Global conservation outcomes depend on marine protected areas with five key features
The results show that global conservation targets based on area alone will not optimize protection of marine biodiversity, and more emphasis is needed on better MPA design, durable management and compliance to ensure that MPAs achieve their desired conservation value.
Inhibition of coral recruitment by macroalgae and cyanobacteria

Evidence is provided that algae and cyanobacteria use tactics beyond space occupation to inhibit coral recruitment, thereby perpetuating reduced coral cover and limiting coral community recovery on reefs experiencing phase shifts or tempo- rary algal blooms.
Integrating abundance and functional traits reveals new global hotspots of fish diversity
The findings suggest that the contribution of species diversity to a range of ecosystem functions varies over large scales, and imply that in tropical regions, which have higher numbers of species, each species contributes proportionally less to community-level ecological processes on average than species in temperate regions.

New evidence is provided on the population structure of this commercial species, predicting a healthy stock of this sea urchin on the Mediterranean and Atlantic coasts, and finding significant genetic differentiation between the two basins.

The process of silica deposition in sponges at the molecular and cellular levels, as well as the biological and ecological functions of spicules and skeletons are reviewed.
Biogeography of sponge chemical ecology: comparisons of tropical and temperate defenses
This study provides the first experimental test of latitudinal differences in the effectiveness of sponge chemical defenses and suggests a recurrent selection for chemical defenses in sponges as a general life-history strategy.
Silica deposition in Demosponges: spiculogenesis in Crambe crambe
Transmission electron-microscopy images coupled with dispersive X-ray analysis of the species Crambe crambe have provided information on the process of silica deposition in Demosponges and Si deposition starts at regularly distributed sites along the axial filament.
Experimental evidence of chemical deterrence against multiple herbivores in the seagrass Posidonia oceanica .
The results represent the first experimental evidence for seagrass chemical deterrence against a range of consumers, and emphasise the potential importance of chemically mediated interactions between seagRass and herbivores.
Variation in multiple traits of vegetative and reproductive seagrass tissues influences plant–herbivore interactions
It is experimentally demonstrated that leaf structural defences are the primary factor in determining urchin feeding preferences, indicating that multiple mechanisms of defence to herbivory may coexist in seagrasses.
Location of toxicity within the Mediterranean sponge Crambe crambe (Demospongiae: Poecilosclerida)
Results point to spherulous cells being responsible for the storage (and possibly production) of the toxic compounds in C. crambe, which is concentrated in the sponge periphery.
