Foraging distances, habitat preferences and seasonal colony performance of honeybees in Central European forest landscapes

Journal of Applied Ecology, Journal Year: 2023, Volume and Issue: 60(6), P. 1056 - 1066

Abstract Unmanaged forest is considered as native habitat of the Western honeybee Apis mellifera and assumed to provide important pollen nectar sources. However, resource supply might be spatially temporally restricted in managed forests landscape‐scale studies European regions are currently lacking. Capitalizing on a unique communication behaviour, waggle dance, we investigated foraging deciduous region southern Germany. We analysed 2022 dances performed by bees 12 colonies placed centre landscapes with varying degree cover (50%–99% at 2‐km radius) from March August 2019, thereby identifying distances preferences over almost an entire season. By connecting dance information colony weight recordings, assessed role landscape composition contribution different types gain. Foraging generally increased amount surrounding pointing inferior food resources forest. Yet, this effect strongly depended season was more pronounced for than foraging. Even though forest‐dominated had fly further, not significantly affected cover. Compared expectations based proportions habitats, foraged frequently grassland cropland coniferous forests, late summer being especially difficult period forests. During phase gain early summer, use nectar/honeydew close expectation, highlighting complementary source carbohydrates during short periods year. Policy implication. The ecological economic value honeybees could continuous provision floral resources, Therefore, recommend diversifying stands insect‐pollinated trees, permitting secondary successions gaps, larger scales, creating high diversity. This will only help native, wild‐living beekeepers' residing areas but also foster social general.

Tropical and montane Apis cerana show distinct dance-distance calibration curves

Journal of Experimental Biology, Journal Year: 2024, Volume and Issue: 227(13)

Published: June 10, 2024

Social bees have evolved sophisticated communication systems to recruit nestmates newly found food sources. As foraging ranges can vary from a few hundred meters several kilometers depending on the environment or season, populations of social bee species living in different climate zones likely show specific adaptations their recruitment communication. Accordingly, studies western honey bee, Apis mellifera, demonstrated that temperate exhibit shallower dance-calibration curves compared with tropical populations. Here, we report first comparison calibration for three Indian cerana lineages: indica, and two montane Himalayan (Himachal Pradesh) kashmirensis (Jammu Kashmir). We colonies A. dance-distance significantly slopes than those indica. Next, transferred c.

However, were also higher tested original habitat, indicating an important effect environment. coding between resemble described suggesting both independently similar adaptations.

Can honey bees be used to detect rare plants? Taking an eDNA approach to find the last plants in a weed eradication program

Environmental DNA, Journal Year: 2023, Volume and Issue: 5(6), P. 1516 - 1526

Abstract The detection of rare taxa, crucial to conservation and biosecurity, presents many challenges that emerging technologies have the potential address or avoid. Analysis environmental DNA (eDNA) is a promising tool for species, especially when applied in way exploits natural processes accumulate biological material (natural aggregation). This study investigated using honey bees as aggregators pollen eDNA detect Chrysanthemoides monilifera subsp. (boneseed), an introduced species targeted eradication Western Australia. We developed species‐specific polymerase chain reaction (PCR)‐based assay detected boneseed at levels low 70 grains per million constructed mixture. was successfully used on wild‐caught from large populations, confirming they collect pollen. However, our results did not bee collected hive traps near isolated plants. hypothesize combination abundance individuals, vast alternative flower resources time flowering, behavior ecology may led lack detection. propose ways which future work can be improved. also outline how other substrates (e.g., air water samples) could with PCR we developed.

Landmark knowledge overrides optic flow in honeybee waggle dance distance estimation

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2024, Volume and Issue: unknown

Published: June 10, 2024

Abstract Honeybees encode in their waggle dances the vector (distance and direction) of an outbound flight to a food source or new nest side. Optic flow has been identified as major information distance estimation. Additional components estimation were also identified, e.g. sequence experienced landmarks. Here we address question whether bees use landscape memory developed during exploratory orientation flights estimate distance. We took advantage fact that narrow tunnel lead further measures due higher optic flow. find this effect is lost when had explored area which located they have somewhat restricted visual access surrounding environment through mesh on top tunnel. These data are interpreted context other findings about structure navigational develops flights. In particular, suggest embed into representation space stores previously features. Summary statement The code honeybee dance embedded establish foraging
