Chloroplast DNA variation and postglacial recolonization of common ash (Fraxinus excelsior L.) in Europe.

We used chloroplast polymerase chain reaction-restriction-fragment length polymorphism (PCR-RFLP) and chloroplast microsatellites to assess the structure of genetic variation and postglacial history across the entire natural range of the common ash (Fraxinus excelsior L.), a broad-leaved wind-pollinated and wind-dispersed European forest tree. A low level of polymorphism was observed, with only...

Gene flow of common ash (Fraxinus excelsior L.) in a fragmented landscape

Gene flow dynamics of common ash (Fraxinus excelsior L.) is affected by several human activities in Central Europe, including habitat fragmentation, agroforestry expansion, controlled and uncontrolled transfer of reproductive material, and a recently introduced emerging infectious disease, ash dieback, caused by Hymenoscyphus fraxineus. Habitat fragmentation may alter genetic connectivity and e...

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...

Sex expression and reproductive biology in a tree species, Fraxinus excelsior L.

We investigated Fraxinus excelsior breeding system using field data collected in a natural population and in a seed orchard. First, we attested functional trioecy (co-occurrence of males, hermaphrodites and females), with males producing pollen, hermaphrodites producing both pollen and seeds simultaneously, and females producing seeds. Second, we found that the reproductive system of F. excelsi...

Application of ash (Fraxinus excelsior L.) roots to determine erosion rates in mountain torrents

Due to the effect of global change, the potential risk of natural hazards occurring in alpine areas is expected to increase to an even higher risklevel than has been recorded during the last century. These global changes potentially also have distinct influences on fluvial processes in torrents causing erosion on slopes and riverbanks in forested areas. Dating the time of root exposure along ri...
