The fresh correlation from learning rates and you may sheer foraging success for the bumble-bees
Average learning performance shown by individual bees from the 12 test colonies. In each panel (a-l) we present the mean learning performance averaged across bees tested in each colony (D11-D22). Data points (filled diamonds) represent the mean (1 s.e.m.) number of errors made during each consecutive group of flower choices. The starting point (i.e. number of flower choices=0) was calculated from all bees which made at least five choices before feeding from (probing) a yellow (rewarding) flower for the first time. Subsequent data points each represent the mean number of errors (blue flowers chosen) during a series of 10 flower choices averaged across 1215 bees per colony. All bees (n=172) performed at least 100 flower choices. The curves shown in each figure panel indicate the mean learning curve for each colony. The colony learning curve is based on the mean curve parameters (y0, A and t) produced from fitting exponential decay functions (y=y0+Ae ?x/t ) to the flower choice data for each individual bee and averaging parameter values across bees.
Abstract
In spite of the prevalent presumption your discovering performance away from animals try adapted on form of surroundings where it jobs, this new quantitative effects of learning show into the fitness are nevertheless almost unfamiliar. Right here, we measure the training performance away from bumble-bees (Bombus terrestris) off multiple colonies when you look at the an enthusiastic environmentally associated associative understanding activity less than lab criteria, before analysis the newest foraging show of the identical territories under the industry conditions.
