First record of Chaetacanthus magnificus (Polychaeta: Polynoidae) from the northeast coast of Brazil, with an overview of its taxonomic history

open access: yesCuadernos de investigación UNED, 2013
Polynoidae is a diverse group of polychaetes known as scale-worms, found in different marine regions. However this rich family is little studied in Brazil, especially along the northeastern coast of the country.

Imaging Oxygen Distribution in Marine Sediments. The Importance of Bioturbation and Sediment Heterogeneity [PDF]

open access: yes, 2008
The influence of sediment oxygen heterogeneity, due to bioturbation, on diffusive oxygen flux was investigated. Laboratory experiments were carried out with 3 macrobenthic species presenting different bioturbation behaviour patterns:the polychaetes ...

Shell accumulation on seabed due to suspended coastal oyster farming and effects on burrowing capacity of the polychaete Perinereis aibuhitensis

open access: yesFrontiers in Marine Science, 2023
Mariculture of bivalves (e.g., mussels, scallops, and oysters) is developing rapidly in coastal waters. This process releases shell debris that can accumulate on the seabed under farms.

Will improving wastewater treatment impact shorebirds? Effects of sewage discharges on estuarine invertebrates and birds [PDF]

open access: yes, 2012
Human communities often discharge wastewaters into estuaries, influencing their organic and pollutant loading, benthic community and trophic structure.

Polytraits : a database on biological traits of marine polychaetes [PDF]

open access: yes, 2014
The study of ecosystem functioning – the role which organisms play in an ecosystem – is becoming increasingly important in marine ecological research. The functional structure of a community can be represented by a set of functional traits assigned to ...

Effects of ocean acidification on invertebrate settlement at volcanic CO2 vents [PDF]

open access: yes, 2010
We present the first study of the effects of ocean acidification on settlement of benthic invertebrates and microfauna. Artificial collectors were placed for 1 month along pH gradients at CO2 vents off Ischia (Tyrrhenian Sea, Italy).

Impacts of in vivo and in vitro exposures to tamoxifen: comparative effects on human cells and marine organisms [PDF]

open access: yes, 2019
Tamoxifen (TAM) is a first generation-SERM administered for hormone receptor-positive (HER+) breast cancer in both pre- and post-menopausal patients and may undergo metabolic activation in organisms that share similar receptors and thus face comparable ...

New genus, three new species and new records of Herpyllobiidae Hansen, 1892 (Crustacea, Copepoda) parasites of polychaetes from Antarctica [PDF]

open access: yes, 2006
During the Antarctic Polarstern cruises ANT XIX/3 (ANDEEP-I), XIX/5 (LAMPOS), and XXI/2 (BENDEX) new material of symbiotic copepods associated with polynoid polychaetes was collected.

Temperature-Modulated Expression of Allometric Respiration Strategies Supports a Metabolic Scaling Rule

open access: yesFrontiers in Marine Science, 2017
A model based on the mass-specific oxygen consumption rate of the tolerant polychaete, Capitella telata, related meaningfully to a novel metabolic scaling rule as applied to the infaunal size spectrum. Depending on temperature, C.

Influence of bioturbation by the polychaete Nereis diversicolor on the structure of bacterial communities in oil contaminated coastal sediments [PDF]

open access: yes, 2007
Patterns of change in the structure of bacterial communities monitored by ribosomal intergenic spacer analysis (RISA) in oil contaminated sediments inhabited or not by the marine polychaete Nereis diversicolor were studied during 45 days under laboratory
