The Journal of Ecology. An International Quarterly Review of Plant and 

 Animal Ecology and Geography, Soil Investigation, Planktonology, and Nature Pro- 

 tection. Edited for the British Ecological Society by Frank Cavers. 



The Journal of Ecology aims at presenting a record of and commentary upon 

 the progress of Ecology, considered in its widest sense, throughout the world. The 

 greater portion of the Journal 's devoted to single and grouped notices and reviews^ 

 including not only work dealing with general principles, methods, surveys, and other 

 ecological studies, but also publications in Geography, Geology, Meteorology, Clima- 

 tology, Physiology and Anatomy, the science of soils (soil physics, soil chemistry, and 

 tlie investigation of so'I flora and fauna), and other branches of Natural Science so 

 far as these have a direct bearing upon Ecology — the relationships of plants to their 

 environment in the widest sense, including the inter-relationships of plants and 

 animals. In brief, it aims at furnishing a comprehensive review of the entire field 

 of Ecology. 



The annual subscription price of The Journal of Ecology, including postage 

 to any part of the world, is $3.75; single copies Si. 25 each. The present volume is 

 volume I; a new volume will begin in March, 1914.
