| For the ecologist systematic units are actors in a play. Whatever their christian- and family-names may be — it is their role, whether master or servant, whether villain or hero — which determines the character of the performance. This performance has, moreover, the property of being both continuous and simultaneous: all scenes are given at once. Such a continuous and simultaneous performance is called a biocoenosis. In a great many ways, a biocoenosis reminds us of an organism. For the coördination between organs or tissues, or even cells is also continuous and simultaneous. A biocoenosis is a higher vital unit, and may be approached by the same methods which we use for the study of organisms (V. D. KLAAUW (24)). In the systematic approach we establish... |

| Any community of plants is characterized in four main ways — by a definite floristic composition, by definite life-forms, by a definite structure and by a definite habitat or environment. Of these four characters, floristic composition is the most important in defining a plant community in any particular locality. It is a commonplace fact that many parts of the world may show communities of higher plants identical in life-form, structure and habitat but differing widely in their floristic composition. By utilising the three last named characters of a plant community we can group our unit biocoenoses into larger groups. |

| In the development of the various scientific disciplines certain contacts have been established between neighbouring sciences, while other endeavour still proceeds almost on its own. The study of the influence of the environment on chemical reactions has given us a large part of physical chemistry, while the inverse, the study of the influence of chemical reactions on the (natural) environment has been, in the last decades, developed as geochemistry. Much of our physiology and ecology deals with the influence of the environment upon the organism, while the inverse, the influence of the organism upon the natural environment (geobiology) has hardly been studied systematically. This influence is great, as already realized by Pasteur a century ago. Moreover,... |
