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.

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.

Bile Acid Secreted by Male Sea Lamprey That Acts as a Sex Pheromone
Weiming Li,Alexander P. Scott,Michael J. Siefkes,Honggao Yan,Qin Liu,Sang-Seon Yun,Douglas A. Gage +6 more
TL;DR: It is shown that reproductively mature male sea lampreys release a bile acid that acts as a potent sex pheromone, inducing preference and searching behavior in ovulated female lampreys.

Chemical Defense Against Different Marine Herbivores: Are Amphipods Insect Equivalents?
TL;DR: The ability of amphipods to circumvent the chemical defenses of Dictyota, and the fact that the two species of algae most readily consumed by amphipODs were the twospecies least readily consumedBy fish, suggest that predation and herbivory by fishes may be major factors selecting for amphipod that can live on, and eat, seaweeds that are unpalatable to fishes.

Extraordinarily high spider densities on islands: flow of energy from the marine to terrestrial food webs and the absence of predation

TL;DR: This work explicitly connects the marine and terrestrial systems to show that insular food webs represent one endpoint of the marine web, and describes two conduits for marine energy entering these islands: shore drift and seabird colonies.

Food and Shelter as Determinants of Food Choice by an Herbivorous Marine Amphipod
J. Emmett Duffy,Mark E. Hay +1 more
TL;DR: Variance in survivorship, and related measures, among sibling groups of amphipods suggested that this amphipod population possessed heritable variation for performance on the different seaweed species, and the lack of any consistent relationship between host-plant use in the field and either feeding preference or diet value, suggests that A. longimana may be strongly constrained by requirements for shelter from predation.
