This service was developed further in 1999 to include real-time presentations of water level data from selected stations in the Baltic.
After completion of maze testing, animals were given alternate-day, free-choice presentations of water and ascending doses of ethanol solutions (2%–10%), followed by a 10-day maintenance period with 10% ethanol.
In addition, those bees that responded to all sucrose concentrations and all presentations of water were excluded from analyses as they appeared not to be able to discriminate between sucrose solution and water.
In addition to calculating the total number of A, B, C and D scores as in Experiment 1, a Laterality Index (LI) was calculated for each bee, using (L−R)/(L+R), where L represents the number of proboscis extensions on presentation of lemon water on the left side and R the number of PER on presentations of lemon water on the right side.
The accompanying ritual includes (1) the application of marks on the forehead, characterizing the adherents of a particular religious community, (2) the presentation of offerings (water, flowers) to the Sun, and (3) meditative concentration.
His minimalist presentation — desk, glass of water, notes — looks to be modeled on the stripped-down style of Spalding Gray.
These results show that the sequence of presentation of quinine and water did not affect performance.
As has previously been observed [14], 68 90% of the food was taken from the trough during presentation of the tap water control, while no food was removed from the treatment troughs.
During the experiments, the bee's response to the presented odorant (PER or no PER) after the onset of the odorant and before the presentation of the sugar water in the case of reinforced trials was recorded.
