Effects of Acid Rock Drainage on Microbial Communities in Alpine Streams of the Pyrenees
Weathering of sulphur-bearing rocks leads to acid rock drainage (ARD), which decreases water pH, mobilizes heavy met als, and forms coloured coatings of metal precipitates on riverbeds. This study assessed the effects of ...
De los microplásticos a los aditivos: la contaminación invisible de nuestros océanos
¿Qué magnitud ha adquirido la contaminación por plásticos en el medio marino? Además de los residuos flotantes y visibles, deben tenerse en cuenta los microplásticos y los aditivos químicos que intervienen en su fabricación. ...
Assessing the potential impacts of floating Offshore Wind Farms on policy-relevant species: A case study in the Gulf of Roses, NW Mediterranean
Our study investigates for the first time how floating Offshore Wind Farms (OWFs) technologies could impact policy-relevant Mediterranean species, focusing on planned OWFs in the Cape Creus/Gulf of Roses (Spain, NW ...
Untangling the roles of centrality and environmental contribution in diversity patterns across spatial scales
The application of graph theory to metacommunity ecology allows a deeper analysis of the effect of network structure on diversity patterns. Here, we set out to test the role of network centrality metrics and environmental ...
Response of biofilm bacterial communities to antibiotic pollutants in a Mediterranean river
Antibiotics are emerging contaminants, which wing to their bioactivity, may lead to short-term and long-term alterations of natural microbial communities in aquatic environment. We investigated the effects of antibiotics ...
Resistance and recovery of river biofilms receiving short pulses of Triclosan and Diuron
The effects of the herbicide Diuron (DIU) and the bactericide Triclosan (TCS) were assessed on laboratory-grown stream biofilms. Four week-old biofilms were exposed in mesocosms to 48-hours of short pulses of either DIU ...
Seasonal Effects on Health Status and Parasitological Traits of an Invasive Minnow in Iberian Waters
Biological invasions are of special conservation concern in the Iberian Peninsula and other regions with high levels of endemism. Environmental variability, such as the seasonal fluctuations of Mediterranean streams, is a ...
Interaction between Physical Heterogeneity and Microbial Processes in Subsurface Sediments: A Laboratory-Scale Column Experiment
Physical heterogeneity determines interstitial fluxes in porous media. Nutrients and organic matter distribution in depth influence physicochemical and microbial processes occurring in subsurface. Columns 50 cm long were ...
Weak Coherence in Abundance Patterns Between Bacterial Classes and Their Constituent OTUs Along a Regulated River
Deductions about the ecology of high taxonomic bacterial ranks (i.e., phylum, class, order) are often based on their abundance patterns, yet few studies have quantified how accurately variations in abundance of these ...
Effects of large river dam regulation on bacterioplankton community structure
Large rivers are commonly regulated by damming, yet the effects of such disruption on prokaryotic communities have seldom been studied. We describe the effects of the three large reservoirs of the Ebro River (NE Iberian ...
Effects of a bactericide on the structure and survival of benthic diatom communities
We studied the adverse effects of triclosan, a widely used biocide commonly reported in surface waters, on the structure and function of benthic diatom communities. Laboratory-grown biofilms were exposed (i) to chronic ...
Adaptation of the European Fish Index (EFI+) to Include the Alien Fish Pressure
The European Fish Index EFI+ is the only fish-based multimetric index for the assessment of the ecological status of running waters that is validated and thus applicable across most countries of the European Union. Metrics ...
Importance of life history traits for vulnerability to climate change: implications for macroalgal restoration
Fucalean algae are dominant canopy-forming species that create extensive and highly productive ecosystems in the intertidal and subtidal rocky shores of temperate seas. Regrettably, these marine forests are in decline due ...
Two centuries of spatial and temporal dynamics of freshwater fish introductions
Aim Investigating major freshwater fish flows (translocations) between biogeographic regions and their temporal dynamics and also quantifying spatial patterns and temporal changes in the array of introduced species, and ...
Identification of potential invasive alien species in Spain through horizon scanning
Invasive alien species have widespread impacts on native biodiversity and ecosystem services. Since the number of introductions worldwide is continuously rising, it is essential to prevent the entry, establishment and ...
The importance of seawater tolerance and native status in mediating the distribution of inland fishes
Aim Unravelling the ecological and historical factors that underlie species distributions has challenged ecologists for a long time. Thus, our objective is to understand the role of environmental variables explaining the ...
Faecal microbiota and antibiotic resistance genes in migratory waterbirds with contrasting habitat use
Migratory birds may have a vital role in the spread of antimicrobial resistance across habitats and regions, but empirical data remain scarce. We investigated differences in the gut microbiome composition and the abundance ...
Individual body mass and length dataset for over 12,000 fish from Iberian streams
We provide a unique fish individual body size dataset collected from our own sampling and public sources in north-eastern Spain. The dataset includes individual body size measures (fork length and mass) of 12,288 individuals ...
Phylogenetic signal and evolutionary relationships among traits of inland fishes along elevational and longitudinal gradients
Understanding the main drivers of species distributions is one of the main goals of ecology. However, the relationships between traits and elevational and longitudinal distributions in inland fishes, as well as their ...
Global dispersal and potential sources of antibiotic resistance genes in atmospheric remote depositions
Antibiotic resistance has become a major Global Health concern and a better understanding on the global spread mechanisms of antibiotic resistant bacteria (ARB) and intercontinental ARB exchange is needed. We measured ...
