Experiments suggest that biodiversity enhances the ability of ecosystems to maintain multiple functions, such as carbon storage, productivity, and buildup nutrient pools (multifunctionality). However, relationship between multifunctionality has never been assessed globally in natural ecosystems. We report here on a global empirical study relating plant species richness abiotic factors drylands, which collectively cover 41% Earth's land surface support over 38% human population....
Soil bacteria and fungi play key roles in the functioning of terrestrial ecosystems, yet our understanding their responses to climate change lags significantly behind that other organisms. This gap is particularly true for drylands, which occupy ∼41% Earth´s surface, because no global, systematic assessments joint diversity soil have been conducted these environments date. Here we present results from a study across 80 dryland sites all continents, except Antarctica, assess how changes...
Summary We used a functional trait‐based approach to assess the impacts of aridity and shrub encroachment on structure Mediterranean dryland communities (functional diversity ( FD ) community‐weighted mean trait values CWM )), evaluate how these attributes ultimately affect multifunctionality (i.e. provision several ecosystem functions simultaneously). Shrub (the increase in abundance/cover shrubs) is major land cover change that taking place grasslands worldwide. Studies conducted drylands...
Abstract Intransitive competition networks, those in which there is no single best competitor, may ensure species coexistence. However, their frequency and importance maintaining diversity real‐world ecosystems remain unclear. We used two large data sets from drylands agricultural grasslands to assess: (1) the generality of intransitive competition, (2) intransitivity–richness relationships (3) effects major drivers biodiversity loss (aridity land‐use intensification) on intransitivity...
Grazing represents the most extensive use of land worldwide. Yet its impacts on ecosystem services remain uncertain because pervasive interactions between grazing pressure, climate, soil properties, and biodiversity may occur but have never been addressed simultaneously. Using a standardized survey at 98 sites across six continents, we show that soil, are critical to explain delivery fundamental drylands Increasing pressure reduced service in warmer species-poor drylands, whereas positive...
Summary Habitat filtering ( HF , trait convergence) and niche differentiation ND divergence) are known to impact upon plant community structure. Both processes integrate individual responses the abiotic environment biotic interactions. Thus, it is difficult clearly identify underlying factors that ultimately structure by looking at community‐level patterns of divergence or convergence alone. We used a functional trait‐based multiscale approach assess how interactions aridity determine...
Abstract Aim Geographical, climatic and soil factors are major drivers of plant beta diversity, but their importance for dryland communities is poorly known. The aim this study was to: (1) characterize patterns diversity in global drylands; (2) detect common environmental diversity; (3) test thresholds conditions driving potential shifts species composition. Location Global. Methods Beta quantified 224 from 22 geographical regions on all continents except Antarctica using four complementary...
Abstract Multiple ecosystem functions need to be considered simultaneously manage and protect the several services that are essential people their environments. Despite this, cost effective, tangible, relatively simple globally relevant methodologies monitor in situ soil multifunctionality, is, provision of multiple by soils, have not been tested at global scale. We combined correlation analysis structural equation modelling explore whether we could find easily measured, field‐based...
While much is known about the factors that control each component of terrestrial nitrogen (N) cycle, it less clear how these affect total N availability, sum organic and inorganic forms potentially available to microorganisms plants. This particularly true for N-poor ecosystems such as drylands, which are highly sensitive climate change desertification processes can lead loss soil nutrients N. We evaluated different climatic, abiotic, plant nutrient related correlate with availability in...
Abstract Aims Climate and human impacts are changing the nitrogen ( N ) inputs losses in terrestrial ecosystems. However, it is largely unknown how these two major drivers of global change will simultaneously influence cycle drylands, largest biome on planet. We conducted a observational study to evaluate aridity impacts, together with biotic abiotic factors, affect key soil variables cycle. Location Two hundred twenty‐four dryland sites from all continents except A ntarctica widely...
Increases in the abundance of woody species have been reported to affect provisioning ecosystem services drylands worldwide. However, it is virtually unknown how multiple biotic and abiotic drivers, such as climate, grazing, fire, interact determine dominance across global drylands. We conducted a standardized field survey 304 plots 25 countries assess climatic features, soil properties, fire dryland rangelands. Precipitation, temperature, grazing were key determinants tree shrub dominance....
Over the last decades, there has been a growing interest in evaluating predicted potential impacts of future climatic conditions on ecosystem functioning. Ecological indicators developed to assess functioning strongly rely soil and vegetation variables. In current investigation, we evaluated structural functional status southern Mediterranean Stipa tenacissima steppe along an increasing aridity gradient. We estimated also effects their The wide variation LFA indices, attributes properties...
North African steppes are subjected to extreme degradation resulting in the reduction of their surface, genetic erosion resources, and decrease biodiversity. Stipa tenacissima steppes, which constitute one most representative vegetation types driest areas Mediterranean basin, continuously degrading. With aim contributing a better knowledge floristic composition diagnosing state these we conducted phytoecological analysis 10 S. sites Tunisia. Floristic inventory compiled systematic list 46...
