Significance The stability of ecological communities under ongoing climate and land-use change is fundamental to the sustainable management natural resources through its effect on critical ecosystem services. Biodiversity hypothesized enhance compensatory effects (decreased synchrony between species). However, relative importance interplay different biotic abiotic drivers remain controversial. By analyzing long-term data from seminatural ecosystems across globe, we found that degree among...
Abstract Analysing temporal patterns in plant communities is extremely important to quantify the extent and consequences of ecological changes, especially considering current biodiversity crisis. Long‐term data collected through regular sampling permanent plots represent most accurate resource study succession, analyse stability a community over time understand mechanisms driving vegetation change. We hereby present LOng‐Term Vegetation Sampling (LOTVS) initiative, global collection...
Abstract Functional and phylogenetic diversity (FD PD respectively) of the resident community are expected to exert a key role in resistance colonization by surrounding species, their establishment success. However, few studies have explored this topic experimentally or evaluated interactive effects these measures. We implemented experiment disentangle FD sowing mixtures 6 drawn from pool 19 species naturally coexisting central European mesic meadows. The were designed cover four independent...
Abstract Aims The link between spectral diversity and in‐situ plant biodiversity is one promising approach to using remote sensing for assessment. Nevertheless, there little evidence as whether this maintained at fine scales, well how it influenced by vegetation's vertical complexity. Here we test, the community level in grasslands, of signal ( S Div ) taxonomic T ), influence Methods We used 196 1.5 m × experimental communities with different levels. To measure complexity, quantified height...
Biodiversity monitoring is constrained by cost- and labour-intensive field sampling methods. Increasing evidence suggests that remotely sensed spectral diversity (SD) linked to plant diversity, holding promise for applications. However, studies testing such a relationship reported conflicting findings, especially in challenging ecosystems as grasslands, due their variety high temporal dynamism. It follows thorough investigation of the key factors influencing these relationships, metrics...
Ecological theory posits that temporal stability patterns in plant populations are associated with differences species' ecological strategies. However, empirical evidence is lacking about which traits, or trade-offs, underlie species stability, especially across different biomes. We compiled a worldwide collection of long-term permanent vegetation records (greater than 7000 plots from 78 datasets) large range habitats we combined existing trait databases. tested whether the observed...
Functional redundancy is considered a major component of the insurance mechanism, which theoretically maintains ecosystem stability by preventing loss functions with species loss. Over past decades, examination functional trait patterns to elucidate processes community and functioning have stimulated considerable amount research in ecology. As result, multitude indices been developed, describing structure various levels overlap their methodology. Here, we review set that suggested measure...
Abstract Questions Compensatory dynamics are described as one of the main mechanisms that increase community stability, e.g., where decreases some species on a year‐to‐year basis offset by an in others. Deviations from perfect synchrony between (asynchrony) have therefore been advocated important mechanism underlying biodiversity effects stability. However, it is unclear to what extent existing measures actually capture signal fluctuations presence long‐term directional trends both abundance...
Abstract While biodiversity is expected to enhance multiple ecosystem functions (EFs), the different roles of dimensions remain difficult disentangle without carefully designed experiments. We sowed plant communities with independent levels functional (FD) and phylogenetic diversities (PD), combined fertilization, investigate their direct indirect on EFs, including plant‐related EFs (plant biomass productivity, litter decomposability), soil fertility (organic carbon nutrient pool variables),...

Summary Ecological theory posits that temporal stability patterns in plant populations are associated with differences species’ ecological strategies. However, empirical evidence is lacking about which traits, or trade-offs, underlie species stability, specially across different ecosystems. To address this, we compiled a global collection of long-term permanent vegetation records (>7000 plots from 78 datasets) wide range habitats and combined this existing trait databases. We tested...
