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 ...

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 ...

Year‐round pollinator visitation of ornamental plants in Mediterranean urban parks

Insect Conservation and Diversity, Volume 19, Issue 3, Page 702-715, May 2026.
Pollinators visiting ornamental plants in urban parks remained diverse throughout the year. They were represented by wild bees (42%), honeybees (37%), flies (18%), butterflies (2%) and beetles (1%). Both native and non‐native plants attracted pollinators.

Different Paths, Similar Pressures: Divergent Drivers of Genetic Diversity Despite Convergent Genomic Signatures of Selection in Response to Urban Intensity in Two Oligolectic Bee Species

Molecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Urbanisation is a pervasive form of anthropogenic environmental change and a driver of contemporary evolution. Yet, it remains unclear how demographic processes and environmentally associated genomic variation shape genomic patterns in cities and whether these responses depend on species‐specific ecological traits.

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.

Unveiling the Patterns of Wild Bee‐Plant Interactions on a Large and Mostly Unexplored Mediterranean Island (Sardinia, Italy)

Ecology and Evolution, Volume 16, Issue 4, April 2026.
An extensive survey of wild bee and bee–plant networks in Sardinia (Italy) highlights high species richness and diversity, particularly in mainland agroecosystems. All interaction networks were highly specialized, modular, and not nested, indicating potential ecological vulnerability, though varying across sites and on a temporal scale.

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.

Differential effects of agricultural expansion on wild bee taxonomic and functional diversity

Functional Ecology, Volume 40, Issue 4, Page 878-892, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollinators, especially bees, are in global decline, threatening biodiversity and food security. While intensive agriculture is a primary driver, its impact on bee functional diversity—particularly in the diverse Mediterranean region—remains understudied.

Landscape and local factors influence solitary bee nesting, but reported effects show little consistency across studies

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Collectively, these findings indicate that agri‐environment schemes aiming to support solitary bees should integrate the provision of nesting resources with proximity to floral resources. The heterogeneity among studies highlights the need for solitary bee conservation measures to be tailored to local conditions and to the local fauna.
