    Notes: [Auszug] In the north-east Atlantic area, F. inflatus is recorded from Iceland, Norway, Sweden, the Faeroes and the Shetlands ; it is not recorded, however, from the Orkneys. Lund2 has reported a recent immigration of a larger form of the species (F. inflatus L. f. edentatus (De la Pyl.) Rosenv.) into ...

    Notes: [Auszug] SIR,-I am much in sympathy with Kenneth Mellanby (October 2) and especially his final paragraph on inexpensive biological research. Having simple research needs-eyes, a waterproof and time for fieldwork and contemplation-I have been conscious throughout my career as a littoral ecologist, of the ...

    Notes: Abstract Although logical compromise agreement between all the conflicting users of the sea seems the most obvious way to protect marine life, we have in practice mainly ad-hoc restrictions aimed at protecting habitats or species, or at trying to prevent chemical/physical deterioration of the environment. The establishment of reserves on biological rather than touristic grounds necessitates consideration of the criteria, appropriate to marine life, that should be used. Successful reserve management or species protection measures depend upon distinguishing between natural and man-made changes, an ability that can be enhanced in part by appropriate disturbance experiments. Anti-pollution measures have centred upon effluent input rather than biological effect in the field, with “acceptable discharge levels” being based upon lethal and sub-lethal experimental effects. But the ultimate criteria of environmental well-being are ecological responses at the population and community levels where, unfortunately, many natural and man-made influences produce similar changes. Knowledge of community dynamics and a resulting ability to discount natural events require long-term studies and are slow to accumulate. Thus while short-term sublethal studies proliferate many ecological data remain uninterpretable except in localities of gross and obvious pollution (including tanker accidents). The scarcity of sub-lethal and ecological effects in the field is even supplemented by ecological changes that are contrary to expectations based on pollution loadings. Is this because ecological expertise is still inadequate, or because experimental and environmental loading data grossly overstate the risks and are largely irrelevant at the community level? Can we assume that fears of chronic pollution are unfounded or must we intensify our efforts? If the latter, in which direction?

    Notes: [Auszug] SIR,-I wish to associate myself with the views of R. S. Glover (Nature, 225, 570; February 7, 1970) and in particular his comments on the relationship between field data, the analysis of natural fluctuations and the study of marine pollution. To the number of points which, as he says, are ...

    Notes: Abstract The effect of geographical differences in breeding cycles on the recruitment variation of the limpets — Patella vulgata L., P. aspera Röding and (to a limited extent) P. depressa Pennant — has been studied over much of their range in Britain and NW. Europe. In spite of considerable annual and local variation in recruitment success, broader patterns can be distinguished, which can be linked to spawning times and factors affecting the survival of newly-settled spat. The breeding cycles of P. vulgata and P. aspera differ across their ranges in that, in both species, spawning begins, and gametogenesis ends, earlier in the north and east than in the south and west. The cause of these differences can be correlated with geographical and annual differences in sea temperature over the potential breeding periods, and can be related to the regional incidence of conditions found experimentally to be necessary for successful settlement and survival of spat during a critical stage of their growth. The significance of this ‘temperature window’ in determining the littoral and geographical distribution of the species is discussed.

    Notes: Abstract Size/frequency samples have been taken from populations of the trochid gastropod Gibbula umbilicalis at a number of sites around the British Isles each year since 1978. In the North of Scotland, close to the limit of the species distribution, recruitment was generally poor and populations were sparse and dominated by large old individuals. While such poor recruitment may reflect the low density of adults and the shortage of nursery areas, a distinct temporal pattern of recruitment was also evident. At the start of our study, the majority of sites had population structures biased towards young animals implying that conditions for the settlement of larvae or their subsequent survival had been favourable over a wide area. In the years that followed only the enclosed Loch Eriboll regularly received substantial recruitment. Further to the south, in Wales and S.W. England, recruitment was usually more regular, populations were more dense and individuals smaller.
