Pandey, L.K. / Lavoie, I. / Morin, S. / Park, J. / Lyu, J. / Choi, S. / Lee, H. / Han, T. - 2018In the present study, the ecological status of four major South Korean rivers flowing near industrial complexes is assessed using physico-chemical analyses and various descriptors based on benthic diatom assemblages. Principal component analysis conducted with physical and chemical variables...Contributeur (s):

Lavoie, I. / Hamilton, P.B. / Morin, S. / Kim Tiam, S. / Kahlert, M. / Gonçalves, S. / Falasco, E. / Fortin, C. / Gontero, B. / Heudre, D. / Kojadinovic Sirinelli, M. / Manoylov, K. / Pandey, L.K. / Taylor, J.C. - 2017Contaminant-related stress on aquatic biota is difficult to assess when lethal impacts are not observed. Diatoms, by displaying deformities (teratologies) in their valves, have the potential to reflect sub-lethal responses to environmental stressors such as metals and organic compounds. For this...Contributeur (s):

Ouchir, N. / Morin, S. / Ben Aissa, L. / Boughdiri, M. / Aydi, A. - 2017An initial inventory of diatom biodiversity at 12 sites draining into Lake Ichkeul, northern Tunisia, was performed in summer 2014, together with the characterisation of metal pollution status by analysing trace metal concentrations to determine Water Quality Indices. The maximum values of Fe, Mn,...Contributeur (s):

Morin, S. / Lambert, A.S. / Planes Rodriguez, E. / Dabrin, A. / Coquery, M. / Pesce, S. - 2017tBiological communities in aquatic environments most commonly face multiple stress, where natural andanthropogenic stressors often act jointly. Their interactions are most easily assessed using short cycleorganisms such as periphytic diatoms.In this experiment, we analyzed the combined effects of...Contributeur (s):

Coquillé, N. / Morin, S. - 2017Diatom teratologies have intrigued scientists since the XIXth century, with respect to the causes and origins of their outbreak. They were mainly observed in long term cultures or under high pollution, and were poorly considered, except recently as a potential indicator of toxic impairment of...Contributeur (s):

Neury Ormanni, J. / Vedrenne, J. / Morin, S. - 2017A substantial amount of research has been dedicated to aquatic biofilms, but unlike the influence of macrograzers that of microscopic herbivores (2µm-2mm) has been largely disregarded. The selective pressure they may exert remains unexplored, despite its potential impact on microbial community...Contributeur (s):

Guasch, H. / Ricart, M. / Lopez Doval, J. / Bonnineau, C. / Proia, L. / Morin, S. / Munoz, I. / Romani, A.M. / Sabater, S. - 20171. Interactions between emerging contaminants and other drivers of community structure and function are poorly known. We used laboratory microcosms to investigate the single and combined effects of grazing and triclosan toxicity on the structure and function of stream periphyton. 2. Grazing alone...Contributeur (s):

A large set of methods derived from biofilm ecology has successfully been applied in ecotoxicology providing a diverse and comprehensive...Contributeur (s):

A major challenge in environmental risk assessment of pollutants is establishing a causal relationship between field exposure and community effects that integrates both structural and functional complexity within ecosystems. 2. Pollution-induced community tolerance (PICT) is a concept that...Contributeur (s):

Neury Ormanni, J. / Vedrenne, J. / Morin, S. - 2016/ L’Union Européenne représente 45% du tonnage mondial de pesticides. Une infime partie de ces pesticides atteint véritablement les sites d’action des organismes-cible, le reste se répartit dans l’environnement par le biais de divers phénomènes comme le ruissellement...Contributeur (s):

Cette notion de trame verte et bleue est le résultat d'...Contributeur (s):

Mazzella, N. / Morin, S. / Margoum, C. / Miège, C. / Lissalde, S. / Guibaud, G. / Coquery, M. - 2017Despite many efforts for improving the monitoring of an increasing number of chemicals (and their potential by-products), for a more comprehensive and exhaustive estimate of aquatic organism exposure, there is still some questions in relation with both temporal and spatial representativeness of the...Contributeur (s):

Chaumet, B. / Bernard, M. / Moreira, A. / Morin, S. / Mazzella, N. - 2016Because of their ubiquitous presence in aquatic environment, pesticides impact aquatic organisms, without being systematically accumulated. Although quantification methods for accumulated metals, and their uptake mechanisms, in biofilms are nowadays well known, they are poorly developed for organic...Contributeur (s):
