Sex Structure of Scotch Pine Populations in the Dry Steppe

Sex Structure of Scotch Pine Populations in the Dry Steppe it has been determined that the sex structure of the population is of great importance for pine adaptation to extreme environmental conditions. As environmental conditions deteriorate, differentiation of populations with respect to sex becomes more apparent, the proportion of trees of mixed type decreases, and the number of male trees increases. A tendency toward correlation between tree habitus, needle and shoot sizes, and the sex structure of population is noted. The prevalence of male trees in populations exposed to increasing stress reflects the rearrangement of such populations aimed at the more efficient use of natural resources. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Ecology Springer Journals

Abstract

it has been determined that the sex structure of the population is of great importance for pine adaptation to extreme environmental conditions. As environmental conditions deteriorate, differentiation of populations with respect to sex becomes more apparent, the proportion of trees of mixed type decreases, and the number of male trees increases. A tendency toward correlation between tree habitus, needle and shoot sizes, and the sex structure of population is noted. The prevalence of male trees in populations exposed to increasing stress reflects the rearrangement of such populations aimed at the more efficient use of natural resources.
