Summary We studied the evolutionary history of Parmeliaceae (Lecanoromycetes, Ascomycota), one largest families lichen‐forming fungi with complex and variable morphologies, also including several lichenicolous fungi. assembled a six‐locus data set nuclear, mitochondrial low‐copy protein‐coding genes from 293 operational taxonomic units ( OTU s). The lifestyle originated independently three times in lichenized ancestors within Parmeliaceae, new generic name is introduced for these In all...
Abstract A comparative review of 57 Lepraria species and 2 varieties is provided together with descriptions a key. Lecanora leuckertiana transferred to Lepraria. In addition some putative taxa by different authors are discussed.
The importance of single-species forest plantations in sustaining biodiversity could be bigger than expected. We described the diversity lichens and bryophytes 15 midterm (16- to 17-year-old) hybrid aspen (Populus tremula × Populus tremuloides) Estonia. Species richness composition data were linked with environmental landscape-scale variables. Altogether, 44 lichen 37 bryophyte species recorded from plantations; richnesses positively correlated. Lichen was significantly affected by...
The loss of ancient forests threatens many species. Effective nature conservation needs information on how forest availability in the surrounding landscape space and time determines diversity multiple taxa. We explored relationship between at different spatiotemporal scales various groups: vascular plants (woody species, ground layer), epiphytes (bryophytes lichens), fungi (ectomycorrhizal, arbuscular mycorrhizal, pathogenic, saprotrophic), carabid beetles. Besides observed diversity, we...
Abstract Fourteen genera belong to a monophyletic core of cetrarioid lichens, Ahtiana, Allocetraria, Arctocetraria, Cetraria, Cetrariella, Cetreliopsis, Flavocetraria, Kaernefeltia, Masonhalea, Nephromopsis, Tuckermanella, Tuckermannopsis, Usnocetraria and Vulpicida . A total 71 samples representing 65 species (of 90 worldwide) all type the are included in phylogentic analyses based on complete ITS matrix incomplete sets group I intron, β-tubulin, GAPDH mtSSU sequences. Eleven study analysed...
• Premise of the study: Species boundaries in many organism groups are still a state flux, and for empirical species delimitation, finding appropriate character sets analytical tools among greatest challenges. In lichenized fungal genus Vulpicida , six morphologically circumscribed have been distinguished, but phenotypic characters partly overlap three these intermediate forms occur. We used combination phylogenetic strategies to delimit this genus. Methods: Five DNA loci were sequenced...
Ecosystem biomass, soil conditions and the diversity of different taxa are often interrelated. These relationships could originate from biogeographic affinity (varying species pools) or direct ecological effects within local communities. Disentangling regional causes is challenging as former might mask latter in natural ecosystems with varying habitat conditions. However, when pool contribution considered statistics, be detected. In this study we disentangle indirect on complex among wood...
Abstract This study focuses on European Usnea species with sorediate shrubby thalli, the aim to evaluate morphological and chemical separation of in light molecular data. Twenty-two species, including widely distributed taxa such as U. diplotypus, fulvoreagens, glabrescens, lapponica, subfloridana, substerilis wasmuthii , were included using Bayesian maximum parsimony analyses nuclear ITS beta-tubulin sequences. The showed that: 1) most that are morphologically well delimited also distinct...
The third, updated electronic version of the world list cetrarioid lichens (http://esamba.bo.bg.ut.ee/checklist/cetrarioid/home.php) contains more than 570 names representing 149 accepted species. It is based on a FileMaker powered database, allowing users to view data in different sets and perform searches. presents new information about phylogenetic status taxa, type materials for most names. A concise displayed below includes all currently 25 genera species which are now or have earlier...
Abstract The delimitation of two morphologically similar and not easily separable Vulpicida species, V. juniperinus tubulosus , is analyzed using nuclear ITS Mcm7, mitochondrial SSU DNA sequences. Seventy-nine specimens, most from the focal taxa, are included in three-locus gene tree. results Bayesian parsimony analyses presented. There strong conflicts between single locus trees. divided into clearly distinguished groups concatenated B/MCMC However, these species mixed both clades,...
At the present time 135 cetrarioid lichen species can be listed. According to recent revisionary work they are placed into 22 genera. Six new genera (Arctocetraria, Cetrariella, Flavocetraria, Kaernefeltia, Nimisia and Tuckneraria) have been separated since 1993 when first world list of lichens was presented. The genus Cetrariopsis is included in Nephromopsis this paper. An alphabetical all epithets that applied given, generic name which assigned indicated brackets. author(s) each...
Abstract Two hundred and three specimens belonging to the genus Cetrelia from Soviet Union also 41 samples other countries have been analysed by TLC. Eight species were determined in Union. In addition two new species, C. orientalis pseudocollata sp. nov. are described. Five morphotypes six chemotypes recognized genus: their main characteristics tabulated a form that can be used for identification key is included. Evolutionary relationships between ‘primary’ ‘secondary’ related...
Abstract Questions Abandonment of agricultural land followed by tree planting or natural regeneration has increased forest area in Europe. We asked how restoration approach, past use, site and landscape variables affected the richness composition vascular plants (field shrub layers), bryophytes lichens middle‐aged forests. Location Thirty‐three birch stands Estonia. Methods Data were collected from on former that originated plantations (PL‐A) (NR‐A), for reference, native (NR‐F). In every...
Less intensive harvesting methods (e.g., selection cutting, shelterwood cuttings) are recommended as alternatives to clearcutting for maintaining mature forest biodiversity in the process of regeneration. However, long-term impact low-intensity has rarely been studied. Our aim was clarify effects repeated selective thinning, and cutting on richness, abundance, species composition vascular plants, bryophytes, lichens Scots pine forests (Pinus sylvestris L.). Data were collected from 25 stands...
