River ecosystems are subject to multiple stressors that affect their structure and functioning. Ecosystem refers characteristics such as channel form, water quality or the composition of biological communities, whereas ecosystem functioning processes metabolism, organic matter decomposition secondary production. Structure respond in contrasting complementary ways environmental stressors. Moreover, assessing response is critical understand effects on services produce direct benefits humans....
Despite predicted global warming, the temperature effects on headwater stream functioning are poorly understood. We studied these microbial-mediated leaf decomposition and performance of associated aquatic hyphomycete assemblages. Alder leaves were incubated in three streams differing winter water temperature. Simultaneously, laboratory, discs conditioned at 5, 10 15 °C. determined mass loss, N sporulation rate diversity communities. In field, correlated positively with Decomposition...
Abstract Leaf litter breakdown is a key process, providing matter and energy to communities inhabiting many headwater streams that flow through forests. This detrital pathway affected by human landscape transformations; but it little known about the impact of small reservoirs on leaf decay in streams. Alder rates associated fauna were studied upstream downstream five water supply (surface‐release rainy autumn‐winters), Nerbioi‐Ibaizabal drainage basin (Basque Country, Spain), assess effect...
Abstract Large variability in dissolved organic carbon (DOC) uptake rates has been reported for headwater streams, but the causes of this are still not well understood. Here we assessed acetate across 11 European streams comprising different ecoregions by using whole‐reach pulse additions. We evaluated main climatic and biogeochemical drivers during two seasonal periods. Our results show a minor influence sampling periods strong effect climate matter (DOM) composition on uptake. In...
Summary Water abstraction is rapidly increasing worldwide in order to respond escalating demands for water, food and energy. Abstraction can alter the hydrological regime of streams rivers, reduce in‐stream habitats, change water quality affect fluvial communities. It also impair ecosystem functioning, although this aspect has been seldom assessed. We experimentally tested effect on stream functioning a headwater mountain using before after control‐impact (BACI) design. quantified changes...
Abstract Biodiversity loss is occurring globally at unprecedented rates, altering the functioning of Earth's ecosystems. Multiple processes are often key components ecosystem functioning, but it unclear how biodiversity affects multifunctionality (i.e., ability ecosystems to maintain multiple simultaneously). This particularly true for some types such as streams, which have been understudied, despite their role in global biogeochemical cycles and serious impairment by widespread riparian...
Although temporary streams represent a high proportion of the total number and length running waters, historically study intermittent has received less attention than that perennial ones. The goal present was to assess effects flow cessation on litter decomposition in calcareous under oceanic climate conditions. For this, leaf alder incubated four (S1, S2, S3 S4) with different regimes (S3 S4 zero-flow periods) from northern Spain. To distinguish relative importance contribution decomposers...
Biodiversity loss in riparian forests has the potential to alter rates of leaf litter decomposition stream ecosystems. However, studies have reported full range positive, negative and no effects plant diversity on decomposition, there is currently explanation for such inconsistent results. Furthermore, it uncertain whether affects other ecological processes related as fine particulate organic matter production or detritivore growth, which precludes a thorough understanding how detrital food...
Summary In low‐order forested streams, catchment‐scale land‐use modifications to vegetation can affect energy inputs into streams and trophic interactions within these donor‐controlled food webs. We examined the effects of Pinus radiata plantations on intercept slope size spectrum (the relationship between log‐mass log‐density) macroinvertebrate communities in streams. compared three draining pine with native deciduous forests, all without significant differences water physicochemical...
The replacement of native vegetation by exotic species has the potential to impact detritus based stream ecosystems. To test possible consequences alteration on ecosystem functioning we com- pared processing rate and invertebrate colonisation leaves from fi ve different tree species, two natives (Alnus glutinosa Quercus pyrenaica) three exotics (Populus × canadensis, Platanus hispanica Pinus radiata) in unaltered forested streams Atlantic region northern Spain.

Abstract Salinisation (i.e. increased ion concentrations) in fresh waters is a growing threat worldwide that impacts freshwater communities. However, less known about how salt concentrations affect key ecosystem processes such as leaf decomposition. We designed laboratory experiment to assess the effects of concentration gradient (1, 3, and 6 g/L) three different salts (NaCl, CaCl 2 CH 3 CO K), on litter decomposition mediated by microbial decomposers larvae cased caddis fly ( Schizopelex...
Ongoing global warming is expected to alter temperature-dependent processes. Nevertheless, how co-occurring local drivers will influence temperature sensitivity of plant litter decomposition in lotic ecosystems remains uncertain. Here, we examined the microbial-mediated decomposition, microbial respiration, fungal biomass and leaf nutrients two species varying quality. We also assessed whether type community stream water characteristics such responses temperature. incubated alder (Alnus...
Abstract The increase in the flow of fine sediments to aquatic ecosystems (AH), as a consequence human activities, is widespread stressor that may alter structure biological communities and ecosystem processes. In this study, effects (Ø < 2 mm) on (biomass composition) activity (decomposer sporulation rate) litter‐associated microorganisms (mainly AH) were investigated. For this, leaf discs in‐stream preconditioned Quercus robur incubated microcosms for 30 days under influence four...
Abstract Secondary salinization is a growing concern for freshwaters worldwide. The lethal and sub-lethal effects on shredders are known, but not whether these result from direct exposure to contaminated aquatic medium and/or indirect of distinct substrate quality through fungal conditioning in salinized media. Here, chestnut oak leaves were conditioned 4 weeks reference (Cond0, 0 g/l NaCl) or (Cond3, 3 media before being offered the shredder Schizopelex festiva maintained (Inv0) (Inv3)...
