Aim Functional traits of organisms are key to understanding and predicting biodiversity and ecological change, which motivates continuous collection of traits and their integration into global databases. Such trait matrices are inherently sparse, severely limiting their usefulness for further analyses. On the other hand, traits are characterized by the(More)
Earth is home to a remarkable diversity of plant forms and life histories, yet comparatively few essential trait combinations have proved evolutionarily viable in today's terrestrial biosphere. By analysing worldwide variation in six major traits critical to growth, survival and reproduction within the largest sample of vascular plant species ever compiled,(More)
Abbreviations SLA = Specific leaf area; CWM = community-weighted mean; N mass = leaf nitrogen per unit mass; A area = maximum leaf photosynthesis rate per unit area; NE = na€ ıve estimate; BCE = bias-corrected estimate. Abstract Aim: Do plant trait databases represent a biased sample of species, and if so, can that bias be corrected? Ecologists are(More)
