How chemical cues regulate critical aspects of the behavior of marine organisms from bacteria to phytoplankton to benthic invertebrates and water column fishes is reviewed.Abstract:
Chemical cues constitute much of the language of life in the sea. Our understanding of biotic interactions and their effects on marine ecosystems will advance more rapidly if this language is studied and understood. Here, I review how chemical cues regulate critical aspects of the behavior of marine organisms from bacteria to phytoplankton to benthic invertebrates and water column fishes. These chemically mediated interactions strongly affect population structure, community organization, and ecosystem function. Chemical cues determine foraging strategies, feeding choices, commensal associations, selection of mates and habitats, competitive interactions, and transfer of energy and nutrients within and among ecosystems. In numerous cases, the indirect effects of chemical signals on behavior have as much or more effect on community structure and function as the direct effects of consumers and pathogens. Chemical cues are critical for understanding marine systems, but their omnipresence and impact are inadequ...read more

Chemical signatures of multi-species foraging aggregations are attractive to fish
TL;DR: Results indicate that chemical cues collected within the middle of multi-species fish foraging aggregations are attractive to adult reef fish and suggest that chemical signatures associated with foraging aggregation might be important olfactory guides for fish.

Population dynamics and pattern formation in an info-chemical mediated tri-trophic plankton model
TL;DR: In this article, a spatio-temporal prey-predator model of plankton is proposed and the critical conditions for Turing instability are derived; these are necessary and sufficient.

Multiple stressors associated with acid sulfate soil effluent influence mud crab Scylla serrata predation on Sydney rock oysters Saccostrea glomerata
TL;DR: Long-term exposure to acid sulfate soil effluent alters trophic dynamics between predators and prey, which may have consequences for coastal food webs.

Marine Plant-Herbivore Interactions: The Ecology of Chemical Defense
Mark E. Hay,William Fenical +1 more
TL;DR: Although numerous seaweed characteristics can deter some herbivores, the effects of morphology and chemistry have been studied most thoroughly and these types of seaweeds may be considered herbivore tolerant.

Evidence that halogenated furanones from Delisea pulchra inhibit acylated homoserine lactone (AHL)-mediated gene expression by displacing the AHL signal from its receptor protein.

TL;DR: The contention that furanones, at the concentrations produced by the alga, can control bacterial colonization of surfaces by specifically interfering with AHL-mediated gene expression at the level of the LuxR protein is supported.

Marine chemical ecology: what's known and what's next?
TL;DR: This review concludes that relatively unstudied, ontogenetic shifts in concentrations and types of defenses occur in marine species, and patterns of larval chemical defenses appear to provide insights into the evolution of complex life cycles and of differing modes of development among marine invertebrates.
