Advancing impact prediction and hypothesis testing in invasion ecology using a comparative functional response approach (2014, background): “…the feeding rates of invaders in comparison to natives, studies most often choose a prey density, or provide prey in excess, and measure prey consumed per unit time (e.g. Kelly et al. 2002; Fielding et al. 2003; Renai and Gherardi 2004; Rehage et al. 2005; Olden et al. 2009; Stoffels et al. 2011).”
Invasive crayfish in Europe: the impact of Procambarus clarkii on the littoral community of a Mediterranean lake (2007, unknown): “In fact, apart from ideal conditions in very small temporary pools (Ilhéu, Bernardo & Fernandes, 2007), the opportunistic P. clarkii usually feeds only on dead, dying or immobilised fish (Lowery & Mendes, 1977; Renai & Gherardi, 2004) and on eggs (Xinya, 1995).”
Structure and dynamics of an invasive population of the red swamp crayfish (Procambarus clarkii) in a Mediterranean wetland (2007, background): “Finally, because of its aggressiveness and predatory ability, it poses threats to the native fauna (e.g. amphibians, Gherardi et al., 2001; Renai & Gherardi, 2004), including endangered indigenous crayfish, such as the white-clawed crayfish, Austropotamobius pallipes (Lereboullet, 1858).”
Coupling long‐term studies with meta‐analysis to investigate impacts of non‐native crayfish on zoobenthic communities (2006, unknown): “For example, the findings of Renai & Gherardi (2004) suggest that greater predatory efficiency of crayfishes in non-native environments may be a result of greater prey naivety.”
Crayfish invading Europe: the case study of Procambarus clarkii (2006, background): “In fact, under laboratory conditions P. clarkii was shown to consume amphibian larvae more efficiently than the indigenous A. pallipes (Gherardi et al. 2001; Renai and Gherardi 2004).”
Stable isotopes, mesocosms and gut content analysis demonstrate trophic differences in two invasive decapod crustacea (2005, unknown): “For example, introduced freshwater crayfish can have substantially different trophic impacts than their native counterparts (Nyström, Bronmark & Granéli, 1999; Renai & Gherardi, 2004), even for congeneric species (Lodge et al., 2000).”
Understanding the impact of invasive crayfish (2007, background): “…takes a significantly shorter time than the indigenous A. pallipes to capture Triturus vulgaris (Linnaeus) larvae and Rana esculenta Linnaeus tadpoles (Renai and Gherardi 2004); or (3) is not deterred by toxins contained in Californian newt [Taricha torosa (Rathke)] eggs (Gamradt and Kats 1996).”
