Technological progress and advanced insights into epigenetic processes have led to the description of epigenetic features (mainly DNA methylation) in many ecologically relevant species: algae, plants, several invertebrates and fish. Epigenetic changes in plants, insects and cladocerans have been reported to be induced by various environmental stress factors including nutrition or water deficiency, grazing, light or temperature alterations, social environment, and dissolved organic matter concentrations. As regards chemicals, studies in rats and mice exposed to specific pesticides, hydrocarbons, dioxins, and endocrine disrupting chemicals demonstrated the induction of epigenetic changes, suggesting the need for further research with these substances in an ecotoxicological context. In fish and plants, exposure to polyaromatic hydrocarbons, metals, and soluble fractions of solid waste affected the epigenetic status. A novel concept in ecotoxicological epigenetics is the induction of transgenerational stress resistance upon chemical exposure, as demonstrated in rice exposed to metals. Evaluating epigenetics in ecotoxicological field studies is a second relatively new approach. A cryptic lineage of earthworms had developed arsenic tolerance in the field, concurrent with specific DNA methylation patterns. Flatfish caught in the framework of environmental monitoring had developed tumours, exhibiting specific DNA methylation patterns. Two main potential implications of epigenetics in an ecotoxicological context are (1) the possibility of transgenerationally inherited, chemical stress-induced epigenetic changes with associated phenotypes and (2) epigenetically induced adaptation to stress upon long-term chemical exposure. Key knowledge gaps are concerned with the causality of the relation between epigenetic and phenotypic changes, the persistence of transgenerational effects, the implications at population level and the costs of tolerance. Epigenetic changes following exposure to multiple stressors constitute another promising area of further research.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Epigenetics in an ecotoxicological context","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-02 01:32:41.308061","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":" Chemicals; Stress ecology; DNA methylation; Phenotype; Epigenetic changes; Transgenerational stress resistance","OtherDescriptors":null,"Notes":null,"AnaPub":2014,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2017-06-09","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000336341400005","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.mrgentox.2013.08.008"},"refs":null,"anarec":{"AnaID":286157,"PubliDate":2014,"Pagination":"36-45","XtraPublOfAnaID":null,"ISBN":null,"Volume":"764-765","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45604,"SerRR":"Mutation Research.
