“…Agricultural exploitations and commercial beekeeping practices are regular in Osječko-Baranjska (encompassing both Kozarac and Vardarac apiaries). Grasslands, fruit trees (apple and plum), and intensive commercial crops such as rapeseed, wheat, sunflower, corn, soybeans and barley surrounded the agricultural apiary 30,64,65 . A similar terrain enclosed the semi-natural apiary, although with greater presence of natural flora due to its proximity (< 3 aerial km) to sedges, reed beds, scrublands and wetlands belonging to the Kopački Rit Nature Park 65 .…”

Honeybee health and the species’ gut microbiota are interconnected. Also noteworthy are the multiple niches present within hives, each with distinct microbiotas and all coexisting, which we termed “apibiome”. External stressors (e.g. anthropization) can compromise microbial balance and bee resilience. We hypothesised that (1) the bacterial communities of hives located in areas with different degrees of anthropization differ in composition, and (2) due to interactions between the multiple microbiomes within the apibiome, changes in the community of a niche would impact the bacteria present in other hive sections. We characterised the bacterial consortia of different niches (bee gut, bee bread, hive entrance and internal hive air) of 43 hives from 3 different environments (agricultural, semi-natural and natural) through 16S rRNA amplicon sequencing. Agricultural samples presented lower community evenness, depletion of beneficial bacteria, and increased recruitment of stress related pathways (predicted via PICRUSt2). The taxonomic and functional composition of gut and hive entrance followed an environmental gradient. Arsenophonus emerged as a possible indicator of anthropization, gradually decreasing in abundance from agriculture to the natural environment in multiple niches. Importantly, after 16 days of exposure to a semi-natural landscape hives showed intermediate profiles, suggesting alleviation of microbial dysbiosis through reduction of anthropization.
