Marine chemical ecology: chemical signals and cues structure marine populations, communities, and ecosystems.
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

Inhibition effect of green alga on cyanobacteria by the interspecies interactions
J. Q. Chen,R. X. Guo +1 more
TL;DR: The common freshwater green alga Scenedesmus obliquus was selected as the candidate cyanobacteria-control species by its allelopathic effect and the most common cyanobacterial species Microcystis aeruginosa was used as the target organism.

Prompt induction of chemical defenses in the red seaweed Laurencia dendroidea: The role of herbivory and epibiosis
Daniela Bueno Sudatti,Mutue T. Fujii,Silvana Vianna Rodrigues,Alexander Turra,Renato Crespo Pereira +4 more
TL;DR: Higher levels of elatol promoted decreased consumption in tropical red seaweed, demonstrating that seaweed susceptibility is dose-dependent and induction is an important ecological strategy depending on environmental conditions.

Marine invertebrate xenobiotic-activated nuclear receptors: their application as sensor elements in high-throughput bioassays for marine bioactive compounds.
Ingrid Richter,Andrew E. Fidler +1 more
TL;DR: It is speculated that increasing access to marine invertebrate genome sequence data will facilitate the generation of high-throughput bioassays/biosensors of widely differing specificities, but all based on activation of XANR LBDs, which may find application in screening marine extracts for bioactive compounds that could act as drug lead compounds.

Solvent separating secondary metabolites directly from biosynthetic tissue for surface-assisted laser desorption ionisation mass spectrometry.
TL;DR: The use of “on surface” solvent separation directly from mollusc tissue onto nanostructured surfaces for MS analysis, as a mechanism for simplifying data annotation and detecting possible artefacts from compound delocalization during the preparative steps is reported.

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.
