Synonymy of Orthomus susanae Serrano & Borges, 2009 with Orthomus annae (Donaba...

Serrano, Artur R. M.; Aguiar, Carlos A. S.; Boieiro, Mário; Borges, Paulo A. V.; Rego, Carla; Amorim, Isabel R.; Ribeiro, Sérvio P.

Copyright © 2012 Magnolia Press. ; [...]. Some time after the publication of their paper in Zootaxa, the authors found out that another Madeiran Orthomus species had been described one month earlier (Donabauer 2008). Taking in consideration the morphological characteristics of the specimens described in both papers and the coincidence of the type localities no doubts remained regarding the synonymy between the...


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...


Canopy habitat area effect on the arthropod species densities in the Azores: po...

Ribeiro, Sérvio P.; Borges, Paulo A. V.

"[…]. We performed a PIAR examining how plant cover area and plant crown structure influence the densities of arthropods in the canopies of one specific island, comparing various distinct natural reserves. Species densities were measured for two functional insect herbivore guilds (sap-sucking and leaf-chewing insects) and the most common predatory assembly in this system (spiders) in three different ways: i) th...


Extinction debt on oceanic islands

Triantis, Kostas A.; Borges, Paulo A. V.; Ladle, Richard J.; Hortal, Joaquín; Cardoso, Pedro; Gaspar, Clara; Dinis, Francisco; Mendonça, Enésima

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...


Canopy insect herbivores in the Azorean Laurisilva forests: key host plant spec...

Ribeiro, Sérvio P.; Borges, Paulo A. V.; Gaspar, Clara; Melo, Catarina; Serrano, Artur R. M.; Amaral, João; Aguiar, Carlos; André, Genage

Copyright © ECOGRAPHY 2005. ; This article explores patterns of insect herbivore distribution in the canopy of the Laurisilva forests on seven islands in the Azores archipelago. To our knowledge, this is one of the first extensive studied of this type in tree or shrub canopies of oceanic island ecosystems. One of the most frequently debated characteristics of such ecosystems is the likely prevalence of vague, ...


Ranking protected areas in the Azores using standardised sampling of soil epige...

Borges, Paulo A. V.; Aguiar, Carlos; Amaral, João; Amorim, Isabel R.; André, Genage; Arraiol, Anabela; Baz, A.; Dinis, Francisco; Enghoff, H.

Copyright © Springer 2005. ; Nineteen areas in seven of the nine Azorean islands were evaluated for species diversity and rarity based on soil epigean arthropods. Fifteen out of the 19 study areas are managed as Natural Forest Reserves and the remaining four were included due to their importance as indigenous forest cover. Four of the 19 areas are not included in the European Conservation network, NATURA 2000....

Ecology and evolution of the arborescent Erica azorica Hochst (Ericaceae)

Ribeiro, Sérvio P.; Borges, Paulo A. V.; Gaspar, Clara

Copyright © 2003 Universidade dos Açores. ; O objectivo do presente estudo consistiu em avaliar o impacto da herbivoria por insectos na arquitectura da urze Erica azorica Hochst, planta endémica da Laurisilva dos Açores. Erica azorica é uma planta com porte arbustivo e pioneira que consegue persistir nas florestas maduras de Laurisilva, onde pode atingir porte arbóreo tornando-se emergente no copado. Testa-se ...


Relação entre o número de espécies e o número de táxones de alto nível para a f...

Borges, Paulo A. V.; Aguiar, Carlos; André, Genage; Enghoff, H.; Gaspar, Clara; Melo, Catarina; Quartau, José A.; Ribeiro, Sérvio P.

Nesta contribuição pretendemos avaliar a aplicação dos modelos RESTAN, "Relação entre o número de Espécies e o número de Táxones de Alto Nível", à fauna de artrópodes de vários habitats das ilhas dos Açores. Utilizámos várias bases de dados recentemente obtidas baseadas em amostragens estandardizadas de artrópodes epígeos do solo em florestas de áreas protegidas, artrópodes fitófagos e predadores de pastagens s...
