Ongoing global warming, coupled with increased drought frequencies, together other biotic drivers may have resulted in complex evolutionary adaptation. The resurrection approach, comparing ancestors raised from stored seeds their contemporary descendants under common conditions, is a powerful method to test for recent evolution plant populations. We used 21-26-yr-old of four European species - Matthiola tricuspidata, Plantago crassifolia, Clinopodium vulgare and Leontodon hispidus seed banks...
Abstract Whereas temporal variability of plant phenology in response to climate change has already been well studied, the spatial is not understood. Given that phenological shifts may affect biotic interactions, there a need investigate how environmental factors relates herbaceous species’ by at same time considering their functional traits predict general and species-specific responses future change. In this project, we analysed records 148 species, which were observed for single year...
Ongoing global warming and increasing drought frequencies impact plant populations potentially drive rapid evolutionary adaptations. Historical comparisons, where plants grown from seeds collected in the past are compared to freshly of same sites, a powerful method investigate recent changes across many taxa. We used 21-38 years old 13 European species, stored seed banks originating Mediterranean temperate regions, together with recently sites for greenhouse experiment shifts flowering...
Phenology of plants is changing rapidly due to global change which may have a large impact on many interactions in ecosystems. So far studies the phenology herbaceous species are largely underrepresented research mainly focused trees and shrubs. In this study we investigated how different phenological stages during annual life cycle differ between they interact with functional traits. To answer these questions, recorded multiple generative vegetative 21 19 tree Botanical Garden Jena 2021. We...
Abstract Rapid environmental changes across Europe include warmer and increasingly variable temperatures, in soil nutrient availability, pollinator decline. These abiotic biotic can affect natural plant populations force them to optimize resource use against competitors. To date, the evolution of competitive ability context availability remains understudied. In this study, we investigated whether common calcareous grassland herb Leontodon hispidus recently evolved its response availability....
Abstract The concept of growing degree days (GDDs) is commonly used to predict phenological events in plants, assuming that plants develop proportionally the accumulated temperature. Two species‐specific parameters, T Base and t 0 (minimum temperature above which start date when GDDs begin accumulate), are considered for calculation. However, optimised thresholds wild herbaceous species remain sparse, therefore reliability models questionable. By employing several modelling approaches using...
Plants must continuously respond to environmental changes, and a timely question is whether how populations ongoing global warming increased drought frequencies intensities. can either through migration or phenotypic plasticity their adapt evolutionarily, which encompasses the evolution of trait means plasticity. One way detect such evolutionary changes within plant historical comparisons where plants grown from seeds collected in past ("ancestors") are compared freshly same ("descendants")...
The world is experiencing increasing climatic variability, an ongoing loss of biodiversity and a growing spread invasive species. Previous experimental studies demonstrated that the invasibility plant populations reduced with resident genetic diversity promoted by environmental fluctuations, but their combined effect has so far not been considered. In growth chamber experiment, we tested whether genotypic Arabidopsis thaliana (1, 3 or 6 genotypes) temperature fluctuations affect population...
Recent climatic changes, such as more frequent droughts and heatwaves, can lead to rapid evolutionary adaptations in plant populations. Such evolution be investigated using the resurrection approach by comparing plants raised from stored ancestral contemporary seeds same population. This has so far only been used common garden experiments, allowing reveal genetic differentiation but not adaptation. In this study, we performed a novel testing for adaptation natural populations study...
Abstract Common-environment experiments are important to study genetically-based phenotypic variation within and among plant populations. Such can be performed in an experimental garden, greenhouse or climate chamber. However, expression may strongly affected by the environmental conditions influenced parental storage effects. Hence, it is unclear if results from common-environment reproducible across multiple setups. In this study, we assessed effects of three different growth facilities –...
Knowing and understanding variation in plant phenology is important for three main reasons. 1. Plant sensitive to climate change, 2. influences the dynamics interactions between species, 3. It drives ecosystem functions. Still, large-scale, macroecological analyses spanning several phenological databases from various continents environmental conditions are scarce. Here we present first results of a global analysis relationship events functional traits herbaceous species as basis predicting...

1. Rapid environmental changes across Europe include warmer and increasingly variable temperatures, in soil nutrient availability pollinator decline. These abiotic biotic can affect natural plant populations by imposing significant selection pressures forcing plants to optimize resource use against competitors. Although recent studies have demonstrated the rapid ongoing evolution of European global change dynamics, competitive ability context remains understudied.2. In this study, we...

Plant populations must continuously adapt to ongoing global climate change, including warmer temperatures and more extreme weather events. One way detect such evolutionary changes within plant is through historical comparisons where plants grown from seeds collected in the past (“ancestors”) are compared freshly same (“descendants”) common garden experiments. Here, we used 21-26 year old stored seed banks for two multi-species experiments that investigated phenotypic traits their plasticity...
