DNA metabarcoding is promising for cost-effective biodiversity monitoring, but reliable diversity estimates are difficult to achieve and validate. Here we present validate a method, called LULU, removing erroneous molecular operational taxonomic units (OTUs) from community data derived by high-throughput sequencing of amplified marker genes. LULU identifies errors combining sequence similarity co-occurrence patterns. To the use unique set high quality survey vascular plants paired with plant...
Trophic rewilding is an ecological restoration strategy that uses species introductions to restore top-down trophic interactions and associated cascades promote self-regulating biodiverse ecosystems. Given the importance of large animals in their widespread losses resulting downgrading, it often focuses on restoring functional megafaunas. increasingly being implemented for conservation, but remains controversial. Here, we provide a synthesis its current scientific basis, highlighting as key...
Abstract The European Vegetation Archive ( EVA ) is a centralized database of vegetation plots developed by the IAVS Working Group Survey. It has been in development since 2012 and first made available for use research projects 2014. stores copies national regional vegetation‐ plot databases on single software platform. Data storage does not affect on‐going independent contributing databases, which remain property data contributors. uses prototype management TURBOVEG 3 joint multiple that...
Abstract Aims Vegetation‐plot records provide information on the presence and cover or abundance of plants co‐occurring in same community. data are spread across research groups, environmental agencies biodiversity centers and, thus, rarely accessible at continental global scales. Here we present sPlot database, which collates vegetation plots worldwide to allow for exploration patterns taxonomic, functional phylogenetic diversity plant community level. Results version 2.1 contains from...
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...
The extensive, prehistoric loss of megafauna during the last 50 000 years led early naturalists to build founding theories ecology based on already‐degraded ecosystems. In this article, we outline how large herbivores affect community ecology, with a special focus plants, through changes selection, speciation, drift, and dispersal, thereby directly impacting ecosystem diversity functionality. However, attempts quantify effects processes are markedly scarce in past contemporary studies. We...

The impact of large herbivores on ecosystems before modern human activities is an open question in ecology and conservation. For Europe, the controversial wood-pasture hypothesis posits that grazing by wild supported a dynamic mosaic vegetation structures at landscape scale under temperate conditions agriculture. contrasting position suggests European was primarily closed forest with relatively small areas, most impacted locally herbivores. Given role humans world-wide decimations megafauna...
Summary Most plant species have a range of traits that deter herbivores. However, understanding how different defences are related to one another is surprisingly weak. Many authors argue defence trade off against another, while others they form coordinated syndromes. We collected dataset unprecedented taxonomic and geographic scope (261 spanning 80 families, from 75 sites across the globe) investigate relationships among four chemical six physical defences. Five 45 pairwise correlations...
Abstract Correlations among plant traits often reflect important trade‐offs or allometric relationships in biological functions like carbon gain, support, water uptake, and reproduction that are associated with different organs. Whether trait correlations can be aggregated to “spectra” “leading dimensions,” whether these dimensions consistent across organs, spatial scale, growth forms still open questions. To illustrate the current state of knowledge, we constructed a network published “leaf...
Abstract Large herbivores provide key ecosystem processes, but have experienced massive historical losses and are under intense pressure, leaving current ecosystems with dramatically simplified faunas relative to the long‐term evolutionary norm. Hampered by a shifting baseline, natural levels of large‐herbivore biomass poorly understood seldom targeted. This ‘Decade restoration’ calls for evidence‐based targets restoring diversity large herbivores. We apply scaling consumer–producer...
Abstract Aims We introduce ReSurveyEurope — a new data source of resurveyed vegetation plots in Europe, compiled by collaborative network scientists. describe the scope this initiative, provide an overview currently available data, governance, contribution rules, and accessibility. In addition, we outline further steps, including potential research questions. Results includes from all habitats. Version 1.0 contains 283,135 observations (i.e., individual surveys each plot) 79,190 sampled 449...
It is hard to defend the view that biotic communities represent a simple and predictable response abiotic environment. Biota environment interact, of an individual certainly includes its neighbors visitors in community. The complexity community assembly calls forth quest for general principles, yet current results theories on rules differ widely. Using grassland microcosm as model system, we manipulated fertility, disturbance by defoliation, soil/microclimate, arrival order species belonging...
The inclusion of environmental variation in studies recruitment is a prerequisite for realistic predictions the responses vegetation to changing environment. We investigated how seedling affected by seed availability and microsite quality along steep gradient dry tundra. A survey natural rain density was combined with observations establishment 14 species after sowing into intact or disturbed vegetation. Although closely correlated establishment, experimental addition showed that environment...
Predator–prey interactions play an important role for species composition and community dynamics at local scales, but their importance in shaping large‐scale gradients of richness remains unexplored. Here, we use global range maps, structural equation models (SEM), comprehensive databases dietary preferences body masses all terrestrial, non‐volant mammals worldwide, to test whether (1) prey bottom‐up or predator top‐down relationships are drivers broad‐scale once the environment human...
Abstract Plants regulate soils and microclimate, provide substrate for heterotrophic taxa, are easy to observe identify have a stable taxonomy, which strongly justifies their use as indicators in monitoring conservation. However, there is no consensus whether plants strong predictors of total multi‐taxon species richness. In this study, we investigate if general terrestrial richness can be predicted by vascular plant bioindication. To answer question, collected an extensive dataset on...
Abstract Question How does naturalistic grazing (trophic rewilding with large herbivores), in contrast to mowing and free succession (no grazing), affect plant community composition species richness temperate grassland grazed by semi‐feral cattle horses? Location Mols Laboratory, Denmark. Methods We investigated exclosures the area of four years after its establishment. focused on moist dry vegetation, that is, excluding scrub woodland. Each experimental block consisted five 5 × 9 m plots,...
Abstract Question Coastal dunes are a globally distributed ecosystem characterized by roughly linear geography, strong habitat connectivity, and small‐scale internal gradients in disturbance stress. Disturbance, stress competition often considered the main ecological forces driving plant community assembly, but their relative importance coastal is not well elucidated. Phylogenetic structure reflects processes controlling assembly across evolutionary time scales. We investigate for first how...
