    Density, biomass, and community structure of soil macroinvertebrates were studied in five types of plots developing by secondary succession at 2, 7, 20-30, 60-90 and >150 years after last major disturbance. Formicidae, Diplopoda, and larval Diptera constituted the highest density, while Coleoptera, Isoptera, and Oligochaeta were among the most important groups in terms of total biomass. The highest numbers of morphospecies were recorded in the oldest plots. The proportion of invertebrates found in deeper soil (9-16 cm) generally decreased with successional age. This may be attributed to more pronounced downward migration of soil macrofauna during drier periods of the year in earlier succession plots where the soil could be more sensitive to desiccation

    Abundance, biomasa a struktura společenstva byly sledovány na pěti plochách spontánní sukcese o stáří 2, 7, 20-30, 60-90 a více jak 150 let. Mravenci, larvy dvoukřídlých a mnohonožky se podílely nejvíce na celkové abundanci, zatímco brouci, termiti, a žížaly se podíleli nejvíce na biomase. Množství bezobratlých nalezených ve větší hloubce klesalo se sukcesním stářím
