BumbleBEEP: A Sensor System for Bumblebee Colony Monitoring

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We present a bumblebee colony monitoring system, BumbleBEEP. The system is fitted with thermometers and a custom weight sensor. These record data up to every 15 min, recording bumblebee brood nest temperature, environmental ambient temperature, and colony growth.

Genetic variation in Turkish honeybees Apis mellifera anatoliaca, A. m. caucasica, A. m. meda (Hymenoptera: Apidae) inferred from RFLP analysis of three mtDNA regions (16S rDNA-COI-ND5)

open access: yesEuropean Journal of Entomology, 2012
In this study, the genetic structure of Turkish honey bee (Apis mellifera L.) populations, mainly obtained from the Central Anatolian region, were investigated at three different mitochondrial regions.

Forest edges buffer effects of agricultural management on bee–plant interaction networks

open access: yesEcological Entomology, EarlyView.
Agricultural management effects: Organic and conventional crop margins host similar bee and plant species, but network structure differs: organic farms exhibit higher interaction diversity, conventional farms higher connectance. Role of forest edges: Native forest edges stabilize bee–plant networks by providing continuous floral resources and suitable ...

Influence of elevation, climate, snowmelt and floral abundance on body size of solitary bees

open access: yesEcological Entomology, EarlyView.
We measured body size in bee species from a 10‐year specimen collection from Colorado sub‐alpine meadows (2450–3450 m) and tested effects of elevation and annual snowmelt, climate and floral abundance. 2 out of 4 bee species collected across a broad elevation range showed a decline in body size with higher elevations; the other two showed no effect ...

The role of artificial nesting boxes and birds’ nests in maintaining vital activity of the Vespidae and Apidae families

open access: yesБіологічні студії, 2022
Background. During 2019‒2021, from the first decade of March to the third decade of July on the territory of northeastern Ukraine, ornithological studies on hollow-nesting birds populating artificial nestings were carried out.

Dietary selectivity mediates niche overlap and interspecific competition in a reedbed warbler community in southern Europe

open access: yesIbis, EarlyView.
Sympatric species are expected to use resources differently along one or more ecological dimensions. This can be complex when there is partial separation along multiple dimensions, such as where bird species exhibit similarities in habitat use and diet.

Diet breadth shapes gut microbiota in the invasive hornet Vespa velutina

open access: yesInsect Conservation and Diversity, EarlyView.
Dietary and microbial profiles of V. velutina larvae are dominated by Apidae and Firmicutes, respectively. DNA metabarcoding of larval meconium and gut samples reveals a significant positive correlation between prey richness and bacterial diversity in the invasive hornet V. velutina. Multiple significant correlations exist between dietary and microbial

A survey of the genus Ceratina Latreille (Hymenoptera: Apidae) in northern Iran, with three new records [PDF]

open access: yesJournal of Insect Biodiversity and Systematics, 2016
A field survey of the bee fauna was conducted in the north of Iran during 2009 to 2015. Special concern was given to the tribe Ceratinini (Hymenoptera; Apidae). Ten species of the genus Ceratina were collected and identified in the present study.

Pollination of Sedirea japonica (Orchidaceae) by Bombus diversus diversus (Hymenoptera: Apidae)

open access: yesEuropean Journal of Entomology, 2013
There are no records of the pollinators of many orchids even though the Orchidaceae are often cited as the example of an intimate relationship between plants and their pollinators.

Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges

open access: yesInsect 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 ...
