the context of aggressive exchanges, which animals use …

Chemical communication is a widespread phenomenon in aquatic animals but is difficult to
investigate because the signals are not visible. Here, we present the results of a study into …

To investigate the role of certain neurohormones in agonistic behaviour, fights were staged
between pairs of size-matched male shore crabs Carcinus maenas, and blood samples …

Although many crustaceans produce sounds, their hearing abilities and mechanisms are
poorly understood, leaving uncertainties regarding whether or how these animals use sound …

The present study investigated both the effects of cadmium on the social interactions of
rainbow trout and the differential accumulation of waterborne cadmium among social ranks …

Gastropods represent a challenge in the understanding of alarm signalling. We studied
predator avoidance (climbing behaviour) of the marine snail Tegula funebralis in laboratory …

Chemicals carried in the urine are a rich source of information about the identity, sex,
aggressive motivation, and other attributes of an animal. In agonistic interactions, animals …

Decapod crustaceans, like many other animals, engage in agonistic behaviors that enhance
their ability to compete for resources with conspecifics. These agonistic behaviors include …
