Morphological and Ecological Traits Explain Variation in Desiccation Tolerance Among Bees

Ecology and Evolution, Volume 16, Issue 9, September 2026.
We assessed the desiccation tolerance in 22 bee species from the Greek island of Lesbos. Larger bees lost water more slowly and survived longer, while survival declined with increasing water loss rate and water content at mortality. Morphological and ecological traits shaped physiological responses, highlighting trait‐based mechanisms underlying ...

How Bees Respond Differently to Field Margins of Shrubby and Herbaceous Plants in Intensive Agricultural Crops of the Mediterranean Area

Insects, 2019
(1) Intensive agriculture has a high impact on pollinating insects, and conservation strategies targeting agricultural landscapes may greatly contribute to their maintenance.

eDNA Analysis for Native Cavity‐Nesting Bee Ecology: A Comparison of Data From Brood Cells Contents and Larval DNA

Environmental DNA, Volume 8, Issue 5, September‐October 2026.
Artificial bee homes become eDNA reservoirs of insect, plant, fungal, and bacterial taxa providing a non‐invasive way to assess the ecology of wild bee larvae. ABSTRACT While the colonial honeybee is widely recognized by the public as a pollinator, thousands of native bees play an important but often under‐recognized role.

Bee diversity and floral resources along a disturbance gradient in Kaya Muhaka Forest and surrounding farmlands of coastal Kenya

Journal of Pollination Ecology, 2017
Bees provide important pollination services that maintain native plant populations and ecosystem resilience, which is critical to the conservation of the rich and endemic biodiversity of Kaya forests along the Kenyan Coast.

Uma espécie nova de Anthidianum Michener e notas taxonômicas (Hymenoptera, Megachilidae): (Hymenoptera, Megachilidae) [PDF]

Revista Brasileira de Zoologia, 2001
Anthidianum andicola sp. n. (from Argentina, Tilcara), is described; a description of the male of Chrisanthidium nigritum Urban, 1997 is presented and Anthidianum bizonatum (Friese, 1925) is considered as junior synonym of Anthidianum subpetiolatum (Schrottky, 1910).

Structural Colour in Bees (Hymenoptera: Anthophila) Is Linked to Climate and Latitude

Global Ecology and Biogeography, Volume 35, Issue 9, September 2026.
ABSTRACT Aim Environmental drivers frequently predict global patterns of colour diversity, but whether such patterns depend on the underlying colour mechanisms—pigments or microscopic structures—has scarcely been considered. Structural colour may have different functional properties that result in different associations with environmental variables ...

Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges

Insect Conservation and Diversity, Volume 19, Issue 5, Page 1114-1123, September 2026.
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 ...

A preliminary study of the cleptoparasitic bees of the genus Coelioxys (Hymenoptera: Megachilidae) in northern Iran, with six new records

Journal of Crop Protection, 2013
A survey on the megachilid bees (Hymenoptera: Megachilidae) fauna of northern Iran, between 2010 and 2011, led to the identification of eleven species of the genus Coelioxys Latreille belonging to subgenera Allocoelioxys (6 species), Boreocoelioxys (2 ...

A cytochrome P450 insecticide detoxification mechanism is not conserved across the Megachilidae family of bees

Evolutionary Applications
Recent work has demonstrated that many bee species have specific cytochrome P450 enzymes (P450s) that can efficiently detoxify certain insecticides. The presence of these P450s, belonging or closely related to the CYP9Q subfamily (CYP9Q‐related), is ...
