In mountainous regions, climate warming is expected to shift species' ranges higher altitudes. Evidence for such shifts still mostly from revisitations of historical sites. We present recent (2001 2008) changes in vascular plant species richness observed a standardized monitoring network across Europe's major mountain ranges. Species have moved upslope on average. However, these had opposite effects the summit floras' boreal-temperate regions (+3.9 average) and Mediterranean (-1.4 species),...
Continental-scale assessments of 21st century global impacts climate change on biodiversity have forecasted range contractions for many species. These coarse resolution studies are, however, limited relevance projecting risks to in mountain systems, where pronounced microclimatic variation could allow species persist locally, and are ill-suited assessment species-specific threat particular regions. Here, we assess the 2632 plant across all major European ranges, using high-resolution (ca....
Abstract Current analyses and predictions of spatially explicit patterns processes in ecology most often rely on climate data interpolated from standardized weather stations. This represents long‐term average thermal conditions at coarse spatial resolutions only. Hence, many climate‐forcing factors that operate fine spatiotemporal are overlooked. is particularly important relation to effects observation height (e.g. vegetation, snow soil characteristics) habitats varying their exposure...
Abstract The Convention on Biological Diversity ( CBD ) aims at the conservation of all three levels biodiversity, that is, ecosystems, species and genes. Genetic diversity represents evolutionary potential is important for ecosystem functioning. Unfortunately, genetic in natural populations hardly considered strategies because it difficult to measure has been hypothesised co‐vary with richness. This means richness taken as a surrogate planning, though their relationship not properly...
Abstract Aim In the alpine life zone, plant diversity is strongly determined by local topography and microclimate. We assessed extent to which aspect its relatedness temperature affect species diversity, colonization disappearance of on summits a pan‐European scale. Location Mountain in Europe's zone. Methods Vascular their percentage cover were recorded permanent plots each cardinal direction 123 32 regions across Europe. For subset from 17 regions, resurvey data 6‐year soil series...
Genome skimming has the potential for generating large data sets DNA barcoding and wider biodiversity genomic studies, particularly via assembly annotation of full chloroplast (cpDNA) nuclear ribosomal (nrDNA) sequences. We compare success genome skims 2051 herbarium specimens from Norway/Polar regions with 4604 freshly collected, silica gel dried mainly European Alps Carpathians. Overall, we were able to assemble 67% samples nrDNA cluster 86%. Average insert length, cover cpDNA rDNA...
Abstract The European Alps are highly rich in species, but their future may be threatened by ongoing changes human land use and climate. Here, we reconstructed vegetation, temperature, impact livestock over the past ~12,000 years from Lake Sulsseewli, based on sedimentary ancient plant mammal DNA, pollen, spores, chironomids, microcharcoal. We assembled a highly-complete local DNA reference library (PhyloAlps, 3923 taxa), used this to obtain an exceptionally sed aDNA record of 366 taxa....
The alpine sedge Carex curvula ssp. is a clonal, dominant graminoid found in the European Alps, Carpathians, Pyrenees and some of Balkan Mountains. It late-successional species acidophilous meadows that occurs on sites were covered by ice during last glacial maximum (LGM). By applying amplified fragment length polymorphism (AFLP) fingerprinting chloroplast DNA (cpDNA) sequencing, we attempted to identify recolonization routes followed after retreat. We relied genetic diversity 37 populations...
The paper provides nomenclatural and taxonomic accounts on Tanacetum clusii , a diploid species found in the Eastern Alps, Carpathians, Dinarides, as well comments its current distribution. A careful examination of historic literature showed that combination T. was first proposed by Kerner predates currently used much younger isonym Soják (1871 vs. 1971). One specimen, karyovoucher from WU, is designated here an epitype for illegitimate name Pyrethrum upon which Chrysanthemum basionym based....
ABSTRACT The distributional range of alpine plants experienced dramatic changes during the Quaternary ice ages. These offer many opportunities for studying impact habitat contraction and fragmentation on both species genetic diversity. Here, we examined amplified fragment length polymorphism‐based diversity in sedge Carex curvula All. relation to siliceous European grasslands which is dominant. We found no relationship or even a negative between indices. Local richness was associated with...
The effect of plant species composition on soil microbial communities was studied at the multiregional level. We compared alpine natural grasslands dominated by Carex curvula and anthropogenic subalpine pastures Nardus stricta. conducted paired sampling across Carpathians Alps used Illumina sequencing to reveal molecular diversity microbes. found that bacterial fungal exhibited contrasting regional distributions distribution in each grassland is well discriminated. Beta much higher C. due a...
In the European Alpine System, Carpathian Mountains are recognized as one of major centres diversity and endemism. present study, we aimed to explain spatial structure plant endemism in its South-Eastern subunit by complementary use indices, parsimony analysis endemicity (PAE), biotic element (BEA), barrier analysis. We analyzed available information on 111 taxa confined Carpathians, mapped using two different sets operational geographical units (OGUs): 71 geomorphological 64 quadrats. Our...
This report describes the Romanian Grassland Database (RGD), registered under EU-RO-008 in Global Index of Vegetation-Plot Databases (GIVD).This collaborative initiative aims to collect all available vegetation-plot data (relevés) grasslands and other open habitats from territory Romania provide them for science, nationally internationally, e.g.via European Vegetation Archive (EVA) global database "sPlot".The mainly contains vegetation-plots not only wet, mesic, dry, saline, alpine rocky...
Abstract While climatic research about treeline has a long history, the conditions corresponding to upper limit of closed alpine grasslands remain poorly understood. Here, we propose definition for this limit, ‘grassline’, in analogy treeline, which is based on growing season length and soil temperature. Eighty-seven mountain summits across ten European ranges, covering three biomes (boreal, temperate, Mediterranean), were inventoried as part GLORIA project. Vascular plant cover was...
Low-coverage whole genome shotgun sequencing (or skimming) has emerged as a cost-effective method for acquiring genomic data in nonmodel organisms. This provides sequence information on chloroplast (cpDNA), mitochondrial (mtDNA) and nuclear ribosomal regions (rDNA), which are over-represented within cells. However, numerous bioinformatic challenges remain to accurately rapidly obtain such organisms with complex structures rearrangements, particular mtDNA plants or cpDNA some plant families....
The studies conducted on this topic, upon Dianthus genus, are justified both by its exceptional horticultural importance and the fact that genus has a great phytogeographic importance, because of high rate endemic species comprised in it. Also, many taxa included can be found national European Red Lists. vitro biotechnology successfully accomplish needs for conservation these species. 9 or rare from Romanian Flora were studied. In cultures induced starting seeds caulinar, nodal apical...
Microsatellites are codominant markers that, due to their high polymorphism, a common choice for detecting genetic variability in various organisms, including fungi, plants, and animals. However, the process of developing these is both costly time-consuming. As result, cross-species amplification has become more rapid affordable alternative biological studies. The objective this study was assess applicability 13 SSR markers, originally designed Carex curvula, other 14 species belonging...
