Floral Color and Family Drive Contrasting Plant–Pollinator Responses to Nutrient Enrichment

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
Floral taxonomic family and color mediated how plant–pollinator reactions respond to nutrient enrichment. Nitrogen enrichment increased yellow and purple Asteraceae flowers and decreased pink, blue, and green flowers in Geraniaceae, Fabaceae, and Iridaceae. These shifts in floral colors and traits altered pollinator composition.

Periacineta mexicana n. sp. (Ciliophora, Suctoria, Discophryida), Epizoic on Mexican Backswimmers of the Genus Buenoa (Insecta, Hemiptera, Notonectidae) [PDF]

open access: yes, 2010
A new species of suctorian in the genus Periacineta, epibiotic on aquatic bugs (Hemiptera, Heteroptera, Nepomorpha), is described on the basis of morphological characteristics of the cell body, lorica, tentacular placement, and stalk, and its 18S rRNA ...

Examining Honeybee (Apis mellifera) Dominance Patterns Within Urban Bee Communities Worldwide

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
We examine if and to what degree honeybees are dominant in urban bee communities worldwide. We found honeybees to be the most abundant organisms and highly dominant in most of the studies, although the dominance degree was quite variable between studies. Our results provide new evidence to contribute to the debate on urban beekeeping and reconciliation

Wolbachiainfections in bees (Anthophila) and possible implications for DNA barcoding

open access: yesSystematics and Biodiversity, 2011
The widespread intracellular bacterium Wolbachia is transmitted exclusively maternally and alters the reproduction of its hosts by different mechanisms. Thereby, inheritance patterns of mitochondrial genomes are modified, possibly confining interpretations of mitochondrial sequence data.

Heterospecific Hymenoptera found inside the nests of Bombus impatiens (Hymenoptera: Apidae). [PDF]

open access: yes, 2018
The nests of social Hymenoptera are particularly attractive to species engaging in resource robbing due to their concentration of resources. Here, the identity of heterospecific intruders in Bombus impatiens nests are described, with a particular focus ...

Plant Communities in the Americas Are Highly Bee Dependent Regardless of Biome or Local Bee Diversity

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 8, August 2025.
ABSTRACT Aim All bees depend on angiosperms for survival, while many angiosperms depend on bees for reproduction. However, bee and flowering plant species richness do not peak in the same geographical regions of the world, suggesting that the flora in regions where bees are not as diverse, such as the tropics, may be relatively less bee‐dependent.

Megachile sculpturalis, the Giant Resin Bee, overcomes the blossom structure of Sunn Hemp (Crotalaria juncea) that impedes pollination [PDF]

open access: yes, 2016
Bee species that are effective pollinators of sunn hemp (Crotalaria juncea L.: Fabaceae: Crotalarieae) are few in number because of the large size and papilionaceous structure of the plant’s blossom.

The Buzz of Inconsistency: Pollinator Potential vs. Research Effort

open access: yesJournal of Applied Entomology, Volume 149, Issue 7, Page 1050-1058, August 2025.
ABSTRACT Pollinator insects are essential for the functioning of terrestrial ecosystems and play a critical role in ensuring food security; thus, studies on this topic provide significant benefits for human society. Pollination involves diverse taxa that can vary depending on the specific environment.

A new species of Ptiloglossa from Mexico, with new records of Ptiloglossa cyaniventris from Panama and Costa Rica (Hymenoptera: Colletidae) [PDF]

open access: yes, 2014
A new bee species of the genus Ptiloglossa Smith (Colletidae: Diphaglossinae: Caupolicanini) is described and figured from Jalisco, Mexico, while new records are provided for Ptiloglossa cyaniventris Friese from Panama and a single locality in Costa Rica.
