ABSTRACT Many years of land use transformation within river valleys have drastically changed these ecosystems. Black poplar is a tree species characteristic riparian habitats, but due to specific environmental requirements, their populations difficulties with natural regeneration. Here, we genotyped 623 black individuals from four located along different sections the Vistula River. This river, which largest in Poland, characterized by variable degrees regulation and its environment. Each population consisted group mature trees naturally regenerated trees. Our main goal was assess differences between gene pools regenerations. The results showed that all were high comparable values parameters genetic diversity. Despite this, distinguished two three clusters (depending on method). differentiation among regeneration groups almost twice as groups. most regenerations diverged except for one population. also only where fully generative occurred, growing least transformed middle section river. research confirms need monitor seedlings saplings major rivers conduct molecular analyses pools. It can be assumed lack suitable areas seed germination, will reproduce mainly vegetatively, may way ensure survival species. However, adaptive potential youngest generations unknown, especially face progressive climate change. We conclude preserve resources, ex situ protection form local clone archives necessary.

Abstract The distylous plant Primula veris has long served as a model species for studying heterostyly, that is the occurrence of multiple floral morphs within population to ensure outcrossing. Habitat loss, reduced sizes, and climate change have raised concerns about impact these factors on morph ratios related consequences fitness heterostylous species. We studied deviation P. from isoplethy (i.e. equal frequency) in response size, landscape context climatic factors, based pan‐European citizen science campaign involving observations 28 countries. In addition, we examined relative frequency determine whether disrupt frequencies or specific an advantage over other. Theory predicts short‐styled S‐morphs long‐styled L‐morphs populations at equilibrium. However, data >3000 showed substantial significant excess (9% higher compared L‐morphs). Deviation equilibrium was substantially stronger smaller not affected by identity. Higher summer precipitation land use intensity were associated with increased prevalence S‐morphs.

Genotyping CYP734A50 gene S locus, which determines length position , revealed no mutations this region. Our results unprecedented geographic sampling suggest changes may be responsible non‐equilibrium frequencies.

Forest ecosystems are characterized by a vast biological diversity, comprising millions of plants, animals, fungi, and microorganisms, which interact form complex food chains interdependencies. contain several strata, from the litter vegetation shrubs to tree tops, each supporting an array life forms performing specific functions. The upper tier forest provides protection sun, thus controlling microclimate at lower levels, influencing temperatire soil humidity. Forests play crucial role in global biogeochemical cycles, such as carbon water cycles. Trees consume dioxide emissions atmosphere produce oxygen through phosynthesis, mitigating climate change. Water circulates ecosystems, evaporates leaf surface, condenses clouds, returns back Earth precipitation. continuously change subject both natural anthropogenic factors. provide variety ecosystemic services, ranging regulation preservation soils filtration support biodiversity.

Abstract Forest ground vegetation may serve as an early warning system for monitoring anthropogenic global-change impacts on temperate forests. Climate warming induce a decline of cool-adapted species to the benefit more thermophilous plants. Nitrogen deposition has been documented potentially result in soil eutrophication or acidification, which can increase proportion with higher nutrient requirements and impoverishment caused by competitive exclusion. Abiotic forest disturbances are changing light conditions understorey environment. In this resurvey study, we tested magnitude direction change alpha (species richness) beta (within-site dissimilarity) diversity composition forests different types Slovenia over fifteen years. Using plant-derived characteristics (Ellenberg-type indicator values) testing priori predictions concerning expected effects environmental drivers, show that floristic changes varies greatly between sites. Divergent responses at sites resulted low net weak overall signal. The largest decrease number was observed lowland oak-hornbeam forests, were also among greatest compositional shifts. Changes did not any consistent trend, anticipated convergence confirmed when all considered. Thermophilization mainly detected montane beech alpine spruce whereas signal most significant nutrient-poor Vegetation strongly dependent initial site conditions. Shrinkage ecological gradients (process homogenization) suggests positioned ends losing their original character becoming similar mid-gradient generally exhibit smaller changes.

Introduction Herbaceous plant species constitute an essential element of the flora European beech ( Fagus sylvatica ) forests. There is increasing evidence that rapidly changing climate likely to modify spatial distribution species. However, we lack understanding impact change might have on forest herbs across continent. We investigated possible effects predicted rates global warming and altered precipitation regimes 71 closely associated with forests, but varying biogeographic climatic niche attributes. Methods By using a total 394,502 occurrence records ensemble models (SDMs), quantified potential current future (2061-2080) range shifts in suitability (expressed as probability, OP) according two scenarios (moderate SSP2-4.5 severe SSP5-8.5). Results Overall, warmest quarter temperature seasonality were most influential predictors shaping patterns. For SSP5-8.5 scenario, all studied experienced significant reductions (52.9% average) size highly suitable areas (OP >0.75). magnitude directions changes species-specific; few even increase OP future, particularly case scenario. The SDMs revealed substantial decline at trailing edges southern Europe. found show unidirectional northward shift move toward higher elevations. gain/loss ratio was generally for narrow-ranged compared widespread taxa. Discussion Our findings are contextualized regards confounding factors (dispersal limitation, microclimatic buffering) may mitigate or accelerate impacts. Given low long-distance migration ability, many unlikely track velocity which macroclimatic isotherms moving latitudes, making this group vulnerable change.
