“…diet, temperature, pathogen prevalence) on offspring performance has been described for a long time (Curley, Mashoodh, & Champagne, 2011;Mousseau, 1998) but an increasing number of studies have revealed that parental age can also negatively impact F I G U R E 2 Breeding rate according to individual's age offspring survival (Fox, Bush, & Wallin, 2003;Priest, Mackowiak, & Promislow, 2002) and reproduction (Bouwhuis, Charmantier, Verhulst, & Sheldon, 2010;Ducatez et al, 2012;Lippens, Faivre, Lechenault, & Sorci, 2017;Priest, Roach, & Galloway, 2008;Schroeder, Nakagawa, Rees, Mannarelli, & Burke, 2015). For instance, in Asian elephants (Elephas maximus), older mothers produce offspring with impaired survival (Reichert et al, 2019) and in the rotifers Brachionus manjavacas, maternal age negatively affects offspring survival and reproduction (e.g. egg quality) (Bock, Jarvis, Corey, Stone, & Gribble, 2019).…”
