Filtered Join (Advanced Queries)
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.
