Summary Roots are assumed to play a major role in structuring soil microbial communities, but most studies exploring the relationships between microbes and plants at community level have only used aboveground plant distribution as proxy. However, decoupling belowground components may occur due differential spreading of canopies root systems. Thus, microbe–plant links not completely understood. Using combination DNA metabarcoding spatially explicit sampling neighbourhood scale, we assessed...
Abstract Inspired by grassland biodiversity experiments studying the impact of plant diversity on primary productivity, Crop Diversity Experiment setup in 2018 aimed at testing whether these benefits also hold for annual crop systems and mixtures achieved transgressive overyielding, i.e. yield mixture that was higher than most productive monoculture. The first 3 years experiment demonstrated do not only increase compared with an average monoculture but often highest yielding effects were...
Most work on plant community ecology has been performed above ground, neglecting the processes that occur in soil. DNA metabarcoding, which multiple species are computationally identified bulk samples, can help to overcome logistical limitations involved sampling communities belowground. However, a major limitation of this methodology is quantification species' abundances based percentage sequences assigned each taxon. Using root tissues five dominant semi-arid Mediterranean shrubland...
Characterizing functional trait variation and covariation, its drivers, is critical to understand the response of species changing environmental conditions. Evolutionary factors determine how traits vary among within at multiple scales. However, disentangling their relative contribution challenging a comprehensive trait-environment framework addressing such questions missing in lichens. We investigated nine related photosynthetic performance, water use nutrient acquisition applying...
Habitat fragmentation is a major driver of global change that has operated historically on Mediterranean ecosystems. However, more needs to be understood about how influences ecological interactions, particularly pollination. Gypsum outcrops are fragmented habitats and settings for the evolution many endangered soil-specialist plants with narrow ranges. In this study, we aimed determine (area connectivity) affects: (i) pollinator community composition (ii) structural properties pollination...
Abstract Higher plant species diversity decreases variability of community productivity. The stabilizing effect can result from species‐specific responses to environmental fluctuations and shifts in competitive hierarchies. Evolutionary adaptation surrounding could further decrease productivity variability. We used a three‐year dataset crop experiment with seven assess the selection history on temporal yield. found contrasting patterns variability: Yield varied more mixtures than...
Abstract Questions How do phylogenetic and functional trait dispersions respond to multiple abiotic gradients? Are coupled across different spatial scales? Does signal on data help elucidate the degree which information is providing novel information? Location Three massifs in mediterranean‐type climate zone of high Andes, central Chile. Methods We sampled plant species composition 20 alpine sites above tree line at three scales: plot (20 m × m), subplot (2.4 2.4 m) cell (30 cm 30 cm)....
Mountains are considered excellent natural laboratories for studying the determinants of plant diversity at contrasting spatial scales. To gain insights into how is structured different scales, we surveyed high mountain communities in Chilean Andes where man-driven perturbations rare. This was done along elevational gradients located latitudes taking account factors that act fine including abiotic (potential solar radiation and soil quality) biotic (species interactions) factors, considering...

Además, excelentes polinizadores y aportan numerosos servicios ecosistémicos fundamentales para mayoría ecosistemas terrestres. Debido a los diversos cambios ambientales inducidos por el ser humano, existen evidencias del declive algunas sus poblaciones ciertas especies. Sin embargo, conocemos muy poco estado conservación muchas ellas ignoramos cuál es su distribución En este trabajo...
In the rubber extraction process, guayule leaves represent an important biomass waste by-product, up to 32%, whose exploitation might contribute valorization of whole plant. The any its bioactive compounds or use as antioxidant seems be most feasible alternative. This study relates morphology individual content 35 (of 50 tentatively identified), determination overall phenolic and activity. morphological traits allowed classification accessions (27) into three main groups according size shape...
Abstract Despite decades of research, a comprehensive understanding trait coordination at the whole‐plant level remains elusive. Furthermore, while link between above‐ground growth rates and leaf traits related to nutrient use is well established, much less known about below‐ground compartment. Herbs woody species exhibit distinct nutrient‐use strategies, but whether these differences extend root unclear. We carried out common garden experiment with 23 perennials (7 herbs 16 species)...
Trait‐based ecology suggests that abiotic filtering is the main mechanism structuring regional species pool in different subsets of habitat‐specific species. At more local spatial scales, other ecological processes may add on giving rise to complex patterns functional diversity (FD). Understanding how assembly operating pools produce locally observed plant assemblages an ongoing challenge. Here, we evaluated importance community alpine fellfield, assessing its effects trait FD. Using...
Understanding how functional and phylogenetic patterns vary among scales along ecological gradients within a given species pool is critical for inferring community assembly processes. However, we lack clear understanding of these in stressful habitats such as Mediterranean high mountains where ongoing global warming expected to affect fitness interactions, subsequently turnover. In this study, investigated 39 grasslands with the same type plant very little turnover across an elevation...

Arbuscular mycorrhizal (AM) fungi enhance the uptake of water and minerals by plant hosts, alleviating stress. Therefore, AM fungal-plant interactions are particularly important in drylands other stressful ecosystems. We aimed to determine combined independent effects above- below-ground community attributes (i.e. diversity composition), soil heterogeneity spatial covariates on structure fungal communities a semiarid Mediterranean scrubland. Furthermore, we evaluated how phylogenetic...
Abstract Specialization remains as a controversial and ambiguous term in ecology. Although it has been usually measured using dichotomic simplified classification of specialists generalists , its nature is by far more complex. In the context biotic interactions, assigning these two labels based on number interacting partners (one or few vs. many). Here, we provide precise, quantitative, objective interpretation specialization phenomenon combining three different dimensions ( specificity...
In alpine ecosystems, greater overlap in flowering phenology among species at higher elevations could be due to evolutionary convergence lineages or environmental filtering for taxa preadapted colder conditions. We hypothesize that the of high communities, subjected and shorter reproductive seasons, is result strong selective pressure imposed by environment rather than conservated traits. To test this hypothesis, we analyzed phylogenetic signal first date, peak duration thermal sums...
