- Arthropod diversity in two Historic Gardens in the Azores, PortugalPublication . Arteaga, Alba; Malumbres-Olarte, Jagoba; Gabriel, Rosalina; Ros-Prieto, A.; Casimiro, Pedro; Fuentes-Sánchez, Ana; Albergaria, Isabel Soares de; Borges, Paulo A. V.The aim of our study was to characterise and compare the richness and composition of endemic, native (non-endemic) and introduced arthropod assemblages of two Azorean Historic Gardens with contrasting plant species composition. We hypothesised that Faial Botanic Garden would hold higher arthropod diversity and abundance of native and endemic arthropod species due to its larger native plant community. Species were collected using several arthropod standardised techniques between April 2017 and June 2018. We used the alpha diversity metrics (Hill series) and the partitioning of total beta diversity (βtotal) into its replacement (βrepl) and richness (βrich) components, to analyse the adult and total arthropod community. The orders Araneae, Coleoptera and Hemiptera were also studied separately. Our results show that the number of exotic arthropod species exceeds the number of native and/or the endemic species in both gardens, but the arthropod community of Faial Botanic Garden exhibited a higher density of endemic and native species. Despite some minor exceptions, the geographic origins of plant communities largely influenced the arthropod species sampled in each garden. This study improves our knowledge about urban arthropod diversity in the Azores and shows how well-designed urban garden management and planning contribute to the conservation of native and endemic Azorean species.
- New records of moths (Insecta, Lepidoptera) from urban gardens on Terceira Island with new data on recently introduced species to the AzoresPublication . Pérez Santa-Rita, Jose V.; Ros-Prieto, A.; Vieira, Virgílio; Karsholt, Ole; Gabriel, Rosalina; Borges, Paulo A. V.The urban Duque da Terceira Garden, in the main town of Angra do Heroísmo (Terceira, Azores), was investigated to describe the species composition of moths (Insecta, Lepidoptera). Moths were sampled with two methods: SLAM traps (between April and September 2017) and light trapping (two sessions in the summer of 2017). A total of 42 taxa were sampled with the addition of 19 new records for Duque da Terceira Garden, five of which were also new records for Terceira Island. The five species recorded as new for Terceira were subjected to an exhaustive taxonomic analysis. In addition, we revised the colonization status of some species. Our results show that urban gardens may help the establishment of exotic species and that it is necessary to monitor and control how these species established in urban environments.
- Seasonal dynamics of arthropods in the humid native forests of Terceira Island (Azores)Publication . Borges, Paulo A. V.; Pimentel, Reinaldo M. S.; Carvalho, Rui; Nunes, Rui; Wallon, Sophie; Ros-Prieto, A.This work aims to provide a first detailed description of the results obtained in a seasonal abundance study of arthropods in the native pristine humid forest from Terceira Island (Azores). Ten sites were sampled during four years with SLAM (Sea, Land, and Air Malaise) traps targeting several arthropod taxa with good dispersal abilities as well as epigean species crawling into the trap. Samples were taken every three months in nine sites between 2012 and 2016 and monthly in one of the sites between 2014 and 2015. A total of 147 arthropod species and morphospecies were sampled mostly belonging to Hemiptera, Araneae and Coleoptera. Four endemic species, the tree lace-hopper Cixius azoterceirae, the capsid bug Pinalitus oromii, the bristletail Trigoniophthalmus borgesi and a morphospecies of Aleyrodidae accounted for 50% of all adult specimens. Most species peak in abundance in summer, but monthly data allowed the identification of other seasonal patterns.
- Standardised inventories of spiders (Arachnida, Araneae) on touristic trails of the native forests of the Azores (Portugal)Publication . Carvalho, Rui; Cardoso, Pedro; Gil, Artur José Freire; Ferreira, Maria Teresa; Ramos, Cândida; Lamelas-López, Lucas; Pereira, Fernando; Malumbres-Olarte, Jagoba; Ros-Prieto, A.; Boieiro, Mário; Borges, Paulo A. V.In the Azores, as in many other temperate, semi-tropical and tropical islands, historical patterns of habitat loss have typically resulted in lowland clearance, meaning that the last remnants of the pre-human pristine forest that covered the major parts of oceanic islands are in the mountain areas (Gaspar et al. 2011). The communities of these mountain forests are of critical importance for the protection of current island biodiversity since they are home to many Azorean endemic species (Borges et al. 2017, Borges et al. 2018, Malumbres-Olarte et al. 2019) and provide a variety of ecosystem services (e.g. water storage, erosion control, pollination, pest-control, food supply, recreation and tourism), contributing to the local economy and welfare (Fernandez-Palacios et al. 2017). The recent increase in recreational tourist activities in native habitats of the Azores (SREA 2018) raises concerns about the use of trails being a threat to the already imperilled native forest biodiversity. Hiking trails in particular have been found to be promoting the spread of invasive plants (Barros and Pickering 2014), which may cause adverse cascading effects on arthropods. The spider communities of the Azores are exceptionally well known due to ongoing inventorying and monitoring projects carried out since 1999 (Borges et al. 2016, Emerson et al. 2017, Malumbres-Olarte et al. 2019). The protocol used in NETBIOME ISLANDBIODIV and in this project is part of a long term monitoring proposal for oceanic islands (Borges et al. 2018).
