Our understanding of individual response behaviour and how it is integrated into a functioning colony is still patchy. Most theoretical studies addressing this question are based on the assumption that workers have intrinsic and often fixed response thresholds for task-related stimuli. Here, we investigated the plasticity in worker fanning response behaviour in a bumblebee, Bombus terrestris. Using a temperature-controlled brood dummy, we first asked whether the fanning response is modulated by rate of temperature change. Second, we examined to what extent the fanning response is influenced by recent fanning experience. Our results show that the individual fanning response is modulated by both the rate of temperature increase and recent experience. Workers responded at lower temperatures and with a higher probability when the temperature of the brood dummy increased slowly compared with more rapid temperature increases. Workers that repeatedly responded to an increase in brood dummy temperature with fanning showed a significant decrease in their response thresholds, whereas the response thresholds of control workers that experienced the same treatment but did not gather fanning experience remained unchanged. The decrease in response threshold was pronounced when the time interval between two successive fanning events was less than 6 h. When 16 h or more separated fanning events, individual fanning responses returned to higher threshold levels. We suggest that experience-dependent modulation of response thresholds plays an important role in the behavioural differentiation of workers and the flexibility of insect colonies.</dcterms:abstract> <dc:creator>Westhus, Claudia</dc:creator> <dcterms:bibliographicCitation>Animal Behaviour ; 85 (2013), 1. - S. 27-34</dcterms:bibliographicCitation> <dc:language>eng</dc:language> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2013-10-17T07:31:58Z</dc:date> <dcterms:issued>2013</dcterms:issued> <dc:creator>Weidenmüller, Anja</dc:creator> <dc:contributor>Weidenmüller, Anja</dc:contributor> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2013-10-17T07:31:58Z</dcterms:available> <dc:contributor>Roces, Flavio</dc:contributor> <dc:rights>deposit-license</dc:rights> <dcterms:title>Behavioural plasticity in the fanning response of bumblebee workers : impact of experience and rate of temperature change</dcterms:title> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103605204-4002607-1"/> <dc:creator>Kleineidam, Christoph J.</dc:creator> </rdf:Description> </rdf:RDF>
