TLDR
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

Replenishment of fish populations is threatened by ocean acidification
Philip L. Munday,Danielle L. Dixson,Mark I. McCormick,Mark G. Meekan,Maud C. O. Ferrari,Douglas P. Chivers +5 more
TL;DR: Levels of dissolved CO2 predicted to occur in the ocean this century alter the behavior of larval fish and dramatically decrease their survival during recruitment to adult populations and have far-reaching consequences for the sustainability of fish populations.

TL;DR: How the vertical exchanges of tracers associated with mesoscale eddies may answer the issues raised by biogeochemical studies and inspire future directions is discussed.

Algal chemodiversity and bioactivity: sources of natural variability and implications for commercial application.
TL;DR: The taxonomic, ecological and chemical diversity between, and within, different algal groups and the implications for commercial utilisation of algae from natural populations are outlined and the biochemical diversity and complexity of commercially important types of compounds and their environmental and developmental control are addressed.

Pheromones and Animal Behavior: Chemical Signals and Signatures
TL;DR: This extensively revised and expanded book offers a thorough exploration of the evolutionary and behavioral contexts of chemical communication along with a detailed introduction to the molecular and neural basis of signal perception through olfaction.
Journal ArticleDOI
Chemical interactions between marine macroalgae and bacteria
TL;DR: There is a strong need to investigate the bacterial communities living on different coexisting macroalgae using new technologies, but also to investigation the production, localization and secretion of the biological active metabolites involved in those possible ecological interactions.

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.
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.
