Fecha de publicación: | 12-mar-2019 | Editor: | Springer Nature | Citación: | Environmental Science and Pollution Research 26: 11496–11502 (2019) | Resumen: | Growth regulator insecticides with juvenoid activity can affect the development and reproduction of non-target organisms such as crustaceans. In this perspective, our previous studies revealed deleterious effects of the juvenoid fenoxycarb at 5 μg L −1 on the embryogenesis and at 50 μg L −1 on the reproductive behavior of the amphipod Gammarus fossarum. In the present study, to determine whether data generated with one amphipod species can be extended to other gammarid species, we tested the effects of a 5 μg L −1 fenoxycarb exposure on three European amphipod species: G. fossarum, Gammarus roeseli, and Echinogammarus longisetosus. We exposed individually 60 freshly fertilized females to fenoxycarb throughout the entire oogenesis/embryogenesis cycle (i.e., 19 days). In newborn individuals from exposed embryos, we measured both pigmentation and lipid reserve impairments while in exposed females, we observed reproductive behavior. At 5 μg L −1 fenoxycarb, reproductive behavior was only altered in G. fossarum. This study demonstrates the variability of the toxic response among the three gammaridae species, underlining the need for acquiring data with a broad phylogenetic representation to better predict toxic effects on freshwater ecosystems. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature. | Versión del editor: | https://doi.org/10.1007/s11356-019-04631-2 | URI: | http://hdl.handle.net/10261/202937 | DOI: | 10.1007/s11356-019-04631-2 |
