Training Abilities of males and Specialists
Looking at feeder options, i discovered that, separate of coaching method, both men and workers clearly enhanced its possibilities reliability across the span of the education for each colour few made use of ( Fig. dos ).
Throughout the training there was no significant difference in the choice accuracy of males and workers (effect of sex on choice accuracy on the initial and final 10 visits of the sequentially presented colour pairs in the sequence: first colour pair: initial: t112 = 0.51, P = 0.61; final: t110 = 0.04, P = 0.97; second: initial: t97 = 0.65, P = 0.52; final: t93 = 0.95, P = 0.35; third: initial: t89 = ?1.59, P = 0.12; final: t85 = ?0.84, P = 0.41; fourth: initial: t81 = ?0.47, P = 0.64; final: t79 = 0.11, P = 0.91; Fig. 2 ). 7 12.9% (males) and 86.5 13.9% (workers) correct choices (t109 = 0.48, P < 0.63).>

In addition to our analyses based on bees for which the learning speed could be quantified using exponential decay curve fitting with Microcal Origin (OriginLab Corporation), we also found no significant difference between the sexes in the prevalence of learning curves, to which no decay function could be successfully fitted, which was the case for 42 of 178 (males) and 47 of 167 (workers) learning curves (? 2 1 = 0.93, P = 0.33).

We found a significant difference in overall learning speed between the two training sequences (GLM: Wald test = 5.71, df = 1, P = 0.02) associated with asymmetrical learning performances on feeder types with similar colours. For both small-distance colour pairs (yellow-green, CD: 0.061; blue-purple, CD: 0.189) initial choice accuracies were significantly different depending on which of the two colours in the pair was rewarded. The choice accuracies on green rewarding and yellow nonrewarding feeders was significantly lower for the first 30 visits than those achieved on the reverse challenge (10 visits: tninety-five = 3.48, P < 0.001;>91 = 2.45, P = 0.02; 30 visits: t91 = 4.67, P < 0.001).>105 = 2.08, P = 0.04; 20 visits: t105 = 2.45, P = 0.02). In both cases these differences diminished as training progressed (green-yellow: 40 visits: tninety = 1.83, P = 0.07; 50 visits: t88 = 1.47, P = do open relationships work 0.14; blue-purple: 30 visits: t104 = 1.55, P = 0.12; 40 visits: t104 = 0.81, P = 0.42; 50 visits: t102 = 0.34, P = 0.74). No significant asymmetries in choice accuracy were found for the two colour pairs consisting of highly different colours (purple-green, blue-yellow). This effect, however, was not affected by sex and was similarly seen in males and workers (GLM: seq?sex: Wald test = 0.66, df = 1, P = 0.42). The differences also did not extend to the latency to switch (GLM: sex: Wald test = 0.67, df = 1, P = 0.41; seq?sex: Wald test = 0.32, df = 1, P = 0.57).
