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

Ocean climate impacts on the primary and secondary metabolites of a muricid mollusc
TL;DR: In this paper, the authors investigated differences in the lipid content of Dicathais orbita exposed to current and predicted future climate change scenarios, and found that the fatty acid composition is dominated by polyunsaturated fatty acids (PUFA 52%) with an n-3:6 fatty acid ratio of almost 2.

Grazing results in mobilization of spherulous cells and re-allocation of secondary metabolites to the surface in the sponge Aplysina aerophoba
TL;DR: The sponge has not evolved a specific response to this specialist predator, but rather relies on rapid regeneration and flexible allocation of constitutive defences.

Bloom Formation and Turing Patterns in an Infochemical Mediated Multitrophic Plankton Model
TL;DR: A two-species predator–prey plankton model is studied, where the grazing pressure of microzooplankton on phytoplankton is controlled through external infochemical mediated predation.

Marine Plant-Herbivore Interactions: The Ecology of Chemical Defense

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.
Mike Manefield,Rocky de Nys,Kumar Naresh,Read Roger,Michael Givskov,Steinberg Peter,Staffan Kjelleberg +6 more
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.
