First European record of the invasive brackish water clam Rangia cuneata (G.B. Sowerby I, 1831) (Mollusca: Bivalvia)
Description :
A population of Rangia cuneata (G.B. Sowerby I, 1831), an estuarine bivalve, has been recorded in the harbour of Antwerp, Belgium. This species is new to the European brackish water fauna. After initially finding only a few small individuals in August 2005, R. cuneata was encountered f...

Translation of biological and sedimentological point data towards habitat suitability maps of biological communities and EUNIS level 5 maps. Part 1: From point data towards full coverage habitat suitability maps of macrobenthic communities
Description :
If full coverage maps of the physical habitat are available and if the relationships between the physical and the biological habitat are known, it is possible to create a full coverage map of the biological habitat. Predictive modelling or the prediction of physical and biological information in are...

Floating seaweed and the influences of temperature, grazing and clump size on raft longevity: a microcosm study
Description :
Laboratory experiments were conducted to evaluate the longevity, and consequently also the rafting capacity of the brown seaweeds Fucus vesiculosus and Ascophyllum nodosum. The seaweed degradation process and the activity of the grazer Idotea baltica were strongly influenced by ...

Changes in macrofaunal assemblage structure along a morphodynamic sandy beach gradient in the eastern tropical Pacific
Description :
The macrofauna of seven beaches along the coast of Ecuador, in the tropical part of the Eastern Pacific, was sampled along transects. The beaches covered the entire range of beach types that occur in this part of the continent. The aim of the study was to identify the relation between morphodynamic ...

Size distribution of the surfing gastropod Olivella semistriata along a cross-shore gradient in an Ecuadorian sandy beach
Description :
The gastropod Olivella semistriata is by far the most dominant taxon on mesotidal, intermediate sandy beaches in Ecuador. Its surfing behaviour, in which the snails follow the swash with the tide, makes it very difficult to determine the distribution pattern of this species. In this paper, tr...

Is the burrowing performance of a sandy beach surfing gastropod limiting for its macroscale distribution?
Description :
The size-specific burrowing capacity of Olivella semistriata, an extremely abundant surfing gastropod of exposed sandy beaches in the tropical East Pacific, was investigated in terms of sediment grain size. For all investigated sand classes, there was a significant increase in burial time wit...

Can sandy beach molluscs show an endogenously controlled circatidal migrating behaviour? Hints from a swash rig experiment
Description :
Many macrofaunal species inhabiting exposed sandy beaches are dependent on the swash for their nutrition and for migration and are highly adapted to the harsh physical conditions of the swash. The most important physical factors that determine the distribution and behaviour of swash related fauna, n...

Surfing on sandy beaches: an efficient strategy to flourish in a highly dynamic environment?
Description :
The gastropod Olivella semistriata is a dominant surfer on exposed, intermediate beaches in the tropical part of the East-Pacific. The impact of the swash dynamics on the feeding behaviour of the species was studied in order to improve the understanding of the swash zonation pattern of O. ...

Understanding the life of a sandy beach polychaete of functional importance - Scolelepis squamata (Polychaeta: Spionidae) on Belgian sandy beaches (northeastern Atlantic, North Sea)
Description :
The cosmopolitan sandy beach polychaete Scolelepis squamata constitutes an important food resource for juvenile flatfish and wading birds in the northeastern Atlantic, thus playing an important role in sandy beach ecosystem functioning. However, its population dynamics and life history in this...

The ecological impact of beach nourishment and the restrained habitat of key species: experimental insights and field data
Description :
Nowadays, beach nourishment is widely considered as a better alternative than the construction of hard structures to protect a coast against detrimental erosive effects, both from an ecological as from an engineering perspective. Most studies conducted on the ecological impact of beach nourishment a...
