On some Factors Limiting the Habitat of Arenicola marina

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 ...

Arenicolid behaviors: similarity of Arenicola marina and Abarenicola pacifica

The hydraulic activities of two arenicolid polychaetes, Abarenicola pacifica and Arenicola marina, result in strikingly similar pressure waveforms. The principal hydraulic activities are defecation, burrowing and feeding/ burrow maintenance. Both the duration and magnitudes of the pressures are very similar. The behavioral periodicities of the two species are also quite similar, although burrow...

Arenicola marina extracellular hemoglobin: a new promising blood substitute.

The need to develop a blood substitute is now urgent because of the increasing concern over Europe's BSE outbreak and the worldwide HIV/AIDS epidemic, which have cut blood supplies. Extracellular soluble hemoglobin has long been studied for its possible use as a safe and effective alternative to blood transfusion, but this has met with little success. Clinical trials have revealed undesirable s...

Effects of the bioturbating lugworm Arenicola marina on the structure of benthic protistan communities

Sedimentary coastal ecosystems like the European Wadden Sea in the northeastern Atlantic harbor large populations of burrowing infauna, such as arenicolide polychaetes. These ‘ecosystem engineering’ macrofaunal organisms destabilize sediments by reworking and irrigating them, leading to a reorganization of sediment physicochemical state and bacterial communities. Here, we tested the effects of ...
