Ecotypes in Graylings (Thymallidae, Salmoniformes)

  • E. A. Zinov'ev
Article

Abstract

The ecotypic structure of two grayling species in Eurasia is considered. Based on original and published data, the development of ecological forms in water bodies of different kinds is analyzed. Parallelism in the emergence of highly similar forms in different sites of the ranges is demonstrated. Distinctive features of ecotypes and their internal structure are described. The causes and rate of establishment of forms with a short life cycle are discussed.
