Fungal diversity and seasonal succession in ash leaves infected by the invasive ascomycete Hymenoscyphus fraxineus. [PDF]

New Phytol, 2017
Summary High biodiversity is regarded as a barrier against biological invasions. We hypothesized that the invasion success of the pathogenic ascomycete Hymenoscyphus fraxineus threatening common ash in Europe relates to differences in dispersal and colonization success between the invader and the diverse native competitors.

The occurrence of Hymenoscyphus pseudoalbidus apothecia in the leaf litter of Fraxinus excelsior stands with ash dieback symptoms in southern Poland

Acta Mycologica, 2013
The paper presents the results of a study performed in 28 ash stands located in Myśleniece and Dynów Forest Districts in southern Poland. The intensity of Fraxinus excelsior disease process was estimated based on the disease symptoms analysis of 1400 ...

Assessing the exposure of forest habitat types to projected climate change-Implications for Bavarian protected areas. [PDF]

Ecol Evol, 2019
Climate change particularly affects forest ecosystems due to their longevity and slow migration response. Using ensembles of species distribution models, this study analyzed the exposure of forest habitat types from the EU Habitats Directive to projected climate change.

First Report of the Ash Dieback Pathogen Hymenoscyphus pseudoalbidus (Anamorph Chalara fraxinea) on Fraxinus excelsior in Belgium

Plant Disease, 2011
Since the early 1990s, European ash (Fraxinus excelsior L.) has been affected by a lethal disease caused by the ascomycete fungus, Hymenoscyphus pseudoalbidus, originally known under the name of its anamorph, Chalara fraxinea (2,4). Pathogenicity of H. pseudoalbidus was demonstrated by inoculations on young trees (3).

Occurrence of Hymenoscyphus pseudoalbidus on infected ash logs [PDF]

Plant Pathology, 2012
Ash decline induced by Hymenoscyphus pseudoalbidus is an emerging disease that severely affects Fraxinus excelsior stands in Europe. There has been an invasive spread of the disease from east to west in Europe over the last decade. Wood discoloration on

Tree community composition stabilizes ecosystem functions in response to drought

Ecosphere, Volume 14, Issue 4, April 2023., 2023
Abstract In summer 2018, Central Europe was hit by an extreme drought event that widely impacted ecosystems and markedly increased tree mortality in forest ecosystems across the continent. As climate models predict an increase in frequency and severity of such events, there is an urgent need to adapt forests in order to maintain the diverse benefits ...

Application of fungicides and urea for control of ash dieback

iForest - Biogeosciences and Forestry, 2015
Ash dieback is caused by a highly pathogenic fungus Hymenoscyphus pseudoalbidus (anamorph Chalara fraxinea). Possibilities for disease control are limited, and treatment of fallen leaf debris to prevent sporulation of the pathogen is one of the possible ...

Tree diseases determined by the reporting, prognostic and diagnostic service for forests in Slovenia 1982-2012

Acta Silvae et Ligni, 2013
The Reporting, Prognostic and Diagnostic (RPD) service for forests is a legal forest protection organization in Slovenia and part of the public forest service. The aim of our study was to analyse RPD reports from 1982 to 2012.

Susceptibility of autochthonous German Fraxinus excelsior clones to Hymenoscyphus pseudoalbidus is genetically determined [PDF]

Annals of Forest Science, 2014
AbstractContextIt might be possible to establish a new generation of Fraxinus excelsior which is insusceptible towards ash dieback (agent: Hymenoscyphus pseudoalbidus) by efficient breeding. However, a considerable number of highly tolerant individuals which have the ability to pass on this trait to their progeny are needed.AimsThe aim of this study ...

Ultrastructural modifications in Common ash tissues colonised by Chalara fraxinea

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
