VX-770 Got You All The Way Down? We Offer The Remedy

This pink background was spotted with 25% of white representing the new flowers. The control trees were built with 75% of green leaf background spotted with 25% of pink flowers. In each chamber arm, the trees were presented against a green background simulating the forest where T. pulchra occurs (Figure ?Figure22). With the visual angle of 3�� we simulated the crown of a T. pulchra tree with 5 m diameter viewed from a distance of 95.5 m. For comparison, a single flower, 5 cm in diameter, can be viewed from a distance of 96 cm under a visual angle of 3��. FIGURE 2 Experimental settings of long-distance experiment (A) and short-distance experiment (B) to test the bee preferences in a Y-maze chamber. We used the same scenario to perform the short-distance experiment VX-770 in vivo with a visual perception angle of 7�� (3 cm diameter flowers at 24.52 cm from the decision point). Four T. pulchra flowers, one white central flower circled by three pink peripheral flowers, were presented against a green background simulating the green leaves. As control we used four identical flowers with 75% pink on the periphery and 25% white on the center (Figure ?Figure22). Thus we kept the same color proportion in the simulation of T. pulchra flowers and in the control treatment. In this setting, we also tested the number of approaches Ribonucleotide reductase to peripheral flowers, because only the central flowers were rewarded with sugar solution in both treatments. We made 12 consecutive trials with 10 naive workers of Bombus terrestris, trained once for each trial learn more in the simulation or in the control and in the left or right side of the Y-maze chamber, totalling 120 approaches in long- and short-distance experiments. Therefore we used the treatment, the training simulation and the training side of the chamber as fixed factors and the bee identity as a random factor in generalized linear mixed-effects models with binomial error distribution. All the statistical tests were performed using the R 2.15.0 software using the packages stats, nlme, and lme4 (http://www.r-project.org/). Results Floral Colors Tibouchina pulchra flowers change their color from white to pink during the 4 days of anthesis (Figure ?Figure33). When we considered the bee-perceivable color spectrum, there was a decrease in the reflection of green and the flowers become more bee-blue (without UV-reflection; Figure ?Figure33). This change was abrupt and occured simultaneously in the tip and the base of the petals. Although there was no difference between the color of the petals�� tip and base (MANOVA, F = 0.75, p = 0.47), the color of flowers of different days was different (MANOVA, F = 20.24, p
