6 THE ECOLOGY OF ANIMALS 



is published in unexpected places. Most of the 

 British work is noticed and abstracted briefly m 

 the Journal of Animal Ecology. On the economic 

 side, attention should be drawn to the abstracts con- 

 tained in the Review of A'pjMed Entomology, which 

 covers in its two series Agricultural Entomology 

 on the one hand and Medical and Veterinary 

 Entomology on the other hand. Overlapping some- 

 what with the latter is the Tropical Diseases Bulletin, 

 which contains also very comprehensive abstracts. 



General books on animal ecology are still few in 

 numbers. The following may be mentioned : Shel- 

 ford (1913 and 1929), Chapman (1931), and Elton 

 (1927). Shelford's later book mainly concerns the 

 methods of analysing the physical environment and 

 the ways in which it affects animals. Chapman 

 covers the theories of animal ecology, methods, and 

 literature. The book by Elton treats animal inter- 

 relations and numbers more fully than the others, 

 while containing less on the physical side, and upon 

 insects. Among the more useful recent are Allee et 

 al. (1949) and Odum (1953). For a stimulating and 

 extensive polemic about populations, Andre wartha 

 and Birch (1954) is good reading.
