THE ECOLOGICAL SURVEY OF ANIMAL COMMUNITIES: WITH A PRACTICAL SYSTEM OF CLASSIFYING HABITATS BY STRUCTURAL CHARACTERS.

The article examines the ecological survey of animal ecology, using a practical system of classifying habitats by structural characters. The paper aims to clarify the position of community surveys in animal communities, by contrasting as plainly as possible their theoretical aims with the practical limitations that obstruct their achievement. It also presents a simplified system of assembling and classifying information about habitats at both a species and a community level, which seeks to distinguish the limitations of the material without deterring the value of the integrated results.
