Summary 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 investigate consequences for ecosystem processes. Such an approach relies on the standardized measurement functional traits that can be applied taxa regions. Currently, however, unified methods trait measurements lacking related macroinvertebrates (terrestrial invertebrates hereafter). Here, we...
Cities can host significant biological diversity. Yet, urbanisation leads to the loss of habitats, species, and functional groups. Understanding how multiple taxa respond globally is essential promote conserve biodiversity in cities. Using a dataset encompassing six terrestrial faunal (amphibians, bats, bees, birds, carabid beetles reptiles) across 379 cities on 6 continents, we show that produces taxon-specific changes trait composition, with traits related reproductive strategy showing...
Mixotrophic protists are increasingly recognized for their significant contribution to carbon (C) cycling. As phototrophs they contribute photosynthetic C fixation, whilst as predators of decomposers, indirectly influence organic matter decomposition. Despite these direct and indirect effects on the cycle, little is known about responses peatland mixotrophs climate change potential consequences cycle. With a combination field microcosm experiments, we show that in Sphagnum bryosphere play an...
Abstract Aim Cities worldwide are characterized by unique human stressors that filter species based on their traits, potentially leading to biodiversity loss. The knowledge of which filtered and at scale is important gain a more mechanistic understanding urban community assembly develop strategies manage impact ecosystems. We investigate the ecological mechanisms shaping assembly, taking into account changes across scales, taxa green space types. Location City Zurich, Switzerland. Taxon...
This review provides a synthesis of current knowledge on the morphological and functional traits testate amoebae, polyphyletic group protists commonly used as proxies past hydrological changes in paleoecological investigations from peatland, lake sediment soil archives. A trait-based approach to understanding amoebae ecology paleoecology has gained popularity recent years, with research showing that characteristics provide complementary information environmental inferences based...
Abstract. Due to their spatial complexity and dynamic nature, floodplains provide a wide range of ecosystem functions. However, because flow regulation, many riverine have lost characteristic heterogeneity. Restoration floodplain habitats the rehabilitation key functions, them linked organic carbon (C) dynamics in riparian soils, has therefore become major goal environmental policy. The fundamental understanding factors that drive processes involved C cycling heterogeneous systems such as is...
Abstract Aim Patterns of α‐ and β‐diversity soil protist communities the factors that shape them remain largely unknown. We undertook a world‐wide survey forest litter to investigate patterns diversity in group testate amoebae. aimed assess: (1) whether there is latitudinal gradient α‐diversity, (2) was correlated solely with environmental commonly used biology research or if it also independently explained by geographical barriers. Location World‐wide. Methods studied Euglyphida, common...
Species distribution in a metacommunity varies according to their traits, the of environmental conditions and connectivity among localities. These ingredients contribute coexistence across spatial scales via species sorting, patch dynamics, mass effects neutral dynamics. mechanisms however seldom act isolation impact landscape configuration on relative importance remains poorly understood. We present new model dynamics that simultaneously considers these four possible over spatially explicit...
Recent studies show that soil eukaryotic diversity is immense and dominated by micro-organisms. However, it unclear to what extent the processes shape distribution of in plants animals also apply Major diversification events multicellular organisms have often been attributed long-term climatic geological processes, but impact such on protist has received much less attention as their believed be largely cosmopolitan. Here, we quantified phylogeographical patterns Hyalosphenia papilio, a large...
The complexity of ecological systems is a major challenge for practitioners and decision-makers who work to avoid, mitigate manage environmental change. Here, we illustrate how metaecology – the study spatial interdependencies among through fluxes organisms, energy, matter can enhance understanding improve managing change at multiple scales. We present several case studies illustrating framework has leveraged decision-making in conservation, restoration risk management. Nevertheless, an...
Cities are socioecological systems that filter and select species, therefore establishing unique species assemblages biotic interactions. Urban ecosystems can host richer wild bee communities than highly intensified agricultural areas, specifically in resource-rich urban green spaces such as allotments family gardens. At the same time, beekeeping has boomed many European cities, raising concerns fast addition of a large number managed bees could deplete existing floral resources, triggering...
Subfossil remains of various groups organisms preserved in peat and sediment archives are commonly used to infer past environmental changes using transfer functions based on species composition. However, the community structure can also be explored functional trait approach. Investigation traits palaeoecological records inform about mechanisms through which abiotic variables such as temperature or moisture impact communities. Moreover, provide information ecosystem functioning potentially...
Summary Trait‐based approaches can reveal the mechanisms through which disturbances or stress impact communities, allowing comparisons of role different in shaping communities among taxonomic groups. Such information lead to higher comparability, transferability and predictability outcome restoration projects. However, multitaxa trait‐based were rarely used context ecosystem restoration. We investigated responses environmental gradients seven taxa (vascular plants, staphylinid carabid...
Abstract Aim To assess the largely neglected patterns and causes of latitudinal diversity gradients in soil protists, using South American testate amoebae as model organisms. Location South‐western America (SSA). Methods We assessed relationship among richness, latitude predictions eight ecological hypotheses SSA, a region characterized by harsh abiotic conditions northward southward from mid‐latitudes. also examined variation species range sizes, composition phylogenetic relatedness to...
Biodiversity loss and widespread ecosystem degradation are among the most pressing challenges of our time, requiring urgent action. Yet understanding their causes remains limited because prevailing ecological concepts approaches often overlook underlying complex interactions individuals same or different species, interacting with each other environment. We propose a paradigm shift in science, moving from simplifying frameworks that use population community averages to an integrative approach...
