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.

Salmon and alder as nitrogen sources to riparian forests in a boreal Alaskan watershed
TL;DR: Analysis of riparian vegetation in a boreal Alaskan watershed indicates that trees and shrubs near spawning streams derive ~24–26% of their foliar nitrogen from salmon, which appears to be less important to riparian ecosystems where symbiotic N fixation by alder is prevalent.

The ecological and evolutionary consequences of sperm chemoattraction
TL;DR: Experimental evidence that sperm chemoattraction directly affects the magnitude of fertilization success is provided and it is shown that attractant release by means of diffusion effectively doubles the target size of red abalone eggs, which in turn significantly increases fertilizationsuccess.

Ecological Perspectives on Marine Natural Product Biosynthesis
TL;DR: Compilations of marine structures reveal that by 1993 nearly 7000 different marine structures had been documented; these metabolites represent all the major structural classes of natural products, including terpenes, alkaloids, polyketide, terpene, and alkaloid families, as well as compounds of mixed biosynthesis.

Trophic cascades in rocky shore tide pools: distinguishing lethal and nonlethal effects

TL;DR: It is shown that the mere presence of predator risk cues can initiate a trophic cascade in rocky shore tide pools, and it is found that perceived predation risk reduced snail density as much as the direct predation treatment, showing that green crab predation was not an important factor regulating local snail density.
