We discuss various strategies for locating nests of the rare and endangered above-ground nesting bumblebee species Bombus muscorum. Although we did not find any nests, we were able to track bees marked with paper strips for up to 800 m. @jki-research.bsky.social @nabu.de doi.org/10.1111/icad...

Happy to share our latest publication with you. 🧵 Trees are often overlooked as relevant bee forage ressources. Realising that there is relatively little known about bees in flowering tree canopies, we searched for data and methodologies to tackle this gap. @jki-research.bsky.social

Researchers at our Institute for #Bee Protection are currently collecting data on the occurrence of honeybees and wild bees in agricultural landscapes. Systematic data collection over several years will provide a robust reference for future interval monitoring. #WorldBeeDay www.julius-kuehn.de/en/bs
Some of the survey sites are located in intensively managed agricultural areas. Just in these locations, the field margins show an unexpectedly diverse flora during the course of the year (note the difference between end of March and beginning of May 2025). At this site, located in the Salzland district of Saxony-Anhalt, the halictid bee (Lasioglossum xanthopus) visits flowers of field bugloss (Lycopsis arvensis), among others.
Photo: Dr Severin Polreich/JKIResearchers at the JKI Institute for Bee Protection collect pan-trap samples. The spectrum of bee species and other flower-visiting insects is determined using DNA metabarcoding later on. 
Photo: Dr Severin Polreich/JKIHedges are important landscape elements, providing not only food but also nesting opportunities and sun-exposed surface for warming up and resting (here on field maple, Acer campestre), which may also have a positive effect on the pollination activity of bees in the cooler spring.

Pollinator, pollen, and cultivar identity drive crop quality
Animal pollination enhances a third of global food production, yet the roles of pollinator, pollen, and cultivar identity in shaping crop quality, such as nutritional, sensory, and marketing value, are underexplored. Crop quality often depends on pollinator movement patterns, which vary with cultivar selection and spatial arrangement, pollen donor identity, and landscape context. Transfer of the right pollen between cultivars may fail, as pollen is often not transported far, even by highly dispersive pollinators, reducing cross-pollination and crop quality. Both pollinator identity and complementary spatiotemporal activity of diverse pollinators can shape crop quality. Here, we argue that promoting crop quality needs better understanding of species-specific pollinator behaviour and cultivar distribution patterns, rather than only focusing on enhancing pollinator densities.
