A STUDY IN ANIMAL ECOLOGY 



Designed to serve as a reference work and 

 textbook in the New Science of Animal Ecology 



By VICTOR ERNEST SHELFORD 



Assistant Professor of Zoology in the 

 University of Illinois 



Illustrated with 300 figures, maps, and diagrams 



THIS volume by Professor Shelford pre- 

 sents the principles of field ecology, 

 illustrated by the more widely distrib- 

 uted animal habitats of the eastern half of 

 temperate North America, and the aquatic 

 habitats of a much larger territory. The 

 material has been accumulated during ten 

 years of field study, from the point of view of 

 modern ecology, in various parts of the United 

 States, though most of the material is drawn 

 from the Chicago Region. The book is de- 

 signed to serve as a reference work and a 

 textbook in the new science of field ecology.
