The bee dance language as a modelJamming the information content of the waggle dance: Jamming the information content of the waggle danceMeasuring foraging success: Measuring foraging success 12,035 kg Daily weight changes of a beehive can be measured on a scale - this reflects mostly nectar intakeSlide18: Temperate habitat (Central European)Slide19: Temperate habitat (Mediterranean)Slide20: Tropical habitat (India) - days of high nectar intake are missing without location communicationSlide21: Benefits of dance communication are limited to the tropical habitatSlide22: temperateSlide23: tropicalSlide24: Spatial aggregation in tropical and temperate habitats Tropics TemperateSlide25: The honeybees originated in tropical Asia You do not have the permission to view this presentation.
