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

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.

Sensitivity to dimethyl sulphide suggests a mechanism for olfactory navigation by seabirds
TL;DR: The first physiological demonstration that an Antarctic seabird can detect DMS at biogenic levels is presented, and it is shown that birds can use DMS as an orientation cue in a non-foraging context within a concentration range that they might naturally encounter over the ocean.

TL;DR: The results of this study indicate that a wide range of invertebrates use chemical defense to protect their early stage embryos against bacterial infection.

Clamming up: environmental forces diminish the perceptive ability of bivalve prey
TL;DR: The results suggest that prey perception of predators can be altered by physical forces, and predator-induced alterations in feeding reduce clam mortality in the field.

Seaweed-herbivore-predator interactions: host-plant specialization reduces predation on small herbivores
TL;DR: Interactions among the chemically-defended seaweed Chlorodesmis fastigiata, herbivores specialized on this alga, and potential predators of these Herbivores on Australia's Great Barrier Reef suggest that escape from and deterrence of predation may be a dominant factor selecting for specialization among these herbivore.
