will decisively help in the solution of entomological problems, important also from the point of view of national economy. It had realized that the immense and by now almost baffling amount of facts and data will fall in place, - to become, when viewed coenologically , a coherent and living science.lt has also recognized that it is only this new view which can ever hope to appreciate adequately the effects of the present gigantic political, social,and economic transformations on nature and on our Globe.This triple recognition appoints coenology,both in Hungary and beyond her frontiers, as one of the leading sciences of biology. Over and above its shaping aspects on coenological researches, the new trend had its effects - concretely, factually, and, as an economist would say, summarily - on several scientific fields. I ask permittance to mention but four of them: 1. production-biology, 2. plant protection, 3. hydrobiology , 4. soil biology. 1. Production biology is a quite new science,born before our very eyes. Its task is to find and formulate the laws of the turnover of material and energy enacted in nature,and to study these processes. Production biology starts from the point that any given homogeneous area of the Globe,let it be a forest, a field, or an agricultural site, is able, between certain limits, to produce an identical amount of organic matter and the storing of an equivalent potential energy. We see,however, the play of oppositely operative forces in this so-called biological production, to wit, simultaneously with production there, are also processes hindering production,and a certain amount of consumption too. Agricultural production is thu3 nothing else but the utilization at the optimal grade of effectivity of biological production for the sake of man. It follows that the possibilities of agricultural production will, when all is said and done,be determined by productionbiological possibilities.
