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.

Despite the common assumption your learning abilities regarding animals try modified on the sorts of environment in which they perform, this new decimal ramifications of reading show towards the fitness are nevertheless very nearly not familiar. Here, i measure the learning abilities regarding bumble-bees (Bombus terrestris) out-of numerous colonies inside an enthusiastic ecologically relevant associative reading task less than laboratory requirements, prior to analysis the fresh foraging performance of the same colonies within the industry criteria. We demonstrate that version in learning price certainly one of bumble-bee colonies try really coordinated into the foraging abilities, a strong fitness level, lower than pure conditions.
