Influence of meteorological parameters and air pollution on hourly fluctuation of birch (Betula L.) and ash (Fraxinus L.) airborne pollen.
Pollen grains are one of the most important groups of atmospheric biological particles that originate allergic processes. Knowledge of intradiurnal variation of the atmospheric pollen may be useful for the treatment and prevention of pollen allergies. Intradiurnal fluctuation of hourly pollen counts in 24 h are related to the daily rhythm of anther opening, and modified by various interacting f...
متن کاملGenetic 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 کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Genetic 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 کاملChloroplast 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...
