Pollinator visits increase with bloom amount but decline with building height on extensive green roofs

Insect Conservation and Diversity, Volume 18, Issue 3, Page 438-445, May 2025.
Pollinator abundance and species richness decline with building height. Although our study was limited to eight sites, it emphasises the importance of extensive green roofs (EGRs) on low‐rise buildings. Bee abundance and species richness increased with stonecrop bloom amount, but communities determined from distinct stonecrop species were more alike to

Landscape influence on pollinator population genetic connectivity

Insect Conservation and Diversity, Volume 18, Issue 3, Page 285-302, May 2025.
We analysed 113 studies from 59 countries, covering 96 bee and 21 hoverfly species, to review the evidence of environmental and landscape effects on the population genetic connectivity in pollinators. Environmental conditions (precipitation and temperature), topography (elevation and sea), and land use (agriculture, deforestation, urbanisation) were ...

The genome sequence of the Large Sharp-tail Bee, Coelioxys conoideus (Illiger,1806) [version 1; peer review: 2 approved]

Wellcome Open Research, 2023
We present a genome assembly from an individual female Coelioxys conoideus (the Large Sharp-tail Bee; Arthropoda; Insecta; Hymenoptera; Megachilidae). The genome sequence is 417.6 megabases in span.

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 ...

Establishment of Wildflower Islands to Enhance Roadside Health and Aesthetics [PDF]

, 2019
Wildflowers are crucial in the ecological function of the low-input roadside plant communities in terms of water andnutrient cycling, nutrient inputs such as nitrogen, total plant canopy cover, stand longevity, and provision of habitat for numerous small

Potential effects of oilseed rape expressing oryzacystatin-1 (OC-1) and of purified insecticidal proteins on larvae of the solitary bee Osmia bicornis [PDF]

, 2008
Despite their importance as pollinators in crops and wild plants, solitary bees have not previously been included in non-target testing of insect-resistant transgenic crop plants.
