Spatial oxygen heterogeneity in a Hediste diversicolor irrigated burrow [PDF]

open access: yes, 2011
The heterogeneity of oxygen distribution in a Hediste diversicolor burrow environment was investigated in a laboratory experiment using a 6-mm thick tank equipped with oxygen planar optodes. The twodimensional oxygen distribution in a complete burrow was

Changes in seagrass polychaete assemblages after invasion by Caulerpa racemosa var. cylindracea (Chlorophyta: Caulerpales): community structure, trophic guilds and taxonomic distinctness

open access: yesScientia Marina, 2010
A two-year study focusing on the associated polychaete assemblages revealed that the degradation of the Posidonia oceanica seagrass meadows, together with the colonisation of rhizomes by invasive Caulerpa racemosa in the Balearic Islands, have produced ...

Explorations on the ecological role of toxin secretion and delivery in jawless predatory Polychaeta

open access: yesScientific Reports, 2018
Motivated by biotechnological prospects, there is increasing evidence that we may just be scraping the tip of the iceberg of poisonous marine invertebrates, among which the Polychaeta are promising candidates for bioprospecting.
