DNA in honey could describe the changes in flower visits and microbe encounters of honey bees over decades

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Abstract Recent environmental changes due to land-use and climate change threaten biodiversity the ecosystem services it provides. Understanding true scope of these is complicated by lack historical baselines for many interactions underpinning services, such as pollination, or disservices, disease spreading. To assess in vital find ways comparing past current between species. Here, we focus on honey bees – one world’s most important agricultural pollinators, plants they visit, microbes encounter environment. DNA offers insights into contemporary bees. Old samples could serve describe bees’ previous decades, providing a baseline against which over time. By identifying taxonomic origin plant, bacterial fungal fifty-year-old samples, show that plant can reveal visited past. Likewise, microbe records microbes, including pollinator pathogens, encountered possibly spread. However, some differences recovered old new suggest degradation different bias naive comparisons samples. Like other types ancient may be useful historically occurred should not taken proof an interaction did occur. Keeping limits data mind, time series offer unique information about how associations with flowers have changed during decades change.

The Latitudinal Biotic Interaction Hypothesis revisited: contrasting latitudinal richness gradients in actively vs. passively accumulated interaction partners of honey bees

BMC Ecology and Evolution, Journal Year: 2025, Volume and Issue: 25(1)

Published: March 17, 2025

Abstract Background Contrasting hypotheses suggest that the number of biotic interactions per species could either increase towards equator due to increasing richness potential interaction partners (Neutral theory), or decrease in tropics increased competition (Latitudinal Biotic Interaction Hypothesis). Empirical testing these remains limited practical limitations, differences methodology, and turnover across latitudes. Here, we focus on a single with worldwide distribution, honey bee ( Apis mellifera L.), assess how different types vary Foraging bees interact many organisms their local environment, including plants they actively select visit microbes largely encounter passively (i.e., unintentionally more less randomly). Tissue pieces spores are carried hive by foraging end up preserved within honey, providing rich record nature. Results Using samples from around globe, show while plant taxa at higher latitudes, bacteria tropics. Conclusions These components bees’ niche support latitudinal hypothesis for actively-chosen interactions, but consistent neutral theory (assuming greater bacterial tropics) unintentional interactions.

Antibiotic Use in Beekeeping: Implications for Health and Environment from a One-Health Perspective

Antibiotics, Journal Year: 2025, Volume and Issue: 14(4), P. 359 - 359

Published: April 1, 2025

Background: The use of antibiotics in beekeeping has potential implications for honeybee health and environmental contamination. Recent research indicates that extensive antibiotic beekeeping, especially oxytetracycline, promotes antimicrobial resistance bee-related bacteria. Honeybees can transport oxytetracycline-resistance genes during foraging, potentially establishing reservoirs the colony facilitating intergeneric gene transfer among various gut bacteria as well microbiome flowers wider environment, where honeybees spread antibiotic-resistance over a large distance. This study investigates effects oxytetracycline hydrochloride (OTC) treatment on from One Health perspective, examining residues honey, spread, presence tetracycline-resistance (TET-RGs). Methods: In spring 2022, two groups four hives were placed near an almond grove Central Italy. group was treated with 1.68 g OTC, while other remained untreated. Samples collected bees, hive entrances, before at 3 9 days post-treatment. OTC TET-RGs analyzed to assess contamination dissemination. Results: detected honey both (day 3: 263,250.0 ± 100,854.3 µg/kg; day 9: 132,600 146,753.9 µg/kg) untreated 20.5 8.2 135.8 198.6 µg/kg), suggesting cross-contamination. Residues also found tree (0.7 0.1 (tet(K), tet(L), tet(M), tet(B), tet(O), tet(D)) pre- bacteria, (tet(M), tet(A), tet(D), tet(B)) appeared post-treatment groups. No significant correlation observed between distance flowers, although farms located within bees’ flight range, which might have been used past, could influenced results. Conclusions: These findings highlight risk OTC-induced cross-contamination TET-RG, raising concerns bee safety. Given honeybees’ social nature negative their health, antibiotic-free management approach is recommended sustainable apiculture.

Deciphering Molecular Mechanisms and Diversity of Plant Holobiont Bacteria: Microhabitats, Community Ecology, and Nutrient Acquisition

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(24), P. 13601 - 13601

Published: Dec. 19, 2024

While gaining increasing attention, plant–microbiome–environment interactions remain insufficiently understood, with many aspects still underexplored. This article explores bacterial biodiversity across plant compartments, including underexplored niches such as seeds and flowers. Furthermore, this study provides a systematic dataset on the taxonomic structure of anthosphere microbiome, one most niches. review examines ecological processes driving microbial community assembly interactions, along discussion mechanisms diversity concerning acquisition nitrogen, phosphorus, potassium, iron—elements essential in both molecular contexts. These insights are crucial for advancing biology, ecology, environmental studies, biogeochemistry, applied studies. Moreover, authors present compilation markers discussed processes, which will find application (phylo)genetics, various (meta)omic approaches, strain screening, monitoring. Such can be valuable source information specialists fields concerned researchers, contributing to developments sustainable agriculture, protection, conservation biology.
