- Dung beetles of Azorean cattle-grazed pasturelands - data of the DUNGPOOL projectPublication . Duenas-Rojas, Almudena; Cuesta, Eva; Parmentier, Laurine Marie; Leite, Abrão; Borges, P.A.V.; Coelho dos Santos, Ana Margarida; Soares, AntónioABSTRACT: The data we present are part of the project DUNGPOOL, which aims to evaluate the effects of the species pool, community assembly processes and increasing temperatures on the local diversity and ecosystem functions performed by dung beetles in island and mainland cattle-grazed pasturelands. By combining replicated field experiments on the Iberian Peninsula with parallel work on three mid-Atlantic islands (Pico, Faial and Terceira, Azores), the project exploits the natural contrast between a species-rich mainland pool and the species-poor, largely exotic island pools, to test explicit biodiversity–ecosystem-function (BEF) hypotheses across spatial scales. From June to July 2024, dung beetles were sampled in 84 locations of the three islands of the Azores Archipelago (Portugal), using 306 pitfall traps baited with fresh cow dung.
- Seasonal variation of dung-associated arthropods in cattle pastures of Terceira Island (Azores): a year-round, event-based datasetPublication . Wallon, Sophie; Leite, Abrão; Duenas-Rojas, Almudena; Cuesta, Eva; Coelho dos Santos, Ana Margarida; Lhoumeau, Sébastien Georges André; Borges, P.A.V.; Soares, AntónioDung-associated arthropods, particularly dung beetles (Scarabaeidae), together with rove beetles (Staphylinidae) and water scavenger beetles (Hydrophilidae), support key ecosystem functions in cattle-grazed landscapes, including dung removal, nutrient cycling, soil aeration and pest suppression. Their activity is strongly seasonal in temperate systems, driven by temperature and moisture and can be further reshaped by pasture management (e.g. changes in grazing regimes and dung availability). Oceanic islands add an important perspective because species pools are typically smaller and often dominated by introduced taxa, potentially altering phenology and dominance patterns across the year. However, year-round, standardised, event-based datasets for dung-associated arthropod assemblages remain scarce for oceanic islands, limiting robust comparisons amongst guilds, sites and management regimes and reducing our ability to benchmark seasonal windows of activity under climate variability and land-use change.
