Transformation of European Ash (Fraxinus excelsior L.) Callus as a Starting Point for Understanding the Molecular Basis of Ash Dieback. [PDF]

open access: yesPlants (Basel), 2021
The population of European ash (Fraxinus excelsior L.) is currently facing the risk of collapse, mainly due to ash dieback, a disease caused by a pathogenic fungus, Hymenoscyphus fraxineus. To facilitate studies into the molecular basis of ash dieback and design breeding strategies for a generation of resistant trees, it is necessary to develop tools ...

A recent ash dieback infection neither affects emerald ash borer performance nor triggers a substantial systemic phytochemical defense response in European ash. [PDF]

open access: yesJ Pest Sci (2004)
The number of non-native invasive species has increased markedly in recent decades, raising the likelihood of co-occurrence and interactions among invaders. Such interactions may exacerbate impacts on native ecosystems, making it essential to understand co-invasion dynamics for effective pest management and conservation.

Young children's perspectives of time: New directions for co‐constructing understandings of quality in ECEC

open access: yesBritish Educational Research Journal, EarlyView., 2023
Abstract Children's relationship with time in preschools is an under‐researched area. Young children rarely know how to measure time using a clock, but their experiences of time may contribute to understanding children's well‐being and debates about quality in preschools.

The radial increment of European ash (Fraxinus excelsior L.) under climate change, Ukraine

open access: yesJournal of Forest Science, 2020
The aim of the study was to compare the response of the radial increment of European ash (Fraxinus excelsior L.) in the Western and Eastern forest steppe of Ukraine to climate change. The growth-climate relationships were estimated for 1961-1987 and 1988-

Mycobiome of Fraxinus excelsior With Different Phenotypic Susceptibility to Ash Dieback

open access: yesFrontiers in Forests and Global Change, 2021
For the last two decades, large-scale population decline of European ash (Fraxinus excelsior) has occurred in Europe because of the introduction of the alien fungal pathogen, Hymenoscyphus fraxineus, from East Asia.

Impact of soil conditioners on the growth of European ash (Fraxinus excelsiorL.) on dumps

open access: yesJournal of Forest Science, 2005
The effects of soil conditioners TerraCottem, Frisol, Bio-algeen and fertilisers Silvamix Forte and Cererit on the survival rate and growth of European ash seedlings until the stage called established plantation were observed on two experimental plots ...
