Across the edge: Spatial segregation drives community structure in tri-trophic multilayer networks at a forest-grassland edge. [PDF]
J Anim EcolThis study reveals how forest–grassland edges act as ecological barriers that shape tri‐trophic interaction networks. Using multilayer network theory, it uncovers how species influence and biodiversity patterns emerge across spatial layers, offering novel insights into edge‐driven community assembly and conservation in fire‐prone mosaics.

Islands in the desert for cavity-nesting bees and wasps: Ecology, patterns of diversity, and conservation at oases of Baja California Peninsula. [PDF]
Ecol Evol, 2020 Abundance and richness were higher in oases, about 65% of nest abundance and 50% of species occurred exclusively in the oasis. Bees did not discriminate between oasis and desert habitats to nest and mud‐daubing wasps were highly dependent of oases, thus at least 21 species could be threatened if the oases of BCP disappear in the future.

Molecular Ecology, Volume 32, Issue 23, Page 6449-6460, December 2023., 2023 Abstract Urbanization is affecting arthropod communities worldwide, for example by changing the availability of food resources. However, the strength and direction of a community's response is species‐specific and depends on species' trophic level. Here, we investigated interacting species at different trophic levels in nests of cavity‐nesting bees and

Environmental DNA, Volume 5, Issue 6, Page 1163-1176, November 2023., 2023 We developed a DNA metabarcoding workflow to identify cavity‐nesting Hymenoptera using environmental DNA collected from vacated nest tubes. Despite limited DNA quantity and quality, we detected Hymenoptera at the species level in 57.4% of our samples. Created with BioRender.com.

Nesting biology of Trypoxylon petiolatum Smith, 1858 (Crabronidae), a cavity-nesting solitary wasp new to Europe [PDF]
Journal of Hymenoptera Research, 2022 We report on the discovery of the spider-hunting wasp Trypoxylon petiolatum (Crabronidae) nesting in three localities in the Province of Girona (Catalonia, NE Spain) in 2019 and 2021.

Insect Conservation and Diversity, Volume 16, Issue 5, Page 725-731, September 2023., 2023 Trap nests are a standardised tool so far used for monitoring bees, wasps and their interacting antagonists. With DNA‐barcoding, we now have quantified three‐trophic interaction networks, including antagonists and food resources. Food resources in wasp brood cells revealed so far unknown food species, including crop and forest pests. Construction of up

Insect Conservation and Diversity, Volume 16, Issue 4, Page 468-482, July 2023., 2023 A high quality of biodiversity measures, proximity to forest and to oilseed rape promoted cavity‐nesting host insects. Their natural enemies benefited from proximity to forest and larger measures' area. Cavity‐nesting wasps benefited from proximity to biodiversity measures, to forest and to oilseed rape.

Functional resin use in solitary bees
Ecological Entomology, Volume 47, Issue 2, Page 115-136, April 2022., 2022 Overall, more than 30% of bee species depend on non‐floral resources such as resin, which is used in nesting for nest structures, chemical camouflage, defence, moisture regulation, and its anti‐microbial properties. Resin usage appears to be constrained by environmental and physiological factors and may play a major role in determining the ambient nest

Vertical stratification of selected Hymenoptera in a remnant forest of the Po Plain (Italy, Lombardy) (Hymenoptera: Ampulicidae, Crabronidae, Sphecidae) [PDF]
, 2017 Communities of the canopy of temperate forests are still relatively unexplored. Furthermore, very little is known on how vertical stratification for some insect groups is related to biological strategies.
