The mechanical reinforcement due to roots against shallow landslides occurs when the fibres intersect the shear surface, usually at depths lower than 2 m. In the literature, the presence of roots is often taken into account by modelling the soil as an equivalent composite material: \u2018the root-permeated soil\u2019, by including an additional cohesion term in the Mohr-Coulomb equation. The models used to estimate the root additional cohesion are presented in the first part of the paper. In some cases, root cohesion is calculated based on the resistant properties of the fibres and assuming an order for the progressive roots failure, either breaking, slipping out or buckling. On the other hand, some authors used structural models of the roots investigating not only the stresses in the roots, but also in the surrounding soil to obtain a better estimation of the root cohesion. In the second part of the paper, the calculation of the root reinforcement is used to assess the safety factor (SF) of the slope. Both Limit Equilibrium analyses (LE) and Finite Element Methods (FEM) are discussed, stressing the limitations of both the approaches.", "keywords": ["Root mechanical reinforcement", "[SDE.BE] Environmental Sciences/Biodiversity and Ecology", "Root cohesion", "Slope stability", "[SDV.BID.SPT] Life Sciences [q-bio]/Biodiversity/Systematics", " Phylogenetics and taxonomy", "Shallow landslides", "[SDV.EE.ECO] Life Sciences [q-bio]/Ecology", " environment/Ecosystems", "0211 other engineering and technologies", "02 engineering and technology", "15.

Les esp\u00e8ces d'arbres associ\u00e9es aux champignons AM pr\u00e9sentaient une forte proportion de bact\u00e9ries copiotrophes et de champignons saprotrophes, tandis que les arbres associ\u00e9s aux champignons ECM pr\u00e9sentaient une abondance relative \u00e9lev\u00e9e de bact\u00e9ries oligotrophes, de champignons ECM et de n\u00e9matodes fongivores. Les diff\u00e9rentes abondances de ces groupes fonctionnels soutiennent l'\u00e9conomie nutritive plus inorganique des esp\u00e8ces d'arbres AM par rapport \u00e0 l'\u00e9conomie nutritive plus organique des esp\u00e8ces d'arbres ECM.

Characterizing physico-chemical properties of dust-emitting sediments in arid regions is fundamental to understand the effect of dust on climate and ecosystems. For high-latitude dust (HLD), this knowledge is scarce. This study focuses on the particle size distribution (PSD), mineralogy, cohesion, iron (Fe) mode of occurrence and Visible Near Infra-Red (VNIR) reflectance spectra of dust-emitting sediments from dust-hotspots in Iceland (HLD region). Extensive analysis was conducted on top sediments collected from seven dust-sources and an intensive at Jokuls\u00e1 basin including top sediments, sediments and aeolian ripples. Fully and minimally dispersed PSDs evidenced remarkable similarities with an average median diameter of 56\u00b169 and 55\u00b162 \u00b5m. Mineralogical analyses showed the prevalence of amorphous phases (68\u00b126 %), feldspars (17\u00b113 %), and pyroxenes (9.3\u00b17.2 %), aligned with the reflectance spectra. Fe content reached 9.5\u00b10.40 wt %, mainly in silicate structures (80\u00b16.3 %), complemented by magnetite (16\u00b15.5 %), hematite/goethite (4.5\u00b12.7 %), and readily exchangeable Fe-ions or Fe nano-oxides (1.6\u00b10.63 %). Icelandic top sediments have coarser PSD compared to the high dust-emitting crusts from mid-latitude arid regions, distinctive mineralogy, and threefold bulk Fe content, with a large presence of magnetite. The congruence between fully and minimally dispersed PSDs underscores a reduced particle aggregation and cohesion of Icelandic top sediments, suggesting that aerodynamic entrainment of dust may also play a role upon emission in this region, aside of saltation bombardment. The analysis of an extensive sampling in Dyngjusandur allowed this study to present a conceptual model to encapsulate Iceland's rapidly evolving high dust-emitting environments.</p></article>", "keywords": ["550", "QC1-999", "Iron", "Iceland", "Reflectance", "http://metadata.un.org/sdg/3", "01 natural sciences", "\u00c0rees tem\u00e0tiques de la UPC::Desenvolupament hum\u00e0 i sostenible::Enginyeria ambiental", "Make cities and human settlements inclusive", " safe", " resilient and sustainable", "Physicochemical property", "11.
