Examples

## the plant class Bangiophyceae
gbif_downstream(key = 198, downto="genus")
gbif_downstream(key = 198, downto="genus", intermediate=TRUE)

# get families downstream from the superfamily Acridoidea
gbif_downstream(key = 1878, "family")
## here, intermediate leads to the same result as the target
gbif_downstream(key = 1878, "family", intermediate=TRUE)

# get species downstream from the genus Ursus
gbif_downstream(key = 2433406, "species")

# get tribes down from the family Apidae
gbif_downstream(key = 1334757, downto="species")
gbif_downstream(key = 1334757, downto="species", intermediate=TRUE)
