Abstract The aim of this study was to evaluate the litter dynamics in the seasons of the year in three areas: Forest formation Cerradão (CE), and in two hybrids stands of Eucalyptus urophylla × E. grandis with different ages: E1 (34-58 months) and E2 (58-82 months). The produced litter, stored litter and the remaining mass was collected over 720 days. The evaluation of the remaining litter mass in each area was performed from the random distribution of 648 litter bags on the soil. Chemical analyzes (N, P, C) and the structural components of the cell wall (lignin, cellulose and hemicellulose) of the remaining litter were performed. The C of the litter stock was also determined. For both years of evaluation were observed higher biomass and C content in litter at E2. In contrast, the highest decomposition rate was for the CE, especially in the second year of evaluation (mass remaining at 720 days of 35%, 37% and 23% for E1, E2 and CE, respectively), attributed to the higher apparent liberation of N, soil moisture and biodiversity in the native area. Lignin contents increased, cellulose decreased, and hemicellulose remained stable throughout the 720 days. It was also observed an increase in the N and P concentration of the remaining mass and positive correlations among the remaining mass and the C:N and C:P ratios. The C:N ratio of litter was ≥ 76:1 at time 0 and ≥ 30:1 at 720 days for the three areas. |

Soil fauna performs several functions in native and anthropized ecosystems, being affected by spatiotemporal variation and by environmental resource availability. However, there is still a gap in knowledge of how land use change, climatic seasonality, and soil and climate variables impact trophic groups of soil fauna in semiarid environments. We investigated the abundance of detritivores, herbivores, microbivores and predators in three land uses (native forest, pasture and irrigated agriculture), during the dry and wet season, using two collection methods (manually separated soil monoliths and pitfalls) and the effects of soil and climate variables on soil fauna. Detritivore and predator activity was predominant in the 0− 20 cm layer (monoliths), while herbivores and microbivores abundance were greater on the soil surface (pitfalls). Irrigated agricultural areas had higher abundance of soil fauna and a different community structure from native forest and pasture, due to continuous water availability. Climatic seasonal variables (temperature, air humidity, solar radiation and wind speed), soil characteristics (Macronutrients, C, C:N ratio, pH and CEC) and land use change impacted all trophic groups. Irrigated agriculture in semiarid regions can serve as a refuge for soil fauna, bringing light to a new community structure that can be shaped to shelter the highest possible biodiversity. |
