Abstract For managed temperate forests, conservationists and policymakers favour fine‐grained uneven‐aged (UEA) management over more traditional coarse‐grained even‐aged (EA) management, based on the assumption that within‐stand habitat heterogeneity enhances biodiversity. There is, however, little empirical evidence to support this assumption. We investigated for first time how differently grained forest systems affect biodiversity of multiple above‐ below‐ground taxa across spatial scales....
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,...
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...
Abstract A central challenge of today's ecological research is predicting how ecosystems will develop under future global change. Accurate predictions are complicated by (a) simultaneous effects different drivers, such as climate change, nitrogen deposition and management changes; (b) legacy from previous land use. We tested whether herb layer biodiversity (i.e. richness, Shannon diversity evenness) functional cover, specific leaf area [SLA] plant height) responses to environmental change...
Abstract Forecasting the growth of tree species to future environmental changes requires a better understanding its determinants. Tree is known respond global‐change drivers such as climate change or atmospheric deposition, well local land‐use forest management. Yet, large geographical scale studies examining interactive responses multiple are relatively scarce and rarely consider management effects. Here, we assessed effects three (temperature, precipitation nitrogen deposition) on...
Abstract Functional traits respond to environmental drivers, hence evaluating trait‐environment relationships across spatial gradients can help understand how multiple drivers influence plant communities. Global‐change such as changes in atmospheric nitrogen deposition occur worldwide, but affect community trait distributions at the local scale, where resources (e.g. light availability) and conditions soil pH) also We investigate responses related resource acquisition (plant height, specific...
Abstract Forest management greatly influences biodiversity across spatial scales. At the landscape scale, combining systems that create different stand properties might promote due to complementary species assemblages. In European beech forests, nature conservation and policy advocate a mixture of unmanaged (UNM) forests uneven‐aged (UEA) managed at fine grain expense traditionally even‐aged shelterwood (EA). Evidence such composition enhances forest is still missing. We studied (species...
Abstract Knowledge on mesoclimatic zonation and microclimatic variations within mountain forest ecosystems is crucial for understanding regional species turnover effects of climate change these systems. The temperate forests in the Andean region South America are among largest contiguous natural deciduous areas world. Due to their pronounced disturbance regime different successional stages, a climatic combined with characterisation its variation important identify thresholds occurrences. We...

Abstract Questions How do vegetation changes in a limestone beech forest community on dry and nutrient‐poor slopes differ from moist nutrient‐rich soils over the past 50 yr?

Tree species diversity can positively affect the multifunctionality of forests. This is why conifer monocultures Scots pine and Norway spruce, widely promoted in Central Europe since 18th 19th century, are currently converted into mixed stands with naturally dominant European beech. Biodiversity expected to benefit from these mixtures compared pure due increased abiotic biotic resource heterogeneity. Evidence for this assumption is, however, largely lacking. Here, we investigated vascular...
Abstract The understorey in temperate forests can play an important functional role, depending on its biomass and characteristics. While it is known that local soil stand characteristics largely determine the of understorey, less about role global change. Global change directly affect biomass, but also indirectly by modifying overstorey, resource availability growing conditions at forest floor. In this observational study across Europe, we aim disentangling impact global‐change drivers...
Changing ecosystem conditions and diverse socio-economical events have contributed to an ingrained presence of non-native tree species (NNTs) in the natural cultural European landscapes. Recent research endeavors focused on different aspects NNTs such as legislation, benefits, risks for forestry, emphasizing that large knowledge gaps remain. As attempt fulfill part these gaps, within PEN-CAFoRR COST Action (CA19128) network, we established open-access questionnaire allows both academic...
Abstract Questions Light availability at the forest floor affects many ecosystem processes, and is often quantified indirectly through easy‐to‐measure stand characteristics. We investigated how three such characteristics, basal area, canopy cover closure, were related to each other in structurally complex mixed forests. also asked well they can predict light‐demand signature of understorey (estimated as mean Ellenberg indicator value for light [“ EIV LIGHT ”] proportion “forest specialists”...
Abstract Schall et al. (2020) assessed how a combination of different forest management systems in managed landscapes dominated by European beech may affect the biodiversity (alpha, beta and gamma) 14 taxonomic groups. Current policy nature conservation often demand for combining uneven‐aged unmanaged, set‐aside conservation, forests order to promote biodiversity. In contrast this, found even‐aged shelterwood forests, represented developmental phases, support highest regional (gamma)...

However, open areas within (e.g. clearcuts), current version underestimates biomass produces unreliable pool estimations. Thus, tissue density, as approximated leaf matter content...
