Taxonomic and functional diversity of urban bees of the world

Conservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Forest edges buffer effects of agricultural management on bee–plant interaction networks

Ecological Entomology, EarlyView.
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

Ecological Entomology, EarlyView.
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 ...

Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges

Insect Conservation and Diversity, EarlyView.
Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...

NEW RECORDS OF PANURGINE BEES (HYMENOPTERA, ANDRENIDAE, PANURGINAE) FROM IRAQ

Bulletin of the Iraq Natural History Museum
In the current study, the panurgine bee Camptopoeum Spinola, 1843 is represented as a single species Camptopoeum frontale (Fabricius, 1804) (Family Andrenidae), which is reported as a new record for the Iraqi Hymenoptera checklist.

Against the odds: Nesting specialization and foraging ecology provide insights into climate change responses in a mountain bee

Insect Conservation and Diversity, EarlyView.
A unique high‐elevation Exoneura bee defies typical elevation‐driven declines in bee activity, nesting exclusively in dead branches of snow gums near the alpine tree line. Nesting and foraging are tightly linked to snow gum presence, with most activity occurring within 30 m of these trees. Biophysical modelling indicates the bee's thermally constrained

Uso de recursos florales por Andrenidae, Colletidae y Megachilidae (Hymenoptera: Apoidea) en el Chaco Serrano de Córdoba

Revista Chilena de Entomología
Se determinó la diversidad de Andrenidae, Colletidae y Megachilidae en una sección del Bosque Serrano de Córdoba, Argentina (31°10’ S, 64°20’ O) y se analizó el aprovechamiento por parte de ellas de los recursos florales en esta zona.

Two new species of Crawfordia Pierce from South America, (Strepsiptera: Stylopidae)

Memorias do Instituto Oswaldo Cruz, 1989
Several stylopized specimens were found among the Hymenoptera collection of the Instituto Oswaldo Cruz (Rio de Janeiro, Brazil). A paper by Kogan & Oliveira (1966) described the parasites of Polybia represented among those specimens.

Mapping wild bee diversity and flower use for an effective conservation of the Doñana biodiversity hotspot

Insect Conservation and Diversity, EarlyView.
We compiled the first checklist of wild bees in Doñana Protected Area, documenting 385 species, including three vulnerable and one endangered species listed in the Red List. Bee species exhibit diverse floral preferences, highlighting the need to incorporate plant–pollinator interactions and the role of plants in conservation and management strategies ...

AutoPollS: A tool for automated monitoring of pollinators using deep learning

Methods in Ecology and Evolution, Volume 17, Issue 6, Page 1743-1753, June 2026.
Abstract Deep learning and computer vision hold enormous potential for automated monitoring of biodiversity, including pollinators and other insects. Efficient, scalable monitoring of insect pollinators is crucial given pollinators' role in supporting biodiversity and agricultural productivity amidst declining pollinator populations.
