Air-dried alder leaves were weighed (3 g for each microcosm) and leached in 105 labeled containers filled with 500 ml distilled water for 2 days. Julia Reiss, ... Cláudia Pascoal, in Advances in Ecological Research, 2010. This may not only affect the reproductive success but also leads to unbalanced population growth. However, such interactions may nonetheless lead to higher impacts on native prey populations through native predator enhancement (Noonburg and Byers, 2005). This lipophilic pyrene is easily transported through the hemolymph into the eggs, where it becomes toxic. Les gammares sont capables de percevoir la présence de prédateurs ; Anderson & al (1986) ont montré qu'ils deviennent moins actifs et sont moins nombreux à se laisser dériver dans le courant si des chabots (Cottus gobio) sont introduits dans leur environnent, l'un de leurs principaux prédateurs [5]. Newly hatched juveniles leave the marsupium shortly before the female molts, after which the females lays a new batch of mature oocytes that are immediately fertilized by a male. M.C. Boudreau and Yan, 2003; Kaufman, 1992), and a species-poor community can be quite resistant to being disrupted by invasion (e.g. 2017) Le gammarus pulex est omnivore.
