NATIONAL OCEANOGRAPHIC PROGRAM—1965 381 
#19, Biological extraction and accumulation in streams, 
a. Dr. C. J. Veiz, Chairman, Department of Environmental 
Health, University of Michigan and others. 
b. To determine the basic environment condition giving rise 
to formations of growths in streams. 
ec. To determine biological actions governing the rates of 
extraction of oxygen and to investigate the means of controlling or eliminating 
such formations. 
d. Various streams which react differently with respect to 
gross formation of biological growths, concentration of oxygen will be studied 
over periods of time and geographically, Basic investigations will be conducted 
in laboratories and in the natural streams. 
B, The National Science Foundation. 
The National Science Foundation sponsors a number of projects in 
the Great Lakes area. Sponsorship is primarily centered in the Division of 
Biological and Medical Sciences and the Division of Mathematical, Physical 
and Engineering Sciences. 
1. Relation of population density to growth and competition. 
a. Dr. Frederick E, Smith, Associate Professor of Zoology, 
University of Michigan. 
b. To describe the growth relations of certain populations 
in the Great Lakes. 
c. Numerous species in the family daphnidae are being. studied 
to relate the population growth to the population density and food density, 
Life table techniques are being used with mass cultures. All possible two- 
species systems are being followed to determine competitive relationships. 
*2, Functional analysis of certain plant communities. 
a, Mr. Pier Dansereau, Assistant Director, New York Botanical 
Garden. 
be To test and improve methods for analysis of various types 
of plants and to apply a large body of data for functional pe of 
phytosociological units in the Gaspe” Peninsula. 
c. The principal communities are being sampled Bek cane 
ecosystems under study include the mesophytic forest, riparian forest, open 
shrubby grass land, salt marshes, rocky cliffs, and barren fields.
