The native bee fauna of the Palouse Prairie (Hymenoptera: Apoidea) [PDF]
While synoptic collections provide data on the range and general composition of the North American bee fauna, bee communities associated with specific habitats are largely uncharacterized.

Wild bee functional groups consist of species that are grouped together based on their similarity in multiple nesting and foraging traits. These functional groups have their own specific association with suitable habitats and urban or agricultural landscapes.

On the roles of colour and scent in a specialized floral mimicry system [PDF]
Background and Aims Sexually deceptive orchids achieve cross-pollination by mimicking the mating signals of female insects, generally hymenopterans. This pollination mechanism is often highly specific as it is based primarily on the mimicry of mating ...

A subgeneric classification is proposed for Triepeolus—the second‐largest genus of cleptoparasitic apid bees in the world—and its sister genus Epeolus, with support from a newly presented dated phylogeny. Phylogenomic analysis based on ultraconserved elements revealed strong support for the monophyly of Triepeolus, which diverged from Epeolus sometime ...

The restoration of ecological interactions: plant-pollinator networks on ancient and restored heathlands [PDF]
1. Attempts to restore damaged ecosystems usually emphasize structural aspects of biodiversity, such as species richness and abundance. An alternative is to emphasize functional aspects, such as patterns of interaction between species.

Abstract Pollinator declines pose a significant threat to ecosystem services, making effective monitoring methods critical for conservation efforts. Current research on pollination interactions remains constrained by traditional methods such as direct observations, which have limited spatial and temporal coverage and are inherently biased toward ...

Cuticular Hydrocarbons as Sex Pheromone of the Bee Colletes cunicularius and the Key to its Mimicry by the Sexually Deceptive Orchid, Ophrys exaltata [PDF]
Male Colletes cunicularius bees pollinate the orchid, Ophrys exaltata, after being sexually deceived by the orchid's odor-mimicry of the female bee's sex pheromone. We detected biologically active volatiles of C. cunicularius by using gas chromatographic-

Mixed effects of urbanization on pollination services among four native plant species
We tested urbanization and fragmentation effects on pollination services using four native phytometer species that were deployed across 10 community gardens located in suburban and densely urbanized areas Landscape context generally did not influence pollination; however, for one of four phytometers (Lobelia siphilitica, pictured above) urban cover ...

Wege der Mikroevolution und Artbildung bei Bienen (Apoidea, Hymenoptera): Populationsgenetische und empirische Aspekte [PDF]
Bees are haplodiploid organisms: haploid males develop from unfertilized eggs, diploid females from fertilized eggs. Under haplodiploidy, deleterious mutations are effectively purged by purifying selection on haploid males.

High‐purity single‐photon emission at telecom O‐band is demonstrated from droplet‐epitaxy InAs quantum dots embedded in a GaAs/AlGaAs microcavity. Strain engineering via an InAlAs buffer enables broadband telecom emission with high purity, short lifetimes, and enhanced extraction.
