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

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.

Nephropore Rosette Glands of the Lobster Homarus Americanus: Possible Sources of Urine Pheromones
Paul J. Bushmann,Jelle Atema +1 more
TL;DR: Staining properties and gland morphology suggest that nephropore rosettes are active in males and females, in all molt stages and at all times of the year, and are good candidates for sources of chemical signals.

Screening for induced herbivore resistance in Swedish intertidal seaweeds
TL;DR: The results show that herbivore-induced resistance is present in 7 of 12 of the tested Swedish seaweed species, but that different signals elicit complex responses in the seaweeds.

When intraspecific exceeds interspecific variance : Effects of phytoplankton morphology and growth phase on copepod feeding and fitness
Jeremy D. Long,Mark E. Hay +1 more
TL;DR: When different growth phases (exponential or stationary) or forms (solitary cells or colonies) of a single clone of Phaeocystis globosa were fed to three copepods, grazing, measured indirectly by fecal-pellet production, on different types of P. globosa differed by nearly two orders of magnitude, with differences on this clone sometimes exceeding differences between different phytoplankton species.

TL;DR: In this article, 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.

Loss of waterborne brevetoxins from exposure to phytoplankton competitors
TL;DR: It is suggested that competing phytoplankton species present during K. brevis blooms, and possibly other red tides, could mediate bloom toxicity and therefore ecosystem-level consequences of red tides.
