Abstract In many ecosystems, detritus is the dominant source of energy and driver ecosystem functioning. particular, in forested headwater streams, allochthonous (e.g. leaf litter, dead wood) constitute main for detritivores living primary producers contribute marginally to metabolism flows. We hypothesised that a low consumption benthic diatoms, high‐quality resource, could be major importance growth detritivores. these resources might represent an essential polyunsaturated fatty acids (...
Omics approaches (e.g., transcriptomics, metabolomics) are promising for ecological risk assessment (ERA) since they provide mechanistic information and early warning signals. A crucial step in the analysis of omics data is modeling concentration-dependency which may have different trends including monotonic linear, exponential) or biphasic U shape, bell shape) forms. The diversity responses raises challenges concerning detection significant effect concentration (EC) derivation. Furthermore,...
Standardized chronic toxicity tests are usually analyzed using a NOEC (no observed effect concentration) or ECx (x% calculation. However,these methods provide very little information for the material cost they entail. It has been proposed that biology-based methods, such as DEBtox approach, would make better use of data available. deals with energy balance between physiological processes, and gives insight on how compound disturbs it. We propose analysis can be further improved by estimating...
Abstract Phthalates are chemical products used as additives in the synthesis of plastics to increase their flexibility and resistance. Among most frequently detected phthalates environment is dibutyl phthalate (DBP). Although ubiquitous freshwater environments at concentrations ng/L µg/L range, studies on effects DBP Daphnia magna have overlooked potential exposure low (µg/L order) without solvent. Our work focuses chronic life history traits (survival, growth, reproduction) model species,...
In the context of long-term monitoring stream ecological quality at large spatial extent, it is important to assess overall reliability a biotic index and mitigate its uncertainty ensure effectiveness stakeholder assessments decisions. Only few studies have focused on uncertainties associated both design method used status different steps biological data acquisition. this study we investigated with multimetric (i.e., related parameter values because development dataset characteristics...
In aquatic ecosystems, the biocide triclosan represents a hazard for non-target microalgae. So far, algal responses were mainly investigated at apical levels hampering acquisition of holistic view on primary, adaptive, and compensatory stress responses. We assessed chlorophyte Scenedesmus vacuolatus to (growth, photosynthesis) molecular (transcriptome, metabolome) comparative pathway sensitivity analysis. For each responsive signal (contigs, metabolites), concentration-response curve was...
Omics technologies has opened new possibilities to assess environmental risks and understand the mode(s) of action pollutants. Coupled dose-response experimental designs, they allow a non-targeted assessment organism responses at molecular level along an exposure gradient. However, describing relationships on such high-throughput data is no easy task. In first part, we review software available for this purpose, their main features. We set out arguments some statistical modeling choices have...
As part of the ecological risk assessment associated with radionuclides in freshwater ecosystems, toxicity waterborne uranium was recently investigated microcrustacean Daphnia magna over a three-generation exposure (F0, F1, and F2). Toxic effects on daphnid life history physiology, increasing generations, were demonstrated at organism level under controlled laboratory conditions. These modeled using an approach based dynamic energy budget (DEB). For each three successive DEBtox (dynamic...
Abstract N-acetyl-β-D-glucosaminidase (NAGase) is important for crustaceans because the enzyme activity necessary molting process. The present study aimed to assess sensitivity of Palaemon serratus NAGase a set compounds diverse chemical families in context vitro exposures. Compounds representing different were selected according their abundance, impact environment, and relevance as disruptors In first step, four solvents (dimethylsulfoxide [DMSO], methanol, acetone, ethanol) tested...
The no-observed-effect concentration (NOEC) is known to be based on a wrong usage of hypothesis tests, and the use confidence intervals preferred. purpose present study provide an easy proper way interpret ecotoxicological tests simultaneous associated with commonly used Dunnett procedure, show how these may allow one infer ECx values (effective concentrations).
