    Notes: [Auszug] In our technique the animals are placed in a small vessel of still water and observed or photographed against a black background. The milk is injected into the water above the animal from a row of fine jets (Fig. I, A) connected to a syringe. The syringe is operated manually by means of a screwed ...

    Notes: [Auszug] However, critical observations on Balanus balanoides and Chthamalus stellatus during recent years have shown a marked change in their distribution, indicating a general recession of Balanus from its southern and western limits, and a corresponding increase in Chthamalus. Conclusive evidence for ...

    Notes: [Auszug] DURING the last two years attempts have been made to review the work of Widmark1, Gemmill2, and Orton3 on the ciliation and mode of feeding in Aurelia aurita (Linné). The investigations have not been completed owing to the difficulty in obtaining ...

    Notes: [Auszug] It seems most improbable that any of these species could be excluded from Ireland on account of climatic or hydrographic factors. While all are relatively warm-water forms, they extend to parts of the British coast (St. George's Channel, and, in the case of Elminius, the North Sea) which are ...

    Notes: [Auszug] Littoral deposits may contain considerable amounts of coal : in the Isle of Man, at one beach near which colliers are unloaded, the coal content may approach 10 per cent at certain times and levels. Determinations on core samples taken at mid-tide level from this beach have shown the 'organic ...

    Notes: [Auszug] Changes in the chemistry and biology of the English Channel waters off Plymouth in the 1930s were a talking point for marine scientists 30 and 40 yr ago. The reversal of many of the changes, beginning in 1965 and continuing to 1979, may cause equal controversy about the stability of the ecosystem ...

    Notes: [Auszug] Our specimens of Pogonophora were obtained on May 4, 1957, by R.V. Sarsia, at a single station just west of the Little Sole submarine promontory: position, lat. 48 ° 28' N., long. 10 ° 04' W.; depth, 700 fathoms by echo-sounding, with a relatively level profile; bottom deposit, mud ...

    Notes: [Auszug] The late Prof. J. H. Orton was much interested in the phenomenon of sea foam, and wondered if considerable amounts of plankton and organic debris might not be brought ashore by this means (and by wave-action in general) to form a source of food for limpets and other intertidal animals. At his ...

    Notes: [Auszug] Observations on fine structure, metabolic enzymes and stable isotope ratios of several species of Pogonophora from a wide range of habitats suggest that members of this enigmatic phylum of worm-like deep-sea animals use internal chemoauto -trophic bacteria as part of their nutrition, allowing them ...
