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...
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...
Abstract Photosynthetic capacity and its relationship to leaf nitrogen content are two of the most sensitive parameters terrestrial biosphere models (TBM) whose representation in global‐scale simulations has been severely hampered by a lack systematic analyses using sufficiently broad database. Here, we use data qualitative traits, climate soil subdivide vegetation into functional types (PFT), then assimilate observations carboxylation capacity, V max (723 points), maximum photosynthesis...
The Farquhar et al. model of C3 photosynthesis is frequently used to study the effect global changes on biosphere. Its two main parameters representing photosynthetic capacity, Vcmax and Jmax, have been observed acclimate plant growth temperature for single species, but a general formulation has never derived. Here, we present reanalysis data from 36 species quantify dependence Jmax with focus temperature, i.e. plants' average ambient during preceding month. within each set was described...
Abstract The controls on aboveground community composition and diversity have been extensively studied, but our understanding of the drivers belowground microbial communities is relatively lacking, despite their importance for ecosystem functioning. In this study, we fitted statistical models to explain landscape‐scale variation in soil using data from 180 sites covering a broad range grassland types, climatic conditions England. We found that was explained by abiotic factors like climate,...
Collaboration broadens the “root economics space” ranging from “do-it-yourself” to “outsourcing” mycorrhizal partners.
Summary Accurate representation of photosynthesis in terrestrial biosphere models ( TBM s) is essential for robust projections global change. However, current representations vary markedly between s, contributing uncertainty to carbon fluxes. Here we compared the seven s by examining leaf and canopy level responses photosynthetic CO 2 assimilation A ) key environmental variables: light, temperature, concentration, vapor pressure deficit soil water content. We identified research areas where...
Summary Competitor, stress‐tolerator, ruderal ( CSR ) theory is a prominent plant functional strategy scheme previously applied to local floras. Globally, the wide geographic and phylogenetic coverage of available values leaf area LA ), dry matter content LDMC specific SLA (representing, respectively, interspecific variation in size conservative vs . acquisitive resource economics) promises general application strategies across biomes, including tropical forests hosting large proportion...
Great uncertainty exists in the global exchange of carbon between atmosphere and terrestrial biosphere. An important source this lies dependency photosynthesis on maximum rate carboxylation (V cmax) electron transport (J max). Understanding making accurate prediction C fluxes thus requires characterization these rates their relationship with plant nutrient status over large geographic scales. Plant is indicated by traits: leaf nitrogen (N), phosphorus (P), specific area (SLA). Correlations V...
Abstract. There is a growing consensus that land surface models (LSMs) simulate terrestrial biosphere exchanges of matter and energy must be better constrained with data to quantify address their uncertainties. FLUXNET, an international network sites measure the carbon, water using eddy covariance technique, prime source for model improvement. Here we outline multi-stage process "fusing" (i.e. linking) LSMs FLUXNET generate quantifiable uncertainty. First, describe availability, its random...
Abstract Question Are plant traits more closely correlated with mean annual temperature, or precipitation? Location Global. Methods We quantified the strength of relationships between temperature and precipitation 21 from 447,961 species‐site combinations worldwide. used meta‐analysis to provide an overall answer our question. Results Mean was significantly strongly than precipitation. Conclusions Our study provides support for some assumptions classical vegetation theory, points many...
Leaf dark respiration (Rdark ) is an important yet poorly quantified component of the global carbon cycle. Given this, we analyzed a new database Rdark and associated leaf traits. Data for 899 species were compiled from 100 sites (from Arctic to tropics). Several woody nonwoody plant functional types (PFTs) represented. Mixed-effects models used disentangle sources variation in . Area-based at prevailing average daily growth temperature (T) each site increased only twofold tropics, despite...
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,...
Abstract. Terrestrial carbon (C) cycle models applied for climate projections simulate a strong increase in net primary productivity (NPP) due to elevated atmospheric CO2 concentration during the 21st century. These usually neglect limited availability of nitrogen (N) and phosphorus (P), nutrients that commonly limit plant growth soil turnover. To investigate how projected C sequestration is altered when stoichiometric constraints on cycling are considered, we incorporated P into land...
