Host−Pathogen Interactions in Leaf Petioles of Common Ash and Manchurian Ash Infected with Hymenoscyphus fraxineus [PDF]

Microorganisms, 2022
Some common ash trees (Fraxinus excelsior) show tolerance towards shoot dieback caused by the invasive ascomycete Hymenoscyphus fraxineus. Leaf petioles are considered to serve as a pathogen colonization route to the shoots.

Genetic structure in the northern range margins of common ash, Fraxinus excelsior L. [PDF]

PLoS ONE, 2016
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 ...

Mother trees of common ash (Fraxinus excelsior) disperse different sets of mycobiome through their seed wings [PDF]

BMC Research Notes
Objective The endophytic mycobiome is present in all studied plant compartments, including fruits and seeds. Here, we studied the mycobiome of seed wings as they are transferred with seeds in common ash and tested whether the mycobiome differs among ...

Ultrastructural modifications in Common ash tissues colonised by Chalara fraxinea [PDF]

Phytopathologia Mediterranea, 2012
Chalara fraxinea, the cause of ash dieback, is present in many European countries and constitutes a severe threat to Fraxinus spp. in forests, urban areas and nurseries. This study investigated tissue colonisation strategies of the parasite in Common ash

The significance of volcanic ash in Greenland ice cores during the Common Era [PDF]

Quaternary Science Reviews, 2023
Polar ice cores provide long, continuous and well-dated records of past volcanism and have contributed significantly to our understanding of volcanic impacts on climate and society. Sulphate aerosols deposited in the ice are essential for determining the

Potential alternative tree species to Fraxinus excelsior in European forests

Frontiers in Forests and Global Change, 2023
Common ash (Fraxinus excelsior L.) is a keystone tree species in Europe. However, since the 1990s, this species has been experiencing widespread decline and mortality due to ash dieback [Hymenoscyphus fraxineus (T.

Reactivity of Ground Coal Bottom Ash to Be Used in Portland Cement

J, 2021
Ground coal bottom ash is considered a novel material when used in common cement production as a blended cement. This new application must be evaluated by means of the study of its pozzolanic properties.
