Journal ArticleDOI

TL;DR: The integrative analysis aims to compare how molecular and physiological mechanisms related to protection, repair and energy allocation can impact life history traits of stressed organisms, and to what extent trait responses influence individual and population responses.
Journal ArticleDOI
Influence of toxic cyanobacteria on community structure and microcystin accumulation of freshwater molluscs.
TL;DR: Observed decrease in mollusc abundance and changes in species richness in highly contaminated waters were not significant; however, relative abundances of taxa (prosobranchs, pulmonates, bivalves) were significantly different before and after cyanobacterial bloom.
Journal ArticleDOI
Interactions between cyanobacteria and Gastropods I. Ingestion of toxic Planktothrix agardhii by Lymnaea stagnalis and the kinetics of microcystin bioaccumulation and detoxification
TL;DR: Toxin accumulation was greater in the gastropods fed on P. agardhii alone than those fed on the mixed diet, and was also greater in juveniles than in adults, and the results are discussed in terms of potential contamination to the food web.
Journal ArticleDOI
Accumulation of free and covalently bound microcystins in tissues of Lymnaea stagnalis (Gastropoda) following toxic cyanobacteria or dissolved microcystin-LR exposure.
TL;DR: Following the accumulation of total MCs in Lymnaea stagnalis exposed to dissolved MC-LR, bound MCs were detected in snails previously exposed to toxic cyanobacteria, representing a potential source of MCs transfer through the food web.
Journal ArticleDOI
Long‐term dynamics and community structure of freshwater gastropods exposed to parasitism and other environmental stressors
TL;DR: In this paper, the gastropod community of a French lake has been investigated for 10 years to study its responses to three main environmental disturbances: supra-seasonal droughts, recurrent proliferations of cyanobacteria and parasitism by trematodes.
