Dados Sobre o Projeto
In the summer of 2024, a monitoring study was conducted in the Azorean Islands of Terceira (Portugal) to assess arthropod diversity and distribution in native and exotic forests. This initiative forms part of a project that aims to evaluate the impact of habitat structure change on arthropod food web complexity in Azorean forests. In particular, the study seeks to assess how changes in arthropod biodiversity are influenced by the structural complexity of forestsThe current dataset comprises terrestrial arthropods collected using SLAM (Sea, Land, and Air Malaise) traps across diverse forest strata and Pitfall traps.

| Financiamento | Sebastien Lhoumeau was funded by the project « The impact of habitat structure change on arthropod food web complexity in Azorean forests” (M3.1.a/F/012/2022) » Additional Funding come for : Portal da Biodiversidade dos Açores (2022-2023) - PO Azores Project - M1.1.A/INFRAEST CIENT/001/2022 (2022); FCT-UIDB/00329/2020-2024 (Thematic Line 1 – integrated ecological assessment of environmental change on biodiversity) (2019-2022); Science and Technology Foundation (FCT) - MACRISK-Trait-based prediction of extinction risk and invasiveness for Northern Macaronesian arthropods (FCT-PTDC/BIA-CBI/0625/2021) (2022) |
| Descrição da Área de Estudo | The Azores are an isolated archipelago situated at 38°43′49″N, 27°19′10″W in the mid-Atlantic Ocean. The archipelago comprises nine volcanic islands, which are spread over 500 km in a W/NW–E/SE direction. During this project, the island of Terceira (the third biggest) was surveyed. Ten sampling plots were selected in areas of native vegetation, predominantly dominated by endemic species such as Juniperus brevifolia, Erica azorica, Laurus azorica, and Ilex azorica, with some indications of invasive species like Pittosporum undulatum and Hedychium gardnerianum. Ten additional plots were situated in secondary forests, predominantly characterised by Pittosporum undulatum and Hedychium gardnerianum, yet exhibiting indications of endemic and native ferns such as Dryopteris azorica and Diplazium caudatum |
| Descrição do Design | The experimental design entailed a 90-day sampling period, spanning from June to September 2024, across all the twenty sites. The sampling method employed was SLAM traps, with three traps deployed at each site. These traps were positioned at varying heights within the forest, specifically at 0%, 50%, and 75% of the maximum canopy height. Additionally, 14 pitfall traps were utilised at each site for a duration of 14 days, commencing in July and concluding in August 2024 |

Métodos de Amostragem
Passive flight interception SLAM traps (Sea, Land and Air Malaise trap) were used to sample the plots, with three traps being setup at each plot at different height within the forest. Traps are 110 x 110 x 110 cm. In this type of trap, the trapped arthropods crawl up the mesh and then fall inside the sampling recipient (Borges et al. 2017). Each one is filled with propylene glycol (pure 1,2-PROPANODIOL) to kill the captured arthropods and conserve the sample between collections, enabling also the preservation of DNA for future genetic analysis. Although this protocol was developed to sample flying arthropods, by working as an extension of the tree, non-flying species such as spiders can also crawl into the trap (Borges et al. 2017), enhancing the range of groups that can be sampled by this technique. Because of this, previous studies have used these traps to analyse diversity and abundance changes in the arthropod communities in Azores pristine forest sites (Matthews et al. 2019, Borges et al. 2020, Lhoumeau and Borges 2023). The traps samples were collected after 3 months in the studied sites. We completed the sampling by using 14 passive pitfall traps randomly distributed within the plots to sample the epigean fauna. Traps have a 5 opening diameter and filled with ethylene-glycol. Pitfall traps were collected after two weeks (14 nights) of continuous operation
| Área de Estudo | A total of twenty 20m x 20m plots were sampled in one island from the archipelago (Terceira). Ten of these plots were set constitute some of the most well-preserved wet forests in these islands, having small human disturbance (Borges et al. 2017).The native forest is dominated by endemic vegetation such as Juniperus brevifolia, Erica azorica, Laurus azorica and Ilex azorica (see Borges et al. 2017 for more details). Ten other plots are in secondary forests, with dominated by exotic and invasive trees |

| Controle de Qualidade | All sorted specimens were identified by a taxonomical expert |
Descrição dos passos do método:
- Taxonomy follows the last clecklist of Azorean arthropods (Borges et al., 2022)
- The data has been published as a Darwin Core Archive (DwC-A), which is a standardised format for sharing biodiversity data as a set of one or more data tables. The core data table (events) contains 338 records, and one data table extension also exists (occurrence), with 1688 records. The extension supplies extra information about the core record.

| Introduction | This comprehensive dataset serves as a significant augmentation of the existing baseline knowledge concerning the diversity of Azorean arthropods, thereby facilitating the formulation of future long-term ecological comparisons. The dataset offers invaluable insights into the vertical distribution of species abundance within both native and secondary forests of the Azores. |
| Getting Started | The dataset encompasses arthropods from the Arachnida (excluding Acari), Diplopoda, Chilopoda, and Insecta classes (excluding Collembola, Diptera, Hymenoptera, and Lepidoptera A total of 32,797 specimens were collected, with 18,372 (56%) identified at the species or subspecies level, including 12,745 adults, and 5,627 juveniles for taxa such as Araneae and Hemiptera due to the availability of reliable identification methods. The resulting dataset encompasses 150 species and 11 subspecies, distributed across six classes, 21 orders, 81 families, and 148 genera. |
