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.

Are Botanical Biopesticides Safe for Bees (Hymenoptera, Apoidea)?
The recent global decline in insect populations is of particular concern for pollinators. Wild and managed bees (Hymenoptera, Apoidea) are of primary environmental and economic importance because of their role in pollinating cultivated and wild plants, and synthetic pesticides are among the major factors contributing to their decline.

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 ...
