High Arctic vegetation after 70 years: a repeated analysis from Svalbard
The finding that vegetation mapping repeated after 70 years revealed no changes in vegetation can be interpreted as evidence of a slow ecological response of constituent plants in such a harsh environment and geographic isolation may limit establishment and expansion of new species. Expand
Clonal growth forms in Arctic plants and their habitat preferences: a study from Petuniabukta, Spitsbergen
The overall proportion of clonal plants in the flora of the Petuniabukta region was comparable to that of central Europe, but the flora in the Petunia− bukta region had fewer types ofClonal growth organs, a slower rate of lateral spread, and a different proportion of the two types of rhizomes.

Partial generic revision of Barbula (Musci: Pottiaceae): Re-establishment of Hydrogonium and Streblotrichum, and the new genus Gymnobarbula
A representative selection of species traditionally assigned to the genus Barbula is analysed, believed to represent the largest genus of the moss family Pottiaceae, but which recently was suggested to be polyphyletic. Expand
The oldest sequenced fungal herbarium sample
This study assesses PCR amplification and sequencing of ITS regions (rDNA) from herbarium samples of lichens up to 151 years old; a collection from 1859 sequenced in 2010. Expand

What do Holocene sediments in Petuniabukta, Spitsbergen reveal?
Studies of past vegetation from the inner fjords of the Svalbard archipelago have not previously been reported. This study assesses the potential of sediments retrieved from two sites inExpand
Two widespread green Neottia species (Orchidaceae) show mycorrhizal preference for Sebacinales in various habitats and ontogenetic stages
This study covered 41 European sites, including different meadow and forest habitats and orchid developmental stages, and showed that both Neottia species associated mainly with nonectomycorrhizal Sebacinales Clade B, a group of rhizoctonia symbionts of green orchids, regardless of the habitat or growth stage.

Fungal root symbionts of high-altitude vascular plants in the Himalayas
It is found that mid-elevation steppe and alpine plants hosted more diverse AMF communities than plants from deserts and the subnival zone, and AMF diversity was unimodally related to elevation and positively related to the intensity of AMF colonization. Expand
A case study of intragenomic ITS variation in bryophytes: Assessment of gene flow and role of polyploidy in the origin of European taxa of the Tortula muralis (Musci: Pottiaceae) complex
Interestingly, the pattern of ITS variation together with morphological evidence indicate the autopolyploid origin of some lineages, which renders the T. muralis complex the first group of mosses in which autopolyPLoidy is implied by molecular markers. Expand
Natural hybridization in tropical spikerushes of Eleocharis subgenus Limnochloa (Cyperaceae): Evidence from morphology and DNA markers.
Simultaneous use of various types of molecular markers can overcome many pitfalls of investigations concerning hybridization among closely related and morphologically similar species. Expand
