Ambrosia symbiosis is an obligate, farming-like mutualism between wood-boring beetles and fungi. It evolved at least 11 times and includes many notorious invasive pests. All ambrosia beetles studied to date cultivate ascomycotan fungi: early colonizers of recently killed trees with poor wood digestion. Beetles in the widespread genus Ambrosiodmus, however, colonize decayed wood. We characterize...

Wood in outdoor applications is exposed to various decay factors, of which fungi are the most important. Some wood species more resistant fungal than others. Forma Viva Kostanjevica has been exhibiting sculptures made mainly oak for 60 years. The oldest sculpture work Tanaka Eisaku entitled “Japanese Festival”. After years, condition was examined with a resistograph and moisture metre. Several ...

Wood in outdoor applications is exposed to abiotic and biotic factors. If we want slow down the decay, wood must be protected. In past, biocidal products based on copper, chromium, boron compounds (CCB) were one of most important solutions for protection under extreme conditions. Although CCB practice no longer used EU, it can serve as a reference evaluation new products. At field test site Dep...

The role of ions in the fungal decay process of lignocellulose biomaterials, and more broadly fungal metabolism, has implications for diverse research disciplines ranging from plant pathology and forest ecology, to carbon sequestration. Despite the importance of ions in fungal decay mechanisms, the spatial distribution and quantification of ions in lignocellulosic cell walls and fungal hyphae d...

This study examined the impact of logs and stumps on the understory composition of 28-yearold aspen-dominated boreal forests. Suitable logs covered more than five times the area of stumps in both harvest and wildfire stands. Logs and stumps were colonized by a significantly different assemblage of vascular plants than the forest floor. Initial colonization patterns on dead wood in both wildfire...

Decayed-wood samples were collected from a naturally-infected bridge made of Quercus robur. Fruiting bodies of the white-rot basidiomycetes Hymenochaete rubiginosa and Stereum hirsutum were sampled. The white-rot fungus Fuscoporia ferrea and the secondary saprobiont Mycena galericulata were identified from the rotten wood by means of rDNA-ITS sequencing. The topochemistry of lignin degradation ...

Chemical modification as a non-biocidal treatment is an effective method to improve physical and biological properties of wood. Poplar fast growing species but has poor dimensional stability durability in addition low mechanical properties. Low molecular weight Dimethylol dihydroxyethyleneurea (mDMDHEU) was used the poplar mainly decay resistance. Results indicated high anti-swelling efficiency...

Fungal laccase can be detected with the nonautooxidizable laccase­ specific compound, syringaldazine, in the presence of tyrosinase and per­ oxidase. Data are presented from tests with the azine derivative of numerous fungous sporophores and associated decayed wood tissues from various localities in Wisconsin and Oregon. Syringaldazine is shown to be a reliable replacement and more specific rea...

Deadwood is involved in several important ecological roles, being the fundamental habitat of wood-decay fungi. At same time, this polyphyletic group fungi principal agent wood decomposition, regulating carbon cycle and food resource for many other organisms. It known that diversity community composition are related to tree species, decay stage size woody debris which they living. Nevertheless, ...
