The present climate warming exerts significant effects on coastal marine communities. These effects include species ranges moving poleward, declining numbers at the warm edge and increasing numbers at the cold edge of the distribution areas. We descr

The Brey model to calculate secondary production from data on biomass and mean individual weight is widely used, but so far it has not been tested for communities in which one or a few species dominate. On the base of a long-term (tens of years) data

To investigate the relationship between stock size and production of an entire feeding guild, and in particular to find out whether this relationship is dome-shaped (showing an optimal abundance for production), we used a 40 yr data set of the 3 most

Understanding possible effects of cockle dredging on bivalve dynamics should include studies of the influence of cockle abundance on bivalve recruitment and of effects of fishery on survival of recruits present at the time of fishing and on future re

In the Wadden Sea, annual recruitmentin the major bivalve species is mostly successful insummers following severe winters, whereas it usuallyfails after mild winters. On the basis of a 40 yr data series,we corroborated this relationship between winte

Results are reported of a long-term and multi-station monitoring study in the western Wadden Sea on numerical densities, biomass, individual weights, and production of populations of the newly (late 1970s) introduced bivalve Ensis directus. Data are

In suspension-feeding bivalves, growth rates generally remain at a high level over abroad range of numerical densities. However, data series on growth and production that cover awide density range in a natural marine benthic system appear to be scarc

We challenge a conclusion reached by Barnes & de Villiers in a paper that was recently published in this Journal, viz that certain benthic invertebrates occur in lower abundances in lagoons than in intertidal soft-bottom areas and that this differenc

Two bivalve molluscs, Tellina tenuis and Abra tenuis , apparently susceptible to low winter temperatures, were studied on the intertidal Balgzand in the western Wadden Sea during a 30-y monitoring programme. Both species live in the Wadden Sea on the
