Native, alien, cosmopolitan, or cryptogenic? A framework for clarifying the origin status of rotifers

Among small organisms, it is often difficult to distinguish native from alien species because we cannot easily determine where they originate. They are often labelled cosmopolitan or cryptogenic, euphemisms that indicate that we are uncertain of their origin. This lack of information obscures our un...
