a: mean ± SD of 125 observations; N: only nectar gathering; P: only pollen gathering; NP: nectar as well as pollen gathering; PTE: Pollen transfer efficiency; b: t (p < 0.05) = significant (values tested on the basis of paired t-test); c: F (P< 0.05) = significant (values tested for the visitors of a row); zero values indicate that pollinator behavior was absent. |
