- Monitoring grassland’s arthropods in a in situ climate change experimentation (Terceira, Azores, Portugal)Publication . Wallon, Sophie; Borges, Paulo A. V.; Elias, Rui B.The data presented are part of the project PASTURCLIM (Impact of climate change on pasture’s productivity and nutritional composition in the Azores). The project aims to assess consequences of climate change (in this case, increasing temperature) on the grass production and quality for cattle forage. The project also aims to assess changes in the arthropod’s community associated to the grassland. An in situ experimentation was set up using Open Top Chambers (OTC’s), in order to simulate an increasing of temperature (average of +1.5⁰C) on grassland. In this paper, we present data relative to the arthropods collection. Overall, we collected 41,351 specimens belonging to four classes, 15 orders, 60 families and 171 morphospecies (including 34 taxa identified only at order, family of genus level). Therefore, for only 137 taxa we have a scientific name associated (n = 38918).
- Sampling of Azores seabirds with camera-traps - Year 2019Publication . Lamelas-López, Lucas; Borges, Paulo A. V.The Azores holds the largest population of Cory´s shearwater Calonectris borealis (Cory, 1881) in the world. One of the major threats of this species in the Azores is the predation by invasive mammals, which were introduced from European colonization of the islands. The present publication provides a data set from a camera-trapping survey performed in colonies of Cory’s shearwater. The sampling was conducted between 8 April and 23 October of 2019, covering the entire breeding season, in three colonies of the Terceira Island (Azores). A total of 32 nests were sampled using motion-triggered cameras. This publication aims to provide information about the ecological patterns of the Cory Shearwater, and to identify potential nest predators. This publication includes a total of 6972 records across 15 species (9 species of birds, 5 of mammals and 1 of reptiles), which 5414 records are of Cory’s shearwater, 478 of potential mammal predators and 1080 of another vertebrate species. Information about biology of the species is also provided, as species circadian behaviour and habitat description.

- Trechus terrabravensis (Green Status assessment)Publication . Borges, Paulo A. V.JUSTIFICATION: Trechus terrabravensis has a Species Recovery Score of 83% (Slightly Depleted). The species is endemic to Ilha Terceira. While much forest has been cleared on the island, and protected areas established in response, the species is a habitat specialist restricted to inaccessible areas and it is unclear how much habitat has been lost to human development; therefore, the Conservation Legacy is Indeterminate. The species has a High Conservation Dependence; without continued management of invasive plants, the species' score is expected to decrease to 25% over the next 10 years. However, continued removal of invasive plants and creation of corridors is expected to benefit the species in future, with maximum expected recovery to 92% achievable within the next 10 years, giving the species a Low Conservation Gain and Recovery Potential.
- Marine and coastal ecosystems and climate change : dataset from a public awareness surveyPublication . Fonseca, Catarina; Wood, Louisa; Andriamahefazafy, Mialy; Casal, Gema; Chaigneau, Tomas; Cornet, Cindy C.; Degia, Anna; Failler, Pierre; Ferraro, Gianluca; Furlan, Elisa; Hawkins, Julie P.; de Juan, Silvia; Krause, Torsten; McCarthy, Timothy; Pérez, Géraldine; Roberts, Callum M.; Tregarot, Ewan; O’Leary, Bethan C.The dataset is the result of an self-administered online survey on public perceptions about climate change, the value of marine and coastal ecosystems, human impacts on them and their management. The survey was released in four languages, English, French, Spanish and Italian ('survey' folder). Potential respondents were provided with a participant information form, also available in four languages ('participant information form' folder). The final dataset comprises a total of 709 respondents. The dataset contains mostly numerical coding, except text entries in 9 columns. Version 2 of this dataset presents all responses in English. The corresponding codebook provides the questions and coding information.
- Diversity of Lepidoptera recorded in a forest nursery of Nordeste county on São Miguel Island (Azores)Publication . Vieira, Virgilio; Oliveira, Luísa; Soares, António O.; Borges, Paulo A. V.; Borges, Isabel; Tavares, JoãoThe diversity of moth species (Insecta, Lepidoptera) recorded in the forest nursery of Nordeste county on São Miguel island (Azores) is given. Adults were sampled between March and December 2019 using three methods: (i) light trap to caught Noctuidae species, (ii) open-sided delta trap baited with a synthetic female sex pheromone lure to attract Epiphyas postvittana males and (iii) entomological net to identify microlepidopteran moths. A total of 10160 adults belonging to 33 lepidopteran species were recorded and listed by families, including: Argyresthiidae 1 (3%), Crambidae 4 (12%), Erebidae 1 (3%), Geometridae 5 (15%), Noctuidae 18 (55%), Sphingidae 1 (3%), Tineidae 1 (3%), and Tortricidae 2 (6%). The families Noctuidae, Geometridae and Crambidae were the most diverse. Those with the highest abundance of adults was the Noctuidae family followed by the Crambidae, Trotricidae and Tineidae. The number of caught adults was consistently higher during spring and summer, decreasing sharply in late fall. For 14 species caught in the light trap the adult sex ratio was favorable to females, except for Xestia c-nigrum which was favorable to males. An analysis of the colonization status, feeding and primary hosts of these endemic, native or exotic moth species suggests that plants reared in forest nurseries, being attacked by such insects, facilitates our understanding of the diversity of lepidopterans that establish in Laurel Forest environments and to what extent there is a need to monitor and control them mainly with biological control agents.
