The segmental musculature of Nereis diversicolor OF Müller is described. The musculature
of Nereis irrorata (Malmgren), Nereis fucata (Savigny) and Neanthes virens (Sars) is
essentially similar but comparison with Perinereis cultrifera (Grube) shows that, at least as …

THE Severn Estuary and Bristol Channel together form the largest inlet in the coastline of the
British Isles and the largest estuarine system (Map 1). The area has long been noted for its
spectacular tidal range (the largest in Europe), extensive shores and muddy water. The …

The body form of Aphrodite is attributed to its exploitation of the nereid creeping mechanism.
It employs a fast stepping pattern, individual limb movements being extension and retraction
of the neuropodium with coordinated chaetal movement. The downward and backward …

Until recently, the most detailed and widely quoted account of the life cycle and reproductive
biology of Nereis diversicolor OF Müller was that of Dales (1950; 1951) for a population in
the Thames Estuary followed for a single season. The study combined a periodic analysis of …

The political problems which emerged in Estonia towards the end of the period of Soviet rule
have been widely discussed in academic literature, together with descriptions of the deep
structural problems believed to have contributed to ethnic mobilisation. Despite rigorous …

Nereid polychaetes are among the most abundant worms in the estuaries of north-western
Europe. Like most other estuarine macrofauna, they have their origins in marine conditions
and the colonisation of estuaries has presented special challenges, both physiological and …

Industrialisation facilitates social and economic change and its role in modifying population
patterns via the process of urbanisation is well documented. The socially selective nature of
population redistribution is widely recognised, but in multi-ethnic states this redistribution of …

The vertical distribution of common species of macroalgae and fauna on rocky shores
extending through the length of the estuary is described. In the west, the shores are fully
marine and exposed to Atlantic waves. In an eastward direction, greater shelter and an …

Abstract In the Severn Estuary and Bristol Channel, a multivariate analysis indicated eight
groupings of macrobenthic fauna, each associated with a different physical habitat. Samples
were faunistically impoverished, especially in sublittoral areas, but greater species richness …
