The journal content would have no preference with regard to taxonomic group.

A number of species in this taxonomic group are endangered.

Such common features across a taxonomic group are called synapomorphies.

They are not a taxonomic group but share a common habitat.

In addition, more than 1,800 plant species from diverse taxonomic groups can be observed.

They do not form a taxonomic group, but rather a functional or agronomic one.
