Abstract: | The thesis of the genetic divergence of Pinus sylvestris L. populations that have spread to bogs from the original dry-land populations has been deduced from the concept of the cyclicity
of helio- and geophysical processes, derivative postulates on climatic cycles, formation of Holocene high bogs, contrasting
differentiation between their environment and that of dry meadows, and the resultant changes in the vectors of microevolutionary
factors and strong reproductive isolation between these populations. Logical genetic, ecological-phenotypical, and geographic
consequences of this theory have been verified by factual data and general laws known to date. The interpolational and predictive
roles of the new theory are demonstrated. |
