Towards systematic conservation planning in the Azores

Several field methodologies, analytical measures and theoretical patterns have been explored for conservation planning for arthropods in native forests of the Azores archipelago. Here, the outcomes are assembled to make recommendations on practical strategies to assess arthropod diversity and to select and manage protected native forests in the Azores. Suggestions are made on how to apply similar plans for cons...

Patterns of colonization and species distribution for Azorean arthropods: evolu...

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...

Patterns of alpha and beta diversity of epigean arthropods at contrasting land-...

"[…]. To study the effect of land-use change in biological communities it is necessary to understand how are the different components of diversity distributed in space. Diversity has long been separated into different components according to the phenomena that interest ecologists (Whittaker, 1960, 1972): i) local species richness, i.e., alpha (community) diversity that measures the species richness of a local a...

Selection of priority areas for arthropod conservation in the Azores archipelago

Copyright © Springer Science+Business Media B.V. 2010. ; The largest standardised database available to date for arthropods in native forests of the Azores archipelago was used to determine the minimum optimal set of native forest fragments needed to accomplish four different targets of species occurrence (presence-absence) and abundance (20, 50 and 80%) using different groups of arthropods and all data combin...

Arthropods as surrogates of diversity at different spatial scales

Copyright © 2010 Elsevier Ltd. All rights reserved. ; This study evaluates the effectiveness of taxonomic, colonization and trophic groups of arthropods from native forests of the Azores archipelago as surrogates of the diversity of other arthropod groups and of the remaining arthropods. Consistency in the performance of surrogates was tested across three spatial scales and using two measures of diversity. Pit...

Extinction debt on oceanic islands

Copyright © 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...

Vulcões e Mistérios

"Os vulcões, com todos os fenómenos a eles associados, sempre causaram um enorme fascínio ao ser humano. As fumarolas, as nascentes termais, os sismos, e as explosões ocasionais acompanhadas por lavas escorrentes, eram vistas como manifestações de deuses que habitam o interior da Terra ou como penalizações de índole espiritual. Quando na maior parte do mundo este tipo de manifestações é desconhecido, nos Açores...

A spatial scale assessment of habitat effects on arthropod communities of an oc...

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...
