Ecotaxonomy Anton Potapov / Dorothee Sandmann / Stefan Scheu Ecotaxonomy (, is an open web platform, that allows traits, taxa, individuals and samples to be linked within research projects. Any morphological or ecological traits can be customized inside the system and attached either to taxa, individuals, or environmental samples. The system is flexible to include any group of organisms. The taxonomic system of Ecotaxonomy is based on the Global Biodiversity Information Facility (, but may be complemented by morphospecies, pictures, literature and other parameters. As public output, the system provides interactive identification keys and web catalogs of traits and taxa. Multiple morphological and ecological traits Multiple groups of organisms (focused on Arthropoda)

Bacterial and archaeal phenotypic trait database Joshua Madin A synthesis of phenotypic and quantitative genomic traits is provided for bacteria and archaea, in the form of a scripted, reproducible workflow that standardizes and merges 26 sources. The resulting unified dataset covers 14 phenotypic traits, 5 quantitative genomic traits, and 4 environmental characteristics for approximately 170,000 strain-level and 15,000 species-aggregated records. It spans all habitats including soils, marine and fresh waters and sediments, host-associated and thermal. Trait data can find use in clarifying major dimensions of ecological strategy variation across species. They can also be used in conjunction with species and abundance sampling to characterize trait mixtures in communities and responses of traits along environmental gradients. 14 phenotypic traits, 5 quantitative genomic traits, and 4 environmental characteristics Approximately 170,000 strains and 15,000 species
