Sphagnum magellanicum has been viewed as being a predominantly circumpolar species in the northern hemisphere, but it occurs southern hemisphere and was originally described from parts of Chile. It is an ecologically important mire ecosystems extensively used model to study processes growth, carbon sequestration peat decomposition. Molecular experimental studies have, however, revealed genetic structure within S. magellanicum, morphological differences associated with these groups. Here we...
Abstract Climate change is affecting the composition and functioning of ecosystems across globe. Mountain are particularly sensitive to climate warming since their biota generally limited by low temperatures. Cryptogams such as lichens bryophytes important for biodiversity these ecosystems, but have not often been incorporated in vegetation resurvey studies. Hence, we lack a good understanding how vascular plants, respond interactively alpine communities. Here quantified long‐term changes...
Norway launched a national action plan on wetland restoration in 2016. So far, 90% of the effort has been peatland restoration, with about 140 mires restored so far. There are three main goals stated plan: 1) limit greenhouse gas (GHG) emission, 2) climate adaptation and 3) improved ecological condition. Quantifying outcome actions is necessary to evaluate whether met. A vegetation monitoring protocol was suggested before started implemented at five sites. As increasing, it timely if data...
Most species are assumed to have survived south or east of the ice sheet covering northern Europe during last glacial maximum. Molecular and macrofossil evidence suggests, however, that some may in ice-free areas Scandinavia. In plants, inbreeding vegetative growth associated with low genetic load enhanced survival small, isolated populations. These characteristics often found bryophytes, possibly allowing them survive extreme conditions refugia also within sheets. Here, we review Holocene...
Spore-producing organisms have small dispersal units enabling them to become widespread across continents. However, barriers gene flow and cryptic speciation may exist. The common, haploid peatmoss Sphagnum magellanicum occurs in both the Northern Southern hemisphere, is commonly used as a model studies of peatland ecology physiology. Even though it will likely act rich source functional genomics years come, surprisingly little known about levels genetic variability structuring this species....
Abstract Aim Disjunctly distributed peatmosses ( Sphagnum ) have been found to exhibit little genetic structure over regional and intercontinental scales, mainly caused by high ability for transoceanic long‐distance dispersal. Although, most Northern Hemisphere peatmoss species wide circumboreal/nemoral ranges, is known about the magnitude effects of dispersal barriers in shaping such species. We investigate whether capacity has homogeneity across broad areas Hemisphere, or act shape...
The Society for Ecological Restoration (SER) Primer identifies key ecosystem attributes evaluating restoration outcome. Broad attribute categories could be necessary due to the large variety of projects, but make overall evaluations and assessments challenging might hamper development sound successful restoration. In this study we carry out a systematic review scientific papers addressing evaluation We include 104 studies published after 2010 from Europe or North America, representing...
Human activity is accelerating biodiversity loss despite international commitments to prevent extinction and habitat degradation. To bend the curve, goals must be translated into national targets actions. Tools do this are highly needed, but scarce. We present a first attempt operationalize Red Lists by using quantitative criteria of risk assessment as quantifiable objectives in Green framework. The framework allows for systematic setting conservation goals, with objectives, identifying...
PREMISE OF THE STUDY: Populations with phenotypic polymorphism in discrete characters may be good models for investigating genome evolution and speciation. Sphagnum magellanicum Brid. is found throughout the northern hemisphere, despite considerable variation morphological characters, it considered one of least taxonomically controversial peatmoss species. We have observed two main morphs species associated different microhabitats. Here we investigated genomic environmental basis this...
Climate change has considerably dominated science-policy dialogue, public debate, and subsequently environmental policies since the three "Rio Conventions" were born. This led to practically independent courses of action climate mitigation biodiversity conservation actions, neglecting potential conflicts among outcomes with missed opportunities for synergistic measures. Transformative governance principles have been proposed overcome these limitations. Using a transformative lens, we use...
Peatmosses are interesting for studies of speciation processes not only because their frequent hybridization and recent diversification, but also phenotypic diversity, ecological importance ancient history. Diverse widespread has been widely documented in the genus, little is known about what factors underlie this phenomenon. We hypothesize that these include phylogenetic distance variation life-history traits parental species. summarize current knowledge occurrence peatmosses explore how it...
• Premise of the study: Organisms may survive unfavorable conditions either by moving to more favorable areas means dispersal or adapting stressful environments. Pleistocene glacial periods represent extremely for majority life forms, especially sessile organisms. Many studies have revealed placements refugial and postglacial colonization patterns seed plants, but little is still known about long‐term survival historical migration routes bryophytes. Given overall differences in stress...
Abstract The successful implementation of the Convention on Biological Diversity's post‐2020 Global Biodiversity Framework will rely effective translation targets from global to national level and increased engagement across diverse sectors society. Species conservation require policy support measures that can be applied a diversity taxonomic groups, link action outcome goals, both data sets account for context, which species threat abatement restoration (STAR) metric does. To test...
We describe Sphagnum incundum in subgenus Acutifolia (Sphagnaceae, Bryophyta). used both molecular and morphological methods to the new species. Molecular relationships with closely related species were explored based on microsatellites nuclear plastid DNA sequences. The description is qualitative examination of characters measurements leaves hyalocysts. Morphological are compared between results from Feulgen densitometry microsatellite analysis show that S. gametophytically haploid....
In plants, hybridization between interspecific taxa leading to chromosome doubling seems happen regularly and may be an important driver of speciation. Allopolyploid species often have morphological traits from both parents, broader ecological niches, are hypothesized more common going northwards. About 20% all Sphagnum been inferred allopolyploids. Here we describe the first allotriploid in northern hemisphere, using molecular data, Feulgen densitometry, examination. Our data also supports...
Abstract Loss of biodiversity is accelerating, including the loss genetic diversity. Conservation small, isolated populations may be important, as they can provide valuable contributions to overall variation and long-term viability species. Furthermore, such play an essential role in adaptation new environments following changes e.g. land-use climate. Dracocephalum ruyschiana a threatened plant species throughout its European distribution, but 25% are situated within Norway. Therefore, has...
Conserving species and their genetic variation are a global priority to safeguard evolutionary potential in rapidly changing world. Species fundamental units research nature management, but taxonomic work is increasingly undermined. Increasing knowledge on the diversity would aid prioritizing conservation efforts.
Abstract Questions Analysing how multiple facets of biodiversity vary across space and time can help to predict the vulnerability mountaintop floras future environmental changes. Here we addressed following questions: (a) Are elevational patterns plant diversity consistent taxonomy, function phylogeny? (b) How have taxonomic, functional phylogenetic dimensions communities changed over past two decades? (c) Is magnitude these temporal trends dependent on elevation? Location Dovrefjell,...
