Drivers of species knowledge across the tree of life.
Knowledge of biodiversity is unevenly distributed across the Tree of Life. In the long run, such disparity in awareness unbalances our understanding of life on Earth, influencing policy decisions and the allocation of research and conservation funding. We investigated how humans accumulate knowledge of biodiversity by searching for consistent relationships...Mammola, Stefano ; Adamo, Martino ; Antić, Dragan ; Calevo, Jacopo ; Cancellario, Tommaso …
