BRITISH 
ECOLOGY 
SOCIETY 
EDITED FOR THE 
BY 
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 quarterly issue contains original articles and 
notes on ecological topics of current importance, including methods of ecological study and 
research ; reviews aqd notices of publications of general ecological bearing of work upon 
plant and animal communities in all parts of the world ; and reports and notices 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 will take 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, Plankton ology, 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. 
THE JOURNAL OF ECOLOGY is published twice a year— in May and November. 
The annual subscription price, including postage to any part of the world, for a single copy 
of each of the four issues making up the annual volume, is Fifteen Shillings (155.) net;
