Sabellariaspinulosa reef: a scoring system for evaluating ‘reefiness’ in the context of the Habitats Directive‘Reefs’ are listed under Annex I of the Habitats Directive as a marine habitat to be protected by the designation of Special Areas of Conservation. Crucially for the implementation of the Directive, the distinction between what is considered as ‘reef’ and what is not is imprecise, particularly in relation to colonies of the tube-building polychaete Sabellaria spinulosa...

Dietary lipid changes during herbivory and coprophagy by the marine invertebrate Nereis diversicolorChanges in dietary lipids (fatty acids, sterols and fatty alcohols) during herbivory and coprophagy by the annelid worm Hediste (Nereis) diversicolor (O.F. Müller) were modelled in laboratory feeding experiments. The dinoflagellate Scrippsiella trochoidea (Stein) was used as the food in herbivory; faeces from the crustacean ...

Shallow-Water Zonation of Sea-Loch Benthos and Its Relation to Hydrographic and Other Physical FeaturesSurveys of marine benthic distributions are usually performed by sampling from a vessel capable of handling the heavy sampling devices necessary. Because of the inability of such vessels to work in very shallow water or close to the shore the area just beyond the intertidal zone is inaccessible to investigation except by a special vessel (e.g. Mclntyre & Eleftheriou, 1968) or by using ... ...

Observations on luminescence in pelagic animalsLuminescence is very common among marine animals, and many species possess highly developed photophores or light-emitting organs. It is probable, therefore, that luminescence plays an important part in the economy of their lives. A few determinations of the spectral composition and intensity of light emitted by marine animals are available (Coblentz & Hughes, 1926; Eymers & van Sch... ...

Additional notes on stomach contents of sperm whales Physeter macrocephalus stranded in the north-east AtlanticThe stomach contents of seven male sperm whales Physeter macrocephalus (Odontoceti:
Physeteridae) from the north-east Atlantic were examined. One animal was stranded on 27 November
1997 near Wassenaar (the Netherlands). Four became stranded the following day, 28 November
1997, on the island of Ameland (the Netherlands); three of these had food remains
in the ... ...

Residence and site fidelity of Sotalia guianensis in the Caravelas River Estuary, eastern BrazilBetween April 2002 and April 2005, 210 estuarine dolphin groups were sighted, with 58 animals individually identified. Fifteen dolphins were photo-identified just once, while only two animals were sighted in 15 different months. Some individuals showed long-term residence (more than 3 y). Residence rates showed heterogeneity in the dolphin's permanence of the estuary, with 60% of the indiv... ...

The habitat preferences of marine mammals west of Scotland (UK)This study used classification and regression trees (CART) to investigate and compare the habitat preferences of marine mammals in this area. Data were collected in early summer (June/July) in 2004 and 2005 and the distribution of marine mammal species was compared to 10 ecogeographic variables (EGVs). Of 13 species of marine mammals sighted during the study, there were sufficient sighting... ...

First insights into the biochemistry ofSabella spallanzanii(Annelida: Polychaeta) mucus: a potentially unexplored resource for applicative purposesAlthough mucus plays many different roles among marine invertebrates, relatively little is known about the link between biochemical structure and function. In the present study we focused on some physical and chemical properties of the polychaeteSabella spallanzanii 's mucus such as viscosity, osmolarity, electrical conductivity, elemental composition, the protein... ...

Seasonal changes in diatom biomass, sediment stability and biogenic stabilization in the Severn EstuaryEpipelic diatoms represented the dominant microphy tobenthos on the intertidal mudflats of the Severn Estuary, south-western Britain. Algal biomass (measured as chlorophylla concentration) varied over a seasonal cycle and was strongly correlated with sediment shear strength and critical shear stress and therefore with position on the shore. High levels of diatom b... ...

The Influence of water flow rate on Pumping Rate in Mytilus Edulis using a Refined Direct Measurement ApparatusINTRODUCTION Work on pumping and filtration rates of bivalve molluscs was initially concerned with the physiological concept of pumping water through the mantle cavity. Comprehensive reviews are given by Winter (1970) and Ali (1971). The methods are of two kinds; direct, in which the flow of exhaled water itself is measured, and indirect, in which the rate of clearance of f... ...
