ABC model for estimating sea lamprey local population size using a simple nest count during the spawning season
(EDP Sciences, 2023-02)
Population estimation implies considering the biology of the species, but also the constraints of logistic aspects such as cost. While common methods based on individual counts can provide precise estimates, they require ...
The drawdown phase of dam decommissioning is a hot moment of gaseous carbon emissions from a temperate reservoir
(Taylor & Francis, 2022)
Dam decommissioning (DD) is a viable management option for thousands of ageing dams. Reservoirs are large carbon sinks, and reservoir drawdown results in important carbon dioxide (CO2) and methane (CH4) emissions. We studied ...
Slow drawdown, fast recovery: Stream macroinvertebrate communities improve quickly after large dam decommissioning
(Wiley, 2024-06)
Dam removal is increasingly considered as a river restoration tool for impoundments that harm the environment or have exceeded their lifespan. However, few studies report the ecological consequences of large dam removal.

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 ...
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 ...
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, ...
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 ...
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 ...
