High mountain lakes : extreme habitats and witnesses of environmental changes
Los lagos de montana ofrecen oportunidades de estudio que van mucho mas alla de lo que su disposicion en el territorio y abundancia pudieran sugerir. En este articulo presentamos un breve resumen de… Expand
Plant invasion is associated with higher plant–soil nutrient concentrations in nutrient‐poor environments
Plant invasion is an emerging driver of global change worldwide. We aimed to disentangle its impacts on plant-soil nutrient concentrations. We conducted a meta-analysis of 215 peer-reviewed articles… Expand
Pharmaceuticals and Personal-Care Products in Plants.
Pharmaceuticals and personal-care products (PPCPs) derived from agricultural, urban, and industrial areas accumulate in plants at concentrations (ng to μg kg-1) that can be toxic to the plants.… Expand

A first case of temperature-dependent distribution of polybromodiphenyl ethers (PBDEs) in remote areas is shown. Analysis of these compounds in fish from Pyrenean lakes distributed along an… Expand
High Bacterial Diversity in Epilithic Biofilms of Oligotrophic Mountain Lakes
Benthic microbial biofilms attached to rocks (epilithic) are major sites of carbon cycling and can dominate ecosystem primary production in oligotrophic lakes. We studied the bacterial community… Expand
Pollutant Dehalogenation Capability May Depend on the Trophic Evolutionary History of the Organism: PBDEs in Freshwater Food Webs
Organohalogen compounds are some of the most notorious persistent pollutants disturbing the Earth biosphere. Although human-made, these chemicals are not completely alien to living systems. A large… Expand
Spatial patterns reveal strong abiotic and biotic drivers of zooplankton community composition in Lake Mývatn, Iceland
Spatial patterns in the abundance of species are determined by local abiotic and biotic conditions, and by the movement of individuals among localities. For species distributed among discrete habitat… Expand
Concentration changes of organochlorine compounds and polybromodiphenyl ethers during metamorphosis of aquatic insects.
The role of insect larvae and pupae as sources of organochlorine compounds (OCs) and polybromodiphenyl ethers (PBDEs) in freshwater food webs for high predators such as fish is evaluated. Trichoptera… Expand
Global biodiversity, stoichiometry and ecosystem function responses to human-induced C-N-P imbalances.
Global change analyses usually consider biodiversity as a global asset that needs to be preserved. Biodiversity is frequently analysed mainly as a response variable affected by diverse environmental… Expand
Nitrogen-Cycling Genes in Epilithic Biofilms of Oligotrophic High-Altitude Lakes (Central Pyrenees, Spain)

Microbial biofilms in oligotrophic environments are the most reactive component of the ecosystem. In high-altitude lakes, exposed bedrock, boulders, gravel, and sand in contact with highly oxygenated… Expand
