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...
An experiment in >1000 river and riparian sites found spatial patterns controls of carbon processing at the global scale.
This review covers the heterogeneity in functions within fine root architecture order to clarify multiple of roots. Many characteristics, such as anatomy, physiology, morphology, and their consequences for ecosystem, differ among ages ontogenetic branching hierarchies. Individual age can be characterized by tissue development, with main tissues developing from primary secondary tissues. The physiological characteristics individual roots, absorptivity respiration rates, decrease increasing...
Abstract Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial functions and services. Little is known about their diversity distribution at large spatial scales, despite the availability considerable amounts local-scale data. Earthworm data, obtained from primary literature or provided directly by authors, were collated with information on site locations, including coordinates, habitat cover, properties. Datasets required, minimum, to include...
Rivers and streams contribute to global carbon cycling by decomposing immense quantities of terrestrial plant matter. However, decomposition rates are highly variable large-scale patterns drivers this process remain poorly understood. Using a cellulose-based assay reflect the primary constituent detritus, we generated predictive model (81% variance explained) for cellulose across 514 globally distributed streams. A large number variables were important predicting decomposition, highlighting...
Increases in the number of wild herbivores resulted understory degradation because their overgrazing forest ecosystems. Deer has occurred soil erosion Japanese beech forests where dwarf bamboo used to be densely covered. Soil can result a decrease carbon and nutrient contents, causing microbial respiration such ecosystems degraded. The objective this study was clarify effects erosion, which sporadically occurs within forests, on properties activity. indices, as maximum height exposed roots...
Springtails (Collembola) inhabit soils from the Arctic to Antarctic and comprise an estimated ~32% of all terrestrial arthropods on Earth. Here, we present a global, spatially-explicit database springtail communities that includes 249,912 occurrences 44,999 samples 2,990 sites. These data are mainly raw sample-level records at species level collected predominantly private archives authors were quality-controlled taxonomically-standardised. Despite covering continents, most come European...
• To understand the physiology of fine-root functions in relation to soil organic sources, heterogeneity individual root within a system requires investigation. Here heterogeneous dynamics systems are reported. The fine roots Chamaecyparis obtusa were sampled using sequential ingrowth core method over 2 yr. After color categorization, classified into protoxylem groups from anatomical observations. lengths with diarch and triarch fluctuated seasonally, whereas tetrarch length increased....
Abstract Aims Climate change can substantially alter ecological communities. However, we hypothesized that, even if novel communities emerge, those may not be in terms of functional composition. To infer the processes associated with rising temperatures, evaluated elevational taxonomic/functional turnover plant and invertebrate Because climate interacts synergistically other environmental factors, therefore is sole driver communities, also considered how composition would affected by...
Biomass allocation to fine roots often increases under soil nutrient deficiency, but the root biomass does not increase in old stands, even limitation. Therefore, morphology, anatomy, branching architecture and mycorrhization of may compensate efficiently for acquisition by low biomass. In this study, changes anatomy arbuscular mycorrhizal infection at each position clusters were evaluated relation stand age. A chronosequence (6–90 years age) stands a Cryptomeria japonica D. Don plantation...
Abstract Microbes play a critical role in plant litter decomposition and influence the fate of carbon rivers riparian zones. When decomposing low‐nutrient litter, microbes acquire nitrogen (N) phosphorus (P) from environment (i.e., nutrient immobilization), this process is potentially sensitive to loading changing climate. Nonetheless, environmental controls on immobilization are poorly understood because rates also influenced by chemistry, which coupled same factors. Here we used...
Recent studies have remarked on differences in the life cycles of individual fine roots. However, dynamics roots with different cycles, such as ephemeral and perennial, during root system development are still unknown. We examined a mature stand Chamaecyparis obtusa Sieb. et Zucc. (Cupressaceae) using sequential ingrowth core method an anatomical method. The visual classification, i.e., orange, red, brown, intact dead, fragmented corresponded well classification. Orange red contained passage...
The effects of elevated atmospheric nitrogen (N) deposition on N cycling in Japanese forest ecosystems are reviewed here to assess the sensitivity nitrate (NO3−) leaching from forests streams response this deposition. Long-term monitoring throughout Japan suggests that long-range transport air pollutants East Asia accounts for recent increases Japan. A new conceptual model saturation proposes kinetic can be related unavoidable hydrological loss having an Asian monsoon climate with warm and...
We describe a new and easy technique for placing lifting root meshes to estimate fine production in forest ecosystems. The method improves upon previously proposed mesh placement techniques by using sharp stainless steel blade two thin sheets insert more easily accurately the soil, utilizing narrow garden spade lift soil block containing mesh. takes significantly less time than widely used ingrowth core method, causes minimal disturbance requires only simple equipment. detailed documentation...
