Intergrative taxonomy and biogegraphy of ants in the genus Anoplolepis (Hymenoptera: Formicidae) in Southern Africa
Taxonomy has played an important role in biodiversity assessments. It provides an understanding of biodiversity components, data that are essential for making decisions on conservation and sustainable use and is also a foundation for phylogenetic studies. Although this field of study has played an …
