SLAM Project - Long Term Ecological Study of the Impacts of Climate Change in the natural forest of Azores: VI - Inventory of Arthropods of Azorean Urban Gardens

Abstract

The data we present are part of the long-term project SLAM (Long Term Ecological Study of the Impacts of Climate Change in the natural forest of Azores) aiming to assess the impact of biodiversity erosion drivers on Azorean native biota, using long-term ecological data. Additionally to SLAM (Sea, Land and Air Malaise) traps, nocturnal Active Aerial Searching and nocturnal Foliage Beating methods were used to sample, between 2017 and 2018, the arthropod biodiversity on two historical urban gardens of Azores, the “Jardim Botânico” of Faial Island and “Jardim Duque da Terceira” of Terceira Island. We provided an inventory of arthropods collected between 2017 and 2018 in two urban gardens of Faial and Terceira Islands (Azores). A total of 8342 specimens were collected, in which 7493 specimens were identified to species/subspecies level (Faial n = 3296; Terceira n = 4197). The identified specimens belong to four classes, 15 orders, 80 families and 159 species and subspecies of arthropods. A total of 84 species and subspecies are considered introduced (n = 2454 specimens), 50 native non-endemic (n = 4444 specimens), eight endemic (n = 217) and 17 have an indeterminate origin (n = 378). This study also revises the arthropod inventory of these Azorean gardens, by adding/updating the taxonomic names of three orders, ten families and 22 species.
