BACKGROUND Chemical cues provide aquatic organisms with sensory information that guides behavioural responses and thus interactions among themselves, each other and the environment. Chemical cues are considered important for predator avoidance, foraging, larval settlement and broadcast spawning in aquatic environments. However, the significance of their(More)
The recent dry phase experienced by the St Lucia estuarine system has led to unprecedented desiccation and hypersaline conditions through most of its surface area. This has changed only recently, at the end of 2011, with the onset of a new wet phase that has already caused a major shift to oligo- and mesohaline conditions. The estuary mouth, however,(More)
Chemical cues released by organisms have the potential to impact the behaviour of species, particularly in aquatic environments. These interactions affect the dynamics of resource utilisation at a small scale. Chemical cues may also be significantly involved in heterospecific competition and in reducing biotic resistance thus facilitating invasion success.(More)
