The International Tundra Experiment (ITEX) is a collaborative, multisite experiment using common temperature manipulation to examine variability in species response across climatic and geographic gradients of tundra ecosystems. ITEX was designed specifically arctic alpine increased temperature. We compiled from one four years experimental data 13 different sites used meta-analysis analyze responses plant phenology, growth, reproduction warming. Results indicate that key phenological events...
Abstract The dataset presented here was collected by the GenTree project (EU-Horizon 2020), which aims to improve use of forest genetic resources across Europe better understanding how trees adapt their local environment. This individual tree-core characteristics including ring-width series and whole-core wood density for seven ecologically economically important European tree species: silver birch ( Betula pendula ), beech Fagus sylvatica Norway spruce Picea abies black poplar Populus nigra...
Microsatellite markers are widely used for estimating genetic diversity within and differentiation among populations. However, it has rarely been tested whether such estimates useful proxies genome-wide patterns of variation differentiation. Here, we compared microsatellite with single nucleotide polymorphisms (SNPs) to assess quantify potential marker-specific biases derive recommendations future studies. Overall, genotyped 180 Arabidopsis halleri individuals from nine populations using 20...
Abstract Testing how populations are locally adapted and predicting their response to future environment is of key importance in view climate change. Landscape genomics a powerful approach investigate genes environmental factors involved local adaptation. In pooled amplicon sequencing 94 71 populations, we tested whether >3500 single nucleotide polymorphisms ( SNP s) the three most common oak species Switzerland Quercus petraea, Q. pubescens, robur ) show an association with abiotic...
Abstract Genetic monitoring of populations currently attracts interest in the context Convention on Biological Diversity but needs long-term planning and investments. However, genetic diversity has been largely neglected biodiversity monitoring, when addressed, it is treated separately, detached from other conservation issues, such as habitat alteration due to climate change. We report an accounting efforts monitor population Europe (genetic effort, GME), evaluation which can help guide...
Norway spruce (Picea abies [L.] Karst.) is a broadly distributed European conifer tree whose history has been intensively studied by means of fossil records to infer the location full-glacial refugia and main routes postglacial colonization. Here we use recently compiled pollen data as template examine how past demographic events have influenced species' modern genetic diversity. Variation was assessed in mitochondrial nad1 gene containing two minisatellite regions. Among 369 populations...
Abstract Climatic history and ecology are considered the most important factors moulding spatial pattern of genetic diversity. With advent molecular markers, species’ historical fates have been widely explored. However, it has remained speculative what role ecological played in shaping structures within species. an unprecedented, dense large‐scale sampling genome‐screening, we tested how influenced Alpine plants. Here, show that species growing on similar substrate types, largely determined...
A major challenges facing landscape geneticists studying adaptive variation is to include all the environmental variables that might be correlated with allele frequencies across genome. One way of identifying loci are possibly under selection see which ones associated gradient or heterogeneity. Since it difficult measure variables, one may take advantage spatial nature filters incorporate effect unaccounted in analysis. Assuming signature these broad-scaled, broad-scale Moran's eigenvector...
Dispersal is a process critical for the dynamics and persistence of metapopulations, but it difficult to quantify. It has been suggested that old-forest lichen Lobaria pulmonaria limited by insufficient dispersal ability. We analyzed 240 DNA extracts derived from snow samples L. pulmonaria-specific real-time PCR (polymerase chain reaction) assay ITS (internal transcribed spacer) region allowing discrimination among propagules originating single, isolated source tree or other locations....
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...
Understanding the genetic basis of adaptation in response to environmental variation is fundamental as plays a key role extension ecological niches marginal habitats and speciation. Based on assumption that some genomic markers are correlated variables, we aimed detect loci relevance alpine plant Arabis alpina L. sampled two regions, French (99 locations) Swiss (109 Alps. We used an unusually large genome scan [825 amplified fragment length polymorphism (AFLPs)] four variables related...
Abstract Identifying adaptive genetic variation is a challenging task, in particular non‐model species for which genomic information still limited or absent. Here, we studied distribution patterns of amplified fragment length polymorphisms (AFLPs) response to environmental variation, 13 alpine plant consistently sampled across the entire European Alps. Multiple linear regressions were performed between AFLP allele frequencies per site as dependent variables and two categories independent...
Gene flow is a key factor in the evolution of species, influencing effective population size, hybridisation and local adaptation. We analysed gene eight stands white oak (mostly Quercus petraea Q. robur, but also pubescens faginea) distributed across Europe. Adult trees within given area each stand were exhaustively sampled (range [239, 754], mean 423), mapped, acorns collected ([17,147], 51) from several mother ([3], [47], 23). Seedlings ([65,387], 178) harvested geo-referenced six stands....
Conservation genetics is a well-established scientific field. However, limited information transfer between science and practice continues to hamper successful implementation of knowledge in conservation management. To mitigate this challenge, we have established community, which entails an international exchange-and-skills platform related genetic methods approaches First, it allows for exchange researchers during annual conferences. Second, personal contact professionals scientists...
Natural genetic variation is essential for the adaptation of organisms to their local environment and changing environmental conditions. Here, we examine genomewide patterns nucleotide in natural populations outcrossing herb Arabidopsis halleri associations with climatic among Alps. Using a pooled population sequencing (Pool-Seq) approach, discovered more than two million SNPs five identified highly differentiated genomic regions using FST -based analyses. We tested only most strongly...
Abstract The ongoing increase in global temperature affects biodiversity, especially mountain regions where climate change is exacerbated. As sessile, long‐lived organisms, trees are challenged terms of adapting to rapid change. Here, we show that low rates allele frequency shifts Swiss stone pine ( Pinus cembra ) occurring near the treeline result high genomic vulnerability future warming, presumably due species’ long generation time. Using exome sequencing data from adult and juvenile...
The effect of past environmental changes on the demography and genetic diversity natural populations remains a contentious issue has rarely been investigated across multiple, phylogenetically distant species. Here, we perform comparative population genomic analyses demographic inferences for seven widely distributed ecologically contrasting European forest tree species based concerted sampling 164 their ranges. For all species, effective size, N
Abstract Forests are under pressure and going through rapid changes. However, current inventorying monitoring (IM) programs often either disjointed, too narrow in their scope and/or do not operate at fine enough temporal resolutions, which may hinder scientific understanding, the timely supply of information, fast decision making, result sub-optimal use resources. For these reasons, there is an urgent need for Advanced Forest Inventorying Monitoring (AIM) to (i) achieve expanded relevance...
Abies alba is an important European tree species currently mostly found at cool and humid sites in the montane zone. In past, it grew under markedly warmer drier climates during Eemian mid-Holocene, cryptic Mediterranean populations confirm species' capacity to grow warm, summer-dry conditions. However, unknown if warm-loving occurrences are related specific genetic properties (e.g., subspecies or ecotypes). Investigating genetics of crucial for a better understanding past future population...
