Question 1

paper name:

Answer 1

Honeybee navigation: Nature and Calibration of the “odometer”

Question 2

2 theories as to how honeybees estimate the distance of food

Answer 2

• distance flown is estimated in terms of energy consumption
• cue is visual & is derived from the extent to which the image of the world has moved on the eye during the trip

Question 3

methods:

Answer 3

tested observing dances of bees that have flown through a narrow tunnel to collect food reward, 4 experiments.
–> random patterns on sides

Question 4

overall results

Answer 4

the honeybees “odometer” is visually driven,

- also provide calibration of the dance & the odometer in visual terms

Question 5

distance And direction communicated through

Answer 5

waggle dance.

Question 6

experiment 1 & 2 realists:

Answer 6

1) at 35m = round dance 85.2% off bees

2) at 41m = WAGGLE (figure of 8) dance

Question 7

exp 3:

Answer 7

lined with axially orientated steps (parallel to the direction of flight) = negligible image motion cues
= 41m same as exp 2 but 86.7% = round dance

Question 8

exp 4:

Answer 8

random texture, 12m away but WAGGLE DANCE 87.5%

Question 9

waggle dance duration and distance correlation

Answer 9

• duration of dance increases approx. linearly with distance flown up to 1km

Question 10

bees who travelled 35m outside, 6m in tunnel danced to represent

Answer 10

250m

Question 11

tunnel magnifies % of distance by

Answer 11

factor of 31
