Dataset Description (Abstract): Code and data used in Pritchard & Vallejo-Marin (2020) published in Journal of Experimental Biology doi:10.1242/jeb.220541 Abstract: Vibrations play an important role in insect behaviour. In bees, vibrations are used in a variety of contexts including communication, as a warning signal to deter predators and during pollen foraging. However, little is known about how 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 during pollen foraging on two buzz-pollinated plants (Solanum, Solanaceae). Using laser vibrometry, we were able to obtain contactless measures of both the frequency and amplitude of the thoracic vibrations of bees across the three behaviours. Despite all three types of vibrations being produced by the same power flight muscles, we found clear differences in the mechanical properties of the vibrations produced in different contexts. Both floral and defensive buzzes had higher frequency and amplitude velocity, acceleration, and displacement than the vibrations produced during flight. Floral vibrations had the highest frequency, amplitude velocity and acceleration of all the behaviours studied. Vibration amplitude, and in particular acceleration, of floral vibrations has been suggested as the key property for removing pollen from buzz-pollinated anthers. By increasing frequency and amplitude velocity and acceleration of their vibrations during vibratory pollen collection, foraging bees may be able to maximise pollen removal from flowers, although their foraging decisions are likely to be influenced by the presumably high cost of producing floral vibrations.
Dataset Description (TOC): From the README. This folder contains all the code and data necessary to replicate our data processing and analysis. Currently the folder is in the final state, will all data processed and summarised. To replicate analysis and figures you can use the data in the final state, ignore markdown docs 1 & 2 and only use 3. Analysis and Figures.rmd. To replicate data processing, delete the .data files (but not folders or csv files) in the processed data folder and the "allData**.csv" files (but not the "**IT.csv") and run the code in docs 1& 2. In the SOFTWARE folder there is also the files needed to collect data from two sensors using LABVIEW and a compactRIO device. See for usage instructions. Dedicated UnZip software is recommended for accessing the dataset, for example, IZArc.
