Towards systematic conservation planning in the Azores
Gaspar, Clara; Borges, Paulo A. V.; Gaston, Kevin J.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...
Selection of priority areas for arthropod conservation in the Azores archipelago
Gaspar, Clara; Borges, Paulo A. V.; Gaston, Kevin J.; Cardoso, PedroCopyright © 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
Gaspar, Clara; Gaston, Kevin J.; Borges, Paulo A. V.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...
Abundance, spatial variance and occupancy: arthropod species distribution in th...
Gaston, Kevin J.; Borges, Paulo A. V.; He, FangLiang; Gaspar, ClaraCopyright © 2006 British Ecological Society. ; 1. The positive abundance-occupancy and abundance-variance relationships are two of the most widely documented patterns in population and community ecology. 2. Recently, a general model has been proposed linking the mean abundance, the spatial variance in abundance, and the occupancy of species. A striking feature of this model is that it consists explicitly of th...
