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 Acidification: The Other CO 2 Problem
TL;DR: The potential for marine organisms to adapt to increasing CO2 and broader implications for ocean ecosystems are not well known; both are high priorities for future research as mentioned in this paper, and both are only imperfect analogs to current conditions.

Larval Dispersal and Marine Population Connectivity
Robert K. Cowen,Su Sponaugle +1 more
TL;DR: Evidence from direct and indirect approaches using geochemical and genetic techniques suggests that populations range from fully open to fully closed and a full understanding of population connectivity has important applications for management and conservation.

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.

Advances in Quantifying Air-Sea Gas Exchange and Environmental Forcing*
TL;DR: It is shown how the use of global variables of environmental forcing that have recently become available and gas exchange relationships that incorporate the main forcing factors will lead to improved estimates of global and regional air-sea gas fluxes based on better fundamental physical, chemical, and biological foundations.

TL;DR: The results imply that humans could be substantially impacting iron and bioavailable iron deposition to ocean regions, but there are large uncertainties in the authors' understanding.

Induced resistance in intertidal macroalgae modifies feeding behaviour of herbivorous snails.
TL;DR: This study is the first to demonstrate that herbivory-induced changes in the tissue chemistry of the brown seaweed Ascophyllum nodosum elicit the same response in the feeding behaviour of the gastropod Littorina obtusata as predicted for herbivorous insects, providing good evidence for the model’s validity across different ecosystems.

TL;DR: The methods used by copepods and rotifers for mate seeking and recognition are compared, the behavioral evidence supporting the existence of chemical cues are described, and experiments describing the biochemical characteristics of the signal molecules are examined.

Competing phytoplankton undermines allelopathy of a bloom-forming dinoflagellate
TL;DR: The results suggest that competitors differ in their responses to phytoplankton allelopathy, with S. costatum exhibiting a previously undescribed method of resistance that may influence community structure and alter bloom dynamics.

Sex Pheromones of the Hair Crab Erimacrus isenbeckii. Part 1: Isolation and Structures of Novel Ceramides
TL;DR: In this paper, the sex pheromones of the brachyuran crab Erimacrus isenbeckii have been isolated by using a unique sponge assay from the water in which postmolt females had been maintained.
