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....
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...
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...
In the last decades, there has been a growing interest on evaluating effects of biological soil crusts (hereafter, biocrusts) vascular plants. The purpose this paper was to investigate influence biocrusts Stipa tenacissima, key species in arid and semi-arid environments Mediterranean Basin. fact, we explored impact removal underneath S. tenacissima chemical properties leaf mineral uptake. Indeed, studied effect mixed seed germination under laboratory conditions. research showed greater...
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...
Studying relationships of plant traits to ecosystem properties is an emerging approach aiming understand plant's potential effect on functioning. In the current study, we explored links between morphological and nutritional leaf two Mediterranean perennial grass species Stipa tenacissima Lygeum spartum, widely used prevent desertification process by stabilizing sand dunes. We evaluated also in terms nitrogen (N) phosphorus (P) availability leaves investigated corresponding soil. Our results...
Abstract The interest of the scientific community in biological soil crusts has grown exponentially over last decades. One research interests is study effect these on plant establishment. Findings this topic have been controversial, and some differences were attributed to crust types. Biological dominated by lichens are common components Stipa tenacissima steppes arid semi‐arid environments southern Mediterranean. In current study, we conducted growth chamber experiments investigate...
