The Spawning of Arenicola Marina ( L ) . I . the Breeding Season

Observations on the burrowing of Arenicola marina (L.).

The hydrostatic skeleton of Arenicola marina has been investigated in some detail both by Chapman & Newell (1947) and by Wells (1954) and our knowledge of the habits of this species is broadly based on the extensive researches of the latter author (1961). When a new method of continuous pressure recording became available to me I immediately tried it out on Arenicola as an established standard ...

Ventilatory and metabolic responses to hypoxia and sulphide in the lugworm Arenicola marina (L.).

We examined the effects of hypoxia and sulphide levels on the ventilatory activity of Arenicola marina and determined whether ventilation compensates for oxygen deficiency and affects the mode of energy provision. A. marina ventilated intermittently, irrespective of ambient P(O2) and sulphide concentration. The ventilation rate was 28.5+/-16 ml h(-1) g(-1) wet mass during normoxia, but increase...

The Effect of Microplastic on the Uptake of Chemicals by the Lugworm Arenicola marina (L.) under Environmentally Relevant Exposure Conditions

It has been hypothesized that ingestion of microplastic increases exposure of aquatic organisms to hydrophobic contaminants. To date, most laboratory studies investigated chemical transfer from ingested microplastic without taking other exposure pathways into account. Therefore, we studied the effect of polyethylene (PE) microplastic in sediment on PCB uptake by Arenicola marina as a model spec...
