Effects Of Human-Driven Water Stress on River Ecosystems: a Meta-Analysis
(Nature Publishing Group, 2018-07-30)
Human appropriation of water resources may induce water stress in freshwater ecosystems when ecosystem needs are not met. Intensive abstraction and regulation cause river ecosystems to shift towards non-natural flow regimes, ...
Global pressures, specific responses: effects of nutrient enrichment in streams from different biomes
(IOP PUBLISHING LTD, 2013-01-09)
We assessed the effects of nutrient enrichment on three stream ecosystems running through distinct biomes (Mediterranean, Pampean and Andean). We increased the concentrations of N and P in the stream water 1.6–4-fold ...
Habitat Complexity in Aquatic Microcosms Affects Processes Driven by Detritivores
(Public Library Science, 2016-11-01)
Habitat complexity can influence predation rates (e.g. by providing refuge) but other ecosystem processes and species interactions might also be modulated by the properties of habitat structure. Here, we focussed on how ...
Testing Wastewater Treatment Plant Effluent Effects on Microbial and Detritivore Performance: a Combined Field and Laboratory Experiment
(Elsevier, 2018-10)
The amount of pollutants and nutrients entering rivers via point sources is increasing along with human population and activity. Although wastewater treatment plants (WWTPs) greatly reduce pollutant loads into the environment, ...
Determining diet from faeces: Selection of metabarcoding primers for the insectivore Pyrenean desman ( Galemys pyrenaicus )
(Public Library Science, 2018-12-14)
Molecular techniques allow non-invasive dietary studies from faeces, providing an invaluable tool to unveil ecological requirements of endangered or elusive species. They contribute to progress on important issues such as ...
Priming of leaf litter decomposition by algae seems of minor importance in natural streams during autumn
(Public Library Science, 2018-09-07)
Allochthonous detritus of terrestrial origin is one of the main energy sources in forested headwater streams, but its poor nutritional quality makes it difficult to use by heterotrophs. It has been suggested that algae ...
Global CO2 emissions from dry inland waters share common drivers across ecosystems
(Springer Nature, 2020-05-01)
[EN] Many inland waters exhibit complete or partial desiccation, or have vanished due to global
change, exposing sediments to the atmosphere. Yet, data on carbon dioxide (CO2) emissions
from these sediments are too scarce ...
Immediate and Legacy Effects of Urban Pollution on River Ecosystem Functioning: a Mesocosm Experiment
(Elsevier, 2019-03)
Effluents from urban wastewater treatment plants (WWTP) consist of complex mixtures of substances that can affect processes in the receiving ecosystems. Some of these substances (toxic contaminants) stress biological ...
Organic Matter Decomposition and Ecosystem Metabolism as Tools to Assess the Functional Integrity of Streams and Rivers–A Systematic Review
(MDPI, 2020-12-15)
Streams and rivers provide important services to humans, and therefore, their ecological integrity should be a societal goal. Although ecological integrity encompasses structural and functional integrity, stream bioassessment ...
Interactive effects of discharge reduction and fine sediments on stream biofilm metabolism
(James N. McNair, 2021)
Discharge reduction, as caused by water diversion for hydropower, and fine sediments deposition, are prevalent stressors that may affect multiple ecosystem functions in streams. Periphytic biofilms play a key role in stream ...
