Accurate mapping of species distributions is a fundamental goal modern biogeography, both for basic and applied purposes. This commonly done by plotting known occurrences, expert-drawn range maps or geographical estimations derived from distribution models. However, all three kinds are implicitly subject to uncertainty, due the quality bias raw distributional data, process map building, dynamic nature themselves. Here we review main sources uncertainty suggesting code good practices in order...
Abstract Aims Ellenberg‐type indicator values are expert‐based rankings of plant species according to their ecological optima on main environmental gradients. Here we extend the indicator‐value system proposed by Heinz Ellenberg and co‐authors for Central Europe incorporating other systems (i.e., those using scales compatible with values) developed European regions. Our aim is create a harmonized data set applicable at scale. Methods We collected sets vascular plants selected 13 that used...
We discuss the usefulness of concept Potential Natural Vegetation (PNV), which describes expected state mature vegetation in absence human intervention. argue that it is impossible to model PNV because (i) methodological problems associated its definition and (ii) issues related ecosystems dynamics.We conclude approach characterizing unrealistic provides scenarios with limited predictive power. In places a long-term history, interpretations need be very cautious, explicit acknowledgement...
Various ecological mechanisms influence the forms of species richness relationships (SRRs). These can be gathered under five general categories: more individuals, environmental heterogeneity, dispersal limitations, biotic interactions, and multiple pools. Often only first two categories are discussed. In contrast, we examine all explore how they form SRRs. We discuss various sampling schemes methods SRR construction used to gain insight about processes patterns. The field is ripe for probing...
GrassPlot is a collaborative vegetation-plot database organised by the Eurasian Dry Grassland Group (EDGG) and listed in Global Index of Vegetation-Plot Databases (GIVD ID EU-00-003).GrassPlot collects plot records (relevés) from grasslands other open habitats Palaearctic biogeographic realm.It focuses on precisely delimited plots eight standard grain sizes (0.0001; 0.001; ... 1,000 m²) nested-plot series with at least four different sizes.The usage regulated through bylaws that intend to...
Abstract Aim Species–area relationships (SARs) are fundamental scaling laws in ecology although their shape is still disputed. At larger areas, power best represent SARs. Yet, it remains unclear whether SARs follow other shapes at finer spatial grains continuous vegetation. We asked which function describes small and explored how sampling methodology or the environment influence SAR shape. Location Palaearctic grasslands non‐forested habitats. Taxa Vascular plants, bryophytes lichens....
Abstract Aims Understanding fine‐grain diversity patterns across large spatial extents is fundamental for macroecological research and biodiversity conservation. Using the GrassPlot database, we provide benchmarks of richness values Palaearctic open habitats vascular plants, bryophytes, lichens complete vegetation (i.e., sum former three groups). Location biogeographic realm. Methods We used 126,524 plots eight standard grain sizes from database: 0.0001, 0.001, 0.01, 0.1, 1, 10, 100 1,000 m...
Abstract Motivation Indicator values are numerical used to characterize the ecological niches of species and estimate their occurrence along gradients. on climatic edaphic plant have received considerable attention in research, whereas data optimal positioning disturbance gradients less developed. Here, we present a new set indicator identifying optima natural anthropogenic for 6382 vascular based analysis 736,366 European vegetation plots using expert‐based characterization regimes 236...
Abstract Ecological theory predicts close relationships between macroclimate and functional traits. Yet, global climatic gradients correlate only weakly with the trait composition of local plant communities, suggesting that important factors have been ignored. Here, we investigate consistency climate-trait for communities in European habitats. Assuming are better accounted more narrowly defined habitats, assigned > 300,000 vegetation plots to hierarchically classified habitats modelled...
Abstract Aims The Raunkiær's system classifies vascular plants into life forms based on the position of renewal buds during periods unfavourable for plant growth. Despite importance ecological research, a study exploring diversity and distribution continental scale is missing. We aim to (i) map in European vegetation (ii) test effects bioclimatic variables while controlling habitat‐specific responses. Location Europe. Methods used data 8883 species recorded 546,501 plots different habitats...
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...
Anthropogenic biodiversity decline threatens the functioning of ecosystems and many benefits they provide to humanity1. As well as causing species losses in directly affected locations, human influence might also reduce relatively unmodified vegetation if far-reaching anthropogenic effects trigger local extinctions hinder recolonization. Here we show that plant diversity is globally negatively related level activity surrounding region. Impoverishment natural was evident only when considered...
Abstract. The efficiency of four nonparametric species richness estimators — first‐order Jackknife, second‐order Chao2 and Bootstrap was tested using simulated quadrat sampling two field data sets (a sandy ‘Dune’ adjacent ‘Swale’) in high diversity shrublands (kwongan) south‐western Australia. each comprised > 100 perennial plant 10 000 individuals, the explicit ( x‐y co‐ordinate) location every individual. We applied strategies to these based on quadrats unit sizes 1/400th 1/100th total...
Abstract Protected areas (PAs) constitute major tools in nature conservation. In the European Union (EU), Birds and Habitats Directives are most important policies for conservation strategy, legally preserving Europe’s characteristic, rare, endemic threatened biota. We used occurrence data species listed directives’ Annexes to assess uniqueness of PAs EU (National Parks, Biosphere Reserves); this is EU’s focal species. developed a novel, multifunctional approach calculate different metrics...
