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.

Vegetation phenology has lately gained attention in the context of studying human-induced climate change and its effects on terrestrial ecosystems. It is typically studied various regional temporal scales. This research focused microscale dolines Northernmost part Dinaric Alps.

Peculiarities of the formation of phytocoenotic ranges of vegetatively propagated herbs and shrubs in forest plant groups of the Ukrainian Polissia

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. They also serve living places for numerous vulnerable endemic species, reservoirs genetic resources. Therefore, extremely ecologically valuable, their is balanced functioning planet. Our studies were conducted Desna-Stara Huta National Nature Park, located Ukrainian Polissia. materials methods study included systematic collection data on frequency occurrence vegetatively propagated herbs For analysis, we used statistical methods.

Mixed signals of environmental change and a trend towards ecological homogenization in ground vegetation across different forest types

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. Our results point importance local stand dynamics overstorey explaining temporal trends vegetation. Ground Slovenian is directions dictated multiple regional global drivers.

More losses than gains? Distribution models predict species-specific shifts in climatic suitability for European beech forest herbs under climate change

Frontiers in Forests and Global Change, Год журнала: 2023, Номер 6

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.
