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

Anchialine Cave Environments: a novel chemosynthetic ecosystem and its ecology
TL;DR: This combined body of research provides the first systematic study into anchialine ecology and has found them to be rich in taxa for comparative study with other chemosynthetic systems, including T. pearsei and S. tulumensis, allowing for a variety of comparative coevolutionary studies.

Behavioural responses to con- and heterospecific alarm cues by an alien and a coexisting native fish
Piotr Kłosiński,Jarosław Kobak,Mateusz Augustyniak,Roman Pawlak,Łukasz Jermacz,Małgorzata Poznańska-Kakareko,Tomasz Kakareko +6 more
TL;DR: In this article, the authors tested intra-and interspecific responses of fish from sympatric populations to damage-released alarm cues (skin extract) in laboratory and found that both species of fish responded to conspecific and heterospecific cues, but their responses were more diverse (changed social distancing among individuals, reduced vertical and horizontal movement).

In situ chemical exploration of underwater ecosystems with microsampling/enrichment device.
TL;DR: In situ solid-phase microextraction (SPME) is introduced as a non-invasive and non-polluting technique for simultaneous underwater sampling and extraction of small molecules and it is envisioned that this approach can offer new opportunities to explore underwater ecosystems dynamics.

Evaluation of the operational conditions in the production and morphology of Chlorella sp.
TL;DR: Applying the 2n-p fractional factorial design concept for the elemental composition of the microalgae and the cellular morphology, it was obtained 44.33% of C, 7.09% of H, 8.53% of N and 0.84% of S for the Chlorella sp.

The effect of newt toxin on an invasive snail
TL;DR: The results suggest that California newts may help limit the spread of P. antipodarum in streams where T. torosa is both able to persist and possess adequate chemical defenses.

Centuries of Human-Driven Change in Salt Marsh Ecosystems
TL;DR: It is concluded that the best way to protect salt marshes and the services they provide is through the integrated approach of ecosystem-based management.

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.
