Sex-biased gene expression across tissues reveals unexpected differentiation in the gills of the threespine stickleback by Sylvestre, Florent, Aubin-Horth, Nadia, Bernatchez, Louis

“…Finally, the gills exhibit high levels of differentiation (5%), suggesting that sex should be considered in physiological and ecotoxicological studies of gill responses in fishes. We also find that sex-biased gene expression in hemizygous genes is mainly driven by a lack of dosage compensation. …”

Effects of Polystyrene Microplastic Exposure on Liver Cell Damage, Oxidative Stress, and Gene Expression in Juvenile Crucian Carp (<i>Carassius auratus</i>) by Xiangtong Li, Yuequn Huang, Wenrong Li, Chaoyang Deng, Weiyuan Cao, Yi Yao

“…These four components demonstrated a relatively high level of responsiveness to PS-MP exposure and can be employed as ecotoxicological indicators of microplastics. (3) This experiment evaluated five genes in three treatments, which found that PS-MPs had different effects on gene expression in the liver and the tested genes were involved in different response pathways associated with virulence. …”

Source distribution, ecological risks, and controlling factors of heavy metals in river sediments: Receptor model-based study in a transboundary river basin by Abu Reza Md Towfiqul Islam, Abu Hena Md Fazla Rabbi, Amit Hasan Anik, Rahat Khan, Md Abdullah Al Masud, Grara Nedjoud, Abubakr M. Idris, Md Naimur Rahman, Venkatramanan Senapathi

“…In the context of transboundary rivers, which constitute intricate fluvial ecosystems, the persistent threat of heavy metals (HMs) contamination poses significant risks to ecosystem health. In this study, ecotoxicological hazards, governing factors, and the distribution of nine HMs (uranium (U), lead (Pb), cadmium (Cd), nickel (Ni), chromium (Cr), manganese (Mn), iron (Fe), zinc (Zn), and copper (Cu)), as well as sediment characteristics (sand, silt, clay, organic matter, and pH) are assessed within the sediment. …”

iMulch: an investigation of the influence of polymers on a terrestrial ecosystem using the example of mulch films used in agriculture by Carmen Wolf, Mike Wenzel, Björn Fischer, Ralf Bertling, Erich Jelen, Dieter Hennecke, Karlheinz Weinfurtner, Martina Roß-Nickoll, Henner Hollert, Antonia Weltmeyer, Kristina Bitter, Pauline Ruiz, Dusica Banduka, Jochen Tuerk, Lars M. Blank

“…Incorporated in soil, mulch film microplastic showed retention of extractable pesticides. In the ecotoxicological tests, both film types showed no acute toxic effects in the earthworm Eisenia fetida and the springtail Folsomia candida. …”
