Habitat loss, reduced plant population sizes, and climate change have raised concerns about the impact of these factors on morph ratios and the related consequences on fitness of heterostylous species. We studied the deviation of floral morphs of P. veris from isoplethy (i.e. equal frequency) in response to plant population size, landscape context and climatic factors, based on a pan‐European citizen science campaign involving observations from 28 countries. In addition, we examined the relative frequency of morphs to determine whether landscape and climatic factors disrupt morph frequencies or whether a specific morph has an advantage over the other. Theory predicts equal frequencies of short‐styled S‐morphs and long‐styled L‐morphs in populations at equilibrium. However, data from >3000 populations showed a substantial morph deviation from isoplethy and a significant excess of S‐morphs (9% higher compared to L‐morphs). Deviation of morph frequency from equilibrium was substantially stronger in smaller populations and was not affected by morph identity. Higher summer precipitation and land use intensity were associated with an increased prevalence of S‐morphs. Five populations containing individuals exhibiting short homostyle phenotypes (with the style and anthers in low positions) were found. Genotyping of the individuals at CYP734A50 gene of the S locus, which determines the length of the style and the position of anthers of P. veris , revealed no mutations in this region. Our results based on an unprecedented geographic sampling suggest that changes in land use and climate may be responsible for non‐equilibrium morph frequencies. This large‐scale citizen science initiative sets foundations for future studies to clarify whether the unexpected excess of S‐morphs is due to partial intra‐morph compatibility, disruption of heterostyly or survival advantage of S‐morphs. Synthesis . Human‐induced environmental change may affect biodiversity indirectly through altering reproductive traits, which can also lead to reduced fitness and genetic diversity. Further research should consider the possible role of pollinators in mediating the ecological and evolutionary consequences of recent landscape and climatic shifts on plant reproductive traits.

Previous studies suggested an influence of vertical vegetation structure on habitat use, while the role of horizontal vegetation structure is still poorly understood. In the present study, we used vegetation survey data to investigate the effects of variables related to the horizontal structure and functional composition of vegetation on the occupancy and density of the Hungarian meadow viper. During a spring survey period, we collected viper occurrence data in 59 sampling quadrats alongside plant community samples, then used single‐season occupancy models and N‐mixture models for analysis. After model selection, the best models included the moisture‐related vegetation gradient, species richness, graminoid‐forb ratio, and height of plants as explanatory variables for both occupancy and density. Wetter meadows with fewer plant species, a higher graminoid/forb ratio, and habitats with characteristically lower‐growing plant species were more probable to be used by the vipers. Our results suggest that the horizontal structure of the vegetation influences the habitat use of vipers and also draw attention to the threats posed by more frequent droughts and heatwaves.

Although communication is a core component in citizen science, the key factors that determine its effectiveness in national and transboundary campaigns aimed at broad audiences have remained unclear. Using the pan‐European citizen science campaign ‘Looking for Cowslips’ spanning across 31 European countries as an example, we explored the main communication facilitators and barriers campaign organisers face in different European regions when engaging the public in citizen science. To do so, we conducted interviews, questionnaires and discussion groups with the campaign organisers. The results indicate that communication in citizen science initiatives poses a challenge, particularly for researchers, who often do not have sufficient time or means for the necessary engagement and communication efforts. In addition to the ecological characteristics of the focal species in the different regions of Europe, the key aspects that need to be considered for planning effective communication in transboundary citizen science projects include various socio‐cultural factors, such as the traditions related to citizen science in different countries as well as local indigenous knowledge. Our study shows that collaboration between academic institutions and environmental non‐governmental organisations, but also the contribution by local co‐organisers at the national level, is crucial for the effectiveness of international citizen science campaigns. In addition, facilitators and barriers of communication need to be considered in each region separately as even at the European scale, we observed a high variability of environmental and socio‐cultural settings. Synthesis . In an era of detrimental consequences of human activities on natural ecosystems, it is vital to include society in observations to determine the impact of environmental change on biodiversity through citizen science approaches. Substantial advances in technological tools have helped to foster these initiatives across vast spatial scales. Nevertheless, it is also crucial to select the right pathways for communication to compete with vast amounts of other information and to reach potential participants in varying socio‐cultural contexts of different countries.

We analyzed data from 52 980 vegetation plots spanning all major grassland habitats in Europe (including alpine, rocky, sandy, saline, dry, mesic and wet grasslands). We quantified competitive (C), stress‐tolerant (S), and ruderal (R) strategies for 7858 plant species based on key functional traits and mapped the spatial patterns of C‐, S‐ and R‐strategies across European grasslands. Using random forest models, we evaluated the relative importance of environmental factors in shaping these patterns and explored potential changes in the distribution of C‐, S‐ and R‐strategies under future climate scenarios. We further investigated how these strategies and their environmental drivers vary across grassland habitats. Our results revealed a clear biogeographical gradient in the distribution of C‐, S‐ and R‐strategies from predominantly stress‐tolerant strategies in Mediterranean grasslands to greater representation of competitive and ruderal strategies in temperate regions. Climate and soil factors emerged as major drivers shaping these patterns at the continental scale. Projected responses to future climate change varied among regions: grasslands in the Atlantic and Continental regions were projected to decrease in C‐strategy and increase in both S‐ and R‐strategy representation, whereas grasslands in Arctic and boreal regions exhibited contrasting trends. Mediterranean grasslands were projected to undergo a transition from mainly R‐strategy toward S‐strategy species predominance. Furthermore, the strategy patterns and their key drivers differed among grassland habitats, with patterns largely reflecting habitat‐specific environmental constraints. This study demonstrates the utility of Grime's CSR framework for characterizing broad‐scale patterns of plant adaptive strategies across diverse grassland habitats. It highlights region‐ and habitat‐specific differences in potential responses to future climate change, with implications for targeted grassland management and restoration.

Among plants, animal-pollinated species are particularly threatened because of the negative effects of these factors on pollinators. Heterostyly is a unique reproductive system defined by two or three floral morphs having a distinct position of anthers and style. The spatial separation of reproductive organs, accompanied by a self-incompatibility system, restricts self-pollination and favours pollinator-mediated pollen transfer between different morphs. In this review, we synthesise knowledge about the effects of loss in the area and connectivity of habitats, and related reduction in population size on heterostylous plants.