- Eden Arthropod Azores DatabasePublication . Marcelino, Jose; Borges, Paulo A. V.; Borges, Isabel; Soares, António O.This study intended to contribute to the current international directives concerning biodiversity, aiming to document and safeguard biological resources of the globe. Our objective was to present the most widely distributed and diverse taxa recorded during the sampling phase of the EDEN project (2008-2014), specifically all arthropod fauna, at all strata, within eight representative habitats of five islands of the Azores archipelago (Santa Maria, São Miguel, Terceira, Flores and Pico)
- Standardised sampling of lepidopterans (Lepidoptera) in Serra da Estrela (Portugal) - 2013 and 2014. v1.2Publication . Boieiro, Mário; Antunes, Sandra; Figueiredo, Hugo; Soares, Albano; Lopes, Ana; Monteiro, Eva; Pereira, Patrícia Garcia; Rego, Carla; Conde, José; Borges, Paulo A. V.; Serrano, Artur R. M.Mountain ecosystems are crucial for biodiversity conservation since they host high biodiversity. This study reports novel information on lepidopteran species diversity, distribution and abundance from Serra da Estrela Natural Park (Portugal). Seventy two lepidopteran species were sampled in this protected area, including the first findings of Apatura ilia (Denis & Schiffermüller, 1775) and Vanessa virginiensis (Drury, 1773). New populations of Euphydrias aurinia (Rottemburg, 1775), a protected species under the Habitats Directive, was found in this Natural Park and novel distribution and ecological data was collected for most species, including several rare species [e.g., Coenonympha glycerion iphioides Staudinger, 1870, Cyaniris semiargus (Rottemburg, 1775)]. All data were collected using standardised sampling allowing its use as baseline for environmental changes long-term monitoring of Serra da Estrela mountain biodiversity.
- Long-term monitoring of Azorean forest arthropodsPublication . Borges, Paulo A. V.; Lhoumeau, SébastienSince 2012 we are conducting in Azorean Islands (Portugal) native and exotic forests a long-term monitoring study named SLAM - Long Term Ecological Study of the Impacts of Climate Change in the natural forest of Azores. This long-term monitoring study is monitoring arthropods (Arthropoda), aiming to understand the impact of biodiversity erosion drivers in Azorean native forests arthropod distribution, abundance and diversity. The current dataset represents arthropods that were recorded using a total of 42 passive SLAM traps (Sea, Land and Air Malaise) deployed inside native and exotic forest fragments in seven Azorean Islands (Flores, Faial, Pico, Graciosa, Terceira São Miguel and Santa Maria). This manuscript is the fifth data-paper contribution based on data from this long-term project. We provide data of terrestrial arthropods belonging to Arachnida (excluding Acari), Diplopoda, Chilopoda and Insecta classes (excluding Collembola, Diptera, Hymenoptera and Lepidoptera) from seven Azorean Islands during the 2012-2021 period. Data from spiders (Araneae) from the Pico and Terceira Islands is not included in this publication since this data was already published elsewhere (Costa and Borges 2021; Lhoumeau et al. 2022). We collected a total of 176007 specimens, of which 168565 (95.7%) were identified at species or subspecies level. Among these identified specimens, 106 350 (62%) were adults. For Araneae and some Hemiptera species, juveniles are also included in the data presented in this paper, since the low diversity in the Azores allows a relatively precise species-level identification of this life-stage. We recorded a total of 316 species and subspecies, belonging to 25 orders, 106 families and 260 genera. The ten most abundant species are composed mostly of endemic or native non-endemic species and only one exotic species (Ommatoiulus moreleti (Lucas, 1860)). They include 107 330 individuals (60%) of all sampled specimens and can be considered as the dominant species in the Azorean native forests for the target studied taxa. The Hemiptera order was the most abundant taxa, with 90 127 (50,4%) specimens. The Coleoptera order was the most diverse taxa with 30 (28,3%) family sampled. We registered 72 new species records (two for Flores, eight for Faial, 24 for Graciosa, 23 for Pico, eight for Terceira, three for São Miguel and four for Santa-Maria). None of them are new for the Azores archipelago. Most of the new records are introduced species, however abundance of such species is still low on the studied islands. This publication contributes to increase the baseline information for future long-term comparisons of the arthropods of the studied sites and the knowledge of the arthropod fauna of the native forests of the Azores, in terms of species abundance, distribution and diversity throughout seasons and years.
