Electrophoresis of soluble feather proteins was used to investigate the controversial taxonomic status of the genus Nicator . Nicator was compared to species in four genera of Pycnonotidae and two sub-families of Laniidae. Electrophoretic similarity values were calculated and then transformed to Nei D distances. Dendrograms were constructed using the Fitch-Margoliash, unweighted pair-group, Farris and modified Farris algorithms. The results clearly show the affinities of Nicator are with Pycnonotidae and not with the Laniidae. The modified Farris tree gave the best fit. Within the Pycnonotidae, our data do not support a close relationship between Pycnonotus and Andropadus , as had been previously suggested. |
