Diversity and abundance of solitary and primitively eusocial bees in an urban centre: a case study from Northampton (England) [PDF]

, 2015
The apparent reduction of solitary and primitively eusocial bees populations has remained a huge concern over the past few decades and urbanisation is considered as one of the factors affecting bees at different scales depending on bee guild.

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 ...

Patterns of size variation in bees at a continental scale: does Bergmann’s rule apply [PDF]

, 2018
Body size latitudinal clines have been widley explained by the Bergmann’s rule in homeothermic vertebrates. However, there is no general consensus in poikilotherms organisms in particular in insects that represent the large majority of wildlife.

Mitochondrial heteroplasmy and DNA barcoding in Hawaiian Hylaeus (Nesoprosopis) bees (Hymenoptera: Colletidae)

BMC Evolutionary Biology, 2010
Background The past several years have seen a flurry of papers seeking to clarify the utility and limits of DNA barcoding, particularly in areas such as species discovery and paralogy due to nuclear pseudogenes.
