Climate change and the ash dieback crisis
Beyond the direct influence of climate change on species distribution and phenology, indirect effects may also arise from perturbations in species interactions. Infectious diseases are strong biotic forces that can precipitate population declines and lead to biodiversity loss. It has been shown in forest ecosystems worldwide that at least 10% of trees are vulnerable to extinction and pathogens ...
متن کاملAsh dieback epidemic in Europe: How can molecular technologies help?
An epidemic of ash dieback disease has spread east to west across Europe, first being noted in Poland in 1992 [1]. The disease is caused by the ascomycete fungus Hymenoscyphus fraxineus (also previously known as Chalara fraxinea and H. pseudoalbidus). This is one of several tree pathogens and insect pests that are recent newcomers to Europe caused by worldwide movements of plants and woody mate...
متن کاملEffects of endophytic fungi on the ash dieback pathogen.
While Hymenoscyphus fraxineus causes dieback of the European ash (Fraxinus excelsior), flowering ash (F. ornus) appears resistant to the pathogen. To date, contributions of endophytic fungi to host resistance are unknown. The following hypotheses were tested: (i) endophytic fungi enhance the resistance of F. excelsior to the pathogen; (ii) resistance of F. ornus relies on its community of endop...
متن کاملCrowdsourced analysis of ash and ash dieback through the Open Ash Dieback project: A year 1 report on datasets and analyses contributed by a self-organising community
Ash dieback is a fungal disease of ash trees caused by Hymenoscyphus pseudoalbidus that has swept across Europe in the last two decades and is a significant threat to the ash population. This emergent pathogen has been relatively poorly studied and little is known about its genetic make-up. In response to the arrival of this dangerous pathogen in the UK we took the unusual step of providing an ...
متن کاملCrowdsourcing genomic analyses of ash and ash dieback – power to the people
Ash dieback is a devastating fungal disease of ash trees that has swept across Europe and recently reached the UK. This emergent pathogen has received little study in the past and its effect threatens to overwhelm the ash population. In response to this we have produced some initial genomics datasets and taken the unusual step of releasing them to the scientific community for analysis without f...
