Improved phylogenies and the accumulation of broad comparative data sets have opened the way for phylogenetic analyses to trace trait evolution in major groups of organisms. We arrayed seed mass data for 12,987 species on the seed plant phylogeny and show the history of seed size from the emergence of the angiosperms through to the present day. The largest(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)
Question: Are plant traits more closely correlated with mean annual temperature , or with mean annual precipitation? Methods: We quantified the strength of the relationships between temperature and precipitation and 21 plant traits from 447,961 species-site combinations worldwide. We used meta-analysis to provide an overall answer to our question. Results:(More)
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)
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)
