Effects of population density on the sediment mixing induced by the gallery-diffusor Hediste (Nereis) diversicolor O.F. Müller, 1776 [PDF]

open access: yes, 2006
The aim of this work was to quantify the intensity of sediment mixing induced by the gallery-diffusor (functional bioturbation group) Hediste diversicolor as a function of density, using particles tracers (luminophores).

Molecular and Morphological Phylogenies of Spirorbinae (Serpulidae, Polychaeta, Annelida) and the Evolution of Brooding Modes

open access: yesDiversity
Spirorbinae, a ubiquitous group of marine calcareous tubeworms with a small body size as adults, have a fascinating diversity of brooding modes that form the basis for their taxonomic division into six tribes (traditionally subfamilies): in-tube ...

Short-term effects of CO₂-induced low pH exposure on target gene expression in Platynereis dumerilii [PDF]

open access: yes, 2016
Objective: Increasing atmospheric CO₂ concentration are causing changes to the seawater carbonate chemistry, lowering the pH and we study potential impacts of these changes at the molecular level in a non-calcifying, marine polychaete species Platynereis

Hydrocarbon influence on denitrification in bioturbated Mediterranean coastal sediments [PDF]

open access: yes, 1997
An in situ experiment has been carried out inbioturbated Mediterranean coastal marine sediments (Gulfof Fos) in order to study the influence of hydrocarbons ondenitrification after 1, 4 and 6 months. In theabsence of hydrocarbons in the control sediments,

Influence of the predatory polychaete Nephtys hombergii on the abundance of other polychaetes [PDF]

open access: yesMarine Ecology Progress Series, 1987
Negative relations between abundance of the predatory polychaete Nephtys hombergii and values for biornass and rate of increase in 2 of its prey species, the polychaetes Scoloplos armiger and Heteromastusfiliformis, are evident in long-term (18 yr) data from tidal flats in the westernmost part of the Wadden Sea.

Expression of Distal-less, dachshund, and optomotor blind in Neanthes arenaceodentata (Annelida, Nereididae) does not support homology of appendage-forming mechanisms across the Bilateria [PDF]

open access: yes, 2010
The similarity in the genetic regulation of arthropod and vertebrate appendage formation has been interpreted as the product of a plesiomorphic gene network that was primitively involved in bilaterian appendage development and co-opted to build ...

Effects of low seawater pH on the marine polychaete Platynereis dumerilii [PDF]

open access: yes, 2015
An important priority for any organism is to maintain internal cellular homeostasis including acidbase balance. Yet, the molecular level impacts of changing environmental conditions, such as low pH, remain uncharacterised.

Use of isotope dilution method to predict bioavailability of organic pollutants in historically contaminated sediments. [PDF]

open access: yes, 2014
Many cases of severe environmental contamination arise from historical episodes, where recalcitrant contaminants have resided in the environment for a prolonged time, leading to potentially decreased bioavailability.

Holocene development of submerged keep‐up patch reefs on Bermuda without acroporids: A model of future reef accretion

open access: yesThe Depositional Record, EarlyView.
Bermuda patch reefs development was primarily controlled by massive coral framework construction, and variation in environmental energy, turbidity and bioerosion. These factors shaped the size, diversity and preservation of the framework, leading to a suppressed, steady vertical accretion.
