“…Significantly distinct habitats e.g., grasslands and forests or urbanized areas and natural habitats, can drive the difference in floral pollen resources (Smart et al 2017). However, within similar habitat types, floral pollen resource availability may be significantly different (Cannizzaro et al 2022). Furthermore, honeybees tend to forage specific floral resources intensively when they are abundant around their foraging areas (Geslin et al 2017), supporting our finding that a high number of taxa of the pollen resources overlaped between forests and national parks.…”

We investigated the floral resources of the honeybee (Apis mellifera) by pollen DNA metabarcoding as the first step in honeybee conservation. We attempted to identify as many floral resources and as wide resource availability as possible in areas and compared the richness of floral resources between forests and national parks. We found that both forest and national parks can sufficiently support honeybee floral resources; however, national parks were more stable habitats with more complex vegetation structure than those of forests. Also, honeybee's preferences for floral resources were determined using niche breadth, niche overlap, and network analysis among the floral resources in forest areas. Quercus and Actinidia were the most frequently detected taxa of pollen resources in both forests and national parks by pollen metabarcoding. Even though we anticipated that more various pollen resource taxa would be found in national parks than forests, no differences in the number pollen resource taxa were detected between them. According to the niche overlap analysis result, the honeybee preferred the pollen resources in both forests and national parks, and the co-occurrence pattern analysis of pollen resource taxa in both forests and national parks showed a simple network. Altogether, our findings suggested that DNA metabarcoding of pollen collected by the honeybee can provide useful information on the flowering plants in a given area. As the use of floral pollen resources varies spatially and temporally, periodic monitoring of pollen resources can identify which pollen is required to maintain the health of honeybee colonies.

“…This tells us that lands with more diverse resources improved overall colony survival, likely by providing a higher diversity and volume of pollen and nectar (Naug, 2009). Similar patterns were found recently in Canada (Richardson et al, 2023), and more diverse pollen collection, a key for good nutrition, was also linked to natural landscapes in Great Britain (Woodcock et al, 2022), France (Odoux et al, 2012) and Papua New Guinea (Cannizzaro et al, 2022). A wide variety of pollen can even work synergistically to improve honeybee health (Donkersley et al, 2017).…”

Pollinator declines across the globe are centrally driven by a synergistic interaction between intensive land use, pesticides, and climate change. Competition between managed and wild pollinators has been a growing topic of research, however the ensuing social conflict builds antagonism between beekeepers and conservationists, two parties that have an interest in protecting natural diversity for pollinators. The threats perpetuating this potential for competition are as real for managed bees as wild species and uniting both groups, wherever possible, can create long lasting and meaningful change in current agricultural practices. This review examines the most recent literature on pollinator competition and the common threats that drive it. It also delves into the social elements of beekeeping and examines the potential for beekeepers to contribute to the protection of natural habitats. Beekeepers have a genuine interest to preserve natural space and with their charismatic species, dutiful observations, and innovative techniques, they can be valuable assets in filling knowledge gaps and generating public interest. Pollinator strategies in the future should include beekeepers as key stakeholders if their impacts are to be improved.

“…Based on our results, the composition of land cover in Kerinci, which is still dominated by natural forest, supported more pollen sources from different plant species (16 pollen types) for A. dorsata than the composition of plantationdominated landscape in Kampar (3 pollen types) (Figure 6). A similar pattern also occurred in A. mellifera, where the forest landscape increased the diversity in honeybee diets, particularly trees, which were the dominant floral source of bee bread (Cannizaro et al, 2022). Apis cerana also collected more pollen types as a food diet in deciduous forests (16-28 pollen types) than in agricultural regions (9-16 pollen types) (Jhansi et al, 1994).…”

IntroductionApis dorsata, the common bee pollinator in tropical forests, is experiencing a population decrease due to several anthropogenic factors that lead to land cover changes and habitat loss. Land cover changes may alter their resource supply and foraging behavior. Our study aimed to determine foraging behavior and botanical origin using pollen of A. dorsata honey in two land cover types: plantationdominated landscape (PL) in Kampar (Riau) and forest-agriculture-dominated landscape (FL) in Kerinci (Jambi) Sumatra, Indonesia.MethodsWe observed two colonies of A. dorsata flight direction and flight activities in each land cover from 9 am–3pm. Honey was harvested from both nests of A. dorsata and the pollen in the honey was analyzed using acetolysis procedure. Vegetation analysis in both locations was conducted based on the flight directions of the giant honey bees.ResultsThe foraging data of A. dorsata showed a difference in the total number of bees between these two land cover types. The number of bees flying out and returning to the nest was higher in Kerinci than in Kampar, while high morning foraging activities were recorded in both land cover types. Furthermore, the foraging activity of the colonies in the PL landscape, i.e., flying out and returning to the nest with and without pollen, decreased at noon. The palynological results of the honey showed that in the PL landscape, pollen diversity was very low and mainly consisted of Elaeis gueneensis pollen (97%). Meanwhile, pollen types and concentrations were much higher in the FL than in the PL.DiscussionThis result suggests that A. dorsata exhibits a more varied foraging behavior in a diverse and heterogeneous landscape in Kerinci compared to a plantation-dominated habitat in Kampar.
