Recent developments in environmental DNA (eDNA) metabarcoding suggest that eDNA-based representation of ecological communities can be a promising tool both fundamental research and assessment. However, it is less known, how eDNA performs characterising community-environment relationships at the regional scale compared with traditional sampling methods. Here, we used electrofishing (EF), gillnetting (GN) surveys to compare their congruency taxonomic trait-based structure (oxbow) lake fish structuring mechanisms. proved more effective detecting taxa total samples by traits than EF GN.

Abstract Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, influence ecosystem properties their benefits detriments people. trait data thus represent the basis for a vast area research spanning from evolutionary biology, community functional ecology, biodiversity conservation, landscape management, restoration, biogeography earth system modelling. Since its foundation in 2007, TRY database plant traits has grown continuously. It now provides unprecedented coverage under an open access policy is main used by worldwide. Increasingly, also supports new frontiers trait‐based research, including identification gaps subsequent mobilization or measurement data. To support this development, article we evaluate extent compiled analyse emerging patterns representativeness. Best species achieved categorical traits—almost complete ‘plant growth form’. However, most relevant ecology vegetation modelling are characterized continuous intraspecific variation trait–environmental relationships. These have be measured on individual respective environment. Despite coverage, observe humbling lack completeness representativeness these many aspects. We, therefore, conclude that reducing biases remains key challenge requires coordinated approach measurements. This can only collaboration with initiatives.

In focusing on how organisms' generalizable functional properties (traits) interact mechanistically with environments across spatial scales and levels of biological organization, trait-based approaches provide a powerful framework for attaining synthesis, generality prediction. Trait-based research has considerably improved understanding the assembly, structure functioning plant communities. Further advances in ecology may be achieved by exploring trait-environment relationships non-sessile, heterotrophic organisms such as terrestrial arthropods, which are geographically ubiquitous, ecologically diverse, often important components ecosystems. studies trait databases have recently been compiled groups ants, bees, beetles, butterflies, spiders many others; however, explicit justification, conceptual framework, primary-evidence base burgeoning field 'terrestrial arthropod ecology' not well established. Consequently, there is some confusion over scope relevance this field, tendency to overlook assumptions approach. Here we aim broad accessible overview arthropods. We first define illustrate foundational concepts respect justify application study their ecology. Next, review community where used elucidate assembly processes communities influenced niche filtering along environmental gradients (e.g. climatic, structural, land-use gradients) abiotic biotic disturbances fire, floods, invasions). also ecosystem investigate biodiversity-ecosystem function relationships: diversity relates host functions services that they mediate, decomposition, pollination predation. then suggest future work can address fundamental limitations investigating functionality effects intraspecific variation, assessing potential sampling methods bias traits values observed, enhancing quality consolidation information databases. A roadmap guide observational presented. Lastly, highlight new areas arthropods positioned advance ecological application. These include examining roles competitive, non-competitive (multi-)trophic interactions shaping coexistence, macro-scaling explain predict patterns biodiversity space time. hope will spur applications insights from most diverse eukaryotic Earth.

Abstract Trait‐based ecology aims to understand the processes that generate overarching diversity of organismal traits and their influence on ecosystem functioning. Achieving this goal requires simplifying complexity in synthetic axes defining a trait space cluster species based while identifying those with unique combinations traits. However, so far, we know little about dimensionality, robustness omission structure these spaces. Here, propose unified framework synthesis across 30 datasets representing broad variety taxa, ecosystems spatial scales show common trade‐off between quality operationality appears three six dimensions. The is generally low but highly variable among datasets. We also highlight invariant scaling relationships, whatever complexity, number clusters, dominant total richness. When richness increases, saturates, whereas tend disproportionately pack richest cluster. Based results, some rules thumb build spaces estimate subsequent functional indices.

Intensive agriculture has major negative impacts on ecosystem diversity and functioning, including that of soils. The associated reduction soil biodiversity essential functions, such as nutrient cycling, can restrict plant growth crop yield. By increasing in agricultural systems, intercropping could be a promising way to foster microbial functioning. However, plant–microbe interactions the extent which they influence yield under field conditions are still poorly understood. In this study, we performed an extensive experiment using eight species 40 different mixtures investigate how affects activity, whether these changes subsequently affect Experiments were carried out mesocosms natural Switzerland Spain, two countries with drastically soils climate, our communities included either one, or four species.

Abstract Organismal functional strategies form a continuum from slow- to fast-growing organisms, in response common drivers such as resource availability and disturbance. However, whether there is synchronisation of these at the entire community level unclear. Here, we combine trait data for >2800 above- belowground taxa 14 trophic guilds spanning disturbance gradient German grasslands. The results indicate that most consistently respond through both direct trophically mediated effects, resulting ‘slow-fast’ axis community. Using 15 indicators carbon nutrient fluxes, biomass production decomposition, also show fast communities are associated with faster rates ecosystem functioning. These findings demonstrate ‘slow’ ‘fast’ can be manifested whole communities, opening new avenues ecosystem-level classification.
