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.

The world‐wide ‘fast–slow’ plant economics spectrum: a traits manifesto DOI Open Access

Summary The leaf economics spectrum (LES) provides a useful framework for examining species strategies as shaped by their evolutionary history. However, that spectrum, originally described, involved only two key resources (carbon and nutrients) one of three economically important plant organs. Herein, I evaluate whether the idea can be broadly extended to water – third resource –stems, roots entire plants individual, community ecosystem scales. My overarching hypothesis is strong selection along trait trade‐off axes, in tandem with biophysical constraints, results convergence any taxon on uniformly fast, medium or slow strategy (i.e. rates acquisition processing) all organs resources. Evidence economic spectra exists stems well leaves, traits related carbon nutrients. These apply generally within across scales (within communities, climate zones, biomes lineages). There are linkages coupling among resources, resulting an integrated whole‐plant spectrum. Species capable moving rapidly have low tissue density, short life span high flux at organ individual reverse true strategy. Different may different conditions, but being fast respect requires others, general feature species. Economic influence performance fitness consistent trait‐based theory about underlying adaptive mechanisms. Traits help explain differences growth survival gradients thus distribution assembly communities light, nutrient gradients. scale up associated faster processes such decomposition primary productivity, process rates.

Abstract Worldwide decomposition rates depend both on climate and the legacy of plant functional traits as litter quality. To quantify degree to which differentiation among species affects their rates, we brought together leaf trait mass loss data for 818 from 66 experiments six continents. We show that: (i) magnitude species‐driven differences is much larger than previously thought greater climate‐driven variation; (ii) decomposability a species’ consistently correlated with that ecological strategy within different ecosystems globally, representing new connection between whole carbon biogeochemical cycling. This strategies crucial understanding vegetation–soil feedbacks, improving forecasts global cycle.

Summary Here, we analysed a wide range of literature data on the leaf dry mass per unit area (LMA). In nature, LMA varies more than 100‐fold among species. Part this variation ( c . 35%) can be ascribed to differences between functional groups, with evergreen species having highest LMA, but most is within groups or biomes. When grown in same controlled environment, succulents and woody evergreen, perennial slow‐growing have inherently high LMA. Within studied, high‐LMA show higher tissue densities. However, deciduous result from larger volumes (thickness). Response curves constructed experiments under conditions showed that varied strongly light, temperature submergence, moderately CO 2 concentration nutrient water stress, marginally other conditions.

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.
