“…For spider surveys in agricultural landscapes, the efficiency of different sampling methods is often debated (Lang 2000;Sanders and Entling 2011). While commonly used, pitfall traps only capture the activity-density rather than the actual population density of the trapped species (Bali et al 2019). Suction sampling may therefore give better estimates of true densities, but is largely restricted to vegetation-dwelling arthropods (Sanders and Entling 2011).…”

Farmland biodiversity: wildflower-sown islands within arable fields and grassy field margins both promote spider diversity

Agricultural intensification and the concomitant landscape homogenization is leading to a worldwide decline in farmland biodiversity. Non-crop habitats in agroecosystems may counteract the loss of arthropods such as spiders and thus contribute to sustainable agriculture. However, the effectiveness of field margins and set-aside wildflower-sown patches in maintaining spider diversity is not well understood. Here, we investigated the effects of three different non-crop habitats, namely field margins, set-aside wildflower-sown patches under power poles (‘power pole islands’), and grassland fallows on spider diversity as compared to wheat fields in an agricultural landscape in western Germany. Using pitfall trapping and suction sampling, we show that species richness and overall conservation value were higher in non-crop habitats than in wheat fields. Interestingly, field margins and power pole islands differed from long-term grassland fallows only in conservation value, which was significantly higher in grassland fallows. Species assemblages differed considerably between grassland fallows, field margins and power pole islands, and wheat fields, documenting the added value of using different conservation strategies. Implications for insect conservation Small-scale non-crop habitats adjacent to wheat fields were surprisingly effective in promoting spider diversity in an agricultural landscape, with field margins and power pole islands being equally effective. To maximize overall diversity in agricultural landscapes, we propose a combination of larger long-term fallows and smaller non-crop habitats such as field margins or set-aside wildflower-sown patches.

“…Lors d'un inventaire arachnologique classique, la méthode la plus efficace (temps passé rapporté au nombre d'espèces collectées) est l'aspirateur thermique (Brook et al, 2008 ;Bali et al, 2019). Dans le cadre de La Planète Revisitée, la méthode la plus efficace a été la chasse à vue, avec 183 espèces, ce qui, au vu du nombre de participants et de leur expérience, n'est pas une surprise.…”

Contribution of the mission Our Planet Reviewed to the knowledge of spiders: 33 species new to Corsica, including two species new for the French fauna (Arachnida, Araneae). As part of Our Planet Reviewed in Corsica 2019-2021 project, 364 spider taxa were inventoried. This mission made it possible to update the list of species recorded on the island: 33 species of spiders are added to the Corsican araneofauna, which goes from 687 to 721 taxa; two species are also new to the fauna of France, Orchestina longipes Dalmas, 1922 (Oonopidae) and Pseudeuophrys perdifumo van Helsdingen, 2015 (Salticidae). A comparison of sampling techniques is proposed, and for some new taxa comments on ecology or taxonomy are added. Finally, the main groups of species by type of habitat studied and a zoom on the “heritage” species are presented, in view of the recently published National Red List.
