- Monitoring agroforest plots under the scope of the COMCHA project. 1. Baseline data for the vascular plants and arthropods of "Vale da Fonte Plot" in Pico Island (Azores Archipelago)Publication . Lago, Alexandra; Petrone, Andrea; Costa Miranda Soares, António Onofre; Canelas Boieiro, Mário Rui; Horta Lopes, David; Freitas, Tiago; Lhoumeau, Sébastien Georges André; Wallon, Sophie; Borges, Paulo; Mologni, FabioABSTRACT: Agroforestry is increasingly promoted as a nature-based solution (NbS) capable of reconciling production with biodiversity conservation, particularly in island landscapes, where endemism and fragmentation heighten conservation stakes. We established a permanent agroforest monitoring plot at Vale da Fonte (Pico Island, Azores) to generate baseline data on vascular plants and terrestrial arthropods and to evaluate whether a structurally complex orchard embedded in native coastal forest can support native and endemic biotas and key ecosystem functions. We used a modified COBRA framework integrating complementary active protocols (nocturnal aerial searching, day/night beating and day sweeping), together with pollinators time transects, pan traps and targeted pest traps. We collected 69 standardised samples (5 plant, 64 arthropod) and made the dataset publicly available in Darwin Core format via the GBIF IPT for long-term use.
- 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.
