Sažetak
Soil animals play key role in functional processes in soil ecosystem such as carbon sequestration or transformation of organic matter. Thus, census of the global biomass of soil animals is key for understanding the structure and dynamics of soil ecosystem. However, quantitative view of how the different functional groups of soil fauna are distributed globally across biomes is underestimated. We present meta-analysis of total 68, both, either experimental studies and/or reviews in which authors investigated density of soil animals across various biomes. We assembled the overall biomass composition of the various groups of soil animals across various biomes. Highest biomass of soil animals was recorded as follows: temperate grassland, taiga, tropical forest, temperate forest, tropical grassland, tundra, mediterranean vegetation and desert. In total, eleven functional guilds (Bacterial feeders, Earthworms, Fungal feeders, Herbivores, Litter feeders: macrofauna, Litter feeders: mesofauna, Omnivores ants, Omnivores others, Predators, Scavengers, Termites) were identified based on taxonomy and food strategy. Scavengers, termites, eartworms and predators showed highest biomass. Termites were dominant groups in tropical grasslands and surprisingly in deserts and mediterranean vegetation. Scavengers were dominant in temperate grasslands wile earthworms surprisingly dominated in temperate forest. Predators dominated in taiga forest. In conclusion, our study showed that biomass of soil animals is dominated in biomes with lower aboveground biomass (temperate grassland) while biomes with higher aboveground productivity (tropical ecosystem) showed lower biomass of soil fauna. Tropical ecosystem showed most of the animals related to aboveground biomass (leaf herbivores). Relative biomass of functional guilds of soil fauna varied across biomes. This finding could be explained due various climatic conditions and via changes effect of plant chemistry on spoil physical and chemical properties. Finally, we believe that the results described in this study will contribute to highlighting of functional role of global diversity of soil animals.
