Deadwood is an important biodiversity hotspot in forest ecosystems. While saproxylic insects and wood-inhabiting fungi have been studied extensively, little is known about deadwood-inhabiting bacteria. The study we present is among the first to compare bacterial diversity and community structure of deadwood under field conditions. We therefore compared deadwood logs of two temperate forest tree...

eDNA metabarcoding has become a standard method for assessing wood-inhabiting fungi and bacteria, yet determination of dead-wood-inhabiting beetles still relies on time-consuming collection beetle specimens. We thus tested whether species can be identified by sequencing wood in mesocosm experiment that manipulated assemblages. Dead samples were taken at exit holes DNA was extracted analyzed usi...

The laccate (shiny or varnished) Ganoderma contain fungi that are important wood decay fungi of living trees and decomposers of woody debris. They are also an important group of fungi for their degradative enzymes and bioprocessing potential. Laboratory decay microcosms (LDMs) were used to study the relative decay ability of G anoderma curtisii, Ganoderma meredithiae, Ganoderma sessile, and G a...

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 ...

A new genus of Encyrtidae (Hymenoptera: Chalcidoidea), Noyesencyrtus Singh gen. nov. (type species N. brachyoculus Singh sp. nov.), associated with insects inhabiting fruiting bodies of wood-decaying fungi, and two new species, Psyllaephagus kundapurensis Singh sp. nov. and Ooencyrtus hayatii Singh sp. nov., are described from the Western Ghats of Karnataka, India.

Old trees are rare in the landscape, as many of their associated species. Veteranisation is a method by which attempts made to create microhabitats, otherwise found only old trees, younger at an earlier stage than would occur naturally. Here, we analysed early fungal succession 6 y-old veteranisation wounds ca. 100 y living oak trunks DNA-barcoding wood eight sites Sweden and Norway. We hypothe...

Sequential fungal changes that occur on three types of wood are described, namely naturally durable wood, preservative-treated and radiata pine (considered as untreated wood) for above-ground use, during a four-year survey period. The surveys were conducted thrice at 1, 2, 4 years exposure. During the first second exposure, both total isolates species diversity low in each sample, with ascomyce...

Three commercial silicone emulsions with different functional groups i.e., quat-silicone micro-emulsion (<40 nm particle size), amino-silicone macro-emulsion (110 nm), and silicone macro-emulsion with alkylmodified side groups (740 nm) were used to protect wood samples against fungal decay. The addition of the emulsions to an agar growth medium revealed that all three silicone formulations inhi...

Brown rot basidiomycetes initiate wood decay by producing extracellular reactive oxygen species that depolymerize the structural polysaccharides of lignocellulose. Secreted fungal hydroquinones are considered one contributor because they have been shown to reduce Fe(3+), thus generating perhydroxyl radicals and Fe(2+), which subsequently react further to produce biodegradative hydroxyl radicals...
