Habitat and forage associations of a naturally colonising insect pollinator, the tree bumblebee Bombus hypnorum.

open access: yesPLoS ONE, 2014
Bumblebees (Bombus species) are major pollinators of commercial crops and wildflowers but factors affecting their abundance, including causes of recent population declines, remain unclear.

The Downward Floral Orientation in Polygonatum cyrtonema Enhances Pollination Efficiency and Reproductive Fitness

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We reveal that the downward floral orientation in Polygonatum cyrtonema functions as a key floral trait, increasing visitation by effective bumble bees and reducing interference from inefficient insects, while also shielding reproductive tissues from rain and solar radiation.

Dragon Fruit (Hylocereus undatus) Pollination in New Zealand: A Preliminary Report on Flower Visitors, Natural Pollen Deposition, and Artificial Pollination

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Dragon fruit (pitaya; Hylocereus undatus) is a promising, new high‐value crop in New Zealand. The large nocturnal flowers open for one night and close early in the morning the following day over a 3‐ to 6‐month long flowering period. In dragon fruit's native range, hawkmoths and bats are key nocturnal pollinators, and honey bees visit flowers during ...

The effects of flower supplementation on pollinators and pollination along an urbanisation gradient

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 654-668, March 2026.
Enhancing urban greenspaces for pollinator communities by planting flower patches is increasingly common, but their efficacy for different groups of insects (bees, hoverflies and moths) is unclear. Our city‐scale experiment demonstrated that the effect of flower patches on pollinators is complex, and direct benefits to specific insects are difficult to

Community‐level effects of Müllerian mimicry on pollinator diversity and functioning

open access: yesFunctional Ecology, Volume 40, Issue 3, Page 599-610, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Müllerian mimicry, a mutualistic interaction in which harmful species evolve similar warning signals, is often accompanied by niche divergence among mimetic species. While these aspects have traditionally been studied in an evolutionary context, their community‐level ...

Proteomic Characterization of the Venom of Five Bombus (Thoracobombus) Species

open access: yesToxins, 2017
Venomous animals use venom, a complex biofluid composed of unique mixtures of proteins and peptides, to act on vital systems of the prey or predator. In bees, venom is solely used for defense against predators.

Think globally, breed locally: Limited genetic impact of management in solitary bees (Osmia bicornis and Osmia cornuta)

open access: yesJournal of Applied Ecology, Volume 63, Issue 3, March 2026.
The data suggest that the release of locally reared Osmia spp. is unlikely to interfere with the genetic structure of wild conspecifics. This contrasts with bumblebees, where the use of non‐local colonies has led to genetic introgression with local conspecific populations.

Fatty Acids from Pool Lipids as Possible Precursors of the Male Marking Pheromone in Bumblebees

open access: yesMolecules, 2014
Triacylglycerols (TGs) stored in the fat bodies of bumblebee males have a species-specific composition. The striking structural similarities between TG fatty acids (FAs) and components of the male marking pheromone in certain species led to the ...

Adaptive Significance of Nickel Hyperaccumulation by Plants

open access: yesEcological Research, Volume 41, Issue 2, March 2026.
Metal hyperaccumulation may enhance plant fitness through multiple, non‐exclusive mechanisms, including elemental defense against herbivores and pathogens, altered pollinator interactions, and increased reproductive performance in metal‐rich soils. Metals may also affect plant–plant interactions via elemental allelopathy and improve stress tolerance ...

Bumblebee assemblages (Hymenoptera, Apidae) of ruderal habitats in the Kola Peninsula, NW Russia

open access: yesFauna Norvegica, 2015
Bumblebee assemblages of ruderal habitats were studied in the Kola Peninsula in 2012. The number of species in the assemblages varies from 7 to 11. Of cryptic species Bombus sensu stricto in the Kola Peninsula only Bombus cryptarum was registered.
