Intermediate fragmentation surrounding vineyards favours the Coleoptera community within the crop

Abstract

1. Insects of the order Coleoptera play an essential role in agricultural sustainability by supporting many ecosystem services (such as biological control, nutrient cycling or pollination). In agroecosystems, the Coleoptera community may be influenced by the surrounding landscape, which can provide living resources, like food or shelter, during different seasons, originating spillover movements between different environments.2. The present study aimed to evaluate the response of the Coleoptera community to the landscape surrounding vineyards at different buffers. For that, Coleoptera were sampled in six wine protected designation of origin (PDO) regions of Portugal (35 vineyards), and landscape configuration and composition metrics were calculated at buffers of 500, 750, 1000, 1500 and 2000 m radii around the vineyards. 3. In total, 2954 Coleoptera individuals belonging to 36 families were collected. The most abundant families were Chrysomelidae, Coccinellidae and Latridiidae. Results indicated that intermediate habitat fragmentation levels, particularly in semi-natural areas and vineyards, favoured Coleoptera biodiversity in vine-producing regions. Moreover, the range of activity of Coleoptera seems to be larger than 1000 m. 4. This work constitutes an important contribution to understanding the response of the Coleoptera community to the landscape context in vineyards in Portugal and contributes to the theoretical framework about the influence of habitat fragmentation on biodiversity.

Individual energetics scale up to community coexistence: Movement, metabolism and biodiversity dynamics in fragmented landscapes

“…for biodiversity is similar to suggestions made byLoke et al (2019),Szangolies et al (2022) andTaranto et al (2023). The field studies ofLoke et al (2019) andTaranto et al (2023) speculated that this was due to factors such as dispersal limitation, local negative density dependence, niche opportunities, and edge effects. However, a comprehensive mechanistic understanding is still lacking.…”

Area and configuration of both semi‐natural habitats and vineyards influence arthropods in South African and central European agricultural landscapes

“…In addition, the effects of landscape configurational heterogeneity on biodiversity have not been explicitly assessed. Indeed, configurational heterogeneity has rarely been assessed in viticultural landscapes in other parts of the world (but see Taranto et al (2023)).…”
