The ranges, spectra of habitat types, and food spectra of artiodactyls in the Far East have been studied. It has been supposed that the overlap of ranges and habitat-type spectra should decrease with an increase in the overlap of food spectra. However, all the three similarity indices have proved to be positively correlated with each other, suggesting that, on the regional scale, the negative role of trophic competition in artiodactyl communities is insignificant, probably because of their low abundance. Conversely, the similarity of food spectra may be regarded as a factor accounting for the overlap of ranges and habitat spectra and, on a large-region scale, for the maintenance of high species diversity.
