![]() The records in FunAndes stem from 18 unpublished datasets contributed by different research groups conducting fieldwork in the region. Here, we present the FunAndes database, a compilation of plant functional traits in the tropical Andes (Fig. Synthesizing and harmonizing trait measurements from remote and understudied areas is critical for global and regional data archiving initiatives 21, and for advancing empirical biodiversity research. These information gap limits our understanding of variation in plant trait composition and diversity at regional, continental, and global scales. However, trait information for Andean plants is underrepresented in global plant trait databases. With about 2% of the terrestrial area of the planet, it holds 10% of the species of vascular plants 18, 19, – 20. The tropical Andes is a major hotspot of global biodiversity and endemism. Yet, the geographical coverage of trait measurements still remains limited for highly diverse tropical areas, especially in mountainous regions 15, 16. Global databases of plant functional traits currently feature an unprecedented amount of trait information that supports scientific work on plant functional ecology, including BIEN 14, GIFT 15, and TRY 16, 17. Exploring variation in plant functional traits provides key insights into plant species distribution, community assembly mechanisms, evolutionary strategies, and ecosystem level potential responses to global environmental change 5, 6, 7, 8, 9, 10, 11, 12, 13. estimated with equations from wood anatomyįunctional traits are measurable properties of a plant describing its structure, function or life history strategy that determine species responses to biotic and abiotic environmental conditions across scales of biological complexity, from communities to ecosystems 1, 2, 3, 4.optical analysis of cross sections with specific software.inductively-coupled plasma atomic emission spectroscopy.Stem conduit density (vessels and tracheids).Stem conduit cross-sectional area (vessels and tracheids).Leaf texture (sclerophylly, physical strength, toughness).Leaf potassium (K) content per leaf dry mass.Leaf phosphorus (P) content per leaf dry mass.Leaf nitrogen (N) isotope signature (delta 15 N).Leaf nitrogen (N) content per leaf dry mass.Leaf magnesium (Mg) content per leaf dry mass.Leaf dry mass per leaf fresh mass (leaf dry matter content, LDMC).Leaf carbon (C) isotope signature (delta 13 C).Leaf carbon (C) content per leaf dry mass.Leaf calcium (Ca) content per leaf dry mass.Leaf aluminium (Al) content per leaf dry mass. ![]() Scientific Data volume 9, Article number: 511 ( 2022) FunAndes – A functional trait database of Andean plants
