Sabellariaspinulosa reef: a scoring system for evaluating ‘reefiness’ in the context of the Habitats DirectiveJournal of the Marine Biological Association of the United Kingdom - Tập 86 Số 4 - Trang 665-677 - 2006
Vicki J. Hendrick, R.L. Foster-Smith
‘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. Guidelines are
proposed for... hiện toàn bộ
Sabellaria Colonies At Duckpool, North Cornwall, 1961–1970Journal of the Marine Biological Association of the United Kingdom - Tập 51 Số 3 - Trang 509-580 - 1971
Douglas Wilson
Between May 1961 and November 1970 almost monthly visits were made to Duckpool,
an exposed shore on the north coast of Cornwall, where Sabellaria alveolata (L.)
is the dominant organism on low-level rocks uncovered only by spring tides.
Massive colonies several feet across and up to some 2 ft thick, formed mainly of
shell particles cemented together by the worms, as well as many smaller colonies

Sabellaria Alveolata (L.) At Duckpool, North Cornwall, 1975Journal of the Marine Biological Association of the United Kingdom - Tập 56 Số 2 - Trang 305-310 - 1976
Douglas Wilson
INTRODUCTIONBetween 4 May 1973 and 29 March 1975 we did not visit Duckpool.
Indeed after the 1973 visit (Wilson, 1974, pp. 429–30) the intention had been to
discontinue observations on colony formation and growth, for it seemed unlikely
that much more data of value were obtainable, and that is still true. However,
at Easter 1975 Monsieur Yves Gruet, who has done much excellent work on
Sabellaria a... hiện toàn bộ
Effects on Dietary Lipids of the Marine Bivalve Scrobicularia Plana Feeding in Different ModesJournal of the Marine Biological Association of the United Kingdom - Tập 71 Số 3 - Trang 635-653 - 1991
Stuart A. Bradshaw, Susumu Ohara, E. D. S. Corner, G. Eglinton
Changes in dietary lipids were investigated in laboratory feeding experiments
simulating herbivorous and coprophagous modes of feeding in the bivalve mollusc
Scrobicularia plana (da Costa). The dinoflagellate Scrippsiella trochoidea
(Stein) was used as the food in herbivory experiments while faeces from the
crustaceanNeomysis integer (Leach) feeding on Scrippsiella were used as the food
in coproph... hiện toàn bộ
Dietary lipid changes during herbivory and coprophagy by the marine invertebrate Nereis diversicolorJournal of the Marine Biological Association of the United Kingdom - Tập 70 Số 4 - Trang 771-787 - 1990

Changes 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 Neomysis integer (Leach) after feeding on this same alga, were
used as the... hiện toàn bộ
Changes in lipids during simulated herbivorous feeding by the marine crustaceanNeomysis integerJournal of the Marine Biological Association of the United Kingdom - Tập 70 Số 1 - Trang 225-243 - 1990
Stuart A. Bradshaw, Susumu Ohara, Eric D. S Cornert, G. Eglinton
A laboratory study simulating herbivorous feeding was carried out with the
marine crustaceanNeomysis integer(Leach) and the dinoflagellateScrippsiella
trochoidea(Stein). Analyses of the total fatty acids, sterols and fatty alcohols
in the food and faecal material, and in the animal tissue, have allowed the
detailed changes in the dietary lipids during feeding to be characterised.The

A preliminary investigation of the variation of vitamin B12in oceanic and coastal watersJournal of the Marine Biological Association of the United Kingdom - Tập 35 Số 3 - Trang 609-620 - 1956
C. B. Cowey
The presence in the sea of vitamin B12, or of its analogues, has been found
necessary for the growth of several species of unicellular plants (e.g.
Provasoli & Pintner, 1953; Droop, 1954, 1955).Bioassays of the quantities in
inshore waters during winter have been made by Lewin (1954) and by Droop (1954).
The present investigation, carried out in 1955, was designed to extend this
study and compare ... hiện toàn bộ
On the Nutrition and Metabolism of Zooplankton VII. Seasonal Survey of Nitrogen and Phosphorus Excretion by Calanus in the Clyde Sea-AreaJournal of the Marine Biological Association of the United Kingdom - Tập 50 Số 2 - Trang 525-560 - 1970
E. I. Butler, E. D. S. Corner, S. M. Marshall
In a recent study (Butler, Corner & Marshall, 1969) it was found that the
excretion of nitrogen and phosphorus in soluble form by Calanus finmarchicus
caught at Garroch Head in the Clyde sea-area was significantly higher in spring
when plant food was plentiful, than in autumn when plant food was in relatively
short supply. The present survey has extended this earlier study to include more

Photochemical combustion of organic matter in sea water, for nitrogen, phosphorus and carbon determinationJournal of the Marine Biological Association of the United Kingdom - Tập 48 Số 1 - Trang 143-152 - 1968
Fräser A. Armstrong, Susan Tibbitts
A photochemical reactor, using a medium power mercury arc lamp for oxidation of
organic matter in sea water, is described. The decomposition of some known
compounds in distilled water and in sea water, using a 380 W lamp, was followed.
First order kinetics with rate constants in the range 0·2–4·0 h−1 were observed.
All the nitrogen compounds tested, including urea and some of its derivatives,
were... hiện toàn bộ
Shallow-Water Zonation of Sea-Loch Benthos and Its Relation to Hydrographic and Other Physical FeaturesJournal of the Marine Biological Association of the United Kingdom - Tập 54 Số 1 - Trang 223-249 - 1974
J. D. Gage
Surveys 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 diving
