Meaningful ecological studies on insect communities require sampling protocols that take into consideration temporal fluctuations in abundance and species composition. Bees with their specific requirements for nutrition and nesting are good indicators of

Diversity and Evolution of pogo and Tc1/mariner Transposons in the Apoidea Genomes
Bees (Apoidea), the largest and most crucial radiation of pollinators, play a vital role in the ecosystem balance. Transposons are widely distributed in nature and are important drivers of species diversity.

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Forest edges buffer effects of agricultural management on bee–plant interaction networks
Agricultural management effects: Organic and conventional crop margins host similar bee and plant species, but network structure differs: organic farms exhibit higher interaction diversity, conventional farms higher connectance. Role of forest edges: Native forest edges stabilize bee–plant networks by providing continuous floral resources and suitable ...

Influence of elevation, climate, snowmelt and floral abundance on body size of solitary bees
We measured body size in bee species from a 10‐year specimen collection from Colorado sub‐alpine meadows (2450–3450 m) and tested effects of elevation and annual snowmelt, climate and floral abundance. 2 out of 4 bee species collected across a broad elevation range showed a decline in body size with higher elevations; the other two showed no effect ...

Understanding dietary preferences and prey selection is pivotal for interpreting the ecology and conservation needs of threatened species. We investigated the diet composition and prey selection of the Red‐backed Shrike Lanius collurio in a montane grassland of the central Italian Apennines, with special regard to sex‐related differences and the ...
