 Mosaic is an open-access trait database that integrates data from three existing databases, Kamada, Kampadre, and Padrino, to provide a comprehensive resource for researchers studying the relationship between demographics and traits. The database contains over 1,400 species and provides information on 300 species including biomass, height, growth determination, regeneration, sexual dimorphism, mating system, hermaphrodism, sequential hermaphrodism, dispersal capacity, type of dispersal, mode of dispersal, dispersal classes, volency, and aquatic habitat dependency. Additionally, it includes species-level phylogeny and population-specific climate data. By integrating these datasets, Mosaic allows researchers to better understand the relationship between demographics and traits, as well as identify emerging challenges associated with standardizing databases and demographic measures.
