Biodiversity, conservation and current threats to European honeybees

Europe contains several endemic *Apis mellifera* subspecies and evolutionary lineages whose present distribution reflects both post-glacial biogeography and centuries of beekeeping. The review explains how migratory beekeeping, queen trade, and honeybee promiscuous mating increase introgressive hybridization between native and managed non-native subspecies, potentially erasing locally adapted genetic combinations such as the Western European black bee lineage. It summarizes the main European subspecies, natural and human-mediated hybridization zones, country-level conservation and breeding programs, and wider threats that contribute to honeybee decline and economic losses. The paper argues that conserving native European honeybee diversity is important both for resilient apiculture and for ecosystem pollination services, and it calls for stronger genetic monitoring, protected breeding areas, and coordinated research across Europe.

Relevancy to Gratheon

This review is relevant to Gratheon's colony-health and apiary-intelligence roadmap because it frames "bee health" as more than a single-hive sensor problem. For the web app, subspecies, breeding origin, queen replacement history, and nearby migratory apiary pressure could become metadata that explains abnormal behavior, overwintering performance, disease susceptibility, or poor pollination outcomes. For Gratheon hardware, entrance traffic, queen-state, temperature, acoustic, and parasite signals should be interpreted against local genetics and regional conservation rules rather than assuming all colonies are biologically equivalent. In the long-term autonomous-apiary vision, the paper supports features that help beekeepers avoid unintentionally weakening local adaptations: tracking queen lineage, recommending locally appropriate stock, and surfacing conservation risks when moving colonies or buying queens.
