- Photosynthesis led to a shift from abiotic geomorphic toward biotic biogeomorphic dynamics on the Earth. By converting solar energy into carbohydrates and cellulose, photosynthesis permitted plants to perform geomorphic work through their biomechanical and biochemical impacts on rocks, sediment and soil dynamics.
Dec 26, 2016 · In this study, we asked how the vegetation structure, plant diversity and soil traits differ among the habitats in each plant formation, whether soil characteristics affect vegetation structure and plant diversity and whether the effect of soil varied across different formations.

In the absence of a well-developed catalogue of global soil biodiversity , we initially searched within the PREDICTS database [22, 23] for soil assemblage data, defining soil assemblages as those sampled within the soil; at the soil surface, or in the leaf litter. The database is a global compilation of studies that have each compared non-cultivate...
Using the information in the original papers, each site was classified into one of six categories of land use—primary vegetation, secondary vegetation, plantation forest, cropland, pasture or urban—and either low, medium, or high use intensity (see Additional file 1 and for full definitions). Most combinations of land use and use intensity (hencef...
To offset the geographic bias in soil versus above-ground assemblages (Fig. 1), we applied weights in the models. Weights were calculated by dividing the number of soil sites by the number of above-ground sites within each biome (Additional file 1: Table S2). Weights were calculated separately for the invertebrate-only subset (not shown).
All analyses were carried out in R 3.5.1 . Because total abundance contained non-integers even before rescaling, it was log(x + 1) transformed before modelling with Gaussian errors. The studies in the dataset vary widely in many aspects of sampling. We therefore fitted mixed-effects models (as implemented in lme4 version 1.1.18.1 with bobyqanumeri...
Jun 8, 2005 · Removal of soil and vegetation by landsliding reduces local slopes to a stable threshold gradient. This creates a base level drop for the areas upstream, and depending on the vegetation cover, and storm arrivals, may trigger significant upland erosion.

Dec 23, 2021 · Plant functional traits can predict community assembly and ecosystem functioning and are thus widely used in global models of vegetation dynamics and land–climate feedbacks. Still, we lack a...
Jan 1, 2023 · The colonization of land by plants, accompanied by their morphological, physiological and developmental changes, resulted in plant biodiversity.
Jan 1, 2024 · Mechanisms by which vegetation roots influence the soil structure and soil hydraulic properties are expounded. •. Relationships between soil hydraulic properties and vegetation root parameters are examined. •. Challenges remain in comprehending and quantifying the effects of vegetation roots on soil structure.
Aug 3, 2022 · In this review, we detail how the geophysical environment affects soil formation and evaluate the mechanisms through which edaphic conditions control vegetation structure, floristic diversity and functional diversity.
