However, the new study finds that both record types are flawed, and the degree to which they are riddled with coverage gaps and biases depends on the kind of dataset. Most records either come from physical specimens in a museum or digital field observations, but both are useful for detecting shifts in the number and abundance of species in an area. ![]() ![]() In the race to document the species on Earth before they go extinct, researchers and citizen scientists have assembled billions of records. There are biases and gaps in both natural history collections and in biodiversity apps and digital tools, research finds. ![]()
