PEANID ECOLOGY OF ORIO: 
A GENERAL OUTLINE. 
To contain a discussion of ecological principles illustrated by the 
aid of Ohio plants and an ecological treatment of the Ohio 
flora. With maps, charts and illustrations. 
JOHN H. SCHAFFNER AND FREDERICK J. TYLER. 
Inrropuctory Note. — Since a topographic survey of 
the state is now in progress and Dr. Kellerman’s catalogue 
of the higher plants of Ohio is nearly complete, the time 
was thought propitious to begin active work on the plant 
ecology. Although part of the work will be merely the 
compilation of facts already ascertained, nevertheless to 
accomplish the project now in mind will mean an enormous 
amount of investigation and exploration. It is therefore 
very desirable to get a union of forces, that the work may 
be pushed along all lines to a rapid completion. In order 
to accomplish this result we call upon all botanists in the 
state to assist in the work. The results will be published 
from time to time in the Ohio Naturalist, in the Annual 
Report of the Ohio State Academy of Science, or in any 
other suitable medium. We desire communication with 
any who wish to take up work along this line. After the 
ground has been covered in a general way by preliminary 
reports, there will be a substantial record from which an 
accurate ecology of the state may be written by those who 
may be interested in the subject at that time. With such 
a consummation in view we offer the following outline: 
I. INTRODUCTION. 
t. General survey of the irritable, responsive, and 
adaptative nature of plants. 
2. Definition and scope of ecology. 
3. Review of “Lehrbuch der oekologischen Pflanzen- 
geographie.” FE. Warming.
