to engage the attention of the potential mate and as the inevitable 

 conflict is dramatized by tiny grouse chicks feeding on grubs but 

 menaced by a snake which is in turn captured by an alert hawk. 

 The ecologist will find much of interest in the implicit story of 

 animals and plants in their environment; plant succession and the 

 growth of a seedling to climax forest. But there is more to the film 

 than this, because it has an overall philosophy which should be of 

 particular interest today, in that it serves as an introduction to an 

 area relatively untouched by man and successfully maintaining a 

 natural balance of its own. As such it demands the special attention 

 of the student, the expert, the philosopher and the average citizen 

 who believes in a kind of religion of nature. For a film with modest 

 goals this carries amazing weight.

PLANT AND ANIMAL COMMUNITIES: 

 THE PHYSICAL ENVIRONMENT 



Color Sound Coronet Films 



11 minutes Rental Sale 



The various physical conditions (altitude and atmospheric con- 

 ditions, heat and light, water, soil ) of several different environments 

 are described in this film together with the effects these conditions 

 have on plant and animal communities of the area. A deciduous 

 forest, a mountain coniferous forest, grassland, and desert are the 

 environments studied. 



As an introduction to the concept of a biome this is a very useful 

 film. The narration and photography are unusually competent, 

 and the careful use of labels over the photographs emphasizes the 

 ideas presented.
