Soil life supports the functioning and biodiversity of terrestrial ecosystems. Springtails (Collembola) are among most abundant soil arthropods regulating fertility flow energy through above- belowground food webs. However, global distribution springtail diversity density, how these relate to fluxes remains unknown. Here, using a dataset representing 2470 sites, we estimate total biomass at 27.5 megatons carbon, which is threefold higher than wild vertebrates, record peak densities up 2...
Plant-parasitic nematodes (PPN) are responsible for severe yield losses in crop production. Management is challenging as effective and safe means rare. Recently, it has been discovered that the succinate dehydrogenase (SDH) inhibitor fluopyram highly against PPN while accompanying an excellent safety profile. Here we show a potent of SDH but not mammals, insects earthworm, explaining selectivity on molecular level. As consequence inhibition, impairs ATP generation causes paralysis...
Abstract Ziel der vorliegenden Arbeit ist die Bestimmung Größe und Größenverteilung im nativen Pflanzenmaterial glukosidischen Ketten Cellulose. Zur Gewinnung dieser wird das einer Extraktion mit organischen Lösungsmitteln 2%iger Natronlauge unterworfen anschließend polymeranalog nitriert. Die einzelnen Schritte des präparativen Verfahrens werden Hinblick auf ihre mögliche Abbauwirkung durch Variation sämtlicher Versuchsbedingungen kontrolliert. Es gezeigt, daß angewandte Verfahren...
Insect declines have been discussed intensively among experts, policymakers, and the public. Albeit, decreasing trends reported for a long time various regions in Europe North America, but controversial discussion over role of specific drivers pressures still remains. A reason these uncertainties lies within complex networks inter-dependent biotic abiotic factors as well anthropogenic activities that influence habitats, communities, populations, individual organisms. Many recent publications...
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...
BackgroundEarly detection of an impending flood and the availability countermeasures to deal with it can significantly reduce its health impacts. In developing countries like India, public primary care facilities are frontline organizations that disasters particularly in rural settings. For robust counter reacting systems evaluating preparedness capacities within existing becomes necessary.ObjectiveThe objective study is assess functional capacity system Jagatsinghpur district Orissa India...
Within the scope of Integrated Rhine Program an ecological flood gate and channel was inserted into polder "Ingelheim" to enhance animal plant diversity. In 2008, carabid beetles springtails were collected, using pitfall traps, measure effects flooding a strong precipitation event at flood-disturbed dry location in this area. At both localities, xerophilic mesophilic beetle species dominant throughout study period. The total number individuals hygrophilic comparatively constant, while...
Standard ecological methods (pitfall traps, trunk eclectors and soil cores) were used to evaluate collembolan community responses different flooding intensities. Three sites of a floodplain habitat near Mainz, Germany, with regimes investigated. The structures communities are markedly depending on intensity. Sites more affected by dominated hygrophilic hygrotolerant species, whereas the hardwood is mesophilic species. survival strategies species include egg diapause passive drifting....
Collembola are ancient arthropods living in soil with extensive exposure to dirt, bacteria, and fungi. To protect from the harsh environmental conditions retain a layer of air for breathing when submerged water, they have evolved superhydrophobic, liquid-repelling cuticle surface. The nonfouling self-cleaning properties springtail make it an interesting target biomimetic materials design. Recent research has mainly focused on intricate microstructures at Here we study role chemistry species...

For the European risk assessment (RA) for soil organisms exposed to plant protection products (PPPs) endpoints from ecotoxicological laboratory studies are compared with predicted environmental concentrations in (PECSOIL) at first tier. A safety margin must be met; otherwise, a higher tier RA is triggered (usually organism field studies). new tiered exposure modeling guidance was published by EFSA determine PECSOIL. This work investigates its potential impact on future RA. PECSOIL values >50...
The decline of insects is a global concern, yet identifying the factors behind it remains challenging due to complexity potential drivers and underlying processes, lack quantitative historical data on insect populations. This study assesses 92 in West Germany, where significant declines have been observed. Using from federal statistical offices market surveys, traces changes landscape structure agricultural practices over 33 years. Over years, region underwent major changes, including...
Micro, macro and mesofauna in the soil often respond to fluctuating environmental conditions, resulting changes of abundance community structure. Effects changing parameters are normally determined with samples taken field brought laboratory, i.e. where natural conditions may not apply. We devised a method (STAFD - tubes for artificial flood drought), which simulates hydrological state situ using implanted cores. Control were compared treatment floods 15, 30, 60 90 days, droughts 60, 120...
Abstract The European environmental risk assessment (ERA) of plant protection products follows a tiered approach. approach for soil invertebrates currently consists two steps, starting with Tier 1 based on reproduction toxicity tests earthworms, springtails, and predatory mites. In case an unacceptable is identified at 1, field studies can be conducted as higher‐tier option. For invertebrates, intermediate tiers are not implemented. Hence, there limited possibility to include additional...
Intact soil food webs are pivotal to maintaining essential functions, such as carbon recycling, sequestering, and biomass production. Although the functional role of micro- (e.g., bacteria fungi) macrofauna earthworms) is comparatively well established, importance mesofauna community abundance diversity Acari Collembola) in functionality less clear. We investigated this question a six-month field experiment arable by actively manipulating biodiversity through application two legacy...
