THE 
JOURNAL OF ECOLOGY 
EDITED FOR THE 
BRITISH ECOLOGICAL SOCIETY 
By A. G. TANSLEY 
The objects of THE JOURNAL OF ECOLOGY, which was founded in 1913, are (1) to 
foster and promote the study of Vegetation and Ecology, especially in the British Isles, 
(2) to afford an outlet for original work on these subjects, and (3) as far as possible to 
present a record of and commentary upon the progress of these studies throughout the 
world. Each issue contains original articles on Vegetation and Ecology, reviews and 
notices of current literature relating to these subjects throughout the world, and reports 
and notices of the meetings and work of the British Ecological Society. 
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 
(Geologyq 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 two or three issues of not less than 64 pp. are published during the year. 
It is hoped that in the future it may 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. 
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 (25s.), which includes the supply of one copy of each issue of the Journal , to 
the Secretary, Dr. E. J. Salisbury, The Briars, Crosspath, Radlett, Herts.
