Integration of epigenetics into ecotoxicology: insights and fundamental research needs

open access: yesBiological Reviews, Volume 101, Issue 2, Page 826-847, April 2026.
ABSTRACT Epigenetics refers to heritable changes in genome function that occur without direct alterations to the DNA sequence. A multitude of environmental contaminants can influence the epigenetic marks of a genome. Changes of epigenetic marks including DNA methylation, histone modifications, and non‐coding RNAs can induce alterations at the gene ...

Prioritising research on endocrine disruption in the marine environment: a global perspective

open access: yesBiological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Methane‐Derived Carbon Contributes to Fish Biomass in a Deep, Eutrophic Reservoir

open access: yesFreshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Methanotrophic bacteria oxidise large amounts of biogenic methane produced in freshwater and bind the original methane carbon in their biomass. When these bacteria are consumed by other organisms, methane‐derived carbon enters food webs. Methane‐derived carbon can support a substantial part of invertebrate biomass in some freshwater ecosystems.

Live observation of the oviposition process in Daphnia magna.

open access: yesPLoS ONE, 2019
In favorable conditions, Daphnia magna undergoes parthenogenesis to increase progeny production in a short time. However, in unfavorable conditions, Daphnia undergoes sexual reproduction instead and produces resting eggs.

Drivers and food web effects of Gonyostomum semen blooms [PDF]

open access: yes, 2013
The flagellate Gonyostomum semen forms dense late-summer blooms in humic lakes and is a nuisance to swimmers because it forms a slimy coat on the skin, causing irritation in sensitive individuals. Increasing occurrence and bloom incidence of G. semen has

\(\it Daphnia\) carapace

open access: yes, 2019
Phänotypische Plastizität bezeichnet die Fähigkeit eines Organismus mit bestimmtem Genotyp unterschiedliche Phänotypen als Reaktion auf sich ändernde Umweltbedingungen auszuprägen. Eine Form der phänotypischen Plastizität sind induzierbare Verteidigungen, die Reaktion einer Art auf Anwesenheit von Prädatoren. Die Süßwasser-Krebs-Gattung \(\it Daphnia\)

Effects of Chronic Waterborne Nickle Exposure on Two Successive Generations of \u3cem\u3eDaphnia Magna\u3c/em\u3e [PDF]

open access: yes, 2004
In a 21-d chronic toxicity test in which an F0 generation of Daphnia magna were exposed to waterborne Ni, the noobservable-effect concentration (for survival, reproduction, and growth) was 42 μg Ni L-1, or 58% of the measured 21-d median lethal ...
