Temperature Sensitivity of Microbial Litter Decomposition in Freshwaters: Role of Leaf Litter Quality and Environmental Characteristics
(Springer, 2023-05)
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 ...
Sea lamprey nests promote the diversity of benthic macroinvertebrate assemblages
(Public Library Science, 2022-12)
The habitat heterogeneity hypothesis states that increased habitat heterogeneity promotes
species diversity through increased availability of ecological niches. We aimed at describing
the local-scale (i.e. nest and ...
Tertiary wastewater treatment combined with high dilution rates fails to eliminate impacts on receiving stream invertebrate assemblages
(Elsevier, 2023-02)
he amount of wastewater processed in treatment plants is increasing following more strict environmental regulations. Treatment facilities are implementing upgrades to abate the concentrations of nutrients and contaminants ...
Resource preference of two stream detritivores in the laboratory largely differs from the supply of detritus below eucalypt plantations
(Springer, 2022-07)
Detritivores are pivotal in forest streams as they process detritus and promote secondary production. Many studies have addressed the preference of freshwater detritivores towards materials of differing quality. Nevertheless, ...
Food-web energy fluxes, energy transfer efficiency, and diversity respond distinctively to pollution and water diversion in rivers
(Wiley, 2024-03)
Water diversion and pollution are two pervasive stressors for river ecosystems that often co-occur. The individual effects of both stressors on river communities and energy transfer across the food webs are well described; ...
Using biological traits to assess diet selection: the case of the Pyrenean Desman
(Oxford University Press, 2023-12)
Traditionally, researchers have assessed diet selection by comparing consumed versus available taxa. However, taxonomic assignment is probably irrelevant for predators, who likely base their selection on characteristics ...
Land use drives detritivore size structure and decomposition through shifts in resource quality and quantity
(Elsevier, 2023-09)
Land use change and nutrient pollution are two pervasive stressors that can modify carbon cycling, as they influence the inputs and the transformation of detritus. Understanding their impact on stream food webs and on ...
Short-term effects of a large dam decommissioning on biofilm structure and functioning
(Wiley, 2023-01)
Aging dams and the rising efforts to restore stream ecosystems are increasing the number of dam decommissioning programs. Although dam decommissioning aims at improving in-stream habitat, biodiversity, and ecosystem ...
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 ...
Water diversion and pollution interactively shape freshwater food webs through bottom-up mechanisms
(Wiley, 2022-02)
[EN] Water diversion and pollution are two pervasive stressors in river ecosystems that often co-occur. Individual effects of both stressors on basal resources available to stream communities have been described, with ...
