Fungi play vital roles in the decomposition of deadwood due to their secretion various enzymes that break down plant cell-wall complexes. The compositions wood-inhabiting fungal (WIF) communities change over course process as remaining mass wood decreases and both abiotic biotic conditions significantly change. It is currently not resolved which substrate-related factors govern these changes WIF whether such influence rate. Here we report a study on richness community structure Norway spruce...
Nitrogen availability in dead wood is highly restricted and associations with N-fixing bacteria are thought to enable wood-decaying fungi meet their nitrogen requirements for vegetative generative growth. We assessed the diversity of nifH (dinitrogenase reductase) genes common temperate tree species Fagus sylvatica Picea abies from differently managed forest plots Germany using molecular tools. By incorporating these into a large compilation published sequences subsequent phylogenetic...
Abstract Deadwood is an important biodiversity hotspot in forest ecosystems. While saproxylic insects and wood-inhabiting fungi have been studied extensively, little known about deadwood-inhabiting bacteria. The study we present among the first to compare bacterial diversity community structure of deadwood under field conditions. We therefore compared logs two temperate tree species Fagus sylvatica Picea abies using 16S rDNA pyrosequencing identify changes at different stages decay plots...
An active and diverse soil biota is important for maintaining crop productivity quality, preservation of these traits a major goal sustainable farming. This study aimed at unravelling the impact different management practices on fungal bacterial biodiversity in vineyards as model permanent crops. Species diversity was assessed using an amplicon sequencing approach long-term field experiment Rheingau wine region Germany where integrated, organic biodynamic had been place 10 years. Fungal...
Fungi are prominent drivers of ecological processes in soils, so that fungal communities across different soil ecosystems have been well investigated. However, for arable soils taxonomically resolved fine-scale studies including vertical itemization still missing. Here, we combined a cloning/Sanger sequencing approach the ITS/LSU region as marker general fungi and partial SSU arbuscular mycorrhizal (AMF) to characterize microbiome maize habitats. Four compartments were analyzed over two...
Deadwood is an important structural component in forest ecosystems and plays a significant role global carbon nutrient cycling. Relatively little known about the formation decomposition of CWD by microbial communities situ factors controlling associated processes. In this study, we intensively analyzed molecular fungal community composition species richness relation to extracellular enzyme activity differences decomposing sapwood heartwood 13 temperate tree (four coniferous nine deciduous...
Summary Deadwood represents an important structural component of forest ecosystems, where it provides diverse niches for saproxylic biota. Although wood‐inhabiting prokaryotes are involved in its degradation, knowledge about their diversity and the drivers community structure is scarce. To explore effect deadwood substrate on microbial distribution, present study focuses communities logs from 13 different tree species investigated using amplicon based deep‐sequencing analysis. Sapwood...
Despite the important role of wood-inhabiting fungi (WIF) in deadwood decomposition, our knowledge factors shaping dynamics their species richness and community composition is scarce. This due to limitations regarding resolution classical methods used for characterizing WIF communities a lack well-replicated long-term experiments with sufficient numbers tree species. Here, we large scale experiment logs 11 at an early stage distributed across three regions Germany, identify Operational...
Wood-inhabiting fungi are major agents of wood decomposition. However, it is unclear which factors determine their distribution and enzyme production. Many studies that have addressed this issue suffer from a lack geographic extent. Here, we investigate the fungal community structure 117 Fagus sylvatica logs in relation to physico-chemical properties secreted ligninolytic enzymes, across three distinct geographical regions Germany. Our results revealed was similar different regions, but...
Abstract The genus Agrilus is one of the most diverse insect genera worldwide. larval feeding activity causes extensive damage in both forests and orchards. In addition, more than 30 species have been introduced outside their native range so far, including emerald ash borer planipennis Fairmaire. Thus, availability efficient trapping protocols for early detection at entry points utmost importance. this study we tested whether developed surveillance A. North America were also effective other...
Bark protects living trees against environmental influences but may promote wood decomposition by fungi and bacteria after tree death. However, the mechanisms which bark determines assembly process biodiversity of decomposers remain unknown. Therefore, we partially or completely removed from experimentally felled tested with null modelling whether processes were determined coverage if molecularly sampled generally benefited increasing cover. The community composition fungi, wood-decaying...
Lignin and its degradation, particularly in forest ecosystems, play a major role the global carbon cycle. Filamentous fungi equipped with extracellular oxidoreductases (oxidative enzymes), i.e., laccase, manganese-dependent peroxidases several other peroxidases, are key players bioconversion of lignin. In particular, for coarse woody debris (CWD), this process is poorly understood activities laccase have never been studied on large field scale. We investigated these enzymes 701 samples Fagus...
Decaying wood hosts a large diversity of seldom investigated protists. Environmental sequencing offers novel insights into communities, but has rarely been applied to saproxylic We the bright-spored wood-inhabiting Myxomycetes by environmental sequencing. have complex life cycle culminating in formation mainly macroscopic fruiting bodies, highly variable shape and colour that are often found on decaying logs. Our hypothesis was would increase with decay. DNA extracted from chips collected 17...
Summary Nitrogen deposition can strongly affect biodiversity, but its specific effects on terrestrial microbial communities and their roles for ecosystem functions processes are still unclear. Here, we investigated the impacts of N wood‐inhabiting fungi (WIF) related ecological in a highly N‐limited deadwood habitat. Based high‐throughput sequencing, enzymatic activity assay measurements wood decomposition rates, show that addition has no significant effect overall WIF community composition...
