摘要:Abstract(#br) Background(#br)Knowledge of the historical distribution and postglacial phylogeography and evolution of a species is important to better understand its current distribution and population structure and potential fate in the future, especially under climate chan...

摘要:Abstract(#br)Understanding the genetic impacts of forest management practices is crucial for conservation and management of forest genetic resources. Forest management practices based on selective and clear cut systems followed by natural or artificial regeneration can impac...

摘要:The allelic constitution of 169 Populus deltoides Marsh, clones, selected in North America, was studied at 8 marker allozyme loci (Aco-2, Mdh-2, Pgi-2, Pgm-1, Pgm-3, 6-Pgd-2, 6-Pgd-4 and 6-Pgd-5) coding for 5 enzyme systems in root tips. The enzymes were assayed by horizontal sta...

摘要:Abstract(#br)Forest harvesting of increasing intensities is expected to have intensifying impacts on the genetic diversity and population structure of postharvest naturally regenerated stands by affecting the magnitude of evolutionary processes, such as genetic drift, gene f...

摘要:Summary(#br)Horizontal starch gel electrophoresis was done to assay 10 enzyme systems in root tips of 14 Populus deltoides x P. nigra clones developed by controlled hybridization and selected in North America, and some clones sharing one or both parents. The genotypes of the clon...

摘要:Summary(#br)Methods of horizontal starch gel electrophoresis of enzymes in root tips of Populus nigra were developed. The genetic structure of 43 P. nigra clones representing selections, cultivars and botanical varieties from 9 European countries was determined for 36 allozyme lo...

摘要:Abstract(#br)Increased use of forest resources and a shrinking forestland base threaten the sustainability of forest genetic resources and highlight the importance of conservation and sustainable management of these resources. As forest trees are normally the keystone species of ...

摘要:Abstract(#br)Forest harvesting and renewal practices using clearcut harvesting followed by artificial and natural regeneration (NR) may impact genetic diversity in subsequent forest tree populations. Plantations (PL) and phenotypic selections may exhibit lower genetic diversity t...

摘要:Abstract(#br)One of the most important drivers of local adaptation for forest trees is climate. Coupled to these patterns, however, are human‐induced disturbances through habitat modification and pollution. The confounded effects of climate and disturbance have rarely been i...

摘要:• Premise of the study: Geographically peripheral (marginal) populations are expected to have lower genetic diversity and higher genetic differentiation than geographically core (central) populations as a result of supposedly lower effective population size ( N e)...
