The survey of wild bees (Hymenoptera, Apoidea) in Belgium and France
The strong regression of long-tongued species seriously threatens the maintain of an appropriate pollination level of wild and cultivated plants and the lessened availability or suitability of open areas due to afforestation, urbanisation or agricultural intensification. Expand
The authors studied the faunistic drift in Apoidea of Belgium by comparing the relative number of species before and 1950 onwards and found a strong relative regression of cleptoparasites, which strongly affects long tongue species and seriously threatens the maintain of an appropriate pollination level of wild and cultivated plants.

Phylogeny of Halictidae with an emphasis on endemic African Halictinae
A phylogenetic analysis of tribal, generic, and subgeneric relationships within the subfamily Halictinae using a combined data set of three nuclear genes: long-wavelength opsin, wingless, and EF-1α is presented. Expand
DNA barcoding and male genital morphology reveal five new cryptic species in the West Palearctic bee Seladonia smaragdula (Vachal, 1895) (Hymenoptera: Apoidea: Halictidae).
Five variants of the West Palearctic sweat bee Seladonia smaragdula are recognized and described as five new species using DNA barcoding and morphological characters, primarily of the male genitalia. Expand
An updated checklist of bees of Sri Lanka with new records
The updated checklist of bees of Sri Lanka is based on field collections made in 29 locations covering all the biogeographic regions in the island. The study resulted in the addition of 16 speciesExpand
Mechanism of self-pollination in Hybanthus enneaspermus (L.) F. Muell. and notes on the floral biology of some Rinorea species (Violaceae) in Ivory Coast
Results from field work in Ivory Coast and from the examination of cultivated plants of three species in the two largest tropical genera, Rinorea and Hybanthus, showed that self-pollination, with viable seeds production, appears likely in H. enneaspermus. Expand
Addition to the checklist of IUCN European wild bees (Hymenoptera: Apoidea)
The authors discuss the artificial framework of the study considered by International Union for Conservation of Nature (IUCN) to produce the first Red List and they propose the more meaningful West Palaearctic biogeographical region. Expand
Using next-generation sequencing to improve DNA barcoding: lessons from a small-scale study of wild bee species (Hymenoptera, Halictidae)
This work simultaneously sequencing five markers (including the DNA barcode and a diagnostic marker of Wolbachia) in 12 species of Halictidae that were previously DNA barcoded using Sanger sequencing to improve the phylogeny of the group, detected Wolbachian infections and characterised haplotype variants.
