Struktur und Dynamik der Spinnenpopulationen in Buchenw?ldern des Sollingt strata is given. For the older beech stand the horizontal distribution in the litter is demonstrated for total spiders and three abundant species..The phenology of . (O.P.-Cambridge), which, with up to 170 adult ind./m., is the most abundant species, is shown by means of a graph.

Zur Abundanz- und Biomassendynamik der Tiere in Buchenw?ldern des Solling Ind./m. and 10,6 kg dry weight/ha. The biomass determined with ground-photoeclector (Production an Imagines) per year is 14 kg dry weight/ha (4700 Ind./m. year). Hatching abundance and body size of the weevil . L. showed significant correlation with one another.

Intraspezifische Schwankungen der Kalorischen Werte Biologischer Materialiensons for this intraspecific variability of the caloric values are developmental, nutritional, seasonal and sexual differences of the stages involved. Also some climatic factors seem to play an important role for the energetics of some groups of organisms.

Simulationsmodelle von Wald?kosystemen: Wie Wird der Teilproze? Mineralstoffaufnahme Gesteuert?tion, annual uptake of several elements and concentrations in soil and litter layer solutions, are used in the calculation of MFK-values. Results range from 0.076 for Al to 120 for P. It is concluded that eventual simulation models of the mineral cycling system must include information on the state of the plant system.

Struktur und Dynamik von Staphyliniden-Populationen in Buchenw?ldern des Sollingrum of species can be exactly described with special regard to structure and dominance. Particular interest is given to phenology and dynamics of abundance of the most dominant species, whose biology and lifetables were unknown with only few exceptions.

Nahrungsspektrum und Nahrungskonnex von Pterostichus Oblongopunctatus (F.) und Pterostichus Metalliccarnivorous on a wide range of prey. Although no food preference could be proved there was a close correlation between biology and phenology of predator and prey respectively. The availability of a certain species of prey is further influenced by peculiarities like hardness of the elytra, which may change during the life cycle.
