The historical biogeography and conservation value of taxonomic distinctness: The case of ferns flora of the Gibraltar Arc

Abstract

The pteridofloras of nine locations in the Gibraltar Arc were analyzed using a taxonomic distinctness index. We found that the index could be a proxy of historical biogeography of the pteridofloras from this area. Moreover, the value of the taxonomic distinctness index of the different locations showed relevant relationships with certain geographic variables. Finally, we hypothesize about the value of the information derived from taxonomic distinctness index for conservation of the pteridoflora in the Gibraltar Arc.

Analysis of taxonomic distinctness and priority conservation areas as a basis for heritage enhancement of floristic diversity: the case of the ‘hotspot’ of the islands of Numidia (North-eastern Algeria)

“…This article aims to provide quantitative values for decision-making about land use and the conservation of ecosystems. Thus, the objective of our study was to test a method based on taxonomic distinctness (TD;Salvo Tierra et al, 2021) in order to quantify the heritage value of a territory and establish the most appropriate measures for conserving it in accordance with SDG 15, as well as to identify PCA following the methodology implemented by Vane-Wright (1991). This method has been proposed by Salvo Tierra & García Verdugo (1988), Murguía &Rojas (2001) andSalvo Tierra et al (2020), obtaining results with conservation applicability.…”
