Unravelling Hidden Trophic Interactions Among Sea Urchin Juveniles and Macroinvertebrates by DNA Amplification. [PDF]
Mol EcolABSTRACT Rocky reefs may shift between two distinct stable states: productive algal forests, characterised by high abundance and biodiversity of macrofauna, and impoverished barrens, dominated by overgrazing sea urchins. Barren states may persist despite the recovery of adult sea urchin predators, suggesting additional stabilising mechanisms.

Lethaia, EarlyView., 2021 Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Macroid Formation in Salmacina stellaebayensis n. sp. From Mauritania's Baie de l'Étoile With New Insights on Mitogenome Evolution in Serpulidae (Annelida) [PDF]
Ecol EvolWe describe Salmacina stellaebayensis n. sp. from Mauritania's Baie de l'Étoile and provide the first complete mitochondrial genome for the genus Salmacina. The species forms distinctive macroid colonies in Cymodocea nodosa seagrass meadows, offering new insights into serpulid life history and habitat specialization.

Distribution of Polychaeta in soft-bottoms of a Galician Ria (NW Spain)
Scientia Marina, 2008 Macrobenthic polychaete distributions were studied along the soft-bottoms of the Ensenada de San Simón (Galicia, NW Spain). Results suggest that the distribution and abundance of polychaetes in the inlet were highly dependent on depth, sediment ...
