Spatio-temporal variation in pollen collected by honey bees (Apis mellifera) in rural-urban mosaic landscapes in Northern Europe

Pollen is a source of protein, lipids, vitamins and minerals for bees and other flower-visiting insects. The composition of macro- and micronutrients of pollen vary among different plant species. Honey bees are long-distance foragers, collecting nectar and pollen from plants within several kilometers of their hive. Availability of pollen within the foraging range of honey…

Pollen Identification: The Challenges of Color-Based Classification

Pollen analysis is crucial for studying plant-pollinator interactions, biodiversity, and environmental change. Traditional methods include microscopic examination and modern chromatic assessments. Color-based classification is appealing for its simplicity, but the significant color similarity between different plant species’ pollen grains remains a challenge. In our latest study, we analyzed over 85,000 corbicular pollen samples from 30…

9th EurBee Congress 2022 in Belgrade, Serbia

On behalf of the European Association for Bee Research (EurBee) I have the great honour and pleasure to invite you to attend the 9th Congress of Apidology (EurBee 9) convened under the motto: “Save the bees for our future”. The conference intends to promote knowledge exchange and international cooperation and to enable the further exchange…

Pollination and Plant Reproductive Success of Two Ploidy Levels in Red Clover (Trifolium pratense L.)

Plant reproduction in red clover requires cross-fertilization via insect pollination. However, the influences of visitation rate and timing on maximizing ovule utilization are yet to be determined. We aimed to study the influences of visitation rate, flowering stage, and self-incompatibility on reproductive success. We applied hand and honey bee pollination in the study of eight…

Different pollination approaches to compare the seed set of diploid and tetraploid red clover Trifolium pratense L.

In red clover seed production, low seed yield is limiting the commercial exploitation of tetraploid red clover. To explore if pollination is the limiting factor for the seed yield in tetraploid red clover, we investigated pollinator behaviour and plant reproductive success in diploid (2x) cultivar ‘Rajah’ and tetraploid (4x) cultivar ‘Amos’ using honey bee and…
