THE 
JOURNAL OF ECOLOGY 
EDITED FOR THE 
BRITISH ECOLOGICAL SOCIETY 
Bv A. G. TANSLEY 
The objects of THE JOURNAL OF ECOLOGY are (i) to foster and promote in all 
ways the study of Ecology in the British Isles, serving as the organ of the BRITISH 
ECOLOGICAL SOCIETY ; (2) to present a record of and commentary upon the progress 
of Ecology throughout the world. Each issue contains original articles and notes on 
ecological topics of current importance, including methods of ecological study and re- Jj 
search ; reviews and notices of publications of general ecological bearing of work upon 
plant and animal communities in all parts of the world ; and reports and notic ;s of meetings 
of the British Ecological Society ; progress of the Nature Protection movement and of 
ecological work in Nature Reserves ; list of current literature. 
THE JOURNAL OF ECOLOGY , being largely a Review, is indispensable to those 
desiring to keep abreast of the extensive and widely scattered literature of Ecology, of which 
it takes a comprehensive view, including in its scope not only work dealing with general 
principles, methods, surveys, and other ecological studies, but also publications dealing 
with Plant and Animal Geography, Planktonology, the science of soils (soil physics, 
chemistry, and the investigation of soil floras and faunas), and other branches of science 
(Geology, Climatology, Agriculture, Forestry, &c.), so far as these have a direct bearing 
upon Ecology— the relationships of plants and animals to their environment in the widest 
sense, including the inter-relationships between plants and animals. In brief, it aims at 
furnishing a comprehensive review of progress in the entire field of Ecology, touching, 
as this field does, kindred branches of science on various sides. 
At present issues of not less than 64 pp. each appear in March and June, and a third 
larger issue in the autumn (200-240 pp. in all). With a larger circulation it would be 
possible to publish four quarterly numbers of 64 or more pages each. The Journal is 
illustrated by photographic plates of vegetation and by numerous figures in the text. The \ 
subscription price is one pound per annum. The quarterly issues are priced at seven 
shillings and sixpence each. Subscriptions for the Journal are payable in advance and 
should be sent to Mr. C. F. Clay, Cambridge University Press, Fetter Lane, London, 
E.C. 4, either direct or through any bookseller. 
Members of the British Ecological Society should send their annual subscription to the 
Society (25 s.), which includes the supply of one copy of each issue of the Journal, to 
the Secretary, Dr. E. J. Salisbury, The J 3 riars, Crosspath, Radlett, Herts.
