Fungal Associates of European Bark Beetles With Special Emphasis on the Ophiostomatoid Fungi
- T. Kirisits
Although the association between scolytids and fungi has been recognised for more than one century, many fundamental aspects of this relationship are still poorly understood. Expand
Biogeographical patterns and determinants of invasion by forest pathogens in Europe.
A large database of invasive forest pathogens was developed to investigate the patterns and determinants of invasion in Europe, finding thatEradication seems impossible, and prevention seems the only reliable measure, although this will be difficult in the face of global mobility. Expand
Ash dieback: pathogen spread and diurnal patterns of ascospore dispersal, with special emphasis on Norway.
Dieback of European ash (Fraxinus excelsior), caused by the ascomycete Hymenoscyphus pseudoalbidus (anamorph Chalara fraxinea), started around 1992 in Poland and has since then spread over large… Expand
Phylogenetic relationships between the European and Asian eight spined larch bark beetle populations (Coleoptera, Scolytidae) inferred from DNA sequences and fungal associates
The phylogenetic analysis of beetles used to study the phylogenetic relationships of the eight spined larch bark beetles suggests that the I. cembrae complex contains at least two taxa: I. tournaisiensis infesting larch in Europe and I. subelongatus infestingLarch in Asia. Expand
Population structure of Hymenoscyphus pseudoalbidus and its genetic relationship to Hymenoscyphus albidus
It is concluded that even though the two fungi have a similar habitat and are morphologically virtually identical, they do not share a recent common ancestor. Expand
Identity and phylogenetic relationships of ophiostomatoid fungi associated with invasive and native Tetropium species (Coleoptera: Cerambycidae) in Atlantic Canada.
In 1999, red spruce (Picea rubens Sarg.) trees in a small area of the Halifax Regional Municipality in Nova Scotia, Atlantic Canada, were found to be infested and killed by Tetropium fuscum (Fabr.)… Expand
The current situation of ash dieback caused by Chalara fraxinea in Austria
Two new Ophiostoma species with Sporothrix anamorphs from Austria and Azerbaijan.
The genus Ophiostoma includes numerous species of primarily insect-vectored, wood-staining fungi. Several anamorph genera that differ in their micronematous or macronematous conidiogenous cells have… Expand
Ceratocystis bhutanensis sp. nov., associated with the bark beetle Ips schmutzenhoferi on Picea spinulosa in Bhutan
Based on morphological characteristics, comparisons of DNA sequence data and its unique ecology, the name C. bhutanensis sp. Expand
New host and country records of the Dothistroma needle blight pathogens from Europe and Asia
Morphological examination of selected specimens from different hosts and countries showed that D. septosporum and D. pini overlap in the length of their conidia, while the width is slightly wider in D.pini than in D., indicating that identification of the two Dothistroma species solely based on morphology is virtually impossible.
