There is growing recognition that classifying terrestrial plant species on the basis of their function (into 'functional types') rather than higher taxonomic identity, a promising way forward for tackling important ecological questions at scale ecosystems, landscapes or biomes. These include those vegetation responses to and effects on, environmental changes (e.g. in climate, atmospheric chemistry, land use other disturbances). also consensus about shortlist traits should underlie such...
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. This line research been among most fruitful avenues...
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...
Humans are modifying both the identities and numbers of species in ecosystems, but impacts such changes on ecosystem processes controversial. Plant diversity, functional composition were experimentally varied grassland plots. Each factor by itself had significant effects many processes, diversity principal factors explaining plant productivity, percent nitrogen, total light penetration. Thus, habitat modifications management practices that change likely to have large processes.
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...
• Global-scale quantification of relationships between plant traits gives insight into the evolution world's vegetation, and is crucial for parameterizing vegetation–climate models. A database was compiled, comprising data hundreds to thousands species core 'leaf economics' leaf lifespan, mass per area, photosynthetic capacity, dark respiration, nitrogen phosphorus concentrations, as well potassium, N-use efficiency (PNUE), N : P ratio. While mean trait values differed functional types,...
Despite striking differences in climate, soils, and evolutionary history among diverse biomes ranging from tropical temperate forests to alpine tundra desert, we found similar interspecific relationships leaf structure function plant growth all biomes. Our results thus demonstrate convergent evolution global generality functioning, despite the enormous diversity of species For 280 two data sets, that potential carbon gain (photosynthesis) loss (respiration) increase proportion with...
Plant diversity and niche complementarity had progressively stronger effects on ecosystem functioning during a 7-year experiment, with 16-species plots attaining 2.7 times greater biomass than monocultures. Diversity were neither transients nor explained solely by few productive or unviable species. Rather, many higher-diversity outperformed the best monoculture. These results help resolve debate over biodiversity functioning, show at higher expected levels, demonstrate, for these...
A global data set including 5,087 observations of leaf nitrogen (N) and phosphorus (P) for 1,280 plant species at 452 sites associated mean climate indices demonstrates broad biogeographic patterns. In general, N P decline the N/P ratio increases toward equator as average temperature growing season length increase. These patterns are similar five dominant groups, coniferous trees four angiosperm groups (grasses, herbs, shrubs, trees). results support hypotheses that ( i ) increase from...
Abstract Despite the importance of microbial communities for ecosystem services and human welfare, relationship between diversity multiple functions (that is, multifunctionality) at global scale has yet to be evaluated. Here we use two independent, large-scale databases with contrasting geographic coverage (from 78 drylands from 179 locations across Scotland, respectively), report that soil positively relates multifunctionality in terrestrial ecosystems. The direct positive effects were...
Variation in leaf life—span has long been considered of ecological significance.Despite this, quantitative evaluation the relationships between and other plant ecosystem characteristics rare. In this paper we ask whether is related to leaf, plant, stand traits species from diverse ecosystems biomes. We also examine interaction their relation productivity patterns. Among all species, both mass— (A m a s ) area—based r e maximum net photosynthesis decreased with increasing life—span, but...
Variation in plant functional traits results from evolutionary and environmental drivers that operate at a variety of different scales, which makes it challenge to differentiate among them. In this article we describe patterns trait variation correlations within habitats relation several trade‐off axes. We then ask whether such reflect natural selection can be considered strategies. so doing highlight evidence demonstrates (1) across resource gradients (light, water, nutrients, temperature)...
Convergence in interspecific leaf trait relationships across diverse taxonomic groups and biomes would have important evolutionary ecological implications. Such convergence has been hypothesized to result from trade-offs that limit the combination of plant traits for any species. Here we address this issue by testing biome differences slope intercept among traits: longevity, net photosynthetic capacity (Amax), diffusive conductance (Gs), specific area (SLA), nitrogen (N) status, more than...
The biodiversity-productivity relationship (BPR) is foundational to our understanding of the global extinction crisis and its impacts on ecosystem functioning. Understanding BPR critical for accurate valuation effective conservation biodiversity. Using ground-sourced data from 777,126 permanent plots, spanning 44 countries most terrestrial biomes, we reveal a globally consistent positive concave-down BPR, showing that continued biodiversity loss would result in an accelerating decline forest...
ABSTRACT Aim This first global quantification of the relationship between leaf traits and soil nutrient fertility reflects trade‐off growth conservation. The power soils versus climate in predicting trait values is assessed bivariate multivariate analyses compared with distribution forms (as a discrete classification vegetation) across gradients climate. Location All continents except for Antarctica. Methods Data on specific area (SLA), N concentration (LNC), P (LPC) N:P were collected 474...
