Resolving the Azorean knot: a response to Carine & Schaefer (2010)
Triantis, Kostas A.; Hortal, Joaquín; Amorim, Isabel R.; Cardoso, Pedro; Santos, Ana M. C.; Gabriel, Rosalina; Borges, Paulo A. V.Copyright © 2012 Blackwell Publishing Ltd. ; Carine & Schaefer (Journal of Biogeography, 2010, 37, 77–89) suggest that the lack of past climate oscillations in the Azores may have contributed to the low plant endemism in this archipelago compared to that of the Canary Islands, a pattern they term the Azorean diversity enigma. Here we challenge their hypothesis, and discuss how the particular characteristics of...

Patterns of colonization and species distribution for Azorean arthropods: evolu...
Borges, Paulo A. V.; Gaspar, Clara; Santos, Ana M. C.; Ribeiro, Sérvio P.; Cardoso, Pedro; Triantis, Kostas A.; Amorim, Isabel R.Proceedings of the Symposium "Darwin's Mistake and what we are doing to correct it". Ponta Delgada, 19-22 September, 2009. ; Com base em estudos ecológicos e biogeográficos realizados nos Açores (um arquipélago remoto composto por nove ilhas vulcânicas) durante muitos anos de uma forma continuada, apresentamos um conjunto de questões. O grupo alvo são os artrópodes e o principal habitat é a Laurissilva, a flor...
Macroecological patterns of species distribution, composition and richness of t...
Borges, Paulo A. V.; Cardoso, Pedro; Cunha, Regina Tristão da; Gabriel, Rosalina; Gonçalves, Vitor; Hortal, Joaquín; Martins, António M. de FriasWe investigate the macroecological patterns of the terrestrial biota of the Azorean archipelago, namely the species-range size distributions, the distance decay of similarity, and the island species–area relationship (ISAR). We use the most recent up-to-date checklists to describe the diversity at the island level for nine groups (Lichens, Fungi, Diatoms, Bryophytes, Vascular Plants, Nematodes, Molluscs, Arthro...
Adapting the IUCN red listing criteria for invertebrates
Cardoso, Pedro; Borges, Paulo A. V.; Triantis, Kostas A.; Ferrández, Miguel A.; Martín, José L.Copyright © 2011 Elsevier Ltd. All rights reserved. ; The IUCN Red List is the most useful list of species that are at risk for extinction worldwide, as it relies on a number of objective criteria. Nevertheless, there is a taxonomic bias that excludes species with small body sizes, narrow distribution ranges and low dispersal abilities, which constitute the vast majority of the planet’s biota, particularly loc...
The Macaronesian province: patterns of species richness and endemism of arthropods
Triantis, Kostas A.; Borges, Paulo A. V.; Hortal, Joaquín; Whittaker, Robert J."[…]. The Macaronesian arthropod fauna displays a number of characteristics typical of oceanic islands, including a high degree of endemism, ranging from 19% for the Azores (Borges et al., 2005a), to 28% for Madeira (Borges et al., 2008a), 30% for Cape Verde (Arechavaleta etal., 2005) and 45% for the Canary Islands (Izquierdo et al., 2004; see Table I). The preponderance of endemic species has made the Macarone...
Drivers of diversity in Macaronesian spiders and the role of species extinctions
Cardoso, Pedro; Arnedo, Miquel A.; Triantis, Kostas A.; Borges, Paulo A. V.Copyright © 2010 Blackwell Publishing. ; AIM To identify the biogeographical factors underlying spider species richness in the Macaronesian region and assess the importance of species extinctions in shaping the current diversity. LOCATION The European archipelagos of Macaronesia with an emphasis on the Azores and Canary Islands.
Are species-area relationships from entire archipelagos congruent with those of...
Santos, Ana C.; Whittaker, Robert J.; Triantis, Kostas A.; Borges, Paulo A. V.; Jones, Owen R.; Quicke, Donald L. J.; Hortal, JoaquínCopyright © 2010 Blackwell Publishing Ltd. ; AIM To establish the extent to which archipelagos follow the same species–area relationship as their constituent islands and to explore the factors that may explain departures from the relationship. LOCATION Thirty-eight archipelagos distributed worldwide. METHODS We used ninety-seven published datasets to create island species–area relationships (ISARs) using the A...
Extinction debt on oceanic islands
Triantis, Kostas A.; Borges, Paulo A. V.; Ladle, Richard J.; Hortal, Joaquín; Cardoso, Pedro; Gaspar, Clara; Dinis, Francisco; Mendonça, EnésimaCopyright © 2010 The Authors. Journal compilation © 2010 Ecography. ; Habitat destruction is the leading cause of species extinctions. However, there is typically a time-lag between the reduction in habitat area and the eventual disappearance of the remnant populations. These “surviving but ultimately doomed” species represent an extinction debt. Calculating the magnitude of such future extinction events has b...
Measurements of area and the (island) species-area relationship: new directions...
Triantis, Kostas A.; Nogués-Bravo, David; Hortal, Joaquín; Borges, Paulo A. V.; Adsersen, Henning; Fernández-Palacios, José María; Araújo, Miguel B.Copyright © 2008 The Authors. Journal compilation. ; Copyright © 2008 Oikos. ; The species-area relationship is one of the strongest empirical generalizations in geographical ecology, yet controversy persists about some important questions concerning its causality and application. Here, using more accurate measures of island surface size for five different island systems, we show that increasing the accuracy ...
