Data from: Independent effects of host and environment on the diversity of wood-inhabiting fungi

Franz-Sebastian Krah, Sebastian Seibold, Roland Brandl, Petr Baldrian, Jörg Müller & Claus Bässler
1. Dead wood is a habitat for numerous fungal species, many of which are important agents of decomposition. Previous studies suggested that wood-inhabiting fungal communities are affected by climate, availability of dead wood in the surrounding landscape and characteristics of the colonized dead-wood object (e.g. host tree species). These findings indicate that different filters structure fungal communities at different scales, but how these factors individually drive fungal fruiting diversity on dead-wood objects is unknown. 2....

Data from: Phylogeography and evolution of a fungal-insect association on the Tibetan Plateau

Yongjie Zhang, Shu Zhang, Yuling Li, Shaoli Ma, Chengshu Wang, Meichun Xiang, Xin Liu, Zhiqiang An, Jianping Xu & Xingzhong Liu
Parasitoidism refers to a major form of inter-species interactions where parasitoids sterilize and/or kill their hosts typically before hosts reach reproductive age. However, relatively little is known about the evolutionary dynamics of parasitoidism. Here we investigate the spatial patterns of genetic variation of Chinese cordyceps, including both the parasitoidal fungus Ophiocordyceps sinensis and its host insects. We sampled broadly from alpine regions on the Tibetan Plateau and obtained sequences on seven fungal and three insect...

Data from: Limitations of species delimitation based on phylogenetic analyses: a case study in the (Hypogymnia hypotrypa) group (Parmeliaceae, Ascomycota)

Xinli Wei, Bruce McCune, H. Thorsten Lumbsch, Hui Li, Steven Leavitt, Yoshikazu Yamamoto, Svetlana Tchabanenko & Jiangchun Wei
Delimiting species boundaries among closely related lineages often requires a range of independent data sets and analytical approaches. Similar to other organismal groups, robust species circumscriptions in fungi are increasingly investigated within an empirical framework. Here we attempt to delimit species boundaries in a closely related clade of lichen-forming fungi endemic to Asia, the Hypogymnia hypotrypa group (Parmeliaceae). In the current classification, the Hypogymnia hypotrypa group includes two species: H. hypotrypa and H. flavida, which...

Data from: The rpb2 gene represents a viable alternative molecular marker for the analysis of environmental fungal communities

Tomáš Větrovský, Miroslav Kolařík, Lucia Žifčáková, Tomáš Zelenka & Petr Baldrian
Although the commonly used internal transcribed spacer region of rDNA (ITS) is well suited for taxonomic identification of fungi, the information on the relative abundance of taxa and diversity is negatively affected by the multicopy nature of rDNA and the existence of ITS paralogues. Moreover, due to high variability, ITS sequences cannot be used for phylogenetic analyses of unrelated taxa. The part of single-copy gene encoding the second largest subunit of RNA polymerase II (rpb2)...

Data from: Geosmithia associated with bark beetles and woodborers in the western USA: taxonomic diversity and vector specificity

Miroslav Kolařík, Steven J. Seybold, Ned Tisserat, Wilhelm De Beer, David M. Rizzo, Jiri Hulcr & Martin Kostovčík
Fungi in the genus Geosmithia (Ascomycota: Hypocreales) are frequent associates of bark beetles and woodborers that colonize hardwood and coniferous trees. One species, Geosmithia morbida, is an economically damaging invasive species. The authors surveyed the Geosmithia species of California and Colorado, USA, to (i) provide baseline data on taxonomy of Geosmithia and beetle vector specificity across the western USA; (ii) investigate the subcortical beetle fauna for alternative vectors of the invasive G. morbida; and (iii)...

Data from: Unravelling species boundaries in the Aspergillus viridinutans complex (section Fumigati): opportunistic human and animal pathogens capable of interspecific hybridization

Vit Hubka, Vanessa Barrs, Zuzana Dudová, František Sklenář, Alena Kubátová, Tetsuhiro Matsuzawa, Takashi Yaguchi, Yoshikazu Horie, Alena Nováková, Jens C. Frisvad, Jessica Talbot & Miroslav Kolařík
Although Aspergillus fumigatus is the major agent of invasive aspergillosis, an increasing number of infections are caused by its cryptic species, especially A. lentulus and the A. viridinutans species complex (AVSC). Their identification is clinically relevant because of antifungal drug resistance and refractory infections. Species boundaries in the AVSC are unresolved since most species have uniform morphology and produce interspecific hybrids in vitro. Clinical and environmental strains from six continents (n = 110) were characterized...

Data from: Complementarity in both plant and mycorrhizal fungal communities are not necessarily increased by diversity in the other

Cameron Wagg, Christoph Barendregt, Jan Jansa, Marcel G. A. Van Der Heijden & Marcel G.A. Van Der Heijden
1. Higher species diversity can improve community performance within a species guild when different species complement each other in their use of the available niche, such as through resource partitioning. However, species in one guild of organisms may act as resources for another such that the diversity in one guild alters the realized niche for species in another. Yet, it remains largely untested as to whether diversity in one guild of organisms influences species complementarity...

Data from: Do arbuscular mycorrhizal fungi stabilize litter-derived carbon in soil?

Erik Verbruggen, Jan Jansa, Edith C. Hammer & Matthias C. Rillig
1. Fine roots and mycorrhiza often represent the largest input of carbon (C) into soils, and are therefore of primary relevance to the soil C balance. Arbuscular mycorrhizal (AM) fungi have previously been found to increase litter decomposition which may lead to reduced soil C stocks, but these studies have focused on immediate decomposition of relatively high amounts of high-quality litter and may therefore not hold in many ecological settings over longer terms. 2. Here...

Data from: The direction of carbon and nitrogen fluxes between ramets changes during ontogeny under simulated competition for light

Jana Duchoslavová & Jan Jansa
Resource sharing is universal among connected ramets of clonal plants, and is driven both by the developmental status of ramets and resource gradients. Aboveground competition forms spatial light gradients, but the role of resource sharing in such competition is unclear. We examined translocation of resources between mother and daughter ramets of Agrostis stolonifera under light heterogeneity throughout ramet ontogeny. We labelled ramets by 13C and 15N to estimate bidirectional translocation of the resources at three...

Data from: Extraction and separation of active ingredients in Schisandra chinensis (Turcz.) Baill and the study of their antifungal effects

Haijing Yi, Yan Chen, Jun Liu, Jie Zhang, Wei Guo, Weilie Xiao & Yuncong Yao
Schisandra chinensis extracts (SEs) have traditionally been used as an oriental medicine for the treatment of various human diseases, however, their further application in the biocontrol of plant disease remains poorly understood. This study was conducted to develop eco-friendly botanical pesticides from extracts of S. chinensis and assess whether they could play a key role in plant disease defense. Concentrated active fractions (SE-I, SE-II, and SE-III) were obtained from S. chinensis via specific extraction and...

Data from: Pathogen richness and abundance predict patterns of adaptive MHC variation in insular amphibians

Supen Wang, Conghui Liu, Anthony B. Wilson, Na Zhao, Xianping Li, Wei Zhu, Xu Gao, Xuan Liu & Yiming Li
The identification of the factors responsible for genetic variation and differentiation at adaptive loci can provide important insights into the evolutionary process, and is crucial for the effective management of threatened species. We studied the impact of environmental viral richness and abundance on functional diversity and differentiation of the MHC class Ia locus in populations of the black-spotted pond frog (Pelophylax nigromaculatus), an IUCN-listed species, on 24 land-bridge islands of the Zhoushan Archipelago and 3...
