Abstract
The authors investigated ,the Arthropods in the litter of an oak forest from bio-sociological and production-biological standpoints. On the basis of the Arthropods surveyed in an area of 100 50X50 cm squares the following results were obtained: 1. The 9836 specimens of Arthropods found in the 100 squares belong to altogether about 120 species. The average number of specimens occurring in 1 m2 was 393. Most of the Arthropods living in the area (8001 specimens, 81% of the total number) belong to 10 species, the other 110 species being represented by only the, remaining 1835 specimens, 18%. Hence in the structure of the cenosis only 9% of .the species living there play an important role: the other 91% are of subordinate significance. 2. The total weight of the above 10 species corresponds to a production of 13.5 kg calculated in average value per 1 ha area. 3. The two important life-forms of the species of the cenosis are: a) the “ants-isoecium”, represented by 3 species of ants, comprising 31.6% of the Arthropod individuals. b) the “Lithobius-isoecium“, represented by 1 species of Lithobius and 1 of Monotarsobius, comprising 12% of the Arthropods. These two isoecia are characteristic for the Arthropod cenosis of the area surveyed. In respect to P value the “Diplopoda-Isopoda isoecium” also plays an important role, its P value amounting to more than half that of all the 10 species mentioned. 4. In the litter of, an oak forest an area of about 1 m² is sufficient for distinguishing the species with high C and D values from the accidental species. The same,sized square is not enough to give a the average number of individuals in 1 m².
