A proximate cue for oviposition site choice in the bitterling (Rhodeus sericeus) (2001, background): “ Smith et al. (2000a) proposed two proximate cues that bitterling may use to choose a mussel for oviposition site choice.”
Male-male interference competition decreases spawning rate in the European bitterling (Rhodeus sericeus) (2004, methodology): “The typical breeding-season fecundity in the study population is between 80 and 250 eggs per female (Smith et al. 2000a).”
Sexual signaling in the European bitterling: females learn the truth by direct inspection of the resource (2001, background): “Females have been found to avoid spawning in species of mussels with a high density-dependent mortality rate and in mussels that already contain large numbers of embryos (Smith et al., 2000).”
Complex signal function: developing a framework of testable hypotheses (2004, background): “Offspring survival has been shown to depend both on mussel species and on the density of embryos already present (Smith et al. 2000) and thus, it is important for females to assess mussel quality as well as male quality.”
Operational sex ratio and alternative reproductive behaviours in the European bitterling, Rhodeus sericeus (2003, background): “Females also prefer empty mussels over ones that contain bitterling embryos (Smith et al. 2000a; Candolin and Reynolds 2001), again reflecting better survival of embryos (Smith et al. 2000b).”
