Understanding the influence of environment on functional structure ecological communities is essential to predict response biodiversity global change drivers. Ecological theory suggests that multiple environmental factors shape local species assemblages by progressively filtering from regional pool communities. These successive filters should various components community in different ways. In this paper, we tested relative metrics plant trait (i.e. ‘community weighted mean trait’ and diversity, i.e. richness, evenness divergence) 82 vegetation plots Guisane Valley, French Alps. For 211 sampled measured traits known capture key aspects strategies amongst vascular species, leaf traits, height seed mass (LHS). A comprehensive information framework, together with null model based resampling techniques, was used test effects. Particular responded differently gradients, especially concerning spatial scale at which seem operate. Environmental acting a large (e.g. temperature) were found predominantly values, while fine‐scale (topography soil characteristics) mostly influenced diversity distribution values among dominant species. Our results emphasize hierarchical nature forces shaping assemblage: large‐scale having primary effect, selecting adapted site, then finer scales determining abundances coexistence. This will respond change, so predicting responses require multi‐facet approach.

In its simplest definition, a trait is surrogate of organismal performance, and this meaning the term has been used by evolutionists for long time. Over last three decades, developments in community ecosystem ecology have forced concept beyond these original boundaries, trait‐based approaches are now widely studies ranging from level organisms to that ecosystems. Despite some attempts fix terminology, especially plant ecology, there currently high degree confusion use, not only “trait” itself, but also underlying concepts it refers to. We therefore give an unambiguous definition trait, with particular emphasis on functional trait. A hierarchical perspective proposed, extending “performance paradigm” ecology. “Functional traits” defined as morpho‐physio‐phenological traits which impact fitness indirectly via their effects growth, reproduction survival, components individual performance. finally present integrative framework explaining how changes values due environmental variations translated into may influence processes at higher organizational levels. argue can be achieved developing “integration functions” grouped response (community level) effect (ecosystem algorithms.

Plant functional traits are the features (morphological, physiological, phenological) that represent ecological strategies and determine how plants respond to environmental factors, affect other trophic levels influence ecosystem properties. Variation in plant traits, trait syndromes, has proven useful for tackling many important questions at a range of scales, giving rise demand standardised ways measure ecologically meaningful traits.

Abstract Plant traits – the morphological, anatomical, physiological, biochemical and phenological characteristics of plants their organs determine how primary producers respond to environmental factors, affect other trophic levels, influence ecosystem processes services provide a link from species richness functional diversity. Trait data thus represent raw material for wide range research evolutionary biology, community ecology biogeography. Here we present global database initiative named TRY, which has united plant trait worldwide gained an unprecedented buy‐in data: so far 93 databases have been contributed. The repository currently contains almost three million entries 69 000 out world's 300 species, with focus on 52 groups characterizing vegetative regeneration stages life cycle, including growth, dispersal, establishment persistence. A first analysis shows that most are approximately log‐normally distributed, widely differing ranges variation across traits. Most is between (interspecific), but significant intraspecific also documented, up 40% overall variation. types (PFTs), as commonly used in vegetation models, capture substantial fraction observed several occurs within PFTs, 75% In context models these would better be represented by state variables rather than fixed parameter values. improved availability unified expected support paradigm shift trait‐based ecology, offer new opportunities synthetic enable more realistic empirically grounded representation terrestrial Earth system models.

Abstract Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, influence ecosystem properties their benefits detriments people. trait data thus represent the basis for a vast area research spanning from evolutionary biology, community functional ecology, biodiversity conservation, landscape management, restoration, biogeography earth system modelling. Since its foundation in 2007, TRY database plant traits has grown continuously. It now provides unprecedented coverage under an open access policy is main used by worldwide. Increasingly, also supports new frontiers trait‐based research, including identification gaps subsequent mobilization or measurement data. To support this development, article we evaluate extent compiled analyse emerging patterns representativeness. Best species achieved categorical traits—almost complete ‘plant growth form’. However, most relevant ecology vegetation modelling are characterized continuous intraspecific variation trait–environmental relationships. These have be measured on individual respective environment. Despite coverage, observe humbling lack completeness representativeness these many aspects. We, therefore, conclude that reducing biases remains key challenge requires coordinated approach measurements. This can only collaboration with initiatives.

1 Interpreting the functional diversity of vegetation is important in unravelling relationship between environmental change, community composition and ecosystem processes. Functional range distribution trait values a community. It can be described, among other indicators, by community-level weighted means (CWM) divergence. Standard methods exist for measurements but not assessments CWM divergence field. No research has addressed effects different estimating relative abundances, nor need to estimate traits at individual, population or species level, whether could used that bypass taxonomy all together. 2 This study reviews evaluates plot-level assessment herbaceous vegetation.
