The comparative effect of the uptake of fresh and degraded detritus of halophytic plants, harvested from salt marches of the Mont Saint-Michel Bay (France), on the growth of a juvenile population of the annelid polychaete N. diversicolor (L.) was studied under experimental conditions in summer 1993. Fresh and degraded detritus of Spartina anglica, Halimione portulacoides and Salicornia europeae...
Three functionally different macrofaunal species (the filter- and/or surface deposit-feeding polychaete Hediste diversicolor, and the suspension-feeding bivalves Mya arenaria and Cerastoderma glaucum) were introduced as single- and two-species treatments into microcosms containing sandy sediment with a natural meiofaunal community. H. diversicolor is a burrowing species building a system of gal...
Citation: Gomiero A, Strafella P, Pellini G, Salvalaggio V and Fabi G (2018) Comparative Effects of Ingested PVC Micro Particles With and Without Adsorbed Benzo(a)pyrene vs. Spiked Sediments on the Cellular and Sub Cellular Processes of the Benthic Organism Hediste diversicolor. Front. Mar. Sci. 5:99. doi: 10.3389/fmars.2018.00099 Comparative Effects of Ingested PVC Micro Particles With and Wit...
Polychaetes have often been utilized as indicator species to investigate the impacts of pollutants, such as heavy metals. The uptake of Cd by the polychaete Nereis diversicolor was determined at varying Ca concentrations and with pre-exposure to Ca ion channel blockers and metabolic inhibitors in simulated sea water over 1 week period. The supply of Ca in simulated sea water inhibited Cd uptake...
Although Beadle a9 early as 1937 suggested that the urine of Nereis diversicolor O. F. Miiller might be of lower concentration than the body fluids when this worm is hyperregulating in low salinities, there has been no direct measurement of urine concentration to support this reasonable idea. Jorgensen & Dales (1957) studied osmotic water uptake and loss in N. diversicolor and calculated that t...
We present here the draft genome sequences for nine strains of Vibrio (V. cyclitrophicus, V. splendidus, V. tasmaniensis, and three unidentified) and one Shewanella strain. Strains were isolated from red (Haliotis rufescens) and white (Haliotis sorenseni) abalone, with and without exposure to "Candidatus Xenohaliotis californiensis," the causative agent of abalone withering syndrome.
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 conditions. Results supported by principal component analysis showed a marked response of the bacterial communities to the oil contamination a...
