In defence of the entity of Macaronesia as a biogeographical region
Biological Reviews, Volume 99, Issue 6, Page 2060-2081, December 2024.ABSTRACT Since its coinage ca. 1850 AD by Philip Barker Webb, the biogeographical region of Macaronesia, consisting of the North Atlantic volcanic archipelagos of the Azores, Madeira with the tiny Selvagens, the Canaries and Cabo Verde, and for some authors different continental coastal strips, has been under dispute. Herein, after a brief introduction
