Titre : British prosobranch molluscs : their functional anatomy and ecology Type de document : texte imprimé Auteurs : Fretter, Vera, Auteur Editeur : Ray society Année de publication : 1962 Importance : 755 p. Format : 26 cm. Langues : Anglais (eng) Index. décimale : 594 Mollusques Résumé : In the nineteenth century there appeared three accounts of British Molluscs which have been the standard works of reference for students of these animals ever since. They were Alder & Hancock's British Nudibranchiate Mollusca (1845-55), Forbes& Hanley's History of the British Mollusca, and their Shells (1848-53) and Jeffreys' British Conchology (1863-69).
Great as is the debt which all malacologists and conchologists owe to these authors, the fact remains that their severely systematic approach to their subject, their attitude to zoology and even their vocabulary and style are very different from their modern counterparts. The molluscs have, indeed, been shown to be excellent material for work on functional morphology and for demonstrating the adaptation of structure to function and of both to the ecological niche which the animals occupy, though they have proved less suitable for, and less productive of results in certain fields of physiology. The rich findings of this modern malacology have not as yet received any synthetic treatment, though Morton has made a brave attempt to indicate their main lines in his little book The Mollusca (1959).
The whole molluscan field, however, is really too great to deal with except in such a brief way and we have, therefore, in preparing this attempt to present the results of all this work, limited ourselves to the pros branch gastropods, the group with which we are most familiar, and which, to our thinking, shows the interrelationships of structure and function and habitat in more varied and convincing ways than any other.
We have not set out to write a systematic account nor one which will permit the identification of specimens collected in the field, believing that this was a ground already adequately covered by others and one, to tell the truth, in which we were less interested than in that of functional morphology, where, too, the need for synthesis is greater. We have, however, included a list of British prosobranchs with some indication of their precise habitat and present distribution and a reference which will permit those who are interested to refer to Forbes & Hanley's or Jeffrey's works for fuller descriptions of shell and external features.
These two works will, indeed, long live on for such use because of the excellence of their descriptive text and figures. We have written our account primarily on the basis of work done on those prosobranchs which live in Britain and the British seas, but when it has seemed necessary or desirable to refer to animals which are not found in these localities in order to increase the value of a discussion, we have not hesitated to do so. Whilst the text rests largely on published work much of what is included without reference to an author is new material from our unpublished investigations. Although the writing of the book was naturally started by each author undertaking the sections which his interests and experience rendered most apt, each of us has read and reread the other's writing, and the result is (and is intended to be) a genuinely joint effort; both of us are therefore equally responsible for the shortcomings, whether of fact, style or treatment, which the discriminating reader will inevitably discover.British prosobranch molluscs : their functional anatomy and ecology [texte imprimé] / Fretter, Vera, Auteur . - Ray society, 1962 . - 755 p. ; 26 cm.

Titre : Pulmonates : functional anatomy and physioloy (volume 1) Type de document : texte imprimé Auteurs : Fretter, Vera, Auteur Editeur : Academic press Année de publication : 1975 Importance : 417 p. Format : 23 cm ISBN/ISSN/EAN : 978-0-12-267501-0 Langues : Anglais (eng) Index. décimale : 594 Mollusques Résumé : Gastropod molluscs have shown a remarkable ability for adapting to varying ecological niches; from an undoubted marine origin they have spread to occupy most types of aquatic and terrestrial habitat, an evolution made possible by the extreme plasticity of their bodies. About half the species are pulmonate and although they constitute less than a third of gastropod species in the British Isles, they dominate the molluscan fauna in more extensive land masses. Everywhere they are of economic importance being serious horticultural and agricultural pests as well as hosts for a number of parasites affecting man and his domestic animals.
Since these molluscs are easy to keep in captivity and show considerable resistance to operative techniques, they have proved convenient animals for a variety of physiological and pharmacological researches.
Volume 1 of Pulmonates is based on such studies, bringing together information from various sources relating to the functioning of the systems of the body and its embryology.Pulmonates : functional anatomy and physioloy (volume 1) [texte imprimé] / Fretter, Vera, Auteur . - Academic press, 1975 . - 417 p. ; 23 cm.

Titre : Studies in the structure physiology and ecology of molluscs Type de document : texte imprimé Auteurs : Fretter, Vera, Auteur Editeur : Academic press Année de publication : 1968 Importance : XVII-377 p. Format : 24 cm. Langues : Anglais (eng) Index. décimale : 594 Mollusques Résumé : Man has been attracted to molluscs since earliest times. They lived around his home and provided easily accessible food. Their shells were heaped on his kitchen midden to await the curiosity of the archaeologist and paleontologist who used these remains to reconstruct facts about predator and prey.
The shell, secreted and molded by the soft parts to their particular requirements, leaves in the fossil record a manifestation of the success of molluscan organization. This organization has proved its adaptability in a vast number of ecological niches, giving us over 80,000 different species, with some in more obscure habitats which have remained unknown until very recent years.
Recently discovered species have revolutionized our ideas of molluscan evolution: the hope of finding others is a challenge to the naturalist. Variety in structure is a hall mark of the phylum, and provides the anatomist with virtually inexhaustible material. Abundance in numbers, easy availability and endurance of laboratory conditions are attractions to the physiologist who regularly employs land, freshwater and marine snails as objects for the most advanced scientific techniques.
This ubiquitous appeal of molluscs to the scientist is illustrated in the list of chairmen and speakers who took part in this symposium jointly organized by the Zoological and Malacological Societies of London. It brought together people of widely divergent interests in the phylum, although only gastropods and to a lesser extent lamellibranches were under consideration. The occasion permitted us to discuss malacology with scientists from other countries and we are grateful to those who came from Europe, the United States and elsewhere to participate so freely in formal and informal talks.
Some will read the papers included in this volume to learn of advances in fine structure and physiology, others to appreciate the functional anatomy and ecology of unfamiliar species, or to concentrate on facts which can be deduced from the molluscan shell, living, fossilized or artificial. Whatever topic is selected the reader will see that the mollusc maintains its position as a challenge to human interest. We look forward to another occasion when we may survey the results of this challenge.Studies in the structure physiology and ecology of molluscs [texte imprimé] / Fretter, Vera, Auteur . - Academic press, 1968 . - XVII-377 p. ; 24 cm.
