... the biomechanical properties of bee vibrations vary across multiple behaviours within a species. In this study, we compared the properties of vibrations produced by Bombus terrestris audax (Hymenoptera: Apidae) workers in three contexts: during flight, during defensive buzzing, and in floral vibrations produced...

... in the early stages of understanding how bee and floral characteristics affect the production and transmission of floral vibrations. Here, we analysed floral vibrations produced by four closely related bumblebee taxa ( Bombus spp.) on two buzz-pollinated plants species ( Solanum spp.). We measured floral...

... of wing wear are unresolved. In this paper, we examine whether wing use while foraging explains wing wear in bumble bees ( Bombus spp.). Wing wear may result from three distinct flight characteristics during foraging: time spent in flight, flight frequency and frequency of wing collisions with vegetation...

... lifting) to determine both the intraspecific allometry of and methodological differences in estimates of maximum flight performance for the bumblebee Bombus impatiens . We found that incremental mass addition underestimated maximum lifting capacity by approximately 18% relative to values obtained...

... is also vital to bees and exhibits a greater than 20-fold range in protein quality. We provide the first demonstration that bee T th is also correlated with pollen quality. We allowed bumble bee, Bombus impatiens , foragers from two colonies to collect pollen varying in quality (25%, 50%, 75% and 100...

.... Using infrared thermography, we measured T th for Bombus wilmattae foragers (mass 0.17±0.11 g, length 15.0±1.5 mm) from six wild colonies,foraging on a range of sucrose concentrations (0.5-2.5 mol l -1 ,16-65% by mass) in foraging arenas. For all colonies, we measured significant increases in Δ T th ( P...

... activities of FbPase (0.7-19.7 units g -1 thorax) in North American Bombus species, with the exception of Bombus rufocinctus , where activity (43.1 units g -1 thorax)is comparable with that of European congeners. These data, taken with estimates of maximal rates of heat production by cycling, do not support...
