Abstract
Several observations and model calculations suggest that chemically mediated interactions can structure
planktonic food webs. However, only recently have
improvements in chemical methods, coupled with ecological
assays, led to the characterization of chemical
cues that affect the behaviour and/or physiology of
planktonic organisms. We are currently beginning to
elucidate if or how chemical signals can directly affect
the interactions between species and even shape complex
community structures in aquatic systems. Here, we
highlight recent research on the nature and action of
chemical signals in the pelagic marine and freshwater
environments, with an emphasis on kairomones and
defence metabolites.
