You are curious about what other kinds of animals get caught in the Sherman traps used to census the rodents. Write a query that returns a list of the genus, species, and taxa (from the species table) for non-rodent individuals that are caught on the Control plots. Non-rodents are indicated in the taxa column of the species table. You are only interested in which species are captured, so make this list unique (only one line for each species). Save this query as non_rodents_on_controls.
