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.

Root traits as drivers of plant and ecosystem functioning: current understanding, pitfalls and future research needs

New Phytologist, Год журнала: 2020, Номер 232(3), С. 1123 - 1158

Summary The effects of plants on the biosphere, atmosphere and geosphere are key determinants terrestrial ecosystem functioning. However, despite substantial progress made regarding plant belowground components, we still only beginning to explore complex relationships between root traits functions. Drawing literature in physiology, ecophysiology, ecology, agronomy soil science, reviewed 24 aspects functioning their with a number system traits, including architecture, morphology, anatomy, chemistry, biomechanics biotic interactions. Based this assessment, critically evaluated current strengths gaps our knowledge, identify future research challenges field ecology. Most importantly, found that broadest importance not those most commonly measured. Also, estimation trait relative for requires us consider more comprehensive range functionally relevant from diverse species, across environments over time series. We also advocate establishing causal hierarchical links among will provide hypothesis‐based framework parsimonious sets strongest functions, link genotypes

A starting guide to root ecology: strengthening ecological concepts and standardising root classification, sampling, processing and trait measurements

New Phytologist, Год журнала: 2021, Номер 232(3), С. 973 - 1122

Summary In the context of a recent massive increase in research on plant root functions and their impact environment, ecologists currently face many important challenges to keep generating cutting‐edge, meaningful integrated knowledge. Consideration below‐ground components ecosystem studies has been consistently called for decades, but methodology is disparate sometimes inappropriate. This handbook, based collective effort large team experts, will improve trait comparisons across integration information databases by providing standardised methods controlled vocabularies. It meant be used not only as starting point students scientists who desire working ecosystems, also experts consolidating broadening views multiple aspects ecology. Beyond classical compilation measurement protocols, we have synthesised recommendations from literature provide key background knowledge useful for: (1) defining entities giving keys dissection, classification naming beyond fine‐root vs coarse‐root approach; (2) considering specificity produce sound laboratory field data; (3) describing typical, overlooked steps studying roots (e.g. handling, cleaning storage); (4) gathering metadata necessary interpretation results reuse. Most importantly, all traits introduced with some degree ecological that foundation understanding meaning, typical use uncertainties, methodological conceptual perspectives future research. Considering this, urge readers solely extract protocol measurements this work, take moment read reflect extensive contained broader guide ecology, including sections I–VII introductions each section description. Finally, it critical understand major aim help break down barriers between subdisciplines ecology ecophysiology, broaden researchers’ study create favourable conditions inception comprehensive experiments role functioning.

Climate, soil and plant functional types as drivers of global fine‐root trait variation

Journal of Ecology, Год журнала: 2017, Номер 105(5), С. 1182 - 1196

Summary Ecosystem functioning relies heavily on below‐ground processes, which are largely regulated by plant fine‐roots and their functional traits. However, our knowledge of fine‐root trait distribution to date local‐ regional‐scale studies with limited numbers species, growth forms environmental variation. We compiled a world‐wide dataset, featuring 1115 species from contrasting climatic areas, phylogeny test series hypotheses pertaining the influence types, soil climate variables, degree manipulation growing conditions Most particularly, we tested competing that traits typical faster return investment would be most strongly associated limiting versus favourable resource availability. accounted for both data source phylogenetic relatedness. demonstrate that: (i) Climate promoting fertility relate negatively favouring fast acquisition, particularly strong positive effect temperature diameter negative specific root length ( SRL ), rainfall nitrogen concentration; (ii) Soil bulk density influences morphology, thicker, denser fine‐roots; (iii) Fine‐roots herbaceous average finer have higher than those woody N 2 ‐fixing capacity positively relates nitrogen; (iv) Plants in pots grown field. Synthesis . This study reveals large variation encountered globally relevance several key types variables explaining substantial part this Climate, temperature, were two strongest predictors High occurred at local scales, suggesting wide‐ranging economics strategies viable within areas conditions.

An integrated framework of plant form and function: the belowground perspective

New Phytologist, Год журнала: 2021, Номер 232(1), С. 42 - 59

Опубликована: Июль 2, 2021

Summary Plant trait variation drives plant function, community composition and ecosystem processes. However, our current understanding of disproportionately relies on aboveground observations. Here we integrate root traits into the global framework form function. We developed tested an overarching conceptual that integrates two recently identified gradients with a well‐established framework. confronted novel published relationships between above‐ belowground analogues multivariate analyses 2510 species. Our represent leaf conservation (specific area, nitrogen concentration, tissue density), collaboration gradient (root diameter specific length) size (plant height rooting depth). found integrated, whole‐plant space required as much four axes. The main axes represented fast–slow ‘conservation’ which fine‐root were well aligned, ‘collaboration’ in roots. additional separate, orthogonal for depth. This perspective multidimensional nature better encompasses function influence surrounding environment.

A worldview of root traits: the influence of ancestry, growth form, climate and mycorrhizal association on the functional trait variation of fine‐root tissues in seed plants

New Phytologist, Год журнала: 2017, Номер 215(4), С. 1562 - 1573

Fine-root traits play key roles in ecosystem processes, but the drivers of fine-root trait diversity remain poorly understood. The plant economic spectrum (PES) hypothesis predicts that leaf and root evolved coordination. Mycorrhizal association type, growth form climate may also affect traits. However, extent to which these controls are confounded with phylogenetic structuring remains unclear. Here we compiled information about for > 600 species. Using relatedness, climatic ranges, mycorrhizal associations, quantified importance factors global distribution Phylogenetic accounts most variation all excepting tissue density, diameter nitrogen concentration showing strongest signal specific length intermediate values. Climate was second important factor, whereas type had little effect. Substantial coordination occurred between leaves roots, strength varied forms clades. Our analyses provide evidence integration roots PES requires better accounting across Inclusion provides a powerful framework predictions belowground functional at scales.
