In defence of the entity of Macaronesia as a biogeographical region

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 on the terminology and purpose of regionalism, we recover the origin...

Contribution to the flora of the Selvagens archipelago (Portugal) (I)

Plant specimens obtained by the authors from several expeditions to the Selvagens Islands (2004-2021), complemented by the study of herbarium specimens, led to the identification of several new species records for the Selvagens archipelago, namely the taxa currently considered as Canary Islands endemics Trisetaria lapalmae and Polycarpaea divaricata. Other new taxa records for the Selvagens Islands include Conv...

No presente artigo apresentamos uma nova subaliança Lavandulo luisieri-Cistetum albidi, constituída por um conjunto de comunidades vegetais arbustivas (camefíticas e nanofanerofíticas) características de solos descarbonatados e submetidos a erosão, derivados de calcários (leptossolos, luvissolos crómicos e cambissolos). Tratam-se de comunidades vegetais que ocorrem no ocidente da Península Ibérica, nos territór...

The Scrubland of limestine-derived decarbonated soils of the Western Iberian Pe...

In the present article, the proposal of a new suballiance, Lavandulo luisieri-Cistenion albidi, is presented, constituted by chamaephytic and nanophanerophytic communities in eroded decarbonated soils derived from limestones (leptosols, chromicluvisols and cambisols) in the dry to lower hyperhumid, thermo-mesomediterranean bioclimatic levels. It is distributed throughout the western Iberian Peninsula in the Coa...
