Journal ArticleDOI
A landscape-scale study of bumble bee foraging range and constancy, using harmonic radar
Juliet L. Osborne,Suzanne J. Clark,R.J. Morris,Ingrid H. Williams,J. R. Riley,Alan D. Smith,Don R. Reynolds,A. S. Edwards +7 more
TL;DR: The results support the hypothesis that bumble bees do not necessarily forage close to their nest, and illustrate that studies on a landscape scale are required if the authors are to evaluate bee foraging ranges fully with respect to resource availability.
Journal ArticleDOI
The flight paths of honeybees recruited by the waggle dance
TL;DR: Using harmonic radar to record the actual flight paths of recruited bees, this work provides a quantitative description of how effectively recruits translate the code in the dance into flight to their destinations.
Journal ArticleDOI
Honey bees navigate according to a map-like spatial memory
Randolf Menzel,Uwe Greggers,Alan D. Smith,Sandra Berger,Robert Brandt,Sascha Brunke,Gesine Bundrock,Sandra Hülse,Tobias Plümpe,Frank Schaupp,Elke Schüttler,Silke Stach,Jan Stindt,Nicola Stollhoff,Sebastian Watzl +14 more
TL;DR: Harmonic radar data suggests a rich, map-like organization of spatial memory in navigating honey bees, which can set course at any arbitrary location in their familiar area, and choose between at least two goals.
Journal ArticleDOI
Community-wide vaccination with the heptavalent pneumococcal conjugate significantly alters the microbiology of acute otitis media.
Stan L. Block,James Hedrick,Christopher J. Harrison,Ron Tyler,Alan D. Smith,Rebecca Findlay,Eileen Keegan +6 more
TL;DR: The overall proportion of S. pneumoniae isolates and vaccine serotypes in AOM were significantly reduced by community-wide use of PCV7 vaccine in the practice of this 7-clinician, pediatric practice in rural central Kentucky.
Journal ArticleDOI
Ontogeny of orientation flight in the honeybee revealed by harmonic radar
Elizabeth A. Capaldi,Alan D. Smith,Juliet L. Osborne,Susan E. Fahrbach,Sarah M. Farris,Don R. Reynolds,A. S. Edwards,Andrew P. Martin,Gene E. Robinson,Guy M. Poppy,J. R. Riley +10 more
TL;DR: Using harmonic radar, it is shown for the first time a striking ontogeny to honeybee orientation flights, suggesting a learning process adapted to changes in weather conditions, flower availability and the needs of bee colonies.
