Continental-scale assessments of 21st century global impacts climate change on biodiversity have forecasted range contractions for many species. These coarse resolution studies are, however, limited relevance projecting risks to in mountain systems, where pronounced microclimatic variation could allow species persist locally, and are ill-suited assessment species-specific threat particular regions. Here, we assess the 2632 plant across all major European ranges, using high-resolution (ca....
1 Ecological and agronomic research suggests that increased crop diversity in species-poor intensive systems may improve their provision of ecosystem services. Such general predictions can have critical importance for worldwide food production agricultural practice but are largely untested at higher levels diversity. 2 We propose new methodology the design analysis experiments to quantify diversity-function relationships. Our relative strength inter-specific interactions contribute a...
Summary A coordinated continental‐scale field experiment across 31 sites was used to compare the biomass yield of monocultures and four species mixtures associated with intensively managed agricultural grassland systems. To increase complementarity in resource use, each experimental design represented a distinct functional type derived from two levels traits, nitrogen acquisition ( N 2 ‐fixing legume or nonfixing grass) crossed temporal development (fast‐establishing temporally persistent)....
Abstract Current challenges to global food security require sustainable intensification of agriculture through initiatives that include more efficient use nitrogen (N), increased protein self‐sufficiency homegrown crops, and reduced N losses the environment. Such were addressed in a continental‐scale field experiment conducted over 3 years, which amount total yield (N tot ) gain mixtures as compared grass monocultures gainmix was quantified from four‐species grass–legume stands with greatly...
A better understanding of the role plant composition and N cycle on agroecosystems is necessary, as these will be affected by future developments in agriculture intensification. To explore effect diversity yield carbon (C) nitrogen (N) balances forage mixtures, identifying potential co-benefits between functions. We analyzed results from a field experiment where plants three species (a grass, legume, non-legume forb) were cultivated monocultures mixtures. Three years after sward...
Different components of biodiversity may vary independently each other along environmental gradients giving insights into the mechanisms that regulate species coexistence. In particular, functional diversity (FD) or presence rare endemic in natural assemblages do not necessarily increase with diversity. We studied if different plant (species richness, Simpson diversity, evenness) varied similarly to FD (measured as a generalization index) and rarity grazing intensity climatic gradients....
Abstract Questions: Trait differentiation among species occurs at different spatial scales within a region. How does the partitioning of functional diversity help to identify community assembly mechanisms? Location: Northeastern Spain. Methods: Functional can be partitioned into within‐community (α) and among‐communities (β) components, in analogy Whittaker's classical α β concept. In light ecological null models, we test discuss two algorithms as framework measure (the Rao quadratic entropy...
Summary In the face of large‐scale environmental changes, predicting consequences for species composition from species’ traits can be a major step towards generalizing ecological patterns and management. Few studies, however, have explored applicability this tool in relation to different climatic conditions. Here, changes along gradient sheep‐grazing pressure (high, low, abandonment) were used test whether common set plant functional (PFT) would provide consistent predictions responses...
We develop a modeling framework that estimates the effects of species identity and diversity on ecosystem function permits prediction diversity–function relationship across different types community composition. Rather than just measure an overall effect diversity, we separately estimate contributions interactions. This is especially important when both positive negative interactions occur or where there are patterns in Based biological assumptions, can test for interaction correspond to...
In this study we examined ecosystem respiration (RECO) data from 104 sites belonging to FLUXNET, the global network of eddy covariance flux measurements. The goal was identify main factors involved in variability RECO: temporally and between as affected by climate, vegetation structure plant functional type (PFT) (evergreen needleleaf, grasslands, etc.). We demonstrated that a model using only climate drivers predictors RECO failed describe part temporal dependency on gross primary...
Abstract Question Many functional diversity indices require the calculation of trait dissimilarities between species. However, very little is known about how dissimilarity measure used might affect conclusions ecological processes drawn from diversity. Methods We simulated real applications diversity, to illustrate key properties two most common families measures: (1) ‘Gower’ distance, using only ‘mean trait’ value per species and then standardizing each trait, e.g. relative its range; (2)...
Questions: What are the relative roles of abiotic and grazing management factors on plant community distribution in landscapes? How livestock type stocking rate related to changes vegetation structure composition? Location: Sub‐alpine grasslands central eastern Pyrenees. Methods: Multivariate analysis variance partitioning methods were used evaluate environmental structuring composition diversity patterns three surveys differently managed grasslands. Results: Vegetation within a region was...
Abstract Questions: Does grazing have the same effect on plant species richness at different spatial scales? of scale vary under climatic conditions and vegetation types? slope species-area curve change with intensity similarly Location: Pastures along a gradient in northeastern Spain. Methods: In zones regimes sheep (high-, low-pressure, abandonment), was measured plot sizes (from 0.01 to 100 m2) curves calculated. The study replicated five locations from lowland semi-arid rangelands upland...

Abstract Grassland diversity can support sustainable intensification of grassland production through increased yields, reduced inputs and limited weed invasion. We report the effects on suppression from 3 years a 31‐site continental‐scale field experiment. At each site, 15 communities comprising four monocultures 11 four‐species mixtures based wide range species' proportions were sown at two densities managed by cutting. Forage species selected according to crossed functional traits, “method...
Abstract Biogeochemical cycling of elements largely occurs in dissolved state, but many may also be bound to natural nanoparticles (NNP, 1–100 nm) and fine colloids (100–450 nm). We examined the hypothesis that size composition stream water NNP vary systematically across Europe. To test this hypothesis, 96 samples were simultaneously collected 26 forested headwater catchments along two transects Three fractions (~1–20 nm, >20–60 >60 identified with Field Flow Fractionation coupled...

These communities are considered to be especially vulnerable climate change because their position at south‐western edge semi‐natural grassland biome Europe. Changes patterns above‐ below‐ground biomass assessed for different plant guilds two experiments, which turves transplanted from upland lowland locations. first experiment aimed evaluate general responses...
Summary Increased species diversity promotes ecosystem function; however, the dynamics of multi‐species grassland systems over time and their role in sustaining higher yields generated by increased are still poorly understood. We investigated development species’ relative abundances mixtures 3 years to identify drivers change links yield effects. A continental‐scale field experiment was conducted at 31 sites using 11 different four‐species each sown two seed abundances. The four consisted...
