“…We also used VSEARCH to remove reads shorter than 200 bp, complete quality filtering (EE < 1; Edgar & Flyvbjerg, 2015) and de-novo chimera filtering, and define amplicon sequence variants (ASVs), as previously done successfully for pollens (e.g. Wilson et al, 2021). The ITS2 rDNA reads were first directly mapped with VSEARCH global alignments and an identity cut-off threshold of 97% against a floral ITS2 reference database generated with the BCdatabaser (Keller et al, 2020), which consisted of plants recorded within the study regions.…”

“…In organic beekeeping in the south of Western Siberia, a successful solution to the problems of a forage base is the use of natural landscapes with rich entomophilous vegetation. It is social apidaidae strive to increase the species diversity of the collected pollen to provide a complete diet for their larvae [15,16]. This is a biological rationale for the need to provide honey bees with a variety of botanical sources of protein feed, which can be implemented in native biocenoses, on non-agricultural lands.…”

In our research firstly we provide to generalized conceptual basis for the characteristics of organic beekeeping in Russia, second determine the impact of organic beekeeping on the productivity and the third quality of beekeeping products, to assess the possibility. To assess the problems associated with some of the main parameters, we conducted literature review and analysis of beekeeping products obtained in an apiary that implements the principles of organic beekeeping in the south of Western Siberia (Vengerovo village, Novosibirsk region). Article investigates theoretical and practical aspects of the orientation of apiaries to the production of organic products in the context for growing level of competition.

“…Interesting findings of pollen foraging ecology are also available on another generalist social bee species belonging to the tribe Meliponini. It was suggested that this stingless bee species maximizes pollen diversity intake in resource diverse habitats [91,92]. No such predication can so far be made on honey bees, and further research on this topic is recommended.…”

A diverse supply of pollen is an important factor for honey bee health, but information about the pollen diversity available to colonies at the landscape scale is largely missing. In this COLOSS study, beekeeper citizen scientists sampled and analyzed the diversity of pollen collected by honey bee colonies. As a simple measure of diversity, beekeepers determined the number of colors found in pollen samples that were collected in a coordinated and standardized way. Altogether, 750 beekeepers from 28 different regions from 24 countries participated in the two-year study and collected and analyzed almost 18,000 pollen samples. Pollen samples contained approximately six different colors in total throughout the sampling period, of which four colors were abundant. We ran generalized linear mixed models to test for possible effects of diverse factors such as collection, i.e., whether a minimum amount of pollen was collected or not, and habitat type on the number of colors found in pollen samples. To identify habitat effects on pollen diversity, beekeepers’ descriptions of the surrounding landscape and CORINE land cover classes were investigated in two different models, which both showed that both the total number and the rare number of colors in pollen samples were positively affected by ‘urban’ habitats or ‘artificial surfaces’, respectively. This citizen science study underlines the importance of the habitat for pollen diversity for bees and suggests higher diversity in urban areas.
