A comparison of bryophyte diversity in the Macaronesian Islands: island versus ...
González-Mancebo, Juana M.; Gabriel, Rosalina; Otto, Rüdiger; Sim-Sim, Manuela; Luís, Leena Margarida; Sérgio, Cecília; Garzón-Machado, VíctorIn this paper, we present a comparison of richness patterns and floristic similarity for bryophytes in the five most important altitudinal habitat types in the Macaronesian islands. We evaluate the importance of different factors discussed in the literature in predicting species diversity applying the traditional island approach and within the framework of the new habitat approach, including area, isolation, cl...
Azorean Bryophytes: a preliminary review of rarity patterns
Gabriel, Rosalina; Homem, Nídia; Couto, Adalberto Borges; Aranda, Silvia C.; Borges, Paulo A. V.Proceedings of the Symposium "Darwin's Mistake and what we are doing to correct it". Ponta Delgada, 19-22 September, 2009. ; Os briófitos podem ser tão raros e estar tão ameaçados como os demais organismos do planeta, apesar de o seu pequeno tamanho, cores discretas e difícil identificação no campo poderem mascarar o seu verdadeiro estatuto de conservação. De facto, é reconhecido que cerca de um quarto de todo...
Assessing the completeness of bryophyte inventories: an oceanic island as a cas...
Aranda, Silvia C.; Gabriel, Rosalina; Borges, Paulo A. V.; Lobo, Jorge M.Copyright © Springer Science+Business Media B.V. 2010. ; How useful, complete or unbiased are comprehensive databases in order to provide reliable estimations of diversity? Using compiled data from bryophytes in Terceira Island (Azores), we specifically aim (1) to describe the register of species over time, (2) to assess the inventory completeness, i.e., the ratio between the observed and the maximum expected ...
A spatial scale assessment of habitat effects on arthropod communities of an oc...
Cardoso, Pedro; Aranda, Silvia C.; Lobo, Jorge M.; Dinis, Francisco; Gaspar, Clara; Borges, Paulo A. V.Copyright © 2009 Elsevier Masson SAS. All rights reserved. ; Most habitats in the Azores have undergone substantial land-use changes and anthropogenic disturbance during the last six centuries. In this study we assessed how the richness, abundance and composition of arthropod communities change with: (1) habitat type and (2) the surrounding land-use at different spatial scales. The research was conducted in Te...
