This obstacle is present in all communication modalities, forcing organisms to develop diverse mechanisms to overcome noise. Honey bees will modify combs to improve signal efficiency of substrate-borne vibrations, but it is unknown whether, and if so, how, bees compensate for the largest potential source of noise: the bees themselves. The number of bees in a colony changes markedly throughout the year, but the size of the nest cavity does not, forcing workers into high densities on the combs. How, then, do bees communicate via substrate-borne vibrations on combs that are covered in bees? We used accelerometers to measure comb vibrations, while varying the number of workers on the comb. Surprisingly, comb vibrations decreased with increased worker number. Furthermore, inserting freshly killed bees to the comb demonstrated that it is not simply the bees’ collective mass that damps vibrations, but is probably their behavior. We propose that their posture damps vibrations, with each bee linking up to six neighboring cells with her legs. This collective damping reduces background noise and improves the landscape for communication. These results demonstrate how living systems, including superorganisms, can overcome physical obstacles with curiously simple and elegant solutions.</dcterms:abstract> <dc:contributor>Smith, Michael L.</dc:contributor> <dc:contributor>Chen, Po-Cheng</dc:contributor> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <bibo:uri rdf:resource=""/> <dspace:isPartOfCollection rdf:resource=""/> <dcterms:available rdf:datatype="">2019-07-01T11:36:30Z</dcterms:available> </rdf:Description> </rdf:RDF>
