Soil organisms, including earthworms, are a key component of terrestrial ecosystems. However, little is known about their diversity, distribution, and the threats affecting them. We compiled global dataset sampled earthworm communities from 6928 sites in 57 countries as basis for predicting patterns abundance, biomass. found that local species richness abundance typically peaked at higher latitudes, displaying opposite to those observed aboveground organisms. high dissimilarity across...
Increasing demand for biofuel has intensified land-use change (LUC) sugarcane (Saccharum officinarum) expansion in Brazil. Assessments of soil quality (SQ) response to this LUC are essential quantifying and monitoring sustainability production over time. Since there is not a universal methodology assessing SQ, we conducted field-study at three sites within the largest sugarcane-producing region Brazil develop SQ index (SQI). The most common scenario (i.e., native vegetation pasture...
Core Ideas The SMAF efficiently detected soil quality changes under Brazilian tropical conditions. Soil Quality Index was 0.87 (native vegetation), 0.70 (pasture), and 0.74 (sugarcane). Sugarcane expansion improves quality, mainly due to increasing chemical quality. SMAF–Soil significantly correlated with organic C stocks. is useful for monitoring in sugarcane production. Management Assessment Framework (SMAF) developed evaluate impacts of land use management practices on (SQ), but its...
Precipitation changes among years and locations along gradients of mean annual precipitation (MAP). The way those interact affect populations soil organisms from arid to moist environments remains unknown. Temporal spatial in could lead shifts functional composition communities that are involved key aspects ecosystem functioning such as primary production carbon cycling. We experimentally reduced increased growing-season for 2 y field plots at arid, semiarid, mesic grasslands investigate...
PROGRESS AND CHALLENGES.Microalgae biomass has been described by several authors as the raw material with greatest potential to meet goals of replacing petroleum diesel biodiesel while not competing arable land suitable for food production.Research groups in different countries are seeking most appropriate production model productivity, economic viability and environmental sustainability.This review focused on recent advances challenges
Abstract Global climate change is causing plants and other organisms to naturally expand their ranges higher latitudes or altitudes. This expansion leading a strong reshuffling of biotic interactions with consequent ecosystem functions in the new ranges. We report here that soil fauna communities respond strongly cushion large‐scale latitudinal gradient Qinghai–Tibet Plateau. Local taxonomic, functional, phylogenetic diversity nematodes increased presence independently gradient, but became...
Abstract The fraction of primary productivity allocated below‐ground accounts for a larger flow carbon than above‐ground in most grassland ecosystems. Here, we addressed the question how root herbivory affects allocation dominant shortgrass prairie grass response to water availability. We predicted that high levels by nematodes, as seen under extreme drought sub‐humid grasslands, would prevent biomass normally expected low exposed blue grama Bouteloua gracilis , which net steppe central and...
Free-living nematodes are one of the most diverse metazoan taxa in terrestrial ecosystems and critical to global soil carbon (C) cycling through their role organic matter decomposition. They highly dependent on water availability for movement, feeding, reproduction. Projected changes precipitation across temporal spatial scales will affect free-living contribution C with unforeseen consequences. We experimentally reduced increased growing season 2 years 120 field plots at arid, semiarid,...
Microbial communities can be structured by both deterministic and stochastic processes, but the relative importance of these processes remains unknown. The ambiguity partly arises from an inability to disentangle soil microbial confounding factors, such as aboveground plant or anthropogenic disturbance. In this study, we characterized contributions determinism stochasticity assembly bacterial across a large environmental gradient undisturbed Antarctic soils. We hypothesized that harsh soils...
Abstract Land use change ( LUC ) alters soil structure and, consequently, the functions and services provided by these soils. Conversion from extensive pasture to sugarcane is one of largest land transitions in Brazil as a result growth domestic global demands bioenergy. However, impacts expansion on under remains unclear, especially when considering changes at microscale. We investigated whether for cultivation impacted microstructure quality. Undisturbed samples were taken two layers (0–10...
