High Arctic vegetation after 70 years: a repeated analysis from Svalbard
We asked whether vegetation mapping repeated after 70 years revealed vegetation changes in the high Arctic. The study site is located at 78°38′N, 16°45′E, near Brucebyen at the Adolfbukta Bay (headExpand

Clonal growth forms in Arctic plants and their habitat preferences: a study from Petuniabukta, Spitsbergen
The ability to grow clonally is generally considered important for plants in Arctic regions but analyses of clonal characteristics are lacking for entire plant communities. To fill this gap, weExpand

Partial generic revision of Barbula (Musci: Pottiaceae): Re-establishment of Hydrogonium and Streblotrichum, and the new genus Gymnobarbula
Large genera, that were defined using a restricted suite of morphological characters, are particularly prone to be polyphyletic. We analysed a representative selection of species traditionallyExpand

Fungal root symbionts of high-altitude vascular plants in the Himalayas
Arbuscular mycorrhizal fungi (AMF) and dark septate endophytes (DSE) form symbiotic relationships with plants influencing their productivity, diversity and ecosystem functions. Only a few studies onExpand

Widespread co-occurrence of multiple ploidy levels in fragile ferns (Cystopteris fragilis complex; Cystopteridaceae) probably stems from similar ecology of cytotypes, their efficient dispersal and
BACKGROUND AND AIMS Polyploidy has played an important role in the evolution of ferns. However, the dearth of data on cytotype diversity, cytotype distribution patterns and ecology in ferns isExpand

Two widespread green Neottia species (Orchidaceae) show mycorrhizal preference for Sebacinales in various habitats and ontogenetic stages
Plant dependence on fungal carbon (mycoheterotrophy) evolved repeatedly. In orchids, it is connected with a mycorrhizal shift from rhizoctonia to ectomycorrhizal fungi and a high natural 13C and 15NExpand

Natural hybridization in tropical spikerushes of Eleocharis subgenus Limnochloa (Cyperaceae): Evidence from morphology and DNA markers.
UNLABELLED PREMISE OF THE STUDY Natural hybridization represents an important force driving plant evolution and affecting community structure and functioning. Hybridization may be overlooked,Expand
