“…In addition, functional traits, such as species temperature tolerance and drought resistance, are often missing or inferred from the abiotic conditions at the (micro)habitats where they have been observed and not measured directly on individuals. However, (micro) habitat selection of species and realized niche in general might result from interactions between species rather than physiological and phenological characteristics of single individuals and populations (Colwell & Fuentes 1975;Ellers, Dias & Berg 2010;Araujo et al 2013;Colas et al 2014;He & Bertness 2014), but see also Warren, Giladi & Bradford (2010). The use of such inferred traits as predictors of community and ecosystem processes has been strongly discouraged (Violle et al 2007), advocating for traits to be measured on individual organisms.…”

Summary 1.Trait-based approaches are increasingly being used to test mechanisms underlying species assemblages and biotic interactions across a wide range of organisms including terrestrial arthropods and to investigate consequences for ecosystem processes. Such an approach relies on the standardized measurement of functional traits that can be applied across taxa and regions. Currently, however, unified methods of trait measurements are lacking for terrestrial arthropods and related macroinvertebrates (terrestrial invertebrates hereafter). 2. Here, we present a comprehensive review and detailed protocol for a set of 29 traits known to be sensitive to global stressors and to affect ecosystem processes and services. We give recommendations how to measure these traits under standardized conditions across various terrestrial invertebrate taxonomic groups. 3. We provide considerations and approaches that apply to almost all traits described, such as the selection of species and individuals needed for the measurements, the importance of intraspecific trait variability, how many populations or communities to sample and over which spatial scales. 4. The approaches outlined here provide a means to improve the reliability and predictive power of functional traits to explain community assembly, species diversity patterns and ecosystem processes and services within and across taxa and trophic levels, allowing comparison of studies and running meta-analyses across regions and ecosystems. Ecology 2017Ecology , 31, 558-567 doi: 10.1111Ecology /1365Ecology -2435 5. This handbook is a crucial first step towards standardizing trait methodology across the most studied terrestrial invertebrate groups, and the protocols are aimed to balance general applicability and requirements for special cases or particular taxa. Therefore, we envision this handbook as a common platform to which researchers can further provide methodological input for additional special cases.

correlated with nitrate removal were silt and mud with microphytes (as substrate 57 preference), and with fine sediment with microorganisms, and dead animals (as food 58 sources). These results agreed with the hypothesis of top-down control and enhanced 59 understanding of the influence of hydromorphological factors on nitrate removal. 60 5. This study highlights the involvement of the macroinvertebrate community in 61 in-stream nitrate processing, and demonstrates the usefulness of applying a functional 62 approach to explaining relationships between biodiversity and ecosystem function. 63 64

Two microcrustaceans affect microbial and macroinvertebrate‐driven litter breakdown

Summary Leaf litter degradation in fresh waters is a fundamental ecosystem process performed by a wide array of decomposers. The meiofauna is an important component of aquatic heterotrophic assemblages, which can provide a trophic link between plant detritus and associated microbial and macroinvertebrate communities, but their contribution to leaf breakdown remains poorly understood. We hypothesised that, through their feeding activity, microcrustaceans influence the structure of fungal assemblages and consequently microbially mediated litter breakdown. Litter‐associated microcrustaceans were predicted to change the pathways of energy transfer in the food web according to the positive (e.g. complementarity) or negative (e.g. predation) interactions with macroinvertebrate detritivore taxa. We evaluated experimentally in the laboratory, over 6 and 13 days, the potential contribution of two freshwater microcrustaceans (a cladoceran and a copepod) to litter breakdown in the presence of microfungi (aquatic hyphomycetes), with and without macroinvertebrate detritivores (a trichopteran and a gammarid amphipod). The presence of microcrustaceans enhanced leaf mass loss by 62 and 22% in treatments with fungi or trichopteran alone, respectively, while no significant effect was observed for treatments with the amphipod. Microcrustaceans strongly increased the production of fine particulate organic matter, particularly in treatments with fungi alone (+637%). The leaf consumption rate by the amphipod significantly decreased (−61%) at 13 days in the presence of microcrustaceans, likely due to predation on cladocerans. Our study supports the potential role of microcrustaceans in the detrital food web of streams and rivers. Interestingly, microcrustaceans may interact with microbial and macroinvertebrate decomposers in either positive or negative ways. Therefore, microcrustaceans add complexity to detrital food webs by increasing vertical diversity and modulating biotic interactions with important consequences for carbon and energy transfers in stream ecosystems.
