Abstract River networks contribute disproportionately to the global carbon cycle. However, estimates of emissions from inland waters are based on perennial rivers, even though more than half world's river length is prone drying. We quantified CO 2 and CH 4 flowing water dry riverbeds across six European drying (DRNs, 120 reaches) three seasons identified drivers using local regional variables. Drivers differed between non‐perennial reaches, both were controlled partly by annual severity,...
<title>Abstract</title> The Mekong River, a global freshwater biodiversity hotspot, has suffered from intensive barrier construction, resulting in major challenges safeguarding its fauna. Here, we provide comprehensive evaluation of the impacts river barriers on distribution 1,032 fish species Basin. Our analysis revealed that 93% suffer habitat fragmentation, and with larger range requirements experienced higher fragmentation impacts. Sub-basins along main channel Lower had high values...
Abstract Stream metabolism is a key biogeochemical process in river networks, synthesizing the balance between gross primary production (GPP) and ecosystem respiration (ER). Globally, more rivers streams are drying due to climate change water abstraction for human uses this can alter organic carbon residence time leading decoupled ER terrestrial matter supply. Although consequences of on CO 2 emissions have been recently quantified, its effects stream still poorly studied. We addressed...
Abstract River ecosystem metabolism plays a significant role in the global carbon cycle. However, limited spatial or temporal scale of most river studies hinders our ability to draw general patterns, identify common drivers, and make reliable predictions. We developed Random Forest models for predicting daily rates using large database more than 100 reaches across Iberian Peninsula covering environmental gradient. As potential we included static variables (e.g., catchment area, distance...
Rivers are very vulnerable to fragmentation caused by the presence of man-made barriers. To restore river basin connectivity, numerous indices have been developed calculate and optimise barrier mitigation actions. These methods usually connectivity for whole basins, but sometimes it is useful analyse certain elements interest. The main goal this study was develop a simple method specific riverine habitats or fish meta-populations. framework Dendritic Connectivity Index (DCI) created Cote et...
Different indices have been developed to quantify the extent and severity of river fragmentation. These vary depending on specific goals study. Here, we present a new Conservation Connectivity Index (CCIP) for potamodromous fish species that considers conservation value (richness, rarity vulnerability) segments. The Iberian Peninsula holds > 20 endemic endangered as well 1000 large dams (> 1 hm3 capacity). CCIP was calculated eight most important basins compared Dendritic (DCIP) by Cote et...
Abstract Many human activities in and on rivers cause the loss of freshwater biodiversity, especially fish, which now are one most endangered vertebrate groups. River fragmentation caused by construction dams is main threats to fish species. In Spain, has highest number per square kilometre world, more than half all species threatened these constructions. The government initiated National Strategy for Restoration, a plan restore preserve their inhabitants, includes removal dams. An...
River fragmentation is one of the main threats to diadromous fish species. We aimed create a new and simple connectivity index calculate habitat accessibility that considers suitability for species, using Bidasoa basin in north Spain Atlantic salmon (Salmo salar) as an example. A (HCI) was calculated river upstream passability segment length variables. then quality each multiplied it by Breeding Habitat Connectivity Index (HCIb). These 2 indices were first only barrier adding downstream...
Barriers to longitudinal river connectivity: review of impacts, study methods and management for Iberian fish conservationRiver connectivity is essential the correct functioning freshwater ecosystems at all scales.However, it has not received necessary attention by researchers, managers policymakers until recent years.In this review, we recap state knowledge in its applications conservation.We describe particular characteristics summarise effects interruption different ecosystem elements.We...
Abstract The study of freshwater fish species biodiversity and community composition is essential for understanding river systems, the effects human activities on rivers, changes these animals face. Conducting this type research requires quantitative information abundance, ideally with long-term series body measurements. This Data Descriptor presents a collection 12 datasets containing total 146,342 occurrence records 41 sampled in 233 localities various Iberian basins. also contain 148,749...
The signal crayfish Pacifastacus leniusculus Dana, 1852 is a successful invasive species in the Iberian Peninsula. This of particular conservation concern, as fish fauna highly endemic and also threatened within this ecoregion. aim study was to analyze behavioral interactions trophic overlap between native fishes rivers (northern Spain). Video cameras were used record “dominance/evasion” after spatial encounters with crayfish. Diet composition isotopic signatures (δ13C δ15N) compared...
Stream metabolism is a key biogeochemical process in river networks, synthesising the balance between gross primary production (GPP) and ecosystem respiration (ER). Globally, more rivers streams are drying due to climate change water abstraction for human uses this can alter organic carbon residence time, leading decoupled ER terrestrial matter supply. While consequences of on CO2 emissions have been recently quantified, its effects stream still poorly studied. We addressed short- long-term...
Abstract Rivers receive substantial amounts of terrestrial organic carbon and a large fraction is released as CO 2 or CH 4 to the atmosphere. Global estimates emissions from inland waters are based on perennial rivers, although more than half global river length prone flow intermittence (lacking flowing water part year). The contraction phase, with final fragmentation networks by drying non-perennial reaches, can reduce promote at local-(river reach) regional-(river network) scale. We...
In business, the “long-tail economy” refers to a market strategy where gravity center shifts from few high-demand products many, varied focused on small niches. Commercialization of individually low-demand can be profitable as long their production cost is low and, all taken together, they aggregate into big chunk market. Similarly, in “business” biodiversity data acquisition, we find several mainstream that produce zillions bits information every year and account for most budget allocated...
