Abstract

The genetic diversity that permits populations to evolve and respond to future stresses and selective pressures is the result of its past evolutionary history. Forces that affected its population size and changes in gene and genotypic frequencies have molded the levels and structure of its genetic variation and hence the future evolutionary capacities of its present populations. Therefore, the genetic diversity is both a cause and an effect of global change and is a measure of the dynamic changes underlying genetic variation that both permits and constrains the future evolution of temperate ecosystems. Neither the global climate nor the genetic variation in ecosystems are independent of the effects of the other, and the history of temperate ecosystems involves the joint evolution of genes and environment.
