Summary Stream ecosystem metabolism integrates production and respiration of organic matter plays a fundamental role in the global carbon (C) cycle. Several studies have identified distal proximal physical controls, for example, land use transient storage, or effects water chemistry, that is, nutrient availability, on stream metabolism. In parallel, research quality has conspicuous gradients chemical composition, yet mostly without demonstrating any functional implications. We hypothesise...
Abstract Globally, inland waters emit over 2 Pg of carbon per year as dioxide, which the majority originates from streams and rivers. Despite global significance fluvial dioxide emissions, little is known about their diel dynamics. Here we present a large-scale assessment day- night-time fluxes at water-air interface across 34 European streams. We directly measured four times between October 2016 July 2017 using drifting chambers. Median are 1.4 2.1 mmol m −2 h −1 midday midnight,...
Abstract The trait‐based partitioning of species plays a critical role in biodiversity–ecosystem function relationships. This niche drives and depends on community structure, yet this link remains elusive the context metacommunity, where local assembly is dictated by regional dispersal alongside environmental conditions. Hence, elucidating coupling structure needs spatially explicit studies. Such studies are particularly necessary river networks, habitats highly connected unidirectional...
Abstract Biodiversity underpins the functional integrity of ecosystems. At present, our understanding relationship between biodiversity and ecosystem functioning (BEF) is essentially based on manipulative experiments. Compelling data at large spatial scales are scarce, especially for river networks. BEF patterns across landscapes complex because they unfold in context environmental gradients compositional turnover natural communities. Leaf litter decomposition, a pivotal process streams, no...
Abstract Biodiversity and functioning often follow spatial gradients, yet with unclear causal linkage. In spatially complex rivers, regional-scale factors associated hydrological connections catchment properties control downstream transport of material dispersal organisms, both being crucial for ecosystem functioning. a single snapshot study, we here show how river’s network structure interacts its terrestrial matrix to key environmental conditions periphyton community composition at the...
Abstract Aim Although running waters are getting recognized as important methane sources, large‐scale geographical patterns of microorganisms controlling the net balance streams still unknown. Here we aim at describing community compositions methanogenic and methanotrophic large spatial scales linking their abundances to potential sediment production (PMP) oxidation rates (PMO). Location The study spans across 16 European from northern Spain Sweden western Ireland Bulgaria. Taxon...
Globally, inland waters emit over 2 Pg of carbon (C) per year as dioxide (CO2), which the majority originates from streams and rivers. Despite global significance fluvial CO2 emissions, little is known about their diel dynamics. We present first large-scale assessment day- night-time fluxes at water-air interface across European streams. Fluxes were directly measured four times throughout one using drifting chambers. Median amounted to 1.4 2.1 mmol m-2 h-1 midday midnight, respectively, with...
Abstract Meta-ecosystem theory predicts that cross-ecosystem flows of energy, nutrients, and organisms have important implications for local community assembly ecosystem functioning. Developments in the also potential to enhance our under-standing biodiversity-ecosystem functioning relationships. is particularly well-suited study rivers, because water flow forces strong spatial interrelationships among connected ecosystems. However, models address both resources explicitly link are lacking....
Abstract Benthic bacteria in stream ecosystems drive organic matter mineralization. However, knowledge on how this ecosystem function is driven by bacterial community composition interaction with environmental conditions and resources poor. This especially true when considering the regional scale of river networks, at which vary a scale‐dependent manner are spatially structured due to asymmetrical water flow. Similarly, may have terrestrial origin remote headwaters or be sourced locally from...
Abstract Background: Globally, streams emit significant amounts of methane, a highly potent greenhouse gas. However, little is known about the stream sediment microbial communities that control net methane balance in these systems, and particular their distribution composition at large spatial scales. This study investigated diversity abundance methanogenic archaea methane-oxidizing microorganisms across 16 European (from northern Spain to Sweden from western Ireland Bulgaria) via 16S rRNA...

Abstract In many regions around the world, large populations of native wildlife have declined or been replaced by livestock grazing areas and farmlands, with consequences on terrestrial-aquatic ecosystems connectivity trophic resources supporting food webs in aquatic ecosystems. The river continuum concept (RCC) riverine productivity model (RPM) predict a shift carbon supplying along river: from terrestrial inputs low-order streams to autochthonous production mid-sized rivers. Here, we...
