Collaboration broadens the “root economics space” ranging from “do-it-yourself” to “outsourcing” mycorrhizal partners.
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,...
Variation and tradeoffs within among plant traits are increasingly being harnessed by empiricists modelers to understand predict ecosystem processes under changing environmental conditions. While fine roots play an important role in functioning, fine-root underrepresented global trait databases. This has hindered efforts analyze variation link it with function conditions at a scale. Viewpoint addresses the need for centralized database, introduces Fine-Root Ecology Database (FRED,...
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...
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,...
The root economics spectrum (RES), a common hypothesis postulating tradeoff between resource acquisition and conservation traits, is being challenged by conflicting relationships diameter, tissue density (RTD) nitrogen concentration (RN). Here, we analyze global trait dataset of absorptive roots for over 800 plant species. For woody species (but not non-woody species), find nonlinear diameter RTD RN, which stem from the allometric relationship stele cortical tissues. These explain how...
Abstract Motivation Trait data are fundamental to the quantitative description of plant form and function. Although root traits capture key dimensions related responses changing environmental conditions effects on ecosystem processes, they have rarely been included in large‐scale comparative studies global models. For instance, remain absent from nearly all that define spectrum Thus, overcome conceptual methodological roadblocks preventing a widespread integration trait into analyses we...
Deadwood is a large global carbon store with its size partially determined by biotic decay. Microbial wood decay rates are known to respond changing temperature and precipitation. Termites also important decomposers in the tropics but less well studied. An understanding of their climate sensitivities needed estimate change effects on pools. Using data from 133 sites spanning six continents, we found that termite discovery consumption were highly sensitive (with increasing >6.8 times per 10°C...
Summary Plant functional traits have revealed trade‐offs related to life‐history adaptations, geographical distributions, and ecosystem processes. Fine roots are essential in plant resource acquisition play an important role soil carbon cycling. Nonetheless, root trait variation is still poorly quantified rarely the rest of plant. We examined chemical morphological 34 temperate arbuscular mycorrhizal tree species, representing three main angiosperm clades (super‐orders asterid, magnoliid...
Ancient Amazon soils are characterised by low concentrations of soil phosphorus (P). Therefore, it is hypothesised that plants may invest a substantial proportion their resources belowground to adjust P-uptake strategies, including root morphological, physiological (phosphatase enzyme activities) and biotic (arbuscular mycorrhizal (AM) associations) adaptations. Since these strategies energy demanding, we hypothesise trade-offs between morphological traits phosphatase exudation symbiotic...
Soil nutrient availability can strongly affect root traits. In tropical forests, phosphorus (P) is often considered the main limiting for plants. However, support P paradigm limited, and N cations might also control forests functioning. We used a large-scale experiment to determine how factorial addition of nitrogen (N), affected productivity traits related acquisition strategies (morphological traits, phosphatase activity, arbuscular mycorrhizal colonisation contents) in primary rainforest...
It remains unclear how evolutionary and ecological processes have shaped the wide variety of plant life strategies, especially in highly diverse ecosystems like tropical forests. Some evidence suggests that species diversified across a gradient with different tissues converging to optimize resource use environmental gradients. Alternative hypotheses propose following independent selection on tissues, resulting decoupling trait syndromes organs. To shed light subject, we assembled an...
Summary The root economics space (RES) is multidimensional and largely shaped by belowground biotic abiotic influences. However, how root–fungal symbioses edaphic fertility drive this complexity remains unclear. Here, we measured absorptive traits of 112 tree species in temperate subtropical forests China, including linked to functional differences between arbuscular mycorrhizal (AM) ectomycorrhizal (ECM) hosts. Our data, from known species, revealed a ‘fungal‐symbiosis’ dimension...
Summary Tropical forest root characteristics and resource acquisition strategies are underrepresented in vegetation global models, hampering the prediction of forest–climate feedbacks for these carbon‐rich ecosystems. Lowland tropical forests often have globally unique combinations high taxonomic functional biodiversity, rainfall seasonality, strongly weathered infertile soils, giving rise to distinct patterns traits functions compared with higher latitude We provide a roadmap integrating...
We resampled one of the earliest replicated experimental sites used to investigate impacts native tropical tree species on soil properties, examine longer term effects 1‐m depth. The mono‐dominant stands, established in abandoned pasture 1988 at La Selva Biological Station, Costa Rica, contained six species, including exotic, Pinus patula ssp. tecunumanii (Eguiluz & J.P. Perry) Styles, and five species: Pentaclethra macroloba (Willd.) Ktze (N 2 ‐fixing); Hyeronima alchorneoides Allemao;...
Summary Large variation in tree root architecture and morphology has been reported for temperate forest communities. However, it is not clear whether this represents adaptation of species to specific soil properties, alternative resource acquisition strategies among co‐occurring species, or canalized traits without a strong impact on the success individuals different environments. Here, our goal was test these hypotheses quantify how community‐aggregated intraspecific trait variations are...
Recent studies on fine root functional traits proposed a economics hypothesis where adaptations associated with mycorrhizal dependency strongly influence the organization of traits, forming dominant axis trait covariation unique to roots. This conclusion, however, is based tradeoffs few widely studied traits. It unknown how other fit into this mycorrhizal-collaboration gradient. Here, we provide significant extension field ecology by examining secondary compounds coordinate We analyzed...
Abstract Purpose Large parts of the Amazon rainforest grow on weathered soils depleted in phosphorus and rock-derived cations. We tested hypothesis that this ecosystem, fine roots stimulate decomposition nutrient release from leaf litter biochemically by releasing enzymes, exuding labile carbon stimulating microbial decomposers. Methods monitored a Central tropical rainforest, where were either present or excluded, over 188 days added substrates (glucose citric acid) fully factorial design....
