摘要: Soil fauna is essential for ecosystem dynamics as it involved in biogeochemical processes, promotes nutrient availability, and affects the animal communities associated with plants. In this study, we examine possible relationship between soil microarthropod community on foliage production quality of shrub Pittocaulon praecox. We also arthropods to its foliage, particularly size main herbivores their natural enemies, at two sites contrasting vegetation cover productivity. The diversity microarthropods was assessed from samples collected monthly under P. praecox individuals over 13 mo. Specimens were identified species or morphospecies. Shrub productivity evaluated through amount litter produced. Resource by mean content (percentage weight) N, C, S, P 30 leaves each shrub. enemies determined measuring 20 adult specimens most abundant species. found a higher richness foliar open site, although lower closed site. Shrubs growing site tend produce more, larger, nutritionally poorer (lower nitrogen content) than Herbivores larger significant positive leaves. general, both fauna, well organisms belonging trophic levels, affected primary These findings highlight need simultaneously consider least four levels (soil organisms, plants, herbivores, enemies) better understand functioning these systems responses environmental changes.
