Comparative studies on the durability of English oak (Quercus robur L.) under in-service, field and laboratory conditions
2017 - IRG/WP 17-10881
The durability of many wood species varies due to differences in extractive content, anatomical features, growth conditions, and not at least in dependence of the respective exposure conditions either under test or in real life applications. And so does the durability of English oak (Quercus robur L.), which has recently been considered in the revised European standard EN 350 (2016) and is now cla...

Genetic characterisation of the deathwatch beetle – Call for support
2017 - IRG/WP 17-10890
The deathwatch beetle (Xestobium rufovillosum) is one of the most important pests of historical wood constructions. Further analysis of the exact nature of the feeding habits regarding diet and wood characteristics might deliver answers for controlling this pest. Also there is little known about genetic variability and population structure within the species. For analysis of infested wood and also...

Imports of African logs, do they harbor wood-decaying alien fungi and bacteria that could become a potential threat at temperate latitudes? – First results
2018 - IRG/WP 18-10904
In this project we investigate the potential threat of alien wood-decaying fungal and bacterial species imported to Germany with logs from African countries. In a first approach we analysed fungal species on imported logs by identification of fruit bodies by DNA sequencing of the internal transcribed spacer (ITS) regions ITS1 and ITS2. First results revealed the existence of at least one alien fun...
