The longitude variation of some ecological physiological features in buntings passeriformes emberizidae

, : The longitude variation of some ecological physiological features in buntings passeriformes emberizidae. Zoologicheskii Zhurnal 63(10): 1547-1554

In the most studied buntings, the clines of relative growth rate, growth constants, relative intensity of singing, numbers and diel rhythms of singing are directed from the east to the west, i.e., begin with the territory characterized by the greatest diversity of species of this family. The location of the center of speciation can be judged, thus, not only by changes in the abundance of related species occurring here, but also by the direction of changes in every feature considered. This is confirmed also by the coincidence of the clines with the direction of unusual migrational routes indicating, as is customary to assume, to the peculiarities of the species distribution and with known current direction of the species migration. The species of buntings which represent by their ranges the western or eastern forms face each other with the clines opposite in direction, thus suggesting the existence of another center of speciation originating in the periphery of the ranges of the species penetrated far from the east to the west.
