Globally invariant metabolism but density-diversity mismatch in springtails.

Soil life supports the functioning and biodiversity of terrestrial ecosystems. Springtails (Collembola) are among the most abundant soil arthropods regulating soil fertility and flow of energy through above- and belowground food webs. However, the global distribution of springtail diversity and density, and how these relate to energy fluxes remains unknown. Here, using a global dataset representing 2470 sites, we estimate the total soil springtail biomass at 27.5 megatons carbon, which is threefold higher than wild terrestrial vertebrates, and record peak densities up to 2 million individuals per square meter in the tundra. Despite a 20-fold biomass difference between the tundra and the tropics, springtail energy use (community metabolism) remains similar across the latitudinal gradient, owing to the changes in temperature with latitude. Neither springtail density nor community metabolism is predicted by local species richness, which is high in the tropics, but comparably high in some temperate forests and even tundra. Changes in springtail activity may emerge from latitudinal gradients in temperature, predation and resource limitation in soil communities. Contrasting relationships of biomass, diversity and activity of springtail communities with temperature suggest that climate warming will alter fundamental soil biodiversity metrics in different directions, potentially restructuring terrestrial food webs and affecting soil functioning

Global fine-resolution data on springtail abundance and community structure

Springtails (Collembola) inhabit soils from the Arctic to the Antarctic and comprise an estimated ~32% of all terrestrial arthropods on Earth. Here, we present a global, spatially-explicit database on springtail communities that includes 249,912 occurrences from 44,999 samples and 2,990 sites. These data are mainly raw sample-level records at the species level collected predominantly from private archives of the authors that were quality-controlled and taxonomically-standardised. Despite covering all continents, most of the sample-level data come from the European continent (82.5% of all samples) and represent four habitats: woodlands (57.4%), grasslands (14.0%), agrosystems (13.7%) and scrublands (9.0%). We included sampling by soil layers, and across seasons and years, representing temporal and spatial within-site variation in springtail communities. We also provided data use and sharing guidelines and R code to facilitate the use of the database by other researchers. This data paper describes a static version of the database at the publication date, but the database will be further expanded to include underrepresented regions and linked with trait data.</p

Naissance d'un patronat "responsable et engagé". L'économie sociale et solidaire en quête de représentativité patronale

International audienceDepuis 2017, l’Union des employeurs de l’économie sociale et solidaire (UDES) est reconnue comme confédération patronale représentative au niveau « multiprofessionnel » et a la capacité de signer des accords nationaux sur le champ de l’économie sociale et solidaire qui regroupe 2,3 millions des salariés. Cette organisation a réussi à s’imposer, comme nouvelle venue, dans le club très fermé des organisations patronales françaises. Comment cette organisation a réussi ce tour de force et à quel prix ? Pour le comprendre, cet article revient sur la genèse de cette organisation patronale, sur les différentes étapes de son développement et son actualité

Le projet de l'économie sociale et solidaire : fonder une économie acapitaliste

National audienceUn grand nombre d’associations font partie du secteur de l’« économie sociale et solidaire » (ESS) par leurs objectifs et par leurs modes d’organisation. Dans cet entretien, Jean-François Draperi, rédacteur en chef de la Revue internationale d’économie sociale (Recma) et directeur du Centre d’économie sociale travail et société au Cnam, propose de clarifier ce qu’est et n’est pas l’ESS, en regard notamment de l’organisation capitaliste et de l’entrepreneuriat social. Il voit dans les formats associatifs et coopératifs de l’ESS des outils majeurs de la démocratisation d’une économie affranchie du capitalisme

A 2D model for coupled heat, air, and moisture transfer through porous media in contact with air channels

International audienceDetailed modelling of air leakage paths through complex building wall assemblies is a challenging task. It requires transient modelling of diffusion and advection phenomena through fluid and solid domains, including porous materials and air channels. In this article, the development of a numerical model coupling heat air and moisture transfers (commonly called HAM transfers) is presented. The model is able to deal with nonisothermal air flow through complex 2D (two-dimensional) geometries, combining air channels and porous media, air permeable or not. A stepwise 1D validation of the model is achieved with numerical benchmarks. The model is then tested on a 2D air leakage configuration subjected to infiltration and exfiltration scenarii
