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...
Abstract Predicting the structure and dynamics of communities is difficult. Approaches linking functional traits to niche boundaries, species co‐occurrence demography are promising, but have so far had limited success. We hypothesized that predictability in community ecology could be improved by incorporating more accurate measures fine‐scale environmental heterogeneity context‐dependent function traits. tested these hypotheses using long term whole‐community data from an alpine plant...
Abstract Linear landscape elements such as hedgerows and road verges have the potential to mitigate adverse effects of habitat fragmentation climate change on species, for instance, by serving a refuge or improving functional connectivity across landscape. However, so far this hypothesis has not been evaluated at large spatial scales, preventing us from making generalized conclusions about their efficacy implementation in conservation policies. Here, we assessed plant diversity patterns 336...
Abstract Leaf energy balance may influence plant performance and community composition. While biophysical theory can link leaf to many traits environment variables, predicting temperature key driver with incomplete parameterizations remains challenging. Predicting thermal offsets ( δ , T − air difference) or coupling strengths β vs. slope) is We ask: (a) whether environmental gradients predict variation in (absorptance, angle, stomatal distribution, maximum conductance, area, height); (b)...
Abstract Questions Restoring grasslands is of great importance to biodiversity conservation counteract widespread, ongoing losses plant species diversity. Using source populations in remnant habitats and increasing functional connectivity mediated by grazing animals within between can benefit grassland restoration efforts.

Abstract Ploidy level in plants may influence ecological functioning, demography and response to climate change. However, measuring ploidy typically requires intensive cell or molecular methods. We map variation quaking aspen, a dominant North American tree species that can be diploid triploid grows spatially extensive clones. identify the predictors spatial scale of using combination genetic ground‐based airborne remote sensing show leaf spectra canopy both classify aspen by with...
Abstract Understanding the establishment of plant species is important to inform management restored grasslands and preserve biodiversity in ancient grasslands. In grassland communities, can establish from seeds arriving via spatial dispersal, soil seed bank or through vegetative spread nearby source individuals. However, this colonization potential likelihood vary with different land‐use history. We investigated relative importance local recruitment sources, such as dispersal space time...
In recent years, restoration on former grassland sites has been widely encouraged globally, aiming to address the historical loss of 90% ancient species‐rich grasslands, and mitigate associated threat biodiversity. The objective our study was investigate a small‐scale how plant species spontaneously colonize restored grasslands. We inventoried 275 permanent plots twice (in 2019 2021) in grassland, following removal conifer plantation. Species richness vegetation cover surveyed were dependent...
Abstract Questions Predicting when invasive species will affect ecosystem functioning remains problematic, with strong contingency upon both the and recipient community's identities. Adopting a functional trait‐based approach might overcome this context‐dependence. As an early exploration of approach, we used greenhouse experiment seeds plant Impatiens glandulifera to assess potential invasion effects on community trait composition biomass production. Location Three distant European seed...
Abstract The article, Impact of climate change on alpine vegetation mountain summits in Norway.
Individual plants can modify the microenvironment within their spatial neighborhood. However, consequences of modification for demography and species interactions remain unclear at community scale. In a study co‐occurring alpine plants, we 1) determined extent species‐specific microclimate by comparing temperature soil moisture between vegetated non‐vegetated microsites several focal species. We 2) how vital rates (survival, growth, fecundity) all varied in response to aboveground...
