Benthic megafauna and the functioning of macroalgal forests and urchin barrens
Oikos, EarlyView.Two temperate rocky reef food‐web models, representing the trophic diversity of the Mediterranean rocky reef communities, were built for the two stable states: macroalgal forests and barren grounds, which are characterized by opposite amounts of erect macroalgal biomass.

Aquaculture boosts urchin roe production
California Agriculture, 1997 Red sea urchins, with their hedge-hoglike shells and five skeins of edible golden roe, are a gourmet treat, especially in Asia. Each year California divers harvest as many as 25 million pounds of the red sea urchins that many people find delicious and ...

Sea Urchins Predation Facilitates Coral Invasion in a Marine Reserve
PLoS ONE, 2011 Macroalgae is the dominant trophic group on Mediterranean infralittoral rocky bottoms, whereas zooxanthellate corals are extremely rare. However, in recent years, the invasive coral Oculina patagonica appears to be increasing its abundance through ...

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping
Remote Sensing in Ecology and Conservation, EarlyView.Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

Journal of Vinyl and Additive Technology, EarlyView.This study shows that incorporating 5–10 wt.% Posidonia oceanica, with or without micro‐talc, in PBSA preserves thermal stability, modifying crystallization behavior, and maintains good filler dispersion and interfacial adhesion. Mechanical properties are moderately stiffened.
