Significance Around the globe, climate warming is increasing dominance of warm-adapted species—a process described as “thermophilization.” However, thermophilization often lags behind itself, with some recent studies showing no response at all. Using a unique database more than 1,400 resurveyed vegetation plots in forests across Europe and North America, we document significant understory vegetation. to macroclimate was attenuated whose canopies have become denser. This microclimatic effect...
Local factors restrain forest warming Microclimates are key to understanding how organisms and ecosystems respond macroclimate change, yet they frequently neglected when studying biotic responses global change. Zellweger et al. provide a long-term, continental-scale assessment of the effects micro- on community composition European forests (see Perspective by Lembrechts Nijs). They show that changes in canopy cover fundamentally important for driving climate Closed canopies buffer against...
1 Disturbance may cause community composition across sites to become more or less homogenous, depending on the importance of different processes involved in assembly. In north-eastern North America and Europe local (alpha) diversity forest plants is lower forests growing former agricultural fields (recent forests) than older (ancient) forests, but little known about influence land-use history degree compositional differentiation among (beta diversity). 2 Here we analyse data from 1446...
Summary 1. Atmospheric nitrogen (N) deposition is expected to change forest understorey plant community composition and diversity, but results of experimental addition studies observational are not yet conclusive. A shortcoming studies, which generally based on resurveys or sampling along large gradients, the occurrence temporal spatial confounding factors. 2. We were able assess contribution N versus other ecological drivers communities by combining a approach. Data from 1205...
Abstract Recent studies from mountainous areas of small spatial extent (<2500 km 2 ) suggest that fine‐grained thermal variability over tens or hundreds metres exceeds much the climate warming expected for coming decades. Such in temperature provides buffering to mitigate climate‐change impacts. Is this local restricted topographically complex terrains? To answer this, we here study across a 2500‐km wide latitudinal gradient N orthern E urope encompassing large array topographic...
Abstract The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems ( https://www.nhm.ac.uk/our-science/our-work/biodiversity/predicts.html )—has collated from published studies a large, reasonably representative database comparable samples biodiversity multiple sites that differ in the nature or intensity human impacts relating to land use. We have used this evidence base develop global and regional statistical models how local responds these measures....
With the aim of wood production with negligible negative effects on biodiversity and ecosystem processes, a silvicultural practice selective logging natural regeneration has been implemented in European beech forests (Fagus sylvatica) during last decades. Despite this near-to-nature strategy, species richness various taxa is lower these than unmanaged forests. To develop guidelines to minimize fundamental weaknesses current practice, we linked functional traits saproxylic beetle...
Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction alien species. Existing global databases species' threat status or population time series are dominated by charismatic The collation datasets with broad taxonomic biogeographic extents, that support computation a range biodiversity indicators, is necessary enable better understanding historical declines project - avert future declines.

Forest understorey microclimates are often buffered against extreme heat or cold, with important implications for the organisms living in these environments. We quantified seasonal effects of microclimate predictors describing canopy structure, composition and topography (i.e., local factors) forest patch size distance to coast landscape factors).Temperate forests Europe.2017-2018.Woody plants.We combined data from a sensor network weather-station records calculate difference, offset,...
1 We studied the migration of field layer plants across ecotones between ancient woodlands and recent deciduous woods on former arable land varying in age 30 75 years. 2 Number percentage cover woodland species decreased with increasing distance to woods, increased indicating dispersal limitation during secondary succession. 3 Colonization by typical was observed 183 200 × site combinations. In 72 combinations, a colonization front characterized logarithmic or linear decrease cover,...
Global warming has created a need for studies along climatic gradients to assess the effects of temperature on ecological processes. Altitudinal and latitudinal are often used as such, usually in combination with air data from closest weather station recorded at 1.5–2 m above ground. However, many processes occur in, at, or right soil surface. To evaluate how representative commonly microclimate relevant surface biota, we compared temperatures an altitudinal (500–900 a.s.l.) gradient...
Abstract Slow‐colonizing forest understorey plants are probably not able to rapidly adjust their distribution range following large‐scale climate change. Therefore, the acclimation potential change within actual occupied habitats will likely be key for short‐ and long‐term persistence. We combined transplant experiments along a latitudinal gradient with open‐top chambers assess effects of temperature on phenology, growth reproductive performance multiple populations slow‐colonizing plants,...
Abstract Aim Woodlands make up a third of European territory and carry out important ecosystem functions, yet comprehensive overview their invasion by alien plants has never been undertaken across this continent. Location Europe. Methods We extracted data from 251,740 vegetation plots stored in the recently compiled Vegetation Archive. After filtering (resulting 83,396 plots; 39 regions; 1970–2015 time period), we analysed species pool frequency vascular with respect to geographic origin...
Summary 1. Worldwide, the floristic composition of temperate forests bears imprint past land use for decades to centuries as regrow on agricultural land. Many species, however, display significant interregional variation in their ability (re)colonize post‐agricultural forests. This colonization across regions and underlying factors remain largely unexplored. 2. We compiled data 90 species 812 × study combinations from 18 studies Europe that determined species’ distribution patterns ancient...
Abstract Aim Formalized classifications synthesizing vegetation data at the continental scale are being attempted only now, although they of key importance for nature conservation planning. Therefore, we aim to provide a classification and describe main biogeographical patterns floodplain forests alder carrs in Europe. Location Methods A database more than 40 000 plots across Europe was compiled. After geographic stratification, 16 392 were available classification, which performed using...
Abstract The contemporary state of functional traits and species richness in plant communities depends on legacy effects past disturbances. Whether temporal responses community properties to current environmental changes are altered by such legacies is, however, unknown. We expect global interact with land‐use given different trajectories initiated prior management, subsequent resources conditions. tested this expectation for using 1814 survey‐resurvey plot pairs understorey from 40 European...
More and more ecologists have started to resurvey communities sampled in earlier decades determine long-term shifts community composition infer the likely drivers of ecological changes observed. However, assess relative importance of, interactions among, multiple joint analyses data from many regions spanning large environmental gradients are needed. In this paper we illustrate how combining can increase likelihood driver-orthogonality within design show that repeatedly surveying across...
