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 Current climatic trends involve both increasing temperatures and variability, with extreme events becoming more frequent. Increasing concern on has triggered research vegetation shifts. However, evidences of shifts resulting from these are still relatively rare. Empirical evidence supports the existence stabilizing processes minimizing counteracting effects events, reinforcing community resilience. We propose a demographic framework to understand this inertia change based balance...
The worldwide phenomenon of shrub encroachment in grass-dominated dryland ecosystems is commonly associated with desertification. Studies the purported desertification effects are often restricted to relatively few study areas, and document a narrow range possible impacts upon biota ecosystem processes. We conducted degraded Mediterranean grasslands dominated by Stipa tenacissima simultaneously evaluate on structure composition multiple biotic community components, various indicators...
Abstract Interactions among species determine local‐scale diversity, but local interactions are thought to have minor effects at larger scales. However, quantitative comparisons of the importance biotic relative other drivers rarely made Using a data set spanning 78 sites and five continents, we assessed climate in determining plant diversity alpine ecosystems dominated by nurse‐plant cushion species. Climate variables related with water balance showed highest correlation richness global...
Summary Mountain plants are particularly sensitive to climate warming because snowmelt timing exerts a direct control on their reproduction. Current is leading earlier dates and longer snow‐free periods. Our hypothesis that high‐mountain Mediterranean not able take advantage of lengthened period this leads drought truncates the growing season. However, reproductive may somewhat mitigate these negative effects through temporal shifts. We assessed flowering phenology success Silene ciliata ,...
Germination and seedling establishment, which are critical stages in the regeneration process of plant populations, may be subjected to natural selection adaptive evolution. The aims this work were assess main limitations on offspring performance Silene ciliata, a high mountain Mediterranean plant, test whether local adaptation at small spatial scales has significant effect success establishment. Reciprocal sowing experiments carried out among three populations species for evidence...
Summary Pioneer plants are adapted to grow in unpredictable environments. These have evolved several traits related seed morphology and germination cope with this unpredictability. The main aim of study was investigate the effect plant identity maternal environment on mass Sinapis arvensis . This undertaken S. grown four experimentally manipulated resource availability scenarios: (i) nitrogen addition, (ii) water (iii) simultaneously added, (iv) control. Plants grew under field conditions an...
The monitoring of desertification processes, and particularly the development “early‐warning” systems, is an increasingly important in management drylands. It has been shown that patch size distribution dryland vegetation can be described using power laws deviations from such patterns may used as early‐warning signal for onset desertification. We tested this idea data 29 semiarid steppes located along a latitudinal gradient Spain. A truncated law (TPL) fitted perennial better than all...
Plants from gypsum habitats are classified as gypsophiles and gypsovags. The former include both narrow endemics limited to small areas regionally dominant growing in of large regions, whereas gypsovags plants that can grow non-gypsum soils. Factors controlling the distribution still not fully understood.To assess how different types deal with stressful conditions substrates, comparisons were made leaf chemical composition four gypsovags, five two massive Iberian Peninsula.The was clearly...
Climate change will exacerbate the degree of abiotic stress experienced by semi-arid ecosystems. While profoundly affects biotic interactions, their potential role as modulators ecosystem responses to climate is largely unknown. Using plants and biological soil crusts, we tested relative importance facilitative–competitive interactions other community attributes (cover, species richness evenness) drivers functioning along gradients in Mediterranean Biotic shifted from facilitation...
Gypsum soils are among the most restrictive and widespread substrates for plant life. Plants living on gypsum classified as gypsophiles (exclusive to gypsum) gypsovags (non-exclusive gypsum). The former have been separated into wide narrow gypsophiles, each with a putative different ecological strategy. Mechanisms displayed by plants compete survive still not fully understood. aim of this study was compare main chemical groups in leaves specificity explore ability Fourier transform infrared...
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...
Assessing changes in plant functional traits along gradients is useful for understanding the assembly of communities and their response to global local environmental drivers. However, these may reflect effects species composition (i.e. turnover), abundance interaction), intra-specific trait variability plasticity). In order determine relevance latter, variation can be assessed under minimal turnover. Nine sampling sites were established an altitudinal gradient a Mediterranean high mountain...
Summary Land abandonment due to increasing depopulation of rural areas is an ongoing trend in developed countries worldwide. Abandoned lands represent opportunity for ecosystem recovery, urgent need biodiversity conservation. Seed dispersal services provided by animals are a key feature this process. Different dispersers may differentially contribute plant recruitment under different ecological conditions, leading complementary services. We studied the services, quantified as contribution...
