- Monitoring of potential invasive arthropod species in Azores Islands (Corvo, Flores, Faial, Pico, Terceira, São Miguel and Santa Maria): The PRIBES ProjectPublication . Leite, Abrão; Canelas Boieiro, Mário Rui; Costa Miranda Soares, António Onofre; Ros Prieto, Alejandra; Costa, Ricardo; Pozsgai, Gabor; Oyarzabal da Silva, Guilherme; Coelho Teixeira, Mário; Calado, Hugo Renato; Lago, Alexandra; Vounatsi, Martha; Gabriel, Rosalina; Wallon, Sophie; Crespo, Luís Carlos; Gil de Gómez, Juan; Henriques Alves Ferreira, Maria Teresa; Lhoumeau, Sébastien Georges André; Borges, P.A.V.; Ruzzier, EnricoABSTRACT: Arthropods provide essential ecosystem services, yet multiple lines of evidence indicate widespread declines driven by habitat loss (degradation, fragmentation and reduction), biological invasions and climate change. Oceanic islands are particularly vulnerable to invasive alien species because of their isolation, small area and sensitivity to novel predators, competitors and pathogens. In the Azores, historical land-use change has greatly reduced native forest cover, while long-term monitoring indicates that introduced arthropod diversity is increasing even where total richness appears stable. However, ruderal coastal habitats (i.e. transitional, frequently disturbed environments often dominated by opportunistic exotic plants) remain comparatively under-sampled and may function as early “gateways” for new arthropod introductions. The PRIBES project intends to contribute to "The Regional Strategy for the Management of Terrestrial and Freshwater Exotic and Invasive Species in the Azores" (PRIBES-LIFE-IP- Estratégia regional para o controlo e prevenção de espécies exóticas invasoras - no âmbito do projeto LIFE IP AZORES NATURA, LIFE17 IPE/PT/000010). The PRIBES project addresses this gap by surveying arthropod assemblages associated with vascular plants in disturbed coastal ruderal habitats across multiple Azorean islands (Corvo, Flores, Faial, Pico, Terceira, São Miguel and Santa Maria) using a standardised time-based plant beating protocol, enabling comparisons of richness and colonisation status (endemic, native or exotic) amongst islands and vegetation contexts.
- Vertical distribution of arthropod assemblages in native and exotic forests of Terceira Island (Azores, Portugal)Publication . Lhoumeau, Sébastien Georges André; Leite, Abrão; Parmentier, Laurine Marie; Massard, Clémence; Vounatsi, Martha; Lucie, Georgery; Borges, P.A.V.; Soares, AntónioABSTRACT: In the summer of 2024, a study was conducted on Terceira Island in the Azores Archipelago, Portugal, aiming to characterise the vertical diversity and spatial distribution patterns of arthropods within native and exotic forest ecosystems. This study forms part of a broader research initiative designed to investigate how alterations in habitat structure influence the complexity and stability of arthropod food webs in Azorean forest habitats. By systematically sampling arthropods across multiple vertical strata —from forest floor to canopy the study aimed to generate detailed insights into the ecological dynamics governing biodiversity patterns and species interactions. Results from this monitoring will contribute significantly to understanding the ecological impacts of forest composition and management strategies, ultimately providing information for conservation planning and habitat restoration efforts aimed at preserving arthropod diversity and ecological resilience in island ecosystems.
