Genetic Characterization of Common ash (Fraxinus excelsior L.) populations in Bosnia and Herzegovina
Background and Purpose: Common ash (Fraxinus excelsior L.) is a species with a widespread distribution in Europe. It mostly grows on mesophyll sites, mainly in karst valleys and by forest creeks, and in Herzegovina at northern expositions and higher altitudes with somewhat better types of soil. Materials and Methods: We studied 10 natural populations. We collected dormant buds with branches fro...
متن کاملDifferential patterns of morphological and molecular hybridization between Fraxinus excelsior L. and Fraxinus angustifolia Vahl (Oleaceae) in eastern and western France.
We examined large-scale patterns of morphology, genetic structure and ecological correlates of Fraxinus excelsior and the closely related species Fraxinus angustifolia in France, in order to determine the degree of hybridization between them. We sampled 24 populations in two putative hybrid zones (Loire and Saône), and five control populations of each species. We measured foliar characteristics...
متن کاملGenetic Structure in the Northern Range Margins of Common Ash, Fraxinus excelsior L.
During post glacial colonization, loss of genetic diversity due to leading edge effects may be attenuated in forest trees because of their prolonged juvenile phase, allowing many migrants to reach the colonizing front before populations become reproductive. The northern range margins of temperate tree taxa in Europe are particularly suitable to study the genetic processes that follow colonizati...
متن کاملRising out of the ashes: additive genetic variation for susceptibility to Hymenoscyphus fraxineus in Fraxinus excelsior
Ash dieback due to Hymenoscyphus fraxineus is threatening the Fraxinus excelsior species in most of its natural range in Europe and it is becoming obvious that other species in the Fraxinus genus are susceptible to the disease. The fungal pathogen apparently originates from Asia where it may act as an endophyte of local species like F. mandshurica. Previous studies reported significant levels o...
متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
