“…Predator cues can also be but do not have to be associated to foraging activities (Mitchell et al, 2017). While there are numerous reviews on alarm cues (Hazlett, 2011) some with the special focus on fish (Døving and Lastein, 2009; Lastein et al, 2015; Wisenden, 2015), predator specific cues are less well-reviewed and will therefore be the focus here.…”

“…In the classical and broad sense kairomones are defined as interspecific chemical cues perceived by a benefiting prey to reduce the negative impact of a natural enemy (Ruther et al, 2002). As there are already numerous, valuable, and detailed reviews on the perception of chemical alarm pheromones (Sorensen and Stacey, 2004; Døving and Lastein, 2009; Dew et al, 2014; Ahuja et al, 2015; Lastein et al, 2015; Wisenden, 2015), these and the perceptive mechanisms will not be reviewed here.…”

Ecological communities are organized in trophic levels that share manifold interactions forming complex food webs. Infochemicals can further modify these interactions, e.g., by inducing defenses in prey. The micro-crustacean Daphnia is able to respond to predator-specific chemical cues indicating an increased predation risk. Daphnia shows plastic responses by adapting its morphology, behavior, and physiology, increasing organism, and population fitness. This stabilizes community structures. This review will describe the progress that has been made in understanding the high degree of plasticity observed in the model crustacean Daphnia. I summarize current knowledge on the processes of predator detection, ranging from the nature of biologically active chemical cues to the underlying neurophysiological mechanisms. With this, I aim to provide a comprehensive overview on the molecular mechanisms of ad hoc environmental phenotypic adaptation. In times of climate change and pollution understanding information transfer in aquatic systems is valuable as it will allow us to predict whether and how community structures are being affected.

“…Las neuronas secundarias median información al telencéfalo a través de sus axones que forman los tractos olfatorios. Todas estas estructuras se encuentran en la parte anterior del cerebro, con neuronas sensoriales frecuentemente reunidas en una roseta que se localiza frente a los ojos y cerca de la punta de la nariz (Figura 2) (Lastein et al, 2014).…”
